Early last month, the Wisconsin Department of Natural Resources announced a deal to add 100 acres to  Devil’s Lake State Park, expanding recreational opportunities at one of the DNR’s most popular properties. The move also calls attention to the dwindling life of the Knowles-Nelson Stewardship grant program that made the acquisition possible. 

The nearly 40-year-old stewardship grant program has long been a bipartisan success story, allowing the purchase and protection of hundreds of thousands of acres of land across the state. 

Growing opposition to the program within a subset of the Republicans in control of both chambers of the state Legislature — stemming from a combination of antagonism toward land conservation and concerns about the property tax base of Northwoods communities — stymied multiple legislative efforts to re-authorize the program beyond its set expiration at the end of June. 

The Devil’s Lake purchase marks what could be one of the last major actions of the stewardship grant program, which has allocated more than $1.2 billion to conserve more than 700,000 acres of Wisconsin land over its lifetime. 

The program had about $5.5 million remaining as of early April, according to DNR spokesperson Molly Meister. That money is divided into a number of categories, with $2.9 million earmarked for acquiring general easements — agreements with landowners that conserve and protect the land without transferring ownership — and $1.3 million set aside for general land acquisitions. Another $666,667 is meant for acquiring easements specifically for the Ice Age Trail, plus $8,333 for Ice Age Trail land acquisitions. An additional $600,000 is set aside for acquiring land for county forests. 

Meister told the Wisconsin Examiner in an email that the money set aside for the DNR to acquire land itself is expected to be fully used by the time the program expires, while the money set aside for easements will largely be used, but the exact amount is dependent on the agency finding interested landowners. 

“We are currently negotiating with landowners who have expressed a willing interest in selling their land to the department and anticipate all Stewardship general fee acquisition funds to be encumbered before the end of June,” she said.  Easement acquisitions, Ice Age Trail (both fee and easement), and County Forest acquisition is a similar process, but as you have noted, depends on willing landowners looking to acquire an easement versus an outright purchase in the remaining months. We expect a significant amount, but not all, of these funds will be encumbered before the end of June.”

While the program is set to expire, there are ongoing Knowles-Nelson projects around the state that have already been funded through the grant program yet won’t be completed for a few years. Meister said that program staff will close out those active projects before moving to other jobs within the DNR. The rest of the agency has also faced significant cutbacks in recent decades, due to budget constraints and Republican opposition to environmental protection initiatives. 

“It will take several years to close out currently active projects. Staff will continue to work on finishing up these projects,” Meister said. “After these projects are closed out, DNR staff will continue working on other department priorities. Over the past 20 years, we have lost over 500 FTE positions, so there is always more work to do.”

David Grusznski, the Milwaukee programs director for The Conservation Fund, the land conservation non-profit that facilitated the DNR’s purchase of the Devil’s Lake property, told the Examiner that through the stewardship program, the DNR has often been able to function as the last piece of the funding puzzle for projects that conserve land and provide access to that land for the public. 

“It’s very rare that one pot of money funds an entire acquisition, so money is always being leveraged with other people’s money,” he said. “So without the state stewardship funding being able to bring in a portion of that money, we, a lot of partners, are going to be unable to leverage federal dollars, state, city or county dollars that may be available. And we’re going to have to really rely pretty heavily on private fundraising, which is going to be extremely difficult.”

Now, he said, non-profits and land trusts across the state are coming to terms with the pending loss — which will push planned projects years into the future while putting organizations across the state in direct competition over the same pot of private philanthropy money. 

“I think this is all really just starting to set in with a lot of people across the state,” Grusznski said, “as far as the money is not there — what do we do?”

The Wisconsin Department of Natural Resources held a public hearing Tuesday on a request from the AI data center company Vantage for an air quality permit to operate 45 diesel backup generators at the company’s proposed hyperscale data center in Port Washington.

