Darling River Eco Corridor 5

Darling River Eco Corridor 5 is a Human-Induced Regeneration (HIR) project located in the Mulga Lands bioregion of New South Wales, approximately 125km northwest of Bourke and east of Wanaaring. Registered in June 2016, the project covers a substantial area of 24,725 hectares within the remote "Back O' Bourke" region. The surrounding landscape is primarily dedicated to extensive rangeland grazing, utilizing the native vegetation to support sheep, cattle, and harvested feral goats.

This project operates under the Human-Induced Regeneration methodology, which involves restoring native forest cover on land where vegetation regrowth has been suppressed for at least 10 years, typically by overgrazing. To achieve this, the project activities include managing the timing and extent of livestock grazing and implementing humane control measures for feral animals, particularly goats which are prevalent in the area. These interventions allow existing seed stocks and root systems to regenerate into permanent, even-aged native forests.

The environmental setting is classified as semi-arid to arid, characterized by low and variable rainfall (averaging roughly 300mm annually). The terrain features undulating sandy country with red earth soils (Kandasols) and claypans. Vegetation in this specific corridor is dominated by Mulga (Acacia aneura) stands, interspersed with native grasses, shrubs such as Eremophila, and heavier timber like Poplar Box and Coolabah near the ephemeral creek systems and swamps that traverse the southern sections of the property.

An interesting facet of this project is its inclusion in a broader aggregation of "Darling River Eco Corridor" projects managed by GreenCollar (via the proponent Terra Carbon Pty Limited). This series of projects aims to create a contiguous zone of conservation and carbon sequestration across the region's fragile rangelands. The project holds a carbon abatement contract with the Australian Government, securing the sale of a portion of its generated Australian Carbon Credit Units (ACCUs).
