Darling River Eco Corridor #33

Darling River Eco Corridor #33 is a Human-Induced Regeneration (HIR) project located in the remote rangelands of northern New South Wales, approximately 40 kilometers northeast of the town of Bourke. Registered in November 2017, the project covers a significant area of 36,137 hectares within the Bourke Shire Council local government area.

The project sits within the Mulga Lands bioregion, an area historically dominated by rangeland grazing for sheep, cattle, and goats. The environment is semi-arid to arid, typically receiving low and variable rainfall (roughly 250-300mm annually). The landscape is characterized by red sandy loam soils (kandosols) supporting Mulga (Acacia aneura) and Poplar Box woodlands, interspersed with clay-rich floodplains (vertosols) near watercourses.

Operating under the Human-Induced Regeneration methodology, this project does not involve planting new trees. Instead, it regenerates permanent native forests from in-situ seed sources, lignotubers, and rootstock by removing suppression activities. The primary activities involved are the management of livestock grazing pressure, often through fencing and rotational grazing, and the humane control of feral animals, particularly goats, which are a major suppressor of vegetation growth in the region.

This project is part of a larger aggregation known as the "Darling River Eco Corridor," developed by GreenCollar (via its subsidiary Terra Carbon). This initiative aims to create a contiguous zone of protected vegetation along the upper catchments of the Darling River system, providing landscape-scale biodiversity benefits and soil stabilization alongside carbon sequestration.
