ABSTRACT: The “Aquatic Invasive Species Passage Project Screening Tool” is designed to support U.S. Fish & Wildlife Service (FWS) personnel in their evaluation and ranking of proposed fish passage and stream restoration projects, specifically with respect to the potential to spread of aquatic invasive species (AIS). This Microsoft Excel-based, decision-support tool was developed for use in project planning by FWS personnel within the Upper Mississippi, Ohio River, and Lower Missouri River Basins. The tool focuses on potential passage removal projects that could promote hydrologic connectivity, specifically in areas where the potential range expansion of fish and crustacean AIS through aquatic pathways should be considered as part of the barrier removal decision process. In order to provide scientifically supported advice, the tool was created through a review of existing, relevant protocols, studies, risk assessments, reports, and regulations that support decision making on passage projects. This literature review included compiling relevant life history and habitat preference information for 10 AIS threats found within the project region and the selection of key metrics to be included in the tool. The concept tool is designed for the following aquatic invasive species: bighead carp, silver carp, black carp, scud, northern snakehead, rusty crayfish, round goby, inland silverside, white perch, and Eurasian ruffe. The tool is also simple and flexible enough to accommodate additional species and updated information, when available. The AIS expansion risk for a potential project is scored by working through a series of metrics and questions, with a pre-defined scoring system that automatically calculates the overall risk score for the project. This talk will discuss the background and process that went into developing the tool and the overall functionality of the tool in supporting passage project decisions.
