Conservation interventions to reduce vessel strikes on sea turtles: A case study in Florida

Sea turtles and boating activities often occur in shared waters. This is problematic because sea turtles are susceptible to vessel strikes since they spend significant portions of their lives in nearshore shallow water to breathe, reproduce, and feed. Targeted conservation strategies are needed to reduce vessel strikes on sea turtles, and successful integration of stakeholder perspectives is necessary for conservation success. Here, we present results from a multi-step approach to investigate responses to potential conservation interventions for reducing vessel strikes on sea turtles. First, challenges and opportunities related to potential interventions that could be used to reduce sea turtle vessel strikes were discussed and assessed by a workshop of conservation and enforcement experts. Second, the workshop-identified interventions were incorporated into a survey questionnaire for recreational boaters. Third, this face-to-face survey was administered around the St. Lucie Inlet, an area identified as a vessel strike hot spot in Florida (USA). The questionnaire asked about boating preferences and practices, existing and potential conservation interventions, and sea turtle presence in the area. Respondents suggested that greater community support for implementation of interventions would be obtained if they (1) were voluntary rather than mandatory/legislated, (2) overlapped with existing interventions (e.g., if speed mitigation zones for sea turtles overlapped significantly with existing speed reduction zones for manatees) and/or added minimal new restrictions and inconveniences, and (3) were accompanied by explanatory materials on the need for, and the effectiveness of, such management strategies. Boater buy-in for management strategies and compliance can vary significantly. As such, our exploratory study should be replicated where proposed sea turtle conservation-related strategies might be warranted to ensure proper contextual fit. Boaters are a powerful, integral, and a growing demographic that must be effectively and respectfully engaged for effective sea turtle conservation in Florida and beyond.

Automated summary

Conservation strategies are needed to reduce vessel strikes on sea turtles, with stakeholder perspectives being crucial for success. Results from a multi-step approach suggest that community support is more likely if interventions are voluntary, overlap with existing measures, and are accompanied by explanatory materials. Boater buy-in and compliance vary, highlighting the need to engage this demographic effectively for successful sea turtle conservation.
