Darling River Eco Corridor #37

Darling River Eco Corridor #37 is a Human-Induced Regeneration (HIR) project located approximately 110km west of Cobar and southeast of the remote locality of Tilpa in Western New South Wales. Registered in May 2018, the project originally encompassed an area of 13,512 hectares, though a variation in January 2021 involved the removal of certain areas from the project boundary. The project is situated within the Barnato Downs bioregion, an area traditionally utilized for extensive grazing of sheep, cattle, and goats.

The project operates under the Human-Induced Regeneration methodology, which involves changing land management practices to allow the regeneration of native forests from in-situ seed sources, rootstock, or lignotubers. Unlike environmental planting, this method focuses on removing suppression agents, specifically by managing the timing and extent of livestock grazing and humanely controlling feral animals (particularly goats) that otherwise consume young vegetation. The goal is to facilitate the return of a permanent, even-aged native forest cover.

Environmentally, the region is classified as semi-arid with variable, often low rainfall. The landscape consists of flat to undulating terrain featuring red earth soils typical of the Cobar Peneplain. The vegetation regenerating in this corridor includes species such as Mulga (Acacia aneura), White Cypress Pine (Callitris glaucophylla), Bimble Box (Eucalyptus populnea), and Turpentine (Eremophila sturtii). By reducing grazing pressure, these native species are able to re-establish, stabilizing soils and creating habitat for local biodiversity.

The project is part of a broader initiative by the proponent, Terra Carbon Pty Ltd (a subsidiary of GreenCollar), known as the "Darling River Eco Corridor." This initiative aggregates multiple properties across the upper catchments of the Darling River to create large-scale landscape connectivity. The project generates Australian Carbon Credit Units (ACCUs) by sequestering carbon in the biomass of the regenerating forest over a permanent period of 100 years.
