General Trends: | General Trends: | ||
As pointed out in the previous report, the most striking and revealing aspect of the data collected is the dramatic fluctuation of seedlings of woody species from season to season and year to year. In general, it appears that saturated soil and standing water in the early spring influence nutrient uptake, soil oxygen and thus successful seed germination and subsequent survival over the growing period. For instance, the abundance of soil moisture in the spring and particularly the fall of 1975 retarded seedling survival and resulted in a dramatic decrease in actual numbers. The spring of 1976, however, was somewhat dry, but moisture conditions improved over the growing season. Consequently, numbers of individuals of most species increased. This trend continued through the spring of 1978 before a significant decrease in numbers of individuals of the various species occurred. - | As pointed out in the previous report, the most striking and revealing aspect of the data collected is the dramatic fluctuation of seedlings of woody species from season to season and year to year.

Now that two and a half years of air and soil temperature data have been collected for the Ottawa control site, it can be stated that while temperatures are not the same as in the Tower Woods, they are similar enough so that variations in seasonal cycles (such as soil moisture levels and plant species regeneration rates) can be attributed in part to temperature factors. In other words, cooler temperatures at one site compared to the other site may coincide well with higher moisture levels and greater seed germination, while warmer temperatures in one site compared to the other site may co-incide well with drier conditions and greater seedling mortality. | Now that two and a half years of air and soil temperature data have been collected for the Ottawa control site, it can be stated that while temperatures are not the same as in the Tower Woods, they are similar enough so that variations in seasonal cycles (such as soil moisture levels and plant species regeneration rates) can be attributed in part to temperature factors.

Winter Birds Davis-Besse: Most of the winter birds observed during the peninsula study area circuit were transient shore birds and ducks, the latter taking advantage of several open water holes.

Ottawa: The Ottawa site underwent an even greater reduction in both numbers of species and numbers of individuals, from 40 species to 27, and 372 individuals to 192 (Table C-5). Much of the decline in individuals was due to a reduction of mallards from about 100 in 1977 to only 10 in 1978, and a decline of grackles from 30 to 8.

Much of the decline in individuals was due to a reduction of mallards from about 100 in 1977 to only 10 in 1978, and a decline of grackles from 30 to 8. In spite of these large changes, species diversity was essentially unchanged; the smaller number of indivi-duals and species in 1978 was compensated for by a more even distribution of numbers across those species. Those species absent in 1978, but present the year before, cut across all taxa, with three species of sparrows and two species of flycatchers missing. The blue jay and brown-headed cowbird, both seen in all past years, were missing from both sites this year. Blue jay populations fluctuate widely in the northeast, in some years due to disease outbreaks. | ||

Changes in the environment which reduce the amount of structure, or layering, in the forest will cause a decrease in bird species diversity. This relationship only holds for resident, breeding birds; thus we have not considered migrants or transient feeders in our analyses. | C-5 know that species diversity is correlated with diversity of foliage height, or structural diversity, rather than plant species diversity (MacArthur and MacArthur, 1961).

Four supplemental locations on the Davis-Besse site are set up with non-recording rain gauges and read weekly to provide additional data on rainfall patterns. Station "0W" is the basic off-site reference station located in the Ottawa National Wildlife Refuge. This location was chosen because of its similar vegetative cover, proximity to Lake Erie, and upwind position (in terms of climatic normals). This station has a setting very similar to Station "A", on a margin of swamp area in a woods with complete canopy cover. | Four supplemental locations on the Davis-Besse site are set up with non-recording rain gauges and read weekly to provide additional data on rainfall patterns.

Interpretation of Data ENTIRE PERIOD. Throughout 1978 extremes in temperature were the distinguish-ing feature. The frigid cold of January and February was in sharp contrast to very warm readings in August and September. March and April were very cool, averaging well below normal. The cold spring retarded vegetation growth at least two weeks behind what would be considered normal'for the region. | Interpretation of Data ENTIRE PERIOD.

Humidity is given both in the terms of relative humidity (Figure D-31) and dew point (Figure D-32). Generally there was a high degree of week-to-week fluctuation.

E Environrnental Studies Center Bowling Green State University Bowkng Creen. Ohio 43401 a (419) 172-0207 ANNUAL REPORT TERRESTRIAL MONITORING PROGRAM JANUARY 1979 Preface During 1978, the first year that Davis-Besse Nuclear Power Plant was fully operational, terrestrial monitoring continued at both the Davis-Besse site and Ottawa National Wildlife Refuge (reference site) . Data were collected on soil, flora, fauna, and meteorology. As in previous years, interrelationships between soil moisture and germination and survival of seedlings were investigated. Trends appeared similar to other years. Saturated soil conditions in early spring appeared to influence nutrient uptake, soil oxygen, and thus successful germination, survival, and growth. Optimum moisture en-hanced seedling survival, while limited or excessive moisture in the spring or fall decreased survival. In the spring of 1978, saturated soils at both the Cooling Tower Woods and Ottawa reference site re- ' sulted in increased seedling mortality. Changing canopy conditions also were found to influence species composition. If stabilization of soil moisture occurs from the operation of the cooling tower, a more stable, shade-tolerant plant community could result. As in previous years, soil temperature and soil moisture data were taken at three peninsula sites, two cooling Tower Woods sites, and two Ottawa Wildlife Refuge control sites. Data for all five reporting years from the sumac community of the peninsula and the Fulton soil area of the Tower Woods have been summarized, graphically. l 1 i l 4
, Some general trends have been noted from the five years of data collected from these two areas. These trends show seasonal variations and changes which can be expected to occur in the Ful-ton soil area of the Tower Woods and the sumac community of the peninsula.
Organic matter remains relatively low in the sumac community as compared to the Fulton soil of the Tower Woods. In both areas, cation exchange capacity fluctuates with changes in organic matter. In the Fulton soil of the Tower Woods, fluctuations in organic matter and cation exchange capacity have shown that organic matter and clay both are partiall:r responsible for the cation exchange capacity in the Fulton soil. Soil moisture appears to be an important variable at both study sites. As indicated, spring, summer, and fall moisture conditions are critical to plant growth and survival. The Fulton soil of the Tower Woods has experienced extreme seasonal moisture variations, while soil moisture at the peninsula site exhibits more moderate changes. Data were collected on amphibians, reptiles, small and larger mammals, and birds. Small mammal populations fluctuated seasonally, and at the Davis-Besse and Ottawa sites were nonsynchronous, as observed in previous years. Reptile, amphibian, and Dinter bird populations and species diversity at both sites remained relatively stable. However, spring and summer bird populations decreased in diversity from the preceding year. Meteorological data were collected at three climatological stations at Davis-Besse, one station at the Ottawa site, and at 11
the Bowling Green State University inland reference station from January 6 to December 22, 1978. Data are presented in monthly climatological summaries and in graphic form depicting weekly in-terstation deviations. In time, it is these variations between stations that will be the basis for determining any signigicant long-term environmental impacts. The Davis-Besse facility was fully operational for only a e portion of the year. During most of the spring bird migration season the cooling tower was not in use. Consequently, any direct impact of the facility operations would have been of relatively short duration. For none of the parameters studied in the various communities did we fino any evidence of alteration or modification as a result of the cooling tower or other site operations. Variations between the Davis-Besse and Ottawa Refuge (control) sites were as great as variations within the communities. William B. Jackson Director and professor of Biology Editor i iii l l
1 ANNUAL REPORT DAVIS-BESSE TERRESTRIAL MONITORIUG CONTRACT JANUARY, 1979 A. plant Communities Ernest S. Hamilton During the spring and fall of 1978 seedlings of woody species were sampled at all permanent sites at both Davis-Besse and the Ottawa National Wildlife Refuge. This included the 213 permanent x 2M quadrats in the five wooded areas at Davis-Besse and the 180 quadrats at the Ottawa site (Fig. A-1 & A-2) . Davis-Besse Site: The vegetation and, soil moisture data presented represent a continuation of data included in previous reports. These additional data are summarized, and some comparisons with previous years are made. Cooling Tower Woods: tioisture conditions in both the Toledo and Fulton soils were very high in the spring of 1973, with 100% saturation lasting well into July (Fig. A-3 ) . Visual observations I indicated a wet surface in the Fulton soil and standing water in the areas of Toledo soils during much of the spring. The result-ing reduced aeration, particularly in the Toledo soil, undoubtedly reduced nutrient uptake, which in turn increased seedling mortality (Hamilton and Limbird, 1979). The late summer and fall of 1978 were characteri cd by some-what reduced soil moisture levels. This was particularly true in the Toledo soils, although some recharge was evident in the Fulton i soils. Moisture levels'in late fall from October throug'h the first part of November were zero, and noisture rechargo did not commence l
. .- - .= .--
l A-2 until the. middic of November (Fig. A-3 ) . These moisture conditions, particularly in the Toledo soils, are reflected by the decrease in total numbers of individuals of the various species surviving in the Fulton soils undoubtedly re-flect the absence of spring standing water. Celtis occidentalis thus is able to germinate successfully and persist under these conditions of better soil aeration. The success rate of individuals occurring on the two soils from spring to fall of 1978 is almost identical (approximately 831) and further exemplifics the critical nature of the spring moisture conditions. If moisture levels permit species to germinate and persist, then they appear to be able to survive the normal drying ! conditions imposed-during the lare summer and early fall. These same trends are evident from the yearly data presented in Figure A- 3 and Tables Al&2.Both the spring and fall periods of 1975 were very moist. Consequently, species that were able to i germinate. in the spring did not survive the unusually moist condi-tions that persisted during the growing season, and the success rate dropped to about 28%. The somewhat drier spring conditions of 1976 then facilitated an increase in numbers of individuals, many of which were able to survive the moderately moist conditions of the a-fall of 1976. The success rato during this period increased to approximately 79%. These same trends are illustrated when individual species are examined. Celtis occidentalis responds favorably to fluctuating
seasonal moisture conditions. Thus, in the Fulton soil, seedling taortality is' about 50% during the wet year of 1975. The increase 9
- - a. , _ __ _ _
d A-3 in numbers from the spring of 1976 through the spring of 1978 indi-cates that moisture conditions fall within this species' range of tolerance. The Toledo soils, however, appear to be too wet for survival of Celtis. If germination does occur, the seedlings do not survive. Cornus drummondi appears also to be intolerant of the wetter Toledo soils. Appare'ntly the dry fall of 1974 allowed some seed germination and survival, but higher moisture conditions in sub-sequent years prevented establishment.
