A BAM biodiversity expert is someone that the Secretary of the department (or their delegate) has approved to prepare an expert report for inclusion in a Biodiversity Assessment Report. They do not need to be an accredited assessor or have attended BAM training.

BAM biodiversity experts have specialised knowledge to provide an expert opinion about an individual threatened species on a site to:

  • determine its likely presence or absence
  • identify its habitat without survey
  • estimate its density and map the extent of habitat.

Expert reports

An expert report, developed in accordance with Box 3 of the BAM, can be used to determine species presence on land proposed for development, clearing activity, biodiversity certification or stewardship.

An expert report can only be used for species credit species and habitat assessed as a species credit or dual credit species. NSW BioNet houses information on the credit type for a threatened species.

An approved BAM biodiversity expert must prepare an expert report.

The BAM biodiversity expert must determine:

  • the likely presence or absence of the species on the subject land
  • if present, map the species polygon.

Learn about BAM biodiversity experts in Box 3 (in section 5) of the Biodiversity Assessment Method (BAM) 2020.

Applying to become a BAM biodiversity expert

A BAM biodiversity expert is a person who the Secretary of the department (or delegate) considers has specialised knowledge relevant to the threatened species being assessed. They do not need to be an accredited assessor or have attended BAM training.

To be listed as a BAM biodiversity expert, individuals must submit an application that addresses all the following criteria:

  • academic qualifications such as relevant degrees and postgraduate qualifications  
  • history of experience in the ecological research, habitat assessment and survey method methods for the relevant species
  • a resumé detailing projects relating to the survey of the relevant species (including the locations and dates of the work), their employers' names and periods of employment (where relevant) over the previous 10 years
  • peer-reviewed publications on the species or other evidence that the person is a well-known authority on the species to which the survey relates (the assessor cannot act as a referee for the proposed expert for this purpose).

Preparing an expert application

Applications are to be emailed to the Biodiversity Assessment Method species expert mailbox at [email protected].

Applications must include a signed application form and all supporting evidence. Ensure supporting evidence is provided for each species included in the application and clearly indicate which species and section of the application each attachment relates to.

A maximum of 4 species can be included in an application. If you are applying for more than 4 species, you must submit multiple applications. 

Additional guidance is included in the application form.

Conflict of interest declaration

Section 5 of the application form includes a conflict of interest declaration. 

The department may determine not to approve applicants where an actual, reasonably perceived or potential conflict of interest is identified that cannot be appropriately managed. The department may revoke a BAM biodiversity expert determination if an actual, perceived or potential conflict of interest is identified and cannot be appropriately managed.

A BAM biodiversity expert cannot act in the following high-risk circumstances:

  • the expert, or their family member or close personal relation, is the proponent of an activity where the BAM applies, and the species for which they are an approved BAM biodiversity expert is required to be assessed
  • the expert, or their family member or close personal relation, owns or trades in credits relating to the species for which they are an approved BAM biodiversity expert
  • the expert, or their family member or close personal relation, is proposing to enter a new or vary an existing biodiversity stewardship agreement involving the species for which they are an approved BAM biodiversity expert.

Applicants must disclose any other circumstances where there is an actual, perceived or potential conflict of interest. BAM biodiversity experts must notify the department if their circumstances change and a new actual, perceived or potential conflict of interest is identified. 

For a copy of the conflict of interest declaration form, contact the department at [email protected]. 

Accredited assessors wishing to apply to become a BAM biodiversity expert must refer to clause 2(a) of the Accredited Assessor Code of Conduct regarding specific conflicts of interest related to undertaking the requirements of a BAM biodiversity expert.

List of approved BAM biodiversity experts

The Secretary of the department may:

  • publish a list of experts – this is not intended to be comprehensive and may have conditions and limits on the expert listing (for example, restrictions to certain regions of New South Wales)
  • remove people from the list if, in their opinion:
    • the BAM biodiversity expert no longer has specialist knowledge 
    • the BAM biodiversity expert behaves unprofessionally
    • an actual, perceived, or potential conflict of interest is identified and cannot be appropriately managed.

Before removing the BAM biodiversity expert from the list, the person will be notified and given adequate opportunity to respond.

A person not on the published list of experts may be contracted to prepare an expert report but must be approved by the Secretary of the department (or delegate) before any Biodiversity Assessment Report is submitted that relies on expert report outcomes.
