Yallalong Station Murchison HIR Aggregation

Yallalong Station Murchison HIR Aggregation is a Human-Induced Regeneration project located at Yallalong Station in the Murchison region of Western Australia, approximately 170km north-northeast of Geraldton. It was registered in August 2020 and covers a vast area of 271,663.32 hectares.

Human-Induced Regeneration projects involve establishing permanent, even-aged native forests by changing land management practices to allow native trees to naturally regenerate. For this project, standard activities include the exclusion of livestock, the humane management of feral animals, and carefully controlling the timing and extent of grazing. These practices enable the assisted regeneration of native vegetation from in-situ seed sources, such as rootstock and lignotubers, on land that was previously cleared and where regrowth had been suppressed for at least 10 years.

The broader Murchison region is predominantly used for large-scale pastoral leases focused on grazing sheep and cattle. The environment is characterised by a semi-arid to subtropical desert climate with highly erratic, low annual rainfall averaging around 230-250mm. The soils across this landscape generally consist of red shallow loams, red earths over hardpan, and sandy colluvium flats, which support the region's typical mulga and acacia shrublands.

An interesting note about this project is that in July 2024, a variation was made to the project area, removing certain listed areas from the overall boundary. Furthermore, the proponent, Australian Integrated Carbon Financial Services Pty Ltd, secured an optional delivery carbon abatement contract with the Clean Energy Regulator, initially committing to deliver over 384,000 Australian Carbon Credit Units (ACCUs) from this aggregation.
