| The importance of the water in the current geo-political context turns it into a research theme that focuses on conserving its quality and improving its use conditions in certain systems. The hidrologic cycle consists of water exchanges among rivers, lakes, and oceans, as well as atmosphere and soil. The species of the gender eucalyptus possess a very fast growth rate in relation to native species, what causes a large demand for water, even though their water use efficiency is better. As well as any vegetable species, the eucalyptus uses water to satisfy their physiologic demands, promoting its growth. As a result eucalyptus promotes reduction in the flow of water in watercourses. Areas covered with forest plantations, besides improving the landscape as a... |

| A água é fundamental à manutenção da vida, sendo um recurso de múltipla utilização. A qualidade da água depende das condições naturais e da ocupação do solo na bacia hidrográfica.. Este trabalho teve como objetivo avaliar a qualidade físico-química da água da bacia hidrográfica do córrego Zerede, MG. As análises foram realizadas no Laboratório do Meio-Ambiente- LCP, UFV/Viçosa. Os parâmetros avaliados foram pH, condutividade elétrica (Ce), OD (oxigênio dissolvido), DQO (demanda química de oxigênio). De acordo, com a caracterização físico-química efetuada nesse trabalho, pode-se concluir que a qualidade da água está nos padrões da Resolução CONAMA 357 enquadrando nas classes especial e classe I. |

| The objective was to evaluate a reforestation carried out by the goldwashers. The studied area is situated along the Gualaxo do Norte river margins in Mariana - MG. The seedlings were received by donation of regional nurseries and were planted on December of 2006 in hole of 25x25 cm and plant spacing 3x2 meters. The evaluations were carried through on March of 2007. The height was measured with metric ribbon and the diameter, 5 cm above the ground, was done by using digital pachymeter. They planted 538 seedlings of 20 different species, pertaining to twelve botanical families. The most abundant species were Enterolobium contortisiliquum (96), Mimosa schomburgkii (76) and Chorisia speciosa (45). It was not possible to identify 19 individuals due to... |
