The landscape more common of Caatinga it is the one that she presents during the drought. In spite of the dry aspect of the plants, everybody is alive; they just lost the leaves to support the lack of water. Even during the drought, the animal life is also rich and diversified. However, it is after the rains that the animal and vegetable diversity of the caatingas becomes evident. The plants flourish and the animals he/she/it reproduces, leaving descending that already possess adaptations to support the long period of following drought.
In full strip sub-equatorial, between the Amazon Forest and the Atlantic Forest, they meet the caatingas of the Brazilian Northeast. They collect about 700 thousand km2, approximately 10% of the national territory. The climate is semi-arid, with annual medium temperatures understood between 27ºC and 29ºC and with medium inferior pluviométricas to the 800 mm. The climatic rigidity of the caatingas is checked mainly by the irregularity in the distribution of these rains in the time and in the space. The superficial escoamento is intense, because the soils are shallow and placed above crystalline lajedos. The rivers are intermittent, that is, they just run during the period of rains, tends its courses interrupted during the station it evaporates. The typical landscape of the caatingas consists of extensive plains interplanálticas and intermontanas, that involve and higher residual massive interpenetram. The vegetation is xerofítica, caducifoliar and open, well adapted to support the lack of water Sandbank he/she is a term employee to designate the plains covered litorâneas for marine deposition, resultant of the I retreat of the levels of oceans there is about 5 thousand years, during the Quaternary. After I retreat it, there were fluvial depositions and lacustre, contends, partly, coming material of the scarps of the Crystalline Complex, characteristics in the South coast and Brazilian Southeast, or of Formação Barriers' arenito. Those plains locate under humid tropical climate, without station it evaporates, with annual medium precipitations about of 1700-2000 mm. The largest amount of nutrients in the plain coastal provém of atmospheric precipitations, being mainly fastened in the vegetable biomassa. The plains litorâneas can come with quite varied extensions, depending of the I retreat of the scarps of the Crystalline lens. The levels marine past oscillated in way to promote the sedimentação in several landings, that are testimonies of this alternate deposition. For the action of the tides, the deposition of marine sediments gave him under the form of sandy cords, having some older terraces. For behind of those deposits and enter the cords it is possible depressions that form várzeas or swamps of fresh water happen.

In the line of beach of the plains litorâneas he/she settles down a vegetation adapted to the saline and sandy conditions under influences of tides, denominated halófila-psamófila, with species herbaceous reptantes, with systems wide radiculares. After this strip, on stableer cords, he/she meets a vegetation arbustiva and arboreal dense, denominated jundu, with a lot of bromélias terrícolas. It is characteristic its form of it coins, due to the abrasive action of particles of sand on the yolks gone back to the beach. It presents a not very developed organic layer, with the soil bromélias carrying out a paper estabilizador of the substratum and of retention of water and of nutrients in the system. In the coast of Rio de Janeiro and of the Espírito Santo moitas is developed composed by species arbustivas and arboreal, inserted by discovered soil, whose denomination is given by the presence of dominant rates, as Sandbank of Clusia, of Myrtaceae and of Ericaceae.
On the sandy cords, depending on its age, he/she settles down a forest that is less exuberant than the Atlantic forest, with similar flora, penetration of elements of the Closed, little characteristic species and great amount of epífitas. There are forests that resemble each other to the one of the tops of hills in the coastal mountains, in general on more recent cords, with a lot of Myrtaceae and bromélias terrícolas.
In the marine terraces it is temporarily common to occurrence of areas flooded, that support várzea forests. Among the cords there is depression that can be permanently humid, sustaining forests paludosas, with little species arboreal adapted and a lot of bromélias on the flooded soil. In the basins of organic soil the forest paludosa is developed so much as the fields taboa monoespecíficos or of lily of the swamp. This group of formations on the plain litorânea establishes a mosaic of variable granulation, enlarging its biological diversity. The fauna of mammals and of birds that it happens at the forests on the sandbank it is similar to the one of the Atlantic forest, indicating interactions associated to the temporary and space alternatives of nutritious resources, of shelter and of nidificação. These pluvial forests associated to the Atlantic domain have few remainders preserved in Units of Conservation, mainly for the urban occupation of the plains litorâneas.
