    The North Kimberley coastal area incorporates the Balanggarra Native Title Claim, a national biodiversity hotspot, and the Berkeley River, King George River, Cape Whiskey Creek and Londonderry Creek, all categorised as pristine or near-pristine wild rivers.

    Infestations of the declared plant calotropis (rubber bush) have been identified at the mouth of the Berkeley River and near Bertram Cove. The air-filled seed pods of this weed are likely to be spread by floating on tidal currents or winds and are landing on beach fronts. The 4 m high poisonous shrub can be hazardous to humans, can change the composition of native plants, and can threaten nesting of sea turtles in the coastal area.

    This project aims to eradicate calotropis from the Kimberley coast and monitor other weeds in the process.

    Investment: $ 106 000
    Delivery organisation: Kimberley Land Council
    Project duration: September 2010 - September 2011
    Location: North-East Kimberley Coast between Wyndham and Kalumburu
