The Power of Prairie Roots

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. One acre of restored prairie can sequester(take out of the air and store in root systems) 1 ton 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.

Gamifying the Outdoors

By Emma Zimmerman • June 17, 2026
There is no better way to spend your summer than outside! Whether you're hiking through the woods or simply enjoying a walk with friends, spending time outdoors has countless benefits. At Severson Dells, our hiking trails and Nature Playscape are always free and open to the public. But if you're looking for a new way to experience nature, why not turn your next outdoor adventure into a game? Gamification is the process of adding elements of games, such as challenges, competition, and rewards, to everyday activities. Gamifying the outdoors can make spending time outside more engaging, especially for families, kids, and between friends. Here are a few ways to gamify your next outdoor adventure.

The Potential Slowdown or Shutdown of AMOC, the Atlantic Meridional Overturning Circulation

By Emma Zimmerman • June 11, 2026
The ocean, and all of the water in it, is constantly in motion. Though it may sometimes appear calm on the surface, enormous currents continuously move ocean water around the globe like a giant conveyor belt. These currents regulate weather, move nutrients across ecosystems, and shape the climates of entire continents. Currents on the surface of the ocean are controlled by the wind, but deeper in the ocean currents are controlled by water density in a process known as thermohaline circulation . Thermohaline refers to the temperature (thermo) and salinity, or saltiness, (haline) of the water. Circulation refers to how the water moves throughout the ocean from pole to pole. Though this is a complicated sounding word, the process is actually pretty simple. Here’s how it works: As ocean water travels toward the poles it becomes colder, and when it gets cold enough, it eventually begins to freeze and forms into sea ice. What is important about this process is that when seawater freezes, the salt is left behind in the surrounding water. As a result, the surrounding water becomes saltier, colder, and in turn becomes more dense than the water around it. Eventually, this water becomes dense enough to sink deep into the ocean, and warmer surface water moves in to replace it. This process of freezing, melting, and replacement continues on and on, resulting in a continuous cycle of moving water that forms deep ocean currents, often referred to as the “global ocean conveyor belt.”

June Climate News: 2026 Fire Season Is Becoming a Fire Year

By Emma Zimmerman • June 4, 2026
Experts are warning that 2026 may bring a record wildfire season to the United States, so severe that many researchers and fire agencies are no longer calling it a “fire season” at all. We are off to such a start that experts are now referring to it as a fire year. Traditionally, the wildfire season in the United States peaks between May and October, but we have seen many fires throughout the southern and western United States already this spring. Most major fires occur in western states. However, impacts from wildfires can be felt across the entire country, including here in northern Illinois. Wildfire smoke can travel hundreds or even thousands of miles, affecting our air quality here in Rockford. Maybe you recall the hazy skies and dangerous air quality alerts from the last few summers caused by fires burning far away in Canada. Unfortunately, these days are not going away, and if anything, we should expect more of them in the future. So why is this year a “fire year”, and why are experts concerned? Let’s dig into it.
