Ballythunna Station, Murchison HIR Aggregation

Ballythunna Station, Murchison HIR Aggregation is a Human-Induced Regeneration project located in the Murchison region of Western Australia, approximately 200km inland from the state's mid-west coastline. It was registered in August 2020 and covers an expansive 124,833.49 hectares.

Human-Induced Regeneration (HIR) projects involve establishing permanent native forests by actively stopping activities that suppress vegetation growth, allowing the land to naturally repair itself. For this specific methodology, standard requirements dictate that the native forests must be established through assisted regeneration from in-situ seed sources (such as rootstock and lignotubers) on land that was previously cleared and where regrowth has been suppressed for at least 10 years prior to commencement. To achieve this, the project's activities include the total exclusion of livestock in certain areas, the careful management of the timing and extent of allowable grazing, and the humane management of feral animals.

The Murchison area is historically known for its extensive pastoral leases, with the land predominantly utilised for sheep and cattle grazing. The environment features a semi-arid to arid climate classification with typically low and variable rainfall, whilst the region's soils are generally composed of red sandy earth and clay loams.

An interesting botanical note regarding the property is that the native plant species Eremophila ballythunnensis was named directly after Ballythunna Station, honoring the exact location where the plant was first observed. Additionally, on June 27, 2025, the project underwent a regulatory variation to update the primary proponent's name from Australian Integrated Carbon Financial Services Pty Ltd to Emissions Abatement Solutions (WA) Pty Ltd.
