Challenges• Community awareness?• Chaotic landownership?• No coordinated monitoring• Who manages what species?• What controls work?• Who cares?
Extension Agent Blues• How to engage the community(ies)?• Political messes and other pitfalls• Who leads?• Stay non-regulatory• Being an advocate when it counts
Picking Battles
• Train for Early Detection• Organize the communities of interest• Look for new allies• Work at appropriate
scales

Response)

Key Stages in Biological Invasions
• No land use focus• No audience• Too few partners• Lacked field-ready
materials• Reporting protocols
still rough
• CoastWatch Volunteers largely
• Too many partners• 1-day was not
enough but too long• Too many taxa,
habitats, spp.• Field-ready materials
a mixed bag• Protocols better
• Park-focused• Audience focused• Good mix of
partners• Only 8 species• Plants only• Right materials• Easy reportinghttp://tiny.cc/ccedin

Community Organizing(AKA herding interests)
Tillamook Soil and Water Conservation District
Solution: organize them!
Lessons Learned from Others
• Formal structure & identity is important*• Build measurable action plan and honor it*• Build state, federal political support**• Quantify economic costs of I. spp.*• Public awareness is key*• Feedback to community important*
* Gunderston-Izurieta, Paulson and Enloe, 2008** Flint, personal communication, 5/20/2009
Tillamook County PRISM• Based on Cooperative Weed Management
Areas• Integrated and cooperative approach• PRISMs expand to address entire range of
taxa. • NY models to follow• First on the West Coast
CWMAs, PRISMS, etc.

Working @ appropriate scales
Working @ Community Scale
• Map the populations• Treat those possible as soon as possible• Plan to re-treat next growing season• Notify landowners in stages depending on
severity of infestation• Assist w. control where + when possible• Provide the best research on control• Deal seriously w. real or imagined fears
