The Half-Way Tree

Just south of Brodhead, Wisconsin near the Illinois border stands a living link to our regions past. One of the areas most famous trees. The Indian Half-Way Tree was used by Indians to mark the half-way point between Lake Michigan and the Mississippi River (see map here). Oneida Indians would use this Bur Oak tree as a marker, meeting point, place to camp and a spot to divide the party as some would head in canoe down the Sugar River just west of the tree.

In 1867 the new owner of the land, Charles Warner, saw an Indian chief standing in front of the farm. Pointing to the tree, the chief made them understand that it should never be cut. It never has. The last Indians to utilize this tree was during the spring of 1878 when a father and son stopped for a night.

According to present day experts, the tree is off by about six miles. Today, the tree proudly stands and has been protected by many owners through the years still marking the half-way point along the ancient Indian trail.

Brodhead, WI is within an hour drive from Galena. The tree is located south of Brodhead off of Hwy. 81 on Half-Way Tree Road. The sign and tree are visible from the road.

Galena in the New York Times

“The Nations Official Recorder of Modern Events”Recently, the New York Times featured Galena, IL in its travel section. It was a rather lengthy article and was written from an interesting perspective, a national one. Several people that I know were quoted and I learned about the local real estate climate, among other things.

What does this have to do with nature? Absolutely nothing. But it is great to have the country’s largest and most respected news source feature our town. Read the article here.

Witness Trees

Possible Witness Tree in Lee Co., ILL As 2007 comes to a close it is time to reflect on the past year’s events and changes. One thing that has experienced many years of change are witness trees. Some witness trees have celebrated over 200 New Year’s Eves.

Witness trees were described by surveyors in the early 1800s as they were laying out the grid pattern that would eventually become our property lines today. Early on, in New England, where the first surveying was done, surveyours would pile rocks where section lines would cross, or drive a rod into the ground. These series of property intersections would identify property boundaries to homesteaders who were given land for serving in the revolutionary war. Again, theory met reality. Many homesteaders found it convenient to just move their property marker to gain access to water sources, trees or any other desireable feature. This caused many problems.

To solve this, it was decided that the closest tree to the property intersection shall be scarified with a saw and its distance and direction was recorded as well as the tree type and tree diameter. This kept homesteaders honest and it became the norm as surveyours moved to the Midwest. The surveyors also recorded important observations as soil types, evidence of fires, width of rivers and so forth. Today, these notes are the most important tool used by restoration ecologists.

The witness trees marked by the early surveyours can still be found today. Not many were able to survive our land use patterns and survivors are reaching the end of thier life cycles. Most of the remaining witness trees are Bur Oaks (Quercus macrocarpa), as they are very long lived and were very common in the pre-settlement era. Many of these witness trees served as meeting points for indians and pioneers and helped route the stagecoach trails that traversed through the prairies.

There are many living witness trees remaining in the midwest, but it may take some experience to identify them. They are always very old, are close to where quarter section lines intersect and were reported in surveyour notes. The greatest surviving example of a witness tree that I have seen is located near Sheffield, ILL in Bureau County. The Bureau County Witness Tree was protected by local farmers in 1944 to ensure its longeveity. It is a magnificant Bur Oak and remains healthy due to the openness around it. It is estimated to be over 250 years old - that’s alot of New Years’ parties! Dick Clark has been broadcasting from New Yorks’ Time Square for only 35 years and the Apple has been dropped annually for just a mere 100 years.

The Nebraska Sandhills

Cory South of Valentine, NEI often feature natural areas within a reasonable distance from Northwest Illinois. However, there are some places that are so unique and fascinating that they must be included as an option. In 2005 the Natural Areas Association had its annual meeting in Lincoln, Nebraska. We decided to attend four days of seminars and then head off for a week, exploring the great Nebraska Sandhills that we had heard so much about. Since our first trip it has served as a close destination 550 miles west on route 20.

Photo by Michael ForsbergThe Nebraska Sandhills are not kown by many, other than botanists and cattlemen. It plays second fiddle to the Kansas Flint Hills as the best representation of pre-settlement vegetation on a large scale. The Nebraska Sandhills is an area of 19,600 square miles (1/4 of the state) of sand dunes that are covered in native grasses and forbs with clean lakes and marshes scattered between. Early on, settlers realized that the land could not be farmed and it immediatly became an area conducive only to light grazing. In 1904 the Kincaid Act was passed and it allowed homesteaders to claim 640 acres (a square mile or one section), much more than the 160 acres previously defined by the Homestead Act of 1862. The act was created specifically for the sandhills region and is responsible for the hugeness of the land holdings there today. It is now one of the most remote areas of the United States. So sparse, in fact, that Cherry County is similar in size to West Virginia, while holding only 6,098 people, half of which reside in Valentine, NE. This results in a population density of one person per 1.02 square miles. Only areas of the backcountry in Alaska and North Dakota can compare. Land is discussed in sections and the term “acre” brings up odd looks.

