Southeast Areas

Throughout the history of the country, the native forest covering, represented for different biomas, was being broken up, yielding space for the agricultural cultures, the pastures and the cities. The notion of inexhaustible natural resources, given to the continental dimensions of the country, stimulated and still it stimulates the expansion of the agricultural border without the concern with the increase or, at least, a maintenance of the productivity of the cultivated areas already. Thus, the process of forest spalling is intense in the regions economically more developed, that is, the Southeast and the South, and quickly advances for the Center-West and the North, being the represented native arbrea vegetation, mainly, for secondary forests, in varied been of degradation, saved some reserves of well conserved forests. This process of elimination of the forests it resulted in a set of ambient problems, as the extinguishing of some species of the fauna and the flora, the local climatic changes, the erosion of ground and assoreamento of courses d water. In this panorama, the ciliares bushes had not escaped of the destruction; for the opposite, they had been white of all the type of degradation. It is enough to consider that many cities form formed to the edges of rivers, being eliminated itself all type of ciliar vegetation; many finish paying a high price for this, through constant floodings. Beyond the urbanization process, the ciliares bushes suffer antrpica pressure for a series from factors: they are the areas directly more affected in the construction of hydroelectric plants; in the regions with caused an accident topography, they are the preferential areas for the opening of roads, for the implantation of agricultural cultures and pastures; for the pecuaristas, they represent obstacles of access of the cattle to course d water.
