Thanks…for Giving

In honor of our volunteers

Karen Z. —  November 26, 2014 — 1 Comment

There are in the neighborhood of 1,400 volunteers working, helping, contributing, and giving their time and energies to the Chicago Botanic Garden. This fact about the Garden amazes me every time I hear it.

Isn’t that astounding?

I began at the Garden as a volunteer, too, so this Thanksgiving, I wanted to talk to a few others to find out when, where, how, and why they volunteer.

Suffice to say that I met some awesome people. It’s a pleasure to tell their stories—and to honor them in this season of giving thanks.

Volunteers Can Connect

Five years ago, Jack Kreitinger bought his first ticket to Wonderland Express—and promptly fell in love with the show. An architect by trade, “I wanted to build those little houses out of bark,” he laughs. Instead, he attended that year’s Volunteer Fair and signed up to become a guide for the walking tour program. (Mark your calendar: our next Volunteer Fair is Sunday and Monday, March 1 and 2, from 1 to  3 p.m. in the Regenstein Center.)

Jack’s Favorite Getaway

Here, Jack gives a walking tour; he knows all the best spots in the Garden. He loves the viewing area at the top of the hill in the Sensory Garden, “where you can look through the tops of the trees down at the water. Someday I hope to buy a tree and donate it to be planted as part of that view.”

For Jack, volunteering is about making connections with other people. “Gardeners are the coolest people on earth,” he says. “I’ve met such interesting people from all over the world and, as a tour guide, I can convey how much I love the Garden and why they should love it, too.” Jack’s natural communication and leadership skills have transformed the Walking Tour Guides team as well: he’s a volunteer team leader.

A committed time slot works well for Jack: Thursday mornings find him leading a 45-minute tour from the Crescent Garden through the Heritage Garden, Bonsai Collection, Circle Garden, Buehler Enabling Garden, English Walled Garden, and Krasberg Rose Garden; a second tour lasts a little longer since it’s open-ended.

“It grounds me in nature,” Jack explains, “since I get to see the changes in the gardens week by week, spring through fall.” Between his regular schedule, VIP tours, and special events (he takes special request tours!), Jack estimates that he’s hosted 1,500 people on tour in his five years as a volunteer.

“I get more out of it than I give,” he says. We respectfully and thankfully disagree.

Volunteers Can Specialize

Eight years ago, Ann Stevens took her first course in beekeeping. Seven years ago, the Regenstein Fruit & Vegetable Garden purchased eight new beehives and needed a beekeeper. It was a perfect match.

Ann’s Favorite View

Ann loves seeing the beehives nestled into the apple trees from across the water at the Esplanade. “It reminds me of the big picture: what the bees do for us, how they teach us about community, about working hard to benefit each other, all in an organized and logical way.”

Six years of volunteer beekeeping later, Ann does the math:

  • 50,000 bees at the end of each summer
  • x eight beehives
  • x six years
  • = 2,400,000 bees

That’s a lot of beekeeping. And Ann’s work is a great example of the specialized roles of some volunteers at the Garden.

“I love the freedom of it,” Ann says. “It’s a job I can go to when the weather’s right for the bees. I love the seasonality of it: starting new hives, getting them settled, working through the seasons.”

Ann speaks eloquently about working with bees. “I learn new things from them every year. Even if hives are side by side, the results in each are different. You have to adjust, nurture, and give them your best, but you can’t control it all. There are things that are bigger than us, and I get to experience that through the bees.”

Like every volunteer that I had the pleasure of interviewing, Ann also spoke glowingly about the visitors she interacts with at the Fruit & Vegetable Garden. “It’s so beautiful to see so many different people: different ages, different languages being spoken, young couples, families teaching kids to be respectful of the garden. There’s an international feeling at the Garden, and I get to be part of that. I’m so grateful.”

We’re grateful, too, Ann.

Volunteers Can Contribute

First things first: Eileen Sirkin already had a Ph.D. in microbiology and a long-time family membership at the Garden before she became a volunteer.

