Ecological status of Alpine Medicinal and Aromatic Plants of Western Himalaya.

The ecological status of medicinal and aromatic plants species (MAPs) in the alpine region of the Western Himalaya was assessed to identify the current threats on these MAPs. Of the 400 MAPs reported from the alpine region of Uttarakhand, 50 highly used and commercially exploited MAPs were prioritized for assessment. A semistructured questionnaire survey was used in the representative sites (50) of the alpine landscape based on the information, parts used, locality of occurrence, and socioeconomic status. Field surveys were conducted using Rapid Mapping Exercise (RME) (4 plots of 1 × 1 m at every 50 m distance, total 40 plots in one transect) along the elevation and habitat gradient to assess the population status of species. The intensity of threat was evaluated using a rapid threat assessment (RTA) approach using eight criteria viz., plant parts used, life forms, habitat, endemism, population size, use pattern, trade, and threat status. The recorded magnitude of threats revealed that Angelica glauca, Nardostachys jatamansi, Aconitum heterophyllum, and Rheum australe were the most vulnerable. Roots/rhizomes (68%) were the most frequently used plant parts of MAPs, followed by inflorescence/fruit (19%). [ABSTRACT FROM AUTHOR]
