Michigan’s Aquatic Invasive Species Program and Wetlands
Decontamination, BMPs, and Prioritization

Coastal Wetlands
Great Lakes are extremely productive, and rare systems are critical to Michigan’s fish, wildlife, and migratory birds.
32 of 36 species of Great Lakes fish
depend upon coastal marshes for reproductive
success.
The vegetation of coastal marshes anchors sands of the beaches during high water periods, providing the most effective protection possible from the erosive impacts of the waves and ice of the Great Lakes.
At least 41 state listed, threatened, and endangered species of animals depend upon
wetlands at some point in their life cycle.
Michigan has approx. 3,288 miles of great lakes shoreline.
Some examples of Coastal Natural Communities:
Coastal Fen Granite Bedrock Lakeshore Great Lakes Marsh Interdunal Wetland Limestone Lakeshore Cliff
Open Dunes Sand and Gravel Beach Sandstone Cobble Shore Wooded Dune and Swale
Including approximately 275,748 acres of Great
Lakes Coastal Wetlands

Invasive Species Program
A species that is not native and whose
introduction causes, or is likely to cause,
economic or environmental harm
or harm to human health

State of Michigan AIS Team established 2010
AIS State Management Plan
• Goal I: Prevent new introductions of AIS into Michigan waters.
• Goal II: Limit the dispersal of established populations of AIS into uninfested waters of the state.
• Goal III: Develop an early detection and rapid response program to address new AIS invasions.
• Goal IV: Manage and control AIS to lessen the harmful ecological, economic, social and public health impacts resulting from infestation of AIS.
Finalized June, 2013
Prevention by Pathways
o BMPs for AIS in Water Resources permits
o Support local governments by providing
information on AIS BMPs and encouraging
coordination
o Promote BMPs for landowners
o Coordinate with other groups and agencies on
training for contractors, consultants, landscapers,
etc.
Habitat Pathway – Strategic Actions
Habitat Pathway – Strategic Actions
Best Management Practices (BMPs)
Dispose of Bait in the Trash
Do Not Release Fish and Aquatic
Plants
Clean, Drain, Dry
Best Management Practices (BMPs)
• Plan - Visit invasive species free areas first!
• Use one-piece rubber waders and boots – non-felt soled.
• Habit - Inspect your gear/attire between sites.
• If possible, try to avoid working in areas at times when risk is highest – e.g. when plants have gone to seed
• If possible avoid walking through infested areas
Be aware of vectors:
Equipment Land Disturbance Ornamental Ponds Shoreline landscaping Roadsides and Utility Corridors
Best Management Practices (BMPs)
Decontamination
Boots and Waders
Field Gear/Clothing
Vehicles
Decontamination
• Inspect and remove all visible vegetation and soil from clothes and footwear – Use a boot brush and Adhesive Roller in the field – Wash clothes and footwear after use – HIGH RISK: Use a household steamer on footwear
• Rinse and Dry (2-5 days) equipment – Medium Risk: Use a bleach/water solution or Virkon
in spray bottle or sponge – HIGH RISK: Pressurized hot water (140 degrees)
• DEQ drafted a tool to help groups prioritize and allocate limited resources
• GOAL: more consistent and more successful management, statewide
• Reviewed and revised by the AIS Advisory Council, and the AIS Core Team
• Scoring tool that can be used to compare multiple sites
• Not for individual site decisions
• Maximum score of 57
Phragmites Treatment/Management Prioritization Tool
Audience: Land/resource management groups who are working at a local or regional scale (local, regional and state land managers)
• Compare potential treatment sites - rank many sites and focus efforts on the highest priority locations first
• Strategically allocate limited resources ($) • Guidance for watershed groups, land conservancies, cooperative weed
management groups, municipalities, etc.
Phragmites Treatment/Management Prioritization Tool
Three Categories of Criteria:
• Ecological Criteria • Human Values Criteria • Feasibility/Coordination of treatment
Phragmites Treatment/Management Prioritization Tool
Example Sites
Example Site A Higher Likelihood of Success
Less Strain on Resources (funding, personnel, equipment)
Example Site B Lower Likelihood of Success
Greater Strain on Resources (funding personnel, equipment)
Early Detection and Response