The department has already granted a preliminary approval to the permit request. Members of the public complained at the virtual hearing that the DNR chose not to conduct a full environmental impact assessment — despite southeastern Wisconsin’s existing classification as a high air pollution region. 

Michael Greif, an attorney with Midwest Environmental Advocates, said that all 45 generators operating at once for one hour would emit the same amount of nitrogen oxides as more than 5 million cars driving over one mile of nearby Interstate 43 — or seven times the hourly nitrogen oxide emissions for all of Ozaukee County. Exposure to nitrogen oxides have been tied to respiratory issues such as asthma. 

“It is also one of the first hyper scale AI data centers proposed in Wisconsin,” Grief said. “So it raises new and unreserved questions about energy use, climate impacts, air pollution and public health, and for all those reasons and more, DNR is legally required to prepare an EIS for the Vantage data center.”

Residents of the area put it more simply, complaining about the air pollution they’re already dealing with every day. 

“Our lakeshore is at capacity,” Sheboygan resident Rebecca Clarke said. 

Many speakers also expressed frustration at their lack of a voice in the state’s surge in data center development and proposals. 

“This community has not been given a fair process,” Port Washington resident Carri Prom said. “We’ve been speaking about this process for months. We’ve largely been ignored, and yet, here we are.”

The air pollution permit is one of the DNR’s few chances to weigh in on a data center proposal that has drawn widespread opposition in Port Washington and across the state. The Public Service Commission, the agency that regulates utility companies in Wisconsin, has given the public little confidence it will do enough to prevent electric bills from increasing.

Local zoning boards and city councils, enticed by the promise of property tax revenue, have often signed off on data centers after agreeing to non-disclosure agreements to keep the details away from their constituents. 

“I think things are very backwards, and that we’re proceeding with all of these projects before we even have any idea of how to protect residents,” said Sarah Zarling, an environmental organizer who’s been involved in the data center fight. 

Over the past year, as the number of data centers operating, under construction or proposed has continued to increase, public opposition has grown. Multiple pieces of legislation for regulating data centers were proposed by lawmakers of both parties, yet none passed  before legislators adjourned for the year. Data centers have become a big issue in the Democratic primary for governor and a number of environmental groups have called for a moratorium on data center development until stricter regulations can be put into law. 

Brett Korte, a staff attorney at Clean Wisconsin, told the Wisconsin Examiner in a statement after Tuesday’s hearing that the disconnected government approval process only highlights Wisconsin’s lack of a coherent plan.

“One of the pressing issues related to the data center boom currently underway in Wisconsin is that there is no overarching plan to ensure they don’t harm communities in our state,” he said. “Nor is there even an effort to fully understand the harm they will cause. Local governments make zoning decisions, the PSC approves the construction of power plants and transmission lines, and the DNR implements water regulations and issues air permits.” Yet no state office is responsible for looking at all of the issues raised by data centers at once.

Korte added that a better process for planning future renewable energy sources, stronger carbon emission standards and a more concrete plan for achieving Gov. Tony Evers’ goal of powering the state with 100% clean energy by 2050 would help the state better manage data center growth. 

“No one is asking: Do the benefits of data centers outweigh their environmental harm?” he continued. “That is why Clean Wisconsin continues to call for a pause on data center construction until the state has a comprehensive plan to regulate their development.”

Members of an ad hoc Wisconsin Department of Natural Resources committee are urging wildlife regulators to work with a national expert as they finalize recommendations to guide state beaver management policy for the next decade.

Researchers and conservationists serving on the advisory body — which is largely composed of DNR staff and government and tribal representatives — hope that including additional scientific expertise, and even a potential computer-guided aerial beaver dam mapping survey, could assist regulators at a time when climate change is beginning to significantly alter Wisconsin weather patterns and pose widespread ecological risks.