-Ilackberry-Box Elder and Hackberry II Communities: The moisture profiles for these two communities are illustrated in rigure A-4.
i
- Soil moisture in general appears to be more stable and the extremes are not as pronounced as in the Cooling Tower Woods. The Hackberry-Box Elder community appears to have adequate moisture during the grow-ing season, even though it is somewhat lower and not as well drained as the Hackberry Il community. The more stable moisture conditions are reflected in the seedling data, particularly Celtis occidentalis.
This species has increased in numbers dramatically, with very little decline from spring to fall 1978. The success rate of almost 93% indicates nearly optimum soil moisture conditions throughout the grow-ing season. The absence of spring flooding allowed a high germination rate with high survival through the growing season (Tables A-3 & A-4). Acer ncqundo, however, is declining rapidly even though soil moisture should not be limiting. The 75% drop in numbers indicates
- some other factor. The response is undoubtedly to light, since
{ , i visual observations the last few years indicated the canopy closing I

s 1 l
A-4 over. This, coupled with increases in numbers and bulk of other species, produced an increase in shade, probably somewhat beyond the limits of tolerance for this species. Thus, even though there is an adequate seed source and ample moisture, light is restrict-ing the success of Acer negundo. The short-lived r.ature of this species, coupled with dying of the present mature trees, will fur-ther restrict it. Undoubtedly, it will be eliminated and replaced with Celtis in the foreseeable future. The Hackberry II community represents a developmental contin-uation from the Hackberry-Box Elder community. The earlier succes-sional species of Acer negundo and Prunus virginiana are non-impor-tant in this community even though moisture is adequate. Celtis occidentalis has again increased steadily in numbers in the seedling
layer in response to the somewhat moderate soil moisture conditions that lack the more violent fluctuations characteristic of the Cool-ing Tower Woods. The thicker soil horizons and better soil develop-ment undoubtedly contribute to this adequate moisture supply. Ottawa National Wildlife Refuge: This woods was previously described in last year's report. During 1978 seedlings of woody species were sampled for the first time in the spring and fall of the same year (Table A-5). This layer is definitely dominated by Rhus radicans which is characteristically a shade intolerant species. It would appear that previous high lake water levels produced saturated soil conditions for long periods of time. Consequently, many canopy species either are now dying out
, , or have already succumbed to the lack of oxygen and nutrient uptake.
Many large canopy openings are the result. These high light areas on the forest floor are now filled with poison ivy. Moisture con-
A-5 ditions during this sampling period appear somewhat moderate (Fig. A-5) with the result that wetter type species in the canopy, such as Quercus palustris and 2. macrocarpa are not surviving in the seedling layer. General Trends: As pointed out in the previous report, the most striking and revealing aspect of the data collected is the dramatic fluctuation of seedlings of woody species from season to season and year to year. In general, it appears that saturated soil and standing water in the early spring influence nutrient uptake, soil oxygen and thus successful seed germination and subsequent survival over the growing period. For instance, the abundance of soil moisture in the spring and particularly the fall of 1975 retarded seedling survival and resulted in a dramatic decrease in actual numbers. The spring of 1976, however, was somewhat dry, but moisture conditions improved over the growing season. Consequently, numbers of individuals of most species increased. This trend continued through the spring of 1978 before a significant decrease in numbers of individuals of the various species occurred. - The data also indicate the importance of other environmental factors that may overshadow soil moisture. This is particularly true of changing canopy conditions which directly influence the amount of light that penetrates to the forest floor. Successional species that may tolerate fluctuating or saturated spring moisture conditions are nevertheless eliminated when their light tolerance range is surpassed. Consequently, species composition in the various study areas is slowly changing. If soil moisture conditions are stabilized by input of moisture from plant operation, the process of I
]
A-6 natural succession may be increased and a chade tolerant and rela-tively stable community may be created. This hypothetical community would undoubtedly not be the true climax of the area, but would be maintalned by artificial conditions.
Conclusions:
No significant short-term effects on plant communities or dif-ferences between quadrats at the Davis-Besse and Ottawa sites can be determined from the data collected during the first operational year of the cooling tower. Data for the Hackberry I and Kentucky Coffee Treo communities also have been included (Tables A-6 & A-7) . However, due to the small size of these study areas, no conclusions have been made concerning these two communities. t Re ferences Hamilton, E.S. and A. Limbird. In Press.

ANNUAL REPORT DAVIS-BESSE TERRESTRIAL MONITORING CONTRACT
, JANUARY 1979 B. Soil Environments Arthur Limbird Department of Geography The monitoring of the soil environments ' follows the procedures described in previous reports. Soil temperatures and soil moisture valueu have been monitored on a weekly or continuous basis at the three peninsula sites, the two Cooling Tower Woods sitos, and the two Ottawa Wildlife Refuge control sites. Soil samples were secured 4 from the peninsula, Tower Woods, and Ottawa sites in summer and from the Tower Woods sites in fall and chemically analyzed as in previous repo r ts. Soil temperature data are reported for the whole of 1978, while soil moisture data cre reported for the period from the week o f J une 16, 1978, to November 24, 1978.
