What does a degraded landscape look like?
Take a good look at the image below. The two volunteer stewards can barely walk through this dense thicket of invasive bushes. The sheer number of invasives that reside here have crowded out most other species, and as a result, have limited the possible diversity. In addition, when leafed out during the summer time, the bushes block the sunlight from reaching the ground and therefore discourage native species from growth.
As Orland Prairie’s land steward, Mike Carr led the December 8 Saturday workday into this gnarly section in the attempt to eradicate the invasive brush. At the end of the day, each volunteer stewardship hour was carefully logged, because Illinois Clean Energy Community Foundation has approved this particular habitat as a grant project. When 400 volunteer hours of habitat care have been recorded, Illinois Clean Energy will present $4,000 to Friends of Nachusa Grasslands.
What species are targeted for removal?
How is the brush eradicated?
On this workday the volunteers treated the brush with basal bark applications. The treatment was applied to the base of the bush with either a backpack sprayer or a hand sprayer.
What does a restored landscape look like?
This landscape is also a part of the 23-acre grant project. The area once looked very degraded, but with basal bark treatments and prescribed fire, the brush understory was removed. Then prairie seeds were planted and the photo above shows the successful restored results. This area has been given new life and is on its way to recovery.
Who restores these habitats?
Anyone who wants to make a difference can help with restoration!
Next ICE Grant Workday
Join fellow volunteers on December 22, 2018 for the next ICE Grant Saturday workday. Meet at Nachusa’s Headquarters Barn before 9 am and be ready to restore habitat. If you have any questions about the workdays, check the Friends of Nachusa Grasslands website.
Let’s make a difference together!

Summer is a busy time of year on the prairie with invasive weeds sprouting up and native plants going to seed. That's why every year Nachusa hires half a dozen seasonal staff to keep up with the workload from May through November. Typically the hired staff are in their twenties and going into careers in ecological restoration/conservation.
During May, June, and July we will spend the majority of our time spraying and spading invasive weeds in the hot sun to keep them from taking over the prairie plantings. Backpack sprayers are used to apply herbicide to weeds such as sweet clover and bird's foot trefoil until they start going to seed. Then we will pull them by hand. By mid-August weed season is over and it's time to focus on seed collection.
As each native plant species ripens, the crew will go out and collect them by hand in buckets and barrels. We may collect anywhere between a few ounces to several hundred pounds, depending on the species size and density. After the seed is collected it will be dried on racks in our seed barn and then milled to separate the seed from the chaff. In the late fall the crew will spread the seed we collected in brand new plantings that have not seen prairie in recent years. This year we will plant several areas with a range of habitats. For the most part the seed mixes will be spread using seeders pulled behind trucks and utility terrain vehicles. The crew of 2018 has already covered a lot of ground in weed sweeps and collected some precious prairie plants. Stay tuned for another crew report in the fall!

