In the last 25 years, that land has been continuously trespassed by illegal loggers a threat not only to the forest itself, but to the Indians, victims of life threats, attempts and murders. Tired of waiting for the Brazilian government to take action even after several reports, the Kaapor people developed an independent project to monitor and cast out trespassers from their land. After a request for help, Greenpeace joined the Kaapor to boost that surveillance plan with the aid of technology, like trackers and trap cams, which could be installed by the Kaapor themselves. Fronteira da Terra Indígena Alto Turiaçu, do povo Kaapor, com o avanço do desmatamento em áreas vizinhas, no estado do Maranhão. Distribuída em cerca de 530 mil hectares, a Terra Indígena Alto Turiaçu, do povo Kaapor, representa uma das últimas extensões de floresta amazônica no Maranhão. Nos últimos 25 anos, esse território tem sido continuamente invadido por madeireiros ilegais, que representam não apenas uma ameaça à floresta, mas também aos índios, vítimas frequentes de ameaças, assassinatos e atentados contra as suas lideranças. Cansados de esperar por uma atitude das autoridades brasileiras depois de inúmeras denúncias, os Kaapor desenvolveram um projeto independente de monitoramento para expulsar os invasores de suas terras. Atendendo a um pedido de ajuda desse povo o Greenpeace auxiliou o povo Kaapor a agregar a esse sistema de autovigilância o uso de tecnologias, como rastreadores e trap cams, que poderiam ser implementadas pelos próprios indígenas e fornecer evidências mais contundentes e pressionar ainda mais o governo brasileiro.