Soil Temperatures Weekly air and soil temperature averages were used as in previous reports to summarize the daily temperature changes and to discuss the seasonal changes which have occurred at the monitoring sites. The changes at 10, 20, and 50 cm. depths are assessed for each of the moni-toring sites. The sumac community on the peninsula, the Fulton soil e e area in the Tower Woods, and the Fulton soil area in the Ottawa Refuge l have continuous soil temperature records for the weeks of December 30, 1977, to December 22, 1978, which represents a continuation of the l data presented in the previous report. l-Soil temperatures fluctuated in response to air temperature l l , changes with the bufferir.g effect of the soil being more noticeable l l at'the 50 cm.' depth than at the shallower 10 and 20 cm. depths (Table B-1) . 1 I
The ranges in weekly soil temperatures decreased with depth except for a few weeks as discussed below (Figures B-1, B-2, and B-3). Temperature ranges in the soil peaked in the spring and became more uniform through the summer and fall, especially in the peninsula site. Peninsula Area: Soil temperatures in the sumac community of the peninsula area at the 10 cm. depth were somewhat warmer at the start of the data period for 1978 than for the same time in 1977. Tempera-tures remained below freezing until a rapid increase (9.7 0 F.) occurred during the last week of March. This increase coincides with the rapid . thawing in 1977 when a change of 10.4 0 p, occurred in the final week of March. A second large temperature increase occurred in the last week of April, 1978. Throughdut the rest of the spring, the summer, and the early fall, soil temperatures at 10 cm. changed much more gradually than in the early spring. The temperatures did not reach as high a level as in 1977, but fall cooling was delayed considerably in 1978 compared to the previous year. The temperature at 10 cm. was 40 0 F. at the end of November, 1978, in contrast with 330 F. for the same time in 1977. Soil moisture levels (see below for more complete discussion) were adequate at 10 cm. in both years, so the cooler summer temperatures and the warmer fall temperatures in 1978 than in 1977 can be attributed to the improved insulation of the increasing litter mat and to the tree canopy which has increased in thickness each reporting year. 'The range of soil temperatures at the 10 cm. depth also demonstrates the more uniform temperature values for 1978 (Figure B-1). While air temperature ranges were similar to previous years, the soil temperature range fluctuated markedly during the
spring warm-up and thaw period and then became more uniform for the rest of the 1978 reporting period compared to past years. The average soil temperature at the 20 cm. depth in the sumac community remained about the same as at the 10 cm. depth, except that it remained somewhat cooler in the spring and somewhat warmer in the late fall because the response to air temperatures was delayed compared to the shallower depth. Similar to the 10 cm. depth, a pronounced increase in temperature accompanied the end of March thaw. This same increase occurred in 1977. The temperature at 20 cm. cooled more slowly in 1978 than in 1977, reaching 43 0 F. by the end of Nov-ember compared to 31 0 F. for the previous year. Again, the warmer fall temperatures and the cooler summer temperatures compared to previous years can be attributed to shade and insulation factors of the sumac community. The range of temperatures at the 20 cm. depth snowed a decided peak during the spring warm-up period and then be-came much more uniform through the remainder of 1978 (Figure B-1). The average soil temperatures at the 50 cm. depth in the sumac community generally responded less to air temperature changes than at the 10 and 20 cm. depths. However, the end of March thaw was accompanied by an increase in the weekly average temperature of 5.70 F. During the spring and early summer, temperatures at 50 cm. were very similar to 1977, but peak temperatures were delayed until late summer in 1978 (week of August 18) compared to midsummer (week of July 16) in 1977. The temperature at 50 cm. cooled more slowly in the fall of 1978 than in the previous year, so that at the end of November, 1978, it was 450 F. compared to 39 0 F. in 1977. The
range of temperatures at the 50 cm. depth did not respond to the spring warm-up period, a situation similar to the previous year. Cooling Tower Woods: The average air temperature in the Tower Woods generally remained somewhat cooler than the peninsula area beginning with the spring thaw and continuing until late December. In 1977, the Tower Woods' air temperatures did not decline as rap-idly as in the peninsula area; thus the Tower Woods was warmer through the fall 1977 than the peninsula. However, in 1978 the Tower Woods' air temperatures did not exceed those of the peninsula area until the end of October and then again at the end of November. The generally lower air temperatures in the Tower Woods than in the peninsula area can be attributed to the more dense tree canopy in the Tower Woods which also contributes to a slower warming of the soils of the Tower Woods in the spring. The average soil temperature at 10 cm. responded to changes in air temperatures at the time of initial spring thaw during the week of March 31. The spring thaw was somewhat later than in 1977 and similar to the peninsula area for 1978. Perhaps more importantly, the soil temperature at 10 cm. did not warm to 400 F. until the last week in April, 1978, a delay of three weeks compared to the peninsula area in 1978 and to the Tower Woods in 1977. Peak temp-eratures were not reached until early September compared to late July for 1977. In addition, peak temperatures were about 3.5 0 7, lower than the previous year despito air temperatures which were as warm or. warmer than in 1977. The temperature at 10 cm. in the (- Tower Woods. cooled more rapidly in November than the peninsula area. r
The Tower Woods was more than 8 0 F. cooler than the peninsula by the end of November. However, by the end of December, the soil tempera-ture at 10 cm. in the Tower Woods was only 1 0 F. cooler than the corresponding temperature in the peninsula area. The range of soil temperatures at 10 cm. was similar to 1977 except the peak values for temperature range occurred earlier in 1978 (early March to early April) than in 1977 (mid-March to early May). The average soil temperature at 20 cm. varied in a manner similar to the 10 cm. depth. Spring thaw occurred in the last week of March in 1978 compared to about one week earlier in 1977. Similar to the 10 cm. depth, the temperature at 20 cm. warmed more slowly in the spring than in the peninsula area. The temperature in the Tower Woods reach-ed above 400 F. during the last week of April compared to three weeks earlier in the peninsula area in 1978 and two weeks earlier in the Tower Woods in 1977. The temperature at 20 cm. did not reach its peak until early September, 1978, compared to mid-July, 1977. While temperatures at 20 cm. in the Tower Woods reached approximately the same summer levels as in .the peninsula area, the temperatures cooled more rapidlyin November and early December than the peninsula area and registered about 8.50 P. cooler than the peninsula area in early December. The range of soil temperatures at 20 cm. was similar to 1977 except for peak. values in the spring which occurred about a month earlier in 1978 (second week in April) than in 1977 (third week in May) and were not as pronounced as in 1977. The soil temperatures at the 50 cm. depth generally warmed more slowly than the shallower depths in the Tower Woods and more slowly than the same depth in the. peninsula area. The soil thawed at the
50 cm. depth one week later in 1978 than in 1977 and did not reach a'400 F. average value until early May, 1978, compared to mid-April, 1977. Peak temperatures were not reached until late August, 1978, compared to late July, 1977: The range of temperatures at 50 cm. in the Tower Woods was somewhat higher overall than in 1977, but as in previous years, there was no spring peak in temperature ranges
in 1978. The overall delay in soil warming in the Tower Woods in 1978 4 compared to 1977 seems to have contributed to two general relation-ships in 1978: first, the cooler soil temperatures appear to have contributed to a delayed drying of the Tower Woods' soils: dryness in late summer and fall 1978 coincides with temperatures that were warmer for this time period than in 1977: and second, abundant moisture in the fall of 1977 carried over to spring, 1978, influenc-ing the germination rate of plant species (see Section A) . The late summer and fall dryness further had an effect on the regeneration rate or success rate of plants (see Section A) . Ottawa Control Area The average air temperatures at Ottawa were generally more similar-to the Tower Woods than to the peninsula areas temperatures were lower than in the peninsula area from the spring thaw in late March to the end of the data reporting period. The soil temperatures were not accurate during January to March,1978, and the remote re-
- cording thermograph was then recalibrated to more accurately record the soil temperatures (Table B-1).
The soil temperature at 10 cm. at the Ottawa site generally was warmer than the same depth in the Tower Woods. Temperatures reached
and 20 cm. depths. Now that two and a half years of air and soil temperature data have been collected for the Ottawa control site, it can be stated that while temperatures are not the same as in the Tower Woods, they are similar enough so that variations in seasonal cycles (such as soil moisture levels and plant species regeneration rates) can be attributed in part to temperature factors. In other words, cooler temperatures at one site compared to the other site may coincide well with higher moisture levels and greater seed germination, while warmer temperatures in one site compared to the other site may co-incide well with drier conditions and greater seedling mortality. Soil Moisture Soil moisture was recorded at the five monitoring locations at the Davis-Desse property and at the two control locations from the week of June 16 to the week of November 24, 1978. Soil moisture levels were generally more similar to 1975 and 1976 than to the drier year of 1974 and the wetter year of 1977. In order to best compare the three study areas in terms of patterns of moisture availability, the sumac community of the peninsula, the Fulton soil area of the Tower Woods, and the Fulton soil area of the Ottawa site were used (Table B-2). . At the beginning of the data period the sumac community showed the results of the high fall moisture levels in 1977 (see January, 1978, Annual Report) . Spring recharge was not needed in 1978 and taus the soil at the peninsula site was more moist in early summer, 1978, than for the same period in 1977. However, July, 1978, was drier than July, 1977, and despite relatively low actual evaporation levels, the soil began to dry out, especially at the 10 and 50 cm.
_g_ ( deptns. More precipitation in early August recharged partially the available moisture, especially at the 10 and 20 cm. depths. More precipitation in early September more fully recharged moisture levels after drier conditions in middle to late August. Moisture levels remained high to the end of the data period as precipitation generally exceeded actual evaporation from late September to the end of December. Soil moisture levels at the 10 cm. depth in the peninsula area decreased to critically low levels for a three week period in July and again for the last week of August, 1978; in 1977, no week ex-perienced critically low moisture levels. The low moisture levels were of relatively short duration and should not have adversely affected the growth of vegetation or the success rates of most seed-( ling species (see Section A). Soil moisture levels at the 20 cm. depth in the peninsula area did not decrease to the same critical levels as ' the 10 cm. depth. As in past years, the 20 cm. depth remained more moist than either the 10 or 50 cm. depths during the July dry period. While the soil at the 20 cm. depth was drier in 1978 than in 1977, the sustained moisture availability helped to maintain plant growth. Soil moisture levels at the 50 cm. depth in the peninsula area reached critically low levels by mid-July, partially recharged, reached critical levels again by mid-August, and then recharged fully by mid-September. The drying at the 50 cm. depth can be attributed to two factors: one, the reduced precipitation and increased evap-oration of July and mid-August; and two, a lowering of the water table which reduced upward capillary water movement and reduced moisture availability.
