Terraldon Regeneration Project

The Terraldon Regeneration Project is a Human-Induced Regeneration (HIR) project located on the historic Tinnenburra Station, approximately 100km south-west of Cunnamulla in South West Queensland. Registered in November 2018, the project encompasses a significant area of nearly 35,000 hectares. The property is situated within the Paroo Shire near the New South Wales border, an area geographically defined by the Warrego River and Cuttaburra Creek floodplains.

The region lies within the Mulga Lands bioregion, characterized by a semi-arid climate with highly variable rainfall and red earth or sandy loam soils. Historically, this area is synonymous with large-scale pastoralism; Tinnenburra itself was once one of Australia's most famous sheep stations, owned by the legendary "pastoral king" James Tyson in the late 19th century. Today, under the management of the Godfrey family, the land continues to be used for grazing sheep and cattle, integrating carbon farming into their agricultural operations to diversify income and improve land condition.

Human-Induced Regeneration (HIR) projects focus on restoring native forests on land where vegetation has been suppressed for at least 10 years, typically by livestock or feral animals. The Terraldon project utilizes the HIR 1.1 methodology, which requires landholders to undertake specific management activities to facilitate regrowth. In this instance, the proponents manage the timing and extent of grazing and control feral animals (such as goats and pigs) to allow native species, likely Mulga (Acacia aneura) and riverine eucalypts, to regenerate towards forest cover. The goal is to achieve a permanent native forest with a canopy cover of at least 20% and a height of 2 meters.
