About Wetlands

What are wetlands?

Wetlands are areas of land where water covers the soil – all year or just at certain times of the year. They include:

  • swamps, marshes
  • billabongs, lakes, lagoons
  • saltmarshes, mudflats
  • mangroves, coral reefs
  • bogs, fens, and peatlands.

Wetlands may be natural or artificial and the water within a wetland may be static or flowing, fresh, brackish or saline. There are even underground wetlands.

Why are wetlands important?

Wetlands are a critical part of our natural environment. They protect our shores from wave action, reduce the impacts of floods, absorb pollutants and improve water quality. They provide habitat for animals and plants and many contain a wide diversity of life, supporting plants and animals that are found nowhere else.

Wetlands provide an important range of environmental, social and economic services. Many wetlands are areas of great natural beauty and many are important to Aboriginal and Torres Strait Islander people.

Wetlands also provide important benefits for industry. For example, they form nurseries for fish and other freshwater and marine life and are critical to Australia's commercial and recreational fishing industries.

Wetlands are the vital link between land and water.

Australia's wetlands

Australia has 66 Ramsar wetlands that cover more than 8.3 million hectares. Ramsar wetlands are those that are representative, rare or unique wetlands, or are important for conserving biological diversity. These are included on the List of Wetlands of International Importance held under the Ramsar convention.

All Australia's internationally and nationally important wetlands are listed on the Australian Wetlands Database.

Learning about wetlands

More information about wetlands, including links to educational resources, publications and a list of Australian wetland education centres, is located on the Communication, Education, Participation and Awareness Program page.
