This study evaluates the potential environmental assaults committed by mining
companies operating in the state of Amapa, in the municipalities of Serra do
Navio and Pedra Branca do Amapari, in 2007. Based on a technical report
requested by the Office of the State of Amapá (MPEA), through a contract
signed with Prof.. Milton Matta (FAGEO-IG-UFPA). The main objective was to
assess the degree of aggression on forest ecosystems in areas where existing
companies that carry out mining activities are working. The influences on the
vegetation in aquatic systems have shown marked only in the areas of river
William basin. Especially in the stretch that extends between the river and
Amapari gold mine ( MPBA). In other water courses of the studied area,
including the streams Silvestre, Mario Cruz and Taboca, the aggression in
relation to vegetation are restricted to areas of deforestation for mining activities
and the areas of road construction for the various access roads from mining.
Some interferences of the MPBA mining company on local vegetation are clear
in the studied area, such as discoloration of the water in streams due to the
large amount of sediment carried to these ecosystems, which ultimately affects
the vegetation can be found there. The main recommendations include the
recovery of degraded areas, with creation of the emerging complexity of
ecosystems that can restore the cyclical processes. It is suggested to start from
Monodominant Ecosystems (eg, grass field), progressing to heterogeneous
(mixed) in order achieve maximum structural and functional complexity, both in
areas of extraction (removal) and in disturbed areas (industrial infrastructure,
support and transportation system. |
