The Pernambuco coastal forests is an ecoregion of the Tropical moist broadleaf forests Biome, and the South American Atlantic Forest biome. It is located in northeastern Brazil.
The Pernambuco coastal forests occupy an 80 km-wide strip along the Atlantic coast of northeastern Brazil in the states of Pernambuco and Alagoas. The forests extend from near sea level to 600–800 metres (2,000–2,600 ft) in elevation, on the windward slopes of the Borborema Plateau.
The Goiana River of Pernambuco marks the forests' northern extent, and the Mundaú River of Alagoas the southern extent.
The ecoregion is bounded on the east by the Atlantic Ocean and the coastal Atlantic Coast restingas forests and Rio Piranhas mangroves. To the east, the forests transition to the drier Pernambuco interior forests and Caatinga.
The ecoregion has a tropical climate with annual rainfall ranging from 1,750 to 2,000 mm. There is a dry period from October through January.
The four-tiered evergreen Atlantic moist forests are the predominant vegetation type.
The ecoregion is an endemic bird area that harbors 13 threatened species of birds. It also harbors the last populations of the red-handed howler monkey (Alouatta belzebul) and blond capuchin (Sapajus flavius) in the Atlantic Forests.
Coastal forests in Pernambuco have a long history of deforestation. The first cycle of destruction was due to "Pau-brasil" (Caesalpinia echinata) extraction. After the extraction of Pau-brasil, through the mid-20th century, the sugarcane industry was mainly responsible for the forest clearing.
Forests remnants are small, most with less 10 km² and surrounded by sugarcane fields. There is only 87 km² of isolated conservation units. It isn't an enough amount to maintain biodiversity and key ecological processes. [2] The largest reserve is Murici Ecological Station (6132 ha). [3]
A biome is a biogeographical unit consisting of a biological community that has formed in response to the physical environment in which they are found and a shared regional climate. Biomes may span more than one continent. Biome is a broader term than habitat and can comprise a variety of habitats.
An ecoregion is an ecologically and geographically defined area that is smaller than a bioregion, which in turn is smaller than a biogeographic realm. Ecoregions cover relatively large areas of land or water, and contain characteristic, geographically distinct assemblages of natural communities and species. The biodiversity of flora, fauna and ecosystems that characterise an ecoregion tends to be distinct from that of other ecoregions. In theory, biodiversity or conservation ecoregions are relatively large areas of land or water where the probability of encountering different species and communities at any given point remains relatively constant, within an acceptable range of variation . Ecoregions are also known as "ecozones", although that term may also refer to biogeographic realms.
The Global 200 is the list of ecoregions identified by the World Wide Fund for Nature (WWF), the global conservation organization, as priorities for conservation. According to WWF, an ecoregion is defined as a "relatively large unit of land or water containing a characteristic set of natural communities that share a large majority of their species dynamics, and environmental conditions". For example, based on their levels of endemism, Madagascar gets multiple listings, ancient Lake Baikal gets one, and the North American Great Lakes get none.
Tropical and subtropical moist broadleaf forests (TSMF), also known as tropical moist forest, is a subtropical and tropical forest habitat type defined by the World Wide Fund for Nature.
The Atlantic Forest is a South American forest that extends along the Atlantic coast of Brazil from Rio Grande do Norte state in the northeast to Rio Grande do Sul state in the south and inland as far as Paraguay and the Misiones Province of Argentina, where the region is known as Selva Misionera.
The Serra do Mar coastal forests is an ecoregion of the tropical moist forests biome. It is part of the Atlantic Forest of eastern South America. This ecoregion has an outstanding biodiversity consisting of flora, mammals, birds, and herpetofauna.
The Araucaria moist forests, officially classified as mixed ombrophilous forest in Brazil, are a montane subtropical moist forest ecoregion. The forest ecosystem is located in southern Brazil and northeastern Argentina. The ecoregion is a southern portion of the Atlantic Forest. The ecoregion also includes select areas of open field called "campos de cima da serra" or "coxilhas".
The Alto Paraná Atlantic forests, also known as the Paraná-Paraíba interior forests, is an ecoregion of the tropical moist forests biome, and the South American Atlantic Forest biome. It is located in southern Brazil, northeastern Argentina, and eastern Paraguay.
Restingas are a distinct type of coastal tropical and subtropical moist broadleaf forest in eastern Brazil. They form on sandy, acidic, and nutrient-poor soils, and are characterized by medium-sized trees and shrubs adapted to the drier and nutrient-poor conditions. One of the most notable restingas is the Restinga da Marambaia, which is owned and kept by the Brazilian Army.
The Northeastern Brazil restingas are an ecoregion of northeastern Brazil. Restingas are coastal forests which form along coastal sand dunes in Brazil. The soils are typically sandy, acidic, and nutrient-poor, and are characterized by medium-sized trees and shrubs adapted to local conditions. Restingas have aspects of mangroves, caatingas, wetlands, and moist forests, often forming along wind-driven sand dunes. The Northeast Brazil restingas are the most northerly of the forest type in Brazil.
The Caatinga enclaves moist forests is an ecoregion of the Tropical moist forests Biome, and the South American Atlantic Forest biome. It is located in northeastern Brazil.
The Atlantic semi-deciduous forests, also known as the Atlantic interior forests, are a belt of tropical moist broadleaf forests that are part of the Atlantic Forests complex of eastern Brazil. The semi-deciduous forests form a transitional zone between the humid Atlantic moist forests which lie near the Atlantic coast, and the drier Caatinga shrublands, Atlantic dry forests, and Cerrado savannas of the interior.
The Bahia coastal forests are a tropical moist broadleaf forest ecoregion of eastern Brazil, part of the larger Atlantic Forest region.
The "Pernambuco" interior forests is an ecoregion of the Tropical and subtropical moist broadleaf forests Biome, and the South American Atlantic Forest biome. It lies in eastern Brazil between the coastal Pernambuco coastal forests and the dry Caatinga shrublands of Brazil's interior.
The Bahia mangroves is a tropical ecoregion of the mangroves biome, and the South American Atlantic Forest biome, located in Northeastern Brazil. Its conservation status is considered to be critical/endangered due to global climate change and other factors.
The Amazon biome contains the Amazon rainforest, an area of tropical rainforest, and other ecoregions that cover most of the Amazon basin and some adjacent areas to the north and east. The biome contains blackwater and whitewater flooded forest, lowland and montane terra firma forest, bamboo and palm forest, savanna, sandy heath and alpine tundra. Some areas of the biome are threatened by deforestation for timber and to make way for pasture or soybean plantations.
The Murici Ecological Station is an ecological station in the state of Alagoas, Brazil. It preserves a rugged area of Atlantic Forest that is important as a home for several species of rare or endangered birds.
