New Title


At Severson Dells Nature Center, we have always been deeply committed to nature conservation. From our educational programs to our Conservation Crew restoration days, our mission is to connect people to nature. Now, we are proud to announce a new step in that journey: Severson Dells Nature Center has officially joined the Global Rewilding Alliance.


But what exactly is "rewilding," and how does it align with our plans for Elliot Golf Course?


What Is Rewilding?

Rewilding is a conservation strategy aimed at restoring natural ecosystems to their wild states. The science behind rewilding focuses on using holistic solutions to remove barriers and reintroduce native species, restoring ecological processes, and allowing nature to reclaim its course. Rewilding supports the mass recovery of ecosystems and the life-supporting functions they provide.


Rewilding vs. Restoration

Rewilding, broadly defined as facilitating the development of self-sustaining, self-organizing and resilient ecosystems shaped by natural processes, differs from classical restoration in a few ways: 

  • rewilding aims for minimal ongoing management in the long term; 
  • it focuses on present and future ecosystem functioning and resilience, allowing the ecosystem to continually adapt and self-organize in response to environmental change


The Science Behind Rewilding

The core scientific principle behind rewilding is the restoration of ecosystems by reintroducing diverse native species and enabling natural processes, such as plant succession, and water cycles, to function as they once did. By doing so, rewilding addresses the biodiversity crisis while also offering a nature-based solution to climate change.


Rewilding and Climate Change

Beyond biodiversity, rewilding offers climate benefits. Restored ecosystems—especially forests, wetlands, and grasslands—act as carbon sinks, absorbing significant amounts of carbon dioxide from the atmosphere. Furthermore, resilient ecosystems are better equipped to withstand the impacts of climate change, such as extreme weather events, droughts, and floods. Rewilding can also restore degraded landscapes that have lost their ecological functionality, turning barren lands into thriving ecosystems that provide clean air, water, and habitat for countless species, including humans.


Severson Dells Nature Center and the Global Rewilding Alliance

By joining the Global Rewilding Alliance, Severson Dells Nature Center is connecting with a global network of organizations committed to rewilding projects. This partnership allows us to collaborate on best practices, share scientific data, and contribute to global initiatives that are restoring ecosystems worldwide.


For us, this step is more than a symbolic gesture; it represents a concrete commitment to rewilding efforts as we restore the Elliot property. Through the rewilding of native prairie, oak savanna and wetland ecosystems, the removal of invasive species, and the promotion of biodiversity, we aim to ensure that the landscapes at Elliot property thrive in perpetuity.


Our Rewilding Plans

Severson Dells, rewilding plans are already underway. Before we purchased Elliot Golf Course from the Rockford Park District, we worked with them to establish an agriculture lease on the property. The use of conventional agriculture on the property is the most efficient way to remove the turf grass and flush the weed seed bank that has accumulated over time. The process will allow us to begin seeding the native prairie in clean soil and reduce the need to fight turf grass and invasive weeds long-term. 

Joining the Global Rewilding Alliance will help us learn from other organizations' efforts and contribute our lessons learned as we go through the process. Some exciting projects include:

  • Native Prairies: By restoring parts of the property into wet (mesic) prairie and dry prairie, we are able to provide high quality habitat for pollinators and ground nesting birds. We are especially excited to restore the old golf course sand traps into sandhill prairie patches. 

  • Restoring Oak Savannas: Once abundant across the Midwest, oak savannas are now one of the most endangered ecosystems in North America. We are working to restore these habitats, benefiting countless species, from migratory birds to native wildflowers.

  • Waterway Rewilding: Our work in riparian restoration will daylight the creek to improve water quality and reintroduce native plant species along riverbanks, benefiting aquatic life, improving flood resilience and regional stormwater management. We are looking forward to seeing the diversity of waterfowl this restoration will support. Sandhill cranes have already been observed on the property and we are hopeful that they will be more regular visitors and in greater numbers. If we’re lucky, maybe Whooping cranes will follow their lead.

