  1. Aquatic Weed Eradication Programs: State and Federal Issues Patrick Akers and Robert Leavitt Workshop to Develop Research Priorities December 12, 2005

  2. Issues Preview • Social, Political, Regulatory • Funding consistency • Increased costs, increased delays • Example situation: spongeplant in Shasta Co. • Technical • Flowing water infestations • More detection. Better methods? • Balance between control work, detection, education?

  3. Social, Political, Regulatory Issues • Funding consistency vs need for persistent effort • Increased costs, increased delays, leading to decreased capabilities • Multiple overseers • Example situation: spongeplant in Shasta Co.

  4. Technical Issues • How do we control hydrilla in flowing water systems, particularly if copper use is severely restricted ? How would we control fragments? • What if we detected fluridone resistant hydrilla in California, what would we use to control it?

  5. Technical Issues • Are there ways to protect non-target (eg T&E) plants from exposure while still using flouridone? Eg, Sidalcea in creek below Nevada fairgrounds pond.

  6. Technical Issues • Are there more efficient methods to search for tubers? • How do you detect one plant in 1,000s of surface acres? • How long should we continue to search for that one plant?

  7. General Concerns • What would we do if we detected hydrilla in the Sacramento-San Joaquin Delta? Can Egeria be used as a model system? • Should we be evaluating new methods of control? Are there any newly emerging possibilities?

  8. General Concerns • Is there a good balance between detection, control work, and public education? Is there a way to determine when you have such a balance? We have been focusing heavily on control and meeting regulatory requirements in the last few years.

  9. Conclusion • Thanks for your ideas.
