Wet forests in the Caatinga enclaves
(yellow lines indicate the limits)
The wet forests in the Caatinga exclaves are an ecoregion of the tropical rainforest biome and the South American Mata Atlântica . You are in northeastern Brazil .
The ecoregion forms a series of incoherent, island-like enclaves in the much larger and arid ecoregions of Dornstrauchsavanne and Dornbuschwald Caatinga and subtropical Cerrado savannas .
location
The wet forests in the Caatinga enclaves cover an area of 4800 km² in the state of Ceará , in northeastern Brazil.
The enclaves, also called Brejo de altitude , are located on four larger plateaus , the Chapada do Araripe , Serra de Ibiapaba , Serra de Baturité and Serra da Borborema . The enclaves are located on windward slopes and plateaus at an altitude between 600 and 800 m.
flora
The main vegetation type is seasonal deciduous forests with four vegetation strata and tall trees that are taller than 30 m. The forest is largely similar to the Mata Atlântica further east, but also includes species of the caatinga, cerrado, and the Amazon rainforest .
The high-rise and umbrella layers consist mainly of tree species from the families Fabaceae ( Peltophorum dubium ), Meliaceae ( Cedrela fissilis ) and Apocynaceae ( Aspidosperma parvifolium ).
fauna
The fauna associated with this habitat has a strong association with both the Amazon rainforest and the Mata Atlântica and, to a lesser extent, the Caatinga.
On associated with this habitat animals include birds such as the Gray-breasted parakeet ( Pyrrhura griseipectus ), the ocher piculet ( Picumnus limae ), the Ceará Gnateater ( Conopophaga lineata Ceara ) and the araripe manakin ( Antilophia bokermanni ), Anura as Adelophryne baturitensis and A. maranguapensis , and lizards like Mabuya arajara and Leposoma baturitensis .
In contrast to other groups, only one single mammal species is known to exist in these wet forest slaves , the endemic Rhipidomys cariri , which is one of the climbing mice , described in the 2000s .
conservation
Most of the birds endemic to these wetlands are considered threatened by BirdLife International and the IUCN primarily because of habitat loss . In general, the situation in other animals is poorly known, but arguably similar to that of birds.
