Abstract: The present investigation was conducted in Dandachali forest of Tehri Forest Division, North-Western part of Himalaya. Surveys and sampling of the vegetation were done using standard ecological assessment methods with an aim to study plant species composition and natural regeneration status at community level. Forty seven woody species (17 trees) belonging to 12 families and 15 genera, and 6 forest communities viz., Pinus roxburghii- Quercus leucotrichophora mixed, Pinus roxburghii, Pinus roxburghii- Rhododendron arboreum mixed, Cedrus deodara- Pinus wallichiana mixed, Cedrus deodara- Rhododendron arboreum mixedand Rhododendron arboreum- Quercus leucotrichophora mixed, have been recorded in 16 sites between 1482- 2200 m asl. Among the communities, total tree density ranged from 263.34-1493.33 Ind ha-1, TBA 260.2- 310.7 m2 ha-1 and total shrub density 488.3- 4250 Ind ha-1. Species diversity (H’) for trees ranged from 0.58-1.89. Concentration of dominance (cd) of trees ranged from 0.20-0.76.
Keywords: Survey, Tehri Forest Division, North-West Himalya
