EVALUATION OF ECOLOGICAL ASPECTS OF ROADSIDE VEGETATION AROUND HAVALIAN CITY USING MULTIVARIATE TECHNIQUES
Abstract
A survey of Abbottabad roadsides vegetation and soil was undertaken. The floristic data were analyzed by using multivariate analysis techniques i.e. Detrended Correspondence Analysis (DCA) and Canonical Correspondence Analysis (CCA). A total of 63 plant species and 5 major communities were recognized along 5 major roadsides as demarcated by DCA and CCA. The study also investigated the vegetation structure and its relationships to selected environmental factors. This relationship was determined by CANOCO analysis. The most important factors influencing the roadside vegetation were found to be lead and copper, and zinc to some extent. This study provides the basic information to preserve and improve the roadside vegetation, for reservation of native flora.
