Maranalgo Station Regeneration Project

The Maranalgo Station Regeneration Project is a Human-Induced Regeneration (HIR) project located on Maranalgo Station, a remote pastoral property in the Shire of Yalgoo, Western Australia. The project area sits approximately 70 kilometers northeast of Paynes Find and about 145 kilometers southeast of Mount Magnet. Registered in October 2018, the project originally covered a vast expanse of over 68,000 hectares within the station's boundaries. The region is characterized by its use for rangeland grazing, primarily for cattle and sheep, which has historically been the dominant economic activity in this part of the Mid West.

HIR projects like this one are designed to restore native forest cover by addressing the specific suppressors that prevent regeneration, in this case, grazing pressure. By actively managing the timing and extent of grazing by livestock and feral animals (such as goats), the project allows existing rootstock and lignotubers to mature into permanent even-aged native forests. This method does not involve planting new trees but rather relies on the resilience of the local seed bank to recover once the suppression is removed.

Environmentally, the Maranalgo area lies within the arid to semi-arid rangelands, featuring a landscape of red earth, shallow sandy loams, and significant lake systems. The vegetation is typical of the Murchison bioregion, dominated by Mulga (Acacia aneura) woodlands and saltbush country. Rainfall is low and highly variable, generally averaging between 200mm and 250mm annually, which dictates the slow but steady pace of regeneration.

The project has seen significant administrative changes following the sale of the station in late 2022. Originally held by an individual proponent, the project responsibility was transferred in September 2024 to Augie Grandall Pty Ltd as Trustee for The Maranalgo Property Trust. Recent variations in 2025 have adjusted the project area, removing specific parcels of land, which is a common practice in large-scale carbon projects to account for infrastructure, mining tenements, or areas where regeneration performance may not meet audit requirements.
