Ka'apor people set up trap cameras to monitor the indigenous territory in areas used by illegal loggers. In late August 2015, Ka'apor leaders from the Alto Turiacu Indigenous Land, in the North of Maranhão state, started to integrate the use of technology in their autonomous activities of monitoring and protecting their traditional territory, in partnership with Greenpeace. Among the suggested tools adopted by the Ka'apor people are: more accurate maps; trap cameras aimed to document the invasion of logging trucks; and satellite trackers to monitor the routes of logging trucks in and out of the Alto Turiacu Indigenous land.
