Data in support of: AIS Explorer: Intervention Impact - An application for planning cost-effective AIS prevention programs

The movement of aquatic invasive species (AIS) between waterbodies is often facilitated by overland transport on recreational boats. Once established, AIS can have detrimental ecological effects that are difficult or impossible to manage. Prevention is the most cost-effective AIS intervention strategy, with many management agencies focused on implementing spread prevention techniques such as boater education, watercraft inspection, and hot water decontamination. Given resource constraints, deciding which spread prevention techniques to implement and where to place them is a decision fraught with uncertainty. . In this study, we collected data for, developed, and tested, a new application entitled “Intervention Impact” for the AIS Explorer, an online AIS program-planning dashboard (www.aisexplorer.umn.edu). The application assists AIS managers by simulating scenarios derived from user-defined lake-level budgets, effort, and effectiveness of interventions, enabling them to make comparisons. The outputs provide estimates for risk reduction and infestations averted for both zebra mussel and starry stonewort in Minnesota lakes. We demonstrate the utility of this application using the conditions of Cass County, Minnesota, USA as a case study. Our simulation outputs highlight the tradeoffs of each prevention strategy applied given budget constraints and demonstrate that value of a data-driven approach to guide the implementation of cost-effective prevention plans.
