VEGETATION CLASSIFICATION IN AYUBIA NATIONAL PARK, PAKISTAN USING ORDINATION METHODS SHEIKH SAEED* AHMAD AND QURATULANN Department of Environmental Sciences, Fatima Jinnah Women University Rawalpindi, Pakistan Abstract 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 local/native flora in Ayubia National Park. Introduction Martı nez et al., 2002), names assumed to both group to manufacture an inordinate amount of material for an The study highlighted the Ayubia National Park as the easier clarification (Santos et al., 2006). solitary moist temperate forest in Pakistan with a high Ahmad (2009) studied the relation of herbaceous diversity of susceptible plant and animal species. It is vegetation with edaphic dynamics of Margalla Hills located at North of Islamabad in the Galliat Hills (Khyber National Park, Islamabad, using TWINSPAN and DCA.

The sub-communities (divided by TWINSPAN) as of 397 geographical location of the park is 330-52’ N- 730-90’ E. quadrats and 227 plant classes were chronicled. The study The aim of this research was to quantify the was obliging for implementation and preservation vegetation in Ayubia National Park using ordination planning and for the development of road sides. Enright et techniques and to quantify the floristics. Study will create al., (2005) conducted a study on desert flora and consciousness to protect natural vegetation. Increase in vegetation-environment relationships in Kirthar National population and stipulate of land for infrastructure has Park, Sindh, Pakistan. Analysis of the desert flora of resulted in destruction of existing vegetation and Kirthar National Park, Pakistan, verified 466 plant species inadequate planting sites (Jim, 2000); which has in 372 sample quadrats. Cataloguing was done by pretentious of the quality of ecological environment and TWINSPAN and ordination. Khouly & Dawood (2006) human health (Jackson, 2003). Over the past several carried out study in Sied National Park in Saudi Arabia decades, an urban collapse has resulted in trouncing of using TWINSPAN. The study appraises the species natural vegetation and fragmentation of open green spaces diversity of the flora inside the park associating with the which facilitates environmental and ecological functions vegetation freestanding the park. This study documented (Benedict & Mc Mahon, 2002). Floristic species the occurrence 21 families are verified in the said Park, composition in cities is intimately related with human while 17 families were recorded outside the park. activities (Hope et al., 2003). Ayubia National Park of Pakistan is an amazing area due to its value as well as Methodology: For the clear communities demarcation accepted exquisiteness wherever the scenery, vegetation study area along Ayubia national park was divided into also fauna are sheltered, preserved in a natural state along two zones. Zone 1 of study area was located about 1 m with its use for amusement, education and research to the from the walking track. Twenty quadrats were laid down public. There are 25 national parks in Pakistan and Azad along both sides (10 quadrats on each side).Quadrat Jammu and Kashmir out of which 14 casing an overall method was used for the collection of vegetation data. district of 2.8 million ha. 0.20 Million ha is the standard Quadrat size of 1 × 1m2 was selected because mostly dimension of protected area (Rivard et al., herbs and shrubs were present in the area Within each 2000).Ordination and taxonomy are operational practices quadrat, cover values of plants were recorded by visual for multivariate analyses of community edifice in estimation according to Domin Cover Scale (Kent & vegetation ecology (Zhang, 2004).
