Wambin Carbon Project

The Wambin Carbon Project is a Human-Induced Regeneration (HIR) project located approximately 70 kilometers south-south-west of Quilpie in South West Queensland. Registered in September 2015, the project covers a significant landholding of 65,392 hectares. The property sits within the Mulga Lands bioregion, an area historically utilized for extensive sheep and cattle grazing, often on the fringe of the Channel Country.

Human-Induced Regeneration projects in this context involve altering land management practices to allow native forests to regenerate from in-situ seed sources, such as rootstock and lignotubers. For the Wambin Carbon Project, this specifically entails managing the timing and extent of grazing pressure and controlling feral animals. These activities are designed to suppress mechanical clearing and reduce browsing pressure, thereby enabling the suppressed "Mulga" (Acacia aneura) and other native vegetation to return to a permanent forest cover.

The environmental setting for the project is classified as semi-arid, characterized by low and highly variable rainfall, typically averaging between 300mm and 400mm annually. The terrain is dominated by red earth soils and stony ridges typical of the soft and hard Mulga country found in the Quilpie Shire. The project is managed by Bignell Pty. Ltd. in partnership with carbon service provider Climate Friendly, demonstrating how long-term pastoral families in the region are diversifying operations by integrating carbon farming with traditional grazing.
