Darling River Eco Corridor 25

Darling River Eco Corridor 25 is a Human-Induced Regeneration (HIR) project located in the remote Mulga Lands bioregion of New South Wales, approximately 50 kilometers northeast of the small settlement of Wanaaring and roughly 180 kilometers northwest of the major regional hub, Bourke. Registered on November 20, 2017, the project encompasses a significant area of 26,293.42 hectares. The surrounding region is defined by vast, flat to slightly undulating rangelands used primarily for the extensive grazing of sheep, cattle, and goats.

This project operates under the Human-Induced Regeneration methodology, which involves changing land management practices to allow native forests to regenerate from natural seed sources, rootstock, or lignotubers. Unlike tree planting projects, HIR focuses on removing "suppressors" that prevent regrowth. For Darling River Eco Corridor 25, the primary activities include managing the timing and extent of livestock grazing and humanely controlling feral animals, particularly goats, which are a major cause of vegetation suppression in the area.

Environmentally, the site is situated in a semi-arid to arid zone with low and highly variable rainfall, averaging roughly 280mm annually. The soil landscape is characteristic of the Upper Darling and Paroo river catchments, consisting largely of red sandy loams and red earths (Kandosols) on the ridges and flats, with heavier clay soils (Vertosols) present in the low-lying claypans and floodplains. The project is part of a larger aggregation known as the "Darling River Eco Corridor," managed by Terra Carbon (a subsidiary of GreenCollar), which aims to create a contiguous zone of protected vegetation to improve biodiversity connectivity across the landscape.
