The Kayapo tribe lives alongside the Xingu River in the eastern part of the Amazon Rainforest, near the Amazon basin. They live in several scattered villages ranging in population from, one hundred to one thousand people in Brazil. Their land consists of tropical rainforest savannah (grassland). It is arguably the largest tropical protected area in the world covering 11,346,326 million hectares. They have small hills scattered around their land and the area is criss-crossed by river valleys. The larger rivers feed into numerous pools and creeks, most of which don’t have official names.
