Mullagalah II Regeneration Project

Mullagalah II Regeneration Project is a Human-Induced Regeneration (HIR) project located approximately 45km southeast of Bourke in New South Wales. It was registered in March 2017 and covers 5,253ha.

Human-Induced Regeneration projects involve establishing permanent native forests through assisted regeneration from in-situ seed sources, such as rootstock and lignotubers. This methodology is applied to land that was previously cleared of vegetation and where regrowth was actively suppressed for at least 10 years prior to the project commencing. To achieve forest regeneration, the project activities include managing the timing and extent of livestock grazing, alongside managing feral animals in a humane manner.

The Bourke area is a quintessential outback region known primarily for broadscale sheep, goat, and cattle grazing, as well as irrigated cotton farming where water from the Darling River is available. The region experiences a hot, semi-arid climate with low average annual rainfall of approximately 370mm. Soils in the district generally consist of red and sandy loams with stony ridges, transitioning to heavier alluvial clay soils (Vertosols) on the river floodplains.

This project successfully completed a carbon abatement contract (CAC787990) with the Australian Government in October 2020, fulfilling a fixed delivery obligation of 92,045 Australian Carbon Credit Units (ACCUs). The proponents, Michael and Tanya Marshman, are also participants in a contiguous or related carbon project named the "Mullagalah Regeneration Project" (EOP101098), an even larger HIR project covering over 11,000 hectares.
