Suburban Wildlife Magazine: IRJM Photo Essay: Wadsworth Savanna Sunrise






IRJM has contributed previous ideas to this blog magazine. She has agreed to edit, choose, or contribute to this feature, known as IRJM Photo Essay.



A morning hike through Wadsworth Savanna Forest Preserve provided morning scenes of wetlands, savannas, prairies, and woodlands.

Birds, deer, and spring flowers were met along the trail.











The sunrise coming over the top of the trees that lined the Des Plaines River, however, provided the most memorable photo of the trip.


Until next time. And remember to stay on the trail.






Suburban Wildlife Magazine: Des Plaines River Trail 18: Wildlife and Wetlands at Wadsworth Savanna














I continue my quest to hike the entire Des Plaines River Trail through Lake County, Illinois. I began this 31 mile trail at Lake-Cook Road in September of last year. Along the way, I met hikers, bikers, and horseback riders. I saw the seasons change and learned much about the area's wildlife and prairie history.

Each time I drive past the Des Plaines River near my home since that first Des Plaines River Trail hike, I feel a connection to this wonderful trail that has introduced me to Lake County's suburban wilderness.

Restored prairies and woodlands have been cared for by professionals and watched over by volunteers. The settlement history of the Illinois prairie has stamped itself along the trail, giving us the legacy that is present today.

It was with much excitement that I rolled out of bed early on a mid May Saturday morning and headed north to Wadsworth Savanna Forest Preserve. I had last hiked the Des Plaines River Trail in early February when the trail was covered in ice and snow.









The prairie veiw that met me at sunrise was spectacular. The sun was just coming up and I was greeted by a restored wetlands pond. A slight breeze brushed past me as I proceded onward. Ducks, geese, and redwing blackbirds were all around.









Redwing blackbirds called out to me and flashed their brilliant red shoulders in my direction. They were quite close to the trail. I paused and watched one balance on a single cattail stem. Suspended on the cattail's stem, the bird did not rest, but chattered at me until I ambled away.







 


The Des Plaines River Trail winds through this restored wetland area. This preserve site also serves as an an outdoor wetland laboratory (more on that later).






Soon after, I found the trail and headed north and crossed Wadsworth Road. A shallow pond to my left caught the reflection of a solitary Canadian goose paddling in the water. Its graceful motions in the water reminded me of a small boat floating along the surface.








I passed a cattail marsh to my left and glimpsed the Des Plaines River to my right. The sun glittered through the trees along the river's banks. Just to the east, I heard the rumble of a cargo train. Trains have been passing by this prairie site for over 140 years! The wildlife animals must be used to the noise by now.
 
Today, the main color of the prairie wetland site was multiple shades of green. The morning sun's rays created highlights and shadows along the trail. A fresh clean scent was in the air.










Ahead, the trail made a gentle climb. In the distance, I saw an oak savanna. I remembered last July going on a night time bat hike  on this trail. That night time hike was with the Lake County Forest Preserve. It was in this savanna that we encountered several bat species.  

Bats have a huge appetite for wetland and woodland insects. At night, they will fly out from the tree tops and swoop over the grassy wetlands for a meal.

I had not been back to this location since that time, and I enjoyed seeing the day time version of this forest preserve trail. Today, the bats were safely tucked away, somewhere in the forest trees above me and waiting for their wake up call tonite.








The prairie fields on the left and my right had many spring flowers blooming, including several patches of white and pink colored shooting stars.










This restored prairie and wetland site contributes to the overall health and diversity of plants and animal in this preserve's location. As I left the shade of the oak savanna, I surprised a deer grazing in a clearing to my right, near the Des Plaines River. It did not appreciate my presence, and with a wave of its white undertail, leaped into the nearby woodlands.

Further on the trail were many more wetland and prairie land flowers. I also observed a patch of common milkweed plants. Their leaves were rolled up as they pushed up from the earth. Within a few days, the leaves would be fully opened and in operation.









The trail continued along a wetland portion of the preserve. A great grey heron flew above me, following the savanna north. Their majestic flight is always a treat to see up close.

