[1] The National Park is located between the states of Goiás and Mato Grosso do Sul in the Center-West Region of Brazil, between 17º50’—18º15’S and 52º39’—53º10’W.

Emas National Park shows a typical cerrado ecosystem; a treeless savannah with tall termite mounds and an interesting amount of wildlife: the giant anteater, the maned wolf, giant armadillo, pampas deer[3] and the namesake greater rhea, among others.

Emas National Park also holds a small jaguar population, perhaps consisting of about 10-12 animals.

Only about 40% of the reserve, which covers 1,320 square kilometres (510 sq mi) in total, is good jaguar habitat.

[4] Other larger mammals include puma, ocelot, Brazilian tapir, collared peccary, white-lipped peccary, marsh deer, red brocket, gray brocket, black howler monkey and capybara.
