At the Root of Things
April 18, 2018 - An Owl’s Perspective: ‘Hoo Should Give a Hoot? YOU
By Ollie the Owl (and Alexus Minervini, Trees Forever Intern)
Imagine your normal day: working, going to school, running errands, and coming home only to find that your home has been broken into or destroyed! This is the reality for wildlife all around the globe. Many people focus their attention on faraway places like the Amazon and they do not realize that it may be happening right now—in their own backyards! Most homeowners are not aware of all of the wildlife who also call their property home.
Not having a place to live is an all too common problem for woodland creatures, like myself. Owls, like many other animals that live in forested areas, use trees to rest in, raise our young, or as a hiding place from predators. When it comes to the importance of tree conservation and planting trees, you humans are always talking about how trees are a great resource for filtering air – taking in the carbon dioxide most of us can’t breathe and giving back the oxygen we need. While having clean air is a great benefit of trees, oxygen is not the only reason why trees are important.
As a barred owl, my species lives in forested areas for the majority of our lives. My family prefers the red oak, white oak and burr oaks near Wickiup Hill Learning Center outside of Toddville. Oaks are native to Iowa and provide homes for me and many other species. I have lived in trees my entire life, so trees mean a lot to me – the difference between life or death in some cases. Not having trees in my life would be like you not having access to a grocery store, I wouldn’t be able to hunt and would struggle to find food. Not only are trees my home, they also make up my territory – an important fact to consider since this also impacts my dating options and my potential offspring.
Just as people want to protect their families, I want to protect mine as well. In order for me to keep my family safe, I need the help of trees. As little owlets, my nestmates and I spent weeks in our nest before we were strong enough to explore our nesting tree and the surrounding area. Not having enough trees means that I won’t have a safe place to raise my own young one day.
You can help me, my family, and my whole species survive by planting trees. In fact, planting trees is good for all of us! For those of us who live in the woods, the trees help provide shelter and nesting grounds. For you humans, trees can help with energy costs, storm water retention, and increase your property value.
This Earth Week, think of trees and why we need more trees to create a better tomorrow for everyone! The next generation—of both Barred Owls and humans—should be able to enjoy an abundance of trees and see the amazing amount of wildlife that rely on trees for their survival.
Come show that you “give a hoot” by joining Trees Forever during Earth Week Blitz. You might even see me if you come to the FREE family friendly event Give a Hoot About Owls and Their Habitat! with Linn County Conservation on Thursday, April 26 from 7 - 8 p.m. at Wickiup Hill Learning Center!

February 21, 2018 - A Letter on Why Iowa Senate File 2311 is BAD for Iowa
The following letter was written to Iowa State Senator Dennis Guth by a Fenton, Iowa constituent, regarding Iowa Senate Study Bill 3093, which evolved to Iowa Senate File 2311 (click here to read the full bill). Trees are proven to be an engineering marvel—saving energy on shade in the summer and protecting us from winter winds in the winter, sequestering carbon and absorbing stormwater. With Iowa losing trees from emerald ash borer, maintaining tree canopy in towns and neighborhoods will be difficult without utility support for trees. Please join us and write your representatives.
Good morning Senator Guth,
I am a constituent of yours living on a farm just north of Fenton. I have never contacted you before to provide feedback on any position, but am motivated to do so today in regards to senate study bill 3093. This is a terrible bill for many reasons: proper oversight, fairness, gutting of energy efficiency standards, potential to impact the solar industry in Iowa; all these are good enough to stop this bill in its tracks.
However, my main reason for contacting you this morning is to educate you on the benefits of trees for energy efficiency. I've heard some reports that some things might have been said snickering at the effectiveness of planting trees for energy efficiency in our communities. I hope that providing you this information can put that non-sense to bed and you can have the confidence to point out to any other individual that questions trees for energy efficiency the misconception.
Below are some figures I think you will find interesting. The first column is the annual energy savings for some selected communities in District 4 due to trees (includes both electricity and natural gas), the second column are the total of ALL benefits, from energy efficiency, to storm water cost reductions, to carbon capture, air pollution benefits, and even property value increases.
||Annual Energy Savings
||Cumulative Value of Benefits
All of these figures can be found by reading through the Urban Forestry Management plans each of these communities has completed. They can all be found at this link (with the Iowa Department of Natural Resources Urban Forestry) http://www.iowadnr.gov/Conservation/Forestry/Urban-Forestry
These are real and significant dollars. Furthermore, the following communities have used energy efficiency funding through the utilities to plant trees for energy efficiency and other multiple benefits.
