Dhanpal Singh Chauhan, Pankaj Lal and Dinesh Singh

The present studied was carried out in four districts of Garhwal Himalaya. Survey and sampling of vegetation were completed used standard ecological method with aim to study of plant composition, population structure and regeneration at different site in the four districts viz. Pauri, Rudrapryag, Tehri and Chamoli of Garhwal Himalaya. Each district represents two sites, falls an altitude in Pauri (1850-2070 m), Rudrapryag (1775-2147 m), Tehri (1938–2459 m) and Chamoli (1711–1960 m). Among the altitudes over all range is (1711-2459 m) altitudes in all eight sites, total 16 tree species has been recorded. Total tree density varies from 670-1510 Ind ha^-1, total seedling density from 220-1540 Ind ha^-1 and total sapling density 165-1300 Ind ha^-1 was recorded in all sites among the attitudes. Species diversity (H^-) was observed between 0.12-0.19 for trees, 0.04-0.40 for seedling and 0.07-0.15 for sapling in all sites among the attitudes.
