Method Catalogue.
Welcome to the Accounting for Nature® Method Catalogue. It serves as a repository of accredited methodologies designed to facilitate the build of an Environmental Account.
Selecting or creating an Accredited Method is an essential step in following the Accounting for Nature® Framework and preparing an Environmental Account.
The catalogue offers a selection of accredited methodologies designed to detail measurement and reporting requirements on environmental assets, tailored to diverse regions, ecosystems, and sub-regions. Users of the Accounting for Nature® Framework must select a method for each environmental asset in an Environmental Account.
Methods listed in the catalogue include key details to help you choose one that is most appropriate for your purpose. Importantly, each method identifies what type of expertise is required or recommended to implement the method. Where a method requires an expert with specific skills, Accounting for Nature will require evidence of these skills at the account registration and certification steps. If the expert is already accredited as an Asset Expert, additional evidence will not be necessary.

Method ID: AfN-METHOD-F-03
Status: Approved 14 December 2021
Accuracy: Moderate (80%)
Scale: Regional Scale
Location use: Global
Summary: Threatened species assessments by expert committees are an important tool for understanding the extinction risk of species at a continental scale or state scale, aiding the prioritising and conservation management of at-risk species. But it is also important to understand the conservation status of native species at regional scale, as this is often the scale at which conservation management is applied by organisations such as NRM Regions and Local Governments. The Method focuses on terrestrial, freshwater, and coastal vertebrate species including mammals, birds, reptiles, amphibians, and fish. The Method is based on an elicitation process where experts in the ecology and management of vertebrate taxa are provided a compilation of available data and are guided through a structured decision-making process by an expert elicitation specialist. Producing a regional fauna Environmental Account can provide communities with a greater understanding of the conservation status of their local fauna and inform regional conservation initiatives.
Data Collection: Expert Elicitation
Stratification: Non spatial vertebrate groups – mammals, birds, reptiles, amphibians, fish.
Indicators: Each species within an animal group is assigned a Red List Category, these are aggregated to give a measure of current extinction risk status (ER) for the animal group. The red list index is then calculated for the species group by comparing the current extinction risk and the potential extinction risk (if all species were extinct).

Method ID: AfN-METHOD-F-07
Status: Accredited 11 June 2026
Accuracy: High (90%)
Scale: This Method is applicable at the project, property, and aggregate scale. Assessment units must be at least 1 ha, with no maximum size.
Location use: Any terrestrial ecosystem globally.
Summary: This Method has been developed to assess the condition of a target faunal group (environmental asset) within the fauna asset class. The target faunal group can be defined at the level of either taxonomic class (e.g. birds, mammals), or a subset of species within a taxonomic class (e.g. ground nesting birds, medium-large ground dwelling mammals) depending on the scope and purpose of the Environmental Account. Data is collected in the field using camera traps, where the basic unit of measure is the detection (presence) or non-detection (absence) of a species on a particular day and at a particular site. Detection/non-detection data is used to estimate species occupancy for native fauna using site occupancy models, and naïve occupancy estimates are used for non-native fauna. Condition scores are calculated by comparing species occupancy estimates to benchmarks for species within the target group, and the Econd® is calculated by aggregating the condition scores for native and non-native fauna across the Asset Account.
Data Collection: Data is collected using wildlife cameras that use an infra-red sensor to detect the movement of an animal and trigger the camera. Camera trap protocols can be tailored to maximise the detectability of species within the target faunal group.
Stratification: The Asset Account must be stratified into assessment units that are a unique combination of broad habitat type (e.g. woodlands, grasslands) and broad condition state (e.g. cleared, regrowth, disturbed, remnant).
Indicators: The Econd® score is derived using two indicators of fauna condition: a native fauna indicator and a non-native fauna indicator.
Expertise: This Method is best suited for application by skilled environmental practitioners. Users must have experience in fauna monitoring programs with high-level skills in fauna species identification, basic GIS skills, and an understanding of camera trapping protocols, data management, and site occupancy modelling.
Limitations:
Species occupancy is an estimate of occurrence (presence/absence). The scoring approach used in this method is not considered to be well suited to account for overabundance.
A naïve occupancy threshold of 0.2 determines the eligibility of a species for inclusion in site occupancy modelling. Some species (e.g. rare or cryptic species) may not meet this threshold and may be excluded from target faunal groups.
Species detection is imperfect and a species may be present but not detected. The Econd® may be underestimate fauna condition in these instances.

The Econd® score measures the similarity between an assessment unit and its reference site based on their species and functional composition.
Data Collection: Field sample collection by account developer and lab analysis by NatureMetrics.
Stratification: The Accounting area must be stratified into assessment units. Sites within each assessment unit must have similar soil characteristics and be within 100 km of each other. Each assessment unit is paired with a reference site.
Indicators: Five indicators are provided from eDNA-based surveys and include three groups: bacteria, fungi and invertebrates. Beta diversity of species is used for all three groups, and the beta diversity of functions are included for fungi and bacteria.
Expertise: This Method requires the Account Holder to define the accounting area, including a map, table and description of assessment units and reference sites, and their extent (in hectares). The subsequent data collection plan and environmental indicators will be reviewed and approved by NatureMetrics before implementing the Method. The Method requires the expertise of NatureMetrics to support with survey design, to process and analyse soil samples, and to calculate the Econd® of soil biota.
Licence: Licenced, fee required, contact NatureMetrics for more information.
Embargo Period: 3 years (ending November 2028)
Method developers have the option to withhold publication/public use of their method for up to 3 years. If a user wishes to view a method that is “under embargo,” they must contact us. We will request permission from the Method Manager to share the method with the user, subject to a Method Non Disclosure Agreement being signed. The user has one week to view the method.
Methods In Development.
In addition to our catalogue of Accredited Methods, we are actively working with collaborators on new tools to expand the Accounting for Nature® Framework. These methods in development aim to address emerging needs in environmental measurement and accounting. Explore the number of methods currently in development stage.
Have a method idea?
At Accounting for Nature, we understand that every environmental context is unique, and sometimes, the method you're looking for might not exist yet. If you have specific requirements or innovative ideas, developing your own method can be a rewarding and impactful process.
