2021 AGECLASS - LIMESTONE PLANTATIONS

2021 AGECLASS - LIMESTONE PLANTATIONS is a plantation forestry project located in the Green Triangle region, approximately 70km north-west of Mount Gambier, crossing the South Australia and Victoria borders. It was registered in September 2020 and covers an area of 2,089.57 ha.

Plantation forestry projects involve generating carbon credits by establishing a new plantation forest, converting an existing short-rotation plantation to a long-rotation plantation, or maintaining a plantation that would otherwise be converted to non-forested land. Standard requirements include maintaining the plantation for the commercial harvesting of wood products, adhering to a silvicultural management plan, and achieving specific stocking densities to ensure adequate forest growth and long-term carbon sequestration.

The Green Triangle area is famous for its extensive commercial timber operations, as well as cattle grazing and agriculture. The region is considered a high rainfall environment with a Mediterranean climate, and the soils are generally sandy loams and terra rossa over limestone bedrock.

This project sequesters carbon by establishing a new plantation forest and converting an existing short-term rotation plantation into a long-term rotation plantation for commercial harvesting. In May 2021, the project underwent a variation to remove certain land areas from its boundary. Later, in May 2025, the proponent role was transferred from The Trust Company (PTAL) Limited to OneFortyOne Plantations Pty Ltd. Beyond traditional forestry, OneFortyOne is a major regional operator that actively invests in renewable energy initiatives, such as utilizing forestry waste and residue for biomass and renewable methanol production.
