New Zealand Mudsnail removed from list of riskiest invaders — GLMRIS High–Risk Species List reduced to 39
- Non-Native Species of Concern and Dispersal Risk for the Great Lakes and Mississippi River Interbasin Study 550 KB
The initial publication of the Aquatic Nuisance Species (ANS) White Paper, the first interim product of the Great Lakes and Mississippi River Interbasin Study (GLMRIS), listed 40 High-Risk Species to potentially transfer between the Great Lakes and Mississippi River basins through the Chicago Area Waterway System. A late incorporation of a comment made by the U.S. Fish and Wildlife Service during the secondary agency review reduces the list to 39, as the New Zealand Mudsnail, which is already found in both basins, will be removed.
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 high-risk species will be an initial focus in GLMRIS.
With the removal of the New Zealand Mudsnail from the list, 10 species are high risk for potential transfer to the Great Lakes Basin and 29 are high risk for potential transfer to the Mississippi River Basin.
The identification of the species in the ANS White Paper will aid the GLMRIS Team in focusing efforts toward identifying available prevention and control technologies for further analysis.
The Other Pathways Team (Focus Area 2) will be using the ANS White Paper to develop site-specific High-Risk Species lists for all other potential aquatic pathways along the basin divide.