A killdeer was bopping and sprinting on the trail ahead of me. It stayed just in front of me as I would get closer to it. The bird then ducked into some grassy brush and hid from me.









I spied a clump of yellow flowers. The petals were arranged in a spiral. When viewed from above, they looked like a pinwheel. This was a patch of Canadian lousewort, also known as a beefsteak plant, wood betony, or (I like this name) snaffles.

I was happy to identify it and check out its unique floral pattern. The leaves have a fern like pattern to them. Native Americans ate this plant much like we eat spinach today.









This preserve's wetlands have been organized by several local, state, and federal programs. The benefits of wetland restoration have allowed Wadsworth Savanna Forest Preserve to be a living laboratory. Field studies are actively conducted. Plant and animal diversity observations are showing that the restoration process is proceeding quite well in this area.

Wetland benefits to the river basin include water table storage, cleansing of non-point source pollution, and flood control.









Historically, the Wadsworth area was not amenable to easy agricultural conversion. The soil is a mixture of clay, mud, and "muck" which was not easy to farm. Meadow potholes, effects from retreating glacial activity 12,000 to 14,000 years ago, further inhibited initial settlement of this area.

The completion of a railroad line from Chicago to Milwaukee along the Des Plaines River in 1873 brought increased settlement oportunities to this site.

In 1874, a local farmer, John Lux, platted a village as a stop along the Chicago, Milwaukee & St. Paul Railroad, in an effort to increase the land's value. This village stop became present day Wadsworth, Illinois. It was named for one of the major stockholders of the railroad line. 

This village continues to take pride in its rural flavor, using the motto: "the village of country living".










As I hiked further on, I continued to observe large numbers of birds in the wetland and praire portions of the preserve. Red winged black birds were most numerous and vocal, but robins, warblers, and Canadian geese were also plentiful.










After reaching this hike's endpoint at West Kelly Road and Skokie Highway (Route 41), I stopped and took in the surroundings. A convenient restroom facility was handy, as was parking for the next visit. I reversed my steps, happy with the day's adventure. I saw milemarker 4 on today's hike, and know that the Wisconsin border is getting very close. 

It will be bittersweet to complete the Des Plaines River Trail over the next few hikes. I have enjoyed the journey and what it has taught me about the prairie.

Until next time. And remember to stay on the trail.











Suburban Wildlife Magazine: Why Has The White Trillium Turned Purple?


 





 




On a recent return hike through Reed-Turner Woodland, I noticed that the white trillium petals were now turning purple and shriveling up.

I had enjoyed watching the white petals carpet the woodland floor, and in just two weeks, the flowers had run their course.

It made me wonder: why are the petals changing color, and how does this happen?







 


Some flower species, including white trillium, are able to change their petals' color after pollination. This process is called floral color change.









White trillium do not self pollinate. The plant must attract insect pollinators to its flower so that pollen may be transferred to another plant for fertilization to occur.

Nectar and pollen are rewards given to the insect once it lands on the flower. However, the production of nectar and pollen require energy by the plant.

After pollination occurs, the plant no longer needs to put energy into producing pollen or nectar. Instead, the plant directs its energy stores to the fertilized products.











Metabolic changes after pollination alter the pigments expressed in the plants' petals. The new pigments change the petal's colors. Pollen and nectar production rates are also lowered after pollination.

These changes are a signal to the insect pollinators that they need no longer land on the pollinated flower. The insect pollinators will go on to another flower that has not undergone fertilization.

The interaction between plants and animals and their ability to give each other signals is an ongoing natural wonder.

So the next time I see a white trillium turning purple, I will know that the life cycle of that plant is on track.

Until next time. And remember to stay on the trail.









Suburban Wildlife Magazine: Shooting Stars and a "Buzz" on the Prairie







A Shooting star flower on the prairie.




A recent hike at Wadsworth Savanna Forest Preserve in Lake County was a visual treat for one of Illinois' most showy and interesting native prairie flowers: Shooting Star.

In the Primrose family, this herbaceous perennial blooms in May. Its petals are white or light to rosy pink in color. The plant requires 2-3 years of growth before its first bloom occurs.






