摘要：The present study was carried out in two forest types in Dhundsir Gad Watershed of Garhwal Himalaya, Uttarakhand (India) to assess regeneration status of tree species. The overall regeneration status was fairly good in both forest types, although regeneration was better at the Anogeissus latifolius Forest with its high seedling (1,190 per ha) and saplings density (860 per ha), than the Pinus roxburghii Forest where the number of seedlings was 1,080 per ha and the number of saplings 600 per ha. Diameter class distribution of tree species in both forest types showed the highest number of individuals concentrated in the lower diameter classes than the higher diameter classes, suggesting that they have good regeneration potential. The most of the tree species was found with good regeneration in the both forests. Species such as Acacia catechu, Aegle marmelos, Anogeissus latifolius, Bauhinia variegata, Lannea coromandelica, Ougeinia oojeinensis, Phyllanthus emblica and Syzygium cumini showed good regeneration, while the species Engelhardia spicata, Erythrina variegata, Pinus roxburghii and Terminalia alata exhibited fair regeneration in the study area.
