Subsídios para a proteção de áreas úmidas da bacia do rio Xingu (Mato Grosso, Brasil)

Abstract: e André Villas-Bôas 5 RESUMO -O rio Suiá-Miçu é um importante tributário do rio Xingu, e sua bacia hidrográfica (BHSM), situada no planalto do Parecis, Estado de Mato Grosso, abrange 2,36 milhões de hectares. A BHSM contempla Formações Pioneiras, Cerrados e a Floresta Estacional Perenifólia, cuja composição de espécies é consequência da variabilidade de chuvas e do clima estacional. O objetivo deste trabalho foi caracterizar as áreas úmidas da BHSM e sua importância para a preservação ambiental. O mapeamento d… Show more

“…However, wild areas of this region have been continuously used to agricultural activities (Brannstrom et al, 2008). Such environmental changes may have strong impacts on the water quality of this large river (Sanchez et al, 2012). Several studies have evaluated the consequences of these alterations in aquatic systems (e.g., Dias-Silva et al, 2010;Shimano et al, 2010;Silva et al, 2010;Souza et al, 2011;Pereira et al, 2012;Brasil et al, 2013;Carvalho et al, 2013).…”

“…The floodplains encompass the tributary rivers such as Manitsauá-Miçu, Rio Mosquito (or Huaiá-Miçu), Auaiá-Miçu and Suiá-Miçu. Thus, the region is an important source of common resources and goods of public interest, such as the permanent preservation areas (gallery forest), or PPAs (Benjamin, 1997;Sanches et al, 2012).…”

“…This agribusiness trend has led to the drastic transformations in the landscape and socioeconomics of the region, such as the case of Querência municipality (Figure 1), which depended economically on timber extraction and extensive livestock farming. Currently, this municipality is the regional leader among the largest soybean producers in Mato Grosso, and it has the highest rate of deforestation (Sanches et al, 2012). All of these changes affected the quality of the rivers and resulted in more than five million deforested hectares and 300,000 hectares of permanent preservation areas (gallery forest) degraded in the Xingu basin (Sanches & Villas-Bôas, 2008;Sanches et al, 2012).…”

“…The concept of flood pulse (Junk, 2005) considers the lateral exchanges between the river and its floodplain, as well as the change and exchanges between the terrestrial (dry) and aquatic (flood) phases on the same plain. Therefore, the system can incorporate and efficiently take advantage of the organic matter, which explains the richness and diversity of rivers with floodplains (Sanches et al, 2012).…”