.t-Overall, the moisture levels in the peninsula area were lower
.than in 1977. However, this relationship mustabe put into perspec-tive. The actual et'aporation total for the growing season of 1978 was the lowest of the five reporting seasons of this study (Table B-3) .
As a result, actual evaporation exceeded precipitation by less than one inch making 1978 similar to 1975 and 1976 when precipitation and actual evaporation totals for the growing season were close to equal. Thus, moisture availability levels were quite similar for the three years during the growing season. In 1974, actual evaporation greatly exceeded precipitation making for a dry year relative to plant growth and regeneration. In 1977, precipitation greatly exceeded actual evaporation making for a wet year relative to plant growth and regen-eration. At the beginning of the data period the Fulton soil area of the Tower IJoods showed the results of the high fall moisture levels in 1977 (see January,1978, Annual Report) . Spring recharge was not needed to establish high moisture availability. In fact, in the other soil area of the Tower Woods (Toledo soil) high moisture levels and standing water tended to inhibit germination and seedling growth (see Section A). In contrast, increased actual evaporation and rela-tively low precipitation during July started the process of lowering moisture levels. Some recharge in early August and early September delayed the total drying of the soil profile until late September. Recharge did not begin until mid-November. The moisture levels were much lower during the growing season of 1978 than during the growing season of 1977. The dry fall contributed to the reduction of fall' plant seedlings (see Section A) . Soil moisture levels at the 10 cm. depth in the Tower Woods de-
3 creastd to critically low levels briefly in late July, again in mid-Augus1:, and in late September. The critically low levels continued until mid-November. In 1977, moisture did not reach critical levels at all during the growing season at the 10 cm. depth. The low moisture levels in the fall of 1978 may have been an important factor in plant seedling success rates (see Section A). Soil moisture levels at the 20 cm. depth in the Tower Woods decreased to critical levels briefly in late July, again in mid-August, - and in late September. Recharge did not begin until November. In 1977, no critical moisture levels occurred at the 20 cm. depth. These low moisture levels at the 20 cm. depth in the fall of 1978 may have an adverse ef fect on seedling success rates and may also contribute to abnormal moisture and plant germination conditions in the spring of 1979. Soil moisture levels at the 50 cm. depth in the Tower Woods de-creased to critical levels in mid-August, recharged briefly in late August, and then dried thoroughly and remained dry until the end of the data period. Thus, recharge from the surface which had contribut-ed to increasing moisture availability at the 10 and 20 cm. depths had not reached the 50 cm. depth by the end of November. The dryness of.1978 was contrary to the wetness ,of 1977 in the latter part of the growing season amd into the late fall. Overall,'the moisture levels in the Tower Woods were lower than in 1977. While actual evaporation was the lowest of the five growing seasons (1974-1978), precipitation was less than half that of 1977 (Taulo B-3). Each year actual evaporation has exceeded precipitation
in the Tower Woods during the growing season. The difference was the least in 1977 which was a moist year in the Tower Woods; the differ-ence was the greatest in 1974, a dry year in the Tower Woods. The difference in 1978 was the second lowest difference characterizing it as a moderately moist year from the standpoint of atmospheric moisture. However, precipitation was " bunched" in late June, early August, and early September with entirely dry weeks between. Dry conditions in 1978 occurred later than in 1976 (when dryness occurred in July and again in mid- to late August) making for contrasting moisture conditions as they affect plant growth and regeneration rates. Thus, the late 4 dry period of 1978 will probably have more of an effect on 1979 plant conditions than the earlier dry period of 1976 had on 1976 or 1977 plant conditions. The available moisture in the Fulton soil at the Ottawa control site was similar to the Tower Woods throughout the data period. The Ottawa soil dried out more thoroughly at the 10 and 20 cm. depths in July' than the Tower Woods, recharged less in late August and in mid-September than the Tower Woods, and recharged more slowly toward the end of the data period than the Tower Woods. At the 50 cm. depth drying and recharge occurred more slowly at Ottawa than in the Tower Woods.
-However, the same general patterns of moisture drawdowns and recharges a
demonstrate that the Ottawa control site- and the Tower Woods are quite similar in terms of moisture change and availability levels for plants. A comparison was made between peak moisture periods and the times of electrical generation at Davis-Besse. It was assumed that the cool-ing tower would be in operation during each period of generation. During June, soil moisture levels were high in the Tower Woods and at
- - -- .- . - ~ - - _ -
the peninsula area, despite no electrical generation during ttay or J une . Peaks in moisture in early August coincide with a major pre-cipitation interval during the week of August 4. In late August and
- early September, moisture levels in the Tower Woods and at the penin- '
sula area began to increase without the aid of a major precipitation interval. Precipitation during the week of September 8 further re-charged the relatively low moisture supply. Electrical generation from August 30 to September 5 may have had some influence on the in-creased moisture availability. However, other factors such as ideal
- atmospheric conditions must have triggered such a response. There are
- no other periods during 1978 in which soil moisture increased without a major precipitation interval.
i
, A comparison was made between time periods of high and low moist-t ure levels in the peninsula area and water levels of the marsh area east of the Davis-Besse intake canal during 1978. The highest water level in the marsh was 572.45 feet during the weeks of April 7 and April
- 14. The lowest level was 570.60 feet during the week of June 2. The range of water levels was 1.85 feet for the year. The average water level was 571.51 feet based on 42 water level readings during the year.
An examination of high and low moisture values in the Hackberry-Box
; Elder, Hackberry, and Sumac communities of the peninsula area shows that there is no correlation between marsh water levels and moisture values at the 10, 20, and 50 cm. depths.
I Soil Chemical Analyses Soil samples were collected for summer from each of the five
. monitoring locations on the Davis-Desse property and from the two
( sites at the Ottawa control area at the 10, 20, and 50 cm. depths. 2

Due to an oversight, fall soil samplos were collected only from the Tower Woods at the specified depths. Samples for the peninsula sites i and for the Ottawa sites were not collected in the fall. All samples were analyzed as described in earlier reports. Results of these analyses are summarized in Table B-4. In the peninsula area the soils of all three sample sites show
- the youngness of the beach deposit environment. The cation exchange complex is saturated with bases as indicated by the 100 percent base saturation at all three depths at all three sites. Cation exchange capacity (C.E.C.) is lowest in the sumac community as in previous years. The relatively low C.E.C. with a concentration of higher levels near the surface indicates a continued accumulation of organic matter which contributes most of the exchange sites. The Ilackberry-Box Elder II community has a somewhat higher C.E.C. ; more organic matter is in-corporated to a greater depth in the profile of these young soils.
