Medicinal Plant Trade in Sierra Leone: Threats and Opportunities for Conservation

This study used a quantitative market survey to examine the ecological importance of the medicinal plant trade in Sierra Leone and the existing trading systems, so that it could be determined (1) if trade has a negative impact on the species traded, and/or (2) if trade could be used to support conservation projects. We interviewed vendors in three major cities and two towns and carried out focus-group discussions among collectors at forest edge communities. In the markets, specimen samples were collected and identified. In several forests, observations were made on harvesting techniques and relative abundance. More than 40 species are traded in urban markets, nine of which are the most frequently traded. Some plants are transported great distances to reach the urban markets, especially Xylopia aethiopica (Dunal) A.Rich. and Garcinia kola Heckel. Certain species might not be sustainably harvested depending on the collector practices (e.g., ring debarking, tree felling), and this might threaten these species, especially Piper guineense Schumach. & Thonn. However, results also suggest that the trade of some species could be promoted as an alternative livelihood strategy for edge communities of forest reserves. In this latter case, special attention should be paid to sustainable harvesting techniques. © 2014 The New York Botanical Garden.
