Mullagalah II Regeneration Project

Mullagalah II Regeneration Project (ERF109630) is a Human-Induced Regeneration project located approximately 45km south-east of Bourke in the outback region of New South Wales. It was registered on March 23, 2017, and covers an area of 5,253.08 hectares.

Human-Induced Regeneration (HIR) projects involve establishing permanent, even-aged native forests by permanently stopping activities that previously suppressed tree growth. The standard requirements dictate that landholders manage or remove these suppressors to allow natural, in-situ vegetation to regenerate and reach a forest cover threshold, defined as a minimum of 20% crown cover and trees at least 2 metres tall.

The Bourke area is well known as a service centre for the surrounding pastoral district, with broadacre sheep and cattle grazing being the dominant land use. The region experiences a semi-arid outback climate with low and highly variable rainfall, averaging around 331mm annually. Soils in this region generally consist of red duplex soils (Chromosols), earthy red soils (Kandosols), and sandy loams.

This project aims to establish permanent native forests through assisted regeneration from in-situ seed sources, such as rootstock and lignotubers. It specifically targets land that was previously cleared of vegetation and where natural regrowth had been suppressed for at least 10 years prior to commencement. To achieve this regeneration, the proponents are actively managing the timing and extent of livestock grazing and undertaking the humane management of feral animals.

Historically, the project was managed by Michael and Tanya Marshman. In August 2020, Kurrajong Partners Pty Ltd was added as a proponent. Shortly after this, the project successfully secured a fixed delivery Carbon Abatement Contract (CAC787990) with the Commonwealth in October 2020 for 92,045 tonnes of abatement, which has since been fully completed. In August 2025, Kurrajong Partners was removed from the registry, and the proponent varied back to solely Michael and Tanya Marshman.
