Sooretama Biological Reserve, Nature reserve in Linhares, Brazil.

Sooretama Biological Reserve is a nature reserve in Espírito Santo state that protects a large expanse of Atlantic Forest with towering trees and dense vegetation throughout. The landscape features swamps, natural water channels, and thick forest cover that extends across rolling terrain.

The reserve was created on 20 September 1982 by merging two areas: the 12,250-hectare Parque de Refúgio e Criação de Animais Silvestres Sooretama and the 10,000-hectare Parque Estadual Barra Seca. Its origins go back to 1941, when a protected area was delimited by the Barra Seca river, Cupido stream and Lagoa do Macuco as deforestation advanced in Espírito Santo. In 2002 it joined the Central Atlantic Forest Ecological Corridor.

The reserve's name comes from the Tupi-Guarani language and refers to the land of the Soó people. It forms part of a continuous protected area of about 50,000 hectares together with the Linhares Natural Reserve and two private natural heritage reserves, the largest area of Tabuleiro forest in Espírito Santo.

The reserve lies near the BR-101 in northern Espírito Santo, with entry through the municipalities of Sooretama and Linhares. As a strict nature reserve (IUCN category Ia), it is not open to casual visiting; access depends on authorisation from ICMBio, which administers it. The forest is humid and the trails pass through dense undergrowth, so bring long clothing and sturdy footwear.

The reserve protects the ant Dinoponera lucida, one of the world's largest ants, along with the Hercules beetle, Dynastes hercules. Its 27,858 hectares also shelter the red-billed curassow and the banded cotinga, birds tied to lowland Atlantic Forest.
