anglais. Frequent oil spills in the Niger Delta have severely influenced the environment in oil production and transportation areas. Vegetation degradation is one of the remarkable results of oil spills in the region. Hence, GIS was used to build an Oil Spill Risk Assessment Model for Vegetation (OSRAMV) in the southern part of the Rivers state, mainly in the Bonny district to define areas under high levels of oil spill hazard and vegetation areas under high oil spill risk. Oil Spill Hazard Model (OSHM) was examined to ensure its accuracy by recorded oil spill impacted areas