“We’re taking our species out faster than they can recover, and when we are overexploiting our trout, when we’re overexploiting animals, plants, habitats, that’s going to make us lose these species faster,” said University of Minnesota ecohydrology professor Emily Fairfax, who has helped review and fact-check several beaver management plans and recently spoke to the committee. “I don’t think we have time to wait — full stop.”

A shift would transform long-standing beaver policy that frames the critters as a nuisance species.

The U.S. Department of Agriculture’s wildlife services program has removed beavers and their dams in Wisconsin since 1988 under contract with the state, along with local governments, railroad companies and Indigenous tribes.

At least five states across the Mississippi River basin and Great Lakes region contract with the federal wildlife services program for beaver removal, but Wisconsin stands out among states for the quantity of beavers and dams USDA employees clear, the millions of dollars Wisconsin has invested to do so and the state’s justification.

Current trout policy includes killing beavers 

USDA killed roughly 23,500 beavers across 42 states in 2024, about 2,700 of which were in Wisconsin, ranking the state among the top five in the nation.

In Wisconsin, the agency focuses on abating transportation hazards, such as flooded roadways. But, perhaps most controversially, about a third of sites where USDA traps beavers are coldwater streams.

Wisconsin currently prioritizes maintaining free-flowing conditions on the state’s prized coldwater streams, partly to appeal to its “customers” and their fishing preferences.

But the strategy has faced increasing scrutiny, even among anglers, who are divided over the issue. Some beaver advocates say the state agency charged with protecting and enhancing natural resources shouldn’t let commercial interests unduly guide its decisions. 

In 2025, the agency trapped and cleared dams in more than 1,550 miles of coldwater streams — roughly the driving distance from Milwaukee to Salt Lake City, Utah. The DNR uses proceeds from annual trout fishing stamp sales to finance the annual undertaking.

At least two other states, Minnesota and Michigan, have employed the USDA for trout stream clearing, but at a significantly reduced scale.

The DNR doesn’t know the impacts of these policies on Wisconsin’s beaver population, as it ceased conducting aerial surveys in 2014. Agency staff, instead, estimate beaver numbers and harvest impacts using trapper surveys and voluntary reporting of annual take. Staff believe the population remains stable statewide or is even growing.

Conservationists are calling on the DNR to systematically survey the state’s beaver population. Without obtaining a reliable count, they say, it’s impossible to devise a science-based management plan. Even if beaver removal continued on trout streams, critics say the state could better estimate the population by having trappers register their beaver take, as the DNR requires for turkey, deer, bobcat and bear harvests. 

Meanwhile, an expanding body of research is showcasing beavers’ ecosystem and economic benefits and the drawbacks of removal.

Beaver dams help limit flooding

When beavers remain on the landscape, they create wetlands, which mitigate climate change impacts like drought, wildfires and flooding. Problems thought to be endemic to the American West are now creeping eastward.

Thunderstorms wreaked havoc in southeastern Wisconsin last summer, bringing more than 14 inches of rain to some parts of Milwaukee within 24 hours on Aug. 9-10. Roughly 2,000 homes sustained major damage or were destroyed in the ensuing floods, and the county now faces more than $22 million in public infrastructure repairs after being twice denied federal disaster assistance.

Beaver dams can dissipate torrents of water when the sky opens — even to the city’s benefit.

Using computer models, University of Wisconsin-Milwaukee researchers estimated that the Milwaukee River watershed could accommodate enough beaver colonies to reduce flood water volumes by 14% to 48%.

Wisconsin beaver policy understudied

But scientists face decades of institutional consensus in Wisconsin that beavers degrade stream habitat and threaten wild coldwater fisheries.

DNR fish biologists say that beavers warm water temperatures and plug coldwater streams with silt. When unobstructed, the water bodies, which tend to contain few fish species, flow fast and hard.

“Past studies have identified some positive but mostly negative effects of beavers on trout, and my research builds upon this,” DNR fisheries scientist Matthew Mitro told the beaver management committee. “The option for lethal removal (of) beavers is an important tool that should remain available for resource managers.”