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.
You can also follow Illinois Clean Energy Community Foundation’s Community Stewardship Challenge Grant Program on Facebook and Twitter to learn more about the Foundation.
Autumn has always been my favorite season. Oaks are my favorite trees. So, it seems fitting in "Oaktober" to write about oaks and oak woodlands
At Nachusa Grasslands and other places in the Midwest, we are trying to restore the health of our oak woodlands. And really, our region is defined by the oaks. The Nature Conservancy calls our eco-region “The Prairie-Forest Border” between the grand prairie to the south and the mixed woodlands in neighboring states to the north. The area was historically maintained as prairie intermixed with oak savanna and woodlands by Native American nations.
Natural plant and animal communities of the region were a direct result of Native Peoples’ use of fire on the land. Without fire, in “The Prairie-Forest Border,” the amount of rain we receive would have yielded dense forests.
Many botanists have defined the various intergrades between savanna, open woodland, and closed woodland by the level of sunlight and density and species of trees. (See https://oaksavannas.org/)
Today, much of our Illinois woodlands have become too shady to allow sun-loving oaks to grow. Shade is the enemy of oaks. Acorns in shade will not thrive after germination and the limbs of oaks will also die if shaded.
How can we tell if the “woods” we are looking at was historically savanna or naturally shady? The presence of large, old oaks with limbs that stick straight out (or used to, but are dead now) indicate the area was likely savanna. An oak growing in full sun without other trees close by will grow limbs horizontally. Oaks that grow close together grow their limbs vertically to reach the sun.
To give the oaks a fighting chance modern prairie restorers make use of controlled burns, as well as actual removal of invasive trees growing under and up into the limbs of the old sentinel oaks. We also remove the non-native bush honeysuckle (and other non-native shrubs) from the understory.
Our region’s historic mixture of prairie interspersed with woodland types — from dry to wet, from open to somewhat shady — had an enormous species diversity of understory flowers, grasses, and native shrubs.
If action is not taken by restorers, the result is a mud forest floor, impenetrable understory with honeysuckle bushes, and an overstory of dead oaks. Elms, maples, and other shade-loving fire intolerant trees move in to take the place of oaks and hickories.
This combination of a solid thicket of invasive honeysuckle and loss of oaks gives hardly any habitat for animals. For example, deer and turkey dislike maple and elm, but they love acorns!
Native oak-hickory savannas and woodlands in the region are disappearing along with bird species that depend on the open structure: red-headed woodpeckers, great crested flycatchers, and eastern bluebirds. Native wildflowers such as kitten tails, wild hyacinth, prairie lily, and starry campion along with grasses such as bottle brush rye, woodland brome, and long-awned wood grass will not grow in heavy shade. And there are the native shrubs: hazelnut, American plum, hawthorn, and Iowa crabapple! None of these tolerate shade either.
I encourage you to read up on oak woodlands, then take a hike. Explore the Stone Barn Savanna and see how we are doing. It’s a work in progress and sometimes messy, but we see the native oak savanna dependent plants and animals are thriving.
Here are some great websites that discuss oak savannas:

Summer is the busiest time of year on the prairie with seeds ready to harvest and invasive weeds sprouting up. So every May Nachusa hires half a dozen seasonal staff to keep up with the workload. Typically the staff hired are in their twenties and going into careers in ecological restoration/conservation. The crew will spend most of the first half of the summer spraying and spading weeds in the hot sun, and then seeds will be collected throughout the summer and fall as they ripen. In the late summer and fall the crew will plant the seed they collected in a brand new planting that has not seen prairie in recent years. This year's planting is 84 acres! The crew of 2017 has jumped into the summer with great enthusiasm and the prairie is already much improved because of their labors.
Meet this year's seasonal staff:
Kaleb Baker — Crew Leader, on his third season he has been an incredible resource helping with many things, including the new Arc Collector Map service. Kaleb will be with us for a couple more months this summer before he attends NIU this fall to start his Masters’ Degree.
Phil Nagorny — on his second season, he started with Kaleb back in March as our Lead Restoration Technician. He brings a deep skill set and experience operating equipment that we will take advantage of while he is here. He will also be attending NIU this fall to finish his undergraduate degree.
Sebastian Schafer — who came all the way from Germany, has been interning with us since March. He is years ahead of most at his age. He is now heading back home to start his Master’s Degree.
Nathaniel Weickert — from Rockford and recently graduated from NIU. Some of you will recognize him, since he has spent many Saturdays volunteering at Nachusa.
Cody Cassidy — is from Rochelle and recently graduated from University of WI Whitewater. Cody is good with his hands, having grown up working with his dad’s heating and cooling business.
Avery Parmiter — From Connecticut and a recent graduate from Clemson University. She brings an array of recent field experiences to Nachusa.
Sandra Vaughn-Pottorff — Originally from Rockford, she recently returned from Hawaii where she studied environmental sciences. She will be enrolling in NIU to finish her undergraduate degree this upcoming school year.
Leah Kleiman — who we all have seen grow and blossom into a mature young independent woman. She recently completed the second year of her Associate’s Degree at Sauk and is eager to gain more experience working on the crew.

