The Nature Conservancy in the Midwest
The Nature Conservancy’s mission is to protect the lands and waters on which all life depends, and for more than 60 years, we’ve been working in the Midwest to do just that.
Every act of collaborative, purposeful action and restoration moves us closer to a flourishing future for nature—and all of us.
Together, we can protect and restore nature, creating a vibrant future for all.
Donate TodayOne year may be a blink in Earth’s 4.54-billion-year history—but in the fight against climate change and biodiversity loss, every year counts. Right now, we have a narrow window of opportunity to act and secure a thriving future for the Midwest and the planet.
The good news? Together, we are making progress toward a future where nature beats the odds. Through our on-the-ground conservation work, we know that a better tomorrow is possible, thanks to the prairies, wetlands, lakes, rivers and forests found throughout the Midwest. These natural areas are helping us save wildlife, great and small, and inspiring us to bring innovative practices to regreen cities, towns, neighborhoods and farms.
How do we do it? By doubling down on what works:
Our work is far from done, but these wins from the past year show what’s possible when we unite for nature. Take a moment to celebrate—and get inspired for what’s next.

Forests, Prairies, Wetlands and Wildlife
By preserving and revitalizing beloved Midwest habitats, we help save wildlife and benefit people.
One of the most powerful ways The Nature Conservancy addresses the interconnected crises of climate change and biodiversity loss is by protecting and restoring the lands and waters that sustain both wildlife and people.
While the Midwest is rich in natural diversity—from forests and prairies to river floodplains—much of this landscape is fragmented and privately owned. That’s why TNC is working closely and collaboratively with partners to connect and restore a network of protected places throughout the region.
Together, through improved management and innovative conservation practices, we’re creating wildlife corridors that allow animals, birds, fish and insects to move freely, find food and shelter and adapt to a changing climate. However, this work doesn't just benefit nature—it also provides benefits such as cleaner air, reduced flooding and healthier environments to communities across the region.
Here’s a look at some of the wins we’ve achieved together this year.
A cerulean warbler calls out to her mate in the forested sanctuary of Wisconsin’s Baraboo Hills. If no one is around to hear it, does the warbler make a sound? Thanks to bioacoustics research conducted by the University of Wisconsin-Madison in these woodlands, the warbler’s metallic, buzzy "zeet" is being captured—along with other bird song, insect buzzes, frog calls and more—revealing the complex, rich soundtrack of the oak woodland.
The information they've gained so far reveals crucial insights about biodiversity and the work TNC does to manage the forest.

To record the forest, small recording devices are strapped to trees in specific areas throughout the habitat. Findings from these soundscapes indicate that actively managed lands in the area, such as Hemlock Draw, exhibit significantly higher diversity and abundance of birds, wildlife and herbaceous plants compared to lands without intensive management.
These results reinforce the importance of TNC’s work in the Baraboo Hills over the past 65 years. Working alongside partners, TNC has protected over 12,000 acres in the area and is actively managing them with prescribed fire, invasive species removal and other science-based conservation strategies.
Formally known as the Soundscape Baselines Project, the study began collecting 24/7 audio recordings in April 2024. The first year of the project concluded this past spring, although work will continue as funding allows.

Securing Crucial Habitats
Here in the Midwest, TNC and our partners have protected hundreds of thousands of acres of prairies, wetlands, forests and other native habitats since 2020. This includes two sizeable wins in 2025.
One is the protection of nearly 3,000 acres of a wildlife corridor in Southeast Ohio in the Appalachian foothills, thanks to an extraordinary donation by private landowner Betty Lowe. TNC in Ohio and Athens Conservancy are working together to conserve the area in one of the largest private land-protection initiatives by nonprofit organizations in Ohio’s history. The heavily forested site is home to some significant plant and animal species, including 26 species of warblers and two federally endangered bats (the long-eared bat and eastern red bat).
Another significant win is TNC’s acquisition of over 12,000 acres of forest and freshwater habitat in northern Minnesota, which is part of the vital Great Lakes Northwoods region. The acquired land features wetlands teeming with wildlife, winding rivers, pristine lakes and vast forests, including some of the best peatland forests in the region, which are home to carnivorous plants and rare songbirds. The newly conserved land will be added to TNC’s adjacent 6,344-acre Sand Lake/Seven Beavers Preserve, nearly tripling its size.