Windmill - Photo by Michael ForsbergBecause of these extremes you have an ecosystem that is largely intact. The cattle density is very low due to the fragility of the sand dunes. The ranchers know very well the damage that can be done once a sand “blow out” occurs. Some of the prairie species that occur in the shortgrass and sandy prairies in the Midwest are also found here and feed the prized cattle. The extensive root systems and sandy soils assist in filtering water of the Ogallala aquifer, the worlds largest, which lies beneath the endless sand dunes. Exotic plants make up only 7 percent of the entire flora here - an amazingly low number when compared to the fertility of the Midwest. The area also supports large numbers of birds and mammals, it is the namesake to the Sandhill Crane (Grus canadensis) and Forbes magazine called Grand Island, NE the number one destination in the world for bird watchers. 

If you travel to the Sandhills region be prepared to not see many people, fill up with gas when you have the opportunity, not sleep at Holiday Inns (we slept at someone’s house once) and be overwelmed by its vastness and ranching traditions. You will also realize that windmill repair and maintenence is an actual industry here. There are several campgrounds and B&Bs throughout and recreational opportunities available, especially near Valentine.

I will never forget the pleasure I had when a hungry sales shark was trying to sell me a timeshare in Orlando, Florida. She asked me where I enjoyed vacationing the most and where I took my last vacation. I didn’t realize that honesty was also the best way to end her sales pitch. The Nebraska Sandhills are located within an easy 9 hour drive from Galena, IL off of route 20.

Hardscrabble Prairie

Just Southeast of Hazel Green, WI is the diverse Hardscrabble Prairie. Named after the original name of the village to be Hazel Green, it is a 140 acre tract. Composed of woodlands, intermittent streams and some oak openings it is the dry prairies that are in the greatest condition and are most notable.

At this natural area you can view the habitat that harbors the globally rare Ottoe Skipper Butterfly along with several rare birds and plants. The fact that one of the dry prairies is located on a North facing slope makes this natural area most interesting. Dry prairie plant communities are usually found on South and West facing slopes as the soil can dry faster and soil tempetures tend to remain at higher degrees.

This prairie is Wisconsin State Natural Area #322 and was officially dedicated in 1997. It is a great representation of dry prairies in the driftless area and makes for a great wildlife watching opportunity.

Curtis Prairie Restoration

On the grounds of the University of Wisconsin-Madison Arboretum is Curtis Prairie. Curtis Prairie holds the unique title of being the world’s first prairie restoration. In the late 1920’s the university decided to take on an experiment in hopes of emulating a Midwest prairie for research and display. The history of this project is very important as this was the first prairie restoration and many of the techniques that we use today were learned here.

The first deliberate attempt to reconstruct an ecosystem began in 1933. The University acquired two farms West of the campus for the future arboretum and a 60-acre prairie site was chosen. The original prairie was broken there in 1836 and there were no signs of that prairie remaining. The idea was sprouted from wisconsin botanist Norman Fassett. In 1929  Dr. Theodore Sperry was chosen to direct the effort with the supervision of  Aldo Leopold and William Longenecker. Around 200 recruits from the Civil Conservation Corp (CCC) were used to execute three different types of planting. One, was collecting seed from prairie remnants along the Wisconsin River and inserting them into the ground. Another was to grow small seedlings in a nursery setting and plant them individually. The last, and most intensive, was to actually dig up prairie sod from remaining prairies and lay it in place. The results varied greatly as the seasonal timing was not known to be as important as it is today. In 1938, the first prairie plants that survived were blooming on the site. Between 1941 and 1946 John Curtis took over and began focusing on controlled burning in order to control invasive weeds which served to be very useful. He also began to study the effects of seed stratification from seed the he was collecting. Throughout his reign as Arboretum director Curtis began emphasizing the timings of the controlled burns and observed the differences. He continued with his prairie management experiments until his death in 1961. In 1962, the prairie was officially named Curtis Prairie in his honor. The experiments have never stopped. Today, soil scientists are using this site to determine weather soils can return to the pre-settlement health after the return of a prairie. So far the answer is, yes. Many invasive species control studies are carried out here as well studies on hydrology shifts and the creation of buffer zones.  

