    Denbarker was a war-settlement town established west of Mt Barker in a mixed farming district. Many properties are now growing blue gums, with existing houses and associated gardens left unoccupied.

    'Garden escapees' have proliferated as a result, threatening the biodiversity of bushland remnants on private properties and in nearby reserves and national parks. Eastern states' wattles (mainly Sydney golden wattle) are of particular concern, showing significant invasive potential.

    With the help of State NRM Program funding, this project will map the distribution of the wattles before treatment to ensure effective planning of weed control and follow-up treatment. Weeds will be removed manually around springs and waterways, and by basal bark sprays in non-sensitive areas. About 500 ha of weeds will be controlled through this project.

    Managers of surrounding blue gum plantations will be engaged to participate in the project. The Denbarker community and Pardelup Prison work crews also will participate to enable cost-effective weed control activities to be undertaken.

    Investment: $ 50 000
    Delivery organisation: Wilson Inlet Catchment Committee
    Project duration: January 2012 - December 2013
    Location: Denbarker, a war settlement town west of Mt Barker
