摘要: Himalayan broad-leaved forests are mainly dominated by oak (Quercus spp.) species. Oak species with other tree provide numerous ecosystem services and serve as lifeline for local inhabitants. Overall diversity their status in different viz., Quercus leucotrichophora (1500-2200 m), Q. floribunda (2201-2700 m) semecarpifolia (2701-3300 were studied Garhwal, Himalaya. A total of 54 (40 genera) leucotrichophora, 43 (30 23 (16 recorded. Lauraceae was the dominant family (6 8 respectively), while Ericaceae (3 species) forests. Pinaceae Taxaceae only two gymnospermic represented Pinus roxburghii at low, Abies pinrow mid, spectabilis Taxus wallichiana higher elevational There no significant variation ( p=0.8) between overall density which ranges from 337±51 individual/ha to 433±92 The seedling has p=0.01) where highest recorded (1981 individual/ha) lowest (348 individual/ha). Total Basal Area (TBA) reported (88.06 m 2 /ha) (110.5 than those earlier region, basal area (90.16 comparable western
