Planning for WEED CONTROL Aquatic Plant Management and Protection Aquarius Systems’ Aquatic Plant Harvesting Seminar Dan Helsel, Wisconsin DNR
Tell’ya what I’m gonna to tell’ya Tell’ya Tell’ya what I told’ya
Presentation Outline • Why Plan • Setting Goals and Objectives • Collecting the Right Information • Identifying the Management Intensity • Choosing the Management Tool • Monitoring and Assessment
Why Plan? • Formulates a proactive strategy rather then a reactive attack • Anticipates the time and money • Develops a critical pathway • Publicizes expectations
Plan Components • Goals & Objectives • Lake Information • Management Intensity • Management Method • Monitoring & Assessment • Education • Business Aspects
Monitoring & Evaluation Management Methods Management Location and Intensity Lake Information Goals and Objectives
Goals and Objectives • Goals • Broadly lists your desired accomplishments • Objectives • List specific tasks that need to be completed to achieve your goal
Typical APMP Goals • Reduce the amount of nuisance aquatic plant growth in high use recreational areas
Typical APMP Goals • Protect and promote the expansion of diverse, native aquatic plant areas
Typical APMP Goals • Educate and inform lake residents about APMP activities
Typical APMP Goals • Reduce or prevent the introduction of nuisance exotic species
Example • Goal • Protect aquatic plants in valuable sensitive areas • Objectives • Map sensitive areas • Design management to protect area • Educate lake residents
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
Physical Characteristics Recreation and Aesthetics Fish & Wildlife Community Aquatic Plant Community Lake Information
Physical Characteristics Delineate: • Navigational Hazards • Shallows (< 3 ft) • Littoral growth zones (3< >15 ft) • Deep zones (> 15 ft)
Aquatic Plant Community Delineate: • Nuisance exotic species • Mixed nuisance growth • Healthy aquatic community • Restoration areas
Aquatic Life Community Delineate: • Critical areas • Outstanding areas • Fair areas • Minor areas • Degraded areas
Recreation & Aesthetics Delineate: • Intense recreation • Moderate recreation • Near-shore riparian use • Resource based use
Identifying Management Intensity Overlay Maps to Delineate Areas of Different Management Intensity
Identifying Management Intensity • ProhibitedManagement • Selective Management • Nuisance Relief • No Restrictions • Restoration
Chemical Selective Contact Mechanical Manual Harvesting Dredging Biological Weevil Physical Drawdown Bottom Barriers Management Methods Generally Used in WI
Which Method? There is no silver bullet that will solve your nuisance aquatic plant problem
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
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
Information and Education • Very Important • Stay Awake for Charlie’s Talk
Business Plan • Describe human health and safety issues • Describe potential property damage • Address liability • Environmental risks • Cost
