Phytosociological structure of Skyland forests at Wari, Dir Upper, Khyber Pakhtunkhwa, Pakistan

The recent study was carried out to evaluate the Phytodiversity of Skyland forests at tehsil Wari district Dir Upper Khyber Pakhtunkhwa, Pakistan. The field survey was carried out from October 2018 to June 2019. The random stratified sampling design was utilized and collected 89 releves and pile up in the TURBOVEG database. Different community organized from releves by modifying TWINSPAN community categorization analysis. The characteristics of these communities evaluated by (TWINSPAN) Two way indicator species analysis utilizing the host JUICE Program and associated among topographic, edaphic, and environmental changeable through Dentrended Correspondence Analysis (DCA). On the base of edaphic factors five different communities, i.e. Pinus-Berberis community, Pinus-Viburnum community, Abies-Viburnum community, Pinus-Abies community and Abies-Picea community was set up in the Skyland forest. Approximately minimum 10m distance was kept between quadrates of the same formation. The large quantity/ tree cover of plant was estimated through braun-Blanquet Scale and evaluated various factor. Particularly the anthropogenic interruption is the main reason of disturbing of different communities in the study area of Skyland forest.
