“I’m very happy to save this unique piece of land as it represents not only disappearing habitat but also the very character and uniqueness of the Driftless Area.” — Dr. Marowski, the generous landowner preserving a prairie for future generations.  

 

Ferryville, WI — When Dr. Marowski, a cardiologist living near Milwaukee, stood upon a steep bluff above the town of Ferryville, he was in awe of the stunning view. The Mississippi River, blue and majestic stretched below him, and to the north and south, the unique and ancient landscape filled the horizon. At his feet, he took notice of prairie flowers rarely seen any more and quickly understood the conservation value of the property.  

The diversity of life this bluff prairie holds will now be stewarded forever. In December 2023, Dr. Marowski generously arranged for the protection of his 11-acre property by The Prairie Enthusiasts, ensuring the land will be stewarded and enjoyed for generations to come. Additional support from Mississippi Valley Conservancy, the Natural Resources Foundation of Wisconsin and Wisconsin’s Knowles-Nelson Stewardship Program helped make this protection project possible. Dr. Marowski also gifted The Prairie Enthusiasts with a land management endowment, which will provide resources to steward the habitat far into the future.  

Stewardship of this prairie already began back in July of 2022. Working with Dr. Marowski, The Prairie Enthusiasts Coulee Region Chapter began restoration work on the bluff prairie. Volunteers removed some areas of sumac, red cedars and other aggressive vegetation from the site. There was already a healthy plant community there, with prairie plants like dwarf blazing-star and leadplant, as well as various birds, insects and reptiles that live on the site. The stewardship work that started and will continue in perpetuity will ensure this rare prairie ecosystem thrives.  

 

This land, now named Marowski Bluff Prairie, is situated between Rush Creek and Sugar Creek State Natural Areas and contributes to an important protection corridor linking them together. Even though the remnant prairie at the site is in outstanding condition, it will need consistent land stewardship to remove and prevent tree and woody brush encroachment, which can shade out prairie plants. Part of that stewardship will be returning fire to the site using prescribed burns at regular intervals. The Prairie Enthusiasts Coulee Region Chapter invites the public to participate in upcoming work parties no matter what your experience level. Work parties will be scheduled this winter as weather permits. Additional volunteer opportunities and field trips will be available in the future. Details about work parties and field trips will be posted on the events calendar on our website at ThePrairieEnthusiasts.org.

We All Have Mentors

We All Have Mentors

We All Have Mentors

By Scott Weber

Konrad collecting seed for the International Crane W Foundation at Muralt Bluff prairie, fall of 1980
We all have mentors in nearly everything we do, and restoration ecology is no exception. My mentor, Konrad Liegel, is a person you probably don’t know, but he had a profound influence on prairie restoration and reconstruction in both Minnesota and Wisconsin. He and I were both students of the late Dr. Paul Jensen who taught ecology, evolution, and field biology at Carleton College in Northfield, Minnesota. Paul convinced the college to buy McKnight Prairie, one of the best remnant prairies in western Goodhue County, to serve both as an ecology laboratory and a seed source for restoration projects. Konrad, a student from Plain, Wisconsin, wrote a thesis, “A Guide to the Carleton Arboretum Restoration Project,” a fairly comprehensive work. He, along with other enthusiastic students, began restoring a brome grass field, Hillside Prairie, with a combination of seed plots, seedling transplants, and a sod transplant experiment with the UW Arboretum’s Curtis and Greene prairies as models.

I was introduced to the prairie project in the spring of 1979 by volunteering for a burn. Back then, we had no burn permit, no official burn plan, and no equipment other than matches, rakes, water jugs, and wet burlap to use as fire swatters, but we did have a general notion of backfires and head-fires and which one to light first. By summer of 1979, the project consisted of two seed plots, 1978 and 1979 spring plantings about an acre a piece, plus the sod transplant area of much smaller size. Konrad graduated in spring of 1978, as did many of the student volunteers, so we were very dependent on the help of Dr. Jensen and Konrad’s thesis. I also checked out The North American Prairie, by Dr. John Weaver, and tried to use that to identify the grasses in the new prairie, not realizing that most of it was still brome grass. That is a revelation that most of us have had at some point: virtually all of the vegetation on our roadsides and farmland is not native to North America. Suddenly every prairie remnant, from McKnight to the big bluestem along the railroad right of way, was precious.

