The best ideas surface when friends meet new friends over coffee. In 2008, Rene Dankert invited me to meet Lisa Haderlein and Linda Balek for coffee and brainstorming to develop a fundraiser for TLC, and Art of the Land was born.
The thrill and outpouring of support from our first Art of the Land event, 11 years ago, has grown into TLC’s major annual fundraiser. I’ve enjoyed volunteering to gather artists, helping hang the exhibition at the Starline Factory, and being able to show and sell my own paintings to support TLC. It amazes me to reflect on the size and attendance of the early events compared to how much it has grown and elevated in recent years. I’m proud to have been a part of this beautiful fundraiser, which has benefitted our community for so long.
Another friendship developed through TLC is in my own backyard. I’m lucky to live behind Randy and Nancy Schietzelt, who maintain the Wingate Property. Upon moving to Crystal Lake from Portland in 2002, Nancy explained how their property is held in trust to remain protected by TLC in perpetuity.
My family and I have benefitted being adjacent to this lovely acreage because their special prairie plants and flowers have spread to our property! Randy taught my husband, Paolo, about warding off garlic mustard and other invasive species, so I feel our yard reflects the same care and value as the Wingate Property.
As an artist, I am grateful to TLC to be able to gather inspiration through the beauty in my own backyard.
I felt such joy yesterday at Shrub Club seeing a tray of hackberry trees sprouting!
I had my doubts about whether we would get anything from the hackberry seeds. The main issue was the seeds are small and non-descript, and when we were sorting, there were several moments when I realized that what I thought was a seed was actually just a small ball of dirt.
Growing up, I disliked hackberries. The bark was lumpy, the leaves were irregularly shaped, plus the leaves often seemed to be covered with bumps like they had some disease. It has only been as an adult that I have come to love this tree.
From the USDA, hackberries are great habitat trees for the following species: Wild turkey, ring-necked pheasant, quail, grouse, lesser prairie chicken, cedar waxwing, robins, and other bird species consume common hackberry fruit, which persist throughout the winter. Small mammals also consume the fruit. Deer will browse common hackberry leaves in the absence of preferred browse species. Common hackberry provides good cover for species such as mule deer, white-tailed deer, upland game birds, small non-game birds, and small mammals.
The hackberry is also important habitat for a large number of butterflies like the Hackberry Emperor, Mourning Cloak and Question Mark, in addition to a wide variety of insects that are important food for birds!
And that explains the bumpy leaves. The bumps are insect galls, which are basically tiny insect biospheres. From Wikipedia: Insect galls are the highly distinctive plant structures formed by some herbivorous (plant-eating) insects as their own microhabitats. They are plant tissue which is controlled by the insect. Galls act as both the habitat and food source for the maker of the gall. The interior of a gall can contain edible nutritious starch and other tissues. Some galls act as "physiologic sinks", concentrating resources in the gall from the surrounding plant parts. Galls may also provide the insect with physical protection from predators.
If you'd like to get in on the Shrub Club excitement, join me at Glacial Oaks Nursery Tuesdays from 5-7 and Sundays from 2-5! This is an exciting time now that the weather has finally warmed - everything will start popping now!
Glacier Oaks Nursery is located west of Harvard at 8216 White Oaks Road. From Harvard, take 173 west through Chemung to White Oaks Road. Go north for 2.2 miles, and turn right (east) in the driveway with the white farm house. Please pull into the second driveway (the north one) because there's better parking from that side.
The month of May is officially Invasive Species Awareness Month in Illinois!
The goal of the month is to help every resident of the state find out what he or she can do to help stop the spread of invasive plants, animals, insects and disease.
So, where to start?
Well, here is some info on a few of the most problematic invasive species one is likely to run across in this area:
1. Garlic mustard. Leaves on first year rosettes are green, heart shaped, and 1-6 inches long (shown to the left). Foliage becomes more triangular and jagged-looking as the plant matures. The plant is low growing, most often found in woodlands, and smells like garlic when crushed. Garlic mustard is a biennial, meaning that it only lives two years: in the first year it only has leaves and builds its roots; in the second year it uses the energy in its roots to grow flowers and produce seeds - lots and lots of seeds. And those seeds germinate the next year and the cycle starts all over again. This plant is a problem because it crowds out native woodland plants like shooting stars and trillium. Garlic mustard has also been implicated in preventing young oaks from sprouting.
