[Wikipedia] Wildlife Value: S. geyeriana is browsed in the wild by moose (Alces alces) and elk (Cervus canadensis) in all seasons, but is essential during winter.[12]
Grouse (Phasianidae subf. Tetraoninae), ducks (Anatidae), and other small birds, and small mammals regularly consume the buds, catkins, shoots, and leaves of G. geyeriana; and it is one of many Salix species used in the construction of beaver dams for North American beavers (Castor canadensis).
