Catchment Conservation Alliance - Great Barrier Reef Initiative Site #19

Catchment Conservation Alliance - Great Barrier Reef Initiative Site #19 is a Human-Induced Regeneration project located in the Central Highlands region of Queensland, approximately 40km west of Emerald. It was registered in February 2022 and covers 4,318.51ha.

Human-Induced Regeneration projects involve regenerating native forests by changing land management practices, allowing previously cleared or degraded land to naturally regrow. This methodology requires proponents to conduct specific activities such as ceasing the mechanical or chemical destruction of regrowth and carefully managing the timing and extent of livestock grazing. These interventions ensure that vegetation can reach forest cover by regenerating from in-situ seed sources, such as existing rootstock and lignotubers.

The Central Highlands area is well known for extensive cattle grazing and both dryland and irrigated cropping operations. The region experiences a hot, semi-arid climate with distinct summer-dominant rainfall, and the regional soils are typically characterised by fertile cracking clays (vertisols), alluvial soils, and sandy loams.

This project was established on land that had been extensively cleared of vegetation and where forest regrowth was actively suppressed for at least 10 years prior to the project's commencement. In February 2026, a variation to the project area successfully removed certain parcels of land from the registered boundaries. The project's proponent, Terra Carbon Pty Limited, operates as a holding entity for GreenCollar, which is Australia’s largest environmental markets developer. GreenCollar manages a massive and diverse portfolio extending over 5 million hectares across more than 200 project locations in Australia.
