'24 Degree Forest - Rainforest rehabilitation on slopes and riparian zones - Doon Doon

'24 Degree Forest - Rainforest rehabilitation on slopes and riparian zones - Doon Doon' is an environmental planting project located in Doon Doon, southwest of Murwillumbah and approximately 70km northwest of Byron Bay in the Northern Rivers region of NSW. It was registered in February 2026 and covers 72.12 hectares on a property that continues to host a productive Santa Gertrudis cattle breeding business.

Environmental planting projects involve establishing and maintaining permanent plantings of a mix of native tree species. Under the standard methodology requirements, these trees must be planted on land predominantly used for agricultural purposes for at least five years prior to project commencement, and established at a stocking density sufficient to achieve forest cover, typically meaning at least 200 stems per hectare.

The Doon Doon area is nestled within the Mount Warning (Wollumbin) Caldera and is heavily used for cattle farming, grazing, and general agriculture. The region is characterized by a high-rainfall, subtropical climate; a local rain gauge notably recorded a state record of 4,607mm of rain during the 2022 floods. The environment is predominantly defined by highly fertile, basalt-derived soils and alluvial clays, which are ideal for sustaining sub-tropical rainforests.

A notable fact about this project is its overlap with the federal government's Nature Repair Market (Project ID: NR001018, known as the Karinya Downs Wet Sclerophyll Forest and Rainforest Restoration). Registered in May 2026, it became Australia's second project to be registered under this scheme. This arrangement allows the proponent, 24 Degree Forest Pty Ltd, to pioneer "project stacking" on the same parcel of land, providing an educational model for local landholders to achieve both carbon and biodiversity certificate outcomes alongside ongoing agricultural operations.
