Description: In the Amazon, the suitable of natural forests is recurring theme in the last years on the world, considering if the same has a huge potential of contribution in products and services. In this context, the reduced impact logging is fundamental in the biodiversity conservation and their forest feedstock sustainable use. Thus, to evaluate a mapping the reduced impact logging in the National forest of Tapajós, Para State, a quantity of information?s and Landsat8 - OLI series merged to orbit-points 227/062 was used to apply in the DETEX methodology (Selective logging Detection), to detect forest exploitation. The results showed significant relationships at use of coherence matrixes of gray levels based on texture characteristics related with remained basal area in fields regarded as reduced impact logging, notably to contrast, entropy, homogeneity and angular second moment texture variables, for the majority of them after the forest exploitation in the area. In addition, the longest filters windows size obtained significant statistical results, aligned with specialized literature about the theme. In this way, is recommended the use of methodology in areas with higher exploitation intensity than used in this study, in order to stablish comparisons and identify levels of intensity in forest exploitation distinct
