D4.2.3
Level

Concept essentials

  • Deforestation removes both habitat structure and the living biomass that stores many rainforest nutrients.
  • Fragmentation isolates populations and weakens ecological interactions across the forest landscape.
  • Reduced transpiration, erosion, and carbon release connect forest loss to broader environmental change.
