kickapoo valley reserve
The KVR has the first ever Drive-By Lichen Viewing Site! Yes, you now can see lichens without even getting out of your car. I do not recommend this, but if it’s raining, it’s ok to roll down the windows and take a quick look, then come back later and walk around.
The official name of this site is “Cut Off and County P” lichen site. It is located east of Highway 131 and Bridge 10, on County P at the intersection of Cut Off Road. There are no markers at this site, as it is on the road right of way, but it is easy to get to and hard to miss. Once you are here, please do get out and walk around. Check the details of this site and the lichens living here by going to the Lichen Site tab on the main page.
There are several special aspects to this site. The first is the easy access. There are numerous places to search for lichens in the immediate area as well as right on the roadside cliffs.
Secondly, the cliffs on each side of the road are directly exposed to the chemicals and poisons expelled in our car exhaust as we drive through the narrow channel made by the rock walls. This may be the site most affected by air pollution on the reserve. Another interesting aspect of this site is that one cliff faces north and one faces south. The north facing cliff gets almost no direct sunlight, and is black in color.
The south facing cliff is in full sun all year long and shows the usual brown colors of sandstone. Each surface has a different mix of plants, lichens, and fungi. Throughout the year the populations of each change in size, color and quantity.
Most of the lichens at this site are crustose type, but there are also several foliose species here. If you search the nearby trees and some of the cliffs farther back in the forest, you may find some fruticose lichens too. Usually fruticose lichens are more sensitive to air pollution so if you find any of that type of lichen at this roadside site, please let us know, and take a picture of it for our records.
How many different crustose lichen can you see on each cliff face? What lichens are only on one cliff face and not the other cliff? This is an easy site to visit periodically. When you come back, are there different colors on the rocks? Can you find more lichens or less, than the last time you looked? Send your observations to the Lichen Project, and be part of Citizen Science explorations!
Thanks for visiting the KVR Lichen Project. Come visit us in Lichen Land!
Here in Lichen Land, the tiny but vast community of lichens, bryophytes and fungi are having a party on the Wintergreen Trail. Cladonia and Peltigera, Stereocaulon and Candelariella, Xanthoparmelia and a small crowd of their crustose friends are sporting fancy apothecia (disc or cup that produces spores) in many shapes and colors. The place is decorated in the brightest colors-turquoise, jade green, yellow, white, black, gray, brown, rust, pale blue. A Cladonia first caught my eye; she was fringed and spangled with intricate weavings of pale green, crowned with a russet apothecia/cap perched on her tall slender podetia (stalk). Many other Cladonias waved jade colored cups, some fringed and some smooth edged. The Peltigera rufescens, that not long ago sported velvety gray thallus and dramatic, hooded, vase-like apothecia, now were a bit faded in places. But some of them had grown dozens of tiny, white rhizines (root like structures) from the underside of the thallus (the vegetative part of a lichen that contains the photobiant and mycobiont.
All this elaborate activity goes on within one inch of the ground. A wrong step by a human would destroy many years of growth. But you can join the party; pack a 6x or 10x hand lens, your camera, and just walk into Lichen Site 4. They’ll all be there. Once you step down the two stone steps and turn right, slow down. Stop. Take out the hand lens. Breathe and relax. Even though it’s a party down there, we need to slow down to join up with the Tiny Ones.
Have you ever hunted for 4-leaf clovers? Use the same type of gaze and attitude; you’ll be more successful with lichens because there are so many of them, you can’t miss them. Once a few are seen on the pine needle covered ground you will start to see the stalk-like podetia everywhere. Get down close to them, use your hand lens held close to your eye, then move closer or farther from the lichen to focus, keeping the lens close to your eye.
At ground level the elaborate, fringed structures make a fairyland scene. A few weeks ago, the podetia were straight and smooth pointed stalks. Now they sport cups, caps and fringes. The thallus (the leafy part) may have rhizines, brighter color and also more elaborate shapes. There are many very tiny lichen growing among the taller ones so be careful where you step! It truly is a forest in miniature, with a canopy, mid layer and ground layer of plants and animals.
