Rainforest Biodiversity
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 a learner can do afterwards
- 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
The lesson
You already know rainforests are full of living things. Here is the surprising part: rainforests cover only about 6 out of every 100 acres of land on Earth, but they are home to more than half of all the plant and animal species scientists have ever found. No other kind of place on Earth packs in so much life into so little space.
Picture a patch of rainforest about the size of two soccer fields, called a hectare. Scientists have counted more different kinds of trees growing in that one hectare than exist in all of northern Europe put together. Take a short walk through a rainforest and you could pass hundreds of tree types you would never see anywhere else.
This is why rainforests matter so much for protecting nature. So many species live only in rainforests that losing this habitat would mean losing plants and animals found nowhere else on Earth.
Rainforests cover just 6% of Earth's land but hold over half of all its species, which is why protecting them is such a high priority.