The highest C.E.C. levels are found in the Hackberry-Box Elder I community which has consistently shown evidence of more maturity in the soil profile during the 5-year reporting period. The pattern of C.E.C. values is similar to past years. Organic matter in the soils of the peninsula area in 1978 has a similar pattern to previous years with concentration near the , surface of each of the soil profiles. The depth of organic matter concentration increases from the least mature sumac community to the mature Itackberry-Box Elder I community, and total organic matter increased from the least mature to most mature community. Organic matter levels continue to coincide with C.E.C. levels in each of the peninsula soils and contribute substantially to these C.E.C. levels. The pH values also continue in the neutral to slightly alkaline i
, s , ._. - ,
f range as in previous years for the peninsula sites. These neutral to alkaline pH values further demonstrate the youngness of these sites and coincide with the high percent base saturation levels. The levels of sulfates (ppm) continue to be very low in the peninsula area. Decreases were experienced at all three depths at all three sites from fall 1977 to summer 1978. Such changes in sulfate levels are not uncommon in young soils; in the penin-sula area, the decrease in~ sulfate concentration has been accom-i panied oy other changes in the soil chemistry over the 5-year reporting period. It remains to be seen if such changes are cyclical, if they are a sign of maturing of the peninsula soils, or if other factors are contributing to the changes. A noticeable pattern in the chemical analyses of the soils of the peninsula area has been tne seasonal changes in parts per i million (ppm) of calcium, magnesium, and potassium over the report-
, ing period of five years. We now have data for four pairs of summer /
fall changes to compare. From summer to fall 1974 and summer to fall 1976, ppm of calcium increased at all three soil depths monitored. In l'975 ppm of calcium decreased at the 10 and 20 cm. depths, but increased at the 50 cm. depth. Moisture seems to be the most in-
, portant related factor because 1974 and 1976 were dry and moderately dry, respectively. 1975 was a moderately moist year with a surplus of precipitation over actual evaporation. In the wettest year of the reporting period, 1977, ppm calcium decreased.at all three oil depths monitored. An important aspect of the decline in ppm calcium
( in 1977 was the levels of calcium in the fall of l'377 compared to the 5-year average values: 10 cm. - 1700 ppm compared to 2315 ppm average; 20. cm. - 1400 ppm compared to 1748 ppm average; and 50 cm. -
f 1100 ppm compared to 1211 ppm average. The greatest decrease is near the surface, a response to dissolving calcium in the increased water falling on and moving through the soil profile. The changes in ppm magnesium from summer to fall do not follow the same pattern as calcium in the peninsula area. The changes from summer to fall 1974 and summer to fall 1975 are increases in ppm mag-nesium. The changes' from summer to fall 1976 and summer to fall 1977 are decreases in ppm magnesium. These changes seem to be a factor of substitution in the exchange complex as potassium replaces magnesium. Such a relationship seems to be valid because the summer to fall change in 1975 was a decrease in ppm potassium when ppm magnesium increased and increases in ppm potassium from summer to fall 1976 and summer to fall 1977 when ppm magnesium decreased. An important aspect of the changes in the ppm magnesium and potassium was that magnesium levels were near the 5-year average and potassium levels were above the 5-year average: 10 cm.-magnesium 200 ppm compared to 224 ppm average; 20 cm.-magnesium 160 ppm compared to 157 ppm average: 50 cm.-magnesium 100 ppm compared to 79 ppm average; 10 cm.- potassium 50 ppm compared to 37 ppm average: 20 cm. potassium 40 ppm compared to 23 ppm average; and 50 cm.-pot-assium 20 ppm compared to 15 ppm average. Perhaps even more important has been the continued decrease in ppm of calcium and magnesium, and a renewed decrease in ppm potassium from fall 1977 to summer 1978. The fall of 1977 and spring of 1978 were wett the added moisture may have dissolved and removed these soluble bases. However, percent base saturation has not decreased along with decreases in ppm of bases. The ef fects of the decrease". must wait for anaiyses in 1979. ( 4
4 In the Tower Woods the soils of both sample sites deconstrate the stability of the more mature environment compared to the pen-insula area. The relatively high cation exchange capacity is the result of the greater clay-humus complex in the Tower Woods' soils. The cation exchange capacity decreased somewhat from fall 1977 to summer 1978, but the change was within the range of changes that a has occurred from season to season in past reporting years. While the cation exchange capacity decreased from fall 1977 to summer 1978, the percent base saturation remained high with saturation at 100 percent in the summer of 1978. Base saturation increased from d summer 1977 to summer 1978 at the same time that ppm of the bases decreased. Such a contrast in changes cannot be explained usir.g the data available. Organic matter in the soils of the Tower Woods is well distri-buted through the upper part of the soil profiles in well-defined A horizons. The organic matter contributes to the high C.E.C. in tne Tower Woods' soils. The level of organic matter decreased in summer and fall 1978 from summer and fall 1977, but the decrease is within the range of changes experienced in previous years of the reporting period. The soils of the Tower Woods have remained nearly neutral or slightly acidic through the reporting period. The pH values in 1978 were nearly the same as pli values for 1977 with the exception of an increase in pli at the 50 cm. depth in the Toledo soil from summer 1977 to summer 1978. The increase in pH coincided with an increase in base saturation and a decrease in cation exchange capacity. (
The levels of sulfates (ppm) continue to be low in the Tower Woods. In summer 1978, increases in ppm of sulfates occurred at the 20 and 50 cm. depths in the Fulton soil and decreases in ppm of sulfates occurred at the 10 and 20 cm. depths in the Toledo soil. However, sulfate levels at all soil depths in both Fulton and Toledo soils increased fron summer, 1978, to fall, 1978. While changes have occurred from season to season and from year to year over the 5-year data period, the changes have been relatively small and cannot be attributed to enanges in other soil or related factors. A noticeable pattern in the chemical analyses of the soils of the Tower Woods has been the seasonal changes in parts por million (ppm) of calcium, magnesium, and potassium over the 5-year reporting pe riod. A comparison can be made among four pairs of summer / fall changes. The ppm of calcium increased from summer to fall at all three depths monitored in 1974, 1975, and 1976. These three years can be considered dry to moderately dry with respect to the precipi-tation - actual evaporation balance in the Tower Woods. In contrast, the ppm calcium decreased at all three depths from summer to fall 1977. In terms of moisture balance, 1977 can be considered a moist year in the Tower Woods. An important aspect in the decrease in ppm calcium in 1977 was the icvels of calcium in fall 1977 compared to the 5-year average levels: 10 cm. - 4000 ppm calcium compared to 4458 ppm averager 20 cm. - 3900 ppm calcium compared to 4034 ppm average; and 50 cm. - 3400 ppm calcium compared to 3668 ppm aver- ; l age. The decline relative to the average was greatest in the 10 cm. I e depth, indicating an increased leaching from the surface downward.
' Perhaps even more important was the decline in ppm calcium from fall 1977 to summer 1978.
The decreased' ppm calcium was not accompanied
i
/
by a decrease in base saturation. j The changes in ppm magnesium from summer to fall follow a pattern similar to the changes in the ppm calcium except for 1974. In 1974, the ppm magnesium increased at 10 cm. but decreased at 20 and 50 cm. , The decrease at the lower depths can be attributed to substitution of calcium and potassium for magnesium in the cation exchange complex. In 1975 and 1976 the ppm magnesium increased from summer to fall. lioisture and cation substitution both contribute to these changes. The increases in 1975 and 1976 are related to the moderately dry conditions in the Tower Woods and the renewed leaf supply in the fall whien released bases into the soil complex. In 1977 the moist condi-tions helped to reduce the ppm magnesium. The substitution of pot-
, assium for magnesium in 1977 also helped to explain the change in ppm magnesium. - Potassium substitution seems to be a regular feature of the summer to fall changes in the Tower Woods. Each year from 1974 through 1978 there has been a summer to fall increase in ppm pot-assium at all three depths monitored. The one exception was a de-crease in ppm potassium at the 10 cm. depth in 1975. An important
,. aspect of the changes in ppm magnesium and potassium was that nagne-sium levels declined below the 5-year averages, whereas potassium levels increased to be near or above the 5-year averages: 10 cm. - magnesium 450 ppm compared to 532 ppm average 20 cm. - magnesium 1 450 ppm compared to 493 ppm average: 50 cm. - magnesium 430 ppm-corapared to 532 ppm average; 10 cm. potassium 210 ppm compared to 215 ppm average: 20 cm. - potassium 180 ppm compared to 160 ppm
, average; and 50 cm. - potassium 180 ppm compared to 136 ppm average.
( 4 --s- -- m * - - e-u=q-- +y
Perhaps even more important has been a continued decrease in ppm calcium and magnesium and a renewed (but relatively small) decrease in potassium from fall 1977 to summer 1978. Fall 1977 and spring and early summer 1978 were moist the added moisture may have con-tributed to increased solubility of bases and their removal from the soil profile. A comparison was made between the analyses of the circulating water from the cooling tower for 1978 and soil analyses for the Fulton soil of the Tower Woods for 1978 and average analyses values for the 5-year reporting period (Table B-5) . High and low values of calcium and magnesium in the circulating water did not correspond to higher or lower values in the Fulton soil for summer or fall. In other words,
, the circulating water appears to have little or no effect on the levels
( of calcium and magnesium in the Fulton soil of the Tower Woods. Summer and fall values for calcium in the soil are lower than the 5-year aver-age. Magnesium values for fall are somewhat above the 5-year average in the soil and contribute to a greater percentage of the soil carbon-ates. However, the circulating water does not appear to have an effect on this change because the percentage of magnesium carbonates in the circulating water is similar to the 5-year average soil percentage. Sodium values incre ased sharply from summer to fall at the 10 cm. l depth in the Fulton soil of the Tower Woods (Table B-6) . Values at the 20 and 50 cm. depths more closely approached the 5-year average, whereas the value at 10 cm. was more than three times the average.
' Sodium concentrations in the circulating water ranged from 7.2 ppm to i 30.5 ppm but did not increase toward the fall. It is possible that:
- 1) sodium fall-out from the cooling tower may be producing a cumula .
e-..
tivo offect on the soil; 2) a drier fall has concentrated sodium near the soil surface due to evaporation; and/or 3) the fall value for sodium is an " abnormal" reading and will rectify itself by the spring or summer of 1979. The sodium level needs to be watched carefully and soil ana-lyses in 1979 will help to indicate if a new trend is emerging. Some General Trends Data from all five reporting years have been summarized in graphic form for the sumac community of the peninsula and the Fulton soil area of the Tower Woods (Figures B-4 to B-2 3) . In looking at these graphs, some general trends can be seen which demonstrate the natural seasonal cycles or ongoing changes which can be expected in the two monitored areas, the Tower Woods and the peninsula area. Organic matter in the soils of the peninsula area remains rela-tively low and concentrated near the surface. In drier years, it appears that there is a trend to increased organic matter from summer to fall (Figure B-4). Cation exchange capacity is closely related to organic matter content of the peninsula soils because of the low clay content in this area. Cation exchange capacity fluctuates from
' season to season and year to year in response to changes in organic matter. Noticeable increases in C.E.C. in fall 1974 and fall 1976 coincide with the largest increases in organic matter (Figure B-5).
