On March 7th Nachusa hosted a refresher day for the Nachusa and Middle Rock Conservation Partners fire crews. The day was sunny, and spring was in the air—a perfect day to light some prairie fires.
How do you become a fire crewmember?
The Nature Conservancy has three requirements for a potential fire crewmember:
1. Pass the pack test.
This requires each person to carry a 24-pound pack for two miles. The trick is that the pack test must be completed in 30 minutes or less. Long-legged individuals have a bit of an advantage, while short-legged people really need to hustle.
2. Complete the S-130/S-190/I-100 online course work.
These courses are self-paced and give an introduction to the basics of wildland fire training. There are questions at the end of each video section, and they must be answered correctly in order to continue to the next section. Before beginning the online course, candidates must contact Nachusa or another agency that will supervise the fire training, as a sponsor is needed to complete the online course. After the online portion is complete, there is one day of hands-on training.
3. Attend a fire refresher.
Nachusa’s refresher this year focused on learning to use the pumper equipment and hand tools during live fire exercises.

Fire! The very word can conjure up images of terror or comfort. Forest fire, wildfire, or house fire evoke terror, while campfire, hearth fire, and cooking fire suggest comfort. Fire for a prairie or savanna means renewal. Fire is a necessary element in the way these ecosystems evolved. The native peoples of the prairies were using frequent low intensity landscape fires to encourage habitats that fit their needs for hunting, food, and medicine. The natural areas we now manage are dependent on those fires continuing. Fire kills the above ground portions of small trees and shrubs, sparing the oaks and hickories, which have adapted to fire with thick bark and the ability to re-sprout as needed.
After a prescribed burn, the landscape looks bleak, seemingly devoid of life. But this is an illusion. Fire sets back woody plants, encourages wildflowers and grasses, and cycles nutrients.
In just a few weeks vegetation begins to sprout anew. Plants such as wild lupine, foxglove, and ferns flourish after a prescribed burn.
By summer, everything is in full bloom. Wildlife, such as deer, coyotes, foxes, rabbits, squirrels, opossums, raccoons, and birds, such as wild turkeys, red-headed woodpeckers, chickadees, goldfinches, indigo buntings, not to mention the myriad insects, all benefit from the lush environment. In this photo we see some old standing oaks that died from oak wilt or some other oak disease.
Autumn is seed time and root time, returning again to underground. Dragonflies mass, preparing for migration. Migratory birds, such as northern flicker, indigo bunting, and summer and scarlet tanagers also gather in flocks to begin their migrations south. Tree frogs cease singing and bury themselves under logs, rocks, or leaf litter to hibernate the winter. The air becomes cooler. Frost happens with more frequency, foretelling the coming of winter.
Winter is quiet and still but by no means vacant of life and activity. Deer roam about, eating dry grasses or other plants coming up through the snow, as well as twigs and the bark of trees. They also eat acorns or hickory nuts that have not been stored away by the squirrels. Coyotes and foxes prowl for voles or mice under the snow. Because the land is blanketed with snow, it protects the seeds that have been dispersed. When the snow melts in spring, it will help to plant and nourish those seeds. Thus the cycle begins again.

