    Description

    The overall objective of this project was to determine the effects of defoliation on gray squirrel habitat. We will evaluate the existing Habitat Suitability Index (HSI) Model for gray squirrels on the University Forest and determine the effects of thinning on HSI values computed for thinned and unthinned stands. Habitat variables used in the U. S. Fish and Wildlife Service gray squirrel model were measured on 8 10-12 ha treatment (to be thinned in spring 1990) and 8 unthinned stands on the University Forest, Morgantown, WV, and 3 other nearby hardwood tracts. Six different habitat variables were measured on 112 0.04-ha plots using standard forest measurement techniques. Squirrel abundance was measured on these same stands from 6:W-9:W AM from June-October 1989 using time-area counts.
