Abstract

The present study was conducted to assess the diameter size class (Dbh) distribution of Chalghoza forest in Goharabad District Diamer. Data was collected from six different sites randomly using the PCQ (Point Center Quadrate Method) during July and August 2014. Study revealed that Pinus gerardiana Wall. ex D. Don is the dominant tree species of this forest, while few trees of Juniperus excelsa M.Bieb. and Quercus ilex L.were also found. Different stands possess different densities in the study area. Highest density was recorded 128.4 stems/ha with 16.16m2/ha Basal Area from Stand-1 (Latakhand) while lowest density was observed 57.5stems/ha with 3.98 m2/ha Basal Area from Satnd-6 (Daskil-C). Size class structure shows more or less satisfactory in the entire study area while some gaps are found in early and middle size classes this indicates anthropogenic and other natural disturbances i.e. nuts collection, cutting, grazing, burning, sliding, floods etc.In the light of this study it is concluded that each forest is disturbed, unstable showing varied size distribution. Most of the forests have low seedlings, young trees or they do not show signs of seedling recruitment. The Present practices are threatening and alarming for the future of these forests. Therefore, proper regeneration activities, management skills and conservation plan should be introduced and applied immediately to rehabilitate and save these valuable forests.
