Abstract

Studies on population assessment and biomass variation in selected populations of Swertia angustifolia were undertaken in west Himalaya. Low population density across the surveyed populations indicates poor availability of the species in study area. Species showed random distribution and higher frequency of occurrence in most of the population, which is the indicator of better potential of the species in these sites. Density was positively correlated with biomass. The biomass showed peak value in senescence phase and thus has positive consequences of harvesting for the survival of the species. 

Key words: Endangered, conservation, Himalaya, Swertia angustifolia, medicinal plant.
