Date of data collection: June-August 2022 5. Geographic location of data collection (where was data collected?): at public water accesses in 14 Minnesotan counties (Hennepin, Ramsey, Todd, Washington, Chisago, Itasca, Carlton, St. Louis, Lake, Crow Wing, Stearns, Anoka, Dakota, Goodhue) and 1 Wisconsin county (Douglas) 6. Information about funding sources that supported the collection of the data: Minnesota Aquatic Invasive Species Reserach Center (MAISRC); United States Geological Survey (USGS), National Institutes for Water Resources (NIWR); UMN Water Resources Center (WRC); Environment and Natural Resources Trust Fund (ENRTF) 7. Overview of the data (abstract): Efforts to prevent the spread of aquatic invasive species (AIS) have been widely implemented at many scales to mitigate economic and environmental harms. Boater education, watercraft inspection, and hot water decontamination are popular strategies for prevention of AIS moving through the recreational boating pathway. However, few studies have actually quantified the effectiveness of these strategies under field conditions. We estimated their effectiveness based on the performances of boaters, watercraft inspectors, and hot water decontaminators. Participants (n=144) were recruited at 56 public water access sites in Minnesota and 1 in Wisconsin. Each participant was asked to inspect and remove AIS from a boat staged with macrophytes, dead zebra mussels, and spiny water fleas. The types and amounts of AIS removed were used to estimate the effectiveness of each prevention method. We observed that removal varied by type of AIS, with macrophytes being most commonly removed for all participants. There were also regional (metro and outstate) differences for some species perhaps due to awareness and education. Hot water decontamination was the most effective (83.7%) intervention but was not significantly better at reducing risk of spread than was watercraft inspection (79.2%). Boaters were less effective at AIS removal (56.4%). Our results suggest that watercraft inspection is an effective prevention method for most boats, and that hot water decontamination is an important tool for high-risk boats. However, robust decontamination protocols are difficult to effectively execute. Furthermore, our results provide insights into how to increase boater awareness of often-overlooked locations and help reduce risk when inspectors cannot be present at a public water access site. -------------------------- SHARING/ACCESS INFORMATION -------------------------- 1.

Description of methods used for collection/generation of data: Please see Angell et al. 2023 for a complete description of methods 2. Methods for processing the data: Raw data determining effectiveness for the AIS removal process were collected via paper and pen (except for the surveys which were via qualtrics/tablet) and transfered to .xlsx files and then .csv files. Data on hot water decontamination effectiveness were obtained with a thermal imager (FLIR E75 Thermal Imager) and analyzed using the manufactures software (FLIR Thermal Studio Standard Version). 3. Instrument- or software-specific information needed to interpret the data: The data were interpreted in RStudio version 4.1.3. and FLIR Thermal Studio Standard Version. 4. Standards and calibration information, if appropriate: For examining thermal imagery data to determine hot water decontamination effectiveness a standard threshold of 60 degress celcius for 10 seconds was used to determine section sufficiency for boat sections 1-39 and a threshold of 48.89 degress celsius for 130 seconds was used for seciton 40. 5. Environmental/experimental conditions: Experiments occured at public water access sites in Minnesota and Wisconsin in the summer months of June to August when weather was permitable. 6. People involved with sample collection, processing, analysis and/or submission: John Gierretson was a technician that helped to prepare the boat for the experimental AIS removal process and also collect the data pertaining to the "PARTICIPANT_ACTIONS.csv" ----------------------------------------- DATA-SPECIFIC INFORMATION FOR: inspection_and_decon_removal.csv ----------------------------------------- 1.
