This project aims to preserve the grey range thick-billed grasswren in the Milparinka and Packsaddle areas of the downs country in the far west rangelands.
The Threatened species – grey range thick-billed grasswren project will:
- address habitat loss caused by soil erosion
- improve the habitat of the grey range thick-billed grasswren and other threatened species of the rangelands.
Project background
The grey range thick-billed grasswren is one of the most critically endangered bird species in NSW. It was considered extinct in north-west New South Wales until sightings of a small number of birds during 2008.
This project builds on previous successes in rehabilitating the habitat of the downs country for various species.
Grey range thick-billed grasswren facts
- Scientific name: Amytornis modestus obscurior.
- Threat level: critically endangered.
- Preferred habitat: bluebush shrubland on stony rises and downs in the arid and semi-arid zones.
- Features: small, short wings built for hopping between bushes and grass tufts rather than long flights.
- Known locations: far north-west of NSW.
Project objectives
Aims of the project:
- address habitat loss caused by soil erosion
- improve the habitat of the grey range thick-billed grasswren and other threatened species of the rangelands.
A diverse range of animal and plant species are set to benefit from the work.
The work in this project requires a long-term view. The areas we’re working in don't typically get a lot of rain. It could be 2 to 3 years after the earthworks, in good growing conditions, before the land recovers and the vegetation begins growing back. This attracts the species back into the landscape.
By the end of the project on 30 June 2028, we expect the landscapes at selected work sites to show strong signs of recovery. This recovery includes the return of more plant and animal species to these areas.
Project delivery
Work includes:
- rangeland rehabilitation earthworks to rehydrate the landscape, reduce erosion and provide opportunity for grasswren habitat to regenerate
- monitoring of grey range thick-billed grasswrens and land systems
- Aboriginal cultural heritage surveys
- incorporating the knowledge of Traditional Owners into the project
- enhancing awareness of the species within the landholder community.
Project timeline
2024:
- site identification through vegetation mapping
- fauna survey
- Traditional Owner consultation
- Aboriginal cultural heritage assessment of the planned work sites
- contour assessment and marking out in preparation for on-ground works
- landholder discussions on planned works.
2025–27:
- site selection (4 sites) for year 2 commences early 2025 with earthworks commencing mid to late year
- community consultation will occur late 2025 for another 8 properties
- site selection (4 sites) for year 3 commences early 2026 with earthworks commencing mid to late year
- survey and monitor first 7 sites for improvement and outcome reporting
- site selection (4 sites) for year 4 commences early 2027 with earthworks commencing mid to late year.
2028:
- fauna survey (landscape recovery monitoring)
- Traditional Owner and landholder field days
- project close (30 Jun 2028) and outcomes reporting.
Work underway
Building on the success of the previous 12 months, a new year of activities has commenced, including:
- the selection of rangeland rehabilitation works for 4 new sites on private landholder properties covering 236 ha
- habitat condition surveys to establish a baseline vegetation condition across rangeland rehabilitation sites
- Aboriginal cultural heritage assessments of these 4 sites prior to on-ground works commencing.
Project updates
Works to date include:
- community event to raise awareness of the project with landholders
- rangeland rehabilitation works at 3 sites, covering 177 hectares
- Aboriginal cultural heritage assessments conducted at the on-ground works sites
- fauna study, establishing a baseline for the project, along with an on-site fauna survey demonstration with local community members
- baseline habitat condition surveys completed at 3 sites to monitor change in vegetation following the completion of rangeland rehabilitation works
- two-day tour of known grasswren habitat for Traditional Owners, providing opportunity to connect with Country.
