Affected species by IUCN extinction risk
Measurement answer
What this metric measures
Species affected or potentially affected in a stated area, retained by taxon and the cited global, regional, or national IUCN extinction-risk assessment and its version.

Reporting boundary
One distinct taxon, extinction-risk assessment scope, and affected-area relationship at the reporting date. Global, regional, and national assessments remain separate and no bulk Red List dataset is redistributed.

- Structured table — see field-level units
- Reporting basis
- Assessment snapshot as of the reporting date
Unit meaning: This metric is reported as a structured table; each field carries the unit stated in the table fields below.
Table fields and units
- Accepted taxon, synonym, site or affected-area polygon, and actual or potential relationship
- Assessment scope (global, regional, or national), IUCN category, publication date, and version
- Species record (one taxon-assessment-scope-area relationship)
- Source URL or licensed reference, data-access rights, habitat proxy, and reporting date
- Distinct-taxon roll-up key and deduplication scope, if reported
Published dimensions
- Taxon, affected area, relationship state, assessment scope, category, version, and rights

No single formulaPopulate the structured fields from qualifying source observations and retain each field-level unit, boundary, status, and method; do not collapse the disclosure into one calculated value.
Verified sources
Evidence and status sources
Sustopedia checked each record-specific claim directly against primary publisher material. Labels distinguish current measurement authority from future compatibility and corroborative, legal, edition, or method status context. Corroborative evidence can support a stated limitation but cannot establish the core measurement by itself.

Source-edition basis: Effective GRI 101: Biodiversity 2024 guidance, binding ESRS E4-5, and IUCN Red List Categories and Criteria version 3.1 second edition as restricted factual references.
- Name accepted taxon, synonym, site or polygon, and actual or potential relationship.
- State global, regional, or national assessment scope, IUCN category, publication date, and framework version.
- State source URL or licensed reference, data-access rights, habitat proxy where used, and reporting date.
- Treat one species record as one taxon-assessment-scope-area relationship, not an enterprise-caused risk count.
- For roll-ups, state the explicit distinct-taxon view and preserve assessment-scope separation.
Record-specific limitations
- An IUCN category describes extinction risk, not enterprise causation, local population state, or conservation priority.
- Global, regional, and national categories for the same taxon can differ and are not interchangeable.
- Taxonomy and assessment dates can be stale, and data use remains subject to source and licence rights.
Interpret this metric with the stated reporting boundary, period convention, value shape, and unit. Results prepared with different boundaries or conventions may not be directly comparable.
Measurement evidence supports the core record-specific claims described above. Corroborative evidence can support limitations, while compatibility and status sources provide their separately labelled context. None of these cards by itself determines an organisation's legal applicability, filing readiness, assurance status, or compliance conclusion.
