                         forest and secondary succession. To ensure that different 
                         landscapes of {"}Terra firme{"} tropical forest of the Brazilian 
                         Amazon were represented, a test-site was selected in the lower 
                         Tapaj{\'o}s river region (Par{\'a} State). The microwave signals 
                         from the P-band polarimetric images were related to the 
                         aboveground biomass data by statistical regression models 
                         (logarithmic and polynomial functions). In the field survey, 
                         physiognomic and structural aspects of primary forest and regrowth 
                         were collected and afterwards the biomass was estimated using 
                         allometric equations based on dendrometric parameters. As an 
                         example of the potential use of P-band polarimetric images, they 
                         were classified by a contextual classifier (ICM), whose thematic 
                         stratification of land use/land cover was associated with biomass 
                         class intervals for mapping purposes. The main objective of this 
                         P-band experiment is to improve this tool for regional mapping of 
                         Amazon landscape changes, due to the growing rate of land use