Shooting star and its long stem.




Its habitats include dry black soil prairies, limestone glades, bluffs, slopes, fens, and abandoned fields. 

Native Americans used the flowers as a source for dyes to fibers and wood. Early pioneers called this plant the Prairie Pointer. Other common names include: American cowslip, mosquito bills, mad violets, and sailor caps.





Shooting star, a nodding flower.




Most striking, however, is the way the flower is arranged: it is in the form of a "nodding flower". The sepals are bent backward and the stamens are thrust outward. The pollen of shooting star plants is fine grained and firmly attached to the anther at the end of the stamen. 

Wind is unable to dislodge pollen from the anther. In order for the pollen to be released and reach the plant's stigma for fertilization, bees are required. They do this in a special way known as buzz pollination or sonication.





Light pink blooms of a shooting star color the prairie.



Bumblebees are especially adept at freeing the pollen from the stamen by the following technique: the bee hangs upside down and grasps the base of the stamen. They selectively vibrate their thoracic muscles in a rapid manner, but do not activate their flight muscles. (Think of how you move a salt shaker to release salt onto your food.)

At a particular frequency, the vibration (the "buzz") against the stamen causes the pollen to be released from the stamen's anther. The pollen, now free, attaches to the bee's body. At the next stop onto another shooting star flower, the pollen may be deposited onto the stigma and allow fertilization to occur. 

Though queen bumblebees are the plant's main pollinator, other bee types that may visit and pollinate shooting stars in this manner include Green Metallic bees, Eucerine Miner bees, and Anthophorine bees.

Once fertilized, the seeds develop and are dispersed by the wind. 






A wind dispersal pattern of shooting star is noted on a prairie view.



 
Buzz pollination also occurs in eggplants, potatoes, tomatoes, blueberries, and cranberries. A specialized tool, known as the electric bee pollinator, has been created for commercial growers to "buzz" pollinate their green house plants.

So the next time you see a shooting star out on the prairie, or shake salt onto a tomato or potato, think of the "buzz" of a bee.


Until next time. And remember to stay on the trail.





Suburban Wildlife Magazine: Interview with a Wildlife Expert: Reed McCool





"I always wanted to grow up on a lake and be in nature."
-Reed McCool, outdoor enthusiast and recreational fisherman.










Many outdoor enthusiasts and professional wildlife experts began their outdoor adventures at a young age. These individuals were often mentored and encouraged by others to appreciate wildlife and the outdoors. As they spend more time outside in the woods, a lifelong passion for the outdoors develops.

Often, such individuals continue their interest in the outdoors, eventually working as environmental advocates or pursuing wildlife related careers. 








With these thoughts in mind, I asked my nephew, Reed, for a "Wildlife Expert Interview". He has developed a strong interest in the outdoors, and as you will see in the article, he is truly worthy of the title "wildlife expert".
 

Reed is just short of his 16th birthday. He is an avid outdoor enthusiast and a self-taught recreational fisherman. He was kind enough to talk to me about his experiences in the outdoors and to teach me a few things he has learned along the way.








How did you get started in fishing and the outdoors?

"I was pretty young...my Dad and I (first) went fishing when I was 3 or 4 years old", he answered. "I also visited my Grandpa Larry in Kentucky and fished from the dock and his boat at around the same time."

"My other Grandpa, John, lived next to a forest preserve (in Illinois), and I would walk the forest" with him. "I would watch everything."

Reed remembers at age 6 or 7, he began to wade in the river and fish with his Grandpa John. He spent more time exploring the outdoors and fishing with his friends and his Dad (my brother Mike).










Now I can remember my brother Mike telling me that Reed spent hours studying the water from the shore to catch fish. Reed would figure out, on his own, how to catch bigger fish. 

Mike told me that Reed consistently brought home bigger bass and catfish. These fish would put what Mike and I caught as kids to shame. Where Mike and I would seek bragging rights by the ounce from our childhood catches, Reed was talking pounds! (Reed shares some of his secrets below.)

