10005: Dieback treatment and weed control, Bungendore Park and adjacent land
Bungendore Park is a relatively big reserve of 498 ha that is mostly in excellent condition. Since 1981 a community-based committee has managed the area as a conservation reserve.
Two declared rare orchids and numerous priority flora can be found in the park which contains six major habitat types over the Darling Scarp.
The reserve is an important study site of the three endangered black cockatoos (Baudin's, Carnaby's and forest red-tail) and is listed as a 'jarrah reference site' for the Perth Region Plant Biodiversity Project.
About 280 ha of Bungendore Park is infected with dieback disease. The potential impact of dieback includes the death of up to 40 per cent of the floral species directly susceptible to the pathogen. Further loss of flora (and potentially fungi) not directly susceptible to dieback is also likely due to changes in biophysical conditions resulting from the death of susceptible species.
With the help of State NRM Program funding, this project aims to undertake actions to minimise the further spread of dieback and to treat those areas of dieback-free vegetation that are at high risk of infection.
Treatment will include tree-trunk drilling and injection with syringes, and foliar spraying of understorey plants and trees too small to be injected. Chemical control of weeds will be undertaken in newly treated areas and manual removal of emergent plants in formerly treated areas will be undertaken where chemicals cannot be used.

Major project achievements
- 7.4 ha of dieback-free vegetation at high risk of infection were treated with foliar sprays and stem injections of Sprayphos 620.
- 30 ha of weeds were sprayed and manually removed.
- Two information pamphlets (Fighting Dieback and Weed Control) were posted to park neighbours and wider community of Bedfordale (400 residents in total).
Community information distribution was increased, but had no major effect on the volunteer attendance.
Unanticipated weather delayed spraying and extended the time of the project.
