The territory consists of 26,000 hectares of forest on the Omerê River[1] and is home to the Kanoê and Akuntsu tribes.
Both tribes were the victims of severe massacres by cattle ranchers in the 1970s and 1980s.
[2][3] As of 2016[update], the Akuntsu number just four individuals and the Rio Omerê Kanoê five.
[4][1] The two tribes are separate peoples speaking mutually unintelligible languages, but are linked by marriage.
[1] Several loggers and cattle ranchers also remain in the territory despite attempts to eject them and continue to pose a threat to its indigenous inhabitants.
