Darling River Eco Corridor #37

Darling River Eco Corridor #37 is a Human-Induced Regeneration (HIR) project located approximately 110km west-southwest of Cobar and south-east of Tilpa in the Western Division of New South Wales. Registered on May 24, 2018, the project covers a substantial area of 13,512 hectares within the Barnato Downs bioregion. This region is characterized by semi-arid rangelands traditionally used for grazing sheep, cattle, and goats.

Human-Induced Regeneration projects involve the cessation of activities that suppress vegetation, allowing native forests to regenerate naturally from in-situ seed sources, rootstock, or lignotubers. For this specific project, the primary activity is the management of grazing pressure, likely through the control of feral goats and the strategic management of livestock timing and extent, along with the upgrading of fencing and water infrastructure. The goal is to allow the suppressed vegetation to reach "forest cover" status (20% canopy cover and 2 meters in height) to generate Australian Carbon Credit Units (ACCUs).

The environment in this part of the Cobar Peneplain typically experiences low, variable rainfall (averaging 300-350mm annually) and features red earth soils, clay loams, and lithosols on ridges. The native vegetation regenerating in this corridor includes species such as White Cypress Pine (Callitris glaucophylla), Mulga (Acacia aneura), Bimble Box (Eucalyptus populnea), and various Eremophila species.

It is worth noting that the proponent, Terra Carbon Pty Limited, is a subsidiary of the GreenCollar Group, Australia's largest environmental markets investor. The project is part of a broader "Darling River Eco Corridor" initiative, suggesting a landscape-scale approach to connectivity and conservation. As indicated in the project notes, the registered area was varied in January 2021, which often reflects the refinement of Carbon Estimation Areas (CEAs) where regeneration is most viable.
