14040: Control of significant outlier infestations of strategically important WONS

    Opuntia elatior is a cactus species that poses a significant threat to native landscapes in the north-west. The largest plants are up to four metres tall and over seven meters wide. The bulk and size of the larger plants crowds out native flora and restricts access to watering points for birds, kangaroos and other local wildlife.

    An infestation of the weed currently covers over 1000ha of Wydgee Station in Mount Magnet and is slowly spreading along a creek-line and into adjacent land.

    Investment: $ 30 000
    In-kind contribution: $ 18 265
    Delivery organisation: Rangelands Fibre and Produce Association
    Project duration: April 2015 - April 2016
    Location: Wydgee Station, Great Northern Highway Via Mount Magnet WA 6638; Shire of Yalgoo

    Purpose of project

    Building on previous work conducted by the group to restrict further spread of the invasive cactus, this project will concentrate on treating the remaining "core" of the infestation with the long-term aim of eradication.
