Diversity of Medicinal and Food Plants as Non-timber Forest Products in Naban River Watershed National Nature Reserve (China): Implications for Livelihood Improvement and Biodiversity Conservation

摘要

Diversity of Medicinal and Food Plants as Non-timber Forest Products in Naban River Watershed National Nature Reserve (China): Implications for Livelihood Improvement and Biodiversity Conservation. Non-timber forest products (NTFPs) play an important role in rural livelihoods. People living in and around forests are dependent on a variety of NTFPs for their subsistence and for income generation. This paper gives a general overview on the diversity of NTFPs in the Naban River Watershed National Nature Reserve, with a focus on medicinal and food plants. Data on NTFPs use were gathered through an ethnobotanical inventory with semistructured, free-listing, and household socioeconomic interviews. Interviews were supplemented with voucher collections. Bamboo shoots were analyzed further as proxy NTPF. It was hypothesized that there is no significant difference between collection amounts of bamboo shoots and their contribution to the household income between the villages studied. A rapid vulnerability assessment (RVA) was conducted to identify vulnerable and threatened species. A total of 480 plant species (25% of recorded flora) from 117 families and 334 genera are used as NTFPs by the local people. Results revealed that there is a significant difference in the collection and contribution of bamboo shoots to household income among the villages. However, their contribution to per-capita income is very low, and they are mainly used in households. Vulnerability assessment showed that most of the medicinal species have moderate vulnerable status and that most of the food species have less vulnerable status. Some medicinal plants, such as Paris polyphylla var. yunnanensis, are overexploited and getting scarce. Sustainable harvest and management strategies should be implemented to prevent overexploitation of these species.
