Wildlife Benefits:
River Birch supports 411 species of caterpillars, including the Eastern Tiger Swallowtail. Seeds are eaten by many songbirds along with small mammals. Trees provide cover for animals and nesting sites for birds. The male catkins can be eaten by birds and squirrels in winter and early spring. Beavers use branches for construction in dams.
