How do we translate research

into
action
i iin the
h water
• How do management, policy, community
needs inform future research needs?
• What impediments and opportunities
exist for action? (research
implementation management co
implementation,
coordination)
• At what scale should we be working?
(Federal, state, county, lake district,
lake)
Define an invasive species
• Outside native range
g
• Established self sustaining populations (e.g.
Hybridizing with natives species)
• Net harm > net benefit ?

Super spreaders: Not all boaters pose the same risk
Protecting the most vulnerable lakes
Vander Zanden et al. 2004. Ecol. Appl. 14: 132-148
How do we integrate strategies:
Super spreaders and vulnerabile lakes
- Spiny water flea (Bythotrephes)
- Average boater travel distance (15 miles)
Great lakes
boat
landings
