入侵物种管理的主要目标是消除或减少入侵物种的数量。虽然管理工作的动机往往是更广泛的目标，如减少入侵物种对生态系统和社会的负面影响，但很少评估基于人口的（例如，移除入侵者）和更广泛的目标（例如，生态系统的恢复），用于入侵物种管理。为了解决这个问题，我们进行了一个全面的审查研究（N = 151），去除入侵物种，并评估随着时间的推移生态恢复。在大多数情况下，我们发现了积极或混合的结果，但31%的时间生态恢复没有发生或有负面的生态结果，如非目标入侵物种的增加。在人为干扰相对较少和其他入侵者较少的地区，以及与植物群落和生态系统过程相比，动物种群和群落的恢复更有可能实现生态恢复。管理方案的要素，如入侵者是否被根除（完全清除）与积极抑制（≥90%清除），并不影响生态恢复的可能性。我们的研究结果强调了在设计和实施入侵物种管理计划时考虑更广泛目标和意外结果的重要性。
The primary goal of invasive species management is to eliminate or reduce populations of invasive species. Although management efforts are often motivated by broader goals such as to reduce the negative impacts of invasive species on ecosystems and society, there has been little assessment of the consistency between population-based (e.g., removing invaders) and broader goals (e.g., recovery of ecological systems) for invasive species management. To address this, we conducted a comprehensive review of studies (N = 151) that removed invasive species and assessed ecological recovery over time. We found positive or mixed outcomes in most cases, but 31% of the time ecological recovery did not occur or there were negative ecological outcomes, such as increases in non-target invasive species. Ecological recovery was more likely in areas with relatively little anthropogenic disturbance and few other invaders, and for the recovery of animal populations and communities compared to plant communities and ecosystem processes. Elements of management protocols, such as whether invaders were eradicated (completely removed) versus aggressively suppressed (≥90% removed), did not affect the likelihood of ecological recovery. Our findings highlight the importance of considering broader goals and unintended outcomes when designing and implementing invasive species management programs.