Reed told me he spent a lot of his time outdoors fishing and camping. He would sleep outdoors in the backyard in a sleeping bag with his friends or his Dad. He would use no tent, so as to sleep under the stars. His interest in the outdoors and fishing continued to grow.









What do you like best about fishing?

"When I fish, I prefer being by myself or with my best friend", he answered. "I like to fish and explore and to catch what (fish) we can."

He further adds that he enjoys "being able to do what I want; the freedom to catch a fish" and "being outdoors without any limits."


What type of fishing do you prefer?

Reed told me he prefers to fish from the shore or a canoe in a nearby lake. He also wades in the DuPage River to fly fish.









What type of fish and bait do you use?

For bass, he uses a crank bait. For catfish, Reed makes his own bait. He puts meat into a ziplock baggie until it spoils. He then uses the rotten meat to get the bigger catfish. He has "10 or 11 tackle boxes", saving his own money from odd jobs to pay for the lures and equipment.









How does he catch the bigger bass?

(Reed holds the McCool family record for this category, so I listened closely for his answer.) He told me he fishes first for a 3 inch bluegill on a small hook. Once he catches one, he puts the bluegill on a larger hook to attract the bigger game fish. He told me the bigger the bluegill, the bigger the bass he catches! He has many stories of catching 5 and 6 lb bass from this method.










How do you read the lake from the shore for fish?

Reed explained that catfish prefer the deep, dark areas of the lake. They often feed by burrowing in the lake's bottom which makes the water murky from this activity. He looks for these murky areas in the lake and sends his bait into those locations with good success.


Do you have any unusual fish stories to tell?

"I once caught a huge alligator snapping turtle on a spinner bait. I had to cut the line to let it go. I had a video of it on my cell phone."

"Another time, I was fishing with my Dad and I caught two fish on a single lure." Reed told me that two 14 inch bass had each taken a separate hook on the same lure at the same time!

 








What are your future dreams for the outdoors?

"I always wanted to live near a lake or near nature in a cottage." He added that it was "just what I like."


Have you seen any effects of man on your outdoor adventures?

Reed told me that algae killer is periodically put into ponds and the lake near his home where he fishes. "This also kills many fish", he said.

He also notes that for years, his Grandpa John would feed deer by hand in his backyard. Several years ago, Reed remembers that deer were culled from the adjacent forest preserve (120 in number per John). He notes that his grandfather has had no recent deer to feed since that time.










I thanked Reed for his time, and look forward to watching his interest in fishing and the outdoors continue. I also took notes on his tips in getting a bigger fish!

Until next time. And remember to stay on the trail.





Suburban Wildlife Magazine: Telling the Boys from the Girls




As an obstetrician, I am well acquainted with announcing "boy" or "girl" at the delivery. It is a fun and special time to be the referee and make "the call" when the couple does not know the sex of the baby ahead of time.
 
When it comes to plants, however, the rules are different, and it is a good idea to check the playbook before making "the call". Such was the case when I encountered Jack (or Jackie)-in- the-Pulpit plants.

These plants have the option of being a boy or a girl and then changing their mind. Like any referee, once you know the playbook rules, it becomes easy to tell the boys from the girls!










I had recently hiked through Reed-Turner Woodland in Long Grove, Illinois. There, I encountered numerous Jack-in-the-Pulpit plants along the sides of the trail and in the understory of the forest.

Jack-in-the-Pulpit is a herbaceous perennial found in moist to dry deciduous woodland forests, bottomlands, swamps, and bogs in North America. It begins to flower in May.

Its unique appearance is due to the spathe (the pulpit) which overlaps and covers the spadix (the jack). Common names include Pepper Turnip, Marsh Pepper, Bog Onion and Cuckoo Flower.










Individual plants may live up to 100 years. The plant contains calcuim oxalate that gives it a bitter taste. Raw, it is also poisonous to humans.

More interesting, however, is that an individual plant can change its own sex from year to year! This is one of the few plants in nature that has this ability.






So just how does a jack-in-the-pulpit determine its sex? And how can a casual hiker tell the difference between a Jack or a Jackie?

