Maintaining connectivity between high-elevation public lands is important for wolverines and other species of conservation concern. This work represents the first effort to prioritize wolverine connectivity under future climate conditions using a systematic conservation planning framework. We optimized 10, 15, 20, and 50% of habitat features for wolverines using integer linear programming. We identified 369 privately owned areas in the 10% solution, 572 in the 15% solution, 822 in the 20% solution, and 3,996 in the 50% solution where voluntary landowner easements would improve the long-term landscape functionality for wolverine connectivity. The median estimated easements ranged from $8,762 to $12,220 across the four solutions (total costs $14,874,371 to $196,346,714). Overall, this effort demonstrates the utility of optimization problems for conserving connectivity, provides a proactive tool to engage potential collaborators, identifies easements that will likely protect various subalpine species, and offers a framework for the conservation of additional species.
维持高海拔公共土地之间的连通性对貂熊及其他受保护物种至关重要。这项工作是首次运用系统保护规划框架，在未来气候条件下对貂熊的连通性进行优先排序。我们使用整数线性规划，针对貂熊优化了10%、15%、20%和50%的栖息地特征。在10%的方案中，我们确定了369个私有区域；15%的方案中有572个；20%的方案中有822个；50%的方案中有3996个。在这些区域，自愿的土地所有者地役权将改善貂熊连通性的长期景观功能。在这四个方案中，预计地役权的中位数在8762美元至12220美元之间（总成本在14874371美元至196346714美元之间）。总体而言，这项工作展示了优化问题在保护连通性方面的效用，提供了一个积极主动的工具来吸引潜在合作者，确定了可能保护各种亚高山物种的地役权，并为保护其他物种提供了一个框架。
