 Mimosa invisa Mart, a semi-perennial leguminous weed is a threat to forest ecosystems, agricultural lands and pastures. Research to reduce the problems caused by this weed is a priority in many agricultural institutions. The above-ground weed floral and seedbank of Minvisa infested fields in fifteen Local Government Areas ( L.G.A.s) of Edo State was assessed in 2012 .The aboveground weed flora was assessed in randomly thrown I m x I m quadrats iii each field which the direct seed germination technique in the greenhouse was used to assess the seedbank density and floral composition . Orihonmwom had the highest above-ground relative weed density(74.4%) while Akoko Edo L.G.A had the largest weed seedbank size which was positivly associated with increasing soil organic carbon and nitrogen content. Species diversity was highest in Esan North L.G.A in above — ground floral while Igueben L.G.A was highest in weed species diversity in the seedbank. M. invisa density tended to be higher in fields with moderate phosphrous, organic carbon, nitrogen, and calcium in the soil. Seed population of other species associated with M invisce was found to he highest in Ovia Southeast L.G.A . C. rolundus, P. ainarus, M. villous, P. pedicellalum were found to be next threat when M. invisa was controlled.
