Waterfowl Hunters: What You Need to Know about Invasive Species

Help Stop The Spread Of Aquatic Invasive Species During Migratory Bird Hunting Seasons
Original Story: WI DNR
The Wisconsin Department of Natural Resources (DNR) reminds migratory bird hunters that they are essential partners in preventing the spread of aquatic invasive species in hunting areas and Wisconsin’s waterways. The steps hunters take before leaving a boat launch or access point are vital for protecting hunting habitat.
Invasives can hide in some of the most unsuspected places. Mud on your anchor can hide seeds, eggs or the larvae of tiny species, such as spiny water fleas. Water that collects in boats and decoys can carry diseases, and insects, snails and seeds can also collect under the vests of a hunting dog. Consider giving your dog a rinse with a jug of clean water or scrubbing them off with a brush while they go for a quick swim to prevent invasive species from hitching a ride to the next hunting spot.
Of particular concern to hunters is the Faucet snail. These snails carry parasites that can kill ducks if they eat them. Learn more about how hunters can help prevent the spread of invasive species and minimize these risks on the DNR’s Invasive Species Prevention webpage or by visiting the “Hunter Resources” tab on the Waterfowl Hunting webpage.
Members of Wisconsin’s Aquatic Invasive Species Partnership may be available in your area to provide presentations and other outreach for hunt clubs and other organizations. They and your Regional DNR Aquatic Invasive Species Biologist can answer specific questions about any aquatic invasive species where you plan to hunt.
Find your county Aquatic Invasive Species contact on the DNR’s website. Many of these folks will visit boat launches during the hunting season to provide on-the-spot education, boat towels and boot brushes. 
Just a few minutes of preventative action can protect our hunting tradition for generations to come. Before launching into and leaving a water body, hunters should:
- Inspect waders, boats, trailers, motors and hunting equipment, including boots, blinds and dogs, before leaving a boat launch or access point.
- Remove all plants, animals and mud to the best of your ability. A special consideration for waterfowl hunters is to remove all seed heads and roots when using vegetation to conceal duck blinds. It is also important to note that it is illegal to use phragmites for camouflage in counties where the plant is prohibited by NR40. In general, these counties include the western half of the state.
- Drain all water from decoys, boats, motors and other hunting equipment.
- Never move plants or live fish away from a water body.

The Fox-Wolf Watershed Alliance is an independent nonprofit organization that identifies and advocates effective policies and actions that protect, restore, and sustain water resources in the Fox-Wolf River Basin.
Reporting invasive species is a first step in containing their spread. Maintaining and restoring our waters and landscapes can reduce the impacts even when we don’t have other management options to an invasive species.

tropical plant, there was hope that the cold Wisconsin winter would eliminate any plants that were potentially missed by the removal efforts. However, in September 2016, more water hyacinth plants were located in the same area of Lake Winneconne in residential channels and the Wolf River channel. 
Rain runs off your rooftop, onto your driveway, down the street and into the storm drain collecting dirt, debris, fertilizer and other harmful substances along the way. All of the polluted water ends up in our local waters unless we stop the water where it falls!

Clean Boats, Clean Waters (CBCW) boat inspectors and educators will meet boaters at lake and river launches to remind them that by taking simple prevention steps, we all play a vital role stopping the spread of aquatic invasive species (AIS) like zebra mussels.

strategy. Simply put, an ounce of prevention is worth a pound of cure. But if only it were just that simple. The variables and situations that can impact a waterbody may seem so limitless that it can be daunting to know where to start. As a lake resident, you might consider questions such as:
transporting and spreading AIS without proper decontamination. While everyone is required to “inspect, remove, and drain” per Wisconsin State Statutes NR40, these steps might not always be 100% effective especially for high-risk users such as service providers who are often working on multiple lakes in a single day and interacting with lake water and sediment in ways that recreational users are not. These kinds of service providers need to follow the same prevention steps that we all do, but they are not required to take the extended steps, such as spraying equipment with a bleach solution, making it all the more important for consumers to advocate for their lake.

Goldfish were first spotted in Hamilton Harbour in the 1960s, but largely died off in the 1970s because of industrial contamination. In the early 2000s, their population appeared to recover. Goldfish can tolerate a wide range of water temperatures, reach sexual maturation quickly, and can eat nearly anything, including algae, aquatic plants, eggs and invertebrates, Ms. Boston said.
the Fox is a family-friendly event that celebrates World Rivers Day and the Fox River. Activities offered during the event include guided crayfish and critter hunting, guided nature hikes along the Fox River, fishing instructions for children with the KHS Fishing Team, Fox Lock demonstrations – Lock #3 with shuttle available, paper making, photo scavenger hunt, viewing of “The Power of the River” documentary, and river cleanup with Fox-Wolf Watershed Alliance

Extension Lakes. Volunteers met at different local rendezvous sites across the state to learn how to identify AIS such as Eurasian watermilfoil, purple loosestrife, and New Zealand mudsnails, and then searched for them in the field at pre-
selected locations. Initially focused on rivers and streams, Snapshot Day has expanded to include lakes and wetlands. Findings from Snapshot Day are uploaded to the statewide water quality database, SWIMS, where they can be used to track the spread of invasive species and develop management plans.
Snapshot Day’s community-based science approach maximizes the number of sites being checked across the state, and the free event allows volunteers to learn about their local waters and how to keep them healthy. As one volunteer stated, “I enjoyed the hands on learning approach. It was helpful to have well informed guides and samples of the invasive species to get a close look at. Once we had a good understanding of what to look for, it was fun to go out and collect samples of what we were finding.”
