Components of System Main Influences

• Lower Order streams
• Vegetation land use change (riparian veg)
• soil type
• Human impacts mining, urban agricultural
• Mid-sections of Major tributaries
• Dams upstream downstream effects
• Fisheries
• Urban agricultural pollution
• Modification of floodplain habitat
• Main stem Amazon river major tributaries
• -fisheries
• Urban pollution
• Modification of floodplain habitat (ag ranching)

17
Main Components Aquatic Model Lower Order Basins

• Climate vegetation rainfall
• Rainfall vegetation runoff
• Runoff vegetation cover soils stream flow
  water quality
• Riparian veg stream flow water quality
  aquatic biodiversity

Conservation Value Aquatic System

• Intrinsic value aquatic biodiversity
• Indicator of environmental status of basin
• Functional unit of landscape level hydrological
  processes
• Release of carbon generated by terrestrial
  systems
• Critical resource fish fresh water

Land Use on the Floodplain
As restingas são utilizadas para a agricultura e
a pequena criação
Os campos, as pastagens nativas, são utilizadas
pela pecuária.
Os lagos, são utilizados para a pesca.