What Rewilding Means for Our Community

Our rewilding efforts aren’t just about restoring the landscape—they’re also about reconnecting our community with nature. We believe that by helping ecosystems recover, we are also helping people rediscover the joy and wonder of wild places. Severson Dells staff look forward to developing education programs and volunteer opportunities specific to the work happening at Elliot to involve the public in rewilding, fostering a sense of ownership and stewardship.

We also understand that rewilding involves a shift in thinking. It’s about allowing nature to take the lead, trusting the resilience of ecosystems to heal when given the opportunity. It requires patience, long-term vision, and a willingness to embrace a level of uncertainty, as the outcomes of rewilding are not always immediately apparent but profoundly transformative over time.

Looking Ahead

Joining the Global Rewilding Alliance is a great opportunity for Severson Dells Nature Center to be a part of international conservation efforts and a professional learning community, so we can be utilizing current best practices. As we look ahead, we are excited to deepen our involvement in global rewilding initiatives while making a local impact. Together with our community, we are committed to creating a future where nature thrives.


We invite you to join us in this journey. Whether through participating in our restoration efforts when we get started, attending educational programs, or donating to support the restoration, you can be a part of the rewilding movement here in our corner of the world.


Rewilding isn’t just about saving nature—it’s about saving ourselves, by restoring the wild, resilient ecosystems that make life on Earth possible. Together with the Global Rewilding Alliance and a broad range of supporters, we will make this vision a reality.

The Power of Prairie Roots

By education2.americorps • February 18, 2026
Have you ever looked around and wondered about grass? It may not seem like there’s much to notice about the common golf course, front lawn, sidewalk adjacent sort of grass we see everyday, but if you look below the surface there’s a whole world and history. These often monochromatic, sprawling green landscapes are planted with what is referred to as turf grass, such as Kentucky blue grass, a plant imported to the United States from Europe and North Africa. This style of lawn design was brought to the U.S. from Europe during the 1700s, where long expanses of short green grasses were associated with the manicured country estates of the wealthy and upper social classes. The popularization of this cultural import co-occurred and played a role in the development of U.S. suburban culture in the late 1800s, strengthening through the mid-20th century when it became more widely actionable for people in the middle class. Turf grass now covers app. 40 million acres across the country(an area larger than the whole of Illinois). The planting of monoculture grass areas like this, where there are long stretches of only one kind of plant, came in contrast to the landscapes that grew for millenia on the place we now call the United States. These ancient landscapes were full of biodiversity, and in many areas housed ecosystems where humans functioned as just one part of a balanced set of biological processes. In Illinois specifically, native grasslands–in this region called prairies–used to cover 21 of Illinois’ 36 million acres on their own. Prairies in Illinois formed (and the .01% that still remain still form) unique and powerful living systems. Not only do they create a safe home for many animal species to go about their lives, their root systems push through soil to notable depths, with an average length between 5-15 feet, whereas the turf grass lawns discussed above have roots not digging more than 3-4 inches into the earth. The impact of these root systems is profound, creating long pathways for water absorption, microbial and mycelial growth, and the draw down of excess carbon from the atmosphere back into the earth. Just one acre of restored prairie can sequester(take out of the air and store in root systems) 160 tons of carbon a year, and absorb 65% more stormwater–or water left on the ground after it rains–than turf grass. The transformation of turf grass back to prairie has profound positive impacts on surrounding ecosystems. The restoration project at Elliot golf course will provide a prime example for residents of this region to watch as the land begins to come alive with the myriad colors, animals, and landscape benefits of a prairie in just a few years.

The wonder of the moving earth: what to look out for in the sky during 2026

By Olivia Price • February 18, 2026
Rivers move and snow falls and hillsides weather while tectonic plates settle snugly across the crust of our earth. The wind blows and trees bow down on stormy days, and deep under our feet the molten parts of our planet’s body flow, as above our heads we see the wispy clouds marking the flow of airs of our sky swirling just the same. Just beyond these skies we see the moving pinpricks and round splotches of light which cross our eyelines through each daily cycle, marking just one of the myriad multiscale rotations of our planet, solar system, and galaxy.