Changes in C.E.C. are mostly restricted to the 10 and 20 cm. depths where organic matter is concentrated. Base saturation remains high
-(near 100%) at all three depths monitored (Figure B-6,7,8) . Potassium contributes a small but consistent percentage of the cation exchange.
Calcium and magnesium vary inversely in their contributions to the cation exchange. Calcium contributes between 85 and 95% and magnesium
=-- -,
contributes between 6 and 13%. Moisture has proven to be one of the most important, if not THE most important, variables in.the peninsula area (Figure B-4). Spring, summer, and fall moisture conditions can be critical to plant growth, seed germination, and even plant community composi-tion (see section A) . Important variations in the timing of dry and wet periods have been a part of the moisture factor. The summers of 1974, 1976, and 1978 and spring 1977 were relatively dry. Unlike these seasons, spring 1975, fall 1975, spring 1976, summer 1977, and fall 1977 were all very moist. Perhaps the most critical and influential aspect of moisture in the peninsula area has been the lack of a completely dry period when there was near "0" moisture available. In contrast, the Tower Woods has suffered several very dry periods over the reporting years. The amount of organic matter in the Fulton soil of the Tower Woods is greater than in the sumac community of the peninsula area. Changes in organic matter levels have generally been restricted to the 10 and 20 cm. depths with summer to fall decreases in 1974, 1975, and 1978 and summer to fall increases in 1976 and 1977 (Figure B-9). The increases in organic matter content froa summer to fall in 1976 and 1977 were accompanied by increases in cation exchange capacity. These parallel changes indicate organic matter is at least partially res-i ponsible for the cation exchange capacity of the Fulton soil. However, I decreases in organic matter content from summer 1974 to fall 1974 to winter 1975, from summer to fall 1975, and from summer 1978 to fall 1978 were accompanied by increases in cation exchange capacity. These
'(-
opposed changes indicate clay also is at least partially responsible for the cation exchange capacity of the Fulton soil.
r The percent base saturation. at the 10 cm. depth in the Fulton soil of the Tower Woods decreased sharply from fall 1975 to summer 1976 (Figure B-10) . The decrease was accompanied by an equally sharp decrease in the percent calcium in the exchange complex. From summer to fall 1976 and from summer to fall 1977 important increases in percent base saturation and percent calcium saturation occurred. At the 20 cm. depth summer declines in percent base saturation and in percent calcium saturation have occurred in each of the reporting years from 1974 through 1977 (Figure B-ll) . In each of the corres-ponding fall seasons, both total base percent and calcium percent saturation increased. The same pattern of summer decrease and fall increase occurred at the 50 cm. depth in 1975 and 1977 (Figure B-12). ( Moisture appears to be a critical factor in the Tower Woods. The nature of the clay rich Fulton and Toledo soils in the woods means very wet and very dry periods can and have been observed (Figure B-13) . Variations from season to season are common as well as from year to P year. Even strong contrasts in moisture can be seen from depth to depth as the fine textured clays recharge moisture supplies or dry more slowly than the sandy soils of the peninsula area. The sumner and fall of 1974, summer 1975, summer 1976, and fall 1978 were i noticeable dry periods at all three monitored soil depths. The fall 1975 at 50 cm. .and the spring 1977 at 10 cm. were also drier than average for these particular seasons. Spring 1975, spring 197G, fall 1976, summer 1977, fall 1977 and spring 1978 were notice-able moist to wet periods over the reporting years. Most important { are the' extreme. seasonal differences in moisture in the Tower Woods, unlike .the more moderate seasonal changes in the peninsula area (Figures B-13 and B-4).

r ANNUAL REPCRT DAVIS-BESSE TERRESTRIAL MONITORING cot 1 TRACT JANUARY, 1979. C. Terrestrial Animals S.H. Vessey Department of Biological Sciences d This year approximately equal efforts were utilized in sampling the peninsula study area at Davis-Besse and the Ottawa Wildlife Refuge refer-ence site. As in the past, qualitative data were collected on amphibians, reptiles, and large mammals, with indicators of abundance, while quantita-tive population estimates were obtained for birds and small mammals. Such an approach seems the most efficient way to detect any major shif ts in habitat utilization as a result of site operations. Water, alone or in conjunction with temperature, of ten is the most important physical factor affecting the ecology of terrestrial organisms (Krebs, 1978). The problems that animals face with respect to water bal-ance differ sdbstantially from those of plants, because animals are mobile i and can escape from many moisture problems by selecting the proper habitat. Most of the research on terrestrial animals dealing with moisture concerns adaptations for water conservation in desert forms, such as camels and kangaroo rats. Data on moisture tolerances for the terrestrial vertebrate species found in N. U. Chio are lacking. We can assure that, because precipitation generally exceeds evaporation, lack of moisture is not . likely to directly influence distribution and abundance. Possible exceptions are flooding, perhaps due to marsh management, and summer
C-2
.f drought.
Amphibians and Reptiles The main source of data for herptiles comes from logs kept by B.G.S.U. personnel in the field. The species and the indicators of abundance re-ported have remained similar over the past few years, suggesting rather stable conditions. The dense woo'ds at Ottawa, compared with the more diverse area being sampled at Davis-Besse, may account for the paucity of herptiles found at Ottawa. Eastern garter and northern water snakes continue to be the most abundant at Davis-Besse, while painted turtles were common along the edge of the Ottawa reference woods (Table C-1) . Winter Birds Davis-Besse: Most of the winter birds observed during the peninsula study area circuit were transient shore birds and ducks, the latter taking advantage of several open water holes. One of these holes was from warm-water' discharge; several other generating sites in the Toledo area also have large numbers of waterfowl around discharge areas. The resident pop-ulation has remained reasonably constant since 1974, with between 34 and 104 individuals seen; species density ranged from 10 - 16 (Tables C-2 and C-6). Species density is about one-half to one quarter of that in the sum-mer, with counts of individuals as little as 6% of summer numbers in 1978. I l l 1 L _ )
. C-3 Although the fall and winter of 1976-77 were unusually cold and snow cover in 1977-78 unusually heavy, fluctuations in numbers seen were within the range of other years.
Ottawa: Sightings at Ottawa were complicated somewhat this year by the presence of a large flock of tree sparrows, estimated at 250, on 12 l February (Table C-3) . Although flocks this large are not an unusual sight in the winter, it is not clear whether they were residing on the site. Large numbers of transient waterfowl, not feeding in the terrestrial com-munity, were recorded earlier, on 7 January. Seven of the nine resident species also were seen at the Davis-Besse site. Not counting the tree sparrow flock, the two areas were quite similar in terms of numbers and diversity of winter residents. Spring and Summer Birds Davis-Besse: A decrease of seven species was noted this year at the Davis-Besse site, down from 42 to 35; but an increase of 60 individuals was noted, resulting in the rather low species diversity index of 2.79
$ (Table C-4). The increase in numbers was entirely due to red-winged blackbirds, from about 200 last year to 300 this year. Because of the large numbers of these birds, our counts are less precise than for other l f
- ' species. Resident birds seen last year but not seen this year include red-I tailed hawk, sparrow hawk, , red-headed woodpecker, least flycatcher, wood pewee, tufted titmouse, cedar waxwing, red-eyed vireo, warbling vireo, pro-thontary warbler, and brown-headed cowbird. Black duck, downy woodpecker, barn swallow, blue jay, brown thrasher were present this year but were not seen last year. Thus, the changes in species density occur across a variety of taxa, and none of these species was represented by more than two pairs in a year. Some, such as the downy woodpecker, were probably present in
C-4
/
1977, but not seen. Ottawa: The Ottawa site underwent an even greater reduction in both numbers of species and numbers of individuals, from 40 species to 27, and 372 individuals to 192 (Table C-5). Much of the decline in individuals was due to a reduction of mallards from about 100 in 1977 to only 10 in 1978, and a decline of grackles from 30 to 8. In spite of these large changes, species diversity was essentially unchanged; the smaller number of indivi-duals and species in 1978 was compensated for by a more even distribution of numbers across those species. Those species absent in 1978, but present the year before, cut across all taxa, with three species of sparrows and two species of flycatchers missing. The blue jay and brown-headed cowbird, both seen in all past years, were missing from both sites this year. Blue jay populations fluctuate widely in the northeast, in some years due to disease outbreaks. The year-to-year turnover within each site was of the same order of 1 magnitude as the between-site turnover. In 1978, 13 resident species were seen at Davis-Besse that were not seen at Ottawa, and seven were seen at Ottawa that were not seen at Davis-Besse; this was not greatly different from previous years. In contrasting winter and summer resident populations at both sites, percentage-wise there continues to be a greater year-to-year fluctuation in winter populations than summer (Table C-6) . Diversity indices, with the exception of Winter,1978 at Ottawa, have changed as much in summer as in winte r. The use of species diversity indices is attractive because it becomes possible to evaluate and compare communities by inspecting a few numbers i rather than considering each species present. With respect to birds, we l l \ l l L
C-5 know that species diversity is correlated with diversity of foliage height, or structural diversity, rather than plant species diversity (MacArthur and MacArthur, 1961). Changes in the environment which reduce the amount of structure, or layering, in the forest will cause a decrease in bird species diversity. This relationship only holds for resident, breeding birds; thus we have not considered migrants or transient feeders in our analyses. Small Mammal Populations
. By means of live-trapping grids at Ottawa Wildlife Refuge, Davis-Besse site, and Carter Woods, spring and fall estimates were made by mark-and-recapture method using Sherman traps. A mixture of rolled cats and peanut butter was used as bait, and cotton nestlets were provided to reduce trap mortality. The only small mammal caught in the last five years at Davis-Besse.has been the white-footed mouse (Peromyscus leucopus) . Since all grids are in wooded areas, the absence of other species is not surprising; however, the short-tailed shrew (Blarina brevicauda), common in wooded areas in northwest Ohio, is present in large numbers at Carter Woods but has never been caught at the other two study areas.
