The majority of bear activity occurs between 1000 and 2500 meters altitude. The range of activity of any individual bear is roughly 30 to 100 square kilometers, though a few reach as high as 200 square kilometers (or one fifth of the area of Yushan National Park). About half of the bears left the area of the park at some point, exposing themselves to risk outside the protected zone.
黑熊最常活動的高度是海拔 1,000 ~ 2,500 公尺，每隻熊的平均活動範圍在 30 ~ 100 平方公里，有些甚至高達 200 平方公里（玉山國家公園 1/5 範圍）；其中有半數會跑出國家公園外，讓自己暴露於無保護的險境之中。
