The Rupununi Savannah is a savanna plain in Guyana, in the Upper Takutu-Upper Essequibo region. It is an ecoregion of the Tropical and subtropical grasslands, savannas, and shrublands Biome.
The Rupununi Savannah is located between the Rupununi River and the border with Brazil and Venezuela. The Rupununi forms the southwestern wilderness territory of Guyana, a Caribbean country situated on the Northeastern littoral of South America. The savannah is dissected by the Kanuku Mountains. The Rupununi Savannah encompasses 5000 square miles of virtually untouched grasslands, swamplands, rain-forested mountains. The region usually floods in the wet season (May to August). Early European explorers believed that the Rupununi floodplains were the legendary Lake Parime. The area is inhabited by some 15,000 Amerindians.
The savannah is divided north from south, by the Kanuku Mountains, Guyana’s most biologically diverse region. According to Conservation International, the "area supports a large percentage of Guyana’s biodiversity", including 250 species of bird life, 18 of which are native "only to the lowland forests of the Guianas." The savannah is teeming with wildlife, including a large variety of bird species. The savannah is also home to the jaguar as well as the Harpy Eagle, the world’s most powerful bird of prey, an extremely rare and endangered species which once ranged the forests of South America and is found in the Rupununi/Kanuku mountain range.
