The study was carried out in four forest types in the year 2006–2007 of Garhwal Himalaya between 800 m to 2600 m asl. Forest types studied for floral diversity were Chir-Pine forest, Pine mixed forest, Temperate broad leaved mixed forest and Dry deciduous mixed forest. However, the floral diversity varied significantly with the forests temperate broad leaved mixed forest exhibited highest tree, shrub and herb density. On the basis of IVI value Pinus roxburghii Sarg. (Chir Pine) reported to be most dominant tree species of the area. Temperate broad leaved mixed forest had high tree and herb diversity, while pine mixed forest exhibited high shrub diversity. The plant biodiversity is utilized for fodder, fuel, timber, construction material and various other non timber forest products (NTFP) by local communities. Anthropogenic disturbance is altering the diversity and distribution of vegetation in these forests, which influence the other ecological and environmental conditions. Therefore, there is an urgent need to conserve and manage these forests for sustainable development of environment and ecology of the region.
