Seven Hills Environmental Planting Project

Seven Hills Environmental Planting Project is an environmental planting project located at Mullion Creek, approximately 20km north of Orange in the Cabonne local government area of New South Wales. It was registered in March 2024 and covers 58.76 hectares.

Environmental planting projects under the Reforestation by Environmental or Mallee Plantings methodology involve establishing permanent plantings of a mix of native or mallee species. Standard requirements generally involve planting native trees at a density of at least 200 stems per hectare, intended to eventually reach at least 2 meters in height and achieve a 20% canopy cover.

The region around Orange and the Central Tablelands is known for varied agricultural land use, prominently including sheep and cattle grazing, broadacre cropping, forestry, and horticulture. The area is considered a high, reliable rainfall region, and soils are generally fertile, encompassing basalt-derived and clay loam soil types.

This project establishes permanent mixed-species plantings using trees native to the local area, specifically targeting land that had been used predominantly for agriculture for at least five years prior to commencement. Interestingly, the project varied its method in May 2025 to align with the updated 2024 methodology, and later expanded its project area boundaries in July 2025. The proponent, Carbon Fix Pty Limited, also operates the closely associated "Seven Hills Soil Carbon Project", which covers over 1,000 hectares, indicating a broad, multi-method approach to carbon farming on the property.
