    Machinery is a major vector for seed dispersal of the exotic weed Cape broom. Contaminated vehicles and equipment are believed responsible for at least two large-scale infestations along gravel roads and numerous 'remote' infestations associated with telecommunication and power infrastructure in the Shire of Bridgetown-Greenbushes.

    Fire fighting and other emergency response vehicles also become significant vectors for the spread of Cape broom, with the added risk of transporting already heat-activated seed into remote and newly burnt areas.

    With the help of State NRM Program funding, this project aims to minimise the risk of shire and other stakeholders' vehicles and equipment spreading Cape broom seeds from infested sites to unaffected areas via soil transfer. This will be achieved through:

    • purchase and installation of mobile washdown equipment
    • establishment of Cape broom control areas
    • construction of strategic washdown bays
    • strategic removal of infested areas
    • education and dissemination of washdown procedures
    • provision of clean-down locations for other stakeholders, including Main Roads, private contractors, public utilities and other government agencies
    Investment: $ 12 200
    Delivery organisation: Shire of Bridgetown–Greenbushes
    Project duration: July 2011 - December 2012
    Location: Shire of Bridgetown–Greenbushes: degraded road and other reserve areas suitable for washdown water containment
