Seven years after clear-cutting, the developing stand in a clear-cut area 
.s a mixture of vines, trees, and shrub species 4-6 meters high. We studied 
gray squirrel utilization and squirrel food production for 2 years, 1973-7*5 
in a 5.8-acre 7-year-old clear-cut. J * 
Only two individual squirrels were captured in the 7-year clear-cut during 
2 years of 1.vetrapp.ng, both of which were 1 year or less in age. The first 
year .ve traps were operated throughout the clear-cut, and all captures were 
made less than 28 meters from the forest edge. The second year we closed all 
the traps in the outer perimeter to see if squirrels were foraging into the 
interior of the clear-cut. During November a squirrel was taken 56 meters 
from the edge, nearly in the center of the clear-cut (the center of the cut 
was 66 meters from the edge). 
Squirrel track counts on snow during two winters revealed that sauirrels 
were penetrating less than 45 meters into the clear-cut. 
Production °f squirrel foods was significantly higher in the 7-year cut 
compared wjth the 1- or 2-year clear-cuts at Danville and Truetown. However, 
st of this production consisted of perishable summer foods, principally 
SmaH amounts of 9' 11 mushrooms and flowering dogwood were also 
found, but there were no foods suitable for fall and winter storage. 
There were no leaf nests built in the 7-year clear-cut and, of course, 
no den cavities suitable for nesting. 
. Th V s > f° r 7 years and probably 10 years after clear-cutting, squirrels 
If '? the UnC T f ?r est surrour| d i ng the clear-cut utilize only the perimeter 
of the clear-cut for limited foraging during the summer months, rarely 
penetrating beyond about 30 meters from the uncut edge. In winter, squirrels 
penetrate deeper into the cut, but with no shelter or food avaiIab e ?hey do 
not remain very long. y 
It seems likely that during the first 10 years after cutting, squirrels 
rarely penetrate to the center of clear-cuts wider than 70 meters.
