Tracking these 5 changes is crucial to understanding species status, adjusting conservation strategies, and 6 assessing the performance of the ESA. We helped develop and test novel metrics that track 7 changes in recovery status using six components. ESA 5-year status reviews provided all of the 8 information used to apply the recovery metrics. When we analyzed the reviews, we observed 9 several key challenges to species recovery. First, the reviews lack a standardized format and 10 clear documentation. Second, despite having been listed for decades, many species still lack 11 basic information about their biology and threats. Third, many species have continued to decline 12 after listing. Fourth, many species currently have no path to recovery. Applying the recovery 13 metrics allowed us to gain these and other insights about ESA implementation. We urge the U.S. 14 Fish and Wildlife Service to adopt the metrics as part of future status reviews in order to inform 15 public discourse on improvingFor conservation Peer policy Review and to systematically track the recovery 16 progress of all ESA species. 17 3 Page 5 of 23 1 Introduction 2 To effectively conserve imperiled species, accurate information of a species’ conservation status 3 must be readily available to inform management decisions (IUCN Standards and Petitions 4 Committee, 2019; Bayraktarov et al., 2021). Under the U.S. Endangered Species Act (ESA), no 5 concise, standardized metrics exist for assessing changes in species recovery status (Malcom et 6 al. 2016). Instead, the changes are often evident only when a species’ ESA legal classification 7 changes (i.e., uplisted, downlisted, or delisted). For most ESA-listed species, however, these 8 reclassifications are very rare or nonexistent, making it impossible for them to capture subtle but 9 important changes in recovery progress (USFWS, 2018). For example, a species may require 20 10 years for recovery and delisting from the ESA. During this time, the species may be progressing 11 toward recovery but not enough to trigger a reclassification. Tracking this progress is crucial to 12 understanding species status, adjusting conservation strategies based on this status, and assessing 13 the performance of the ESA. 14 15 The ESA requires the U.S.For Fish and Peer Wildlife Service Review (USFWS) or the National Marine Fisheries 16 Service (NMFS; hereafter “the Services”) to review the status of every listed species with a 17 recovery plan every 5 years. In theory, these reviews should be able to identify changes in 18 recovery status that fall short of reclassification. In practice, the contents of the reviews are 19 rarely standardized, complicating attempts to objectively track status changes or to compare the 20 status of multiple species. For example, no standardized guidelines exist for assessing population 21 reductions or changes in species extinction risk, as seen in other conservation assessments such 22 as the IUCN Red List (IUCN Standards and Petitions Committee, 2019). Further, even if all 5- 23 year reviews were to adopt standardized content, it is impractical to read the reviews for the over 24 1,660 U.S. listed species every 5 years to identify recovery trends (e.g., improving, stable, or 25 declining). 26 27 One solution is for the Services, as part of every 5-year review, to specify species status changes 28 in a concise, standardized manner. This information would allow the agencies to track changes 29 more reliably and to efficiently compare changes across hundreds of species, similar to how a 30 stock index allows for rapid comparison across hundreds of companies. When this species status 31 information is combined with data on species funding, habitat and threat assessments, local and 32 regional administrative variation, and conservation interventions, a fuller picture emerges with 33 greater resolution of the factors affecting species improvement or decline. 34 35 To examine the feasibility this approach, we worked with the USFWS to develop and test novel 36 metrics to track changes in species recovery status. These metrics are designed to concisely 37 reflect the most important information in a 5-year review about how a species’ status has 38 changed since the prior review. Over 75 biologists from five organizations representing 39 government, academia, and nonprofit groups tested the metrics on 50 ESA-listed species: 4 fish, 40 6 herpetofauna, 6 mammals, 8 birds, 4 insects, 1 arachnid, 5 crustacean, and 16 vascular plants 41 (Figure 1). Species were not selected randomly, but rather for taxonomic and geographic 42 diversity, and for recentness of a 5-year review to ensure that our testing covered a variety of 43 species and used updated information. This effort represents the largest number of scientists to 44 have evaluated the recovery status of a group of ESA-listed species using the same metrics. The 45 USFWS is currently considering whether and how to adopt the metrics. 46 4 Page 6 of 23 1 In this paper, we summarize the results of our assessment of the metrics and describe major 2 challenges to recovery that we identified during testing and offer recommendations to address 3 them. These challenges and recommendations, based on the 50 test species and our combined 4 experience, apply broadly to a large number of other ESA species. We urge federal agencies to 5 consider these recommendations as part of their efforts to conserve species and restore the role of 6 science (Executive Order No. 13,990, 2021). 7 8 The Recovery Metrics 9 At the outset of our project, the USFWS identified three criteria for evaluating the success of the 10 metrics: 1) metrics capture the critical components of tracking species recovery progress; 2) 11 metrics generate consistent results irrespective of the person applying them; and 3) USFWS 12 biologists can apply the metrics easily and without a significant time commitment. Thus, the 13 metrics must strike a balance between comprehensiveness, reliability, and concision. Based on 14 these criteria, we developed six components to assess changes in species recovery status: 15 1. Species’ current levelsFor of resiliency, Peer redundancy, Review and representation (“3Rs”) (Shaffer & 16 Stein, 2000; Figure 2).
