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.

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.

Purple Coneflower?

Echinacea pallida - The True NativeAn interesting article appeared in the August 26 edition of the Chicago Tribune. The gardening section had an article about the Coneflower species and the hybridization that has been done to these popular flowers. Purple Coneflower along with Black-Eyed Susan are the most recognizable and widely used native plants today. The article states that even though the Echinacea species is indeed a native species to the Midwest, it abandoned its native roots a long time ago.

Today we most commonly see cultivars such as Echinacea ‘Sunrise,’ ‘White Swan,’ ‘White Lustre,’ ‘Magnus’ and so on. These varities are hybridized versions of our pioneer prairie plant but are assumed native either due to improper marketing by the nursery trade or because the medicinal uses of Echinacea are widely known and associated with Native Americans. In fact, any “variety” or “cultivar” plant is not a native and the native Echinacea of Illinois would most likely be Echinacea pallida - Pale Purple Coneflower. It is found at select midwestern nurseries that specialize in native plants where they strive to keep native gene pools intact. Never found at the local nurseries perrennial section.

The Tribune article entitled “A Better Coneflower?” highlighted the growing argument between those hybridizers and native plant purists. As the popularity of Echinacea varieties has grown, so has the argument. This maybe an argument that will grow alongside our coneflowers (whichever ones it may be) for a long time. A Wilmette, IL resident who has gotten away from from using cultivars summed it up by saying “If you plant something that isn’t native” she says “It may be pretty but its not as beneficial as it could be.”

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.

New England Aster

New England Aster (Aster novae-angliae)There are a few signs that signal summer’s end and the arrival of fall. Shorter days, cooler nights and kids back in school. One sure sign for me is seeing the beginning blooms of New England Aster (Aster novae-angliae). New England Aster is one of the showiest native wildflowers and a very versatile plant when used in prairie restorations. The plant is suitable for a backyard garden but can also be found growing in roadsides.

New England Aster is native to most parts of the Unites States east of the Rocky Mountains and North of the Mason-Dixon Line. It can be found growing in almost every county in Illinois and Wisconsin and about half in Iowa. It grows around 4 feet tall and prefers mesic soils but tolerates heavy clay. It serves as a host to many butterflies and has an abnormally long bloom period, sometimes over two months. Often times this plant will look stressed when dry and serves as a good indicator of a dry summer and fall. Its strong fiberous root system makes it ideal in erosion control applications.

Be on the lookout this fall for this great prairie flower.

August Rainfall Totals

An August StormThe month of August has come to an end and the region can report rainfall totals of historic proportions. A persistent rain pattern formed early in the month and it did not end until it had caused record breaking amounts in many areas. The city of DeKalb, IL reported 14.27 inches of rain in August and 26.47 inches through meteorologic summer (June-Aug), both records. This reflects what occurred over much of the region. Portions of southwest Wisconsin and southeast Minnesota were declared federal disaster areas with as much as 17 inches falling in several days. The Chicago Metro area received close to 16 inches of rain including a storm outbreak on the 23rd that produced the most violent storm in recent memory. There were many economic and heartfelt losses throughout the area.

Midwest Rainfall Totals from August 18-25The most staggering of statisticts came out of Houston County in southeast Minnesota. During a 24 hour period on the 18th and 19th the county received 15.1 inches of rain, shattering the old mark of 10.84 set in 1972. This 24 hour total was two inches less than the all-time record for a single month, set in July of 1987.

The Galena area missed many of the heaviest rains. In total it received 6.27 inches of rain which fell on 23 of the 31 days of the month, including runs in which rain fell on 9 (17th-25th) and 8 consecutive days (2nd-9th). The normal total for August in the area is around 4.25 inches.

August Rainfall totals from the region (inches):

DeKalb, IL - 14.27;   Freeport, IL - 11.88;   Rockford, IL - 13.82;   Vernon Hills, IL - 15.14;   Dubuque, IA - 6.06;   Iowa City, IA - 8.02;   Waterloo, IA - 10.32;   Belmont, WI - 19.89;   LaCrosse, WI - 20.32;   Madison, WI - 15.18;   Platteville, WI - 11.94;   Prairie DuChien, WI - 8.04
