Floristic Diversity of the Himalaya in Relation to Climate Change: Status, Values and Conservation
Keywords:Indian Himalayan region, floristic diversity, orchids, medicinal and wild edible, factors, climate change, conservation initiatives
The Himalayan region is very well known for the unique ecosystems. The
Indian Himalayan Region (IHR) forms the major part of the Himalayan
region. The vegetation along an altitudinal gradient comprises of tropical,
sub-tropical, temperate, sub-alpine and alpine types and supports a great
variety of forests with unique species that vary from east to west and from low
to high altitudes. The present study is based on the review of literature and
surveys in some parts of the IHR. A total of 10,503 species (10,452 species
of Angiosperms and 51 species of Gymnosperms) are reported from the
Himalayan region. The Indian Himalayan Region (IHR) represents 18,940
species of plants representing Angiosperms, Gymnosperms, Pteridophytes,
Bryophytes, Lichens, and Fungi. A total of 6745 species of Angiosperms (604
trees, 1049 shrubs & 5092 herbs) belonging to 225 families, 1768 genera are
recorded from the Trans, North-West and West Himalaya based on surveys
and review of literature. Diversity of the orchids, medicinal plants, wild edi-
bles, other economically important plants, factors affecting floristic diversity,
impact of climate change and conservation initiatives have been discussed.