 

A geology professor, Dr. Ed Buchwald, became the first Arboretum Director and began hiring two to three students in the summer as Arboretum assistants in 1978, and I jumped at the opportunity to work in the Arboretum with my coworker, Dick Mertens, for the summer of 1979. We repaired the trail network from the erosion caused by runoff from the fields the college rented out but also pulled parsnip in the postage stamp prairie remnants, collected seeds for future plantings, watered transplants, and did other maintenance. As far as prairie restoration went, we were greenhorns. By spring of 1980, I was the “burn boss,” having completed only one other burn in my life, and no one else was primed to take over the project, so I needed some guidance. Dr. Jensen helped us identify plants and locate seed sources, but none of us had much experience starting a prairie from scratch, so I went in search of Konrad. I needed some education from the guy who wrote the book.

 

Konrad returned to Wisconsin after graduation to work for the Aldo Leopold Reserve (now Aldo Leopold Foundation) to construct a pre-European settlement vegetation map of the reserve. He also worked at the nearby International Crane Foundation (ICF) planting the first seed plots on ICF’s newly purchased farm. Konrad’s friend, Charlie Luthin, convinced ICF to include habitat restoration as part of their conservation message, and Charlie planted ICF’s first prairie at their old site closer to Baraboo. A crane disease outbreak at their first site accelerated ICF’s need for a new home, and the new site was a great opportunity to do some major restoration of prairie, oak savanna, and wetlands. Our Carleton Natural History Club visited ICF in March 1980, and I asked Konrad if I could be his intern for fall of 1980.

 

I took the summer of 1980 off from the Arboretum job at Carleton, backpacking with my roommate in the Grand Tetons and North Cascades, and arrived at ICF in mid- August. Konrad assigned me the task of completing the herbarium collection for the site, helping his summer intern, Shelly, finish mapping the oak woodland, writing a guide to prairie seed germination and storage, and, most importantly, collecting and cleaning seed for both a fall 1980 and spring 1981 planting. Konrad kept me very busy!

 

Back then fall plantings were very experimental and rarely done, so Konrad was taking a big chance, especially since future funding and dedication was never guaranteed. Then, as now, speed matters, and warm season grasses and black-eyed Susans come fast in a spring planting. Fall of 1980 was a wet season, and we harvested a bumper crop of prairie dropseed and many other species from Avoca Prairie, Muralt Bluff, Spring Green and Lone Rock remnants, the UW Arboretum, and wherever else we could find seed. Fortunately, being a non-profit, we had access to seed sources normally off limits to private individuals. If we had known then what we know now, the entire five acres should have been planted in the fall, not just the one-acre plot. The dropseed and most forbs, including the gentian seed collected at Avoca, have done very well there, whereas the spring planting became dominated by tall grass. In retrospect, we wasted a lot of good dropseed and forb seed by planting most of it in the spring.

 

I returned to Carleton and worked in the Arboretum again in the summer of 1981 with my coworker, Sue Peterson. Armed with all the knowledge that Konrad bestowed upon us, we not only did trail repair but also sampled the 1978 and 1979 seed plots, learning that brome grass percentage will decrease with fire and competition. We collected seed for another hillside planting, and, based on Konrad’s example at ICF, turned our attention to oak savanna. Saving all the savanna oaks suddenly became a top priority. Converting crop land to prairie before government programs like the Conservation Reserve Program (CRP) and government cost-sharing was difficult since the college needed the rental income, so Sue and I were free to hack away at the buckthorn and non-oak species in an opening Dr. Jensen’s students had studied and managed. That oak opening was the epicenter of the savanna project. Many thanks to Ed for letting us do that at the expense of some trail work.

 

We completed another seeding, about 1.5 acres, on Hillside Prairie and tilled up another acre or so to prepare for another. We contracted all the tillage work to local farmer, Palmer Fossum. Unfortunately, we didn’t have the results from the ICF fall planting, so we planted in spring. There are leadplants and other nice forbs still present after 40 years, but few, if any, dropseed or gentians in those plantings. Eventually the Arboretum Director became a full- time position with several students hired each year, but I’m not sure if Carleton would have as extensive a project as it has now without the vision and commitment of students like Konrad and professors like Paul and Ed. They deserve credit for getting the project going before the college could make a major financial investment.

