Rossmore Landscape Project

Rossmore Landscape Project is a soil carbon project located approximately 8km northeast of Burren Junction, and roughly 40km west of Wee Waa in the Walgett Local Government Area of northwestern New South Wales. It was registered in October 2021 and covers a substantial area of 6618.30 hectares.

Soil carbon projects under the Estimation of Soil Organic Carbon Sequestration using Measurement and Models methodology involve changing agricultural management practices to increase the storage of carbon in the soil. These methods require a combination of direct soil sampling and computer modelling to calculate carbon sequestration over time. In this specific project, the proponents are altering the stocking rate, duration, and intensity of their livestock grazing to promote soil vegetation cover and improve soil health. They are also applying synthetic or non-synthetic fertilisers to address material nutrient deficiencies in the land.

The Lower Namoi Valley region around Burren Junction and Wee Waa is a prominent agricultural area known heavily for cotton, wheat, and cattle farming. The climate is semi-arid, experiencing an average annual rainfall of approximately 580mm. The soils in this region are predominantly heavy black and brown cracking clays (vertosols) alongside some alluvial loams, which provide fertile grounds for broadacre cropping and grazing enterprises.

Rossmore Agriculture Pty Ltd acts as the project proponent as trustee for the Sendall Family Trust, with Climate Friendly Pty Ltd assisting as the project agent. In February 2026, the project underwent a methodology variation, transitioning from the older 2018 soil carbon measurement methodology to the updated 2021 measurement and models determination. The project has elected a 25-year permanence period.