There are several types and species of lichen sharing Cladonia’s forest. Peltigera sp. has been introduced earlier, but there are many more lichen here. On the edge of the narrow pathway, rocks with lichens barely discernible in the summer now are alive with color and texture. These are crustose lichens, and there are quite a few species here. Many
species of crustose lichen on the rocks at this site have produced apothecia. Look for dark spots in the light colored crustose lichen body. Most of the lichen on these rocks are white, gray, or blue-gray. There also are some black crustose lichen here. Look closely with your hand lens to check for apothecia on the black lichen; they are hard to see. How many different species of lichen can you find? These can be very hard to identify without a high powered microscope to see details, and chemicals to test certain reactions lichens may have. At this time, the Lichen Hunters are simply recognizing these are ‘crustose’ forms.
On the low, sandy cliff (the cliff is 2-3 feet high) at the top of this area, the walls have been decorated in turquoise, green and white. The colors are bright and clear. In the shadows under the rocky overhang, the gauzy, lacy texture of lichen mixed with moss, spider webs and falling grains of sand make a confusing scene. What is lichen, and what is sand grains, or spider webs?
As the sunbeams illuminated strands of turquoise and green against the dark recesses it seemed to be an endless mass of tangled threads. Much of the lichen here is probably a Stereocaulon sp. commonly called ‘Rock Foam’. There are several species, some of which, in the arctic, are food for caribou during famine.
Pixie Foam, a miniature Stereocaulon species, often grows where there is a high concentration of metals in the rock. Lichens are used all over the world to prospect for minerals by analyzing the mineral content of the lichen thallus. (From ‘Lichens of the North Woods).
How many species of lichens can you sort out, under the sandy ledge? There are also mosses, ferns and fungi here. How many different life forms can you find, of any kind? This is a rich, active place, yet we know almost nothing about the lives here, or what their place in the world might be.
This visit to Lichen Land left me feeling as if I’d crashed a party. The last time I was here, the lichen were growing podetia but were much smaller. Today I crossed the threshold of two stone steps into their world, and it had changed dramatically. Colors were brilliant, forms were elaborate; the lichens seemed more alive! They didn’t seem like the same lichens I’d seen earlier. It was quiet, but I felt there was music and shouting and dancing going on, in a tiny way. It felt like a party.
As I walked away I thought about how the earth, rock, sand, and trees, each have a community of lichen. They are not plants, they are not animals; they are simply something else. What do they weave for the web of life in the world as we know it? Why do they cover such a large part of the earth’s land surface? There are over a hundred species of lichens on the base of the trees in the Kickapoo Valley Reserve. We don’t know how many different ones are in the canopy, or the soil or on the rocks here. Everything in Nature has a place and a purpose. The Lichen Hunters are exploring what that might be for the lichens in the Kickapoo. Come on out for a walk in the woods and help us learn about the Tiny Ones.
We may be hearing a lot more in the future about mycorrhizal fungus. This site is an ongoing story about lichen, and officially, mycorrhizal fungi are not really ‘cousins’ of lichens. But cousins are often the most numerous relatives we have, so I use that term to foster awareness that the fungus Kingdom is varied and vast. Sometimes getting to know one member of a family entails getting to know other members of the family one had not planned on meeting, or even knew existed. At the party called Daily Life on Earth, meeting all the relatives is part of the fun.
I met a mycorrhizal fungus last fall, on a dead tree trunk at the end of the Wintergreen Trail. I believe it is hyphae but do not know the fungus species. If anyone reading this knows, please post your ideas! Even deceased, it was an impressive presence. Long dark threads hung from the leaning tree trunk where the dry bark had separated from the inner wood. The threads formed a complex web several feet long, dangling in the air. The strands were so strong I could not break them by hand. There was yards and yards of this fibrous material. It seemed to have covered most of the surface of the tree trunk, under the bark.
Fiber strings from under tree bark
The picture is blurry, but the very dark strings and dark bark had no noticeable detail, so the picture is close to what I saw. The extent of the fiber mass was impressive.
