Abstract
The objective of present study was to assess the impact of human induced anthropogenic pressure on regeneration and Importance Value Index of woody species in the study area. The study was carried out in Katerniaghat Wildlife Sanctuary having an area of 400km2 located in Bahraich district off Uttar Pradesh, India. The latitude and longitude of study area is 28ᴼ 06҆ N & 28ᴼ 24҆ N latitudes and 81ᴼ 02҆ E & 81ᴼ 19҆ E longitude. The sanctuary has moist deciduous type of forest and enriched with wide variety of flora and fauna. For methodology, a reconnaissance survey was carried out and area was stratified on the basis of presence of anthropogenic disturbance indicators into high, medium and low disturbed sites. Circular plot method was used for used for tree and regenerative species in each stratified sites. For data analysis, Importance value Index of woody species, density and Sorenson’s similarity coefficient was calculated. The overall highest IVI is of Lannea grandis (75.45) in the study area. In low disturbed site, the highest is of Scleichera oleosa (28.52). The sapling and seedling density of Mallotus phillipinensis was found to be highest in low disturbed site (419.46/ha and 549.3/ha respectively). The Sorenson’s similarity coefficient of seedling was found to be highest (46.67%) across high-medium disturbed site compared to tree and sapling layer. The family Fabaceae was represented by seedling layer in the study area with highest proportion (26.66%) compared with tree and sapling layer. In the present study, urgent conservation initiatives are required for species showing lower IVI in highest and least disturbed site. The rare regenerative species having lower densities also needs utmost consideration.
