In 2012, the Tapajós National Forest lost part of its territory. Something unprecedented at that moment for a National Forest in Amazon. Founded in 1974, the Tapajós National Forest suffered from several territorial conflicts right from the start. These conflicts arose when many families immigrated to the region during the construction of the BR-163 and along with this immigration, villages were created within the limits of the conservation unit. Within these villages emerged the communities of São Jorge, Santa Clara, Nossa Senhora de Nazaré and Nova Vida. Some residents of these communities obtained, through Incra, definitive land titles within the domains of the National Forest. From this land titling, there was a territorial overlap between the lands of the Tapajós National Forest destined for preservation and the lands titled by Incra used for agrarian purposes. A long conflicting process began with the territorial overlapping of land between the Tapajós National Forest and the residents of the communities of São Jorge, Nossa Senhora de Nazaré, Santa Clara and Nova Vida. Over almost 40 years, residents of these communities and emissaries from IBDF, Ibama and Chico Mendes Institute for Biodiversity Conservation (ICMBio) representing the Tapajós National Forest searched for a common denominator, which only occurred in 2012 through the process of dismemberment the communities of São Jorge, Santa Clara, Nossa Senhora de Nazaré e Nova Vida. The present research understands the reasons that led to the delay in this process of disaffection. We used a bibliographic collection, interviews and analysis of official documents to conclude the result. And the result for the delay in the removal process was the lack of articulation between the federal management bodies and the communities.Because, over 38 years, countless decisions were decided and then undone or postponed, thus hindering a final resolution.
