In 1975 Funai made an overflight of the area and located a huge hut with an estimated population of 80 individuals. The Amapari region is the present area of concentration of the Wai pi who live in Brazil. This area is located in the municipalities of Mazag o and Macap , in the state of Amap . The area hosts a dense rainforest area, where small waterways prevail, all of them full of rapids. The region is extremely uneven and broken, and consists of a sequence of hills and some flatlands, located at the foot of the Iratapuru, Ipitinga and Tumucumaque ranges.
Soils are predominantly acidic, argilliferous and sandy with a high erosion risk.
Political schisms and meetings of members of different groups contributes for the constant reunification of the population of the villages, as well as disease outbreaks, deaths and intermittent prospector invasion problems. The agricultural cycle and the depletion of game also influence the migration of the Wai pi throughout their territory. Each hut corresponds to one family nucleus or, in rare cases, to one extensive family, housing between 4 and 7 individuals in the average. The two-sided roofing is made of ubim leaves and black straw. They presently are being replaced by large low-rise buildings, without walls, or by simple, rudimentary, provisional tapiris .
