Invasive species management in natural landscapes is generally executed at the scale of independent jurisdictions, yet the ecological processes and biodiversity to be protected from invasion occur over large spatial scales and across multiple jurisdictions. Jurisdictional land boundaries can influence the flows and dynamics of ecological systems, as well as the social systems that exist in these complex landscapes. Land management entities in large, protected area–centered ecosystems may use different approaches to address cross-boundary management challenges. To understand these differing strategies and their effects on cooperative invasive plant management, we interviewed employees with federal, county, and state agencies, research organizations, nonprofits, and local stakeholder groups in two national parks and their surrounding lands in California, USA. Although all participants stressed the importance of working together, they did so along a continuum of strategies ranging from simple communication to coordination of independent efforts to active collaboration. Barriers to collaboration can be categorized as originating within or externally to the management unit, including limited resources, differing agency priorities, paperwork requirements, and lack of support by higher-level managers. Strategies to reduce barriers depend on where they originate.

以保护区为中心的生态系统中的跨境杂草管理：它如何发挥作用，以及是什么使它更难实现？

自然景观中的入侵物种管理通常在独立管辖范围内执行，但要保护免受入侵的生态过程和生物多样性发生在大空间尺度和跨多个管辖范围内。管辖土地边界可以影响生态系统的流动和动态，以及这些复杂景观中存在的社会系统。以保护区为中心的大型生态系统中的土地管理实体可能会使用不同的方法来应对跨境管理挑战。为了了解这些不同的策略及其对合作入侵植物管理的影响，我们采访了联邦、县和州机构、研究组织、非营利组织、和美国加利福尼亚州两个国家公园及其周边土地的当地利益相关者团体。尽管所有参与者都强调了合作的重要性，但他们采取了一系列策略，从简单的沟通到协调独立努力，再到积极合作。协作的障碍可以归类为源自管理单位内部或外部，包括资源有限、机构优先事项不同、文书工作要求以及缺乏更高级别管理人员的支持。减少障碍的策略取决于它们的来源。协作的障碍可以归类为源自管理单位内部或外部，包括资源有限、机构优先事项不同、文书工作要求以及缺乏更高级别管理人员的支持。减少障碍的策略取决于它们的来源。协作的障碍可以归类为源自管理单位内部或外部，包括资源有限、机构优先事项不同、文书工作要求以及缺乏更高级别管理人员的支持。减少障碍的策略取决于它们的来源。
