A survey work was carried out to study the invasive and alien flora of Imphal Valley districts of Manipur, during the period of February 2021 to December 2024, 54 invasive alien plant species (IAPs) of 20 families were found in Manipur, among them Fabaceae family recorded highest number of Invasive species. so as to investigate the information of the invasive species of herbs, shrubs, vines, etc. These categories are the successful plant species which are grown and effects the plant diversity i.e. natural flora of Valley district and can withstand in the prevailing environment. In the present scenario of the valley districts of Manipur maximum invasive species recorded i.e. Eupatorium adenophorum followed by Ageratum haustonianum, Mikania micrantha, Lantana camara, Chromolaena odorata Achyranthes aspera, etc. However, some invasive parasites like Cuscuta reflexa and Loranthus scurrula are also interfered the forest flora. Mikania micrantha, Momordica dioica, Dioscorea bulbifera, D. alata, Thunbergia grandiflora, Smilax lanceifolia, Entada phaseoloides, etc. are some of the vines showing green carpeting on the roof of the forest flora is also remarkable. Therefore, necessary steps should be taken up to control the luxuriant growth of the invasive plant species, so, that they do not complete/interfere with the indigenous forest of Manipur.