2. Buckthorn (Glossy and European). This tree (or shrub) has dark green, oval leaves about 1-2 inches across. European buckthorn branches have thorns at the tips and the inner bark is orange, so it is very obvious when cut. Glossy buckthorn (shown in photo to the right) is very similar but grows in areas that are more wet. Both varieties of the tree produce purple to black berries in the fall. The berries are eaten by birds which then disperse the seeds. Buckthorn starts to grow earlier in the spring than native trees and shrubs, and it stays green later into the fall than most other plants. The tree was brought to the US from Europe as an ornamental (decorative) shrub. And in some communities, Buckthorn are pruned into topiary sculptures and revered for the dense, thorny screen that they provide between neighbors. Well, in natural areas, buckthorn wreaks havoc by shading out other shrubs, young oaks and all of the typical woodland herbaceous plants. Soon, the only things growing are buckthorn and maybe some garlic mustard.
3. Honeysuckle (Tartarian and Amur). Tartarian has red flowers and amur has white blooms shown to the left). Both have ovate (almond-shaped) leaves, but the Tartarian's leaves are blue-green and 1 1/2 to 2 1/2 inches long and the Amur has leaves that are dark green on the top and light green underneath. The shrubs are native to parts of Asia and were introduced to the US by way of a Russian Arboretum in the late 1890s. Despite warnings by the Morton Arboretum in 1924 that the plants were weedy, the US Department of Agriculture recommended planting them for erosion control and wildlife habitat until 1984. Their leaves are the first to emerge in the Spring, and like buckthorn, they shade out native shrubs, young trees and herbaceous plants.
4. Gypsy moths. The caterpillars emerge in the first part of May (when serviceberry starts to bloom), growing steadily as they feed on tree leaves. They feed at night, then hide in tree bark or the ground during the day to avoid being eaten by birds. Their presence is usually first noticed when one sees that the leaves on a tree look lacy (since the caterpillars don't eat the leaf veins). If the infestation is limited to just a few trees, one can remove the caterpillars as they climb down the trees in the morning. Larger infestations require professional help from an arborist. The moths emerge in mid July. Females are white and do not fly, so are fairly easy to spot (one is shown to the right laying eggs). They lay masses of eggs that look like smears of peanut butter on tree branches and other surfaces. One can scrape the egg masses off when spotted, but be sure to scrape them into a container and destroy them. If they are scraped onto the ground, they may still hatch! The gypsy moth was brought over to the US from Europe, and it is a problem because infestations can completely defoliate trees. If defoliation happens several years in a row, the tree can be killed. Oaks - McHenry County's signature native trees - are a favorite of the gypsy moth.
Now that you know more about the impacts of non-native species, how will you celebrate this month?
I have a few suggestions:
1. Pull garlic mustard at a local woodland.
2. Cut buckthorn and honeysuckle at a local natural area.
3. Plant native plants in your yard.
4. Inspect your trees for evidence of gypsy moths.
The important thing is to do what you can - everything helps!

The last year or two, I’ve noticed changes to the farm fields I pass on my commute between Harvard and Woodstock each day. The hedgerows are thinning and in some cases, disappearing altogether.
As used here, the term hedgerow means a linear strip of vegetation (trees, shrubs and grasses) that runs along the fence line – or property boundary – between fields.
A hedgerow provides a wind break, which in turn reduces the amount of exposed soil that blows off of a farm field each year. It also reduces the amount of blowing a drifting snow, which can be a severe problem along US Route 14 between Harvard and Woodstock.
A hedgerow provides valuable habitat for a diversity of wildlife including deer, fox and birds. A hedgerow provides shelter that allows mammals to pass safely across the landscape and offers insects and birds a place to rest, nest and/or feed.
On some properties, hedgerows are the only place where old oaks are still found. When land was cleared one hundred of more years ago, farmers left many of the trees that were located on or near the property line. Over the years, these trees provided a comfortable spot to have one’s lunch on a hot summer day in the fields.
So, why are the hedgerows disappearing?
The high price of a bushel of corn.
Just ten years ago, the price of a bushel of corn was less than $3. Now that same bushel of corn sells for more than $6. And that was before the 2012 drought. Farmers are looking for additional land where they can plant corn to maximize production. And at 150-200 bushels an acre yield, even one additional acre of corn will generate $1,000 or more.
