When does Ursus americanus commonly cause feeding damage to trees?

Ursus americanus, commonly known as the American black bear, typically causes feeding damage to trees during early spring. This is the time when bears emerge from their hibernation and their instinctual behavior leads them to forage for food.

During early spring, the availability of natural food sources is often limited as the plants and trees are just beginning to leaf out and produce new growth. As a result, black bears may damage trees in search of tender shoots and the cambium layer of the bark, which is rich in nutrients.

Understanding this seasonal behavior is crucial for managing and mitigating the impacts of bear feeding on trees, especially for conservation efforts and forestry management. This timing contrasts with the other seasons, where bears have different feeding patterns and natural food sources are more abundant, thereby reducing the likelihood of significant tree damage.
