摘要
We investigated the distribution and resource values of liana species assessed in six hill complexes of southern Eastern Ghats, India. 143 liana species （DBH （diameter at breast height） ≥1.5 cm） and 32,033 liana individuals were recorded from 110 transects （0.5 ha each covering 55 ha area） in the study sites. The resource values of lianas were broadly categorized into ecological and economic importance. About 90% （129） of liana species and 96% （30,564） of liana individuals were established ecological/economic values. Fruit rewards provided by 76 species and 20,325 individuals constituted the major resource of ecological importance. 82 species and 21,457 liana individuals are of economic importance as medicine, edible fruits, edible and medicinal values, and yet others are used for different domestic purposes including furniture, fuel wood, rope making etc.. Ecologically, the prevalence of succulent diaspores in lianas of Indian Eastern Ghats indicates the animal dependence of many liana species for dispersal and underlines the need for a holistic and whole-forest conservation approach in maintaining forest biodiversity.
