Darling River Eco Corridor 5

Human Induced Regeneration

Taking it’s name from the uniquely Australian tree that seems to ooze blood instead of sap, Bloodwood is host to a lake system that has the richest array of fairy shrimps, clam shrimps and shield shrimps in the world. As lifetime environmental advocates, it obviously held great appeal for Sue Hanson and her family, who took it over in 2008.

The sheer diversity of the property was a key selling point, and thanks to their two carbon projects, the Hansons have continued to invest in the property to the point where they regard it now as ‘completely set up’.

Sue says the ecosystem at Bloodwood can now effectively work on its own, because the carbon income gives them the luxury of being able to let it repair in the seasons when they don’t need to keep groundcover down, and then allow it to rest and recover to maintain its rich biodiversity.

Investment from the carbon project has included a rigorous feral animal control program, and extensive fencing, yard and watering programs. The financial buffer of the carbon money enables Sue to manage stock on the land without putting undue pressure on what is a fragile landscape. “Now we can manage the land with environmental sensitivity, and that has been a gift to us,” says Sue.

Bloodwood now employs someone to help with grading, maintaining the project area, and keep on top of feral animal control. They even take on agistment cattle after good years, with the confidence the land will be able to maintain its health and diversity.

Human-Induced Regeneration of a Permanent Even-Aged Native Forest – 1.1 Methodology Determination 2013

This map shows the project area boundary and the different elements of project design including the carbon estimation areas and exclusion areas.  This stratification may reflect both initial stratification and subsequent revisions.

In order to inform the initial stratification of the Darling River Eco Corridor 5 HIR project in accordance with the Determination, GreenCollar carried out field surveys and data collection.  This included collection of data on existing vegetation species, photos and a detailed site description.

Satellite imagery and remote sensing datasets were used to identify eligible land and exclusion areas. The extent of exclusion areas (totalling 11,274 ha), comprised of pre-existing forest cover (710 ha) and areas which classified as having no forest potential (1,670 ha). Through this process a final eligible CEA area of 13,460 ha was confirmed.

This maps shows a current satellite image of the project area.  Satellite imagery and remote sensing datasets were used to identify eligible land and exclusion areas.

This map shows a summary of all CEA and Exclusion Areas.


Project Sequestration and Abatement


This version of the HIR Methodology requires using Full Carbon Accounting Model (FullCAM) to determine the sequestration of carbon stocks and emissions required to calculate the net abatement amount for each reporting period. The carbon dioxide equivalent net abatement amount in relation to a reporting period for the project is taken to be the change in carbon stock for the project area less the project emissions. Any carbon stock that accumulated by the crediting start date for the project is calculated as the initial carbon stock and is removed from the calculation of abatement as the proponent is not entitled to credits for it.

See below for the average per hectare sequestration for the Darling River Eco Corridor 5 HIR project.

Implementation & Monitoring


The activities for the project are:

  • the management of the timing & extent of grazing, and
  • the management, in a humane way, of feral animals

Since project commencement these activities have been undertaken across the project area to assist the regeneration of native forest in attaining forest cover. Once the initial offsets report has been completed, GreenCollar works closely with the land manager of the project property to collect land management information every quarter. This is reviewed and reported on in each offsets report.

A summary of monitoring activities and evidence collection undertaken on this project is set out below:

  • Evidence collection in relation to grazing and herd management
  • Evidence collection in relation to removal and reduction of feral animals
  • Evidence of fire management activities
  • Evidence collection from land manager as to other land management activities as relevant
  • Change detection assessments
  • Repeat biomass inventory surveys to track biomass change of regenerating vegetation
  • Daily fire hotspot monitoring and review of Seasonal Fire Risk
  • Review of SPEI drought index
  • Regeneration Gateway Checks

These surveys are currently not required under the HIR method but are implemented by GreenCollar to provide additional assurance that biophysical threats to carbon stores such as grazing, drought and fire are not negatively impacting the regeneration and to track progress of regeneration of the native forest. In addition, the data collected is utilised for broader research purposes.

This map shows the points within the project area where vegetation biomass surveys were conducted as part of the monitoring process.

A Biomass Waypoint is a randomly allocated point within the project area where sampling data is collected.

Regeneration Checks


The Guidelines require that Proponents must provide regeneration checks at least once every five years from the start of the project’s last or only crediting period until CEAs pass their forest cover assessment date[7], and upon request by the Clean Energy Regulator.

A summary of regeneration checks required for the Darling River Eco Corridor 5 HIR Project is set out below:

Regeneration Check: Year 6

7.5% canopy cover at 100ha scale[8]

09 June 2021 – Completed
Regeneration Check: Year 10

10% canopy cover at 10ha scale[9]

09 June 2025
Forest Cover Assessment Date [10] 09 June 2031

The process and methodology includes one or more of the three evidence requirements and reporting:

  • Evidence level 1: Change detection analysis, or
  • Evidence level 2: Remote sensing analysis and/or
  • Evidence level 3: Field data; and
  • Reporting

[6] The initial stratification was reported on prior to the public release of the Guidelines on stratification, evidence and records in May 2019. These guidelines also set out administrative arrangements for projects that have previously reported, including a pragmatic approach that will be taken in situations where additional evidence is required to meet these guidelines. Additionally, the project is defined as an existing project in accordance with Section 9AA of the CFI Rule 2015.