Demand for corn is high due in large part to federal Clean Air mandates that require blending ethanol with gasoline to reduce the emission of carbon monoxide. Increased use of ethanol also reduces America’s dependence on imported oil. Both seem worthy causes.
But the world is never that simple, is it? Corn is also needed for livestock feed and has become a staple in American processed food (high-fructose corn syrup, corn starch/baking powder, and corn oil being just a few).
So, basic economics tells us that competition for a product drives up the price, and scarcity (like happened in 2012 because of the drought) will drive up the price even more.
I’ve heard some folks say: “Most of those trees and shrubs are just junk anyway: box elders, buckthorn and honeysuckle.” Sure, but the wind doesn’t pay attention to what tree species is blocking it, and a bird that needs to take a break doesn’t mind if the only resting spot is a honeysuckle bush.
What does matter is whether there is something versus nothing, and the removal of more hedgerows for a few more acres of corn will have an impact on the future productivity of the land and the sustainability of the area for wildlife.
As the soil and birds start to disappear, we all may be wishing those hedgerows were back in place.
I heard an amazing speaker at MCC recently, Jon Erickson, Dean of the University of Vermont’s Rubenstein School of the Environment and Natural Resources. Erickson is an economist, which would normally have kept me away from his talk, but he is unlike any economist I have ever heard, and I am very glad I went.
The field of economics has focused largely on measuring “economic” growth – things like sales, production and jobs. A term you may have heard is “GDP,” or Gross Domestic Product, which is the traditional way of evaluating a country’s economy. In the GDP system, things like hurricanes, pollution and crime all end up being positive for the overall economy because they lead to increased spending.
That sounds absurd, doesn’t it? Maybe so, but that has been the dominant economic measuring system since the 1950s!
Back in those days, Americans didn’t think about pollution, or things like “running out of oil.” We were building the Interstate Highway system, encouraging every American to own a car and buy a home in the suburbs. We were spraying mosquitoes with DDT, and pumping new-fangled chemicals over our farm fields to increase crop yields. Bigger and faster meant better. Gasoline cost 15-cents a gallon, and one could stick a straw in the ground in Texas and oil would flow!
Starting in the 1960s, the environment began to degrade as a result: eagles nearly went extinct, rivers caught on fire, Love Canal was brought to light – along with thousands of similar (but less well known) toxic waste dumps.
And, yet, forty years later, and the field of economics is only now starting to officially recommend ways to factor in the costs of “growth” – costs to our quality of life today and costs to the ability of future generations to have a good quality of life.
Erickson explained that there is a growing movement among economists to replace the old focus on measuring financial growth as an indicator of success with a system to measure resilience.
In the new system, one calculates the GPI (Gross Progress Indicator) for a state, city, country or business by taking the traditional measures related to how much money changes hands (buying and selling goods and services), and factoring in the social conditions (crime, education, war, volunteerism, divorce and health) as well as the environmental costs and benefits that include pollution, resource depletion (e.g. coal and oil extraction) and the effects of climate change.
Imagine an economic system that doesn’t treat a hurricane – or a war – as “good” for the economy. That’s crazy!
I am fascinated by water.
Humans can only survive a few days without it, and our bodies are 65% water. Less than one percent of the water on planet earth is available for people to use because the vast majority of water is in the oceans (where it is too salty for humans to drink) or it is locked in the polar ice caps.
Water is so essential to life, yet so often taken for granted.
Here in McHenry County, all of the water people use comes from the ground. Municipal and private wells reach down into “groundwater aquifers” and pump water up to the surface.
Aquifers are not underground pools. In this area, aquifers are found where deposits of sand, gravel, or sandstone have water filling the spaces between sand particles (or filling cracks in the rock).
If the water in these aquifers is not replenished, they can run dry just like a river or pond can go dry. And the source of water to refill an aquifer is the same as that which fills our rivers and ponds – precipitation (rain-sleet-snow).
We had a severe drought last year. On average, our area receives about 37 inches of precipitation each year. In 2012 we received about 25 inches.
The drought of 2012 led many local rivers and streams to run dry (like the one on the left side of the accompanying photo). Many ponds are very low, and some have dried up altogether. Farmers are able to cultivate parts of fields that were too wet to farm just a year or two ago.
