Description Hydrocarbons that seep from the earth’s sub-surface often affect the environment, soil, rocks and stress growing vegetation. In this study, natural hydrocarbon seepage was mapped in Ugwueme, Awgu Local Government Area of Enugu State, Nigeria using Remote Sensing and GIStechniques with the aim of detecting vegetation stress changes over a period of time. It was conducted using Landsat 7 ETM+ 1996, Landsat 7 ETM+ 2006 and Landsat 8 OLI/TIRS 2016.The global positioning system and the topographical maps of scale 1:100,000 were utilized for ground verification. Results revealed that the category of severely stressed vegetation roseprogressively from 40.25% in 1996 to 54.73% in 2006 and then to 60.82% in 2016, while the category of less stressed vegetation reduced from 59.75% in 1996 to 45.27% in 2006 and then to39.18% in 2016. There is an overall increase in the vegetation class cover classified as severely stressed, proving that remote sensing and GIS is a valuable tool for mapping hydrocarbonseepage areas. Thus, afforestation, re-afforestation and good land practices are recommended as preventive and remedial measures in the study area.
