 To this last end, ACT conducts an annual indigenous park ranger training program certified by the International Ranger Federation.Areas ethnographically mapped by ACT, in collaboration with local tribes, include Brazil's 2,800,000-hectare Xingu Indigenous Reserve, its 248,000-hectare Suruí Indigenous Reserve, and its 4,000,000-hectare Tumucumaque Indigenous Reserve.The Suruí Reserve mapping was facilitated by technical assistance from Google Earth Outreach, which also trained the tribe in remote monitoring.
