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 great 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.
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.
