SPECIES RESPONSE TO ENVIRONMENTAL VARIABLES IN AYUBIA NATIONAL PARK, PAKISTAN USING MULTIVARIATE ANALYSIS
SHEIKH SAEED AHMAD
Abstract: A study was conducted in Ayubia National Park to explore the species response correlation with environmental gradients. Multivariate Analysis was applied to dataset to quantify the vegetation of study area. Vann Dobben circle analysis and T value Biplot was used with the help of Canonical Correspondence Analysis. Two zones were demarcated in Park. Results showed that Species Plantago major and Thlaspi griffthianum had positive and significant response towards environmental variables and few of species showed negative regression coefficient response to environmental variables. Similarly results of Attribute plot show the species response to particular environmental variable. Dominant spp of Zone 1 Hedera nepalensis showed negative association towards organic matter and Rumex nepalensis dominant species of Zone 2 Rumex nepalensis showed positive and significant response to environmental variables.
