1 What is a Rainforest
Canopy: The canopy is just like a roof to the rainforest. It consists
of many different tree-tops and vines as well as small plants. Some trees
are the Umbrella Tree, Euodea and the Silky Oak tree as well as the Red
Cedar. Some plants are Mistletoe and the Black Bean flower.
Understorey: The understorey includes the smaller shrubs, bushes, ferns,
small trees and the trunks of other trees. Some of these include orchids,
Native Monstera and a lot of different ferns such as the staghorn fern,
elkhorn fern, birds nest fern, and the tree fern or Cooper’s treefern.
Forest Floor: The forest floor is home to mosses, fungi, rotten tree
branches as well as various insects, marsupials and rodents.
Giant Rainforest Trees: The Red Cedar is one of the most important
trees in the history of Australia. It was also know as ‘red gold’ to the
early settlers!
2 Bio-diversity (flora & fauna)*
Tropical rainforests are home to nearly 90% of all the species on earth.
In fact, there are so many animals and plants that scientists believe that
there are still many to be discovered and even to be named! There’s so
many different types of animals that it contains up to 50% (half) of the
species that live on earth! Scientists also believe that there are nearly
50 million different species of insects in a rainforest. Sometimes there
are up to fifty different types of ants in one tree. You would only need
a few hours of poking around in a rainforest to find a new species. This
is believed to be caused by the ‘Giant Freeze’ which didn’t reach the rainforests.
Therefore, plants and animals could keep on living and developing to one
of the oldest, most complete, ecosystems on earth.
3 Decay and Renewal
In a rainforst nothing is wasted. Plants are always shedding leaves
and bark which mixes with the manure of other animals and the bodies of
dead ones to form a layer called ‘humus’ on the forest floor. Micro-organisms,
bugs and fungi break the humus down and change it into rich nutrients for
the soil.
4 Food Chains.
As you can see, humans end up on the end of these food chains. This
is because of modern technology and guns (or weapons).
5 Indigenous* People
A lot of people still live in tropical rainforests. Many have moved
to live just as we do, but, may still live just like their ancestors.
6 Where are the Rainforests?
Rainforests are found in equatorial* regions. They are there because
they need alot of rainfall and a high average temperature. Therefore they
are in parts of Africa, Indonesia, India, Australia, Papua New Guinea and
South America.
7 Climate
Animals rarely have to worry about being cold or starving in a rainforest
with a constant 750 to 800 F (240 to 270
C). Water is never a problem because rain falls nearly every day.
8 Importance of Rainforests
A rainforest is one of the most important parts of life. They are even
often called ‘The Womb of Life’. They are home to animals and have many
helpful plants. Furniture is made from the rainforest’s trees. Medicines
such as a treatment for cancer, is made of plants from the rainforest.
9 How to Help
• Don’t buy products from the rainforest that are not used responsibly
(furniture etc.)
• Try walking places instead of driving.
• Don’t support ‘rainforest-beef’*
• Try to buy rainforest-safe products eg. tree free paper which is
made from the kenaf plant, not trees.
• Try not to place impact on the rainforest when walking.
• Use less paper. Try and use cloth towels not paper ones.
10 Destruction
Everyday the rainforests get more and more destroyed. Trees get cut
down, animals die and today only a little rainforest remains. Try to use
the ‘How to Help’ tips above.
11 Glossary
Bio-diversity: the range of flora, fauna and micro-organisms
in an eco-system.
Indigenous: native, belonging naturally
Equatorial: area near the equator
