7egetation in the vicinity of the LaSalle County Generating Station was surveyed for damage caused by rise ice deposition during the winter of 1984-85 This survey was done in accordance with section 4-2-2(d) of the LaSalle County Station Dtvironmental Protection Plan on the 15th of May, 1985 with the assistance of Mr. B.B. Barriskaan of the Commonwealth Edison Company and is the second survey of this site done by Barry J. Jacobsen, Ph.D.

Summaries of the 4th quarter of 1984 and lat quarter of 1985 of the Fog and Rime Ice Monitoring Program for the LcSalle Station were utilised to identify areas of most likely damage. The survey area is shown in Figure 1 (attached). Also shown in this

' figure are specifie sites sentioned in this report. The survey area was sufficiently large so that similar plants could be observed in areas reported to be with and without rise ice.

Site #1 located around the cooling water discharge was the l site where rise ice was reported acet frequently during January j of 1985 Cottonwood, willow, autumn olive and sweet olover observed at this site did not show evidence of lee damage. 1 j

However, willows located north of the cooling water disoharge did '

show more winter injury and sanker disease (Venturia and cytospora) than other willows in the survey area. Winter injury was dias * -

l nosed based on tip diebeek and one sided osabium noorosis and bud death. This winter injury is thought to be due to the vara discharge water delaying the vernalisation process. This delay

• i in vernalisation does not allow the plant tissues to harden off

! enough to prevent freezing injury when extreme cold occurs. The winter injury noted was relatively stnor in nature. Willows growing 25-50 yards north of the cooling wazar disonarse also had wood borer damage.

Autumn olive plantings in this area also displayed. some dieteck.

However, the distribution and type of dieback is suggestive of prob-less relating to transplanting and plant establishment.

Sweet olover growing in this area showed no evidense of seethering such as would be expeeted from ice damage.

Site #2 located to the west of the ecoling water discharge had apple and oak. trees.uhich showed winter damage. This damage.is thought 'to re% ate.te the venalization problem mentioned above and not ice daange.;

Dogwood standings at this site showed evidence of transplant damage again in 1983, although most plants show evidense of recovery.

Sweet elover and erown vetah growing at this site showed no signs of ice smothering.

Site #1 was characteristie of crown vetch growing on the banks of the pond containment dike. Growth was exoellent and there was little sign of the Volutella canker disease seen in the 1984 survey.

Site #4 was contiguous with observation site #7 used in the fog and rise ice monitoring reports. Dieback was noted only in a row of old Osage orange trees growing adjacent to a pasture.

Site #5 was loested between fog and rise lee observation sites M and M. A new home with new landscape tree plantings was located at this site. These plantings coeurred in 1984 and did not show los or winter damage.

site M was located at 0.7 miles west of fog and rise toe observation site M. An old planting of hard amples showed evidsnee of diebeek relating to decay at this abandoned building site. There was no evidense of ice damage.
