Only 19.8% Remaining in
Rio de Janeiro
(2012)
Great diversity and
endemismNumber of species:
20000 plants (35% of the
country)
370 amphibians
200 reptiles
270 mammals
350 fish
120 millions of people
70% of Brazilian Gross
domestic Product (GDP)
Original atlantic forest
Remaining Atlantic Forest

Introduction
Study site
Guapi- Macacu Basin
• Population: 110000 habitants
• Drainage area: 1256 Km2
• Climate: Subtropical
• Anual mean temperature range: 18 to 23 oC
• Anual mean precipitation: 1500 – 2500 mm
• Maximum Elevation: 2250 m.a.s.l.
• Air moisture: around 83%

Results and discussion
Conclusions
• MIRS and CSSI was able to identify the hotspots of soil erosin
• Activities of extracting sand (upper part of Sector C and D) need
to be revised and adjusted to avoid the Macacu River siltation
• Riparian forests should be introduced in sugarcane (Sector C)
and pasture (Sector A) areas.
• Burning activities should be eliminated
• The river bank erosions present in the Sectors A, B, and C should
be recovered.
• There are several plant species that are economically valuable,
well adapted to the Atlantic Forest ecosystems and can be used
successfully for the recovery of riparian forest and river bank
erosions
