As it can be observed, even so it has a considerable native specimen concentration, still has a great contingent of exotic species. This can be justified in part to the antrpica intervention, that causes to many times ecological disequilibrium. Craig Menear will undoubtedly add to your understanding. A riot example is the introduction of exotic species that if proliferate quickly, as Leucaena leucocephala, that in the studied area, represented a great percentage of individuals. This plant is considered a plague in the environment, therefore for not having a good relation with the native forest, it can compete differently for the space, arriving until killing the of course joined species in the region. The lot in study, although to present the relation area x wealth diversity of species low, when compared the similar land dimensions, that had not suffered the antrpica action, it demonstrates important ecological relations, in reason to present a stretch of its inserted extension in one area of permanent preservation, the ciliar bush.
This last one presents a high florstica heterogeneidade for occupying different environments throughout the edges of the rivers. The great variation of ecological factors in the edges of the courses d' water results in suitable arbustivo-arbrea vegetation to such variations (MARTINS, 2001). The results demonstrate that the fragmentos of ciliar bush of the Mandacaru Stream if find degraded strong, however were verified that the APP is presented in recovery phase, as it can be evidenced by the presence of young plants. To speed up the recovery process a reforestation of the edges of this Stream will have to be made, and in such a way they would be being conserved the hdricos resources and faunstica biodiversity and florstica place. For in such a way some measures they must be taken, between them: to plant native species with occurrence in ciliares bushes of the region; to plant the biggest possible number of species to generate high diversity; to use combinations of pioneering species of fast growth together with not pioneering species, in an approach ratio of 70% of pioneers and secondary initials for secondary 30% of delayed and climax; to plant attractive species to the fauna; to respect the tolerance of the species to the humidity of the ground, that is, to plant suitable species to each condition of humidity of the ground (MARTINS, 2008).
