The JERS-1 backscatter temporal behavior of some land cover types in Tapajos National Forest is analyzed. The following land cover types were investigated: bare soil, agriculture, pasture, secondary forest from one to 23 years old and primary forest. The differences in backscatter of these land cover types are discussed, based on the analysis of previous land use and human impacts such as fires and selective logging.
