- Abstract
The main aim of the study was to predict the potential distribution, trade, and conservation of Rauvolfia serpentina in Nepal. We used 117 well-dispersed species occurrence points to run the Maximum Entropy (MaxEnt) model with bioclimatic, topographic, vegetation-related, and anthropogenic variables. Twenty-four percent of Nepal's total land area is a potential habitat for R. serpentina. The potential area of R. serpentina in the protected area is 5,230.92 km² (15%). The accuracy of the model was excellent with an average Area Under the Receiver Operating Characteristic Curve (AUC) of 0.92±0.004 with an average True Skill Statistics (TSS) of 0.62±0.03. Nepal's Siwalik region is the best suitable habitat, followed by Terai and Middle Mountain. It is slightly suited in the High Mountains, and it is completely unsuitable in the Himalayas. The increasing price of R. serpentina was a good indication for commercial cultivation (average annual increment of price = 0.39%). Based on the scores obtained, the more suitable area (core Terai) showed the highest threat. The trade of R. serpentina is very minimal in Nepal due to government restrictions and international laws (IUCN and CITES). Cultivation practices are the major key activities that lead to protecting this species in the natural environment
