Current Projects

The Centre and its member groups implement annual restoration works and trials in the Beeliar Regional Park.

Annual revegetation projects date back to 1985 when the Wetlands Conservation Society first formed. Five to ten thousand plants are established per annum in wetland and bushland areas.

Connecting North Lake and Frog Swamp, North Lake Reserve

This site was used as a horse agistment area in the past and the soils are very degraded. Although the weeds were not lush, the site supported annual grasses, pigface and perennial couch. The Wetlands Conservation Society received funding during 2006 through the Regional Park Community grants provided by the Regional Parks Unit of the Department of Environment and Conservation to establish 1,000 seedlings and a bore for revegetation purposes. The bore was established in the superficial aquifer and a portable pump, layflat hoses and 35 mm hoses are used to water the site. The bore will support annual revegetation efforts for years to come. Previous trials comparing reticulated establishment, Carroll tree tubes, seedlings and mature plants, mulch have shown consistent results were only obtainable using watering during the establishment phase.

The corridor, Bibra Lake Reserve

This site was cleared for grazing purposes and represents the shortest link between the wetland foreshore and the vegetated uplands. Overstorey plantings and transplanted zamias and grasstrees were established in previous years. During 2005, 1,200 understorey plants were established and a further 800 during 2006. Conservation Volunteers and BHP Billiton assisted with the plantings. The Centre staff and volunteers have just completed a 2-year summer watering and weeding program on the 2005 site. The Centre provided funding and labour for ongoing maintenance for the site.

Fertiliser trials to compare survival rates and growth using a control with tree tablets, organic fertiliser and granulated fertiliser were incorporated into the 2005 site. Monitoring of the results will occur at the end of the 2007 summer period.

Adjacent to the site existed a large stand of the introduced Melaleuca nesophila that supported an extensive warren for the introduced European Rabbit. Tree guards had to remain intact due to the heavy predation of the seedlings. Volunteers and staff have removed the Melaleuca with bowsaws and chainsaws and destroyed the warren. City of Cockburn removed the weed from the site.
