Endangered Species Act recovery plans must meet legal requirements (1) to provide recovery time and cost estimates, (2) to set objective and measurable delisting criteria, and (3) to address the five factors that are considered when listing or delisting a species. These five factors include: threats to habitat or range, whether or not a species is subject to overutilization, presence of disease, existence of regulatory mechanisms outside of federal protection (i.e., the states), and if there are other natural or anthropogenic factors impacting continued existence. We reviewed recovery plans for fish listed under the Endangered Species Act and managed by the Fish and Wildlife Service (USFWS) to determine how many meet these requirements. Of 105 recovery plans for fish taxa managed by the USFWS, 52% of plans estimated time to recovery, 44% plans estimated cost of recovery, and 61% plans provided quantitative recovery criteria. Only one-third of these recovery plans specifically addressed the five delisting factors, which include taxa-specific threats to species persistence. The USFWS is using the species status assessment (SSA) framework to inform species management, with 15 listed species that have a completed SSA. As SSAs are completed to inform objective and measurable criteria, recovery plans could be revised or amended at the time of 5-year reviews, especially for taxa whose time and cost estimates for recovery have been surpassed.

美国鱼类和野生动物管理局管理的受威胁和濒危鱼类分类的恢复计划标准审查

《濒危物种法案》恢复计划必须符合法律要求(1)提供恢复时间和成本估算,(2)设定客观和可衡量的除名标准,以及(3)解决在列出或除名物种时考虑的五个因素。这五个因素包括:对栖息地或范围的威胁,一个物种是否受到过度利用,是否存在疾病,是否存在联邦保护之外的监管机制(即各州),以及是否有其他自然或人为因素影响继续存在。我们审查了根据《濒危物种法》列出并由鱼类和野生动物管理局 (USFWS) 管理的鱼类的恢复计划,以确定有多少鱼符合这些要求。在 USFWS 管理的 105 个鱼类分类群恢复计划中,52% 的计划估计恢复时间,44% 计划估计回收成本,61% 计划提供量化回收标准。这些恢复计划中只有三分之一专门针对五个退市因素,其中包括对物种持久性的特定分类威胁。USFWS 正在使用物种状态评估 (SSA) 框架来为物种管理提供信息,其中列出的 15 个物种具有完整的 SSA。由于完成了 SSA 以提供客观和可衡量的标准,因此可以在 5 年审查时修订或修订恢复计划,特别是对于已超过恢复时间和成本估计的分类群。USFWS 正在使用物种状态评估 (SSA) 框架来为物种管理提供信息,其中列出的 15 个物种具有完整的 SSA。由于完成了 SSA 以提供客观和可衡量的标准,因此可以在 5 年审查时修订或修订恢复计划,特别是对于已超过恢复时间和成本估计的分类群。USFWS 正在使用物种状态评估 (SSA) 框架来为物种管理提供信息,其中列出的 15 个物种具有完整的 SSA。由于完成了 SSA 以提供客观和可衡量的标准,因此可以在 5 年审查时修订或修订恢复计划,特别是对于已超过恢复时间和成本估计的分类群。
