The Endangered Species Act (ESA) provides legal protection to imperiled populations and their associated habitats. As a part of this process, listed species must undergo a general status review (also called 5‐Year Review) to assess the progress toward recovery every 5 years. However, almost all 5‐year reviews result in a status of “no change,” prompting scientists to question if the review process is robust enough to detect changes in recovery. The U.S. Fish and Wildlife Service (USFWS) was therefore interested in developing a standardized metric for monitoring more nuanced recovery progress as part of the status review. In collaboration with the USFWS, over 75 biologists from five different organizations developed and tested a set of novel metrics to summarize recovery progress of listed species by considering current and future conditions, threats, and conservation measures. We found that, although the majority of species had reviews with a recommendation of no change, scorers were able to use the metrics to interpret more nuanced changes in the 3Rs (resiliency, redundancy, and representation), threats, and conservation measures than in the status review. Our results suggest that these metrics could illuminate more nuanced areas of recovery and decline in species' conditions, but consistency among scorers and status reports should be a focus of future development. Our approach offers a rigorous set of metrics to systematically track the recovery progress of all ESA species.
