Climate change and global warming are well acknowledged threats today, which affected the whole world biodiversity. Review of the literature revealed that regions with higher elevations are more vulnerable to the bad effect of climate change. The Indian Himalayan region, one among the mega hot spot of biodiversity is also the repository of valuable medicinal plants described in Ayurveda. Due to climate change the medicinal plant diversity of this region is on high stress or may be extinct in long run. From climate change, it has been observed the changes of alpine ecosystem, habitat fragmentation, shifting range of distribution, change in phenology pattern, change in secondary metabolites and invasion of new species, which have negative impact on the existing resources of medicinal plants. Ayurveda, the ancient system of medicine which solely depends on the plant resources for alleviating the illness will be highly affected in future due to the impact of climate change.

The erosion of plant biodiversity is a matter of global concern. Due to unawareness the building blocks of entire ecosystems are disappearing. Some medicinal plants like Taxus baccata Linn., Thymus serpyllum Linn., Coleus forskohli Will., Oroxylum indicum Linn., Valeriana hardwickii Wall., Malaxis acuminata D. Don, Habenaria edgeworthii Hook. f.ex.Collett., Costus speciosus (Koen.) Sm., Dioscorea deltodea Wall., Gloriosa superba Linn., Polygonatum cirrhifolium Wall. and Polygonatum verticillatum Linn., Thalictrum foliolosum DC., Berberis aristata DC., Baliospermum montanum Will., Bergenia ciliata (Haworth) Sternb., Clerodendrum serratum Linn., Valeriana jatamansii Jones, Celastrus paniculatus Will., Habenaria intermedeia D. Don, and Curculigo orchioides Gaerth are reached on the border of extinction. The 2008 IUCN Red List shows that the number of threatened plant species is increasing gradually (IUCN 2008). Therefore, there is an immediate need for conservation steps to be taken up along with promotion of conservation of medicinal plants.

Studies on population assessment and threat categorization in selected populations of Malaxis acuminate D. Don., a rare, terrestrial, endangered medicinal orchid of Himalayan region and an important "Astverga" plant were undertaken. Status was determined on siteto- site basis as well as for entire Kumaun region. Based on species occurrence in selected areas, the species were identified as critically endangered to endangered in different sites studied. The results also revealed that natural distribution of the species was narrowing down due to habitat destruction and over exploitation. Immediate remedial measures are needed for the conservation of natural sites to ensure sustainable mode of utilization.
