Abstract

The study was conducted to find out impact of anthropogenic pressure on the biomass and productivity of forest floor vegetation in a submontane forest of Tarai of Kumaun Himalaya adjacent to Kashipur. The vegetation was studied at monthly intervals from April 2007 to April 2008 at two selected sites, site I and site II. Aboveground green biomass, aboveground dead biomass, belowground biomass and litter biomass were higher at site II (Gulzarpur forest). Similarly aboveground primary production, belowground production and total net primary production were recorded higher at site II, but litter production was higher at site I (Jogipura forest). Aboveground and belowground turn over was maximum recorded at site II but litter turn over was maximum recorded at site I. Based on the study, it is concluded that the forest at site I which suffer from anthropogenic pressure have low biomass and net primary productivity.

Abstract

The soil samples of two forest types i.e., mixed deciduous type and plantation type were analysed for their physical and chemical properties at Tarai and Bhawar regions of Tarai West Forest Division, Ramnagar, Uttarakhand. Soil colour varied from grayish brown to light brownish gray and soil texture varied from silty clay loam to sandy loam. The result of the present study shows that the higher per cent of water holding capacity, pH, organic carbon, organic matter, total nitrogen, available potassium and available phosphorus was higher in mixed deciduous type forest than in plantation type forest. The pH indicate that the soil of both forest types were acidic in nature.
