Introduction the majority of the people who live of the manguezais does not know the extreme importance that this ecosystem presents. the manguezais are nurseries and hbitats of many species of marine and terrestrial beings. Therefore the preservation and consientizao of this ecosystem are more than important, half of the population is essential for more than that from there takes off its sustenance that is 95% of the littoral communities among others. The fen is composed for only three types of trees (Rhizophora mangle? fen-brave or red, schaueriana Avicena? fen-seriba or seriba? racemosa Laguncularia? fen-white) Red Fen - Rhizophora mangle the name of the tree thus is given therefore, when its rind is scraped, it presents a colored coloration typical of the species. The breath of the plant is made through rizforos, that also assist its sustentation. species multiplies through seeds (propgulos) that they still germinate imprisoned to the plant-mother, increasing the possibilities of the species if to propagate. Fen Preto or Seriba - schaueriana Avicena the fen-black color presents structures of breath called pneumatforos, that are roots that grow in a system to radicular and that later they go up, being above of the ground, thus assisting the breath of the tree. Moreover, the fen-black color has specialized structures called salt glands, that thus are called by the fact excretar the salt that is absorbed by the plant. White fen - racemosa Laguncularia pecolo of its leves is red and presents salt glands what it makes with that through the leaf can be observed small portions of salt, what facilitates the identification of the plant and the type of fen.
