Tree regeneration status of sacred and protected landscapes in Garhwal Himalaya, India.

摘要

Global and national recognition of Garhwal Himalaya as sacred and protected land has not spurred conservationists to investigate these sacred and protected forests and recognize their importance at large scales. Little is known about the role of sacred conserved forests in influencing the regeneration of species in Garhwal Himalaya. In the present study we investigated the regeneration status of tree species in five sacred and protected forests of Garhwal Himalaya. Seedling and sapling density was used as an indicator of regeneration status of present species. A total of 47 species of trees were recorded from five sacred and protected forests, among which only 7 species showed either good or fair regeneration in all the five sites, whereas a majority (17 species) showed either poor or no regeneration. The dominant species were Quercus spp., Rhododendron arboreum, Myrica esculenta, and Lyonia ovalifolia. Sapling density ranged from 8.84 to 15.2 saplings/100 m2 and seedling density ranged from 11.36 to 18.74 seedlings/100 m2 in different study sites. Our study showed the regeneration status of lesser (auxiliary) species in the forests was low as compared to dominant ones. Girth class distribution of individuals showed a reverse J-shaped curve for all the species at all the sites.
