Abstract

Kokarai valley District Swat is rich in plant biodiversity. The plant species varies in their phenological behavior, life form and leaf size spectra. There is no previous record in the area and therefore the study was designed to explore the species diversity, phenology, life form and leaf size spectra of the Kokarai valley that indicates the climate of the area. Phenological behaviour of plant species were recorded from May-August (81.29%) and September-November (18.70%). The dominant life form was therophytes (39.10%) and dominant leaf size spectra was microphyll (45.81%). The therophytic life form indicates the disturbed vegetation while the microphyll leaf spectra indicates that the area are moist temperate and receive a good amount of rain fall. It can be concluded from the study that the phenerophtes should be restored through habitat restoration and the anthropogenic effects on forest should be minimized.
