Ballythunna Station, Murchison HIR Aggregation

Ballythunna Station, Murchison HIR Aggregation is a Human-Induced Regeneration (HIR) project located in the semi-arid upper Murchison region of Western Australia, situated inland from the coastal town of Carnarvon along the Mullewa–Carnarvon Road. Registered in August 2020, the project covers a vast area of 124,833.49 hectares. The regional land use is dominated by remote pastoral leases, primarily focused on extensive sheep and cattle grazing. Environmental conditions reflect the classic Western Australian rangelands, featuring a low-rainfall, semi-arid climate. The soils in this specific area are typically shallow, brown, loamy clays positioned along the slopes of rocky quartzite rises.

Human-Induced Regeneration projects aim to establish permanent even-aged native forests on land where natural vegetation regrowth has been suppressed for at least 10 years prior to the project's commencement. Standard requirements dictate that landholders manage suppressors, such as livestock or feral animals, so the land can naturally regenerate from in-situ seed sources, including resilient rootstocks and lignotubers. Successful HIR projects eventually form a native forest canopy that reaches above 2 metres in height with at least 20% crown cover. To achieve this, the primary project activities at Ballythunna Station include the strategic exclusion and timing management of livestock grazing, alongside the humane management of feral animals.

An interesting ecological note about this property is that a rare native shrub species, Eremophila ballythunnensis, was named directly after Ballythunna Station, which is where the species was first discovered naturally growing in the property's loamy clay soils. Administratively, the project underwent a participant name variation on June 27, 2025, successfully transitioning from Australian Integrated Carbon Financial Services Pty Ltd to Emissions Abatement Solutions (WA) Pty Ltd.
