Learning goals
Learners will
- Identify the main types of natural vegetation in Australia.
- Explain how vegetation supports animals, people and the environment.
Success looks like
- I can name four types of natural vegetation found in Australia.
- I can give three reasons vegetation is important.
- I can describe the vegetation in my local area.
The big idea
Vegetation means all the plants growing in an area. Native vegetation is made up of plants that grow naturally in Australia.
Australia has many types of natural vegetation:
- Rainforests in wet areas of the east coast and the tropical north, with tall trees and many layers of plants.
- Eucalypt forests and woodlands, the most widespread forests in Australia. There are hundreds of species of eucalypt.
- Grasslands and shrublands in drier areas, including spinifex grasslands and mulga and mallee shrublands across inland Australia.
- Mangroves along tropical and warm coastlines, which protect coasts from storms and are nurseries for fish.
Vegetation is important because it provides habitat and food for animals, produces oxygen, gives shade, cools the land, holds soil together to prevent erosion, and filters water. People use plants for food, medicine, building materials and enjoyment.
First Nations Australians have deep knowledge of native plants and have cared for vegetation for tens of thousands of years, including through cultural burning, which can reduce fuel and encourage new growth. Today some land managers work with First Nations rangers to apply this knowledge.
Worked examples
Vegetation and animals
Explain how eucalypt woodland supports koalas.
- Koalas eat the leaves of certain eucalypt trees.
- They live and shelter in the trees.
- If the trees are cleared, koalas lose both food and habitat.
Answer: Eucalypt woodland provides koalas with food and habitat.
Vegetation and soil
Why might a hillside with no plants suffer more erosion?
- Plant roots hold soil in place.
- Leaves slow down falling rain.
- Without plants, rain and wind can wash or blow soil away.
Answer: Without roots and leaves to protect it, soil is easily worn away.
Practice check
Have a go, then check your answers. Each answer comes with an explanation.
Answer guide for parents
Which type of tree forms most of Australia's forests?
Eucalypt — Eucalypts dominate most Australian forests.
Where do mangroves grow?
Along warm coastlines in salty water — Mangroves grow in salty coastal water.
How do plants help prevent erosion?
Their roots hold the soil together — Roots bind soil and reduce erosion.
Which type of vegetation is common in dry inland Australia?
Spinifex grassland — Spinifex grows in dry inland regions.
What is a habitat?
The natural home of a plant or animal — A habitat is where a living thing naturally lives.
Plants that grow naturally in a place are called ____ plants.
native — Native plants occur naturally in an area.
The wearing away of soil by wind or water is called ____.
erosion — Erosion removes soil and rock.
A dense forest with high rainfall and many layers of plants is a ____.
rainforest — Rainforests grow in high-rainfall areas.
Watch out for
- Children may think Australia's inland is empty of plants. Deserts and drylands support many hardy plants adapted to little water.
- Some think all fire is bad for vegetation. Many Australian plants are adapted to fire, and some need it to release seeds, although very intense fires can be destructive.
Tips for parents
- Visit a botanic garden or national park and look for different vegetation types.
- Learn about cultural burning and native plants from First Nations ranger programs, land councils or Aboriginal-run cultural tours in your area, rather than general sources alone.
- Encourage careful observation: leaf shape, bark type and where plants grow.
Go further
- Make a leaf rubbing collection from native plants in your area and label them.
- Grow a native plant from a seedling and record its growth.
- Research one animal and the vegetation it depends on.
