Rainforest Biodiversity

Science · Rainforests · conceptual

Understand that rainforests are biodiversity hotspots — covering just 6% of Earth's land surface but containing over 50% of all known plant and animal species — and that this extraordinary richness makes them irreplaceable for global biodiversity and a priority for conservation

What mastery looks like

  • State that rainforests cover about 6% of Earth's land but hold over 50% of all species
  • Explain why this concentration of species makes rainforests a conservation priority
  • Give specific examples of rainforest biodiversity, such as one hectare containing more tree species than all of northern Europe

Check your understanding

Can Rainforest Biodiversity explain the mind-boggling fact that rainforests cover only a tiny fraction of Earth but are home to more than half of all species — and why that makes protecting them so important?
