What do 400 hours of volunteer stewardship, $7,000 in donations, and 100 hours of social media posts have in common? They are all components of the Illinois Clean Energy Community Foundation’s Community Stewardship Challenge Grant Program.
The Foundation encourages increased local support and participation in the care of habitat by providing grant funds as a match to local dollars raised and labor donated.
Friends of Nachusa Grasslands has been approved for grants totaling $32,000 if we fulfill requirements under several categories:
Friends chose Nachusa’s Orland Prairie, a prairie remnant on the west end of the Big Jump Unit, for its habitat restoration project site. Volunteers have already begun attacking the 23-acre parcel that is heavily infested with the invasive shrub autumn olive. Non-native honeysuckle is also rampant in the area.
Mike Carr, Orland Prairie volunteer steward, who has been working on the unit for several years, says,
“I really enjoy brush clearing, especially the nasty stuff.”
Both autumn olive and honeysuckle are some of the most tenacious foes that Nachusa’s volunteers battle.
According to The Nature Conservancy, “Autumn olive is quickly becoming one of the most troublesome shrubs in central and eastern United States. High seed production, high germination rates and the sheer hardiness of the plant allow it to grow rapidly.”
In addition, a University of Illinois extension website says, “Controlling bush honeysuckle is vital to the preservation of native ecosystems in Illinois. Bush honeysuckle currently poses one of the greatest threats to forest ecosystems in Illinois.”
Saturday workday crews and individual volunteers are using herbicides to kill the woody brush invading Orland. Later this year and early next year, we will over-seed the area with native species collected during the harvest season, conduct prescribed burns, re-contour unsightly gravel pits, and remove non-native trees and large debris from fence rows at the site.
Our long-term goal is to establish a diverse prairie planting on the 23-acre site, providing for long-term weed management and suppression of non-native shrubs and trees. Ongoing stewardship efforts, including volunteer labor, herbicide application, and controlled burns, will gradually help integrate the target area into the surrounding habitat.
How can you help Friends earn the stewardship grant? Volunteer for a Saturday brush clearing workday at Orland Prairie — the next one is on June 9. During the summer and fall, you can also help collect prairie seeds for Orland from the preserve. The Friends Social Media Team uses Facebook, Twitter, Instagram, and our website to promote volunteer opportunities.

Birds are known harbingers of spring. Although most stick around during the brutally cold Illinois winter, we don’t take much notice until they are everywhere in our yard, waking us up in the morning and pooping on our cars: spring time!
It’s finally springtime, and at Nachusa the birds are singing, vying for territory, and finding mates. These aren’t your typical backyard birds like the American robin and northern cardinal, who are your usual early morning alarm and repeating snooze. Nachusa holds a wide variety of bird species, including some of the ones in the most need of conservation: grassland birds. They come with funny names like bobolink and dickcissel, and in all shades of brown and yellow and sometimes black.
Grassland (prairie) birds are declining at a faster rate than most bird species, and a majority of this has been caused by habitat loss. Illinois is the prairie state, but only one hundredth of its original prairie remains. Places like Nachusa are doing their best to restore the agriculture fields and recreate the best prairie as humanly possible. Doing this requires a lot of hard work, hours of picking seed, planting seed, removing unwanted plants, burning portions of the prairie and mowing. The birds seem to be responding to this management fairly well. However, there is an elephant in the room, or shall I say a bison in the prairie.
American bison are our national mammal, and rightfully so. These large herbivores used to roam most of the contiguous United States, until they were hunted to near extinction. I’m sure you’ve heard the story. But now they’re back! Grazing is a crucial disturbance in prairie habitat, providing habitat for a lot of species and open space for a lot of plants. But how will birds respond to this large, iconic grazer on its new home in Franklin Grove, Illinois? When I started my graduate degree at Northern Illinois University in 2013, I was able to start trying to answer that question more specifically by looking at how their nests were going to be impacted by bison.
Bison can impact bird nests in a variety of ways. There are the obvious negative direct ones like trampling and dislodgement, but there are also some not-so-obvious impacts. These impacts can be either positive or negative and can affect the nesting habitat, nesting material, clutch size, and ultimately the survival of the chicks until they leave the nest (nest success). Seeing if bison are impacting nest success means I must find the nests first. This is the most difficult part. They are roughly the size of a compact disc, made from the vegetation they are in, and wickedly hard to find. If you come by Nachusa early in the morning this summer, I’m sure you’ll see me walking in the prairie, waving around a stick, and waiting “patiently” for a bird to fly from the vegetation.
Although difficult, watching these nests through time is a very rewarding experience. I’ve seen nests being built, eggs being laid, chicks hatching, and chicks leaving the nest. Please don’t try this at home, though. Nests are sensitive to human disturbance, and I follow specific protocol to not influence their nest success. Bison don’t seem to be influencing their nest success either, negatively or positively. This is good news. They are one of the main sources of disturbance in the prairie, and it is a relief that they are not trampling nests of birds in decline, at least four years post-reintroduction. Watching these nests is only a part of my graduate research. I am also looking at how bison may influence nest predators, brood parasitism by brown-headed cowbirds, and what bird species are present. So far, I am not seeing anything change enough to be consider a bison impact. Time will tell if there will ever be a noticeable impact of bison on grassland birds. If I were here in ten years, I would try to find out.
The beautiful prairie and bison are a great reason to visit Nachusa, but don’t forget about the birds. Sure, they all look similar and are hard to spot, but they are our harbingers of spring and make the prairie sing in the summer.

Heather is attempting to quantify the effects of bison reintroduction, prescribed fire, and restoration age on grassland bird populations at Nachusa.
