Abstract

Human-bear conflict is increasingly driven by the expansion of human development into bear habitat and the availability of unsecured anthropogenic attractants. Although attractant securement is widely recognized as one of the most effective strategies for reducing conflicts, implementation remains uneven across communities and individual landowners. Communities differ in ecological conditions, attractant diversity, and resource constraints, making it difficult to determine which mitigation actions to prioritize. At the same time, individuals often manage multiple attractants on their property and make decisions of which to secure, when to act, and how to interpret risk within a broader social context. This thesis examines attractant management as a multi-level prioritization problem operating at both community and household scales. First, we used structured decision-making to evaluate and prioritize attractants based on their contribution to conflict risk, cost, and feasibility, using expert elicitation and a portfolio-based approach. Second, we conducted semi-structured interviews with landowners in Montana’s Bitterroot Valley to investigate how risk perception, reference groups, and lived experience shape individual securement decisions. Together, these findings advance understanding of how attractant management operates across scales in communities facing human-bear conflicts.
