Western Australia Rangelands Conservation Initiative Site 18

Western Australia Rangelands Conservation Initiative Site 18 is a Human-Induced Regeneration project located in the Mid West rangelands of Western Australia, approximately 10km southwest of the Billabong Roadhouse and 150km north-northeast of Kalbarri. It was registered in March 2021 and covers an extensive area of 154,425.85ha.

Human-Induced Regeneration projects involve establishing permanent even-aged native forests through assisted regeneration from in-situ seed sources, such as rootstock and lignotubers. A standard requirement of this methodology is that it must occur on land where vegetation was cleared and regrowth was suppressed for at least 10 years prior to the project commencing. To achieve this, project activities involve carefully managing the timing and extent of livestock grazing, as well as humanely managing feral animal populations to relieve pressure on native flora.

The Mid West rangelands region is traditionally known for large-scale pastoral leases that operate sheep and cattle grazing stations. The environment is considered arid to semi-arid, experiencing low and highly variable rainfall that averages between 200mm and 250mm annually. Soils in this region are generally characterized by red sandy earths, shallow loams, and extensive red-brown hardpan plains.

The proponent of this project, Terra Carbon Pty Limited, is a subsidiary of the GreenCollar Group, which is one of Australia's largest environmental market project developers. This project forms part of a much larger network of conservation sites under the "Western Australia Rangelands Conservation Initiative" managed by the group. Additionally, a variation was recorded in September 2023 to amend the areas listed in the project, which is a routine administrative process to refine carbon estimation areas and ensure strict compliance with the methodology.
