Good to know
Six things about the rainforest
Layers
A forest in layers
A rainforest has floors like a building: the dim forest floor, the understorey, the leafy canopy and a few giant trees above it all.
Rain
Rain most days
It rains on most days of the year, often in a heavy burst in the afternoon.
Light
Dark at the bottom
So little sunlight reaches the ground that the forest floor is surprisingly open and easy to walk through.
Size
The Congo Basin
Africa's great rainforest covers an area bigger than western Europe, and stores a vast amount of carbon.
Home
A crowded home
Rainforests cover a small part of the Earth but hold more than half of all its kinds of plants and animals.
Help

A forest worth keeping
The Congo Basin is the second largest rainforest on Earth. Most of the animals on this page live nowhere else, and all of them depend on it staying standing.
