We investigated the floristic composition, phytosociological and regeneration status of Sarkot Van Panchyat (community forest) in Chamoli district of Garhwal Himalaya. A total of 52 plant species of 46 genera and 26 families were recorded, which included 12 trees, 18 shrubs and 22 herb species. Quercus leucotrichophora was dominant tree species in sapling and seedling layers, followed by Lyonia ovalifolia and Rhododendron arboreum. Out of 12 tree species, 7 species in seedling stage and 8 species in sapling stage were recorded in the study area. The 44.41% species in the study area showed good regeneration status, 16.66% species were fairly regenerating, and 8.33% species showed poor regeneration status, while 33% species were not regenerating. Number of individuals from lower girth classes (0--10 cm and 10-30 cm) showed decreasing trend with the increase in size of girth class. Shannon index (H) for trees, shrubs and herbs was recorded as 1.82, 2.24 and 2.41 respectively. Simpsons index (Co) was recorded as 0.21, 0.12 and 0.12 for trees, shrubs and herbs respectively. The forest should be di- vided into compartments for better management purpose and each compartment should be closed for five years to assist regeneration and enrichment planting may also be carried out for sustainable management. 展开更多

Purpose: To evaluate the influence of varying the surgical site on medium to long-term iOP control following unenhanced small flap trabeculectomy (microtrabeculectomy). Methods: A retrospective comparison of IOP control. The first cohort of 17 eyes had flaps centred at 12 o'clock (as part of a prospective trial to study the astigmatic effect of microtrabeculectomy.
