Garrawilla

Garrawilla is a soil carbon project located at Garrawilla Station, a historic cattle property approximately 45km east of Coonabarabran in New South Wales. Registered in May 2022, the project covers a substantial area of 4,882 hectares within the North West Slopes region.

The project operates under the 2021 Soil Carbon "Measurement and Models" methodology. This framework requires land managers to estimate soil organic carbon stocks through baseline sampling and then implement new management activities designed to sequester carbon. For Garrawilla, these activities include altering grazing intensity to promote vegetation cover, applying nutrients (synthetic or non-synthetic fertilizers) to address deficiencies, using lime or gypsum to manage soil acidity or sodicity, and rejuvenating pastures through seeding.

The Garrawilla property itself is situated in a region known for its unique geology, specifically the "Garrawilla Volcanics," which formed around 20 million years ago. Consequently, the area is characterized by volcanic landscapes and basalt-derived soils, which are generally fertile but can vary in depth and rockiness. The region typically experiences a temperate climate with an average annual rainfall of approximately 670mm. Garrawilla Station is historically significant, established in the 1840s and often cited as one of the first properties settled in the district, with a history linking back to the era of explorer John Oxley.
