  1. Exploratory ForumDetecting the Occurrence and Spread of Nonnative Aquatic Invasive Species – Linkages with Comprehensive Monitoring of Aquatic Systems in the Pacific Northwest

  2. Invasive species detection efforts taking place at various scales But how do these efforts relate to the monitoring of species, habitats, and ecosystems where invasive species are found?

  3. Aquatic Monitoring Invasives Monitoring Articulation of Need Development of Plans Implementation Data & Analyses

  4. Aquatic Monitoring Invasives Monitoring

  5. Why Monitor Non-native Aquatic Invasive Species? They’re a problem! • Hundreds of nonnative species in the Pacific Northwest • Threat to native species • Nationally = billions of dollars

  6. Non-indigenous taxa 771 150 125 100 76 Non-indigenous species 75 50 30 25 10 10 7 3 2 0 Fish Birds Plants Reptiles Mollusks Mammals Amphibians Crustaceans (Sanderson)

  7. Introduced Fish State Species of Concern ESA listed Native Fish (Sanderson) Non-listed Native Fish 125 100 46% 54% 75 60% Numberof fish species 50 25 0 WA OR ID

  8. Why Monitor Non-native Aquatic Invasive Species? We have lots of questions • Distribution and abundance • Pathways of introduction • Impacts • Effectiveness of management programs

  9. Total DDT > Effects Range Median 0.1% Mercury > Effects Range Median 0.1% Total Organic Carbon > 5% Chromium > Effects Range Median Dissolved Oxygen < 5 mg/l Sediment Toxicity Invasive Species > 50% Natives Invasive Species Present RELATIVE RISK: EXTENT OF STRESSORS IN PACIFIC COAST ESTUARIES (Lee and Reusser)

  10. Why Monitor Non-native Aquatic Invasive Species? To find new ones and evaluate the effects of established species • Early detection is key to the success of rapid response • New species continue to arrive • Effects of propagule pressure on ecosystems and communities

  11. Number of Atlantic salmon escaping from Washington and British Columbia fish farms (Phillips)

  12. Why Monitor Non-native Aquatic Invasive Species? Because the law says to! • Nonindigenous Aquatic Nuisance Prevention and Control Act of 1990 • National Invasive Species Act of 1996 • Executive Order #13112

  13. Integrative Efforts NISC . . . ANSTF . . . ICAIS . . . The Natural Resources Monitoring Partnership

  14. Hurdles • Lack of adequate information exchange about aquatic invasives even within organizations • Monitoring programs overburdened, and invasives programs more focused on species than systems • Data systems lacking or incompatible with similar systems • Focus on detection but less emphasis on long-term monitoring

  15. Opportunities • Programs to identify, compare and list data bases, and monitoring protocols • Understanding of need to forge linkages among monitoring and detection programs • Mutual interest in biotic communities, ecosystem properties, global change, imperiled species • Early detection - better developed, more easily integrated • Long term monitoring of trends, project effectiveness, community / ecosystem effects - more problematic, but opportunities great http://www.pnamp.org/web/workgroups/SC/meetings/2006_0613/2006_0613InvasiveForumSynthesisNotes.pdf
