Conservation of endangered species requires a thorough understanding of the dynamics of small populations. In the present study, we investigated the diversity and the dynamics of G copallifera communities in two different types of land use history, a protected area （stated forest of Como6-Leraba） and an unprotected area （the woodlands of Toumi and Timba）. A total of 17 rectangular plots （50 m × 20 m） were sampled in both protected and unprotected areas. All woody species were systematically identified, measured and classified into diameter and height classes. In the two different types of land use, the dynamics of G. copallifera＇s communities were good, and the diversities were similar and low with high β diversity.展开更多
