10002: Invasive weed eradication within Beeliar Regional Park
Beeliar Regional Park nature reserves on the campus of Murdoch University consist of two conservation category wetlands (melaleuca swamp and chelodina wetland) and a banksia woodland.
All three reserves were nominated for Bush Forever and are regionally critical habitat for Carnaby's and forest red-tailed black cockatoos, and quendas (bandicoots).
Arson, rubbish-dumping and four-wheel driving has spread invasive weed species throughout the reserves causing significant habitat degradation and erosion of biodiversity values.
With the help of State NRM Program funding, this project aims to eradicate highly invasive weed species from the reserves.
On-ground works include treatment of arum lily, pampas grass, and blackberry within melaleuca wetland; control of a runaway veldt grass invasion within arson sites at banksia woodland, chelodina wetland and wildlife corridor; and removal of spot infestations of bridal creeper, Victorian tea-tree, African lovegrass and couch.

Major project achievements
- Extensive veldt grass weed treatment was completed in the Banksia Woodland. Spraying was complimented by manual seed head removal by Bush Ranger volunteers.
- Bridal creeper tubers and stems were removed by hand at two key sites in the Wildlife Corridor. Monitoring was undertaken in spring, with no new regeneration sighted.
- Spraying of couch and buffalo grass infestations was completed around the perimeter of Melaleuca Swamp.
- Spraying of arum, pampas and blackberry was completed in Melaleuca Swamp target areas. Good kill rates for pampas and blackberry in target areas were achieved; arum requires ongoing treatment (which has been funded in 2013).
- Victorian tea tree was removed around the perimeter of the Chelodina Wetland. Monitoring was subsequently undertaken in spring, with no further removal required at this time.
- Fig and pepper trees were baselbarked in Melaleuca Swamp.
