Abstract. The objective of this study was the historical monitoring of forest clearance in the region of the "Espinal" (thorn forest) in northeastern of Entre Ríos Province. Monitoring changes in land use and cover is needed for government policies of conservation and management of natural resources. The study area was the northern of Entre Rios province. The typical vegetation is Espinal thorn forest, subjected to selective logging for extensive livestock ranching and now subjected to agriculture too. The methodology use Landsat imagery and change detection technique to form a package with spectral bands and a band of intensity of changes. On this package we applied the technique "Image segmentation by region growing with manual seeding". Then, the thematic aggregation based on visual interpretation was made. Finally, the map of historical clearance was obtained by Boolean operations between annual thematic masks. The segmentation of images combined with successive masking achieved good results for historical monitoring of forest clearing.
