Byro Station, Murchison HIR Aggregation

Byro Station, Murchison HIR Aggregation is a Human-Induced Regeneration (HIR) project located at Byro Station in the Shire of Murchison, Western Australia, approximately 100km north of the Murchison Settlement. It was registered in August 2020 and covers an expansive 227,058.94 ha.

Human-Induced Regeneration projects involve establishing permanent native forests through assisted regeneration from in-situ seed sources, such as rootstock and lignotubers. The methodology requires the land to have been cleared of vegetation and for regrowth to have been suppressed for at least 10 years prior to the project commencing. Standard activities to achieve regeneration include the exclusion or careful management of livestock grazing, as well as the humane management of feral animals, allowing the land to naturally recover.

The Murchison region is traditionally known for large-scale pastoral operations, primarily sheep and cattle grazing. The environment is classified as semi-arid, experiencing hot summers, cool winters, and an average annual rainfall of approximately 250mm. Soils in the area generally consist of red sandplains, calcareous soils, and red loams along ancient drainage lines.

This project is notable for its massive scale and historical context. Byro Station is a historic pastoral lease originally settled in 1874, making its transition into a carbon farming initiative a significant shift in rangeland management. In June 2025, the project underwent a variation, transferring the proponent from Australian Integrated Carbon Financial Services Pty Ltd to Emissions Abatement Solutions (WA) Pty Ltd.
