Goraya and Jeewan S. Jalal ABSTRACT: A floristic survey was conducted in tbe Great Himalayan National Park (GHNP), Himachal Pradesh during in 2010-11. The survey resulted in addition of66 species of Angiosperms belonging to 55 genera under 32 families. These belong to I tree, 13 shrubs, 2 climbers and 50 herbs. The information related to the flowering, altitude, habit and uses are also proVIded. KEYWORDS: Great Himalayan National Park, Floristic Survey, Systematic Enumeration. - • • INTRODUCTION Great Himalayan ational Park (GHNP), lies in the Kullu district of Himachal Pradesh (31 0 38' 28" N to 31 0 5I '58" and 77 0 20" II" E to 77" 45' 52" E). The Park encompasses nearly J ,171 km'. and has an altitudinal range between 1,350-6.000 m. The Park is bounded by Rupi Bhaba Wildlife Sanctuary (WLS) in the East, Pin Valley National Park in the North East and Kunawar WLS in the North Wes\. The South Western fringe of the Park is surrounded by heavy human habitation, cultivation and orchards. It is one of the two ational Parks in the world to support a population of endangered Western Tragopan (Tragopan melanocephalus) and a large number of rare as well as threatened plant species many of which possess medicinal value (Gaston and Garson, 1993). It has only about 17% geographical area under forest vegetation (Negi, 1996). This is due to preponderance of alpine areas beyond tree line such as meadows, rocky and snow bound areas. According to Champion and Seth (1968), the major categories of the vegetation in the area include: Ban Oak forest, Moist-deodar forest, Western Himalayan Mixed Coniferous Forest, Moist Temperate Deciduous Forest, Kharsu Oak Forest, Western Himalayan Upper Oak-Fir Forest, Montane Bamboo Brakes, Himalayan Temperate Parkland, Himalayan Temperate Pasture, Western Himalayan Subalpine Fir Forest, Subalpine Pasture, Singh, G.

The dominant Iree species in the National Park are Abies pindrow, Pinus wallichiana, Cedrus deodara, Quercus leucolrichophora. Q. fionbunda, Q. semecarpijolia, Betula alnoides, B. utilis, Juglans regia and Acer caesium etc. (Singh and Rawat, 1999). The Hin-alayan region of Himachal Pradesh was previously explored by Jain and Bhardawaj (1949), Nair and Pant (1966), Nair (1977), Polunin and Stainton (1984), Chowdhery and Wadhwa, (1984), Aswal and Mehrolra (1994). Singh and Rawat (2000) reponed a total of 832 plant species belonging to 427 genera under 128 families. However, recent collection yielded 66 species as new additions to the flora of GHNP and are enumerated below. Specimens were identified with the help of existing literature (Aswal and Mehrotra, 1994; Polluoin and Stainton, 1984; Deva and Naithani. 1986).
