Project Description

The Mallee emu-wren (MEW) has been identified as a Fighting Extinction Species in ZV’s Wildlife Conservation Master Plan 2019-2024 (WCMP), due its urgent conservation situation. The MEW is restricted to a small number of populations, and these populations are to the significant risks posed by fire. An increase in the number of populations is essential to countering the high risk of extinction of this species.
Following local extinction in South Australia due to bush fires, a first phase translocation of the species was successfully conducted in 2018. Seventy-eight birds were transferred from Murray Sunset National Park and Hattah-Kulkyne in Victoria to Ngarkat Conservation Park in SA. ZV plan to support further wild-to-wild translocations within the former range of the MEW as part of the WCMP.
This grant will support research into the genetic diversity and differentiation of the Wyperfeld Mallee emu-wren population, and the potential of this population as a source of diversity for translocated populations into the adjacent Ngarkat Conservation Park. This grant will also support population monitoring at translocation source and release sites in Spring 2019 and 2020 to evaluate the success of translocations and any impacts on source populations. This will involve both visual observation surveys and the use of acoustic recording units (ARUs), which will also serve as an assessment of the effectiveness of ARUs for monitoring the species.
Objectives
This project’s objectives are to assess the genetic diversity and differentiation of the Wyperfeld mallee emu-wren population and to conduct monitoring at translocation source and release sites.
Specific objectives of the grant:
a) Genetic Sampling of Mallee Emu-wrens in Wyperfeld/Big Desert
b) Mallee Emu-wren population monitoring at translocation source and release sites
