SHEIKH SAEED AHMAD* AND TAHIRA YASMIN
Abstract
A survey of natural vegetation along Hanna Lake, Baluchistan was undertaken. The study was conducted with in two distinct zones for clear communities’ demarcation. The vegetation data was analyzed by TWINSPAN and DECORANA, to classify the vegetation into plant communities. Thirty eight species belonging to 16 families were recorded from 20 quadrats of Zone 1 and 36 species belonging to 16 families were recorded from 20 quadrats of Zone 2. Two major and four sub-communities were demarcated by TWINSPAN in both zones. DCA results showed three distinct plant communities in both Zones. Mostly the TWINSPAN and DCA results were similar and the plant communities classified by TWINSPAN were confirmed by DCA. The study provided base line data, information and importance of native plant communities.
