The Rio Preto State Park (Portuguese: Parque Estadual do Rio Preto) is a state park in the state of Minas Gerais, Brazil. It protects a mountainous area of cerrado vegetation that is home to various endemic, rare or endangered species. Trails provide environmental interpretation, and lead to lookouts that give panoramic views, to rivers and waterfalls, and to archaeological sites with rock paintings.
The Rio Preto State Park is in the municipality of São Gonçalo do Rio Preto, Minas Gerais, 70 kilometres (43mi) from Diamantina. It has an area of 12,184 hectares (30,110 acres).[1] It is 355 kilometres (221mi) from Belo Horizonte, the state capital. A section of a 1,400 kilometres (870mi) colonial-era Estrada Real (Royal Road) passed through the park, and traces still remain. This was a route used by gold and diamond prospectors.[2]
The park covers part of the Espinhaço Mountains. It has a rugged relief with quartz rocks that form beautiful cliffs. The park holds several springs, notably that of the Rio Preto, one of the main tributaries of the Araçuaí River, which in turn is a tributary of the Jequitinhonha River. The abundant watercourses form waterfalls, natural pools, rapids, sinkholes, canyons and fluvial beaches with white sands.[1]
History
The Rio Preto was declared a "permanently protected river" in 1991 in response to demand from the local community. The Rio Preto State Park was created by decree 35.611 of 1 June 1994, with an area of 10,755 hectares (26,580 acres). It was opened to visitors in 2002. Decree 44.175 of 20 December 2005 enlarged the area of the park.[1] The park became part of the Espinhaço Mosaic of conservation units, created in 2010.[3]
In April 2013, the Public Ministry and Justice department of Minas Gerais charged that the State Forestry Institute had been failing to comply with environmental legislation. There were serious problems such as lack of a management plan, physical structures and personnel, and land tenure issues with the ecological stations of Mata do Acauã and Mata dos Ausentes and the state parks of Biribiri, Alto Cariri, Rio Preto and Serra Negra.[4]
Environment
The park includes lands that used to be the Boleiras, Alecrim and Curral farms. Former activities included animal husbandry, capture of live animals and collection of wild fruits.[1] Average annual precipitation is 1,500 millimetres (59in), with more than 90% falling between October and March. Average annual temperatures ranges from 18 to 30°C (64 to 86°F), with cooler temperatures in the dry season.[2]
Vegetation is characteristic of the cerrado, including leaning, twisted trees with irregular, distorted branches from 3 to 6 metres (9.8 to 19.7ft) high. Lower trees are found at altitudes above 900 metres (3,000ft) and between rock outcrops. Semi-deciduous trees are found in the stream valleys. The eastern part of the park has flora found in the Atlantic Forest.[2] The park's vegetation in mostly cerrado and alpine tundra. Flora include monjolo, pau pereira, candeia, sucupira, pau d'óleo, peroba, ipê, araticum, carvalho and various species of evergreens.[1]
Endemic birds include the hyacinth visorbearer (Augastes scutatus), Cipo canastero (Asthenes luizae) and serra finch (Embernagra longicauda).[2] The burrowing owl (Athene cunicularia), masked water tyrant (Fluvicola nengeta) and grassland sparrow (Ammodramus humeralis) are also found. Mammals include endangered species such as the maned wolf (Chrysocyon brachyurus), giant anteater (Myrmecophaga tridactyla), giant armadillo (Priodontes maximus) and ocelot (Leopardus pardalis).[1] Other mammals include cougar (Puma concolor) and deer. There are native species of fish, including the jundiá, discovered in Rio Preto and still poorly researched.[2]
