5.3 Impacts on ecosystems
Sustainable ecosystems
There are a wide variety of species or different types of organisms found in a sustainable ecosystem
Natural ecosystems are sustainable ecosystems
Ecosystems that are diverse and are able to provide the needs of the organism
Human activities can turn a sustainable ecosystem to a unsustainable ecosystem
Fire monitoring technology
These times are known as fire season
The new fire monitoring system created by the Australian government, this system uses satellites that have moderate resolution imaging spectrodiometer
Different parts of Australia have different times of the year when fires are most likely to occur
Traditional use of fire
Fire can cause 400 species to germinate after the fire
Germination is when the plant grows from a seed
Fire causes rapid change in the ecosystem
Fuel Reduction burning
Any of these fires that go through native areas incinerate animals and plants
Regular burning is one way of reducing the amount of fuel available for a fire
When there is a long time between fires, the amount of fuel available causes an intense fire
Firefighters can control low-intensity fires more easily
FRB turns an intense fire into a low-intensity fire
After low-intensity fires the animals such as kangaroos and wallabies move back into the area
The ecosystems in the burnt areas still have all the same types of plants and animals as before
Conservationists are concerned that frequent burning reduces the number of different types of living things that are able to survive in an area
Introduced Species
most of the animals and plants we use as food such as wheat and cattle
pet animals such as cats and dogs • animals used for transport and recreation such as the
horse and the camel
Many species of plants and animals have been introduced into Australia. These include
many ornamental plants used in parks and gardens such as the jacaranda and roses
The wool, cotton and leather used to make clothes and furnishings come from introduced species
Animal Control
Introduced animals, such as rabbits, foxes and cats, cause widespread damage to ecosystems
Animal control is often needed to restore native environments and assist farmers
Dingo Fence
The aim of the fence was to keep them out so they wouldn't kill there livestock
Dingoes were a problem for farmers in the late 1800s. Between 1880 and 1885 a fence was constructed to protect the sheep and cattle of southern Queensland from attack by dingoes and other wild dogs
