The growing scale of natural hazards highlights the need for models of governance capable of addressing risk across administrative boundaries. However, risk governance systems are often fragmented, decentralized, and sustained by informal linkages among local-level risk mitigation planning processes. Improving resilience to the effects of environmental change requires a better understanding of factors that contribute to these linkages. Using data on the patterns of participation of 10,199 individual stakeholders in 837 community wildfire protection plans (CWPPs) within the western U.S., we document the emergence of a locally clustered but spatially extensive wildfire risk governance network. Our evaluation of factors that contribute to connectivity within this network indicates that risk interdependence (e.g., joint exposure to the same fires) between planning jurisdictions increases the prospects for linkages between planning processes, and that connectivity is also more likely among planning processes that are more proximate and similar to one another. We discuss how our results advance understanding of how changing hazard conditions prompt risk mitigation policy networks to reorganize, which in turn affects risk outcomes at multiple spatial scales.

自然灾害规模的不断扩大凸显了对能够跨行政边界应对风险的治理模式的需求。然而，风险治理系统往往是分散的、分散的，并且通过地方级风险缓解规划流程之间的非正式联系来维持。提高对环境变化影响的抵御能力需要更好地了解促成这些联系的因素。利用美国西部 837 个社区野火保护计划 (CWPP) 中 10,199 个个人利益相关者的参与模式数据，我们记录了局部集群但空间广泛的野火风险治理网络的出现。我们对有助于该网络内连通性的因素的评估表明，风险相互依赖（例如，规划管辖范围之间的共同暴露于同一火灾）增加了规划过程之间联系的前景，而且彼此更接近和相似的规划过程之间也更有可能建立联系。我们讨论我们的结果如何促进对不断变化的灾害条件如何促使风险缓解政策网络重组的理解，这反过来又影响多个空间尺度的风险结果。
