Wiralla Regeneration Project

The Wiralla Regeneration Project (ERF116713) is a Human-Induced Regeneration (HIR) project located on Wiralla Station, approximately 60km northeast of the township of Thargomindah in South West Queensland. Registered in March 2018, the project encompasses a significant area of 51,107 hectares. The property sits within the Bulloo Shire and the wider Mulga Lands bioregion, an area traditionally dominated by rangeland grazing for cattle and sheep.

Human-Induced Regeneration projects in this context focus on restoring native forest cover through the cessation of suppression activities. Instead of active tree planting, the project facilitates regeneration from in-situ seed sources (such as rootstock and lignotubers) by managing the timing and extent of grazing and stopping mechanical or chemical clearing. For Wiralla, this involves managing cattle stocking densities to allow suppressed vegetation, specifically Mulga (Acacia aneura) and associated species, to reach forest maturity.

The environment in this region is characterized by a semi-arid climate with highly variable, summer-dominant rainfall, averaging approximately 280mm per year. The terrain typically consists of flat to undulating plains with red earth and sandy loam soils, which are well-suited to the hardy Mulga woodlands that define the landscape. These soils are generally low in fertility, making the native vegetation critical for preventing erosion and maintaining soil health in such a dry climate.

The project is operated by Amaral Pastoral Pty Limited, working with service provider Climate Friendly Pty Ltd. Amaral Pastoral manages other carbon projects in the region, including the nearby Jandell Regeneration Project. Notably, Australian Carbon Credit Units (ACCUs) from the Wiralla project have been purchased by major corporate buyers, such as Lion (the beverage company), to offset emissions under the Climate Active program. The property itself, Wiralla Station, is an active cattle station, demonstrating the integration of carbon farming with traditional agricultural operations.
