Inverness Human-Induced Regeneration Project

Inverness Human-Induced Regeneration Project is a large-scale regeneration project located approximately 70km northwest of Brewarrina in Northern New South Wales. Registered in July 2015, the project spans a significant area of 18,785 hectares. The property is situated within the Mulga Lands bioregion, an area historically dominated by rangeland grazing for sheep and cattle, which remains the primary land use in the surrounding district.

The project operates under the Human-Induced Regeneration (HIR) methodology. This specific carbon farming method involves altering land management practices, primarily by managing the timing and extent of livestock grazing and controlling feral animals, to cease the suppression of native regrowth. The objective is to allow existing native vegetation to regenerate into a permanent even-aged forest, which is legally defined as achieving a canopy cover of at least 20% and a height of 2 meters.

Environmentally, the region experiences a semi-arid climate with highly variable rainfall, averaging between 300mm and 350mm annually. The landscape is characterized by red earth soils and sandy loams, which typically support vegetation communities dominated by Mulga (Acacia aneura) and bimble box woodlands. These soil types are often low in fertility, making the preservation of native vegetation cover crucial for preventing erosion.

Terra Carbon Pty Limited is listed as the project proponent. It is notable that Terra Carbon is a subsidiary of the GreenCollar Group, one of Australia's largest environmental market investors and project developers. The project does not involve planting new trees; instead, it relies on "assisted regeneration" from in-situ seed sources, rootstock, and lignotubers that were previously suppressed by agricultural activity.
