Recent research highlights the challenge of achieving environmental governance goals in the absence of collaboration among interdependent policy actors. This article explores factors contributing to the likelihood of “collaboration gaps” among actors who are interdependent because their jurisdictions overlap. Analysis of data on collaboration among organizations involved in wildfire risk governance in Oregon indicates that interdependent actors are more likely to collaborate. Despite this tendency, nearly 75 % of possible collaborations between interdependent actors were absent. In turn, these collaboration gaps tended to be brokered by third-party actors, especially those lacking the authority to manage land themselves and those for whom the benefits of brokerage may be more immediately apparent. Taken together, these findings shed light on actors’ strategies for navigating fragmented governance systems and highlight opportunities to improve risk mitigation outcomes by enabling greater coordination among interdependent actors.

最近的研究强调了在相互依赖的政策参与者之间缺乏合作的情况下实现环境治理目标的挑战。本文探讨了导致相互依赖的参与者之间“合作差距”可能性的因素，因为他们的管辖范围重叠。对俄勒冈州参与野火风险治理的组织之间协作的数据分析表明，相互依赖的参与者更有可能进行协作。尽管有这种趋势，但相互依存的参与者之间近 75% 的可能合作并不存在。反过来，这些合作差距往往是由第三方参与者促成的，尤其是那些没有权力自行管理土地的人和那些中介的好处可能更明显的人。综合起来，
