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

Why Monitor Non-native Aquatic Invasive Species?
They’re a problem!

Why Monitor Non-native Aquatic Invasive Species?
We have lots of questions

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

Why Monitor Non-native Aquatic Invasive Species?
Because the law says to!
Nonindigenous Aquatic Nuisance Prevention and Control Act of 1990

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
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
