Darling River Eco Corridor #39

Darling River Eco Corridor #39 is a Human-Induced Regeneration (HIR) project located in the remote Unincorporated Far West region of New South Wales, approximately 85km northwest of the opal-mining town of White Cliffs. Registered in May 2018, this large-scale project covers 23,556 hectares of rangeland situated within the semi-arid Mulga Lands bioregion.

Human-Induced Regeneration projects in this context do not involve planting trees; rather, they focus on managing the land to allow existing native seed banks and suppressed rootstock to regenerate naturally. The primary activities for this project involve controlling the timing and extent of grazing by livestock (sheep and cattle) and actively managing feral animals, particularly goats, which are a major suppressor of vegetation in the area. By reducing this grazing pressure, native forests are able to reach forest cover maturity (2m height and 20% canopy density).

The project area is characterized by a semi-arid climate with low, variable rainfall (averaging roughly 250mm annually) and hot summers. The terrain typically consists of red sandy loams and red earths, supporting vegetation such as Mulga (Acacia aneura), Poplar Box (Eucalyptus populnea), and various Eremophila species. As part of the broader "Darling River Eco Corridor" portfolio managed by Terra Carbon (a GreenCollar subsidiary), this project contributes to a landscape-scale effort to improve connectivity and biodiversity across over 150,000 hectares of the Darling River catchment while diversifying income for local graziers.
