Milly Milly and Berringarra Station

Milly Milly and Berringarra Station is a Human-Induced Regeneration (HIR) carbon project located in the remote Murchison region of Western Australia, approximately 170km northwest of Meekatharra. Registered in March 2022, the project spans an immense area of 448,327 hectares, covering the historic pastoral leases of Milly Milly and Berringarra. The region is traditionally dedicated to pastoralism, specifically sheep and cattle grazing, and is known for its vast, arid landscapes characterized by low hills, mesas, and flood plains associated with the Murchison River.

The project operates under the Human-Induced Regeneration methodology, which differs from tree planting projects. Instead of manually planting seedlings, this method relies on managing the timing and extent of grazing to remove suppression pressures on native vegetation. By controlling livestock and feral animals, the project allows existing native seed sources, rootstocks, and lignotubers to regenerate into permanent, even-aged native forests. To qualify, the land must have been suppressed of forest cover for at least 10 years prior to the project's commencement and must show potential to reach forest cover (20% canopy density at a height of 2 meters).

Environmentally, the Murchison region is classified as arid to semi-arid with a median annual rainfall of approximately 200mm to 250mm, which falls predominantly in winter but can be irregular. The terrain features red earth, sandy loams, and shallow stony soils that support vegetation types such as Mulga woodlands and saltbush shrublands. The project proponent, AI CARBON WA NO.2 PTY LTD, is a subsidiary of Australian Integrated Carbon, a developer that partners with landholders to generate Australian Carbon Credit Units (ACCUs). Interestingly, the Shire of Murchison, where the project is situated, describes itself as the "Shire without a town," having no gazetted townsite and relying on station settlements for population hubs.
