Abstract
Recognizing the imperative to evaluate species recovery and conservation impact, in 2012 the International Union for Conservation of Nature (IUCN) called for development of a “Green List of Species” (now the IUCN Green Status of Species). A draft Green Status framework for assessing species’ progress toward recovery, published in 2018, proposed 2 separate but interlinked components: a standardized method (i.e., measurement against benchmarks of species’ viability, functionality, and preimpact distribution) to determine current species recovery status (herein species recovery score) and application of that method to estimate past and potential future impacts of conservation based on 4 metrics (conservation legacy, conservation dependence, conservation gain, and recovery potential). We tested the framework with 181 species representing diverse taxa, life histories, biomes, and IUCN Red List categories (extinction risk). Based on the observed distribution of species’ recovery scores, we propose the following species recovery categories: fully recovered, slightly depleted, moderately depleted, largely depleted, critically depleted, extinct in the wild, and indeterminate. Fifty-nine percent of tested species were considered largely or critically depleted. Although there was a negative relationship between extinction risk and species recovery score, variation was considerable. Some species in lower risk categories were assessed as farther from recovery than those at higher risk. This emphasizes that species recovery is conceptually different from extinction risk and reinforces the utility of the IUCN Green Status of Species to more fully understand species conservation status. Although extinction risk did not predict conservation legacy, conservation dependence, or conservation gain, it was positively correlated with recovery potential. Only 1.7% of tested species were categorized as zero across all 4 of these conservation impact metrics, indicating that conservation has, or will, play a role in improving or maintaining species status for the vast majority of these species. Based on our results, we devised an updated assessment framework that introduces the option of using a dynamic baseline to assess future impacts of conservation over the short term to avoid misleading results which were generated in a small number of cases, and redefines short term as 10 years to better align with conservation planning. These changes are reflected in the IUCN Green Status of Species Standard.

This work would not have been possible without the countless hours volunteered by species experts around the globe, including many assessors who did not choose to be listed as authors. We thank the IUCN Species Survival Commission and Red List Unit for their help coordinating this input and to the National Geographic Society for supporting a suite of test assessments. Workshops were funded by the Prince Albert of Monaco Foundation (administered via the Cambridge Conservation Initiative Collaborative Fund) and by Fondation Franklinia. We thank Global Wildlife Conservation for their help coordinating the workshops. Special thanks are due to A. Rodrigues for her active involvement in every stage of developing the IUCN Green Status of Species. We thank T. Kuiper for help with data analyses and M. Clark for commenting on an early draft. M.G. was supported by a NERC Knowledge Exchange Fellowship and the IUCN SSC and the World Wildlife Fund. H.R.A. was supported by the Stony Brook University OVPR Seed Grant Program.
