Indicator description

The indicator is simply a total number of species whose extinction was prevented through conservation interventions (that mitigated or reduced threats and/or overcame barriers to recovery), thereby reducing or reversing declines that would otherwise have led to extinction within a specified period. The methods were published in Butchart et al. (2006).

Current storyline

This indicator has shown that 16 bird species would have gone extinct during 1994-2004 without conservation interventions.

Data and methodology

Coverage: Global/Regional

Scale: Global data

Time series available: 1994-2004 (will update to 2010-2020)

Next planned update: 2019/2020

Possible disaggregations: Birds/mammals

Methodology: To identify those species for which conservation may have prevented extinction during a particular period, candidates are identified as those species that have a minimum population estimated to be <100 individuals at the beginning of the period, or had a population that was estimated to be <200 individuals and estimated, inferred or suspected to be declining at a rate >80% over 10 years or three generations (whichever was longer, as specified in the IUCN Red List criteria; IUCN, 2001), and that received direct conservation interventions during the period that significantly mitigated a key threat to the species. Then for each species, the likelihood is assessed that they would have failed to survive if conservation action for them had ceased at the beginning of the period, considering the population size, trends, severity of threats and intensity and effectiveness of conservation interventions.

Work is planned to produce a 2010-2020 update for birds and mammals, in collaboration between IUCN, BirdLife International and CNRS, through the INSPIRE4Nature project.http://www.inspire4nature.eu

National use of indicator

The same approach could be adopted at a national scale, but is complicated by the potential for ‘rescue’ by populations in other countries, and this approach has not been applied to date.
