Nature Conservation partners with DBCA on arum lily control

Following support from the Minister for Environment, planning is currently being undertaken to improve strategic management of arum lily in the Margaret River region. Staff are collaborating with the Department of Biodiversity, Conservation and Attractions to develop a framework for management across all tenures. Following development of the management framework, other stakeholders will be engaged and resourcing sought to implement a major collaborative campaign to address this invasive weed.

Weed management plans and priority control

Nature Conservation continues to undertake strategic weed management planning and priority control in accordance with the Capes Regional Environmental Weed Strategy developed in 2015.  The Capes Regional Environment Weed Management Group (CREWG) is coordinating priority control and community awareness raising activities across organisations and tenures.

Five management plans for priority emerging weed species and five for widespread weed species have now been completed and reviewed by CREWG members. Weed control programs in accordance with these management plans are currently funded by the State NRM program on a cost sharing basis with landowners, the Shire of Augusta Margaret River and the Department of Biodiversity, Conservation and Attractions.

The 2017 arum lily control program successfully engaged 300 landowners across approximately 3000 hectares. Control focused again in the Redgate, Calgardup, Kilcarnup, Burnside, Cullen Rd/Juniper Rd areas as well as extending landowner engagement on the south side of lower reaches of the Margaret River. The 2018 arum control program will commence in July 2018. The annual blackberry control has recently been completed including control in the Margaret River foreshore reserve and 11 private properties in the catchment. Control of other priority species such as African feathergrass, dolichos pea and pittosporum is ongoing.

Community urged to control weedy wattles

Landholders are urged to control spreading weedy wattles that are threatening biodiversity in the Margaret River area.

Many wattle species native to eastern Australia have been widely planted in rural residential areas in the Margaret River region in gardens, windbreaks and revegetation. Whilst planted with the best intentions and following advice provided at the time, we now know that these plants are very invasive and are spreading throughout bushland areas where they reduce the variety of native plants and animals. They also increase the fuel load in the bush and the risk of fire.

Control methods
Wattle species can be controlled all year round by the following methods:
Hand weed. Be wary of soil disturbance and trampling. Suitable for light infestations of many seedlings and small saplings, not suitable for suckers
Felling and ringbarking. To ringbark, cut away a strip of bark at least 10 cm wide and deep enough to sever the flow of plant food up the trunk. When felling, cut as close to the ground as possible to minimise the probability of reshooting.
