Bounded to the East by the Himalayan Mountains, the Great Himalayan National Park (GHNP) forms part of the boundary between four ecological zones: (1) the dry deserts of interior Asia and the well-watered lowlands of the Indian plains, (2) the Oriental and Palearctic faunal realms, (3) the high plateau of Tibet and the jumbled Himalayan peaks, and (4) the catchments of the Beas and Sutlej Rivers, both mighty tributaries of the Indus. Because of its complex geography and its grea
t variations in altitude, the limited area of the Park encompasses an enormous range of species, which span the subtropical to the alpine and include those characteristic of the south-east Asian forests as well as those found across Siberia and the Asian steppes. Few ecological sanctuaries present such a variety of wildlife habitat and biological diversity in such a small area.

Few ecological sanctuaries present such a variety of wildlife habitat and biological diversity in such a small area.The Park is the foremost priority for conservation in the North-West Himalayas. Its remote location has thus far spared the Park many of the problems that have affected natural ecosystems elsewhere in India. The occurrence of temperate and alpine ecosystems in a geographically compact area make GHNP the most significant and biggest conservation unit in the Western Himalayas. This status further protects the relatively inaccessible rugged terrain which represents the ecology, geology, and biota characteristic of the North-West Himalayas.
The boundaries of GHNP are contiguous with the Pin Valley National Park in Trans-Himalaya, the Rupi-Bhawa Wildlife Sanctuary in Sutlej watershed, and the Kanawar Wildlife Sanctuary. Together the varied wildlife habitats of these protected areas support the full range of Western Himalayan biodiversity, from tropical to alpine and Tibetan. Thus, the Park is a crucial protected area because it connects other islands of biodiversity. This increases the availability of migration routes between protected areas which is essential for the survival of many animals.
From the roadhead at Gushaini or Neuli, the trails leading to the Park pass through subtropical pine forests. They rise towards the dense coniferous and mixed deciduous woods of the temperate zone, which is entered at about 1800 m. In summer, the spreading canopy of green and silver oaks and horse chestnuts provide welcome relief from the sun. Above this zone, at about 2500 m, cool-temperate forests of fir and spruce occur on northerly slopes, with brown oaks on southerly aspects. Above 3000 m, these forests grade gently into a sub-alpine zone of birches and rhododendrons, diminishing in size as the tree line is approached. Above 3000-3200 m, we find alpine meadows, splashed with a great variety of flowers and higher again is the realm of rock and ice that rules the high peaks and ridges.
Among the large mammals that visitors may encounter, there are several species of herbivores that are characteristic of the Park. The Goral (Naemorhedus goral), a small goat-antelope is found in the lower forests; the Himalayan Tahr (Hemitragus jemlahicus) in the higher forests, and above the tree-line the Bharal, or Blue Sheep (Pseudois nayaur). These mammals are the prey for Leopards (in the forest zone) and Snow Leopards (above tree-line). Himalayan Black Bears inhabit the forests, while Asiatic brown Bears occur on the alpine meadows.
Among birds, the Park is well known as the most important locality in India for the endangered Western Tragopan. Four other species of pheasant occur in or adjacent to the Park, the one most likely to be seen by visitors is the Himalayan Monal, an abundant bird in the higher forests, although rather shy. Raptors are also a prominent feature of the Park, with Lammergeiers, Himalayan Griffon Vultures, and Golden Eagles being seen regularly. A great variety of other birds occurs, some of which reach their western limit in the Park.
The flora of GHNP shows affinities with Mediterranean, Tibetan, and the Peninsular Indian region. For example, species of Valerians, Dactylorhiza, Yew, and Leycesteria are typical taxa which extend to Afghanistan and west China. Other affinities that are met with here are in form of buckthorn (Hippophae) of palaearctic region; Cedar trees, herbaceous Violets, and grasses such as Poa of Mediterranean region; and spurge (Euphorbia) shrubs of Peninsular India. In addition, GHNP has a number of endemic species of Himalayas, for example several species of balsams (Impatiens), species of Androsace, Hedysarum, Draba (Whitlow grass),etc.
Many visitors are drawn to the mountains and the wildlife of the Park. The indigenous culture of the mountain villages, adjacent to the Park, also offer unique experiences for the traveler. Isolated for centuries from the large urban centers, these remote hamlets developed a highly distinctive culture, based on the worship of local deities (devta) which are celebrated in numerous local, regional and national festivals. From the characteristic architecture of the houses and temples, and the folk wood carvings that decorate them, to the silver jewelry and woven wool shawls and blankets, there is a great range of local crafts to see.
Nor should the visitor ignore the clear interdependence of people and environment that is characteristic of traditional lifestyles. Although the high valleys of the Park are remote and support a varied flora and fauna, the signs of traditional use are everywhere. They form an intimate part of the Park's ecology. An understanding of the role that traditional practices (e.g., grazing, burning, and medicinal plant collection) have had on the Park's biota is important before we can fully appreciate the forces that have contributed to development of the ecosystems we see today.
