Because of its complex geography and its great variations in altitude, Kullu is home to an enormous range of species, which span the subtropical to the alpine. The common trees in the Kullu hills belong to the conifer species (deodar, pine, spruce, fir). Several species of medicinal plants like Hath Panja (Dactylorhiza hatageria) and Brahma Kamal (Saussurea obvallata) grow luxuriously in the valley. The valley is known for the presence of the majestic Snow-leopard, the Himalayan brown bear and the Himalayan Tahr. The Western Tragopan (the state bird of Himachal Pradesh) and the Monal pheasant are the prominent birds species found in the region.
The Great Himalayan National Park is the repository of the great biodiversity of the region. It was established in 1984 and in 2014 the GHNP was added by the UNESCO to the list of World Heritage Sites.
