生物入侵的控制取决于跨入侵区的资源管理者的集体决策。我们称之为“管理马赛克”的土地利用多样性高的地区可能会受到严重的入侵，主要原因有两个。首先，随着土地越来越细分，每个管理者承担入侵物种造成的总损害的一小部分;因此，控制入侵物种的动机减少了。其次，管理者选择不控制入侵增加控制成本，为邻近的土地管理者，让他们的土地作为入侵者繁殖源。管理者之间的协调有助于减轻这些影响，但占据一个地区的土地管理者人数多、种类多，阻碍了集体行动。在这里，我们讨论了管理马赛克所带来的挑战，使用的案例研究的黄色星蓟（Centaurea solstitialis）入侵的内华达州山麓的加州。我们建议，将管理镶嵌动态入侵物种的研究和管理是至关重要的成功控制入侵，并提供建议，以满足这一需要。
Control of biological invasions depends on the collective decisions of resource managers across invasion zones. Regions with high land-use diversity, which we refer to as "management mosaics", may be subject to severe invasions, for two main reasons. First, as land becomes increasingly subdivided, each manager assumes responsibility for a smaller portion of the total damages imposed by invasive species; the incentive to control invasives is therefore diminished. Secondly, managers opting not to control the invasion increase control costs for neighboring land managers by allowing their lands to act as an invader propagule source. Coordination among managers can help mitigate these effects, but greater numbers and a wider variety of land managers occupying a region hinder collective action. Here, we discuss the challenges posed by management mosaics, using a case study of the yellow starthistle (Centaurea solstitialis) invasion in the Sierra Nevada foothills of California. We suggest that the incorporation of management mosaic dynamics into invasive species research and management is essential for successful control of invasions, and provide recommendations to address this need.
