Abstract

Alpine and subalpine regions of Kumaun Himalaya were surveyed qualitatively and quantitatively for the population study to determine the status of Aconitum ferox and A. heterophyllum. Low population density across the surveyed populations and restricted distribution to specific pockets indicates poor availability of the species in the study area. Illegal and over exploitation of these species pose threat to their existence. The present study clarifies the population structure of identified aconite species in Kumaun Himalaya. Observations reveal that on the basis of six attributes (that is habitat preference, distribution range, population size, use pattern, extraction trend, native and endemic species) used to assign threat categories, both the Aconitum species are endangered.

Key words: Endangered, Himalaya, Aconitum heterophyllum, Aconitum ferox, medicinal plant.
