Associate Professor (Honorary) Cris Brack, a forestry expert from the Australian National University, has completed his latest review of the human-induced regeneration (HIR) gateway checks.
Assoc Prof Brack has reviewed an additional 16 projects that have completed HIR regeneration checks since his December 2024 report. This report adds to the series of independent reviews of the process and outcomes of the HIR gateway checks that began in 2023.
Assoc Prof Brack’s analysis of data provided in 2025 confirm conclusions from his 2024 reports, including:
- the current mix of audit reports, reviews by the Clean Energy Regulator and new s215 audits provide strong assurance that projects are being managed appropriately
- stratification and classification methods used for carbon estimation areas (CEAs) were suitable
- national-scale models of tree cover can be unreliable for CEA evaluation, especially in Western Australia.
