  1. Planning for WEED CONTROL Aquatic Plant Management and Protection Aquarius Systems’ Aquatic Plant Harvesting Seminar Dan Helsel, Wisconsin DNR

  2. Tell’ya what I’m gonna to tell’ya Tell’ya Tell’ya what I told’ya

  3. Presentation Outline • Why Plan • Setting Goals and Objectives • Collecting the Right Information • Identifying the Management Intensity • Choosing the Management Tool • Monitoring and Assessment

  4. Why Plan? • Formulates a proactive strategy rather then a reactive attack • Anticipates the time and money • Develops a critical pathway • Publicizes expectations

  5. Plan Components • Goals & Objectives • Lake Information • Management Intensity • Management Method • Monitoring & Assessment • Education • Business Aspects

  6. Monitoring & Evaluation Management Methods Management Location and Intensity Lake Information Goals and Objectives

  7. Goals and Objectives • Goals • Broadly lists your desired accomplishments • Objectives • List specific tasks that need to be completed to achieve your goal

  8. Typical APMP Goals • Reduce the amount of nuisance aquatic plant growth in high use recreational areas

  9. Typical APMP Goals • Protect and promote the expansion of diverse, native aquatic plant areas

  10. Typical APMP Goals • Educate and inform lake residents about APMP activities

  11. Typical APMP Goals • Reduce or prevent the introduction of nuisance exotic species

  12. Example • Goal • Protect aquatic plants in valuable sensitive areas • Objectives • Map sensitive areas • Design management to protect area • Educate lake residents

  13. The APMP Plan Does This Goals & Objectives • Should Not: • Specify the specific management strategy • Specify the management intensity • Specify the specific areas for management • Specify which consultant or manufacturer

  14. Physical Characteristics Recreation and Aesthetics Fish & Wildlife Community Aquatic Plant Community Lake Information

  15. Physical Characteristics Delineate: • Navigational Hazards • Shallows (< 3 ft) • Littoral growth zones (3< >15 ft) • Deep zones (> 15 ft)

  16. Aquatic Plant Community Delineate: • Nuisance exotic species • Mixed nuisance growth • Healthy aquatic community • Restoration areas

  17. Aquatic Life Community Delineate: • Critical areas • Outstanding areas • Fair areas • Minor areas • Degraded areas

  18. Recreation & Aesthetics Delineate: • Intense recreation • Moderate recreation • Near-shore riparian use • Resource based use

  19. Identifying Management Intensity Overlay Maps to Delineate Areas of Different Management Intensity

  20. Identifying Management Intensity • ProhibitedManagement • Selective Management • Nuisance Relief • No Restrictions • Restoration

  21. Chemical Selective Contact Mechanical Manual Harvesting Dredging Biological Weevil Physical Drawdown Bottom Barriers Management Methods Generally Used in WI

  22. Which Method? There is no silver bullet that will solve your nuisance aquatic plant problem

  23. Advantages Immediate Relief No use of toxic chemicals No water use restrictions Can be selective Removal of plant material Leaves bottom plants for stabilization Limitations Disposal/off loading sites required Higher maintenance and labor costs Relatively slow Disturbs sediments in shallow waters Takes aquatic life Contracting not readily available Mechanical Harvesting

  24. Monitoring & Assessment • Critical to evaluate effectiveness and efficiency • Requirements • Quantitative information • Comparative from year to year • Objective • Presented to lake users • Feedback for plan modifications

  25. Information and Education • Very Important • Stay Awake for Charlie’s Talk

  26. Business Plan • Describe human health and safety issues • Describe potential property damage • Address liability • Environmental risks • Cost

  27. Where to go for answers? • Lake Line Issues • Aquatic Chemical Use (May 1997) • Biological Control (September 1997) • Mechanical Harvesting (March 1998) • Plant Restoration (March 1999) • Planning (Spring 2000)

  28. Where to go for more harvesting answers? • Your Aquatic Harvesting Program (WDNR 1997) • Journal of Aquatic Plant Management • University of Florida Aquatic Plant web page

  29. Where to go for the CORRECT answers? Charile ShongPewaukee Lake • Glen KreinbrinkBeulah Lake • Kevin MacKinnonDelavan Lake • And others from WAL & NALMS Dan & Scott