In the 1930’s a newspaper reporter asked Dr. Theodore Sperry how long it would take to complete the restoration, he replied “Roughly a thousand years.” I guess that still holds true. Today, this prairie restoration serves as a testament to the rewards of ecological restoration as a science. Thankfully, we have learned a lot since then and the experimental risks have been greatly reduced, but will never be eliminated. This experiment also reflects the University of Wisconsin and the entire state, as proof of its proggressiveness and its commitment to the environment.

Nachusa Grasslands

NachusaEvery prairie lover or bird watcher in Northern Illinois has at least heard of Nachusa Grasslands. Nachusa is a true ecological gem for Illinois. It serves as the flagship project in the Midwest for The Nature Conservancy and has set the benchmark for a volunteer network that now stewards its thousands of acres.

The story goes that it started in the early 80’s when famous prairie preservers Doug and Dot Wade were birding down the country roads of Lee County and heard a bird song that sounded like the Upland Sandpiper (Bartramia longicauda). When they got out they discovered acres of undisturbed prairie. Immediately, preservation efforts began and The Nature Conservancy bought its first parcels in 1985.

Since then, land ownership has increased to over 2,500 acres that contain several different ecosytems including sand boils and woodlands as well as numerous rare plants, birds and insects. In fact, the first insect reintroductions have taken place here. The Checkerspot Butterfly was transplanted from habitats that were being lost to development and brought to Nachusa where they can monitor its survivability. The Nature Conservancy has been very creative with its donations. They have started corporate sponsorship of new purchases. Today, we have The Tellabs Savanna, named after the large telecommunications conglomerate which donated the dollars for the new tract. An onsite seed harvesting operation was completed a few years ago which helps restore the new acres which are continually being added. In the future a herd of Bison may be brought back to the Illinois prairie here.

Nachusa Grasslands is located Northeast of Dixon and South of Oregon, IL. An information kiosk is located off of Lowden Rd. You can also visit the restored grist mill at the Franklin Creek Natural Area just south of Nachusa. Volunteer stewards lead nature walks through the preserve monthly and many events happen there throughout the year.

Thomson-Fulton Prairie

Thompson-Fulton Prairie - AugustJust a few miles South of Thomson, IL, and a few miles North of Fulton, IL, is the appropriately named Thomson-Fulton Sand Prairie Nature Preserve. Thomson-Fulton is a 212-acre sand prairie that is a great representation of typical Illinois sand prairies. It also serves as a great alternative to those who cannot gain access to The Savanna Army Depot.

Thomson-Fulton has great plant diversity and looks different each time I visit. Being the vegetation is sparce and short, it makes for an easy walk. Reptile lovers may find this prairie particularly interesting as snakes and lizards are found in great numbers. The six-lined-racerunner (Cnemidophorus sexlineatus) are in very healthy numbers here. The state record Bullsnake, Plains Hognose Snake and Eastern Garter Snake were all recorded here in 1997. This prairie serves as a great area for ecological study by scientists from both Illinois and Iowa.

Thomson-Fulton is highly reccomended prairie to visit. It is located west of route 84, 1.25 miles North of Lock Rd.

Spring Green Prairie

Spring Green Sand PrairieOne of the great benefits to living in Northwest Illinois is its access to great natural areas. Some very fine remnant ecosystems are within a leisurely drive. I would like to introduce Spring Green Prairie Preserve. Located just North of Spring Green Wisconsin, this 260 acre tract offers many unusual sights for the plant, bird, reptile, and insect lover.

Known locally for generations as “The Wisconsin Desert” this is a dry and sandy prairie with an upland savanna. The area is owned together by the Wisconsin DNR and The Nature Conservancy with management being performed by the latter. It was designated as a state natural area in 1972. Restoration efforts have been ongoing since and from observations made on my visit, they will continue for a while. At the prairie one can view dozens of rare plants, birds, insects and maybe see a lizard.

A trip to Spring Green Prairie can be done in conjunction with viewing Taliesin, the Frank Lloyd Wright masterpiece. Taliesin is located just South of Spring Green. Viewing Taliesin and Spring Green Prairie together is a wonderful way to view prairie style architecture and prairies themselves. You cannot help but notice how the surrounding landscapes were integrated into Wright’s design.
