Enhancements in Aquatic Nuisance Species Management for the Great Lakes (2010-2011)

In 2010-2011, Dr. Rochelle Sturtevant from NOAA GLSGN and GLERL presented critical enhancements addressing aquatic nuisance species in the Great Lakes. Key achievements included the identification of 'range expansion' species, a high-priority 'watchlist', and updated impact assessments of various species. The addition of 50 non-technical fact sheets and enhanced bibliographic information aims to empower stakeholders with essential management practices and regulations. The updates emphasize risk assessment tools to mitigate the ecological and socio-economic impacts of various aquatic organisms.

  3. GLRI Enhancements • Addition of ‘range expansion’ species – those native to one portion of the Great Lakes but which are considered invasive to other portions of the basin. LIST COMPLETE and OUT FOR REVIEW. Fact Sheets Summer 2011. • Addition of high priority ‘watchlist’ species – those which have been identified in the literature as high risk for invading and becoming established in the Great Lakes. LIST PUBLISHED on GLANSIS.Fact Sheets Summer 2011. • Updated and consistent 'impact' information, especially potential impacts, better able to risk assessment. FAUNA COMPLETE and OUT FOR REVIEW. Microorganisms and plants summer 2011. • Enhanced bibliographic information. Summer 2011. • Addition of 50 non-technical fact sheets for priority species of public interest. In progress. • Addition of management information — regulations, best management practices and control methodologies – for all the species in the database. Fall 2011-Spring 2012.

  4. New GLANSIS SpeciesComing soon… Phragmitesaustralis (invasive lineages) Procambarusclarkii Red Swamp Crayfish

  5. Range Expansion Species ListDRAFT = 41 species • 4 fish currently included in GLANSIS will be moved to the range expansion list – sea lamprey, alewife, margined madtom, orangespotted sunfish • 14 algae and 5 diseases are also being considered for removal from GLANSIS to the Range Expansion List • 14 additional fish, 1 crayfish, 2 algae, and 1 plant are also being added to the Range Expansion list

  6. Watch List53 species Ballast = 75% Ponto-Caspian = 65%

  7. Organism Impact Assessments(1386 questions)What we DON’T know!

  8. Assessments for 77 species What we DON’T know! For 78% of species, data was insufficient for assessment

  9. Organism Impact AssessmentsWhat we DO know! At least 17% of fauna species show a high environmental impact

  10. Organism Impact AssessmentsWhat we DO know! • Alewife was the only species to be rated high impact on all 3 subassessments • Sea lamprey, zebra mussels, quagga mussels and round goby were rated high for environmental and socioeconomic impact and low for beneficial impact • Mud Bithynia (faucet snail) was rated high for environmental impact, moderate for socio-economic impact and low for beneficial impact • Spiny and fishhook waterfleaswere rated high for environmental impact and low for socio-economic and beneficial impacts • White perch was rated high for environmental and beneficial impacts and moderate for socioeconomic impact • Common carp and rainbow smelt were rated high for environmental and beneficial impacts and unknown for socioeconomic impact • Rainbow trout and brown trout were rated high for environmental and beneficial impacts and low for socioeconomic impact

  11. Organism Impact AssessmentWhat we DO know! • Chinook and coho salmon were rated high for benefit, moderate for environmental impact and low for socioeconomic impact • Only two species – suckermouth minnow and green floater – were confirmed as low impact on all three subassessments • Redear sunfish were rated moderate for environmental impacts and benefits and low for socioeconomic impacts.
