After nearly twenty years of discussion, the Peruvian government has moved to establish a new Indigenous reserve for “uncontacted peoples” deep in the Amazon rainforest. Yavarí Tapiche Indigenous Reserve, which covers 1.1 million hectares (2.7 million acres) in the department of Loreto on the Peru-Brazil border, is home to Matsés, Remo, and Marubo peoples, as well as other groups that have yet to be identified.
Yavarí Tapiche will be established under Peru’s law governing territories for peoples in isolation and initial contact (PIACI). These peoples, sometimes popularly known as “uncontacted tribes”, have little or no contact with the outside world and live in some of the world’s most biologically diverse landscapes, including remote parts of the Amazon Basin.