 

Konrad also worked on other projects in Sauk County, especially the prairie along Highway 12 in front of the Badger Army Ammunition Plant as a member of the Sauk County Natural Beauty Council (SCNBC), part of a nationwide highway beautification program started by Lady Bird Johnson. After I graduated from Carleton, I worked for the Aldo Leopold Reserve, ICF, the Wisconsin Conservation Corp, and volunteered for the SCNBC board. I was either working for Konrad or following his footsteps. I learned almost every important lesson in prairie reconstruction then: the importance of good seed sources, the diversity of fall plantings, how quickly prairie species establish in nutrient poor soil, and the importance of record keeping. Konrad was also very humble; he knew that each of us is just a temporary link in a long chain of human interactions with our environment. We all have to pass the torch and move on at some point.

 

Unfortunately for prairies and ecological restoration, Konrad left his job with ICF to go to law school at Cornell and, soon after, moved to Seattle with his sweetheart, Karen, to gain experience in environmental law, and our paths diverged. Conservation has one of the highest education- to- pay ratios of any occupation, so law was probably the best career choice for Konrad, but not a field that I was suited for. I wanted to spend my time out on the prairie collecting seeds forever!

Paying Attention to the Season During Restoration Work

Paying Attention to the Season During Restoration Work

Paying Attention to the Season During Restoration Work

By Jim Rogala

October 3, 2023

Prairie restoration land managers, whether landowners or those working on public or protected lands, typically have long lists of management needs. I’m no exception. My list contains many lifetimes of work I could do, so I prioritize tasks and tackle urgent needs first. These are typically long-range plans that span years and even decades. However, there is another component to selecting which task to work on at a shorter time scale: seasons of the year. 

I’ve always had this seasonal aspect of restoration in my mind, but that is not very conducive to sharing it with others. As a past member of The Prairie Enthusiasts Education Committee, I proposed doing a simple guide to formalize the seasonal aspect of prairie restoration.  

There are many factors that contribute to selecting which time of the year someone might do a specific task. Some examples are: 

Plant Physiology

The translocation of materials in plants can vary drastically by season, not only in the rate of movement but also the dominance of some movement over others across seasons. Also, there are times when most of the energy in a plant is above ground, and other times it is below ground.  

Herbicide Efficacy

Herbicides have temperature ranges that are best suited for their effectiveness 

Preparation for Upcoming Tasks

Some tasks are simply preparing for other tasks. If the work is not done to meet the requirements of performing an upcoming task, then you may have to delay doing something for a year. 

Snow Cover

The presence of snow is a good time for some tasks and not good for others. 

Keeping such factors as these in mind, it becomes obvious that performing some restoration work is best done in a particular season. Some examples are: 

        • When cutting and treating trees and brush, consider the optimum season to best translocate the herbicide to the location of action. If it is too cold or too hot, and the translocation is slow. Oil-based herbicides also volatilize at high temperatures. 
        • For non-herbicide methods such as repeated cutting, summer is the preferred time because most of the energy stores are above ground. For clonal species, it is critical to not cut in fall or winter if you are not applying herbicide, as this will promote resprouting from nodes. 
        • Mowing firebreaks in preparation for a spring burn should be done before winter to minimize dry debris on the break. 
        • Brush pile burning is best done in the winter when there is snow on the ground. 

The work of the Education Committee, with helpful reviews from our Science Advisory Group, yielded a document titled: Quick guide to restoration practices: Timeframes and general methods. We hope those that are doing restoration find the guide informative and useful in planning seasonal activities. And, as you might notice, there are no seasons with nothing to do!

Quick Guide to Restoration Practices: Timesframes and General Methods

Quick Guide to Restoration Practices: Timesframes and General Methods

Guide to Restoration Practices

Timeframes and General Methods

Story by Jim Rogala

October 3,  2023

The timing of most mechanical and chemical treatments to control unwanted plants is most effectively performed when taking into consideration plant anatomy and physiology, phenology, and the physical conditions of the site. For example, knowing where the cells that translocate materials are located (i.e., anatomy), along with how and when this translocation is occurring (i.e., physiology) are critical. For herbicide treatments, translocation from the point of application to area of action needs to be considered. Many mechanical treatments focus on depleting energy stores and therefore timing to disrupt the translocation is key. There are also weather conditions within seasons to consider, such as rain forecasts prior to herbicide application or hot conditions that slow the translocation process.

