Wetlands

Wetlands within the Northern Agricultural Region are critical sites of surface and groundwater interaction, acting as collection points for surface water runoff and providing recharge to groundwater.

In the NAR, many wetlands dry out completely during the summer but there are some which are continuously fed by groundwater which are extremely important transitory habitats for migrating birds as well as supporting significant permanent aquatic ecologies. The habitats in and around the wetlands of the NAR are highly sensitive to water chemistry changes caused by land use practices as well as changing hydrology from both land use and climate change leading to altered water regimes.

There are eight wetlands in the NAR that are listed on the Directory of Important Wetlands (Environment Australia, 2001). These wetlands are recognised as being Nationally significant

In addition, five wetlands were listed as being sub-regionally significant in WA’s biodiversity Audit (Desmond and Chant, 2003) along with the wetlands described in the wetland atlas for the Swan Coastal Plain. Find out about these wetlands on the map below.
