In this thesis I synthesized different aspects related to diversity, distribution, uses and conservation of medicinal plants in Nepal and also have attempted to recommend guidelines for sustainability of two highly used alpine plant species. The over-harvesting or human induced activities are not the only problem for biodiversity but recently invasion of alien species has also emerged as serious problem in Nepal. I thus also attempted to analyze the effect of invasive species on community composition in the last paper. The first two papers deal with diversity, distribution, uses and harvesting. Paper I showed that medicinal plants in Nepal have unimodal relationship with elevation and the maximum total species richness is at 1000 m. Paper II which deals with the uses of medicinal plants in the Humla region, west Nepal showed that there are 161 medicinal plant species belonging to 61 families and 106 genera used for treating 72 human and 7 veterinary ailments. Medicinal plants in Humla were mostly collected in wild. This induces a serious threat to diversity of the medicinal plants and it is therefore necessary to develop proper management guidelines for their harvesting in wild and/or their domestication. Rheum australe, an endemic plant to west Himalayan region, is widely used plant in traditional...
