Vegetation classification in Ayubia National Park, Pakistan using ordination methods

摘要

Present study was conducted in Ayubia National Park which was declared as a protected/National Park. The study classified the species abundance and its distribution. A total of 59 species that belonged to 32 families were recorded. Overall two major communities were identified using TWINSPAN. Major group 1 comprised of Hedera nepalensis and Adiantum caudatum and major group 2 comprised of Plantago major and Rumex nepalensis. The species data was subjected to Nonmetric Multidimensional Scaling, specially used for extracting nonlinear gradients in species composition. The overall data was analyzed by Monte-Carlo test to access the stress in relation to dimensionality. Furthermore overlay matrix was carried out for only two dominant species that is Adiantum caudatum and Hedera nepalensis to show a relationship in relation to score on a particular axis. The study identifies and highlights the critical need for the protection and conservation of localative flora in Ayubia National Park.
