Western Australia Rangelands Conservation Initiative Site 18

Western Australia Rangelands Conservation Initiative Site 18 is a Human-Induced Regeneration (HIR) project located near the Billabong Roadhouse and Nerren Nerren in the Mid West region of Western Australia, approximately 244km north of Geraldton. It was registered in March 2021 and originally covered a massive 154,414.99 hectares.

Human-Induced Regeneration projects involve establishing permanent native forests on land where vegetation was previously cleared and regrowth has been suppressed for at least 10 years. Under this methodology, landholders earn carbon credits by stopping those suppressive activities to allow native trees to regenerate from in-situ seed sources, such as rootstock and lignotubers. Standard requirements include active land management; for this specific project, this involves managing the timing and extent of livestock grazing, as well as the humane management of feral animals.

The surrounding Mid West and Gascoyne rangelands region is traditionally known for extensive pastoral operations, primarily broadacre sheep and cattle grazing. The environment is semi-arid and experiences low rainfall, while local soils generally consist of red-brown sandy loams, skeletal soils, and clay plains.

The project is managed by the proponent Terra Carbon Pty Limited and forms part of a broader network of regeneration sites under the Western Australia Rangelands Conservation Initiative. As the project has evolved over its crediting period, the total property boundaries have undergone variations, with the area amended in September 2023 and portions of the listed area subsequently removed in July 2026.
