The growing demand for medicinal and aromatic plants (MAPs) that are harvested from the wild exerts an increasing pressure on these important natural resources of the Himalayas. In the present study, 126 species of higher plants from the Muktinath Valley, Kali Gandkhi, in Central Nepal are documented. Endangerment was assessed by adapting the Rapid Vulnerability Approach (RVA). The RVA-test shows that seven of these species have a “high potential endangerment”, 102 species a “moderate potential endangerment” and 17 species “no potential endangerment”. For valuation of the reliability of the RVA-test, a statistical analysis was conducted. The six indicators used in this study do not show any or only minor inter-correlations, and resulting threat values are independent from each other. We can thus show that each individual indicator has a significant effect on the assessment of endangerment. As a result, the RVA as used herein is suitable for an approximate assessment of endangerment of MAPs.
