2023 Age Class - Limestone Plantations

2023 Age Class - Limestone Plantations is a plantation forestry project located at a site approximately 30km northwest of Penola in the Naracoorte Lucindale area of South Australia's Green Triangle region. It was registered in June 2023 and covers an area of 396.66 hectares.

Plantation forestry projects involve establishing new plantations, transitioning from short-rotation to long-rotation harvesting cycles, or converting to permanent forests for commercial wood products. The methodology requires projects to sequester carbon in the growing trees while carefully managing commercial harvest cycles over the permanence period, which for this specific project is nominated as 25 years.

The Green Triangle region is well-known as Australia's largest plantation forestry hub, alongside mixed farming, cropping, and livestock grazing. The area benefits from a reliable, winter-dominated high rainfall climate. The local soils generally consist of neutral pH grey and brown sands on the flats, with alkaline red loams sitting atop the region's characteristic limestone outcrops.

This project sequesters carbon by both establishing new plantation forests and converting existing short-rotation plantations to long-rotation forests. Originally held by The Trust Company (PTAL) Limited, the proponent was officially changed to OneFortyOne Plantations Pty Ltd in May 2025. This variation followed OneFortyOne's major acquisition of the Limestone Coast estate, with the transition from short-rotation hardwood to long-rotation softwood acting as a strategic move to boost the region's domestic sawlog supply for future decades. Agent SFM Environmental Solutions continues to assist with the carbon management of the estate.
