The temperate forest flora-fauna of GHNP represents the western most extension of the Sino-Japanese Region. The high altitude ecosystem of the Northwest Himalaya has common plant elements with the adjacent Western and Central Asiatic region. As a result of its 4,100m elevation range the Park has a diversity of zones with their representative flora and fauna, such as alpine, glacial, temperate, and sub tropical forests. These biogeographic elements are result of geological evolution of Himalaya which continues today from the action of plate tectonics and continental drift. Over 100 million years ago, the Indian sub-continent broke off from the large, southern landmass, Gondwanaland and moved north. It eventually slammed into the northern land mass, Laurasia, and formed the gigantic folded mountains of the Himalaya. Due to this union of Gondwanaland and Asiatic landmasses, exchange of flora and fauna was possible and this ultimately led to the unique biogeographical features in the region.