Below are some recommendations for seasonal, priority management actions. This information is intended to serve as a starting point for planning the timing of work to have maximum desired impact and not to provide all details related to various methods. Please search for additional information about management techniques as needed.

Fall Tasks

Search for invasives such as honeysuckle and buckthorn that still hold green leaves after others have changed color or fallen.

Cutting and treating woody non-clonal invaders (note exceptions below)

        • Avoid times when things are wet or there is more than 3-4” of snow cover.
        • Do not apply herbicide, especially water-based herbicides, prior to a precipitation event (wait at least 4 hours)
        • Do not use oil-based ester herbicides (e.g., Garlon 4) during the growing season in high-quality remnants if temperature is above 60-65 degrees because of volatilization transfer
        • Follow good practices such as cutting and treating all stems of the plant, apply water-based herbicide immediately after cut and oil-based soon after. Use water-based herbicide in wet areas and use a water-base or oil-base herbicide if above freezing (concentrated Glyphosate mix, 20% active ingredient, works well on species sensitive to glyphosate down to 20 degrees) or oil-based herbicide if below freezing. Many details on herbicide selection and use can be found in currently available resources, especially herbicide labels.

Cutting and treating clonal species such as sumac and aspen

        • Requires that the entire clone be treated in most cases. Consider non-herbicide methods during other seasons (see below).
        • NEVER cut any clonal species without herbicide treatment during fall or winter
        • May need follow-up on some species in the following year

Basal bark spraying

Brush piling after plants have died back

Cutting coniferous trees (late fall to avoid trampling desirable plants during seed production)

Firebreak work (for winter and spring burns). In addition to other break work, mowing grass breaks for spring burns best in fall

Prescribed burning (consider timing of these and if prior management needs to be done first; for more information about prescribed burning, stay tuned for details about our annual conference which includes burn school)

Seed collecting

Seed dispersal

Winter Tasks

(some of these activities are easier and more effective with little or no snow cover)

Brush piling

Brush pile burning when snow is on the ground (add to burning piles to reduce the number of piles)

Cutting and treating woody invaders (note exceptions listed under fall and below; avoid times with extreme low temperatures)

Basal bark spraying

Cutting coniferous trees

Prescribed burning when prairies are snow-free and snow in surrounding woods (consider timing of these and if prior management needs to be done first)

Firebreak work (for winter and spring burns)

Seed dispersal (earlier is better)

Plant plugs while conditions are still moist

Early Spring

Prescribed burning (consider timing of these and if prior management needs to be done first)

Pulling woody species of small size when soil is wet.

Search for invasives with green leaves (e.g., garlic mustard) before others have leafed out. (Although shrubs like honeysuckle and buckthorn can be found at this time, do not cut and treat if the sap is flowing at a high rate).

Flame weed garlic mustard seedlings in May (where leaf litter or grassy fuels are present, do this when conditions are wet).

Pull garlic mustard and dame’s rocket before seeds start to develop.

Seeding can be done in early spring, especially if preparation for seeding includes a burn prior to seeding.

Late Spring

Girdling without herbicide treatment of trees such as aspen (some other species, but not all)

        • Must do all trees for clonal species
        • Do not use this method on black locust.

Seed collecting (disperse after collected for some species)

Summer

Double-cutting clonal woody vegetation, including sumac and young aspen (~July 1 and August 1 for multiple years; no herbicide; not black locust)

Cutting and treating woody invaders (note exceptions listed under fall and below; see comment regarding high temperatures under the “good practices” in the fall section)

Mowing invasive species (consider timing)

Firebreak work (for fall burns)

Foliar spraying (consider timing based on species herbicides)

Root-severing of monocarpic species (e.g., wild parsnip, biennial thistles)

Seed collecting

Dispersal of fresh seed from early flowering species whose seeds ripen early

Eliminating Buckthorn Without the Use of Herbicide

Eliminating Buckthorn Without the Use of Herbicide

Eliminating Buckthorn Without the Use of Herbicide

Story and Photos by Jon Rigden

October 2, 2023

Typical regrowth of buckthorn

Buckthorn is an invasive shrub that has infested many of the forests and bluff prairies of the Upper Midwest, including Hixon Forest in La Crosse where our Coulee Region Chapter has been working to control it. It is known that cutting buckthorn without treating the stump with an herbicide causes it to resprout. It is not known how frequently or how long buckthorn must be cut before it doesn’t resprout, or if it is even feasible to kill buckthorn by just repeatedly cutting it. Friends of the Blufflands has partnered with our chapter to help answer this question by sectioning off an area in Hixon Forest with heavy growth of relatively small buckthorn plants and cutting parts of that area at different frequencies. We hope to be able to determine the minimal frequency that young buckthorn needs to be cut to eliminate it without the use of herbicide. 

