By the Numbers: How is Recovery Defined by the US Endangered Species Act?
Nearly 40 years after passage of the US Endangered Species Act, the prospects for listed species remain dim because they are too severely imperiled by the time they receive the act’s protection. Even if threats are abated, the low abundances required for recovery often preclude a high probability of persistence. The lack of sufficient data for setting recovery objectives also remains a barrier....

متن کاملAre Recovery Plans Improving with Practice?
We asked two basic questions about endangered species recovery plans: (1) Have recovery plans improved over the last decade? (2) Are important features of recovery plans biased toward plants or animals? We answer these questions in the context of a large national study aimed at statistically summarizing key features of recovery plans and how those plans use science. In addition, we asked if the...
متن کاملUncertainty in Population Estimates for Endangered Animals and Improving the Recovery Process
United States recovery plans contain biological information for a species listed under the Endangered Species Act and specify recovery criteria to provide basis for species recovery. The objective of our study was to evaluate whether recovery plans provide uncertainty (e.g., variance) with estimates of population size. We reviewed all finalized recovery plans for listed terrestrial vertebrate s...
