Even with the rapid destruction of the rain forest that we all here about, there are still vast tracks of virgin rain forest left, and reports of uncontacted tribals. Some of these tribes have chosen to remain hidden as any contact they have had with outsiders has been violent. There is continuning encroachment on their traditional lands by the timber industry, and miners, and by others.
Javari Valley: According to National Geogrphic, the Javari valley on the border with Peru has the highest concentration of uncontacted people in the Amazon. Reuters reports that their are at least three unknown tribes in the valley. Nobody is really sure how many uncontacted individuals there are. In 1997, Brazil stated that it has plans to set aside 20.5 million acres as an Indian reserve. There has been, of course, widespread opposition by many Brazilians who believe that the land should be available to all citizens, and who don't understand why so much land should be set aside for so few.

The Korubo: One of the tribes living in the Javari valley is the Korubo. They have been hostile towards all outsiders. There as been history of harrasment and killings at the hands of loggers. Reuters reports that in 1996 Sidney Possuelo from Brazil's National Indian Foundation (FUNAI) made the first peaceful contact with Korubo. They have a population believed to be of 200-300 individuals. For more information visit: http://www.nationalgeographic.com/features/96/contact/index.html
Ava Canoeiro: Very few of the Ava Canoeiro survive. FUNAI believes that their may still be 12 individuals hiding in the jungle. Their territory is threatened by a dam that will flood the entire area. For more information visit: http://www.ainfos.ca/A-Infos96/6/0134.html