Hypothesis

If young buckthorn is repeatedly cut it will eventually not resprout. The minimal frequency after mid-June until the first hard frost at which this cutting must take place is unknown.

Methods

A 400-square-foot study plot was chosen for its uniformity of buckthorn growth. The buckthorn was about waist to shoulder high with the diameter of stems mostly about half to three-quarter inch or smaller. This area was cut close to the ground on June 16 with a handheld brush cutter. The cut stems were gathered and removed from the area, then a second pass was made with the brush cutter to assure that all the stems were cut. The plot was marked off and divided into four sections, each measuring 10 by 10 feet. These sections go up the slope from bottom to top. The four sections were cut at four different frequencies (every 2 weeks, 4 weeks, 6 weeks, and 8 weeks). A border was also cut around this 400-square-foot plot. The nearby uncut buckthorn was used as a control. Subsequent cuttings were done from that date until the first hard frost, which occurred on October 25, 2022. It is recognized that new seedlings from the seed bank would appear and must be taken into consideration.

 

Area before cutting

Cutting schedule (though the actual cutting took place near these dates due to weather or other factors)

10 x 10 feet sections marked off after cutting

On 6/16/2022 a 15 x 50 feet section on Lookout savanna, well east of an area that had been foliar sprayed the previous year and easily accessible from Savanna Trail in Hixon Forest, was chosen for its uniform growth of common buckthorn. The buckthorn was about waist to shoulder tall with the diameter of stems mostly about 0.5 to 0.75 inch or smaller. There were minimal other woody plants present, such as honeysuckle or oriental bittersweet. This area was cut with a weed wacker with a blade close to the ground, the cut stems were gathered and removed from the area, then a second pass was made with the weed wacker to assure that all the stems were cut. Then four side-by-side 10 x 10 feet areas were staked out within this 15 x 50 foot area. Down the slope and separated from the 15 x 50 area by a 3-4 foot cut buffer, a second 10 x 10 area had all the woody plants removed with the traditional cut and treat method using hand held pruners and 20% triclopyr in bark oil with surfactant and blue dye.

Study Plots Two Weeks Later on 6/30

The cuttings proceeded through the year according to the schedule with the last cutting of sections 1 and 3 taking place on 10/25/22 after which a hard frost occurred. Here are the measurements of growth in the 4 sections on this date:

Section 1
Top 5 averaged 1.5 inches of regrowh

Section 2
Top 5 averaged 2 inches of regrowth.

Section 3
Top 5 averaged 4 inches of regrowth.

Section 4
Top 5 averaged 5 inches of regrowth.

Status through the Winter

Photos taken on June 6, 2023

Section 1

Section 2

Section 3

Section 4

A view of the entire plot looking east

Note that some of the stakes fell over during the winter months. Also note that the green seen in the photos is mostly other plants such as violets, not buckthorn, except in section #4. As seen in the photos, sections 1, 2, and 3 were almost identical with some minimal regrowth of buckthorn. Section 4 had significantly more regrowth both in the number and height of the plants.
 
The separate section that had the buckthorn removed by traditional cut and treat was almost free of buckthorn on 6/6/23 with three plants still present. These were likely either missed or not enough of the herbicide was applied to be effective.
Conclusion:
 
Repeatedly cutting small diameter common buckthorn approximately every 4 to 6 weeks starting in mid-June until the first hard frost can be an effective strategy to eliminate most of the buckthorn and be left with very few stems and a much more easily managed population the next year. In this example that meant cutting the area 3 to 4 times from mid June to late October at 4 to 6 week intervals. Of note, the cuttings were done very close to the ground such that almost no leaves were left on any of the plants that had regrown. This might be difficult to replicate in a larger and rocky area.
