2020 AGE CLASS, LIMESTONE PLANTATIONS

2020 AGE CLASS, LIMESTONE PLANTATIONS is a plantation forestry project located approximately 28km southwest of Naracoorte in the Green Triangle region of South Australia. It was registered in March 2020 and covers 281.41ha.

Plantation forestry projects generate carbon credits by establishing new plantations, transitioning from a short-rotation to a long-rotation, or changing from pulpwood to sawlog production. The standard methodology requires the forest to be managed for commercial harvesting while ensuring long-term carbon storage in both the standing forest biomass and the resulting wood products.

The Naracoorte and broader Green Triangle region is renowned as Australia's most intensive timber plantation area, dominated by softwood (radiata pine) and hardwood (blue gum) forestry, alongside agricultural grazing and cropping. The area experiences a temperate climate with reliable, effective winter rainfall and low evaporation. Soils in the region generally comprise sandy loams overlying karstic limestone and clay.

This project sequesters carbon by converting an existing short-rotation plantation forest to a long-rotation plantation for commercial harvesting. By keeping the trees in the ground longer, the forest stores significantly more carbon before yielding higher-value structural wood products. The project area underwent a variation in May 2021 to remove certain land parcels, and in May 2025, the primary participant name was officially updated to OneFortyOne Plantations Pty Ltd. This ACCU project aligns closely with OneFortyOne's broader corporate sustainability initiatives, which include a major commitment to reducing their scope 1 and 2 greenhouse gas emissions by 75% by 2030.