Why am I talking about this mat of dark threads? Because I was exploring the NASA Global Climate Change site and found a story on mapping the mycorrhizae locations in forests, by mycorrhizae species. Read the story for why NASA is doing this; it’s interesting. There are two mycorrhizal species and trees use one or the other. The forests are regulated by the signals the mycorrhizae send through the trees. They work with other plants too. Scientists think this is important enough to make maps of where each species is in the forest, in relation to the tree species, and they are doing so by satellite images. So that old adage “you can’t see the forest for the trees” is true for us in a much deeper way than we ever understood before. The trees are one part of a vast and complex web of living beings, all talking to each other and cooperating to regulate themselves and their environment. Once we lift the curtain of our preconceptions, amazing things start to show up everywhere. If we only see trees, birds and some flowers, we are missing the major part of the forest. There is far more diversity and number of living beings in and under the soil than above it, and as much metabolic function occurs on and in the ground as above. The Small Ones may be at least as interesting as the large plants and animals we easily recognize.
After reading the article and thinking again about the mycorrhizae, I wonder about the relationships between fungus that don’t make lichen and those that do; between the chemistry created by one group of trees and fungus, and the signals of moisture, temperature, nutrients and more that may be allowing or encouraging certain other living beings to take up residence nearby. We know so little about the extensive activity going on just underground. What similar actions may the lichen be doing? After bacteria, they are the original homesteaders, setting up the terrain to be hospitable to the first mosses and vascular plants. Lichen are very good at getting along with other life forms and have made a place for themselves everywhere on earth. Maybe they have something to tell us about their part in regulating the forest, beyond their original activity of creating soil and available nutrients from rock and wood and air.
So, no lichen pictures today, just questions about this green and shining world we share with unknown others.
Check this blog again soon, for information on our first KVR lichen survey route.
Julie, Olga and I went out to view the white and wonderful woods after the big snow a couple days ago, and I, of course, had a secret agenda to also check on the Little Ones. As soon as the new snow warmed slightly the snow fleas were out hopping around. I knew the lichen would not be hopping around! But they do show their colors in the snow and I am still searching for new species. Each day in the forest brings the possibility of meeting a new lichen (as well as whatever other wonders appear whenever one stays in the woods a while). We are walking on Cutoff Trail. The ice has formed curtains along the rock walls, as it has almost everywhere this year.
No ice caves here, just a small cliff. The rock is mostly covered with liverwort, moss, fern; the lichen are small. One of my favorite trees, the river birch with its beautiful coppery bark, stands here.
The lichen like this tree too; the moist base has a colony of aqua blue lichen. Aren’t they beautiful on the red and silver bark? Since the names are not verified yet, I can describe them any way I wish, in this blog anyway! Don’t worry, names will be forthcoming by spring.
Turkeys flapped around in the treetops. The sun came out. On the south slope, snow in the branches began to melt, just enough to form liquid water at the edges of the snow on each branch. The trees were suddenly illuminated in diamonds of light. A few moments later as we walked away from the direct sunshine, the warming air simply made the clumps of snow in the branches fall off on our heads.
This is not a lichen, it is a fungus, making a little snow sculpture on the side of a tree.
While we move about so quickly and ceaselessly, the trees, moss, rocks and lichen quietly remain. The ice moves too. More slowly than us but faster than lichen, rock or tree; changing all those slow moving ones as it forms, grows and then disappears. The lichen and their rocks and trees will be here as we and the ice come and go.
Remember to enjoy the small things in life.
Remember this, from a week ago? A little frosty but still green and growing.
Today, January 10th, it was 5 degrees above zero and this is my lichen hunting outfit; every layer of Canadian ski clothes I can find:
And here’s Lichen Land now:
But as we know, the lichen are quietly waiting for the ice to melt. Meanwhile the ice is busy make beautiful patterns. I wonder what it looks like from underneath, where the lichens are?
Since it was so cold today, I went out to see what the lichens looked like on the hill behind our house. As I searched for them in the ice and snow I thought about how quickly they exchange their active life for dormancy. Another warm day and these ice covered lichen will be back to life in a few hours.
Below: very cold lichen
It’s fun to see what else is out in the woods besides the lichen.
This is the hilltop where these pictures were taken:
It’s a busy place. See all the tracks? Our coyote friends like to gather in this area and sing to us. Their tracks tell the story of what they do while here.

At the top of the ridge a dead tree trunk supported these fungus
After an hour there seemed to be more and more snow and less lichens, and it was getting colder so I went home. I went less than a quarter mile from the house and had a good adventure. What’s close to home where you live? If you’re out there and meet your own resident lichens, share them with us!
