Ecology and Management of Sguirrels

Foresters consider grape vines a threat to tree growth, particularly on good 
sites, and often recommend the removal of all climbing vines. Wildlife biologists, 
however, consider grape vines important food producers for many wildlife species. 
In an attempt to resolve conflicts between foresters and biologists regarding 
grape vines, biologists in Illinois, Ohio, and West Virginia have cooperated in 
a study of the use of grape vines by gray and fox squirrels as anchors for leaf 
nest attachment. 
Counts of leaf nests were made after leaf fall for 1 to 7 years on 6 study 
areas (1 area in West Virginia, 3 in Ohio, and 2 in Illinois). Leaf nests were 
recorded as usable or not usable by squirrels and the presence or absence of a 
grape vine was noted for each nest. A sample of the trees >5 inches dbh was 
taken on each study area and the presence or absence of a grape vine was recorded 
for each tree in the sample. 
A total of 3,799 leaf nests was counted, and on all areas, the percentage of 
leaf nests with grape vines exceeded the percentage of trees with grape vines. 
The number of nests associated with grape vines compared with the number expected 
from the percentage of trees with grape vines was significant (P<0.05) for all 
tree species except a few in which the trends were the same, but the sample sizes 
were too small to attain significance.
