Floristic composition and vegetation sturucture of Malam Jabba valley, District Swat
Abstract
Floristic composition and vegetation structure of Malam Jabba Valley was studied during 2012-13. Vegetation structure was analyzed by using Quadrate method. The study area contains 102 plant species belonging to 39 families. Out of which the most dominant family is Asteraceae which have 7 species followed by Rosaceae possessing 6 species. A total of eight plant Communities were recognized from the results by applying Two Way Indicator Species Analysis (TWINSPAN) classification. In DCA unconstrained analyses the total variation were 9.86. The Eigen value for Axis 1, 2 and 3 were 0.8276, 0.6442 and 0.5295 respectively. Result of CCA ordination clearly indicated that environmental variables has a great impact on the distribution of vegetation. The maximum environmental variable strength were recorded for Nitrogen followed by lime. The minimum environmental variable strength were recorded for organic matter followed by Potassium.
