In June 2014, the Great Himalayan National Park was added to the UNESCO list of World Heritage Sites,[1] under the criterion of "outstanding significance for biodiversity conservation".

As a result of its 4,100 m elevation range the park has a diversity of zones with their representative flora and fauna, such as alpine, glacial, temperate, and subtropical forests.

These biogeographic elements are result of geological evolution of Himalaya which continues today from the action of plate tectonics and continental drift.

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.

1999: GHNP instated as India’s newest national park; compensation awarded to local communities previously identified as having traditional forest rights there.

2010: Proposal to declare 710 sq km Parvati watershed as Khirganga National Park in the north of GHNP to strengthen the conservation efforts.

2013: GHNP's nomination considered and put in referral list; Management council constituted by involving all the heads of 13 local governing bodies.

From the lofty pines and spruces and the great, spreading horse chestnuts of the lower valleys, to the dense cushions and prostrate branches of the alpine herbs and junipers, the park presents an endless variety of vegetation.
