Take a listen to the sound of an endangered species – maybe not happy that he’s being followed. That’s an American Marten – caught on video by a DNR biologist in Wisconsin’s north woods this month. That rare footage has now gone viral. The cute weasel-like creatures are endangered here because of habitat loss from logging.

A record-breaking year for outdoor recreation tourism in Wisconsin. Our lakes, rivers, trails and parks brought in $12 billion in economic activity in 2024. In January Gov. Evers in sent a letter to the Trump Administration urging the Bureau of Economic Analysis to finally release the data for 2024. It’s unclear when 2025 data will be available.

The DNR is investigating manure contamination in Trempealeau County. The agency got calls to its confidential warden hotline complaining about animal waste washing off nearby farm fields – and into local waterways. Officials collected dead fish, including brook trout. Farm operators are strongly discouraged from spreading animal waste on land during the winter when it can easily run off into streams and lakes – since there are no plants to absorb it.

A Wisconsin lawmaker on the cover of Time Magazine for its special AI data center issue. Representative Francesca Hong is profiled in the issue because of her recent bill to pause AI data center approvals in the state. The Madison-based lawmaker has raised concerns about environmental harms and cost. In November, Clean Wisconsin launched a petition calling on lawmakers to pause unchecked AI data development.

The Wisconsin Assembly passed a deal to release funding that helps address toxic PFAS contamination in communities across the state. The Legislature created the PFAS trust fund 32 months ago, but since then communities have waited and waited for our state government to create the programs through which the PFAS trust fund can be allocated. Now, an end to that waiting is finally in sight. The Senate is expected to pass the funding deal when it meets in March.

Clean Wisconsin is suing the EPA over its repeal of climate protections. The case challenges the EPA’s rescission of the 2009 endangerment finding, which found that climate pollution is a threat to public health and welfare. Since that 2009 finding, Wisconsin has experienced increases in harms related to climate change including severe and damaging storms, toxic wildfire smoke and more reported cases of tickborne diseases.

A new draft of the Farm Bill would shield chemical companies from lawsuits over pesticides. The latest version of the bill released by House Republicans would prevent lawsuits from farmers and consumers harmed by pesticides. And it would take away state control over how and when a pesticide can be used.

A proposal in Congress to allow 15% ethanol-or E15-in auto fuels year-round could increase water contamination in our state. More than a million acres of Wisconsin land is used to grow corn for ethanol, and increasing E15 use could mean even more land devoted to ethanol. Corn causes more nitrate contamination in Wisconsin waterways than any other crop. More than 80,000 private drinking water wells are polluted with unsafe levels of the chemicals.

Wisconsin and Minnesota partnering on a project to reintroduce endangered mussel species into the Mississippi River basin. Spectacle-case and Higgens eye mussels used to thrive in western Wisconsin rivers and streams, but both became endangered because of pollution and man-made dams. Wildlife officials are breeding and releasing the mussels into cleaner waterways like the Chippewa River.

Environmental groups across the state – including Clean Wisconsin—are calling for a pause in AI data center projects. The groups issued a joint statement calling on lawmakers to develop a strategic framework that will ensure Wisconsin communities are not harmed by the massive power-and-water-hungry facilities. That call includes: no burning of fossil fuels to power AI data centers, and no increases in energy bills to pay for all the infrastructure need to support them.

Wisconsin’s landfills are filling up with food. That’s according to a new study from the DNR. Wasted food and food scraps account for 20% of the trash sent to Wisconsin landfills — the largest single category. And most of that, coming from residents, not grocery stores and restaurants. The agency is working reduce per-capita food waste disposal in landfills by 50% in the next four years.

The developer behind an AI data center approved in Port Washington is backing away from plans to buy up land near Green Bay. Residents in the Village of Greenleaf caught wind of the project when some landowners started getting offers from an undisclosed buyer. Once it became clear the buyout was for a massive data center, concerns about water use and other environmental harms quickly followed. After strong local pushback, Cloverleaf has announced it would no longer pursue that location.

Commercial fishing companies working in the Great Lakes have stopped putting fish waste into area landfills. Every year, about 60% of the fish harvested has been thrown away -heads, guts, skin, scales. Now 90% of fishing companies in the region have pledged to use every part of every fish for products like fish oil and fish meal. The move will cut 8-million pounds of greenhouse gas emissions generated by landfilling.

Neighbors in Kewaunee County upset after large amounts of manure washed off of nearby farm fields and contaminated a local stream that feeds drinking water wells. The DNR says it happened during recent heavy rains and the agency is monitoring the situation. It is not considered a best-practice to spread animal waste on farm fields during the winter when there are no plants to absorb it, although some farms are permitted by the state to do it anyway.

The EPA is going to stop considering public health benefits when evaluating air pollution limits. For decades the agency has calculated the cost savings of avoided hospital visits and premature deaths that come with stronger air pollution rules. But now the agency will no longer consider those calculations that have long been used to justify air pollution protections.

Families and businesses across Wisconsin will likely help pick up the tab once again to keep coal burning in another state. The Trump Administration is ordering two aging coal plants in Indiana to stay open, even though energy regulators there say they are not needed. The cost to bring the plants back online is expected to reach tens of millions of dollars and will likely be paid through price increases on customers across the Midwest grid, including here In Wisconsin. Wisconsinites are already paying higher bills to help pay for a plant in Michigan that the Administration ordered to restart last May.

Residents in the northeastern Wisconsin town of Greenleaf say they’re getting offers from an AI data center developer to buy their land. According to local TV reports, the land parcels targeted are between Highway 57 and the East River. It’s unclear what company is behind the offers.

Wisconsin soybean farmers are pushing the EPA to finalize rules allowing a controversial herbicide back on the market. Dicamba is used on soybeans and cotton that has been genetically modified to resist the weedkiller. But it has a tendency to get into water supplies and drift in the air, hurting other plants like orchards, gardens and trees. The EPA will now require the Dicamba to be mixed other chemicals to help stop drifting.

If you’re still searching for a Christmas tree and are wondering which is better for the environment — real or plastic. Turns out, it’s real. Experts say plastic trees are usually shipped thousands of miles from China and eventually wind up in landfills. And for every real tree that gets taken home, farmers replant 1 to 3 trees in its place.
