What is a typical sign of Ursus americanus damaging trees?

The indication of Ursus americanus, commonly known as the American black bear, damaging trees often manifests through gnawing on the bark. This behavior is a result of the bear's foraging habits, as they typically use their strong jaws and sharp teeth to strip the bark for access to the nutritious cambium layer underneath. The gnawed bark can create distinct marks and may indicate a bears’ presence in the area, while also potentially causing damage to the tree itself.

Other signs of tree damage, such as broken branches, scuffed bark, or missing leaves, may be associated with various other factors or animals. Broken branches could occur from natural causes or weather, scuffed bark might be related to deer rubbing, and missing leaves can be attributed to insects or other herbivores. However, gnawed bark specifically points toward the distinct behavior of bears seeking food, making it the most accurate sign of damage attributed to Ursus americanus.
