Community structure of dandachali forest of tehri forest divison, north-west himalaya

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 roxburghiiQuercus leucotrichophora mixed, Pinus roxburghii, Pinus roxburghiiRhododendron arboreum mixed, Cedrus deodaraPinus wallichiana mixed, Cedrus deodaraRhododendron arboreum mixed and Rhododendron arboreumQuercus leucotrichophora mixed, have been recorded in 16 sites between 14822200 m asl. Among the communities, total tree density ranged from 263.34-1493.33 Ind ha, TBA 260.2310.7 m ha and total shrub density 488.34250 Ind ha. Species diversity (H’) for trees ranged from 0.58-1.89. Concentration of dominance (cd) of trees ranged from 0.20-0.76.
