Himachal has more than 50% green area and is major source of herbal medicines and is famous for various nature treks thousands of people criss cross all of the Himachal on foot, whether it is ManiMahesh annual trek or you take Parvathi valley trek famous with foreigners, almost all of Himachal carries huge forests.
However with ever growing population, forests are in grave danger, I think the efforts of volunteers come here, people need to be made aware that their own existence depends upon nature.
I think it is a great effort by this group and we need to be a part of it.
Here is little information about the park from http://www.greathimalayannationalpark.com:
GHNP is a major source of water for the rural and urban centers of the region with four major rivers of the area originating from the glaciers in the Park. It is also a source of sustenance and livelihood for the local community living close to GHNP. In addition to lumber, the forest environment provides local people with Non- Timber Forest Produce (NTFP) such as honey, fruit nuts, bark of birch and yew, flowers and fuel wood.
Globally, as well as locally, the Great Himalayan National Park has a very high public profile. The international community regards at it as a pilot site where the community based Biodiversity Conservation approach is being tested. The local people in the Ecozone (or Buffer Zone adjacent to the park) of GHNP recognize the fact that they have overexploited the medicinal herbs and NTFPs, and their sheep and goats have overgrazed the pastures.
In 1980, the Himachal Wildlife Project (HWP) surveyed the upper Beas region to help establish the boundaries of the park. An area comprising the watersheds of Jiwa, Sainj, and Tirthan rivers became the Great Himalayan National Park in 1984. Starting from an altitude of 1,700 metres above mean sea level, the highest peak within the Park approaches almost 5,800 metres. The area of the National Park at the moment is 754.4 sq kms and it is naturally protected on the northern, eastern and southern boundaries by permanent snow or steep ridges. To facilitate conservation a 5 km wide buffer area, extending from the western periphery of the Park, has been classified as theEcodevelopment Project Area (EPA) or Ecozone.
The EPA has an area of 326.6 sq km (including 61 sq kms of Tirthan wildlife sanctuary) with about 120 small villages, comprising 1600 households with a population of about 16,000. Since, the Indian Wildlife Protection Act 1972 does not permit any habitation in the National Park, an area of 90 sq. kms. in Sainj valley encompassing the two villages of Shakti and Marore has been classified as Sainj Wildlife Sanctuary (WLS). These two villages although technically “outside” the National Park, are physically located between two parts of GHNP. Thus the total area under the National Park administration is 1,171 sq km.
