15101: Dieback and Weed Management for Bungendore Park and adjacent land.
Importance - Bungendore Park is a relatively large reserve
of 498 ha, mostly in excellent condition, which forms an important
green peri-urban backdrop to the City of Armadale. Two declared
rare orchids and numerous priority flora can be found in the park
which contains six major habitat types over the Darling Scarp
geology of the park. Bungendore Park is listed as a Jarrah
Reference Site (JF5) for the Perth Region Plant Biodiversity
Project and is also an important study site of the three endangered
Black Cockatoos by the WA Museum. A Vertebrate Fauna of Bungendore
Park report was published in November 2014 of the observational
data and pit traps surveys conducted in the park since
Phytophthora Dieback has infected approximately 281 hectares of Bungendore Park. The potential impacts of Dieback on Bungendore Park's values include the death of up to 40% of the floral species diversity through direct susceptibility of these species to the Phytophthora pathogen. The long-term risk is further loss of flora (and potentially partnered-fungi) that is not directly susceptible to Dieback that is also likely due to changes in biophysical conditions resulting from the death of susceptible species.
Weeds in Bungendore Park are mostly confined to disturbed areas where weeds have been introduced e.g. rubbish dumped many years ago and some weed control is undertaken. On land adjacent to the park there are many areas with multiple weed infections; the long-term risk is weed species incursion into bushland in excellent condition. Committee is focusing its efforts on weed control to prevent this happening.
Project activities -
1. 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 (due to vectors or due to conservation significance within the park). Treatment will include Phosphite application by tree trunk drilling and injection with syringes and foliar spraying of understorey plants and trees too small to be injected. Soil and plant tissue sampling to isolate and treat new pathogen outbreaks as they are discovered. GIS map information will be updated following the treatment.
2. Undertake chemical control of weeds in newly treated areas and to use manual removal of emergent plants in formerly treated areas and where chemicals cannot be used. A community Walk and Weed event will be held in the Spring of 2016
3. Produce a colour information pamphlet with a covering letter informing of the environmental enhancements covered by this project and post to park neighbours.
This project is important as it addresses two of the major key threatening processes on the biodiversity of Bungendore Park and adjacent land.
