The Antimary State Forest (Portuguese: Floresta Estadual do Antimary) is a state forest in the state of Acre, Brazil. It was the first state forest in Acre, established with the goal of understanding and implementing sustainable forest exploitation, including extraction of nuts and rubber as well as selective extraction of timber. It has been extensively studied and discussed internationally as a model of sustainable forest management.
The Antimary State Forest is divided between the municipalities of Sena Madureira (26.94%) and Bujari (73.06%) in the eastern part of the state of Acre. It is north of the BR-364 highway, and is bounded by the border with the state of Amazonas to the northeast. It has an area of 47,064 hectares (116,300 acres).
Average annual temperatures are 25 °C (77 °F). The land is relatively flat, with maximum elevation of about 300 metres (980 ft) above sea level. Soils are mainly dystrophic yellow latosols with high clay content. Annual rainfall is about 2,000 millimetres (79 in). The dry season from June to September is used for slash-and-burn land clearance for agriculture and for forest management and logging. Satellite images show that the forest is:
The most common flora are from the Caesalpinaceae, Mimosaceae, Moraceae, Fabaceae and Euphorbiaceae families. The State of Acre Technology Foundation (FUNTAC) has identified 625 species of flora including 361 of trees and 18 of palm trees. There are 114.5 trees per hectare on average, with an average basal area of 15.23 square metres (163.9 sq ft) per hectare and an estimated volume with bark of 128.98 cubic metres (4,555 cu ft) per hectare.
The Antimary River is first mentioned in a 1907 letter by José Plácido de Castro on navigation of the Acre River. He described the main geographical points of the Antimary, a tributary of the Acre. He noted that there were several shacks on the river banks, indicating the presence of rubber tappers. The area of the forest was declared a reserve on 26 June 1911, but nothing more was done at the time. Before Antimary State Forest was created there were 80–100 families living in the forest. Most of the population were rubber tappers, and most come from Acre. About 28% come from other states, particularly Ceará.
