The present phytosociological study was carried out in Chitral town, Chitral lower Pakistan. The main objective of this research was to determine the vegetation structure and ecological parameters. Data was collected during 2020-2021 in spring and summer season. The quantitative data was collected from 4 monitoring sites by quadrate method. The size of quadrates was 5m² for herbs, 10m² for shrubs and 15m² for trees. The communities Scandix-Stellaria-Nepeta (SSN), Rosa-Rubus-Daphne Community (RRD), Ficus-Elaeagnus-Ailanthus (FEA) and Cannabis-Artemisia-Verbena (CAV) were established in Deningol site. Ranunculus-Mentha-Medicago Community (RMM), Rubus-Rosa-Tamarix (RRT), Robinia-Morus-Ficus (RMF) and Mentha-Cynodon-Conyza (MCC) established in Guwali site, Arenaria-Mentha-Cynodon (AMC), Rubus–Sophora-Tamarix (RST), Elaeagnus-Ailanthus-Morus (EAM), Mentha-Cynodon-Oxalis (MCO) established in Jughhorgol site, Veronica-Plantago-Ranunculus (VPR), Veronica-Plantago-Ranunculus (VPR), Salix-Populus-Elaeagnus (SPE) and Mentha-Plantago-Erigeron (MPE) established in plain areas. Soil analysis was done to determine the physio-chemical properties of soil. The flora was found to be under biotic stress due to anthropogenic activities.
