Phytosociological attributes of different plant communities of Pir Chinasi Hills of Azad Jammu and Kashmir [Pakistan]

Abstract

The vegetation of Pir Chinasi hills has been protected from biotic interference and can be used as a typical example of natural vegetation showing vigorous growth. Environmental factor such as climate, soil condition, temperature, humidity, rain fall, wind and biotic factor were studied in relation to vegetation structure. The soil varied from heavy loam to clay and clay loam with pH of 5.4-7.0, electrical conductivity varied from 0.02-1.48 dS m, Phosphorus 5-25 ppm, potassium100-500 ppm, 3.36.7% organic matter and 40-80% saturation. On the whole13 plant communities were recognized and a total of 77 species were recorded. It was found that chemical contents of soil played a significant role in giving particular shape to these communities.