Eileen’s Favorite Place

“The Butterflies & Blooms house in peak season is the happiest place at the Garden,” Eileen says with a smile. “The butterflies are all flying, and people come dressed in butterfly T-shirts and butterfly jewelry…some stay for hours, and some come back week after week. They all sigh with happiness.”

Ten years ago, she was ready to volunteer and to return to the field of science. Initially, she volunteered as a Plants of Concern citizen scientist (check it out here). When Dr. Jeremie Fant arrived at the Garden as a conservation scientist, she became a volunteer technician in the Molecular Ecology Lab—and has been there ever since.

“It’s like CSI for plants,” Eileen explains when asked about her lab work. Her assignments are wildly interesting (like most science!): her early work with Dr. Fant involved the selection of seagrass species to repopulate a section of Chicago’s Rainbow Beach; her current project involves the Jerusalem Botanic Garden and examines the DNA of Iris vartanii, a rare native that grows only in Israel.

Coworkers and volunteers are important to Eileen. “These are down-to-earth types of people, who love the natural world,” Eileen says. “There’s a lot of fellowship here.”

Also important is the sense of giving back and contributing to a larger cause. “The Garden saw something in me and gave me the opportunity to reactivate what was dormant—I’m grateful for the chance to return to science,” Eileen says at the end of our conversation. “I can’t leave this place. I love it.”

We’re so grateful for your contribution, Eileen.

Volunteers Can Influence

Carmen’s Favorite Spot

Carmen’s favorite? No contest: the “pepper pots” or viewing areas in the English Walled Garden, taking in the view across the water.

After 40 years as a teacher in Chicago Public Schools—teaching Spanish to kids little and big—Carmen Reyes had earned her retirement.

But after just six months, she missed the kids. And she missed teaching. So she turned to the Garden—a place that she already knew well from many summer visits—and she signed up as a greeter. When Judy Cashen, the ever-alert director, volunteer administration and engagement, asked her to help out in the education area, she jumped at the chance.

As an assistant for the school field trip programs, Carmen sets up for the classes that arrive, assists the team leaders, and does some presentations herself (her engaging approach to the subject of companion plants is always popular).

Carmen especially likes working with kids grades K through 8. “They’re wide-eyed, and they want more information,” she says. “Any bit of information that you offer is new to them.” Her bilingual skills are constantly in demand, and she often finds herself welcoming kids on field trips from her former employer, the Chicago Public Schools.

The Garden itself is a powerful draw. “You can’t beat the setting,” Carmen remarks. “And regardless of the time of year, there’s always something beautiful to see, something good for the soul. I’m thankful for the people who make it so beautiful and welcoming. It makes me feel like part of the family at the Garden.”

Thank you for investing in the next generation, Carmen.

Volunteers Have Fun

Carolyn’s Favorite Walk

Volunteers clean moss and lichen from birch trunks.

Carolyn and Ed Hazan take volunteering seriously…and have a lot of fun with it, too. Yes, they even scrubbed birch trees this year. Carolyn loves the woodland walk on the outside edge of the Sensory Garden. “But going for a walk isn’t always easy—every ten minutes, there’s someone to stop and talk to!”

Carolyn and Ed Hazan are the volunteer’s volunteer: they give of their time separately and together. Between the two of them, they’ve worked in nearly every garden, and the list of events that they’ve volunteered for reads like the year’s schedule at the Garden: Wonderland Express, the Orchid Show, World Environment Day, Kite Festival, Chef Series, and the Antiques & Garden Fair…and more

In 2001, when Ed decided that he wanted to learn how to grow vegetables, long-time volunteer Sam Darin suggested that he give volunteering a try. Both Ed and Carolyn began by volunteering two times per month—today they’re up to three or four days per week.

“It’s the people,” Carolyn says without hesitation when asked what drives them to volunteer. “We love it because we know everybody, and there’s always somebody new to talk to—you can never have too many friends!”

