The Brazilian forest code of 1965 established native vegetation on the banks of rivers and lakes should be preserved. There was then a need to review and adapt the 1965 law to a new reality, being created the law number 12727, on October 17, 2012 establishing the General rules for the preservation of vegetation in areas of permanent preservation (APPs). Objective this work was to analyze, quantify and map land use conflicts in the APP, under Uraim River basin, located in the municipality of Paragominas, through remote sensing techniques and GIS. To obtain and analyze the data we used Landsat satellite image sensor 8 OLI and TIR (Operational Earth Imager and Infrared thermal Sensor) and Shuttle Radar Topography Mission imagery-SRTM for delimitation of the watershed. Through superimposition of maps the APPs and the classes of use and coverage Earth, the areas of misuse as exposed soil, agriculture/reforestation and pasture, areas of possible shifts. The forest code sets specific rules for the recomposition of these areas. It was found that 207 properties (49%), with Rural Environmental Record (CAR), improper use of the land. One of the main forms of land use in the Uraim River basin highlights the presence of pastureland, occupying about 27%. Uraim River basin, about 29% of the areas destined for permanent preservation are legally employed inappropriately, being occupied mostly by pastures.
