Disclosure form
No single formulaReport the source-defined result with its stated fields and method disclosures. This is a standalone, quantitatively reportable additional-sector metric with an explicit area unit, organizational management boundary, and required species-type disaggregation. It is not equivalent to the shortlisted ESRS area-covered metric because it measures area under control or management rather than area covered by invasive alien species.
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: TNFD sector guidance, Final English sector guidance collection through August 2026 (17 documents).
- Describe the basis used to identify colonization by invasive alien species.
- Disclose the invasive alien species type associated with each reported managed or controlled area.
- State the organizational area included in the reported control or management boundary.
Record-specific limitations
- The disclosed area identifies land under control or management and does not, on its own, demonstrate management effectiveness or successful eradication.
- The source specifies a species-type breakdown but does not provide an aggregation rule for areas affected by more than one species.
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.
