As a result, they store more dicotyledons, 97 monocotyledons and four species of gymnosperms than 15% of the terrestrial carbon (Holdgate 1999) and belonging to 85 families collected from Nohra Forest Block of Churdhar Wildlife Sanctuary, District Sirmaur, Himachal Pradesh are reported as also serve as a tool for containing future exceptional additions to the district. This includes 13 threatened species under loss of habitat. Accordingly, it has now been realized different Red List assessments, both global and regional and 35 species are endemic to western Himalaya. that inventorisation of plants occurring in such areas is absolutely necessary and so are the initiatives from Keywords: Additions, Churdhar, flora, Himachal Pradesh, protected the Ministry of Environment, Forests, & Climate Change, area, Sirmaur.

Studies undertaken here in the elements in different altitudinal zonations of the recent past include the works of Gupta (1998) and sanctuary, periodic field trips were undertaken starting Kumar (2004) but they recorded only the medicinal flora of the sanctuary. The first published account on the flora of Sirmaur District is of Kaur & Sharma (2004), wherein they reported 911 species belonging to 544 genera under 139 families again only touching the boundaries of the sanctuary and its core area. The present study had been carried out systematically for assessing the floristic wealth of Churdhar Wildlife Sanctuary including its rich potential of herbal medicinal plants. However, in this paper only Nohra Block of the sanctuary and the additions to the flora of district Sirmaur have been highlighted. Study Area V Churdhar Wildlife Sanctuary—one of the important protected areas of the Himalayan region—is located in the Trans-Giri hill ranges of Sirmaur and Shimla districts in the state of Himachal Pradesh. The sanctuary which falls around Chur Peak (3,647m), one of the Shivalik’s highest summits in sub-tropical Himalaya, was established in the year 1985 with a view to preserve the biological wealth and floral diversity in the Panchmuda Range of Churdhar. The sanctuary comprises an approximate area of 66.70km2 with wide altitudinal ranges varying from approximately 1900–3647m and lies in between 30048’37”–30054’39”N & 77023’32”– 0 77 29’49’’E. From a management point of view, the Figure 1.

The voucher the dominant 10 families are Poaceae followed by specimens thus collected, were identified using local Asteraceae, Orchidaceae, Cyperaceae, Ranunculaceae, Floras (Chowdhery & Wadhwa 1984; Polunin & Stainton Scrophulariaceae, Apiaceae, Papilionoideae, Rosaceae 1984; Collett 1902; Kaur & Sharma 2004) and species and Caprifoliaceae which contribute 45% of the total indentity was further confirmed by comparing the collections (Fig. 2). Though the habit of plants are authentic specimens housed in DD Herbarium of Forest exhibited in all life forms, herbaceous habit was found Research Institute and Herbarium of Botanical Survey of to be the most dominant among others, followed by India, Dehra Dun. Families of the specimens are arranged shrubs, trees, climbers and others as shown in Fig. 3. following Bentham and Hooker’s classification and Out of the total 352 species, 35 taxa, viz., Acer under each family, species were arranged alphabetically acuminatum, A. caesium, Aconitum laeve, Aconogonum with their recent botanical name, habit, flowering rumicifolium, Arenaria festucoides, Bupleurum season, forest area and altitudinal zonations.
