Biodiverse Carbon Conservation Arthursleigh (Revoked)

Biodiverse Carbon Conservation Arthursleigh (Revoked) is an environmental planting project located on the "Arthursleigh" property, approximately 12 kilometers northeast of Marulan in the New South Wales Southern Tablelands. The project was registered in July 2015 and covered a significant area of 6,358 hectares. However, it was revoked under section 33 of the Carbon Credits (Carbon Farming Initiative) Act 2011 on August 28, 2017, meaning it is no longer an active carbon project.

The project operated under the 2012 "Carbon Farming (Quantifying Carbon Sequestration by Permanent Environmental Plantings of Native Tree Species using the CFI Reforestation Modelling Tool)" methodology. This method requires establishing permanent plantings of native tree species on land that has been cleared of forest for at least five years. The goal is to sequester carbon in the growing biomass of these trees, typically planted at a density sufficient to form a forest canopy (often at least 200 stems per hectare).

The Arthursleigh property itself is a commercial farm owned by the University of Sydney, which uses the land for teaching and research in pasture agronomy and animal science. The region is characterized by a temperate climate with moderate rainfall. The landscape typically features texture-contrast soils such as Chromosols and Kurosols, which can be acidic and are common in the Southern Tablelands. The land use in the surrounding Marulan and Goulburn area is predominantly grazing (sheep and cattle) and cereal cropping.

An interesting development for this location is the subsequent proposal for the "Wattle Creek Energy Hub" on the same property. In recent years, the University of Sydney partnered with Spark Renewables to investigate a hybrid renewable energy facility (solar and battery storage) at Arthursleigh, highlighting the site's evolving role in sustainable resource management beyond the original scope of the revoked carbon project.
