Extent of this site: situated between the Da-an and the Tachia Rivers, and includes the Dahsuehshan forest recreational area, the Wushihkeng low-elevation research station of the Taiwan Endemic Species Research Institute (TESRI), and the Hsuehshankeng Nature Reserve of Miaoli County. On the south are Pochinjia Mt., Hsaolai River, and Wuwowei Mt.; on the east is Hsiaohsueh River; to the west is Wushihkeng River; and to the north is Mabihao River. Because the change in elevation is great, stretches across four types of forest types of subtropical, warm, temperate, and frigid forest zones. Because Dahsuehshan is a mid to high-elevation mountain area, the area’s birds will descend to lower elevations at Wushihkeng and Hsuehshankeng in the winter, and the ecology of these three areas are very Closely related. Within this area there are several settlements of Atayal Aboriginals.
