Community viability analysis (CVA) has been put forth as an analogue for population viability analysis (PVA), an accepted conservation tool for evaluating species-specific threat and management scenarios. The original proposal recommended that CVAs examine resistance-based questions. PVAs, however, are broadly applicable to multiple types of viability questions, suggesting that the original CVA definition may be too narrow. In the present article, we advance an expanded framework in which CVA includes any analysis assessing the status, threats, or management options of an ecological community. We discuss viability questions that can be investigated with CVA. We group those inquiries into categories of resistance, resilience, and persistence, and provide case studies for each. Finally, we broadly present the steps in a CVA.

社区生存能力分析的扩展框架

社区生存力分析 (CVA) 已作为种群生存力分析 (PVA) 的类似物提出，这是一种公认​​的评估特定物种威胁和管理方案的保护工具。最初的提案建议 CVA 检查基于阻力的问题。然而，PVA 广泛适用于多种类型的生存能力问题，这表明最初的 CVA 定义可能过于狭窄。在本文中，我们提出了一个扩展框架，其中 CVA 包括评估生态群落状态、威胁或管理选项的任何分析。我们讨论了可以用 CVA 调查的可行性问题。我们将这些调查分为阻力、复原力和持久性等类别，并为每个类别提供案例研究。最后，我们广泛地介绍了 CVA 中的步骤。
