    Watsonia is one of the most destructive weeds in the eastern hills. It has been identified in the Shire of Mundaring's weed control strategy and integrated catchment management plan as one of the top 10 weeds to control and eradicate.

    Distribution of watsonia has been recorded in the shire's roadside conservation survey. The most significant infestations within the Jane Brook catchment have been identified near the town sites of Mt Helena, Mundaring, Stoneville and Parkerville.

    Roadside vegetation has also been categorised as part of the survey into high, medium and low conservation values. Roadside vegetation provides important wildlife and biodiversity corridors within the shire and weed control is essential to retain these values.

    With the help of State NRM Program funding, this project focuses on eradicating watsonia that has established throughout the Jane Brook catchment.

    Follow-up control will be conducted on priority areas that are affecting sites through boundary infestation from neighbouring remnant bushland. The project will also target follow-up control and revegetate sites where watsonia has been successfully controlled.

    Investment: $ 17 000
    In-kind contribution: $ 19 612
    Delivery organisation: Shire of Mundaring
    Project duration: July 2011 - September 2012
    Location: Shire of Mundaring

    Major project achievements

    • Watsonia reduction (70%) and other weed control was achieved on over 13.5km throughout the Shire of Mundaring.
    • Seedlings (>2, 900) planted throughout the shire.
    • Increased floral biodiversity.
    • Community participation was successful, with over 280 hours of volunteer time.

    Lessons Learnt

    • Shire input (monetary) to the projects would have reduced spending and necessary funds would have assisted in additional weed control and a better project outcome.
