Landscape Aggregation

Landscape Aggregation is a Human-Induced Regeneration (HIR) project located approximately 90km south-west of Cunnamulla in the Paroo local government area of South West Queensland. It was registered in April 2016 and covers an area of 19,367.85 hectares.

Human-Induced Regeneration projects aim to establish permanent, even-aged native forests through assisted regeneration from in-situ seed sources, including rootstock and lignotubers. A standard requirement for this methodology is that the project land must have been cleared of vegetation and had its regrowth actively suppressed for at least 10 years prior to commencement. The project must demonstrate potential to achieve a forest cover threshold, generally defined as trees reaching at least 2 metres in height with a 20% canopy cover. To facilitate this natural regeneration, Landscape Aggregation employs activities such as ceasing the mechanical or chemical destruction of regrowth, carefully managing the timing and extent of livestock grazing, and controlling feral animals in a humane manner.

The Paroo Shire region surrounding the project area is characterised by a semi-arid climate with high summer temperatures and low, highly variable rainfall. The local environment consists mostly of flat, open plains where soils typically feature red earths, clays, and sandy loams. Consistent with the broader outback Queensland landscape, the region's primary land use is extensive pastoral agriculture, specifically dedicated to sheep and beef cattle grazing.

Originally registered under the name "Climate Friendly Aggregation Project No. 3", the project officially changed its name to Landscape Aggregation in February 2020. It has proven to be an active carbon sequestration initiative, having been issued a total of 174,845 Australian Carbon Credit Units (ACCUs) to date. In September 2025, the participant structure was updated to remove Corporate Carbon Solutions Pty Ltd, leaving Catherine Mary Barden and Robert Alfred Barden as the sole registered project proponents. Because of its substantial size, the project area has also been evaluated in national academic studies monitoring the compliance and vegetation recovery rates of Australian HIR offset projects.