Capture data are summarized in tables C-7 through C-10. This year's spring population at Davis-Besse was extremely low, and no Lincoln-Peterson estimate could be calculated. Only two individuals were caught a to.tal of six times in 240 trap nights. A much higher pop-ulation was present at Ottawa, with 17 individuals caught 28 times in 200 trap nights. By fall the Davis-Besse population was still very low, with five individuals being caught seven times in 240 trap nights. At Ottawa the fall population had decreased substantially, with five different indi-viduals being caught nine times, in 200 trap nights. With five years of data at Davis-Besse and Carter Woods, we now have some idea about the range of variability in numbers we can expect to en-
C-6 counter from year to year. During the spring, Davis-Desse estimates have ranged from 2 to 28 mico per hectare, while Carter Woods has had a similar f range, 7 to 27 (Table C-ll) . Fall populations are much more variable, ranging from 11 to 211 at Davis-Besse 'and 16 to 63 at Carter Woods. Spring populations are low and, to some extent, predict the size of the fall peak (Table C-ll) . An exception is 1977, where the population at Davis-Besse increased from 11 to 211, the highest ever recorded there. (That peak estimate , however, had a very high standard error because so few marked mice were recaptured.) There is little indication of correlations among sites between V igh years and low years. At Davis-Besse 1974 and 1978 were low years, but not so at Carter Woods, where 1975 was a low year. An unusual pattern occurred at Ottawa in both 1977 and 1978, where numbers declined from spring to fall. We have noticed at Carter Woods, where trapping is conducted continuously from March through November, that in sone years the population peaks in August, declining precipitously during the fall, although still remaining above spring levels. Because of the large yearly fluctuations in numbers of white-footed mice, we will need to document changes persisting for several years before we can attribute them to long-term changes in food supply or habitat quality. P. leucopus is the only terrestrial mammal at the site that is easily cap-tured and that can be censused reliably. Medium-Sized Mammals A relatively small effort was made this year to mark and release rac-coons and opossums. The trapping effort in 1978 differed specifically from the previous years in that traps were set within the small-mammal grids and run in conjunction with them during the fall only; previously, the entire peninsula has been trapped at Davis-Besse and the entire woods at Ottawa. One raccoon was caught in 48 trap nights at Davis-Besse, and three were captured at Ottawa in 34 trap nights. These results are consistent with last year's more extensive trapping in that raccoons were more abundant at Ottawa than
C-7 r at Davis-Besse in both years. Even with the small effort this year, some opossums might have been expected at Davis-Besse. However, opossum numbers were unusually low this year, based on extensive trapping in Wood County and reports from game protectors. Severe winters can be expected to reduce numbers of this predominantly southern species. Miscellaneous observations of other mammals revealed no substantial changes from previous years. Rabbits were seen in low numbers at Ottawa, not having been reported from there last year. The resident deer popula-tion ac Davis-Besse has remained stable for five years. Similar numbers reside at Ottawa, in both cases a single buck with three or four does. Bats A red bat (Lasiurus borealis) was found dead at the cooling tower dur-ing the monitoring of fall bird migrations. Conclusions
~
We now have five years of data from the Davis-Besse site, with quanti-fied results principally for birds and small mammals. The Ottawa National Wildlife Refuge reference area, with two years of data, is similar to Davis-Besse with respect to these fauna. Thus, within-year fluctuations between the sites seem to be no greater than between-year changes within sites. The resident breeding bird populations are most easily and most accu-rately censused. There are about 40 such species, and the ecological tol-erances are well-described for many of them. Thus birds would seem to be the ideal vertebrate group to use for assessing environmental impact. -Un-fortunately, nearly all of these species migrate to places where they are subjected to physical, chemical, and biotic influences that have nothing to do with conditions on the breeding ground. The reference area controls l' ! for some of these variables. Thus, blue jays and cowbirds disappeared from both sites this year; either the same forces were operating at both sites i
C-8
/
to eliminate them, or some off-site change is affecting the migrant part of the population. At least we are reasonably sure that the changes are not site-specific. References Krebs, C.J. 1978.

ANNUAL REPORT DAVIS-BESSE TERRESTRIAL MONITORING CONTRACT < JANUARY 1979 D. Atmospheric Environment Glen R. Frey
- Department of Geography Introduction The network of climatological stations monitoring the atmospheric environ-ment near the Davis-Besse Nuclear Power Plant has been in operation since April 1974 with no significant problems. The format and procedures for the systematic observations were originally outlined in Section D, Semi-Annual Report, June 1974.
Most of the observations recorded this year can be included in the operational data base even through the plant was not in continuous operation for the year. The vapor plume generated by the cooling tower can change certain atmospheric conditions at a given instant. Within a radius of 1,000 feet, the tower mist can add to the precipitation totals. If the vapor plume comes in contact with the ground, relative humidities and dew points are increased. A temperature decrease of nine degrees was observed when the plume shaded a station under strong insolation conditions in early spring. Similarly, the plume could blanket an area at night under negative net energy flux and cause temperatures to be warmer than expected. Any of these changes individually or in combination will change the amount of evaporation. The frequency of this occurrence is not large with a tall cooling tower and variable wind patterns such as that at Davis-Besse. In addition, climatological averaging masks these fluctuations so that any impact would not be obvious. If any significant atmospheric environmental changes did occur they would be revealed as long-term changes in the relationships between stations in the immediate surrounding region. Purpose The purpose of this study is to isolate and identify the basic variation patterns for and between stations. These variability patterns are the key to any
D-2 1 possible environmentally induced changes. r Instruments and Measurements Climatological stations are maintained at three primary locations on the Davis-Besse site. Station "T" is the base station at the microwave /meteorolog-ical tower and is set up according to weather service standards. It is located in a fenced in area on a grass surface. Because of the great distance from any trees or other obstructions and very level terrain, advection processes are at a maximum. Station "A" is in the cooling tower woods and highly influenced by a continuous and complete forest canopy. The fairly close proximity to open water and generally open nature of the woods all influence climatological measurements. Station "B" is located in the woods on the sandy soil of a former beach ridge. The station, in a clearing, does not have a forest canopy but instead is surrounded by dense growth that limits advection. The sandy soil, which dries very rapidly, coupled with an almost complete lack of wind currents results in different climatic characteristics. Four supplemental locations on the Davis-Besse site are set up with non-recording rain gauges and read weekly to provide additional data on rainfall patterns. Station "0W" is the basic off-site reference station located in the Ottawa National Wildlife Refuge. This location was chosen because of its similar vegetative cover, proximity to Lake Erie, and upwind position (in terms of climatic normals). This station has a setting very similar to Station "A", on a margin of swamp area in a woods with complete canopy cover. Because of the greater extent and density of the woods it is less influenced by the wind. Station "BC", the inland reference station, at Bowling Green State University is slightly influenced by proximity to buildings. Instrumentation in the climate shelters records data continuously on paper strip charts. From this, the information is summarized by day, week, month, and reporting period. Each period is analyzed slightly differently to
D-3 stress interstation fluctuations. Recording evapometers were reinstalled according to schedule at the end of April. Evaporation amounts were obtained until the end of October. All hygrothermographs were brought in during the month of June for a cleaning and calibration check. No data vere lost because the back-up hygrothermograph was rotated between sites. For the remainder of the period calibration of the hygrothermographs was verified by using the Assman Psychro-meter and by rotating the back-up unit between sites. Evaporation instrumenta-tion was calibrated primarily by rotating the back-up evspometer between sites. Soil temperatures were checked by portable soil thermometers. Some problems were encountered in maintaining calibration. In particular the "0W" soil thermograph constantly reads low, requiring some data interpolation. Since the sensing elements and timing mechanisms are exposed to the fluctuations of weather they deteriorate causing neasurements to drif t, resulting in a loss of accuracy. Up to this point the data obtained still represent true conditions because frequent calibration checks are being made. The biggest difficulty is that more and more effort must be made in checking calibration and making adjustments. Replacement of some of these parts should be done before an inordinate amount of time has to be spent in checking and testing. Presentation of Data The data reviewed in this report are based primarily on the weekly periods January 6, 1978, through December 22, 1978. Files are maintained and analyzed by day, week, and month. In addition, graphic displays are completed by week and month for summarized normals, standard deviations, departures from average and deviations from Station "T". Data are presented in two basic parts for this report. Part I: Figures D-1 through D-12 are monthly summaries of normals and variations of the elements. Figures D-13 through D-24 are discriminant function coefficients. Part II: Figures D-25 through D-32 represent weekly
