Forests do a lot of environmentally friendly things.
They absorb carbon dioxide and store carbon, and help protect soil
from erosion. They help clean our drinking water by filtering water
before it enters creeks, streams and underground water supplies.
They are the home (habitat) for many plants, animals and other living
things. They also provide us with a natural and renewable material -
wood - that we use in our everyday lives.
Wood is renewable, recyclable and biodegradable. It is a product of
solar energy (energy from the sun). It is also one of the most
energy efficient materials we use.
National Parks (preserved
forests)
Because of increasing interest in and
concern about the environment, in recent years society has demanded
that large areas of forest be set aside so that trees, plants and
animals can be allowed to live and grow without human disturbance.
These areas are national parks and conservation reserves (preserved
forests).
We try to find a balance between preserved
forests and working native forests (State forests). Our working
forests are looked after by specially trained State foresters. Our
preserved forests are looked after by national park rangers.
National Parks include most of our oldest
forests. Areas which contain lots of older trees are known as 'old
growth' forests. Old growth forest consists of old trees growing in
an area where there has been no logging, road building or land
clearing. The oldest trees in an old growth forest can be more than
two hundred years old. Many of the trees will have numerous hollows
in them, which animals use to build their nests. The canopy (the top
leaves and branches of the trees) will take up about 30 per cent of
the forest area.
Old growth forest trees can't live forever.
Eventually they will die, and be replaced by new young trees.
