Human disturbance to beach-nesting birds presents complex challenges to land managers on the U.S. Gulf Coast, which traditional stewardship strategies may be unable to adequately address on their own. Community-Based Social Marketing (CBSM) is a 5-step behavior-change framework that can increase the efficacy of traditional stewardship practices using tailored social science and marketing methods. This iterative process involves 1) selecting target behaviors for behavior-change campaigns, 2) determining constraints, benefits, and norms surrounding target behaviors, 3) designing and 4) implementing campaigns, and 5) evaluating campaign effectiveness. CBSM lends itself well to co-production, a process wherein researchers and practitioners work together throughout research and implementation procedures, due to CBSM having research and implementation components integrated into a single process. In our work, Virginia Tech’s Dayer Human Dimensions Lab served as social science researchers, while shorebird biologists from National Audubon Society and its affiliates acted as implementers in a CBSM project to reduce human disturbance on coastal beaches in Alabama, Mississippi, and Louisiana. Our team worked together to define target disturbance behaviors and campaign sites using initial human behavior and bird monitoring data. The Dayer Lab then conducted interviews and surveys of beach recreationists, incorporating feedback on design and interpretation from implementers, to establish the human behavioral context of campaigns. Implementers were then supported by Dayer Lab researchers in the design and integration of behavior change strategies into tailored CBSM campaigns, followed by social and ecological monitoring and evaluation campaign efficacy as campaigns were implemented. The work presented demonstrates how a co-production process can be leveraged to produce conservation-focused CBSM campaigns.