Groundwater aquifers face a double whammy during a drought. First off, people pull more water out of the ground to water their lawns, gardens and farm fields to compensate for the lack of rain. Additionally, with no precipitation, there is no new water to replenish the water we are pulling out of the ground.
There is one final challenge that aquifers face when there’s a drought. They take time to recover even when rain starts to fall again. After all, the precipitation must be able to soak into the ground is areas where the soil is permeable enough to allow the water to pass through 100 to 400 or more feet of material. It can take several years for water that hits the ground today to make it to the nearest aquifer where it becomes available for a well to pump to the surface.
So, if you are still looking for a resolution for 2013, how about “I won’t take water for granted”?
While driving late one night between Woodstock and Harvard, it struck me how dark it seemed. Most house lights were out, so the landscape visible along Route 14 was dark. It was a new moon, so there was no moonlight from the sky to illuminate the ground. I thought to myself: the world must have looked like this for the early settlers.
Not even close.
When early settlers arrived in this area, they would have found actual darkness. The kind of darkness where the Milky Way was not only clearly visible, but where the Milky Way actually cast a shadow on white surfaces!
There are still a few places in the United States where true darkness can be found, but these dark spots are increasingly rare. According to information found at www.cleardarksky.com, there are no places in the entire state of Illinois that have no light pollution. In fact, east of the Mississippi River, a person would have to travel some distance into the Atlantic Ocean to reach a place with zero light pollution.
Woodstock is right on the fringe of a light bubble that surrounds the City of Chicago and most of the suburbs. This light bubble stretches from University Park in the south to Deer Park in the north, and from Lake Michigan in the east to the Fox River in the west. In this area (a place where it never actually gets dark), the sky is perpetually grey or brighter, and only the brightest stars are visible to the naked eye. In technical terms, this bright zone is considered Class 9, Inner-city sky.
Woodstock is in an area considered Class 6 or 7, Urban/Suburban sky. The Milky Way may be visible if directly overhead, and the horizon glows with a faint light that obscures all but the brightest stars.
Heading northwest from Woodstock, the sky is rated a Class 5, Suburban Sky. In this area, the milkway is visible when overhead, but is washed out. Clouds appear brighter than the sky behind them.
In a truly dark, Class 1 or 2 sky, clouds will appear as “black holes” that appear deeper than the starlit sky around them. This is because there is not ground light pollution to illuminate them from below.
Now, there are those who will ask: “so what?”
The sky is part of humanity's cultural inheritance: a door to the Universe, part of the rural environment, and a social amenity. Light pollution reduces the celestial spectacle to a pale imitation - a few pin-pricks of light from the planets and brightest stars - and robs us of a source of inspiration which until recently could be taken for granted.
Some folks may think that with the onset of winter, we can stop thinking about invasive plants - after all, they aren't growing in winter, right? Well, while we may not have to worry about them growing during the dormant months of winter, natural area managers find that this is the best time to work on removing invasive shrubs, trees and vines. After all, one doesn't have to deal with ticks and mosquitoes, plus, with the leaves off, it is much easier to cut and mulch (or burn) brush.
The picture above shows Oriental Bittersweet - an invasive vine that literally strangles trees like our beloved oaks. Artists seem to value the twisty stems, and florists love the prolific orange-clad berries for fall flower arrangements. However, left unchecked, this vine will pull down mature trees in just a few years.
Fortunately, this is an invasive plant that can be managed easily during the winter months once one knows how to identify it, and provided you have the proper chemical to apply to any cut stumps.
For those who dislike even the idea of using herbicides, I have to tell you that the alternative is to keep cutting the same plant every year. And, cutting these plants just encourages them to come back more aggressively the next year. Seriously. It is like the stories of Medusa - cut off her head, and seven new heads grew in its place. Cut one honeysuckle stem this winter, and you'll be cutting at least seven new stems next year if you don't give it a shot of herbicide.
Fortunately, herbicides will work when applied correctly in very small quantities. Since they are a poison, it is vital to wear proper protective gear and use the proper application technique to avoid harming yourself or native plants that may be growing nearby.
There is a lot of good information out there to help manage invasive plants in winter.
Friend Chris Evans coordinates an "Invasive Species" (eradication) Campaign in Illinois, and he often shares great information about best practices for recognizing and controlling invasive plants in Illinois. He posted a useful article recently that covers the basics of winter management of several of the most irritating invasive plants: Honeysuckle, Autumn Olive, Multiflora Rose, and Oriental Bittersweet. The article can be accessed here: Winter Management of Common Woody Invasive Species.
