    Rubber vine is a weed of national significance. It is currently known to be present at two locations in the Kimberley-on the Fitzroy River and on the Ord River. The plant smothers riparian vegetation and forms dense, sometimes impenetrable, thickets. This decreases biodiversity and prevents access to both stock and native animals.

    With the help of State NRM Program funding, this project will eradicate rubber vine from 1000 ha along the Ord River. It will also contribute to the control of other weeds of national significance and declared weed species on 23 existing sites covering 1655 ha of riparian land on the Lake Kununurra Ramsar site.

    Investment: $ 50 000
    Other contribution: $ 123 600
    Delivery organisation: Ord Land and Water
    Project duration: July 2011 - December 2012
    Location: Lake Argyle and Lake Kununurra

    Major project achievements

    • Weed,Cryptostegia grandiflora,control was successful to 1, 876ha on Lake Argyle Downs and Lissadell Station.
    • Existing sites on Lake Kununurra were further treated and 5 sites (65ha) had their status reduced from 'active' to 'monitored'.

    Lessons learnt

    • Aerial burning of mature plants was not successful (fuel mix was incorrect).

    • Inadequate surveying and monitoring underestimate the spread and density of the infestation.

    • Fire occurrence prohibited control work in the short term, but in the long term improved access and possibly assisted with removal.

    • Adequate monitoring, mapping, communication and understanding of the project will reduce project inefficiency.
