Profound field inventory and monitoring of threatened species habitats are cost-prohibitive, if there is little known about the distribution of species. Malaxis muscifera is a habitat specific, threatened medicinal orchid constitute of Astavarga which grows between 2500-3700 m in the alpine region of Himalaya. Its population decline is closely link...

The availability of medical plants across six major habitats viz., mixed herbaceous meadow, tall forbs, Danthonia grassy slope, shrubbies, Kobresia sedge and cushinoid were assessed across meadows above 3000m asl. Rapid...

Kumaun Himalaya is a home to various threatened medicinal and aromatic plants. Picrorhiza kurroa is a threatened medicinal plant useful in curing many diseases in Indian Himalayan region. Due to overharvesting from the wild its population is decreasing at an alarming rate. The present study attempted to assess its availability and predict highly su...

Medicinal plants are known for their traditional and modern medicinal values to treat health disorders. Dactylorhiza hatagirea (known as Hattajari and Salampanja) is one of these medicinal plants, which is highly praised and valued medicinal plant in alpine regions. The plant has been widely used by the local inhabitants for treating various ailmen...

Grasslands are the world’s most extensive terrestrial ecosystem, which provides a variety of services for humans, such as carbon storage, food production, crop pollination, pest regulation, and are a major feed source for livestock. However, grasslands are today one of the most endangered ecosystems due to land-use change, agricultural intensificat...

The Indian Himalayan region arbours rich array of Medicinal and Aromatic plants (MAPs) owing to its diverse topography and climatic conditions. However, under the contemporary changes in the Himalaya, excessive resource use, changing climate, increasing viz., developmental and tourism activities, a little is known about the alpine vegetation respon...

Gastrochilus affinis (King & Pantl.) Schltr. is reported here for the first time from Western Himalaya. Gastrochilus nepalensis Raskoti, a species from Nepal described in 2015 is reduced to synonymy under G. affinis. A note on typification of G. affinis is also provided in the present communication.

Increase in endemism with elevation is a common feature in Himalayas because of increased isolation of higher areas like treelines. To protect species of treeline, we at least need to record their numbers and distribution. We estimated that the total number of tree species in Himalayan treeline is 58, and they belong to 14 genera and 8 families. It...
