This study aimed to investigate the composition of municipal solid waste (MSW) disposed in the different dumping sites and their impacts on soil and plants in District Bajaur. The collected data showed that the solid wastes disposed in Khar and Inayat Killi have a high content of organic matter. The paper's content in the solid waste was found low in the Sadiq Abad site as compared to other sites of the research area.  The plastic, glasses, clothes and metals were found in almost similar quantity in all the monitoring sites. The solid waste dumping site had a unique flora of 46 species belonging to 22 families. The family Asteraceae was found dominant with 9 species followed by Solanaceae with 5 species, Poaceae with 4 species, Amaranthaceae Brassicaceae and Euphorbiaceae with 3 species each. The rest of the families had one or two species. The habit-wise distribution of the flora was led by herbs with 44 species. Theophytes (35 species) and hemicryptophytes (4 species) dominated the life form spectrum. The seasonal availability reveals that the spring (42 species) and summer (41 species) seasons had the maximum number of species. The impacts of MSW on plant life showed that the plants on or near the dumping site were in the worst condition of their health.
