In a first-time summer internship research project, two college students set out to understand how plants were responding to the Garden’s shoreline restoration projects. They took a deep look into how variations in water levels may be affecting the health of the young plants. The results of their work will help others select the best plants for their own shorelines.
A silent troop of more than one-half million native plants stand watch alongside 4½ miles of restored Chicago Botanic Garden lakeshore. The tightly knit group of 242 taxa inhibit erosion along the shoreline, provide habitat for aquatic plants and animals, and create a tranquil aesthetic for 60 acres of lakes.
Now ranging from 2 to 15 years old, the plants grow up from tiered shelves on the sloping shores. Species lowest on the slope are always standing in water. At the top of the slope, the opposite is true, with only floods or intense downpours bringing the lake level up to their elevation.
Jannice Newson and Ben Girgenti moved through clusters of tightly knit foliage along the Garden shoreline from June through August, taking turns as map reader or measurement taker. On a tranquil summer day, one would step gingerly into the water, settling on a planting shelf, before lowering a 2-foot ruler into the water to take a depth measurement. The other, feet on dry land, would hold fast to an architectural map of the shoreline while calling out directions or making notes.
Newson, a Research Experiences for Undergraduates (REU) intern and sophomore at the University of Missouri, and Girgenti, a Garden intern and senior at Brown University, worked under the guidance of Bob Kirschner, the Garden’s director of restoration ecology and Woman’s Board curator of aquatics.
When the summer began, Girgenti and Newson had hoped to locate and measure every single plant. But after the immense scope of the project became clear in their first weeks, they decided to focus on species that are most commonly used in shoreline rehabilitation, as that information would be most useful for others.
View the Garden’s current list of recommended plants for shoreline restoration.
“We’re interested in which plants do really badly and which do really well when they are experiencing different levels of flooding, with the overall idea of informing people who are designing detention basins,” explained Girgenti, who went on to say that data analysis of the Garden’s sophisticated shoreline development would be especially useful for others.
“The final utility of this research will be to inform other natural resource managers,” confirmed Kirschner, who added that successful Garden shoreline plants must be able to withstand water levels that can rise and fall by as many as 5 feet several times in one year.
Steering the Ship
Along the shoreline, the interns followed vertical iron posts that were installed as field markers during construction, in order to find specific plants shown on the maps. “The posts are pretty key to being able to map out the beds,” said Girgenti.
Once they found a target plant, they then counted clumps of it, and put it into one of six categories based on the amount of current coverage, ranging from nonexistent to area coverage of more than 95 percent.
They also measured the average depth of water for beds with plants below the water line, noting their elevation. For plants above the water line, the elevation was derived from the architectural drawings.
Data about the elevation and coverage level of each measured plant, together with daily lake water level readings dating back to the late 1990s, was then entered into a spreadsheet and prepared for analysis to identify correlations between planting bed elevation and plant survival.
Beneath the Surface
For her REU research project, Newson was careful to collect data for one species in particular, blue flag iris. “As a preliminary test of the project hypothesis, data relating to 101 planting beds of Iris virginica var. shrevei were analyzed to see if there was a significant correlation between the assessed plant condition and each planting bed’s elevation relative to normal water,” she explained in her final REU poster presentation in late August.
An environmental science major, she initially experienced science at the Garden as a participant in the Science First Program, and then as a Science First assistant, before becoming an REU intern.
Girgenti began his Garden work in the soil lab, where his mentor inspired him to focus on local, native flora. “I was kind of pushed up a little bit by the Garden,” he said. The following year he did more field work in the Aquatics department. “I wanted to come back because I really enjoyed being here the last two years,” he said. “Every year I’ve come back to the Garden, I’ve been very excited about what I’m going to do.”
Aside from the scientific discovery, the two also refined their professional interests. “I do enjoy being out in the field as opposed to maybe working in a lab; it’s a lot more interesting to me. And also just working in the water with native plants is very interesting,” said Newson.
“I was really interested in getting into more of the shoreline science and also learning which native species were planted there,” said Girgenti. “I really love working here. I’ve never really been involved this much in science, so this has been a really great experience—just all of the problem solving that we’ve had to do over the course of the summer.”
