Abstract: Present study aims to assess community structure and regeneration status of Sauni-Binsar sacred natural forest of Kumaun Himalaya (1500 – 2200 m asl). A sum of 30 sampling quadrats of 10 m x 10 m size was placed randomly in the sacred grove. The grove was categorized into three zones- hill base, hill slope and hill top. Circumference at breast height of tree species was measured and their individual number was counted within the sampling quadrats. Various phytosociological attributes such as density, frequency, abundance, Importance Value Index, diversity indices and regeneration status of tree species were analyzed. Tree density ranged from 265 and 375 Ind. ha-1. Cedrus deodara (Roxb.) G. Don was recorded as dominant tree species with the highest IVI of 84.6 at hill base while Quercus leucotrichophora A. Camus was dominant species at hill slope (93.4 IVI) and hill top (125.9 IVI). Shannon-Weaver diversity index (H) ranged from 1.05 to 1.34. In the hill base overgrazing by cattle, pine tree cutting for timber; resin extraction; frequent forest fire in summer was observed that led to no regeneration and forest degradation. Various anthropogenic activities such as overgrazing, resin extraction, fodder and fuel wood collection, forest fire should be controlled by imparting knowledge among local communities regarding sustainable utilization of forest resources with the help of forest department.
