摘要：The phytosociological survey of moist temperate forests of Lasdana, District Bagh Azad Kashmir was conducted during 2016-2017. Quadrat method was used for sampling vegetation in three layers viz herbs, shrubs and tree. The flora comprised of 128 plant species distributed among 105 genera and 46 families. Elven plant communities were recognized on the basis of importance value. They were grouped in to three plant association using cluster analysis and Detrended correspondence analysis viz. Gallium-Adiantum-Frageria association, Pinus-Sarcococca-Poa association and Abies-Vibernum-Cynodon association. Diversity was high at middle elevation and low at upper and lower altitude. Richness was negatively correlated with altitude. Whereas, evenness and equitability has little or no influence of altitude. Canonical Correspondence Analysis (CCA) revealed that altitude, phosphorous, pH and electrical conductivity play major role in defining distribution pattern of plant communities and species. The investigated forests are disturbed with poor regeneration potential and low species diversity. Therefore, immediate conservation measures along with participation of local community are recommended.
