Samenvatting
Since 1959, the St. Lawrence Seaway has provided a route into the Great Lakes not only for trade, but also for aquatic invasive species (AIS), which have had severe economic and environmental impacts. A committee convened by the National Research Council through the Transportation Research Board and the Division on Earth and Life Studies recommends that trade continue on the St. Lawrence Seaway but with a suite of AIS prevention measures that evolves in response to lessons learned and to new technologies. Thisfinding is reported in TRB Special Report 291, "Great Lakes Shipping, Trade, and Aquatic Invasive Species." Highlights of TRB Special Report 291 are discussed in this article.
