  2. 2. Ecosystem services of Himalayan vegetation “components of nature used for human wellbeing” (Boyd and Banzhaf, 2006) Himalaya worlds youngest and highest mountain range with fastest uplift rate have 7,500 - 10,000 species of ethnobotanical uses (Pei, 1998)

  5. 5. Data Analysis (First year Field Work) 1296 releves/quadrats from 144 sample sites being analysed with 5 environmental variables through; I. EXCEL 2007, II. PC-ORD version 5 and III. CANOCO version 4.5
  6. 6. EXCEL 2007Was used to calculate; Absolute and relative values of quantitative and qualitative attributes (Presence/absence, Density, Cover & Frequency) of plants Species and environmental data matrices, according to the CANOCO and PC-ORD requirements Constancy, % constancy and fidelity of species for a specific community Graphic presentations of basic climatic, species and environmental data
