Illegal harvesting and livestock grazing threaten the endangered orchid (D. Don) Soó in Nepalese Himalaya.

Harvesting of orchids for medicine and salep production is a traditional practice, and increasing market demand is spurring illegal harvest. Ethno-ecological studies in combination with the effect of anthropogenic disturbance are lacking for orchids. We compared population density and structure, and tuber biomass of (D.

(Asteraceae), a new species from Humla, Nepal Himalayas.

A new species S.K.Ghimire & H.

Harvest effects on density and biomass of vary along environmental gradients in the Nepalese Himalayas.

A surprisingly large number of species potentially threatened by human harvest lack quantitative ecological studies incorporating harvest effects, especially clonal species in the alpine Himalayas. We studied density and biomass variation of a threatened medicinal herb, to examine the effect of harvest on plant performance. The study covered two regions with contrasting harvest situations-one with open-access and another protected from commercial harvesting.