Newson also enjoyed the communication aspect of her work, as Garden visitors stopped to ask what work she and Girgenti were doing along the shoreline. She was especially excited to share with them and her fellow REU interns that “the purpose of why we are doing this is that it provides a beautiful site for visitors to see, it helps with erosion, and also improves aquatic habitat.”
Although the interns have left the Garden for now, the data they collected will have a lasting impact here and potentially elsewhere. Kirschner is currently working with his colleagues on the data analysis to complete a comprehensive set of recommendations for future use.

The flowers are gone, the trees are bare, now what to photograph? Birds, of course! Winter is a great time to get some fabulous shots of winter birds. One huge bonus is that there are no leaves on the trees and the birds are much easier to see!
There are the “regular” local birds, like robins (yes, some robins do stay around all winter), goldfinches, cardinals, chickadees, mallards, Canada geese, red-tailed hawks, and cedar waxwings, to name a few. Plus, winter has the bonus of birds that actually migrate to our area just for the winter. Some migrants you will see every year are juncos, tree sparrows, and a variety of ducks. Other birds are occasional, or eruptive, and only show up once every few years, like pine siskins, red-breasted nuthatches, and redpolls. Then there are the, “wow! I’m really lucky to find this species!” birds, like crossbills, snowy owls, bald eagles, and bohemian waxwings. That is the fun part—you never know what you will find on any given day. That is why I go out every chance I get!
You can check the list of birds that you can expect to see at the Garden here.
When you get to the Garden, some places to look are all the trees with berries! Yes, the birds love them. Another good place to look is the Dixon Prairie, where all those seeds attract a lot of birds. Be sure to check out the bird feeders at the Buehler Enabling Garden too. You can also find a variety of birds—especially woodpeckers—in the McDonald Woods. If there is open water, check there for ducks and geese. You might be surprised at just how many birds you can find in winter.

When you lift a rock in your garden and glimpse earthworms and tiny insects hustling for cover, you’ve just encountered the celebrities of soil. We all know them on sight. The leggy, the skinny, the pale…the surprisingly fast.
Behind this fleeting moment are what may be considered the producers, editors, and set designers of the mysterious and complex world of soil—fungi. They often go unrecognized, simply because most of us can’t see them.
Fortunately, new technologies are helping experts, like Chicago Botanic Garden scientist Louise Egerton-Warburton, Ph.D., get a better look at fungi than ever before, and discover vital information.
“One of the problems we have with soil science is that you can’t see into it so you really depend on a lot of techniques and methods to work out what’s happening,” explained Dr. Egerton-Warburton, associate conservation scientist in soil and microbial ecology.
In the last year, she has used high-throughput sequencing (also termed Next Generation Sequencing) to identify more than 120 species of mycorrhizal fungi in a single plant community. In contrast, previous reports suggested there were, at most, about 55 mycorrhizal species in a plant community. These tiny heroes are microscopic organisms that attach themselves to plant roots, for example, to carry out critical functions that support all life on earth. They are essential for the well-being of more than 85 percent of all plants, including those in your garden.
Mycorrhizal fungi are fungi that have a symbiotic relationship with roots of a vascular plant; from the Greek for “fungus” and “root.”
If climate change results in more intense rainfall and drought—as is predicted by climate change scientists—mycorrhizal fungi will also play an important role in processing varied levels of water in the soil.
Egerton-Warburton has just returned from November field work in the Yucatán peninsula of Mexico, where she has been testing the responses of mycorrhizal fungi to changes in rainfall and soil moisture, especially to drought. Will fungi be able to keep pace? Will they be able to survive? What does that mean for other plant life? “Fungi are really good indicators of any environmental problems. So they are more likely to show the effects of any environmental stress before the plants will,” she said.
Each type of fungi also has a specific role, according to Egerton-Warburton, with some specialized to take up nutrients from the soil, while others cooperate to complete a function, such as fully decomposing a leaf. A lot of fungi are needed to keep the system working. “You get 110 yards of fungal material in every teaspoon of soil,” she explained.
Aside from breaking down deceased plant material, fungi play a key role in many plant-soil interactions and the redistribution of resources in an ecosystem. They filter water that runs into the ground, cleaning it before it hits the bottom aquifers and drains out into rivers. Also, in the top few inches of soil, many fungi are respiring, along with their earthworm and other living counterparts, helping to filter gases and air that move through the system. Of growing interest, is also the fact that fungi could have a major role in soil carbon sequestration.
