EROSIVE PROCESSES AT BACANGA STATE PARK AREA
2009
The conservation measures of the areas reached by irrational way of exploration were adopted in the attempt to preserve the Brazilian ecosystems. There are many Conservation Units, where (theorically) the nature has larger possibilities to resist the human aggressions. In Maranhao there are 10 Conservation Units, two Federal ones and 8 State ones. The state park of Bacanga, which is the object of this work, is a State Conservation Unit located in Maranhao Island founded in 1980 and its objective is to preserve the flora, the fauna and the local springs. Despite the importance of the local ecosystem and the supervision of the responsible institutions, the real predatory actions in the area reflect the lack of ecologic conscience from who attacks the Nature extracting in a criminal way its natural resources. The environment degradation is evident when the erosive processes intensified by the human activities are observed in the local like: removal of the vegetation, the use of the agricultural practice, the urbanism, among others. Those acellerated erosive processes have reached specially the geomorphology of the Park. The silting of the river, the gullies and ravines have standed out in this sceneny of degradation of the soils. This work deals with enviromental problems caused by the human interference that influence directly in the equilibrium of local ecosystem.
