Headline indicators for KMGBF goal A and its associated targets, for which a current methodology is already agreed [28].

focus	headline indicator(s)
Goal A: integrity, connectivity and resilience of all ecosystems maintained, enhanced or restored, substantially increasing area of natural ecosystem by 2050. Anthropogenic extinction of known threatened species halted by 2050, with the extinction rate and risk of all species reduced by 90% and the abundance of native wild species increased to healthy levels. Genetic diversity maintained within populations of wild and domesticated species.	Red List of Ecosystems
	Extent of natural ecosystems
	Red List Index
	The proportion of populations within species with an effective population size >500
Target 1: plan and manage all areas to reduce biodiversity loss.	Red List of Ecosystems
	Extent of natural ecosystems
Target 2: restore 30% of all degraded ecosystems.	(none)
Target 3: conserve 30% of land, waters and seas.	Coverage of protected areas and other effective area-based conservation measures
Target 4: halt species' extinction, protect genetic diversity and manage human–wildlife conflicts.	Red List Index
	The proportion of populations within species with an effective population size > 500
Target 5: ensure sustainable, safe and legal harvesting and trade of wild species.	Proportion of fish stocks within biologically sustainable levels
Target 6: reduce the introduction of invasive alien species by 50% and minimize their impact.	Rate of invasive alien species establishment
Target 7: reduce pollution to levels that are not harmful to biodiversity.	Index of coastal eutrophication potential
Target 8: minimize the impacts of climate change on biodiversity and build resilience.	(none)
