Mayfield Regeneration Project

Mayfield Regeneration Project is a Human-Induced Regeneration (HIR) project located at the Mayfield property, approximately 35km southwest of Charleville in outback Queensland. It was registered in August 2015 and covers 19,427.45ha.

Human-Induced Regeneration projects involve establishing permanent native forests through assisted regeneration from in-situ seed sources, including rootstock and lignotubers. Standard requirements to achieve this native forest cover involve significant changes to land management practices. For this project, activities include the cessation of mechanical or chemical destruction and suppression of regrowth, careful management of the timing and extent of livestock grazing, and managing feral animals in a humane manner.

The Charleville area serves as a major outback service center and is known as a hub for the cattle and sheep grazing industries. The region typically falls under a semi-arid climate classification with variable, low rainfall. Soils in this environment generally consist of red earths, sandy loams, and hard-setting clays typical of the Mulga Lands bioregion.

This project was specifically established on land that had been historically cleared of vegetation and where regrowth had been suppressed for at least 10 years prior to commencement. Originally registered by Jason and Benjamin Knight as the trustees for Knight Pastoral, a variation of proponent in December 2017 transferred the project to S & R McDonald Pty Ltd (acting as the Trustee for McDonald & Sons Family Trust). Supported by project agent Climate Friendly Pty Ltd, the project has been highly successful in generating carbon abatement; its Carbon Abatement Contract (CAC102213), first contracted in November 2015, was officially completed in July 2026.
