dc.description.abstractABSTRACT The present investigation entitled “Studies on distribution pattern of Taxus wallichiana Zucc. in relation to altitude and aspect in Himalayan moist temperate forest of Rohru Forest Division in Himachal Pradesh” was carried out in Dodra Kwar and Khashdhar forest ranges in Rohru Forst Division during the year 2017-19 with the aim to study the floristic composition, phytosociology, regeneration status and soil physio-chemical properties along different altitudinal range and aspects. The study area was divided into three elevation zones, E1=2600-2800 m, E2 =2800-3000 m and E3 = 3000-3200 m in northern and southern aspect. Phytosociological parameters of trees, shrubs and herbaceous vegetation in each elevation and aspect were studied by laying down three sample plots of 0.1 ha for trees, within it five sub-quadrates of size 5m×5m for shrubs and 1m ×1 m for herbs were laid out. Composition, density (trees or ind. ha-1), basal area (m2ha-1) of different vegetation layer for tree, shrub and herb layers were analyzed. The data were analyzed by using factorial RBD factorial. Both forest ranges were comprised of 44 plant species. Maximum density and basal area of trees were present at mid elevation of 2800-3000 m in northern aspect while, shrubs and herbaceous vegetation density and basal area followed decreasing trend along increasing elevation and northern aspect as compared to southern aspect. The regeneration study conducted to know the status of natural regeneration indicated maximum regeneration success (27.77 %) at elevation 2800-3000 m on northern aspect in Dodra Kwar range for Taxus wallichiana. Soil organic carbon, available N were recorded highest on northern aspect while soil bulk density, available P, available K and pH recorded highest on southern aspect. Along the elevation, soil organic carbon, bulk density, available N, K, pH, were decreasing while available P and EC wereincreasing.en_US
