IISG’s Pat Charlebois and Sarah Zack were members of a committee on recreational water use, and Pat co-chaired a committee on water garden guidelines, both aimed at preventing the spread of aquatic invasive species (AIS) through these two pathways. The committees recently completed their report, Voluntary Guidelines to Prevent the Introduction and Spread of Aquatic Invasive Species; Recreational Activities and Water Gardening, which provides guidelines for recreational water users and water gardeners to follow. 
 
The steps listed include cleaning, draining, and drying all recreational equipment (boats, vests, trailers, etc.) following a day on the water (for recreational water users), and purchasing/planting native plants or properly disposing of unwanted specimens (for water gardeners). 
 

There are more simple steps outlined in the two documents that can help prevent the spread of invasive species through these two pathways, as well as information about the importance of protecting waterways and native ecosystems. Visit the links above to read the complete reports, and visit our “Be A Hero – Transport Zero” and “Stop Aquatic Hitchhikers” webpages for additional information. 

*Note: This post originally listed Pat Charlebois as a co-chair of the recreational water users committee and omitted Sarah Zack’s participation. The text has been corrected.
