The importance of tropical forests and the surrounding environment has been increasing, as specific threats and problems (e.g. deforestation, timber logging, infrastructure development, and mining) are generating increased atmospheric carbon dioxide concentration, with severe present and future consequences in climate (Schulze in Carreiras et al., 2006). Rio de Janeiro is a Brazilian state that presents the greatest diversity of ecosystems, including major portions of Atlantic Forest (Mata Atlântica in Portuguese), considered a hotspot for its importance and relevance in terms of natural resources and biodiversity. The high biodiversity in this biome is a function of the extreme variations in environmental conditions, and great differences in altitude, ranging from sea level to over 1800 meters. The Atlantic Forest domain has the following delimitations established by the Brazilian Vegetation Map of IBGE (Veloso et al., 1991): ombrophilous dense Atlantic Forest; mixed ombrophilous forests; open ombrophilous forests; semidecidual stational forests; decidual stational forests; the countryside swamps, the northeastern forest enclaves (regionally called "brejos") and the associated ecosystems mangroves and restingas. According to publication of SOS Atlantic Forest Foundation and the Brazilian National Institute for Space Research (2009) between 2005 and 2009, there was a loss of 1,039 hectares of Atlantic Forest in the state of Rio de Janeiro. The Forest is now fragmented in isolated remnants scattered throughout a landscape dominated by agricultural uses. According to Grimm et al. (2008), ecosystem responses to land changes are complex and integrated, occurring on all spatial and temporal scales as a consequence of connectivity of resources, energy, and information among social, physical, and biological systems. As terrestrial landscapes become increasingly fragmented, so do hydrologic connections between landscape elements (Pringle, 2001). The extensive deforestation at the Basin took place over a historic period. The colonization process of the area, specially of dense ombrophilous forest, was initially with sugar cane, coffee and orange plantations, followed by cattle raising and annual crops (CIBG, 2010), which favored the formation of erosive processes as well as silting of water bodies. The only area with significant forest remnants is found in high slopes, inappropriate for agriculture,
