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?

Why Monitor Non-native Aquatic Invasive Species?

• Theyre a problem!
• Hundreds of nonnative species in the Pacific
  Northwest
• Threat to native species
• Nationally billions of dollars

Why Monitor Non-native Aquatic Invasive Species?

• We have lots of questions
• Distribution and abundance
• Pathways of introduction
• Impacts
• Effectiveness of management programs

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

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

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

16
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
