This method is closed – new projects can’t be registered.

The human-induced regeneration of a permanent even-aged native forest (HIR) method expired on 30 September 2023.

Projects that started their crediting period before the method expired aren’t affected. They’ll continue for the duration of their crediting period.

You can refer to our guidance for ACCU Scheme participants impacted by the expiry or sunsetting of an ACCU Scheme method for more information.


An HIR project introduces new land management practices to regenerate native forests. These practices help native forests to regrow where they were previously being suppressed through:

  • livestock
  • feral animals
  • plants not native to the area
  • mechanical or chemical destruction, or suppression, of regrowth.

Earn Australian carbon credit units (ACCUs) when carbon is stored after eligible activities.

Benefits of running an HIR project are:

  • improved quality of your land and water supply
  • increased biodiversity
  • shade and shelter for stock.


There are exclusions under this method:

  • Biomass can’t be removed from carbon estimation areas (CEAs), unless:
    • removal is required by law
    • removal of non-native plants is likely to improve the condition of remaining native vegetation
    • it’s dead not from mechanical or chemical destruction.
  • Direct seeding or planting
  • lime or fertiliser use
  • Conservation land, where mechanical or chemical suppression has occurred during the baseline period.

Native vegetation must not be mechanically or chemically damaged or destroyed within a CEA unless it:

  • is required by law
  • improves the growth rate or health of the remaining native vegetation.

Your project area must not have any forest cover during the 10-year baseline period. The baseline period is determined by date:

  • For new projects, the baseline period is the 10 years before the project application date.
  • For project variations, the baseline period is the 10 years before the application to vary the project area was submitted.

Relevant legislation:

  • Section 12(2) of the method
  • Section 23 of the method
  • Sections 4-5 of the method.

Method requirements

This method is a variation of the original version first released in 2013

Key changes from the original version are:

  • changing from Reforestation Modelling Tool (RMT) to Full Carbon Accounting Model (FullCAM)
  • it carries forward negative abatement from one reporting period to the next
  • it clarifies arrangements for adding new project areas, transferring a project from another method and transferring project areas from another method
  • it allows projects to be conducted on conservation land

Projects that have started their crediting period can continue to use the version of the method they're originally registered to.

The method the project is registered under continues to apply until the end of the crediting period.

As this method is now closed, you cannot add or change areas to your project.

Project activities are only eligible when implemented on land where native forest's been suppressed for at least 10 years before project start date.

Activities can be:

  • excluding livestock and taking reasonable steps to keep livestock excluded
  • managing the timing and extent of grazing
  • managing feral animals in a humane manner
  • managing plants that are not native to the project area
  • stopping the mechanical or chemical destruction, or suppression, of native forest regeneration.

A CEA is part of the project area where eligible activities are implemented to regenerate native forest. The amount of modelled regeneration within CEAs is used to calculate abatement.

Livestock grazing can be permitted only to the extent where it doesn’t impact the regenerated vegetation. This requires:

  • managing the timing and extent of grazing in a CEA
  • ensuring forest cover is achieved.

A project activity conducted on conservation land is limited to:

  • managing feral animals in a humane manner
  • removing plants non-native to the project area.

Activities on conservation land must demonstrate being beyond what is usually required in managing conservation land.

Activities undertaken must also connect back to the demonstrated suppressor and be linked to removing that suppression. This is called a casual relationship. You must be able to demonstrate this casual relationship when reporting.

Relevant legislation
  • Part 5 of the Act

Net abatement for each reporting period is calculated by the change in amount of carbon stored in all CEAs. This is minus emissions from fire and fuel used while implementing eligible activities. Net abatement is adjusted if there’s any negative carry over from previous reporting periods.

If your project was registered under the original variation of this method, you must use the Reforestation Modelling Tool (RMT) to calculate abatement.

For projects under the later variation, you must use FullCAM to calculate the amount of carbon stored and the emissions from biomass burning in all CEAs in the project area.

There are variations of FullCAM that you can use. They depend on when your project started.

You can refer to our guide to the 2020 FullCAM – transition arrangements to find which version of FullCAM to use.

Relevant legislation
  • Sections 25–37 of the method

You must monitor CEAs for:

  • compliance with project operation requirements, including monitoring:
    • removal of biomass
    • restriction on mechanical or chemical destruction of native vegetation
    • restriction on livestock and restriction on use of lime and fertiliser
  • management activities and disturbance events such as fire.

You must also meet general monitoring requirements of the Act.

Relevant legislation:
  • Part 17 of the Act
  • Part 17 of the rule
  • Sections 42–43 of the method

You must keep records relating to:

  • project baseline suppression activities
  • plant species being regenerated
  • stratification into CEAs
  • the modelling commencement date
  • project activities
  • fires
  • fuel use
  • FullCAM modelling.

You must keep records according to the general record-keeping requirements of the Act and rule.

Relevant legislation
  • Part 17 of the Act
  • Part 17 of the rule
  • Sections 40–​41 of the method​
  • Section 44 of the method

You must submit reports anywhere between 6 months to 5 years. Reports must be submitted within 6 months after the end of the reporting period.

A minimum of 5 reporting periods in a crediting period is required.

Your reports must include:

  • net abatement amounts
  • CEAs and modelling points on a geospatial map
  • data on emissions from biomass burning and fuel use
  • FullCAM files and output data
  • project activities and how they're undertaken

Projects under this method are regeneration projects. They're required to submit additional information demonstrating how the CEAs are progressing towards being able to achieve forest cover at certain gateways, being approx. year 5 and year 10.

Learn more about gateways and demonstrating progress towards and achieving forest cover in the guidelines on stratification evidence and records for HIR and NFMR.

You can use our recommendation 8 guidance to ensure your reports demonstrate a causal relationship between HIR activities and the suppressors. 

You must also remember to meet the general reporting and notification requirements of the Act, the rule and the method.

Relevant legislation
  • Part 6 of the Act
  • Part 6 of the rule
  • Sections 9AA and 70(3A) of the rule
  • Section 15 of the method
  • Sections 38–39​​ of the method

Regeneration checks and forest cover attainment checks (gateway checks) for HIR projects are subject to a section 215 gateway audit for compliance. Learn more about HIR gateway audit requirements. 

We expanded the annual audit program to cover HIR gateway checks. You'll receive a written notice if you’re subject to a s215 gateway audit.

The notice includes:

  • who the appointed auditor is
  • the period the audit covers
  • the scope and matters to be covered by the audit
  • when the audit will occur.

We cover the cost of the audit and commission an independent expert to regularly review and report on HIR gateway checks for publication. This provides transparency about the outcome of gateway checks across the HIR project portfolio.

ACCUs are issued when the requirements of a gateway check are met.

As with all projects, we provided you with an audit schedule when your project was declared. You must provide audit reports according to this schedule.

We schedule at least 3 audits, and additional audits can be triggered.

For more information on audit requirements, you can refer to our audit information.
