Overland spread of aquatic invasive species among freshwater ecosystems due to recreational boating in Canada / Drake, D. Andrew R.: Fs70-5/2017-031E-PDF

“A literature review was conducted to summarize the overland spread of aquatic invasive species (AIS) among freshwater ecosystems due to recreational boating in Canada. Based on a review of 57 primary publications, factors contributing to overland spread involved heterogeneity in individual boater behaviour, such as differences in trip-taking frequency, the timing between trips, and the spatial distribution of boating locations relative to source populations of AIS. These factors, in addition to measures taken by boaters to remove AIS from boats and related equipment (such as picking visible material from anchors or cleaning hulls) dictate the variety, density, and viability of transported AIS between source and recipient ecosystems, ultimately determining the likelihood of overland spread. Therefore, as with other pathways of AIS introduction and spread within Canada, a subset of human-mediated events pose the majority of invasion risk due to context-dependent environmental and behavioural factors"--Abstract, p. iv.
