Floodplain wetlands of the Murray-Darling Basin and their freshwater biota

Chapter


Abstract


  • In inland Australia, remarkable wetlands occur in low-lying and often extensive areas of floodplain

    that are subject to inundation by freshwater from rivers and creeks. These floodplain

    wetlands provide critical aquatic and riparian habitat for flood-reliant and flood-tolerant flora

    and fauna, collectively termed biota, in otherwise semiarid or arid landscapes. This diverse

    range of plants, animals and microscopic organisms, including endemic and threatened

    species, occupy habitats and ecological niches that are created and maintained by the flows and

    flood regimes of the floodplain wetland systems in which they survive and flourish. These

    ecosystems are naturally variable and are characterised by complex interrelationships between

    their flood patterns, landforms and soils, and ecological communities. The flow regimes of

    inland Australian rivers are driven by weather and climate variability, and so inland floodplain

    wetlands experience changes in the frequency, magnitude and duration of flooding in

    response to cycles and extreme events of rainfall and runoff in their catchments. Like the

    impacts of land use and water resource development in our river catchments today, future

    climate change related to human-induced global warming is likely to compound the effects of

    natural climate and hydrological variability, potentially altering the balance of biophysical and

    ecological processes in many of Australia's rivers and iconic floodplain wetlands.
