Abstract:
This study provides a broad understanding of vascular plant richness and community structure of mountain grassland (Matri) at Bandipora, Kashmir and links it various environmental variables. Employing a stratified sampling design, six sites were selected wherein vegetation was sampled by placing quadrats (n=210). Elucidating an important effect of topography and anthropic pressure, numerical classification –TWINSPAN segregated the quadrats into seven community types. Contrary to species rich communities which showed an explicit composition and localized distribution, the other communities depicted a vague composition and stretched unevenly between the lower and middle altitudes. Using canonical correspondence analysis (CCA), elevation and disturbance were found as most influencing factors whereas steepness of slope, organic carbon, soil reaction (pH) and soil salinity (electrical conductivity) were other important factors. Indices of
diversity measured at two measurement scales varied differently between communities and at a macro scale (site level) highest values were recorded in least disturbed communities. However, on a micro scale (quadrat level) the indices behaved differently. For effective conservation of these species rich grasslands, acknowledging the local level variability in vegetation structure is all but crucial.