Reconnecting Tradition
This past fall, the Indigenous-led Buffalo Restoration Program celebrated its sixth annual transfer of buffalo from our preserves to Tribal lands. More than 600 buffalo returned home to 18 Tribal Nations via our partnership with the InterTribal Buffalo Council.
This work embodies a deep commitment to Indigenous right relations, honoring the cultural, ecological, and spiritual significance of buffalo to Indigenous peoples while building lasting partnerships rooted in respect, reciprocity and shared responsibility.
Two TNC preserves in the Midwest take part in the buffalo transfers: Nachusa Grasslands in Illinois and the Efroymson Prairie at Kankakee Sands in Indiana.
Nachusa has transferred buffalo to the Menominee Tribe of Wisconsin since 2022, with the assistance of Medicine Fish, a Menominee Nation nonprofit. The first buffalo transferred were the first to connect with the Menominee people in over 250 years since the animals were wiped out in the Midwest.
“Bringing our buffalo relatives home to Menominee lands triggered a wave of healing in our community, bringing us together for feasting, for ceremony, and for song,” says Pilar Gauthier, vice president, board of directors, Medicine Fish.

Farms, Fisheries and Freshwater
Working with farmers, fishers and other partners, we're ensuring we can meet the growing demand for food while conserving our lands and waters.
Improving the sustainability of food production and water use has immense potential to benefit people and the planet. Regenerative agriculture practices can protect crucial sources of freshwater for our communities while improving soil fertility, reducing fertilizer use and storing carbon from the atmosphere. Sustainable fishery practices that prioritize restorative approaches over extractive methods help maintain crucial industries that provide food and economic benefits to both large and small communities.
To support local fishers, farmers, Indigenous Nations and communities who are leading the way in resilient, nature-centered practices, TNC is engaging businesses, consumers, policymakers and others to accelerate regenerative practices and freshwater restoration projects.
Below are a few of our recent wins for food and water.
Once a prominent species supporting Great Lake fisheries, native Whitefish are struggling to produce offspring successfully in many areas of the basin. To restore populations of this iconic Midwest fish, TNC is partnering with the Bay Mills Indian Community, the Little River Band of Ottawa Indians, the Little Traverse Bay Band of Odawa Indians, the Michigan Department of Natural Resources and the Sault Tribe of Chippewa Indians.
We are now in the third year of developing and testing approaches to restore river-spawning runs of lake Whitefish, which were lost in the Great Lakes over a century ago. In 2024 and 2025, a total of 145,000 Whitefish eggs were stocked into the Jordan River, which connects to Lake Michigan. Different approaches were used each year, but both proved to be effective.
In 2024, our scientists documented that thousands of fish successfully hatched and drifted downstream to nursery habitats in the lake. In 2025, we successfully collected young Whitefish in the lake at the mouth of the river, several weeks after they drifted downstream. These efforts demonstrate that we can successfully rear Whitefish eggs in rivers, allowing them to imprint on these habitats and return as adults.
But restocking is just one piece of the plan.
Additional efforts to support this Whitefish work include a new eDNA (environmental DNA) initiative across the Great Lakes basin, which allows us to identify additional river tributaries that could serve as promising spawning habitats for future Whitefish stocking efforts.
Additionally, this year, we completed a comprehensive study of 27 reefs in northern Lake Michigan, which Whitefish and other native lake species use for spawning. TNC partnered with the Grand Traverse Band of Ottawa and Chippewa Indians, the Michigan Department of Natural Resources and the U.S. Geological Survey on this research. The report fills critical information gaps needed by agencies and fisheries to prioritize and plan reef restoration projects for the fish that rely on reefs and the people who depend on these fish.
Regenerative agriculture is farming that works with and restores nature to build healthy soil, protect water and create resilient farms for the future.
A Promising Model for Water Protection
In Indiana, Randy Bales and his son, Brad, from Fairholme Farms, are partnering with TNC to minimize the runoff of excess fertilizer nutrients from croplands into streams, rivers and lakes. While nutrient runoff from farms directly impacts the Midwest's drinking water sources, its impact is felt far beyond our region. Once it reaches rivers in the Midwest, the fertilizer runoff eventually flows into and down the Mississippi River, causing devastating impacts on marine life in the Gulf.
Fairholme Farms is participating in the Indiana Regenerative Agriculture Demonstration Network, a partnership developed by TNC that includes government agencies, agriculture drainage companies and other groups. The network is helping Indiana farmers install edge-of-field practices—or solutions located between or on the edge of fields to slow and filter water running off croplands.
As of November 2025, the network has supported the installation of 23 edge-of-field practices on five demonstration farms. At Fairholme Farms, 12 drainage water management structures have been installed, which function like in-line dams that can be controlled from a computer or smartphone. The structures can be adjusted to hold water in the field, reducing the average loss of nitrogen downstream by 46%.
TNC is pursuing similar collaborations with farmers in Illinois, Ohio, and Wisconsin to help increase the use of edge-of-field practices.

