Wetlands are areas of marsh, fen, peatland or water,
whether natural or artificial, permanent or temporary, with water that
is static or flowing, fresh, brackish or salt, including areas of
marine water the depth of which at low tide does not exceed six
metres.
Wetlands are a vital element of national and global ecosystems and
economies. At the most fundamental level, wetlands are a key part of
the water cycle, playing critical roles in maintaining the general
health of Australia's rivers, estuaries and coastal waters. Wetlands
protect our shoreline from wave action, mitigate the impacts of
floods, absorb pollutants and provide habitats for animals and plants,
including a number of species that are threatened or endangered.
Wetlands are also critical to maintaining and improving our quality of
life. They provide tangible benefits to the Australian economy, such
as employment opportunities. Wetlands purify our water and are a
focal point for recreational activities. They form nurseries for fish
and other freshwater and marine life and as such are of critical
importance to Australia's commercial and recreational fishing
industries. In some areas, wetlands support grazing, forestry and
cropping.
Despite a growing understanding of their many values and functions,
wetlands remain one of our most threatened resources. They continue to
be regarded by many as wastelands and their destruction
continues. Where wetlands were once abundant, they have been destroyed
or altered, without recognition of the long-term impacts these actions
will have on our quality of life.