Soil carbon sequestration is the process of transferring carbon dioxide from the atmosphere into the soil in a form that is not immediately reemitted.
For the past four years, Egerton-Warburton and colleagues at Northwestern University have been working to better understand the flow of carbon through fungal communities that results in long-term soil carbon sequestration. Soil’s capacity to store carbon is a reason for hope and a potential way to mitigate climate change. According to Egerton-Warburton, soil is known to hold three times more carbon than plants and trees above ground. “Maybe there are other ways we can manage the systems and enhance that capacity in the soil,” she said.
The study has required a lot of ‘getting to know you’, as the researchers first sought to identify each type of fungi involved in the process of carbon sequestration. As plant parts above ground are faced with absorbing and converting larger and larger amounts of carbon dioxide from our atmosphere into sugars, and sending it down into their roots, the more beneficial it will be to have a healthy suite of fungi waiting to receive it, use it, and move it along for future long-term storage.
Part of this equation has been to understand which fungi benefit from the increasing supply of sugar. Previous work by Egerton-Warburton has shown that mycorrhizal fungi respond to increases in atmospheric carbon dioxide by producing large quantities of hyphae, a fine root-like structure, in the soil. This is because increases in atmospheric carbon dioxide allow a plant to produce more sugars during photosynthesis, and these sugars are shunted below ground for use by roots and their mycorrhizal fungi. At the other end of the equation are saprophytic and decomposer fungi, waiting to break down the new hyphae.
Recent work in the Dixon Prairie has used the high throughput sequencing and chemical fingerprinting to identify the fungi involved in this decomposition phase. Once that is resolved, they will be able to better understand how the fungi interact and balance the cycle carbon through specific pathways of activity.
The more the merrier, when it comes to fungi, and when it comes to people who are willing to help them endure, said Egerton-Warburton. The scientist often works with students who are interested in careers in the field, but encourages additional people to consider this critical line of work. “There’s a real need for soil ecologists in the country,” she said.
The good news is that the future story of fungi is one we can all help to script. Gardeners, she advised, can pay attention to the type of mulch they use in their garden, and plant lots of native species that will naturally enrich the function of that wonderful world that holds us up.

For one December session of our Plant Explorers after school program at Chicago International Charter School—Irving Park, the students made living ornaments for the holidays.
This tiny terrarium project can have a calming influence on a potentially hectic holiday, because green and growing plants make us feel more relaxed. It requires you to find some live moss, but it makes an extra special decoration for kids—and adults—who love plants.
To make your own “moss-some” terrarium ornament you will need:
- 3-inch or larger plastic sphere ornament that splits into two halves (available at craft stores)
- Live moss that you find growing in a shady place in your yard (or you can buy it from a garden store that sells terrarium supplies)
- Activated charcoal (sold in garden and aquarium stores)
- About 12 inches of decorative ribbon
- Any miniature item you want to add for whimsy (optional)
Separate the halves of the DIY ornament. If your ornament is like mine, it has little “loops” for attaching a hook at the top. Start by tying a 12-inch piece of ribbon to each half of the ornament through the loops.
In one half of the ornament, add about a teaspoon of activated charcoal. Fill the rest of that ornament half with very wet soil to about a half inch below the top.
Place the moss on top and gently press it into the soil. If you like, add a miniature object to add a little whimsy. Craft stores have lots of miniature objects that would look good in this ornament. We chose these woodcut reindeer to look like the animals were walking through a forest. And there were enough in the pack for all 15 students to get one. Use whatever you like!
If you have a spray bottle with water handy, it helps to give the moss leaves a gentle misting before closing the ornament.
Place the other half of the ornament on top, but instead of lining up the two loops, put them at opposite ends so that you can hang the ornament ball sideways and not disturb the arrangement. You can tape the two halves together with clear tape if you are concerned about them coming apart. I suggest only taping the sides near the loops rather than wrapping it all the way around so the tape is less obvious and you can open the ornament later if you want to.
The moss just needs light from your home to survive through the holidays. Moisture will evaporate from the soil and will collect on the insides of the ornament. It will roll back down to keep the moss watered indefinitely.
Now you’re wondering if (and how) the moss will survive. I have your answers: read on.
