Challa Station Regeneration Project

Challa Station Regeneration Project is a Human-Induced Regeneration (HIR) project located on Challa Station, approximately 60km east of Mount Magnet in the Mid West (Southern Rangelands) region of Western Australia. It was registered in May 2018 and covers a vast 190,065.88 hectares, following minor area variations in 2020 and 2021 that removed select parcels of land.

Human-Induced Regeneration projects involve establishing permanent native forests by changing land management practices to allow in-situ seed sources (including rootstock and lignotubers) to naturally regenerate. To meet the scheme's standard requirements, the regenerating native trees must have the potential to reach at least 2 metres in height and 20% crown cover. In this project, the primary activity is carefully managing the timing and extent of livestock grazing to ensure regrowth, which had been suppressed for at least 10 years prior, can successfully mature.

The Mount Magnet area and the surrounding Southern Rangelands are predominantly used for extensive pastoralism (cattle and sheep grazing) and mining exploration. The environment is considered semi-arid to arid, experiencing low and highly variable rainfall. Soil types across the station generally consist of red sandy earths, shallow loams, and expansive areas of hardpan.

Challa Station has a rich pastoral history, having been operated by five generations of the Dowden family since 1888. The family famously transitioned the property from a Merino wool station to a Santa Gertrudis beef cattle enterprise after severe wild dog attacks decimated their flocks in the late 2000s. In early 2026, the Dowdens downsized and sold the property. The station, along with its carbon project, was acquired by the Australian environmental non-profit Forever Wild, operating under the entity Samphire Wild Pty Ltd. The carbon project had reportedly generated over 121,000 Australian Carbon Credit Units (ACCUs) prior to the acquisition.
