OBJECTIVETo determine the present status of plant communities and their possible association with the habitat in Malam Jabba, Swat, Pakistan.

METHODSA study on the phytoecology was conducted in various ecologically important sites of Malam Jabba, Swat, Pakistan from 2002 to 2004. The altitude of these sites ranged from 1 200 m to 3 200 m. Quadrat method was used for evaluation of plants communities and the data on these attributes was converted to relative values. The plant communities were named after 3 leading species with highest importance values. Biological spectrum of the flora based on the life form was prepared by following Raunkiar's life form classes.

RESULTSThe floristic composition and structure of the study area were found to be 200 species belonging to 75 families. Asteraceae, Lamiaceae and Poaceae were important families in the study area. The biological spectrum showed that therophytic and hemicrytophytic life form and micro-nonophyllous leaf sizes were dominant in the area. The air and soil temperatures were decreasing with increasing elevation. Both the air and soil temperatures were relatively higher in south slopes than on the northeast slopes. The vegetation analysis of the area indicated eleven plant communities around the area. The present vegetation is the relics of moist temperate coniferous forest in the area. The communities reflect highly deteriorated conditions. Both the structure and composition of the surrounding vegetation were associated with the types of habitats.

CONCLUSIONSThe conservation of the remaining populations of the reported communities will be best achieved by proper time of sustainable harvesting. It is only possible with the participation of local communities.