Yet critics charge DNR biologists with managing streams for the primary benefit of one species by trapping out another, justifying the practice using research that hasn’t undergone scientific peer review.

A 2011 academic review of beaver-related research conducted in the Great Lakes region, which predated Mitro’s recent research, found that 72% of claims concerning beavers’ negative impacts are speculative and not backed by data, while the same held true for 49% of positive claims. The negative claims included the idea that beaver dams warm stream temperatures and block trout passage.

DNR biologists often note that academic literature largely has been conducted in the western United States and can’t be directly transplanted to Wisconsin’s comparatively flat landscape.  

That is all the more reason to get off our haunches and wade into beaver ponds, Fairfax said.

“We have to follow that up by collecting our own data sets,” she said. “We have to publish them in peer-reviewed journals and get that scientific stamp of approval.”

Beaver trapping and natural predation are distinct from targeted eradication, Fairfax noted. The former can be sustainable, while stream-wide depopulation and dam removal can damage entire ecosystems. 

It’s also possible that stream clearing prevents beavers from moving to parts of Wisconsin where they are wanted or where they could thrive with fewer conflicts.

Federal government assesses Wisconsin’s beaver dealings 

The DNR beaver management plan’s update coincides with a new USDA environmental assessment of the potential impacts of its beaver and dam removal in Wisconsin.

A conservation organization founded by beaver management committee member Bob Boucher announced its intent to sue the federal agency to compel it to update its previous assessment, published more than a decade ago. Then Boucher threatened to sue the DNR after it wouldn’t release a draft of the new one, currently under review.

The 2013 assessment determined that USDA’s involvement in clearing streams and conflict areas did not significantly impact the beaver population. It estimated wildlife managers would only trap about 2,000 beavers annually, but the agency exceeded that figure within a few years.

The USDA recommends staying the course, using lethal and nonlethal methods. When analyzing alternatives, the agency concluded that other wildlife managers would continue trapping with or without federal involvement.

The USDA allocates some funding for the installation of flow control devices that can reduce the footprint of beaver ponds by lowering water levels. But nearly all beaver conflict sites the USDA handles in Wisconsin are managed through trapping. Levelers do have limited effectiveness in settings like high-flow streams or infrastructure-heavy floodplains. 

Wildlife managers say that they need flexibility because no two beaver sites are identical. 

“We’re not against beaver complexes,” DNR fisheries biologist Bradd Sims told committee members. “We’re not against ecosystem diversity, and I don’t know why people try to paint us that way. We’re an open-minded bureau that’s open to different management styles.”

Trout and beaver proponents do agree that climate change poses an existential threat to biodiversity. While the former group might view beavers as harmful to coldwater streams, the latter see their potential as a partner in creating resilient landscapes that accommodate not only fish, but also frogs, turtles, bugs, bats, birds and humans.

The committee’s next meeting is March 18 in Rothschild, Wisconsin. Ultimately, DNR staff will rewrite the current plan, release a draft for public comment and discussion at open houses, and present a revised document to the state’s natural resources board for ratification.

State funding of the Wisconsin Department of Natural Resources has been reduced by more than $100 million per biennium in the past 30 years.

A key factor: smaller debt payments.

DNR received $334.3 million in state general purpose revenue in the 1995-97 state budget and $226.2 million in 2025-27.

That’s a reduction of $108.1 million, or 32%.

Between the two periods, debt service dropped from $234.7 million to $103.4 million. 

A Wisconsin Reddit user posted Nov. 22 about the cuts.

A 2023 report on DNR by the nonpartisan Wisconsin Policy Forum said those savings have been used to fund Medicaid, K-12 schools, prisons and tax cuts. Republicans have controlled all or part of the state budget process for all but one cycle since 1995.

The DNR is charged with protecting and enhancing air, land, water, forests, wildlife, fish and plants and provides outdoor recreational activities.