Some Facts About Moss
Mosses are simple plants that scientists classify as bryophytes.
What you see as a clump of velvety green carpet is actually hundreds of tiny individual moss plants clumped together. Botanists refer to these as gametophytes.
Mosses do not have true roots. They have rhizomes that anchor the plant to the soil and send up buds for new individual moss plants, but the rhizomes do not transport water like true roots. Mosses absorb water, nutrients, and carbon dioxide through their leaves.
The rhizomes are fine and grow at the surface of wherever they are planted, so they do not require deep soil. As a result, moss can grow in any porous surface, like tree bark or a stone (but maybe not on a rolling stone!). So moss can thrive in the small amount of soil in your ornament. The moisture sealed inside the globe will keep the air humid and supply the leaves with water.
Mosses also do not flower or make seeds. They produce tiny spores that are difficult to see without magnification. The spores are carried by wind until they fall, and there they wait for the right conditions to grow into new moss plants.
If your moss dries up or becomes dormant, do not despair! You can bring it back to life by soaking the dry clump in water and keeping it moist. This will reinvigorate the dormant moss and activate spores that are lying hidden in the dry moss, enabling them to grow into new moss.

Handmade greeting cards make people feel loved. Here is a fun and festive way to show friends and relatives that you care about them. It’s a great project for kids who need something to do during Thanksgiving break. (It’s also a way to use up some of those 20-year-old spices that are languishing in your kitchen cabinet!)
- White glue in a squeeze bottle
- Construction paper
- Dried herbs and spices, whole or ground
- Salt and water in a small dish, with a paint brush
- Markers, crayons, or colored pencils
Work over a large paper towel or mat, because this project is messy!
Fold a piece of stiff paper (construction paper or card stock) in half. Draw a design with glue on the front of the card. Try to use glue sparingly, because the paper will warp if the glue is too thick or wet. Sprinkle the herbs or spices of your choice on the wet glue.
You can apply the spices by gently tapping them out of the jar onto the page, or take small pinches and apply them where you want them to go. If you want more control, fold a small piece of paper in half, put some spices in the crease, and gently tap the paper to slide the spices down the crease to apply them to your picture.
It helps if you make the glue design for one spice at a time, and let each spice dry before putting a new one on. When each spice has dried, shake the card to remove excess, and apply glue for the next spice. This reduces blending.
Dried herbs are all slightly different shades of green. Tarragon leaves are a lighter green, and a little brighter than oregano. For yellow, try ground turmeric or curry. Paprika, cinnamon, chili powder, and crushed red pepper flakes deliver warm reds. Pink and green peppercorns make nice accents. Cream of tartar and alum powder dry white, but require special handling or they will flake off. Everything sticks better if you gently press the herbs into the glue.
You can also glue whole spices such as bay leaves, cloves, fennel seed, or pieces of cinnamon bark to the card. Keep in mind that whole spices will make the card bulkier and may make it difficult to fit the card into the envelope.
Want to add some sparkle? Glue salt crystals in some areas or paint salt water on the paper with a fine paintbrush or cotton swab. Like glue, you’ll want to use a light touch so the paper does not become too wet and wrinkled.
My daughters are teenagers, so they made an effort to make a picture of something recognizable. If you have younger children, they will probably make a picture that resembles abstract art. It doesn’t matter, because it will still smell wonderful! What’s important is that they make it themselves and have fun doing it.
After the glue is completely dry, gently shake the card over a bowl one final time to remove the loose spices. When you are finished working on this project, you can place all of the leftover spices from your work area into a bowl and place them in a room to make the air fragrant.
One final step: don’t forget to write your message on the inside! You might say something clever like, “Seasoning’s Greetings,” “Merry Christmas Thyme,” “Have a Scent-sational Hanukkah,” or “Wishing You a Spicy New Year.” Don’t forget to sign your name!
A card like this does not fit into an envelope easily and is best hand-delivered. If you must mail it, cover the front with a piece of paper to protect it. Carefully pack the card with a stiff piece of cardboard in a padded envelope to reduce bending and crushing while it’s in transit. If you are delivering a small bundle to the post office, ask them to hand-cancel your cards (they’ll appreciate the tip).
I hope your special creations brighten someone’s day and fill them with memories of good times with family and friends!
