Tiltagara Human Induced Regeneration Project

Tiltagara Human Induced Regeneration Project is a Human-Induced Regeneration (HIR) project located approximately 95km south-west of Cobar in the Upper Western region of New South Wales. It was registered in September 2023 and covers an extensive area of 14,230.44 hectares.

Human-Induced Regeneration projects involve establishing permanent native forests through assisted regeneration from in-situ seed sources, such as rootstock and lignotubers. To meet the standard requirements of the methodology, the project area must be on land that was previously cleared of native vegetation and where regrowth was actively suppressed for at least 10 years prior to the project commencing. Project activities primarily involve managing the timing and extent of livestock grazing and humanely controlling feral animals. Removing these grazing pressures allows the native vegetation to naturally regenerate and eventually reach a forest canopy cover.

The Cobar region is historically known for its large pastoral holdings, predominantly used for sheep and cattle grazing operations. The environment is classified as semi-arid, experiencing highly variable and sometimes extreme rainfall with an annual average of around 390mm to 400mm. The soils in this pastoral region are predominantly red Chromosols and Vertosols (cracking clays), with some areas naturally hardsetting or degraded after years of continuous agricultural use.

The project proponent, Terra Carbon Pty Limited, is a subsidiary entity of GreenCollar, which operates as Australia's largest environmental markets investor and project developer. In a recent public registry update from August 2026, it was noted that 377 Australian Carbon Credit Units (ACCUs) associated with the Tiltagara Human Induced Regeneration Project had been relinquished.
