Notes

Note that this metric may be derived from Ecosystem asset accounts (see Ecosystem assets tab). Additional analysis may be required to determine the extent to which measured change in extent of introduced/invasive/weed/pest species, varieties or strains has been caused by the reporting entity. ‘Affected by’ could be defined more specifically as the flow of ecosystem services depended on by the reporting entity are significantly reduced (remain above levels required to meet objectives), and/or management of this issue entails significant cost (above expectations). Variants of this metric include TNFD <https://tnfd.global> additional disclosure metric A4.0: “Number/extent of unintentionally introduced species, varieties or strains in areas owned, operated, used or financed in priority areas (absolute, presence/absence and/or number removed).”
