Residents in southeast Wisconsin may have seen plumes of smoke coming from DNR land in the last two weeks. These are winter prescribed burns and are typically conducted in marshes and wetlands, particularly where cattails are present.

These burns are "prescribed" to remove the excess dead vegetation and increase open water for waterfowl to use during the breeding and nesting seasons. A number of these burns have taken place on wildlife areas in Waukesha, Walworth, Dodge and Washington counties.

Why do we do them in winter? To significantly reduce wildfire risk.

Cattails release a lot of heat when burned, and the thick fuels can make suppression efforts difficult. Burning with snow cover allows our burn crews to safely ignite on the frozen marsh while drastically reducing the threat of a wildfire. As new growth begins to appear in the next several weeks, this site will be an attractive spot for our returning migratory waterfowl.

Check here to see a map of where we are conducting prescribed burns around the state.

Questions about shanty removal dates? Take note.

After the deadline for your area, shanties must be removed every day. You can still use a shanty, but you have to be in it -- you can’t set it up, leave to grab lunch, and come back 4 hours later.

All ice fishing shelters must be removed from the ice daily and when not in use by these dates:
✔️ MARCH 15TH for Lake Michigan, Green Bay, Lake Superior, inland waters north of Highway 64 and Wisconsin-Michigan boundary waters
✔️ MARCH 8TH for inland waters south of Highway 64

Deadlines to remove shanties from the ice have already passed for:
✔️ Wisconsin-Minnesota boundary waters
✔️ Wisconsin-Iowa boundary waters

Consumers who buy treated firewood or collect it locally play a vital role in protecting forests from invasive species.

Wisconsin agencies and firewood producers use compliance agreements to minimize the potential negative impacts of trade, including the risk of spreading invasives, while allowing for continued business operations.

'Tis the season for ice fishing! Fishing on "hard water" is a great way to enjoy winter in Wisconsin.

While it may seem like aquatic invasive species (AIS) aren't a concern during cold temperatures, remember to follow state law:
☑️ Inspect
☑️ Remove
☑️ Drain
☑️Never Move

Inspect sleds, buckets, and lures for AIS hitchhikers and remove them, even the tiniest animal or plant fragment, like these quagga mussels. If you added water to a minnow bucket, that bait can now only be used on the same waterbody.

And always remember - no ice is safe ice!

Above-average precipitation throughout Wisconsin has led to flooding, record-high river levels and abnormally wet ground heading into winter, setting the stage for a significant spring flood season.

Some homeowners risk losing their homes due to shoreline erosion or have already seen them fall into the water. The DNR is helping at-risk shoreline homeowners throughout the state by authorizing emergency repairs or preventive measures to save structures.

If your home is at risk, now is the time to contact us about protecting your property. Learn more at

Calling all fourth through sixth graders!

The Department of Natural Resources' second annual Keep Wildlife Wild poster contest has begun! The contest runs from November 1st to February 14th.

Students currently in fourth through sixth grade may submit a poster for the competition. First, second and third place finalists will be selected for each grade level, and finalists will be announced April 5th-11th during our third annual Keep Wildlife Wild week.

Wisconsin's Keep Wildlife Wild initiative began in 2014, with a focus on providing information about wildlife species natural behaviors, tips on how to determine if a wild animal is truly orphaned and what to do if someone finds a wild animal in need of assistance.

The poster design must contain the words "Keep Wildlife Wild 2020" and follow the theme of the Keep Wildlife Wild tagline: "A young wild animal's best chance for survival is with its mother!"

Blue-green algae are a natural part of all Wisconsin rivers and lakes. When nutrients in the water increase, so do algae. This increase in algae, called a bloom, is more common in late summer. Some blue-green algae blooms produce toxins that can be dangerous when ingested.

Local public health agencies can't continually monitor beaches for blue-green algae. Watch for and avoid swimming in water that looks green like "pea soup," appears scummy, or has floating mats that may be green, blue, white, red, or brown. Also, be sure to choose the clearest water you can find for small children and dogs to use.

Dogs won't instinctively know if the water is safe when they jump in, so keep them out of unsafe conditions and prevent them from drinking untreated water. Dogs are especially susceptible to blue-green algae toxins because they swallow more water than humans while swimming.

What should you watch for if your dogs (or you!) have gone swimming in potentially affected water?
💧 vomiting
💧 diarrhea
💧 weakness
💧 difficulty breathing
💧 seizures

Symptoms may begin within minutes of exposure.

If you or your dog exhibits these symptoms or if you think your dog might have been exposed, contact your doctor or veterinarian right away. Learn more at

What’s the “big whoop” about this bird? Whooping cranes are listed as critically endangered in North America, with a wild population estimated at less than 700 individuals. This particular bird, identified by his leg bands as whooping crane 1-17, is a member of one cohort raised in captivity to supplement the wild population.

1-17 was hatched at the Patuxent Wildlife Research Center in Laurel, Maryland in April of 2017. His journey most recently brought him all the way to Jackson County, Wisconsin where he made a special appearance on a Snapshot Wisconsin camera.

With over 2,000 cameras deployed and maintained by volunteers across Wisconsin, it is only a matter of time before another rare species debuts on a Snapshot Wisconsin camera!

It's time for your daily "awe!"

The Loon Project has documented a pair of common loons in northern Wisconsin that adopted a mallard duckling that was likely separated from its family. The duckling has since adopted behaviors atypical for mallards. 🦆

Every summer, the DNR and partner groups band migratory waterfowl across the state.

These photos show goose banding from Green Bay and duck banding from Collins Marsh State Wildlife Area in Manitowoc County. When banded, waterfowl are identified, sexed, aged and released uninjured back into the wild, where they’ll help provide valuable information about their survival, harvest, and recovery rates.

Waterfowl banded at Collins Marsh have been reported as far south as Colombia in South America and all the way up near the Arctic Circle in Canada. One mallard banded at the property even made the 2,900-mile trek to Iceland.

"They're more than a delectable snack for muskrats, otters, and ducks — freshwater mussels are an integral part of aquatic ecosystems. They act as marine kidneys, filtering sediments and nutrients that can spawn algae blooms, as well as pesticides and heavy metals in water." - Milwaukee Journal Sentinel

Freshwater mussels play an integral role in Wisconsin's aquatic ecosystems, yet over half of Wisconsin's 50 native mussel species are endangered, threatened or considered a species of concern.

Mussel monitoring has become an increasingly important job for the DNR's Natural Heritage Conservation program.

Learn how the work gets done in this article by the Milwaukee Journal Sentinel as they interview DNR conservation biologists and mussel surveyors, Jesse Weinzinger and Jason Brabant:

The 2019 Wisconsin spring waterfowl survey results are in, and they show stable to increased numbers for the state’s main species of waterfowl as well as excellent wetland conditions across much of Wisconsin.

The mallard population estimate saw a slight decrease to a stable population, and wood duck populations were virtually unchanged. Estimates for blue-winged teal and Canada geese increased in 2019.

For mallards, Canada geese and wood ducks, Wisconsin remains above the long-term average.
