Notice of availability.


EPA is announcing the availability of a final report titled, “Predicting Future Introductions of Nonindigenous Species to the Great Lakes” (EPA/600/R-08/066F). The report was prepared by the National Center for Environmental Assessment (NCEA), within EPA's Office of Research and Development (ORD). The Great Lakes of the United States have been subjected to adverse ecological and economic impacts from introduced species. Ballast water discharge from commercial shipping is the major means by which these nonindigenous species have entered the Great Lakes. This assessment demonstrates that successful invasions are best predicted by knowing the propagule pressure (i.e., the number of larvae/individuals entering a new area) and habitat matching (i.e., how similar is the invaded area to the native range of the species). The purpose of the report is to help resource managers focus monitoring activities on particular nonindigenous species at ports that are most at risk of invasion.


This document will be available on or about January 5, 2009.
