The tree prefers wet soils and is commonly found in riparian forests, along riverbanks, and in floodplains. It can also tolerate periodic flooding. Ecological Importance The Eastern Cottonwood is an important species in riparian ecosystems because it provides food, shelter, and nesting sites for a variety of wildlife. The tree's large size and rapid growth make it an excellent source of habitat for many species. The tree's leaves are a source of food for the caterpillars of several butterfly species, including the Eastern Tiger Swallowtail and the Viceroy. The tree's seeds and buds are eaten by birds, and its bark is used by beavers for building dams and lodges. The tree also helps to stabilize riverbanks and prevent soil erosion.
