Abstract: The wild biodiversity in ecosystems is a vital element in agrobiodiversity. The timber volume and important value index of plant species of tree layer, and plant species diversity in community forest and in holly hill forest of Daka village, Xishuangban-na, south Yunnan, China were studied. The results showed that the timber volume in holly hill was 1.91 times of community for-est, as the local farmer for timber consumption had collected the latter. Shannon - Wieimer diversity index (H) of community forest was 2.57, less than that of holly hills, which were 2.84.
