Back in April, I wrote a post about the regrowth after one of our spring prescribed fires. That’s a fun time of year to burn because the growing season is getting started and the response of green plants pushing through the black ash comes strong and fast. Typically, fall burns don’t show any green-up until the next spring. This year, however, the crazy warm weather has changed things a little. In the two burns we’ve done this fall, most of the ground is still black and barren, but here and there, some green is pushing up through the ash as well.
Here are some photos I took this week of a burn we conducted two weeks earlier. The site was a recently restored prairie (2013 planting) and this was the first burn at the site. Green plants weren’t the only interesting things I found as I walked around.
Big bluestem skeletons stand tall in the ashes.
Cedar trees are uncommon on our land because of our consistent use of fire. This one won’t give us any more trouble….
Despite the lateness of the season, patches of grasses and sedges were showing signs of growth, taking advantage of warm days and some recent rain.
Sedges often stay green well into the winter, but I was still surprised to see these actively growing after a fire.
Among the scorched plants were goldenrod stems with galls. The insects in these galls left well before the fire, but there other invertebrates overwinter in aboveground plants and are vulnerable to dormant season fires.
The bare sand of pocket gopher mounds stand out against the dark background. Ant hills, vole runways, and mole tunnels were also spread across the burned area.
Most plants burned completely, but in some places, fire intensity was lower and bigger stems of sunflowers and other plants only partially burned, sometimes falling as if they’d been chopped down.
Lines of fallen grass and forb stems show where the fire backed into the wind, rather than being pushed by it. In a backing fire, only the lower parts of plants are consumed, and the wind blows them over into the already burned prairie where they escape being further burned.
A white skeleton of a long dead rabbit (I think?) was left tarnished but intact by the fire.
Near the edge of the burned area, grasshoppers skipped away from my feet as I walked.

I recall vividly the moment I was swept up by prairies; when what had only been a textbook description of geography was sparked into a fidelity to place. The view of sandhill cranes swirling over a starkly beautiful late-spring prairie had an immediate impact on me. It was the first time I felt what I was seeing.

I have been recalling this moment lately because I have been thinking a lot about impactful experiences. I was there that blustery Spring morning for work. There was no one there to interpret or inspire. No learning objective or deliberate takeaway. Yet, that experience sits amongst the foundation of where I am now and the path I continue to take. Impactful, emotionally rich experiences are the touchstone for action and commitment, and in prairies, in relation to other landscapes, they seem a little harder to come by. Prairies just don’t give themselves up easily. Identifying those places, characters, and moments that bridge the gap between knowing and caring could be a powerful tool for the achievement of conservation goals, and enriched human lives.
I have often struggled to facilitate powerful prairie experiences for others. Deep appreciation always seems to end up relying on the context of my own knowledge and memories, and thus unapproachable to my companions. One of the few places where prairies do not play hard to get is the Niobrara Valley Preserve (NVP). It has long been a place that confers experiences capable of tying together people and prairies. Its reference list is long and diverse. Somewhere within the consistent transfer of emotional weight that NVP delivers is an important guide and mold for reaching others.

On a recent evening, I found myself sitting quietly beneath a cedar in Niobrara River valley prairie at dusk. Within minutes of my settling in, a small group of bison had quietly foraged their way down from the hills, and into this football field prairie flanked by oak-cedar woodland and the river. They were unhurried, only the occasional soft grunts accompanied the sound of little bluestem, cured wine red, being clipped off. I felt lucky that from the 12,000 acres of prairie on which they could wander, this small group had happened to choose this minute pasture for the evening. They were soon joined by a large flock of Merriam’s Turkeys. Their white tipped tail fans flashed as they scratched at the ground, flipped bison paddies, and bantered with purrs and clucks. A young whitetail buck also joined the evening stage. You can see him inquisitively wander towards me in the video below.
Before it became too dark I walked up and out of the river valley, cresting the hills, and was confronted with the stretching upland prairie of the Sandhills. A spooked pair of young bison bulls thundered off the river ridge and into the hills out of sight. I walked the sandy, two track back to the bunkhouses in the dark. These are not uncommon moments at NVP. The source of gravitas in these experiences may seem obvious, filled with charismatic wildlife, but I think it is more than that. The widely shared appreciation of NVP says a lot about where we are coming from in prairie conservation and where we want to be.

Conservationists will accurately tell you that a 54,000 acre preserve is still far from a whole system. The Nature Conservancy does not control the entire Niobrara River Watershed, our bison herds need to be fenced in, and invasive plants still find their way onto the preserve. However, it is one of an elite few locales that feels whole. I believe it is this sense of wholeness that beckons people to deeply connect with it in a way that is difficult in most other prairie landscapes. When I am showing people prairies, I often find myself asking them to imagine. Imagine if this highly diverse, visually stunning, 80 acres of prairie stretched to the horizon. Imagine if a herd of bison lay hidden behind that low swale. Imagine if you did not know what else might be out there. At NVP, one does not have to imagine, and in that lies its power to move us.
Large, intact, productive grasslands, like the Niobrara Valley Preserve let us transcend the conservation context in which much of our work takes place. We can escape the long road of restoration in the human dominated landscape, characterized by fragmented, degrading, homogenous, biologically depauperate prairies. We can see the prairies and landscapes we are driving at. As prairie professionals and conservationists, we should and do spend most of our time on this long road, but as we seek to bring others into the fold we should strive to impart them with a vision. Head off the question about why prairies are important; the one that often seems to accompany a trip to some isolated remnant in a sea of cropland. Take them to somewhere where the importance of prairies is unspoken and self-evident. Seek to move our potential prairie allies from “is that all?” to “what else is out there?”. I know that is harder for us here in the prairie than for those sharing other ecosystems. It is especially hard in the eastern tallgrass prairie where we have been left with nearly no truly large prairies. That said, the hard work of many (Nachusa Grasslands IL, Midewin National Tallgrass Prairie IL, Glacial Ridge National Wildlife Refuge MN, Kankakee Sands IL/IN) has made it more of a possibility than ever.
For some, the beauty found in small prairie patches is sufficiently captivating. For others, it is the sweeping sea of grass that triggers a love of prairie.
There will always be those who will come to prairies more subtly; those who are innately curious about the details of plant communities, who can discern and explore the intricacies of prairie ecology that happen at the smallest of scales. I will happily continue to walk with anyone who shows enthusiasm for finding fritillary caterpillars on rare prairie violets. Prairie conservation and restoration by necessity has been built on the backs and through the sweat of those who can delight in our valuable remnants, and push forward from there. Let’s also begin to work from the other direction. Recognize that there are those who will only come to prairies through experiences of grand space and wildlife. Bring them to the end, let them see what else prairies can be. After that we can walk them back to where we are, and begin the work of the return journey to wholeness with the expanded support of more “prairie people.”
