摘要

Over exploitation and overgrazing are considered major factors for decreasing plant species diversity. However, we doneed some more exploration on the types of anthropogenic disturbances responsible for variation in species’ decline amongdifferent regions. Therefore, the current study was conducted in a temperate Hindukush region of Pakistan with the aim toassess human settlements’ pressure on the diversity of medicinal plants. Field data was collected from 15 plots, of which 5plots each were randomly selected at three distant locations in derived woodland forest. Near to community plots wereheavily disturbed due to natives’ proximity, 2 kilometer away plots from the native community were moderately disturbed,while 4 kilometer away plots were under the disturbance regime from temporary settlers (Nomads). We have found all 10studied medicinal plant species at 2 Km distance followed by 8 species found at 4 km distance. Economically importantspecies such as Bergenia ciliata, Paeonia emodi, Podophyllum emodi, Valeriana jatamansi and Viola canescens werecompletely absent near village. Similarly, density (8.72 n m-2) and species richness (8.2 n 40 m-2) were found significantlyhighest at 2 km distance than other locations. Detrended Correspondence Analysis (DCA) showed that among forest standstructural variables, slope was the influencing variable related to the density of only Bergenia ciliata. In conclusions,moderate disturbance is associated to increase in the diversity of medicinal plants, while high anthropogenic pressures theotherwise. Hence, effective management strategies may be adopted to conserve such precious eroding flora.
