Abstract : Monitoring of vegetation cover is a very important indicator for understanding the effects of human activities on the environment; the findings are used to establish links between policy decisions, regulatory actions, and subsequent land-use activities. The main aim of this study is to monitor the locations and distributions of land-cover changes from (1986, 1987, 1988, 1990) to (2000, 2001) in Hail, Saudi Arabia. Image processing was used to calculate normalized difference vegetation index (NDVI) from satellite data. This study used five Thematic Mapper (TM) satellite scenes from Landsat 5, and five Enhanced Thematic Mapper (ETM) images from Landsat 7. The results show a slight change in the vegetation cover for Hail. The total area of vegetation cover in the years 2000 and 2001 was 688 km², compared with 607 km² at the start of the study period. The additional vegetation cover (135 km²) represents an increase of 22%, and the areas of decreased vegetation cover (54 km²) represent a loss of 9%. Overall, 69% (418 km²) of the study area shows unchanged vegetation cover.