Yes! Spring fire season is here! As a Nachusa Grasslands’ fire crew member, it is time to get ready.
The Nature Conservancy has three fire crew requirements:
Nachusa Grasslands held its 2018 Refresher exercise on March 10. Folks fresh out of S-130/S-190 attended, along with the regular, seasoned crew. Whatever the team member’s experience, the refresher has always been a day where we all take away lessons.
First task of the day — Field test. It helps to take the test in a group. Camaraderie is regenerated as we chat and laugh. Those of the crew who benefit from being taller help those of us who are shorter by setting the pace of four miles per hour. This portion of the day has been nicknamed the “pack test” by Nachusa’s fire crew. Do we call it the pack test because something unconsciously wonderful occurs during the hike that helps reinforce communication and cohesiveness that a crew will need during an actual burn? Are we working together similar to a wolf pack, thus, a “pack” test? Hmm.
Next — Classroom. This is the time to review our various burning methods and first aid/safety. This portion of the day is perhaps the most difficult because we all prefer to be outdoors. There is the benefit that someone typically brings homemade goodies to share.
Finally, we head outdoors to practice! We split into groups and work through various stations.
Equipment Review. If you have ever burned somewhere else, you immediately appreciate the plethora of tools available at Nachusa. The trucks with large water tanks are helpful. The trucks are not as maneuverable as a utility vehicle (UTV), but the big tanks are great because large volumes of water are available on the fire line. In contrast to the trucks, we have UTV’s with smaller water tanks that can access tight or muddy areas. You can imagine this luxury if you have hauled a water backpack onto a fire line. The trucks and UTV’s are only a sampling of Nachusa’s equipment.
Of course, equipment requires preventive maintenance. Before every fire, all vehicles and tools are inspected for common issues. For example:
Vehicle Extraction. The best way to to avoid pulling a vehicle out of the mud is to not get it stuck. Ah, comedian. Truly. . . we talk about being mindful of the terrain, when to have a vehicle in low versus high, four-wheel drive versus two-wheel, and differential lock or not. Then we simulate a stuck vehicle and practice using the new winches on the UTV’s. The new winches are nifty because they have a “remote” that you plug into the anchor vehicle and therefore operate the winch at a safer distance from the vehicles. With this method, you can get a better perspective of the extraction process and know more quickly if the mired vehicle is clear of the mud. Cool.
Vehicle backup. We use the trucks for this station. When the trucks are loaded with the water tanks, hose reels, and water pumps, it is difficult to see behind the vehicle in order to back up safely. It is extremely important to have a spotter to help back up without incident — property damage or, worse, personal injury. Verbal communication and clear hand signals are necessary between driver and spotter. We practice making a straight-on backup, and then also a straight-on backup with a 90° turn — all between cones! Yikes!
Spot Fire Simulation. By far, the most anticipated station of the day — working with fire! Our burn boss, Bill Kleiman, sets a fire in the prairie and radios a “spot fire” to the waiting crew, asking for resources. We respond, separately attack the fire flanks as two teams, and extinguish the spot fire as quickly as possible, always mindful of safety. The exercise is intended to remind us how to actually approach an unwanted fire, and how to quickly and purposefully move to extinguish the fire before it is out of hand. In speedy succession, we think about the crew member up front working the fire hose and “eating some smoke” — might that person need relief? Can the driver see through the smoke? Is the now blackened area cool enough to drive over? Is somebody tending the hose so that it does not catch on fire? What is the wind doing and how is the fire moving? What type of fuels are we in? Is the fire out with the first pass or do we need more resources? Is the fire completely out? Any flare ups — double check, double check, double check.
We gather for our “after action” review; what was good and what could we have done better? Let’s do another!
When our refresher exercises are complete, we head back to the Headquarters Barn for some snacks, beverages, more camaraderie, and end with the feeling of a day well spent.
I love the whole burning process — from initial preparation to the actual burn — to witnessing the various habitats rejuvenate and thrive following the burns. Do you want to be a part of prescribed fire? Contact us, and we hope to see you on the fire line soon!

The unseasonably warm weather created a flurry of activity to prepare the fire equipment in anticipation of the weekend's controlled burn. Nachusa burns typically begin in March.
With the staff committed to speaking engagements, much of the prep work fell on long–term and dedicated volunteers, Dave Crites and Mike Carr. This past week, the men worked hard and swiftly to prepare for the possible weekend burns, loading all the various equipment and pumps to the vehicles.
The burn begins, as the crew uses drip torches to ignite the grass.
Water pumpers follow the igniters and extinguish any fire that burns back toward fire breaks.
The crew has the fire well underway.
Crew members dedicated to fire suppression, put out any unwanted fire, such as around this brush pile (it will be burned later, when there is more time to watch over it).
A dust devil was observed during the burn. What causes a dust devil? McKinnon (2014) explains the interesting science:
The controlled burn is typically set in a "ring" by starting at one point and sending two crews in opposite directions, working into the wind. Near the end, the blackened area is wide enough to allow the two crews to meet up in the middle of the wind side. All the "sides" of fire meet up, and with no more fuel, the flames go out!
After the burn is complete, the Project Director leads a debriefing to go over the events of the day. What did we do well? Where can we improve?
Here is a short video detailing some typical events that occur during a controlled burn at Nachusa. For more information, visit Nachusa's webpage about controlled burns.
