Explanation:

Nanda Devi Biosphere Reserve, established in 1982 , is a national park situated around the peak of Nanda Devi (7816 m) in the state of Uttarakhand in northern India. The entire park lies at an elevation of more than 3,500 m (11,500 ft) above mean sea level.

The National Park was inscribed a World Heritage Site by UNESCO in 1988. The latter was expanded and renamed to Nanda Devi and Valley of Flowers National Parks in 2005. The National Park is embedded in the 2,236.74 km2 (863.61 sq mi) sized Nanda Devi Biosphere Reserve, which, in turn, is encompassed in the 5,148.57 km2 (1,987.87 sq mi) buffer zone around the Nanda Devi and Valley of Flowers National Parks UNESCO site.
