(a.k.a. Serra tumucumaque)
Mountain range in the border region between Surinam, French Guyana, and Brazil. None of the mountains in the Tumuc-Humac range are very high (they only go up to about 850 meters). Nevertheless, the large, rainforest-covered, almost uninhabited region was one of the last blank spots on the world map, remaining Terra incognita until the middle of the 20th century.
In August 2002, the Brazilian President, Fernando Henrique Cardoso, signed a decree making the 38,000 sq.km region a protected national park, the Tumucumaque National Park, and initially restricting access to scientists studying the rich wildlife of the mountains.
The Tumucumaque National Park is the world's largest tropical national park, and home to giant armadillos, anteaters, jaguars, sloths and black spider monkeys, as well as at least 8 species of amphibians, 350 species of birds, and 37 different species of reptiles.