It is easy to spot and identify in late autumn. The tall deciduous trees, the oaks, the hickories and others, have but a few brown leaves still clinging to their skeleton frames. Below, on shorter plants, abundant leaves remain green. A drive in the country reveals this late season green plant growing at the edge of a woodlot, deep in a forest or in abandoned fields. It is in the fall that its abundance becomes most visible. It is exotic and invasive bush Honeysuckle.
Nonnative Honeysuckles such as Amur Honeysuckle, Showy Fly Honeysuckle, Common Fly Honeysuckle and others were introduced into the United States from Eurasia more than 100 years ago. They were brought into new habitats for ornamental reasons, for erosion control and for wildlife cover. In the absence of repeated fires and in grazed and disturbed wooded areas the exotic Honeysuckles have reproduced rapidly and spread widely.
There are woodland and savanna areas now in Nachusa Grasslands where the Honeysuckle has become abundant over many decades and is disruptive to the native ecosystems. These multi-stemmed bushes can grow up to twelve feet tall and form very thick shrub layers that prevent the growth of native species by decreasing the amount of light reaching the forest floor and by using up nutrients and water in the soil. Honeysuckles are considered an allelopathic species as they release chemicals into the soil that inhibit the growth of native species. Birds that may build nests in Honeysuckle are more susceptible to predation because the Honeysuckle branches are nearer the ground than native bushes. The abundant berries, while high in carbohydrates, do not produce the fats and nutrients needed by migrating birds in the fall.
I have been a steward of the East Tellabs Unit at Nachusa Grasslands since 2011. With the help of many volunteers, other stewards and the Nachusa crew, we have cut and treated thousands of Honeysuckle plants of all sizes. It is rewarding to use a pair of loppers or a saw to cut a plant near its base and treat the stump with a chemical to kill the Honeysuckle and prevent resprouting. The forest floor is exposed and sunlight may reach it for the first time in years. Other methods of attacking this invasive plant include chemically spraying the leaves, applying chemicals to the base of the plant and seasonal fires.
The work to decrease the Honeysuckles continues. A few hours working among the Honeysuckle can leave one tired, sweaty, sore, scratched and covered in burrs. Yet the tired and sore will go home feeling proud for doing a necessary task that makes a difference in the diversity and ecology of the woodlands and savannas. Each Saturday a Nachusa steward leads a volunteer workday. You might collect seeds, you might pull weeds, you might pile deadfall, or you might cut, treat, stack and burn Honeysuckle.

Of course I am speaking about Queen Anne's lace (Daucus carota), a non–native plant Nachusa Grasslands stewards and volunteers remove from the prairie!
At first glance, the Queen Anne's lace is lovely, with its elegant white flower head and delicate, fern–like leaves. In addition, as you walk amongst a stand of Queen Anne's, you are greeted with a wonderful carrot aroma, hence the plant's "Wild Carrot" nickname.
While enjoying some lively camaraderie, some volunteers used a spade to remove the Queen Anne's, but most of us just used our muscles and determination to pull them out. After all the rain we have had, the roots easily released from the prairie soil.
What a joy to work hard all morning, surrounded by beautiful scenery and the quiet sounds of nature! Yes, the work can be physical (as much as you choose), but there are some wonderful benefits. There are days in the field when I look up from my task, only to enjoy a herd of bison grazing in the distance. A beautiful bird may perch on a prairie plant near me to sing me a sweet song. As I worked with this amazing group of people, I could feel the stress of my everyday life just melt away. I know Nachusa calls it a workday, but every time I volunteer it is actually a "fun day" for me, filled with a lot of good–natured banter (and great snacks!).
Since first discovering Nachusa in 2012, I try to return weekly to volunteer. The prairie is like a big garden to me and boy, do I love to garden! The kind, respectful community of volunteers this preserve attracts, as well as the the wonderful fellowship we share together, also draws me. I love building relationships with these new friends and professionals interested in land conservation. I have gained many new skills and feel my efforts are greatly appreciated and really make a difference. As always, it was wonderful to be a part of the workday and admire the immediate results of all our efforts together. I left that day, with a feeling of euphoria, amazed at what we had accomplished as a group.
Come join us! I promise you a rewarding experience!
