Landscape Aggregation

Landscape Aggregation is a Human-Induced Regeneration (HIR) carbon project located on Valetta Station, approximately 80 to 100 kilometers south of Cunnamulla in South West Queensland. Registered in April 2016, the project covers a significant area of 19,367 hectares within the Paroo Shire, a region traditionally dedicated to sheep and cattle grazing. The property is owned and managed by the Barden family (Robert and Catherine Barden), who are long-term graziers in the district and well-known for operating the "Bardo's Dohnes" sheep stud.

The project operates under the Human-Induced Regeneration (HIR) methodology, which credits landholders for allowing native forests to regenerate on land where regrowth was historically suppressed by activities such as mechanical clearing or grazing. Instead of planting new trees, the project involves changes in land management, specifically the cessation of mechanical clearing and the strategic management of grazing pressure, to facilitate the natural recovery of the native vegetation. This forest regeneration captures carbon dioxide from the atmosphere, generating Australian Carbon Credit Units (ACCUs).

Situated in the Mulga Lands bioregion, the area is characterized by a semi-arid climate with irregular rainfall and soils that are typically red earths or sandy loams. The vegetation is dominated by Mulga (Acacia aneura) and Poplar Box woodlands, which are resilient to the dry conditions but require careful management to regenerate effectively. The project was originally registered as "Climate Friendly Aggregation Project No. 3" before being renamed in 2020, and recent administrative variations in 2025 saw the removal of corporate service providers from the proponent list, leaving the Barden family as the sole project proponents.