It turns out that the answer is easy. Whether the plant chooses to be male or female in any given year is determined by several factors: its age, the availability of water and nutrients, the plant's leaf health, and root storage. All these are conditions that are reflective of the plant's preceding growing season.









The plant's underground root structure is called a corm. If the corm is older (5 years or more), receives adequate water and nutrients, and food production from healthy leaves, the resulting corm becomes large. Large corms are needed to produce seeds. The more that a corm can store, the more the stored energy can be used in seed production.

When the corm reaches a critical size to allow energy for seed production, the plant will produce female parts at the base of the spadix in the subsequent growing season. The female flower parts are small, and look like tiny green berries when viewed with a magnifying lens.The female plant will also produce two trifoliate (three part) leaves to enhance food production from photosynthesis.

So, to identify a female Jack-in-the-pulpit (a Jackie) in the spring time, look for green berry like parts at the base of the spadix and two trifoliate leaves ("its a girl!). Since handling flowers in forest preserves is not permitted, just look for the two leaves instead, and don't peak under the spathe. Keep Jackie modest!









In late summer and in early fall, only female plants will have the characteristic red berry cluster. After producing berries and seeds, the corm becomes smaller, and the plant may be a male in the following spring season.










A male plant develops when less energy is stored in the corm. This occurs in younger plants (2-5 years), those that have had their leaves munched on by insects or deer, and in dry or low nutrient conditions. In the next growing season, the plant will develop male parts. Under magnification, these appear as small thread like structures with tiny yellow to brown anthers at the base of the spadix. Addtionally, male plants grow a single trifoliate leaf.









As a reminder, while viewing plants in the forest preserves, don't pull the spathe up to view the base of the spadix - Jack may want some modesty, too! Just look for Jack-in-the-pulpits that have a single three pronged leaf!









An individual Jack-in-the-pulpit plant cannot fertilize itself. Fertilization is accomplished by fungus gnats which are attracted to the plants' emmission of a fungus-like odor. When the gnat wanders into the bottom of the spathe and near the base of the spadix in a male plant, pollen is transferred onto the gnat's body. As the gnat travels into the spathe of a female plant, pollen may be deposited at the base of the spadix. Fertilization may now occur.











The seeds develop in a cluster of red berries. Birds then eat the berries and disperse the seeds throughout the woodland floor. Successful seedlings take at least three years to produce their first flower (usually as a male plant).












So there you have it!

Look at the photos in this article. Can you tell the boys from the girls? Good luck!











Here are a few quotes from famous Jacks (and a Jackie), in no particlular order:


Don't be too proud to take lessons. I'm not. -Jack Nicklaus


When you're riding in a time machine way far into the future, don't stick your elbow out the window, or it'll turn into a fossil. -Deep Thoughts by Jack Handy


It's amazing the little things you can use, like one of my flowers out there [in the backyard]. He would dry a leaf and use it for a model. -Jackie Kennedy


One day I will find the right words, and they will be simple. -Jack Kerouac


The function of man is to live, not to exist. -Jack London


One last drink, please.  -Jack Daniel


You must never underestimate the power of the eyebrow. -Jack Black

The world is the true classroom. The most rewarding and important type of learning is through experience, seeing something with our own eyes. -Jack Hanna

Suburban Wildlife Magazine: More about Mrs. May Theilgaard Watts





Naturalist. Teacher. Poet. Writer. Artist.
 

These are all descriptions of Mrs. May Theilgaard Watts. Her prairie contributions and life story may be viewed at:

May Theilgaard Watts: "Every Landscape Tells a Story"


Through additional research, I have discovered Mrs. Watts' Chicago Tribune editorial. This was a monumental letter in her illustrious career, and launched her lasting outdoor legacy: the Illinois Prairie Path.




Mrs. Watts' editorial, dated September 25, 1963 follows:

We are human beings. We are able to walk upright on two feet. We need a footpath. Right now there is a chance for Chicago and its suburbs to have a footpath, a long one.

The right-of-way of the Aurora electric road lies waiting. If we have courage and foresight, such as made possible the Long Trail in Vermont and the Appalachian Trail from Maine to Georgia, and the network of public footpaths in Britain, then we can create from this strip a proud resource.

