My woods seems to support 8 squirrels. I've had Uncle Frank shoot some a couple years and each time the next year came around there were 8 squirrels. Of course when the walnuts and acorns are falling, I have visitors from every direction. Once the surplus foodstuffs are gone, so are the extra squirrels. Eight seems to be the limit. I've never checked the gully-woods to count squirrels, but except for harvest time, they seem to stay away.
