Mulganey Regrowth Project

Mulganey Regrowth Project is a human-induced regeneration project located approximately 30km west of Wanaaring in outback New South Wales. It was registered in August 2015 and covers an area of 8,505.04 hectares.

Human-induced regeneration (HIR) projects involve establishing permanent, even-aged native forests by altering land management practices to assist regeneration from in-situ seed sources, such as rootstock and lignotubers. Projects under this methodology must demonstrate that regrowth was suppressed for at least 10 years prior to commencement, and they are required to achieve standard milestones, including a minimum 20% canopy cover and a forest height of 2 metres. The primary project activities here focus on strictly managing the timing and extent of livestock grazing, alongside the humane management of feral animals, to relieve suppression pressures on native vegetation.

The Wanaaring area, situated within the Unincorporated NSW local government area, is traditionally known for extensive pastoral operations, specifically sheep and cattle grazing. The regional environment is classified as semi-arid, experiencing very hot summers and a low, variable average annual rainfall of approximately 200 to 400mm. Soils in this outback rangeland generally consist of shallow red earths, clay loams, and patches of siliceous gravel, which are typical of the broader Mulga lands.

This project was established to restore permanent native vegetation on historically cleared land while balancing pastoral pressures. In November 2015, the proponent successfully secured a Carbon Abatement Contract (CAC102622) with the Commonwealth, committing to a fixed delivery of 90,174 ACCUs. By mid-2026, over 68,000 ACCUs had already been delivered and sold to the Commonwealth under this agreement. Additionally, the project's methodology was updated in August 2023 to align with Compilation No. 3 of the relevant 2013 determination.
