%X The objective of this work was to identify and monitor forest regeneration for a period of eight years after deforestation events occurred in 2001, in the Eastern Amazon region. The study utilizes Landsat Thematic Mapper (TM) images, acquired for scene 224/65 (path/row), for the following dates: 07/06/2000 (Geocover product), 08/02/2001, 08/29/2002, 07/04/2005 (Geocover product) and 08/08/2009. Deforestation data was obtained from the PRODES deforestation mapping program, for the year 2001. The results showed a large and increasing area of forest regeneration, for the area and period of study. The first year after deforestation showed the highest proportion of regeneration (20%), which can be attributed to the known pattern of less intensive land use in the initial years after vegetation removal, associated with stem regrowth and germination from the remaining seed banks. The proportion of regenerated area decreases over the years (through new deforestation of regenerating areas), but still occupies 13% of the deforested area in 2001 by the end of the eight year period (2001-2009). Another important result observed was that from the total area regenerated by 2009, 60% started the recovery process immediately after the 2001 deforestation event, and had no evidence of economic use during the studied period (i.e. no justification for the observed deforestation in the first place). These results emphasize the importance of better understanding and quantifying the role of biophysical and socio-economic factors in the dynamics of forest regeneration in the Amazon, and could help improve carbon emission and biodiversity studies in the region.
