The canopy is the second
highest layer of the rainforest. It's like a dense roof of trees over the
ground. It's 80 to 150 feet above the ground and is always
green and leafy. It shields the ground from the sun and light rain,
though heavy rains do find their
way through. Some creatures up there never go to the forest
floor. Many butterflies, such as the tawny rajah, live up
here. Many trees up here have leaves that end in a narrow point,
which helps get water off the leaf. If the water didn't get off the
leaf, algae or liverworts could grow on it. It
is very hard for scientists to study the rainforest canopy, because it's
so hard to reach. So they build walkways up in the trees so that
they can just walk around up there.
