    The Blackwood River has endemic freshwater aquatic fauna, with 80 per cent of fish and all crayfish within the river's catchment found nowhere else in the world.

    Unfortunately, increasing salinity has restricted the habitat of many species to the more heavily forested tributaries in the lower catchment.

    Carrolup River, which flows through Marribank Farm, is a tributary that directly affects water quality downstream. The farm, also known as Carrolup Mission, is significant to Aboriginal history and home to a suite of declared rare flora species and priority species. However, it is under threat from salinity, weed infestation and loss of biodiversity.

    With the help of State NRM Program funding, this project will provide habitat for fauna through revegetation of riparian areas and the creation of a habitat corridor linking 150 ha of pristine remnant vegetation to 500 ha of bushland along the Carrolup River. This will also help alleviate the effects of salinity downstream.

    Priority weeds such as bridal creeper and Cape tulip that have spread beyond the river area onto the farm will also be controlled.

    Investment: $ 38 000
    Delivery organisation: Southern Aboriginal Corporation
    Project duration: October 2011 - December 2012
    Location: Marribank Farm, 20 km north-east of Kojonup
