Tambua Regeneration Project

Tambua Regeneration Project is a Human-Induced Regeneration (HIR) project located at Tambua Station, approximately 50km west of Cobar in western New South Wales. It was registered in August 2015 and covers an extensive 57,460.55 hectares.

Human-Induced Regeneration projects involve establishing permanent, even-aged native forests by removing activities that suppress natural regrowth. For this methodology, standard requirements include ceasing mechanical clearing, managing livestock, or, as is the case for this project, controlling feral animals in a humane manner. This allows native trees to regenerate naturally from in-situ seed sources, rootstock, and lignotubers on land that was cleared and where regrowth was suppressed for at least 10 years prior to the project commencing.

The Cobar region is well known for its pastoral land uses, primarily cattle and sheep grazing for fine-quality wool. The area experiences a semi-arid climate with low and highly variable annual rainfall. Local soils generally consist of red earths, sandy loams, and clay loams.

Tambua Station has been owned and operated by the Evans family for over 100 years across five generations. Implementing this carbon project has provided the family with vital supplementary income to help overcome financial hardships, droughts, and bushfires. In January 2022, the project updated its methodology from Compilation No. 1 to Compilation No. 3. Its associated Commonwealth carbon contract (CAC102219) was successfully completed in July 2026. Public registry notes also highlight that the Clean Energy Regulator accepted Enforceable Undertakings related to this project from the agent Climate Friendly Pty Ltd (effective 2016 to 2017) and Australian Carbon Traders Pty Ltd (effective 2016 to 2018).