The article is on the site "Illinois Invasive Species Awareness Month," so you will find a lot of additional helpful advice about managing these pesky invaders.
“The fog comes on little cat feet” wrote Illinois poet Carl Sandburg in 1916 as he watched the fog roll in at the Lake Michigan shore in Chicago. The next line, “It sits looking over harbor and city on silent haunches and then moves on” describes the fog as it settles in for a while before retreating again.
When I first read those words in grade school, I admit that they didn’t make much of an impression. The cats I knew were like my pet Tuppence who thumped when he walked. Did fog thump? As a kid, I really didn’t know fog.
Reading the poem today, I actually experience a slight chill, for as an adult I have experienced the beauty and mystery of fog in its many forms.
For example, there is the winter fog that coats the tree branches with a thin film of ice, creating what is known as a hoar frost. This fog is a type of evaporation fog which results when cold air passes over water or warm, moist land. Evaporation increases the amount of moisture in the cool air, possibly to the point that the air can no longer hold all of the water it contains. And that is when the fog arrives.
Several years ago on a camping trip, I saw the fog roll in off the Pacific Ocean at Point Reyes California (one of the foggiest places in the world), and then watched it return to sea. This is an example of advection fog where wind blows warm moist air over a cool surface – in this case, the ocean.
Fog is essentially a cloud at or near the ground. Fog occurs when the air temperature reaches its dew point – meaning the point at which the air is nearly 100 percent saturated. Fog generally does not occur under windy conditions – the air will be calm, and any wind will be light.
In this area, the most common type of fog is known as radiation fog. On clear, calm nights, fog will form as the ground surface cools rapidly, dropping the air temperature to its dew point. This type of fog is most common in the fall and winter, and if the air is still, can last all night long, disappearing as the sun rises and the air warms.
For all its beauty, fog can be hazardous. In 1945, a B-52 airplane actually crashed into the Empire State Building in New York because of heavy fog and in 1977 two airplanes crashed on a runway in Tenerife (Canary Islands) because of limited visibility due to fog.
Fog has been blamed for fatal car accidents across the planet, in places as diverse as California, Dubai, and Tennessee. The fog not only reduces visibility, it also reduces contrast, muting everything to shades of grey, which in turn reduces one’s ability to judge distance and speed.
Fall and winter are the peak fog seasons in the Chicago metro area, including McHenry County. So, when driving in the fog, slow down, turn on the low beams, don’t pass other cars, and do not talk on the phone. It may come in on little cat feet, but don’t be fooled, that fog can be a killer!
Did anyone else notice that the President mentioned climate change during his victory speech early Wednesday morning? Specifically, he said: "We want our children to live in an America that isn't burdened by debt, that isn't weakened by inequality, that isn't threatened by the destructive power of a warming planet.”
That sounds like three priorities: reduction of the National debt, equal rights for all Americans, and doing something about climate change.
For months, I have been frustrated by the absence of a National dialogue about climate change. The topic did not come up during the Presidential debates – not even a passing reference. This, despite the fact that our own Defense Department has stated that global climate change will have national security implications for the US, as rising sea waters inundate US military bases as well as low-lying nations and as changing weather patterns cause water shortages in some countries and flooding in others.
“We will pay for [climate change] one way or another,” Gen. Anthony C. Zinni, a retired Marine and the former head of US Central Command, wrote in a report he prepared as a member of a military advisory board. His report goes on to say that America can pay dollars today to reduce its greenhouse gas emissions, or it will pay later through loss of life as the US faces more military conflicts through the political instability that climate change will cause.
So what? How does that affect us here in McHenry County? Why should we care?
Well, aside from concern about the impact to habitats and species, consider that McHenry County will have young people whose lives will be at risk in future military conflicts as nations fight over water and possibly land for their citizens. And, there is every reason to believe that the United States will continue its long tradition of welcoming refuges from throughout the world, and those people will need to have places to live. Population pressures in the US in the future will impact McHenry County, especially with our location within the Chicago metropolitan area.
I hope the next four years brings rational discussion in the US aimed at taking meaningful action to address climate change and to reduce the risks of future global instability that will result if nothing is done. Let’s not push this problem off onto a future generation.
