    Ramsar sites are wetlands of international importance. Toolibin Lake in the WA wheatbelt is Ramsar-listed and Lake Bryde in the southern wheatbelt is listed in the Directory of Important Wetlands in Australia.

    Both wetlands contain unique ecological communities and are under threat from changes to surface water hydrology, in particular waterlogging and salinity.

    Through this project, the Department of Environment and Conservation worked with the community to implement extensive engineering works to control surface water and recover the natural diversity of the lakes and their catchments.

    Investment: $ 480 000
    In-kind contribution: $ 55 000
    Other contribution: $ 50 000
    Delivery organisation: Department of Environment and Conservation
    Project duration: October 2009 - March 2011
    Location: Toolibin Lake and Lake Bryde natural diversity recovery catchments

    Major project achievements

    • Stage 1 earthworks completed on the western boundary of Lakeland Nature Reserve. This will reduce waterlogging of highly valued melaleuca thickets and reduce the salt build-up on the soil surface through evaporation. Data loggers will provide a monitoring network to test the effectiveness of these structures.
    • Main waterway completed through Lakelands Nature Reserve, improving surface water flow through the valley floor of the Lake Bryde recovery catchment.
    • Inlet and outlet controls at Toolibin Lake completed, improving surface water management.
    • Rehabilitation and revegetation of degraded areas in the Toolibin Lake catchment completed.
    • Monitoring transects at Lake Bryde established, forming the basis for regular monitoring to assess long-terms trends of soil salinity and vegetation condition along the waterway.
