BioBanking Assessor resources

A range of resources is available to assist assessors

The Biodiversity Offsets Scheme under the Biodiversity Conservation Act 2016 commenced on 25 August 2017 visit Biodiversity Offset Scheme.

Field data sheets

Field data sheets can be used by assessors to record transect and plot data for a biobank or development site. Field data sheets for BioBanking: biobank/development site includes instructions for carrying out field work, descriptions of key terms as well as a landscape value assessment sheet, transect plot data sheet, transect tally table and a transect plot worksheet. Download either:

Plots template

The plots template (CSV 1KB) is a form used to import transect and plot data into the credit calculator, following the steps set out in the operational manual.

Establishing a local benchmark

The local benchmark calculator spreadsheet (XLS 35KB) assists BioBanking Assessors to calculate a local benchmark from transect and plot data collected at a local reference site or from published data. Local benchmarks must be developed in accordance with the methodology and the procedures set out in the operational manual. The Field data sheets for BioBanking: local reference site data can be used by assessors to record transect and plot data for a local reference site to establish a local benchmark. Download either:

Converting credits to hectares

A tool that converts credits to hectares was developed for Biodiversity Certification proposals as set out in section 9.3.1 of the Biodiversity Certification Assessment Methodology (PDF 236KB). The Credit Converter (XLS 173KB) is an estimation tool to convert a quantity of ecosystem credits and/or species credits required for a development into an estimate of the area of land that would be required as an offset. The Credit Converter can also be used to estimate the likely costs of an offset based on land value and management costs. Please see the instructions page in the Credit Converter for more information.

Paddock tree calculator

The paddock tree calculator spreadsheet (XLS 49KB) assists users to assess areas containing scattered paddock trees. It can be used to determine whether the area is in low condition or not, and to calculate the effective clearing area. Detailed guidelines on the survey methods used to assess scattered paddock trees are contained in the operational manual.

Threatened species survey methods for 'species credit' species

Threatened species that can't be reliably predicted to occur on a development site or a biobank site, based on plant community type, distribution and habitat criteria, are identified by the Threatened Species Profile Database (TSPD) as 'species credit' species. This includes all threatened plant species, and a subset of the fauna species.

Assessment of these species may require a targeted survey to determine their presence and distribution on the subject site. Field survey methods used to survey for these species should be described in the Biodiversity Assessment Report (BAR). Guide to surveying threatened plant species (OEH 2016) and the Threatened species survey and assessment guideline for amphibians (DECC 2009) provide more precise information about survey effort required to establish the presence or absence of individual plant and amphibian species.
