The submitted project is a proposed assessment understandable and, above all, workable, through a first characterization exercise of a biological corridor, for from then on be internalised the social and environmental problem. For the specific case of the research is determined that the Cano Suria is going through this situation, in addition, the demand for land has disrupted the actual values, and lack of environmental controls threatens the sustainability of the gallery forests own of biological corridors, breaking the chain of balance of nature, giving way to different economic activities in search of a monetary welfare, but at the expense of a public good.
