Darling River Eco Corridor 25

Darling River Eco Corridor 25 is a Human-Induced Regeneration (HIR) project located in the remote Mulga Lands of New South Wales, approximately 140km northwest of Bourke and east of the small outback settlement of Wanaaring. Registered in November 2017, the project encompasses a significant area of approximately 26,293 hectares.

The region consists of semi-arid rangelands primarily used for extensive grazing of sheep, cattle, and goats. The environment is characterized by low rainfall and red sandy loam soils, often featuring stony ridges and clay pans typical of the Upper Darling catchment. Vegetation in this area is dominated by hardy native species such as Mulga (Acacia aneura), Turpentine (Eremophila sturtii), and Bimble Box (Eucalyptus populnea).

This project operates under the Human-Induced Regeneration methodology, which differs from tree planting. Instead, it involves changing land management practices, specifically managing the timing and extent of grazing and controlling feral animals like goats, to allow suppressed native forests to regenerate naturally from existing seed banks and rootstock.

Developed by Terra Carbon (a subsidiary of GreenCollar), this project is part of the broader "Darling River Eco Corridor" initiative, which aggregates over 150,000 hectares of land. These projects are designed to provide drought-resilient income streams for graziers, funding infrastructure upgrades such as fencing and trap yards that improve both farm productivity and environmental health.