Look ahead some years into the future. Imagine yourself going for a walk on an autumn day. Choose some part of the famed Illinois footpath. Where the highway crosses it, you enter over a stile. The path lies ahead, curving around a hawthorn tree, then proceeding under the shade of a forest of sugar maple trees, dipping into a hollow with ferns, then skirting a thicket of wild plum, to straighten out for a long stretch of prairie, tall grass prairie, with big blue stem and blazing star and silphium and goldenrod.

You must go over a stile again, to cross a highway to another stile. This section is different. The grass is cut and garden flowers bloom in great beds. This part, you may learn, is maintained by the Chicago Horticultural Society. Beyond the garden you enter a forest again, maintained by the Morton Arboretum. At its edge begins a long stretch of water with mud banks, maintained for water birds and waders, by the Chicago Ornithological Society. You notice an abundance of red-fruited shrubs. The birds have the Audubon Societies to thank for those. You rest on one of the stout benches provided by the Prairie Club, beside a thicket of wild crab apple trees planted by the Garden Club of Illinois.

Then you walk through prairie again. Four Boy Scouts pass. They are hiking the entire length of the trail. This fulfills a requirement for some merit badge. A troop of Scouts is planting acorns in a grove of cottonwood trees. Most of the time you find yourself in prairie or woodland of native Illinois plants. These stretches of trail need little or no upkeep. You come to one stretch, a long stretch, where nothing at all has been done. But university students are identifying and listing plants. The University of Chicago ecology department is in charge of this strip. They are watching to see what time and nature will do.

You catch occasional glimpses of bicycles flying past, along one side. The bicycles entered through a special stile admitting them to the bicycle strip. They cannot enter the path where you walk, but they can ride far and fast without being endangered by cars, and without endangering those who walk.

That is all in the future, the possible future. Right now the right-of-way lies waiting, and many hands are itching for it. Many bulldozers are drooling.

-MAY THEILGAARD WATTS, letter to the editor, Chicago Tribune, September 25, 1963.




I also received permission to publish the following photo of Mrs. Watts, courtesy of  The Special Collections Research Center, University of Chicago Library.

Carol Doty, retired librarian and historian at The Morton Arboretum, knew Mrs. Watts and describes her as a "tall, extraordinary woman with a presence, who had a wonderful laugh". Her greatest secret, according to Carol, was how "Mrs. Watts could make everything a story in an interesting way".

I have enjoyed learning about Mrs. Watts and reading her books on natural history and ecology. An additional pleasure has been meeting people who knew her personally, and can share her outlook in a first-hand manner.

I encourage you to explore the Illinois Prarie Path, and to discover Mrs. Watts' enthusiasm for the outdoors by reading her books. You will not be disappointed!

Until next time. And remember to stay on the trail.

Again, acknowlegements must go to Ms. Carol Doty, retired historian/librarian, The Morton Arboretum.



 


Suburban Wildlife Magazine: IRJM Photo Essay: Half Day Forest Preserve Spring View





IRJM has contributed previous ideas to this blog magazine. She has agreed to edit, choose, or contribute to this feature, known as IRJM Photo Essay.






Spring has arrived and the month of May continues to be a great time to get outside and check out the sights and sounds and smells of the outdoors!

I had a recent opportunity to stretch my legs on a trail at Half Day Forest Preserve. The sunshine highlighted the white puffy clouds over my head as I took in the views before me. A Baltimore oriole greeted us from a treetop and Canadian geese were paired by their nests.

This photo says more about the day than I can find further words to write. So enjoy the view.

Suburban Wildlife Magazine: Look For, But Don't Pick the Trillium

 


As the prairie wakes up for spring, trillium begin to carpet the woodland floor. A spring ephemeral, trillium is in the lily family and is comprised of nearly 50 species. It's tendency to be one of the first spring flowers gives rise to the nickname: wake robin. Other nicknames of trillium include birth root, ground lily, coughroot, snakebite, and (my favorite) Stinking Benjamin.

The various names for trillium give us modern hikers clues as to what treatments or ailments this woodland herb may have been used for by Native Americans, pioneers, and herbalists.






