Initially constituted in 1984, GHNP was formally declared a National Park in 1999, covering an area of 754.4 sq kms. In 1994, two major changes were made in land use around the Park. A buffer zone of 5 km from the Park’s western boundary, covering 265.6 sq km. and including 2,300 households in 160 villages, was delineated as an Ecozone. Most of the population (about 15,000 to 16,000 people) in the
Ecozone are poor and dependent on natural resources for their livelihoods.The second change was the creation of the Sainj Wildlife Sanctuary (90 sq km) around the three villages of Shagwar, Shakti, and Marore. On the southern edge of the GHNP, another Protected Area (PA) was declared, known as Tirthan Wildlife Sanctuary. More recently, in 2010, both the Sainj and Tirthan Wildlife Sanctuaries were added to GHNP, but will not be formally incorporated until a process known as settlement of rights has occurred. Thus the initiated merger of Sainj and Tirthan Wildlife Sanctuaries with GHNP will be followed by a process of settlement to relocate inhabitants and make the area free of traditional pressures, which may take some time. The total area under Park administration (National Park, Wildlife Sanctuaries and Ecozone) is 1171 sq km, which is together referred to as the Great Himalayan National Park Conservation Area (GHNPCA).
