Darling River Eco Corridor 2

Darling River Eco Corridor 2 is a Human-Induced Regeneration (HIR) project located approximately 160km northwest of Bourke and 60km northeast of Wanaaring in the Far West region of New South Wales. Registered in June 2016, the project covers a substantial area of 24,637 hectares.

The project operates within the Mulga Lands bioregion, an area historically dominated by rangeland grazing of sheep, cattle, and goats. The environment is semi-arid, characterised by low and variable rainfall (averaging 250-300mm annually). The terrain typically consists of red earth and sandy loam soils, supporting vegetation communities such as Mulga (Acacia aneura) woodlands and Poplar Box systems, particularly near the Cuttaburra Creek and Paroo River catchments.

This project utilises the Human-Induced Regeneration (HIR) methodology. Unlike environmental planting, HIR does not involve planting seedlings. Instead, it requires landholders to implement management changes, specifically controlling the timing and extent of livestock grazing and managing feral animals (such as goats), to stop the suppression of native forest. This allows existing in-situ seed banks, rootstock, and lignotubers to regenerate into permanent native forest.

Terra Carbon Pty Ltd, the project proponent, is a wholly owned subsidiary of the GreenCollar Group, one of Australia's largest environmental markets investors. The "Darling River Eco Corridor" is part of a broader series of projects (including #3, #5, etc.) designed to create landscape-scale connectivity. The project has also been subject to external scrutiny, appearing in Freedom of Information proceedings involving the Australian Conservation Foundation, which highlights the high profile of large-scale HIR projects in this region.
