A new uncontacted Amazon tribe in Brazil was discovered and recently confirmed by National Indian Foundation (FUNAI) of Brazil, a government body overseeing indigenous peoples.

“This is a great discovery that required very careful and intense work,” the Chief of FUNAI Carlos Travassos told Al Jazeera.

The tribe in the area of Javari Valley in the western Amazon is believed to have around 200 members, according to the report. Their existence was initially discovered through satellite images earlier this year and later confirmed by a team of examiners in an aerial flight over the area.

According of Fabricio Amorim of FUNAI who led the overflight expedition, the tribal people were growing corn, bananas, peanuts, and other crops.

FUNAI do not endorse contacting the tribe, but only to monitor their land and activities to ensure their lives are undisturbed. They have not given out the exact location of the site.

Amorim warned, “Among the main threats to the well-being of these groups are illegal fishing, hunting, logging, mining, cattle ranching… and drug trafficking.”

The Brazilian government also mentioned the danger of disrupting their natural habitat or spreading germs that the tribal people were not immune from.

According to Survival International, the Javari Valley has the highest concentration of uncontacted tribes in the world. National Geographic reports that around 8 to 14 uncontacted indigenous communities, with approximately 2,000 people, are there.
