2019 Update To "An Impact Assessment Of Great Lakes Aquatic Nonindigenous Species"

This report includes all major updates to the earlier Risk Assessments on nonindigenous species conducted by the GLANSIS project during the 2019 calendar year. All new assessments were conducted following the same methods outlined in the original technical memorandum, NOAA Technical Memorandum GLERL-161 “An impact assessment of Great Lakes aquatic nonindigenous species” (Sturtevant et al, 2014). All re-assessments are based on new literature surveys using the original as a baseline and conducted to the same methods. All assessments were reviewed by members of the GLANSIS Team (according to expertise) and by select external reviewers. Results of each risk assessment are incorporated into the species profiles found on the GLANSIS website (www.glerl.noaa.gov/glansis/). Grant no. NA17OAR4320152
