Chief refuge value
A massive complex of wetlands providing a wide range of habitats and a major drought refuge for waterbirds.
The Paroo River and Cuttaburra Creek, together with the Warrego River, run south-west from the Queensland border towards Wilcannia, carrying occasional floodwaters through a reticulate system of broad, shallow distributary channels and draining into overflow swamps and terminal playa lakes1, 2, 3, 4. The channels and swamps are densely vegetated with lignum Muehlenbeckia cunninghamii and eucalypts and acacias. Associated with the system are salinas, such as Utah Lake, which experience short-term inundation from local run-off3. Major flooding takes place on average about once every five years; the persistent water supports large populations of breeding and refuging waterbirds3, 5.
Other significant species
The huge populations of waterbirds that use the wetlands3. The freckled duck Stictonetta naevosa occurs3.
Changes to hydrology and vegetation springing from over-grazing on surrounding pastoral land.
