To mark the 20th anniversary of the creation of the "Yanomami Park'in Brazil, the Yanomami Indians have released rare aerial film footage showcasing an uncontacted Indian community in the region.

This Yanomami region close to the border of Brazil-Venezuela is the largest forested indigenous territory in the world. As a result of this, several uncontacted tribes including the one in the footage have managed to survive in the region.

The scenes were captured during an overflight carried out by Brazil's Indian Affairs Department, FUNAI, and the Yanomami organization Hutukara.

For around 20 years, after the ratification of the Yanomami territory in Brazil, the uncontacted tribes are in great danger due to miners illegally working only about 15 km from their village. These goldminers are putting the Indians' lives at risk by transmitting diseases and polluting their rivers with mercury.

The Yanomami reportedly suffered years of oppression at the hands of gold-miners. Violence and disease saw their population fall by 20 percent in just seven years.

The images taken by Yanomami for their association, Hutukara showed how how uncontacted members of the tribe continue to live in the Amazon, building traditional malocas at the heart of their communities.

Survival International reported that although an operation is under way to remove them, the contacted Yanomami are calling for proper long-term measures to keep illegal invaders out.

Davi Kopenawa, Yanomami shaman and spokesman who has become known as "the Dalai Lama of the rainforest", says in the film: "I would like the non-Indians to respect their own law... so the uncontacted Yanomami can live in peace".

Last year, in November, Survival released a series of pictures proving the existence of this uncontacted Yanomami community. These pictures emphasised how important the territory is in protecting the Yanomami from goldminers who devastated the tribe in the 1980s.

The Yanomami Park in Brazil was created on 25 May 1992, following years of campaigning by Davi Kopenawa Yanomami, Survival International, and the Pro Yanomami Commission.

Survival continues to work alongside the Yanomami of Brazil and Venezuela, in their campaign to protect their forest from invasions.
