2020 AGE CLASS, LIMESTONE PLANTATIONS

2020 AGE CLASS, LIMESTONE PLANTATIONS is a Plantation Forestry project located in the Limestone Coast region of South Australia, approximately 75km north-west of Mount Gambier. It was registered in March 2020 and covers 281.41 hectares.

Plantation forestry projects generate carbon abatement by establishing new plantations, converting short-rotation plantations to long-rotation ones, or changing existing management practices to increase carbon storage. This specific project generates Australian Carbon Credit Units (ACCUs) by converting an existing short-rotation plantation forest into a long-rotation plantation forest designed for the commercial harvesting of wood products. By extending the rotation length rather than harvesting early for pulpwood, the trees grow larger and are ultimately harvested for long-lived commercial wood products like sawlogs, keeping the sequestered carbon locked away for significantly longer periods.

The Limestone Coast and the broader Green Triangle area are renowned for extensive commercial softwood and hardwood forestry operations, which operate alongside broadacre cropping and livestock grazing. The region features a Mediterranean climate and is considered a moderate to high rainfall area for South Australia, generally averaging between 600mm and 850mm annually. The local landscape contains variable soil types, prominently including shallow loamy sand over limestone or calcrete, as well as highly fertile volcanic ash soils closer to the dormant volcanoes of Mount Gambier.

Over its lifetime, the project has undergone multiple administrative updates. In May 2021, a variation was applied to remove certain areas from the initial project boundary. Later, in May 2025, the principal participant name was officially transferred from The Trust Company (PTAL) Limited (as trustee for ANZFOF2 Sub 1) to the current proponent, ONEFORTYONE PLANTATIONS PTY LTD. OneFortyOne is a major trans-Tasman sustainable forest grower that manages extensive plantation assets and timber processing operations across the Green Triangle region.
