Ridges were significantly dominant over slopes and valleys in terms of total bear-created canopy gaps. The annual rate of bear-created canopy gap formation reached 141.3 m2 ha〓1 yr〓1 on ridges, which were hot spots in terms of black bear activity. This rate was approximately 6.6 times that of tree-fall gap formation on ridges at this study site. Canopy disturbance created by black bears in the middle‐top canopy layers were key for improving light conditions and accelerating fruiting by fleshy-fruited plants. Camera-trap data showed that birds and mammals used bear shelves as habitats for foraging, hoarding, resting, and reproducing.

就熊造成的树冠间隙总量而言，山脊明显优于斜坡和山谷。山脊上熊造成的树冠间隙年形成率达到141.3平方米·公顷〓1年〓1，这是黑熊活动的热点地区。该比率约为本研究地点山脊上树木倒塌间隙形成率的 6.6 倍。黑熊在中顶部树冠层造成的树冠干扰是改善光照条件和加速肉质植物结果的关键。相机陷阱数据显示，鸟类和哺乳动物利用熊架作为觅食、囤积、休息和繁殖的栖息地。
