  1. The Atlantic Forest of the Cacau Coast in Brazil Diverse plants, climate and soils: Opportunities for graduatestudent research

  2. Original Atlantic Forest Extent

  4. Elevation Relief Degree Slope 0,1 =0-5 2 =5-15 3 =15-25 4,5 =25-40 6,7 =40-55

  6. Climate is tropical and over a short distance (<150 km) ranges from wet to dry Tropical Rain Forest Dry Climate Tropical High Altitude Climate

  9. Species richness Atlantic Forest Plant Biodiversity is high and variable…one of the world’s 25 biodiversity hotspots 63-70 55-62 47-54 39-46 30-38 Jardim & Landau, 2003

  10. Plant species richness potential Over 400 tree species per hectare have been recorded

  11. While the Atlantic Forest’s uniqueness is biodiversity, its problems are deforestation and fragmentation

  12. 100 million hectares reduced by 92% Forest exist now as fragments

  13. Semi-deciduous Rain forest cacau pasture Deciduous Dense rainforest regeneration

  14. Ilheus-Itabuna Area

  15. Atlantic Forest Exists as fragments Southern Bahia Based on: Cordeiro 2003

  16. Atlantic Forest • Biodiversity depends on climate, soil and fragment size Cordeiro 2003

  17. The potential for environmental problems is shown by the land use Foto: E.C. Landau, Fev/2000 Area (km2) Landau, 2003 88,350 sq km Foto: E.C. Landau, Jan/2000

  18. Is there interest in the region for collaboration with UF?

  19. Paraphrased from the Director of Research for CEPLAC (a UF graduate) and the Dean of Research of UESC “Why do students from Florida go to the Amazon when the most threatened ecosystems in Brazil and S. America are here?” • Soil biodiversity • Soil chemical diversity • Agroforestry • Soil environmental services

  20. Soil Environmental Services: • Soil carbon accumulation/sequestration • Water quality and quantity • Soil nutrient bioavailability • Control of soil erosion through soil structure development and soil stabilization

  21. Soil Environmental Services: Research on Land Use Change and Environmental Quality Environmental Services: • Are degraded due to deforestation and poor management • Will be used by developed countries to offset activities (i.e. trading of carbon credits) • The lack of infrastructure to enforce environmental regulation places a heavy reliance on services for reclaiming or protecting environmental quality. and……

  22. Services may provide an income to landowners: • Carbon Market • Brazilian Environmental Commodity Exchange
