Deep in the Amazon forest thousands of people still live in relative isolation from the rest of the world.
In a recent press release, the Brazilian government confirmed the existence of another uncontacted tribe of about 200 people living in the Vale do Javari reservation. The reservation, located near the Peruvian border, is roughly the size of Portugal. At least another 14 uncontacted tribes, with a total population of about 2000 individuals, call the area home.
The newly observed group lives in four large thatch-roofed buildings and grows corn, bananas, peanuts and other crops.
Brazil's National Indian Foundation, known by its Portuguese acronym FUNAI, first noticed clearings in the forest using satellite maps. But it wasn't until April that an airplane expedition was able to confirm the tribe's existence.
"The work of identifying and protecting isolated groups is part of Brazilian public policy," said the FUNAI coordinator for Vale do Javari, Fabricio Amorim, in a statement to the Associated Press. "To confirm something like this takes years of methodical work."