The photo of the couple says it all: they’re vibrant, intrepid, can-do people who have found their tribe at the Garden. And, yes, they’re washing the birch trees (every five years or so, the trees get a brightening scrub).

Thank you both for giving so much.

Emerald Ash Borer: Sad But True, Part 3

The invasive insect appears to have spread to a different host.

Tom Tiddens —  October 23, 2014 — 8 Comments

Last week, a college biology professor in Ohio announced he had found evidence that the emerald ash borer (EAB), an invasive insect decimating the continent’s ash trees, is also attacking white fringetrees (Chionanthus virginicus).

White fringetree (Chionanthus virginicus) in bloom

In August he found the telltale D-shaped exit holes on a fringetree near his home. When he investigated further by peeling back the bark, he found feeding galleries and live borers. He had the borers positively identified morphologically as well as with DNA tests conducted by the USDA’s Animal and Plant Health Inspection Service (APHIS). He also found evidence of EAB activity on fringetrees in three other locations in Ohio.

The recent discovery marks the first time EAB has been found completing its life cycle on anything other than ash in the United States.

The finding adds an alarming new element to the EAB story:

  • Researchers have been wondering whether the host range for EAB could be wider than just ash. That theory had seemed unlikely up to now but is proven with the fringetree discovery. There has already been a lot of research investigating other possible hosts, and with the new discovery, there will likely to be more.
  • Is the insect adapting? This is a scary thought!
  • Will EAB kill fringetrees as it does ash, or just cause damage? So far the invasive insect appears to only be damaging—not killing—fringetrees.
  • Has EAB moved to fringetrees because EAB populations are locally so high? If the buffet is crowded at the “prime rib station,” it seems logical that “meatloaf station” may get some visits.
  • What will happen when ash tree populations dwindle? Will the EAB population die back, or just move to a secondary host (the meatloaf, as the prime rib is gone) and/or develop a completely new palate?
PHOTO: A D-shaped exit hole left by EAB.

This D-shaped exit hole was left by a mature emerald ash borer as it exited this host tree.

The Ohio professor’s find was not all by luck; he had reason to focus on the white fringetree. Laboratory studies have shown that the adult EAB will feed on the foliage of other tree species in the same family as ash—the olive family, or Oleaceae. Members include ash (Fraxinus), fringe tree (Chionanthus), lilac (Syringa), forsythia, privet (Ligustrum) and swamp privet (Forestiera). Literature from Asia, the homeland of the EAB, indicates other secondary EAB hosts.

The Chicago Botanic Garden has 42 fringetrees; all have been inspected and show no signs of EAB activity. Even a fringetree that is 25 feet from an ash tree that was heavily infested with EAB shows no signs. If you have a fringetree, you should inspect it for signs of EAB. These include dieback starting at the upper limbs of the tree, new growth on the lower trunk, and small, D-shaped holes where the larvae have exited through the bark. Emerald ash borer larvae can kill a mature ash tree in two to three years by destroying the tree’s vascular system.

Find more information on identifying and dealing with EAB on our website, and in our previous posts, Signs of Emerald Ash Borer, and Emerald Ash Borer: Sad But True, Part 2.

As the world has become less fragmented by ease of transportation, more exotic, high-consequence plant pests and pathogens like EAB have entered—and will continue to enter—the country. Other exotic plant pests and pathogens we are watching for at the Garden include the following: viburnum leaf beetle, Asian gypsy moth, brown marmorated stink bug, Asian longhorned beetle, thousand cankers disease, plum pox virus, chrysanthemum white rust, sudden oak death, and so on; most are already in the country. Vigilance and education are the key to managing and slowing the spread of these foreign invaders.

The Garden is a member of the Sentinel Plant Network, a group that unites botanic gardens in monitoring and providing education on exotic plant pests and pathogens, and works in partnership with the National Plant Diagnostic Network (NPDN).

If you are a plant and bug person like me, please consider becoming a NPDN First Detector and help be on the lookout for these exotic plant pests and pathogens. The NPDN offers an online training course to become a First Detector at firstdetector.org. It’s free, and upon completion, you even get a printable certificate!