Energy, Family Forests & Greener Cities
By moving quickly and resolutely, we can help ensure a temperate future in the Midwest, where communities flourish and nature thrives.
TNC’s core conservation work is critical to saving the Midwest and the planet from the worst impacts of climate change. By protecting and restoring forests, prairies, wetlands and other native habitats, TNC and our partners are helping these native habitats capture and store heat-trapping gases.
However, nature-based solutions are not enough. To tackle climate change, we also need a full-scale, rapid deployment of clean energy, such as solar. TNC is working to expedite the clean energy transition by addressing a critical issue: the substantial amount of land required for solar and other renewable energy installations. When siting clean energy projects, we must preserve our remaining healthy natural areas. We also need to ensure that there is sufficient land for farming, housing and other essential services.
What progress has TNC seen toward these goals in 2025? Here are a few highlights:
About 40% of the forests in the U.S. are owned by small private landowners. Among these are Sandy Breitenbach and Mary Loyer, two sisters who recently bought 119 acres of forest adjacent to TNC’s Laughing Whitefish Preserve in Michigan’s Upper Peninsula.
Sandy and Mary wanted to ensure the forested property would continue to grow and thrive. “Everywhere, we’re losing forests, we’re losing habitat, we’re facing extreme climate change, so Sandy and I felt we needed to save this place,” Mary says.
Enter the Family Forest Carbon Program.
To assist private forest owners, such as Sandy and Mary, who own at least 30 forested acres, the TNC launched the Family Forest Carbon Program (FFCP) in partnership with the American Forest Foundation in 2022. Sandy and Mary enrolled 64 acres of their forestland in FFCP, which educates landowners on how to manage forests to improve the climate resiliency of their lands, as well as increase carbon storage potential.
“With this program nationally, the goal is to take 2 million tons of CO2 out of the atmosphere by 2030. That’s the equivalent of 5.3 gas-powered power plants’ worth of carbon,” says Matt Dallman, TNC’s Northwoods strategy director.
FFCP is currently in four Midwest states: Michigan, Minnesota, Wisconsin and (most recently) Ohio. Across these four states, FFCP has enrolled more than 14,000 acres and 148 landowners since program enrollment began in 2023.
Voices for Nature
One of the strongest tools we have to advance conservation and climate action is policy—at the local, state and federal levels. Voices—yours and ours—are needed to ensure that meaningful policies, grounded in science, are proposed, shepherded and defended across the Midwest.
In 2025, our policy work produced some big wins—and laid the foundation for stronger partnerships and focused advocacy for our work across the Heartland and beyond.
A Big Step toward Ohio's Clean Energy Future
TNC in Ohio worked with communities and legislators to pass a policy, signed into law on May 15, that will help secure the state's clean energy future. “House Bill 15 will help incentivize renewable energy siting on some of Ohio’s least usable land, including former industrial sites, landfills and abandoned mines,” says Rebecca Mellino, climate and energy policy associate. Read more about the bill.
Two Historic Climate Policy Bills Pass in Illinois
In late October, the Illinois General Assembly passed the Clean and Reliable Grid Affordability (CRGA) Act and the Northern Illinois Transit Authority (NITA) Act.
CRGA will enhance the state’s power grid by increasing clean energy procurement, adding new battery storage and expanding energy efficiency programs. NITA includes $1.5 billion investment in public transport, helping to safeguard and fund train and bus services.
TNC in Illinois partnered with 200 other organizations in the Illinois Clean Jobs Coalition to advocate for these pieces of legislation.
From policy wins to regreening the concrete lots of urban schools, TNC made some big strides toward tackling climate change in the Midwest and laid out examples of how those changes can be replicated elsewhere. Click each box below to read our stories.
