weeping willow damaged by beaver

Asked February 4, 2019, 3:47 PM EST

A large mature weeping willow tree was damage by a beaver last fall. Don't expect a return of beaver until ice in river is gone. I know how to prevent beave doing further damage. I am concerned on how I may assist the tree in surviving. The tree is large and the trunk is about 30+" diameter. The bark is gone about 20" high and about 25" around. This damaged area is taken from a picture sent me from a neighbor. From the picture it looks like only the bark has been removed. Thanks for any thoughts you may provide. Thanks Del

Generally, trees cannot tolerate losing more than about 25% of the bark of their circumference. Here is a helpful page: http://extension.umd.edu/hgic/topics/how-do-you-decide-when-remove-tree

Willows can send up shoots from the base, and this may result from the beaver damage. You could choose the strongest shoot, remove the others and grow a new tree. Meanwhile, just try to water it during droughts. Do not stress it by fertilizing heavily.