D-4 interstation deviations with fluctuations being graphed about the values for the base Station "T". Interpretation of Data ENTIRE PERIOD. Throughout 1978 extremes in temperature were the distinguish-ing feature. The frigid cold of January and February was in sharp contrast to very warm readings in August and September. March and April were very cool, averaging well below normal. The cold spring retarded vegetation growth at least two weeks behind what would be considered normal'for the region. Precipitation was below normal for the year in spite of the blizzard which . resulted in high values for the month of January. July, the only other month that had significantly high rainfall totals, also had a highly variable spatial pattern. Even including the climatological extremes, the patterns of fluctuation were similar to previous years. The complete set of' graphs (Figures D-25 through D-32) illustrates the basic shift between rinter and summer inter-station variability. The typical interstation fluctuation is small in winter and is considerable in the warmer part of the year. The months of January through May had relatively small fluctuations. June had an abrupt shift to a high degree of interstation differences which continued through October. This shift in the interstation fluctuation occurred one month later than in previous years. This is for both summer and winter. In November and December there was no gradual change to the typical winter pattern exhibited in previous years but rather a constant intermediate level. This is attributed to the relatively mild conditions of those months. Maximum temperature departures from base Station "T" are typical of shifts that occur from one season to another (Figure D-25). In the first third of the year, interstation fluctuations were small. Throughout the summer portion both "BG" and "B" were warmer than Station "T". The University site was the warmest because of the distance from water, with "B" slightly warmer because of sandy soils and greatly reduced advection. Stations "OU" and "A" were cooler because
D-S of.the vegetation' canopy. Conditions were more similar in the fall of the year however the stations exhibited a larger fluctuation pattern than would be expected for that time of the year. Minimum temperatures, in terms of departures from Station "T", are an excellent example of the changes that occurred throughout this reporting interval (Figure D-26). During January and February all station fluctuations were similar to Station "T". Most averaged warmer while Station "0W" was
;
slightly cooler. During the summer portion "BG", because of its inland location, and "B" with reduced advection were warmer than the reference Station "T" while all the other stations influenced by woods were considerably cooler. In the last half of the year the woods stations gained relative to "T". This general shift in position between coastal and inland stations is the same as in previous years. However the variation between stations was larger than in the past. Average temperature departures from Station "T" are a composite of conditions described under maximum and minimum temperatures (Figure D-27). Most of the year interstation fluctuations were relatively small. There was a general shift of positions with respect to the base station. During the first part of the year most stations were slightly warmer while later most were cooler than "T". The Station "BG" was constantly warmer; "B" was slightly cooler, with "A" and "0W" distinctly cooler for the period which maintained the established pattern. During November and December most stations were cooler than i
"T" which was unusual. .
Temperature range had the same basic pattern throughout the course of the year as in previous years (Figure D-28). The greatest departures cere during the warmer periods. In the cooler months, the range of temperatures was very similar. Throughout the year "BG" and "B" had greater ranges than "T", with l "A" and "0W" smaller. Evaporation departures from Station "T" again are dependent upon the basic seasonal fluctuations (Figure D-29). The evaporation meters are in operation I
D-6 only during the warmer months of the year since they use distilled water and could easily be damaged. Most stations had values less than "T". It is . expected that most stations would be less since "T" is the most exposed to wind currents. Station "BG" had higher values reflecting the warmer ccnditions. Precipitation had several distinct periods of high variability. During the summer this was due to convectional storms passing over some stations and not others (Figure D-30) . The higher fluctuations in the first half of the year cannot be explained in this manner since precipitation in each instance was wide-spread. High winds during snow storms resulted in poor sets of 4 readings. Humidity is given both in the terms of relative humidity (Figure D-31) and dew point (Figure D-32). Generally there was a high degree of week-to-week fluctuation. Many factors affected the humidity, including evaporation, proximity to water, wind currents, and vegetation growth. Since the degree of interstation' variability was relatively constant throughout the period, no specific sections need further discussion. JANUARY. It was one of the coldest months in the history of climatological records in northwest Ohio. In addition to the colder than normal temperatures there was the blizzard with record-breaking snowfalls. Despite the record cold, all monthly temperature characteristics between stations were j quite similar (Figures D-1 and D-13). The greatest differences according to the discriminant function coefficients were in total precipitation and minimum temperature. The largest interstation variations were between "A" "T" and "A" "0W". This is obvious when looking at total precipitation between stations. The actual amounts may not have been accurately recorded because there was great difficulty in getting measurements during blizzard conditions.
FEBRUARY. This month exhibited great variability in temperatures with record lows in the first part and mild temperatures during the last. Conditions were relatively similar amongst most stations. Station "BG" was slightly
D-7 warmer than the others (Figures D-2 and D-14). The greatest discrepancies between stations were between "A" "0W" and "T" "BG". In these instances, the greatest monthly interstation variability was total precipitation and average air temperature. MARCH. Much cooler than normal and relatively dry is the best description of the weather in March. The temperature averaged 5 0F cooler than the long-term statistical average. All stations showed this trend. "BG" was slightly warmer because of its inland location (Figures D-3 and D-15). The greatest interstation, differences were between "T" "BG" based on variations in average air temperatures. APRIL. Cool temperatures were the key distinguishing factor of the month. Overall, there was minimum interstation fluctuation (Figures D-4 and D-16). No one element was o'tstanding, u however, maximum temperature and precipitation made "BG" different from other stations. MAY. There was a sharp break from previous conditions (Figures D-5 and D-17). High temperatures and lack of rainfall were characteristic. Differences between stations were not large compared to previous years. "A" "B" and "T" - "B" had the greatest differences. JUNE. Temperatures and precipitation were normal for the month (Figures D-6 and D-18). Most elements had a degree of variability so that there was considerable difference between stations. Highest overall Dsq values were between "BG" and all other stations. Although all elements contributed to this fluctuation the most important were average air temperature and evaporation. JULY. Precipitation was below normal. There was considerable variation between stations "B" "BG" and "T " "BG". Precipitation was the key factor leading to the ditiurences. Temperatures throughout the region were similar and normal (Figures D-7 and D-19).
D-8 AUGUST. Rainfall for the month was below normal and highly variable between stations. Overall, August had the greatest amount of interstation variability of any month over the last two years (Figures D-8 and D-20). The greatest combined differences occurred between Stations "A" "BG" and "A" - "B". The specific elements that led to these differences were maximum temperature, evaporation, and total precipitation. SEPTEMBER. Precipitation was below average while temperatures for September were above (Figures D-9 and D-21). Variability was less than August with Stations "T" "BG" having the most significant differences. The specific elements that ranked highest were evaporation and precipitation. OCTOBER. The month was cool and dry. Precipitation was below normal at all stations (Figures D-10 and D-22). Bowling Green was again the warmest station but the dif ferences between locations were smaller than the preceding summer conths. The fluctuation patterns that gradually shift from highly variable to more similar conditions did not. Greatest differences were between Station "B" and all others. Evaporation and precipitation were the principal elements causing the variability. NOVEMBER. Above normal temperatures and average precipitation were characteristic (Figures D-ll and D-23). Station "BG" still ranked the warmest but overall differences were smaller. The Dsq ranking had the most significant fluctuations between Stations "B" "BG" and "T" "BG". Maximum temperature and temperature range were the most important elements leading to that difference. DECEMBER. Temperatures were colder than normal with precipitation slightly below average (Figures D-12 and D-24). Most elements were more similar in their fluctuation patterns as they were in November, but not yet as low as previous years. The interstation variability was greatest between "A" "B" and "B" "BG". Precipitation was again the leading element in determining the variations.
D-9 Conclusion No significant statistical differences were found between the atmospheric conditions during pre- and post-operational phases near the Davis-Besse site. Therefore, no short-term effects have been determined. 4 4 0
