15009: Strategic biosecurity intervention for the containment of cleavers
Cleavers (Galium aparine) is a new highly invasive declared weed with potential to infest extensive areas of the Southwest.
Cleavers is spread by animals, machinery and water, is a highly
competitive plant that replaces native vegetation by smothering and
producing allopathic chemicals that inhibit recruitment of existing
Identified as a few isolated sleeper infestations east of Bridgetown in 2004, cleavers now infest up to 20km of the Blackwood River and tributaries, 15km of roadside and 2.5km2 of crown land and private property, with the potential to impact two nearby national parks and key natural ecosystems and affect nearby agricultural areas.
This project will:
- equip the Blackwood Biosecurity Inc. and Shire with an integrated GIS mapping and Declared Pest reporting platform for collection, and utilisation of weed mapping data;
- collaborate with WALGA via the "Environmental Planning Tool" Team and DAFWA through the "Agricultural weed surveillance in the South West to effectively map, control and monitor outlier infestations and the containment of existing Galium aparine infestations;
- engage other land managers and stakeholders to reduce the rate of spread and degree of seed bank contamination of Galium aparine within the currently infested areas via coordinated multi stakeholder herbicide application.
