    The Quininup Falls are home to the threatened Leeuwin snail and an endangered threatened ecological community of tufa (limestone), which are geological structures created by microbial communities that rely upon freshwater springs. Communities of both the snail and tufa are directly influenced by water quality.

    Water quality analyses have detected high nutrient levels in the catchment, which threaten both the snail and tufa. The falls are regularly covered in macro algae suggesting ongoing water quality issues.

    With the help of State NRM Program funding, this project will engage public and private land managers to better understand the condition of Quininup Brook and threats to its health from excessive nutrients.

    It will address key threats through on-ground actions in the riparian zone including:

    • weed control
    • fencing
    • revegetation.

    Information collected from condition assessments will be mapped and property-specific actions to protect and enhance the brook will be prioritised in a report provided to all land managers.

    Investment: $ 48 760
    Delivery organisation: Cape to Cape Catchments Group
    Project duration: July 2011 - September 2012
    Location: Quininup Brook, 30 km south-west of Busselton
