Vegetation analysis and winter season carrying capacity of sub-tropical,sub humid rangelands of Dhrabi watershed,Pakistan

Quantitative vegetation assessment of dhrabi watershed chakwal,pakistan was conducted to determine the productive potential and carrying capacity during winter 2008-09. twelve sites of watershed were selected on the basis of variation in altitude using stratified sampling with line transect method. overall,average grasses cover was 64.09% in the area with the highest value (73.41%) in the upper zone and lowest (56.33%) in the lower zone. average trees and shrubs cover was 19.74% with highest value (29.72%) in the middle zone followed by upper (21.54%) and lower zone (7.95%). the range was found in good condition with overall carrying capacity of 2.41 ha/au/4month. the main dominating plant species found in the area were heteropogon contortus (sariala ghaas),cynodon dactylon (khabbal ghaas),desmostachya bipinnata (dab ghaas) and acacia modesta (phulai).
