Challa Station Regeneration Project

Challa Station Regeneration Project is a Human-Induced Regeneration (HIR) project located at Challa Station near Mount Magnet, approximately 600km northeast of Perth in the Murchison region of Western Australia. It was registered in May 2018 and covers approximately 190,065 hectares, though the project area saw minor administrative variations in 2020 and 2021 to remove some land segments.

Human-Induced Regeneration projects involve establishing permanent, even-aged native forests through assisted regeneration from in-situ seed sources, such as rootstock and lignotubers. This methodology is applied on land that was previously cleared of vegetation and where regrowth was suppressed for at least 10 years prior to the project commencing. For this specific project, regeneration is facilitated by carefully managing the timing and extent of livestock grazing to allow the native vegetation to recover.

The Mount Magnet and broader Murchison region is traditionally a vast pastoral area heavily utilized for grazing. The regional environment is classified as semi-arid, characterized by low, variable rainfall and hot dry summers, with soils generally consisting of red sandy earths, hardpan loams, and scattered clay plains.

Historically, Challa Station was owned and operated by Ashley and Debbie Dowden, who ran a commercial Santa Gertrudis cattle operation on the property. In early 2026, the project proponent was formally varied to Samphire Wild Pty Ltd. This change aligned with reports that the Australian conservation non-profit Forever Wild acquired Challa Station in January 2026 to focus on long-term ecological preservation. The carbon project has been highly productive, generating over 121,120 Australian Carbon Credit Units (ACCUs) since its inception and successfully delivering on a fixed delivery Carbon Abatement Contract.
