Many baby squirrels are killed or orphaned during tree cutting season. Peak season varies on the species of squirrel and should be inspected accordingly. Arborist should not be allowed to cut trees where nests are present during peak baby season. Arborist should implement an inspection checklist to be sure no babies are present before a tree is cut down. If babies are present, the arborist should not be allowed to cut the tree until the babies/mother have moved on.