White trillium, an early spring flower of the prairie woodlands.





Botanic features of trillium include an underground rhizome from which arises an extended stem known as a peduncle or scape. Three leaf-like structures known as bracts arise symmetrically from the stem, after which follow the three symmetric flowers. The length of stem from the bracts to the flowers varies from species to species. The flower petals may be immediately adjacent to the bracts or several centimeters removed.

An individual plant may require more than 12 years to make its first flower! Because of this, and for the reasons noted below, plucking this plant's flower is discouraged.






Prairie trillium, a purple flower of the spring woodlands.



On recent hikes, I encountered two trillium species: the larger white trillium (Trillium grandiflorum) and the purple colored prairie trillium (Trillium recurvatum). Patches of white trillium were more common in the woodlands I visited. The white trillium are easier to see than the purple prairie trillium. In one site at Ryerson Forest Preserve, I even found both species of trillium adjacent to each other.






Note the extended pedicle length from the bracts to the flower of white trillium.




The rhizome-stem structure of trillium is such, that if the flowers and bracts are picked, the plant will die. The plant's actual leaves are normally wrapped around the underground rhizomes; if the bracts are removed with the flower, there are no functional leaves for the plant to survive.

In states and counties where rare trillium species are endangered, they are protected by law. Local customs also discourage picking the flowers and bracts of this plant.






The purple flower of prairie trillium is nearly adjacent on the pedicle attachments
of the bracts.




Deer, however, don't follow laws or customs, and will go out of their way to find the flowers and bracts of trillium to munch on. Wildlife studies report a reverse correlation of the height of trillium plants to the density of deer in a woodland site. In other words, the shorter the average trillium height, the denser the deer population in a given area.






Trillium prefer woodland areas under tree cover.
 



Trillium populate woodlands and fenced areas under partly shaded trees, including oak, hickory, and maple. This perennial plant is also popular with North American gardners.






Adjacent species: prairie trillium and white trillium at Ryerson Woods Forest Preserve.



A variety of trillium species may populate a given woodland area. The species' flowers may vary in color and stem length. White trillium changes its colors from white to pink over a single growing season. The purple color of the prairie trillium may hide the plant from being seen by grazing deer.





A close up veiw of the purple prairie trillium flower.



Seed dispersal of trillium is primarily by ants. This is known as myrmecochory. The seeds have a soft, fleshy organ attachment called an elaiosome. The elaiosome contains lipids and nutrients. Trillium seeds also release an odor (remember Stinking Benjamin?) that attract ants.

Ants carry the seeds and the attached elaiosomes back to their nest. They eat the elaiosome and discard the smelly seed on their nest's garbage pile. It is there that the trillium seed germinates and grows into a plant.





Ants seek the trillium flower.




Studies show that seventy meters (231 feet) is the maximum distance that ant dispersal can transfer seeds in a woodland setting. This short distance is not enough to explain how trillium has covered the extent of prairie woodlands, for which it exists, since the retreat of the last glacial age 10,000-14,000 years ago. Other animals have been identified as secondary seed dispersal vectors for trillium, including Vespid wasps and deer. 

Vespid wasps have been shown to disperse seeds up to 30 meters (99 feet); enough to populate a local area, but not enough distance to explain post glacial seeding. Deer, however, can pass undigested trillium seeds, and do travel long enough distances to account for post glacial seeding of prairie woodlands. For this reason, deer are given credit for the wide prescence of trillium on the North American post glacial woodlands.

Trillium is also a popular symbol used by businesses (just google it). 

Locally, a trillium is used by Riverwoods, Illinois on its village sign. This plant is also the state flower of Ohio and a symbol used by Ontario, Canada.

Enjoy the view, but don't pick the blooms!




So, the next time you are in a prairie woodland or driving by a shaded country fence in early spring, look for trillium! The flowers are fun to look for and easy to find. 

If you happen to see a deer grazing nearby or spy an ant on a trillium bract or flower, just remember they are seeking the same woodland treasure as you are.

Until next time. And remember to stay on the trail (and don't pick the trillium).
