History of vegetation analysis and description is discussed. Vegetation analysis in Pakistan may be divided into 5 periods i.e. observational, quantitative Phytosociological, multivariate analysis (ordination), population dynamics and modem multivariate and numerical techniques. It is observed that period of observational analysis of the vegetation lasts until around 1970; however in Karachi U ...

The present study is based on the examination of quantitative vegetation description of moist temperate conifer forests of Himalayan region of Pakistan. Forty one stands at five different locations from Himalayan Region of Pakistan were chosen for the study. The underlying group in the vegetation was exposed using Ward's cluster analysis. The three groups derived from cluster analysis were sup ...

The present study deals with the phytosociological analysis of the selected graveyards of Upper Swat. Seven conserved graveyards were sampled and various ecological attributes were obtained. Based on IVI seven different communities were identified, representing 54 families and 95 species. Out of these 95 species 50 species were herbs, 25 shrubs and 20 were trees respectively. The findings show ...

Phytosociological study was conducted in pine forests throughout district Dir. Point centered quadrate method was used for sampling and twenty five pine forests were sampled between elevation ranges 1400-2672 meters above mean sea level. Phytosociological attributes (frequency, density, basal area, importance value) and absolute values (Density per ha and Basal area m-2 per ha) were calculated ...

The present study reports the dendroseismological potential of pine tree species including Pinus wallichiana. Picea smithiana, Abies pindrow, Pinus roxburghii, Cedrus deodara. A total of 261 cores from 213 trees were sampled from different areas of Azad Jammu and Kashmir. These samples were processed following the standard dendrochronological techniques described by Stockes & Smiley (1965). Th ...
