This article begins with a series of discussions on the identification of sacred sites in the locality of Iauaretê, situated on the shores of the middle Uaupés River, between 2004 and 2011, involving the participation of local indigenous leaders and representatives of the National Historical and Artistic Heritage Institute (IPHAN). The work of identifying these sites began with the institute's visit to the region in 2004 and the partnership established with the Federation of Indigenous Organizations of the Rio Negro (FOIRN) and the Instituto Socioambiental (ISA), a non-government organization that has provided advice and support to indigenous peoples of the region for two decades. Following an evaluation of the effects of the listing of the Iauaretê Falls as intangible heritage by IPHAN in 2005, as well as the preservation actions implemented subsequently, the article explores some aspects of the new collaborative dynamics between anthropologists and indigenous researchers/intellectuals which the experience brings to the fore, as well as the specific way in which this phenomenon is manifested in the context of the upper Rio Negro.