Traveling Down the Glacier

The new North Branch Trail addition opens!

Karen Z. —  September 8, 2014 — 7 Comments

There’s more to the new North Branch Trail addition than meets the eye.

It’s a great story to tell the kids or to share with a biking buddy as you try out the North Branch Trail addition

On the surface (literally), it’s a lovely new bike/pedestrian trail that slopes down from Green Bay Road, skirting the north edge of Turnbull Woods and linking up to the outer road of the Chicago Botanic Garden. But dig a little deeper (literally and figuratively), and you’ll find the reason for that slope: the “hill” is actually the remnants of a glacier. Its proper name is the Highland Park Moraine. It’s one of a series of five, collectively called the Lake Border Moraine System, found on the inland border of Lake Michigan.

Flashback to geology class: a moraine is a giant accumulation—a ridge—of clay/sand/gravel pushed forward by the leading edge of a glacier, then left behind as it shifts its motion and melts/recedes. Moraines vary in sizes and heights.

Glacial ice that once covered northern Illinois began to recede about 14,000 years ago, leaving the five moraines, like scallops in the landscape, with the oldest to the west, the youngest to the east.

Oldest and furthest west is the Park Ridge Moraine; to the east of it is the Deerfield Moraine. The lowland between them is the West Fork of the North Branch Chicago River. Third is the Blodgett Moraine; its creation dates back to 13,000-plus years ago. The valley between it and the Deerfield Moraine is the Middle Fork of the North Branch Chicago River. (The West Fork, Middle Fork, and Skokie Rivers come together to form the North Branch Chicago River.) Next comes the Highland Park Moraine, formed about 13,000 years ago; Green Bay Road was built along its crest. The Chicago Botanic Garden lies in the Skokie River Valley between the Highland Park and the Blodgett Moraines. Finally, a bit north and east lies the Zion City Moraine, the youngest of the five.

As if all that isn’t cool enough, the Highland Park Moraine is also a mini-section of the Eastern Subcontinental Divide: water from the Highland Park Moraine drains toward Lake Michigan (Great Lakes watershed) on the east side, and into the Skokie River Valley (Mississippi River watershed) on the west side.

ILLUSTRATION: A chart showing the geological specifications of the Highland Park Moraine.

Most people are familiar with the Continental Divide near the middle of the country; a secondary divide travels along our edge of Lake Michigan.

Planning & Planting

Sedges do well in spring rain/flood conditions, helping dissipate water through respiration.

Planning for the new bike/pedestrian path included much deliberation about the plants that were already growing at the site.

As construction neared, ecologist Jim Steffen reached out to Glencoe Friends of the Greenbay Trail and Betsy Leibson, who heads up the all-volunteer group, which is dedicated to restoring the sections of the Green Bay Trail bike path that run through their town (and ours).

Steffen offered to donate hundreds of sedges (Carex pensylvanica and Carex hirtifolia) that were in the path of construction—and then helped Leibson and volunteers dig them up for transplanting along their trail. The sedges are reportedly thriving. GFGT showed their appreciation in such an appropriate way: see their July 14 post about it here.

 


PHOTO: Bike.5 Reasons to Love the North Branch Trail Extension

  1. It’s safe (for all the bike riders who’ve wobbled in a vehicle’s wake on busy Lake Cook Road!).
  2. It’s ADA-accessible: 10 feet wide, smoothly paved, and appropriately inclined.
  3. It’s convenient for pedestrians heading to and from the Braeside Metra train station.
  4. It’s family-friendly for strollers and toddlers, and shepherding groups of kids toward the Garden.
  5. It’s the long dreamed-of and anticipated mile-long missing link between Cook County’s North Branch Trail and Lake County’s Green Bay Trail.

Become a Bicycling Member!

How smart is this? A special membership for those who ride their bikes to the Garden instead of driving. With plenty of perks included (discounts, member magazine, tax deductibility), but sans parking privileges, it’s a sensible and cost-efficient (just $50 annually) way to show your support for the Garden.

