Abstract
The Byford Rail Extension (BRE), which is part of several METRONET projects of the Public Transport Authority of Western Australia (PTA), will connect Armadale to Byford over a distance of ~8 km. As part of the BRE construction, the current Wungong Brook bridge will be replaced by a new bridge that will fully span Wungong Brook with no requirement for an in‐river pier (location shown in Figure 1). Environmental approval has been granted by State (Ministerial Statement 1183) and Commonwealth (EPBC 2020/8764) governments.
Carter’s Freshwater Mussel (Westralunio carteri) was located within the Wungong Brook including the BRE footprint in September and October 2020 (Stream Environment and Water 2021; Figure 1). That survey indicated a self-sustaining population was present as indicated by the existence of a range of size classes. Bridge construction for the BRE across Wungong Brook has a potential to impact this mussel population.
Westralunio carteri is listed as Vulnerable under the Biodiversity Conservation Act 2016 (BC Act 2016), the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act 1999) and IUCN Redlist. Protection of remaining populations is necessary and accordingly, approval of the BRE is conditional upon development and implementation of a Carter’s Freshwater Mussel Translocation Plan.
