South Tambo (Revoked)

South Tambo (Revoked) was a soil carbon sequestration project located approximately 20 kilometers south of Tambo in Central West Queensland. Registered in August 2015 by Country Carbon Pty. Ltd., the project covered a substantial area of nearly 45,000 hectares. The project operated for less than two years before being voluntarily revoked in March 2017 under section 33 of the Carbon Farming Initiative Act 2011, which typically indicates a strategic decision by the proponent to withdraw rather than a compliance failure.

The project operated under the Sequestering Carbon in Soils in Grazing Systems methodology. This method awards carbon credits to landholders who implement new management activities, such as altering stocking density, installing new fencing for rotational grazing, or pasture rejuvenation, to increase the amount of organic carbon stored in the soil. The specific activities for South Tambo involved rejuvenating pastures and adjusting grazing patterns to improve soil health and carbon retention.

The Tambo region is characterized by a semi-arid climate with a mean annual rainfall of approximately 530mm. The landscape in this area, particularly south of the township, is often defined by open Mitchell grass downs featuring cracking clay soils (Vertosols), which are naturally fertile but reliant on variable rainfall. These heavy clay soils are well-suited to the soil carbon methodology, as they have a high capacity to hold water and organic matter when managed effectively.