Lunchtime? How about a pickled pepper sandwich?

Courtesy of volunteer Larry Aronson

Karen Z. —  August 14, 2014 — Leave a comment

Out at the Regenstein Fruit & Vegetable Garden, there’s a whole group of volunteers with really interesting career histories and double-digit years of volunteer service. Larry Aronson is one of them.

You’re likely to find Larry on Thursdays at his favorite volunteer station: the Pepper Discovery Cart. There, he presides over 120 different pepper samples and flavorings. “When I started volunteering 11 years ago, there were four pepper samples and a book on the cart,” Larry says.

PHOTO: Pepper spices from the Pepper Cart.

Think there’s only one kind of paprika? Think again.

So he made it his mission to add to the cart. Dried peppers, ground peppers, pepper flakes and pepper sauces. Peppers from Brazil and Peru, France and Spain, China and Japan, Africa and South America. Well-known peppers like paprika (the seasoning made from dried and ground pimento peppers) and obscure peppers like Capsicum chacoense (an ancient species).

Ask Larry a question about peppers and he’ll not only have the answer, but he’ll also add a conversation-starting fact or story to go with it. What’s his favorite pepper to eat? It changes over time. The Brazilian malagueta pepper is a current favorite that is “better than Tabasco,” Larry says.

What’s the hottest pepper he’s got? Used to be “Ghost” (Buht jolokia), until he got a sample of Trinidad moruga “Scorpion.” Its heat level is said to be the same as pepper spray—essentially, inedible.

Which peppers does he use in recipes? Cayennes. Jalapeños. Habañeros. Why? “Because they have the most universal and interesting flavors,” Larry says. He should know—he eats peppers every single day.

Speaking of recipes, Larry recommends a favorite resource: Chile Pepper magazine. He owns every issue, and says it has the best recipes in the world.

Volunteer Larry Aronson at the Pepper Discovery Cart—come and chat with him on Thursdays!

A professional chef and baker on his non-volunteer days (he’s owned 27 restaurants in his six-plus decades of cooking, including Chicago’s My π Pizza), Larry likes to re-create recipes for great food that is new to him. (He’s in the process of writing a cookbook now.)

While talking recipes, Larry mentioned that he had a new favorite sandwich, using his favorite recipe for pickled red peppers. Naturally, we asked if he’d share.

Larry Aronson’s Pickled Red Peppers

  • 1 ounce sugar
  • 1 ounce salt
  • 1 cup white vinegar
  • 3 cups water
  • 1 bay leaf
  • 1 tablespoon pickling spice, tied in cheesecloth
  • 1 medium carrot, peeled, cut into ½-inch slices
  • 1 medium onion, peeled, cut into ½-inch slices
  • Fresh red pimento peppers, cut into ½-inch slices (amount will depend on pepper and jar size; may substitute other sweet red peppers, such as red bells)
  • Fresh red jalapeño peppers, cut into ½-inch slices (amount will depend on pepper and jar size; may substitute serranos)

In a saucepan, bring the first six ingredients above to a boil. Add the carrots to the boiling liquid. When carrots start to soften (test with a fork), remove from boiling liquid.

PHOTO: Pickled red pepper and turkey sandwich.

Larry’s favorite sandwich: turkey/mayo/pickled red peppers on homemade white bread

Pack carrots, chopped onions, and a mix of 50/50 chopped sweet and hot peppers into sterilized jars. (Follow manufacturer’s instructions for sterilizing jars and lids.) Pour hot pickling liquid over vegetables, filling to ¼-inch from the top of the jar. Seal with sterilized lid and screw top. Let sealed jars cool.

Larry stores his pickled peppers in the refrigerator for several months.

To make a great sandwich: On homemade white bread, spread mayo, then layer with sliced turkey and pickled red peppers.

Alternate serving: Cube fresh turkey and combine with mayo and pickled red peppers as turkey salad. Delicious served with chicken, too!

Our volunteers are awesome.
