Includes bibliographical references (p. 54-57). “A model-based assessment was conducted to estimate the ecological risk of recreational boating as a pathway for the secondary spread of aquatic invasive species (AIS) in the Great Lakes basin (GLB). Boater-mediated spread was quantified based on the number, type, and spatial distribution of recreational boating trips in the GLB, the infestation of boats with functional groups of fouling AIS (plankton, molluscs, and aquatic macrophytes), and the likelihood that organisms would establish reproducing populations based on demographic factors and transported population sizes. Boater-mediated spread timelines were estimated probabilistically up to a maximum period of ten years, allowing the expected timeline of spread to be compared with baseline estimates of natural dispersal"--Abstract, p. iv.
