Aquatic Nuisance Species

The US Army Corps of Engineers in collaboration with our study partners have published the Aquatic Nuisance Species (ANS) White Paper: Non-Native Species of Concern and Dispersal Risk for the Great Lakes and Mississippi River Interbasin Study. The purpose of the ANS White Paper is to catalog potential non-native species within the Great Lakes and Mississippi River basins and identify which ANS of concern will be an initial focus in GLMRIS.

	ANS of Concern to Each Basin

Thirty-nine (39) aquatic nuisance species are identified in the ANS White Paper as ANS of Concern for GLMRIS Focus Area I (CAWS): 10 are of concern to the Great Lakes Basin and 29 are of concern to the Mississippi River Basin. Explore the 39 Focus Area I ANS of Concern in the tables below.

Compiling this list is the first step in establishing the current and future without project conditions for GLMRIS and will aid the study team in focusing efforts toward identifying potential ANS Controls for further evaluation. The Other Pathways Team (Focus Area II) will be using the ANS White Paper to develop site-specific ANS of concern lists for all other potential aquatic pathways along the basin divide.