||Accessed Energy Efficiency Funding
||Applies to Black Hills Energy Power of Trees program every other year, typically $3K - $4K per project
||Projects with Alliant Energy Branching Out
||Projects with Alliant Energy Branching Out
||Pheasants Forever and Rotary applies to Black Hills Energy Power of Trees program every other year, typically $7K
||Projects with Alliant Energy Branching Out
||Projects with Alliant Energy Branching Out
To top it all off, we are looking at a concerning situation developing with emerald ash borer (EAB), an invasive species that is decimating our ash trees. Guess what is the single greatest species of tree in Iowa as a whole and especially as street trees? Ash trees. Looking at some of those community forestry reports some communities have as much as 30 - 40 percent of the trees in parks and right-of-way are ash trees. We will lose those trees and all the benefits that go with them. We need a MASSIVE effort to re-forest our communities, and the energy efficiency programs through the utilities help us get that job done. Oh, and just in case you thought we have time to spare, EAB has been confirmed in Martin County Minnesota, just north of where I live.
In conclusion, please don't support this bill, I don't even see how it could be amended given all the issues within it. Second, please give some thought to trees as more than a nuisance you have to pick up after. They provide real and lasting benefits. Those dollar figures for the communities in your district are ANNUAL dollars. Finally, I would ask for your support and assistance in whatever way you can to help get trees, shrubs, and other perennials on an equal footing for funding if a federal infrastructure bill is every passed. Initial news is that the federal government will rely on states and local governments to work with them to identify priorities for infrastructure. Trees and other perennials can provide immense benefits compared to their costs for "green infrastructure" and those needs should be included and prioritized for funding if the opportunity ever arises.
I look forward to visiting with you.
A Fenton, Iowa constituent
January 24, 2018 - Leaf It to the Kids
The new year is a time of reflection of what we left behind in 2017 and an opportunity to put a fresh perspective on the upcoming year. Trees Forever is excited to shape 2018 with a new theme: Leaf it to the Kids.
We chose this theme because we need all generations involved in conservation endeavors in order for those efforts to truly be successful. As always, our mission is to plant and care for trees and environment by empowering people, building community and promoting stewardship. In our reflections, we know that we are doing this important work because we aim to leave the next generation with a healthy planet, but we also need take the time to pass down the skills and knowledge they need to care for the planet.
Join us for a moment to reflect on why you are involved with Trees Forever. When did you start to care about the environment? What inspired you to do so? Mentors of our youth often leave an imprint in our memories and values, and this year, our resolution is to make more time to create those imprints on the next generation. After all, how we leave the planet for the next generation is at the heart of everything we do at Trees Forever!
You’ll see this value in all of our programs. If you’ve ever been to one of our tree plantings, you know that our plantings are hands-on lessons on the benefits trees provide—from cleaning our air, water and soil to helping homeowners save energy and money. Also as we work with landowners on water quality initiatives to create buffers near our waterways, we do so because we want clean water for ourselves, our families, our community and the people who come after us.
At the end of our lives, we want to leave behind a legacy in our land and our actions. Consequences from how we treat the land await the next generation whether we take positive action or stand by idly. Let’s make positive movements towards a brighter future. When we leave this planet to our kids, let’s leave it better than we inherited it, and let’s give the next generations the tools to take care of it! We’re not just going to LEAVE it to the kids to figure it out on their own; we’re going to “Leaf It to the Kids.”
November 30, 2017 - Trees: Nature’s Engineers in Cities
by Shannon Ramsay, Trees Forever Founding President & CEO
What other work of creation gives us so much beauty while delivering communities’ basic needs? After a long drawn out fall with plenty of gorgeous color, we have more time indoors to contemplate nature, including winter silhouettes of trees against lovely sunsets. Even in the winter, our trees and forests are performing by holding soil in place and providing food that still clings to branches. They provide habitat for overwintering creatures that emerge and do good things in the spring. They welcome people to get outdoors, to walk and to relieve the winter doldrums.
Yes, we are left with leaves to rake. It is a chore but short-lived. While you are raking, remember that the leaves are great for compost that replenishes soil and that your trees can improve your property values and significantly lower your home energy costs.
Winter dormancy is an important time for trees. They take that time to concentrate their energies for the burst of growth in the spring. Then through the spring, summer and fall, they capture air pollutants, cool hot city places, and provide pleasant spaces to step out and bring down stress levels.
For more than ten years, Trees Forever and the Holloway Family Environmental Trust have held an educational gathering in Cedar Rapids on the value and benefits of our natural assets. Today many other sponsors and partners have joined us to continue learning in an exciting forum with national and local experts. Tree lovers and huggers are welcome to join in roundtable discussions with general outdoor enthusiasts, planners and stormwater engineers, farmers and foresters and elected officials with city staff.
Returning by popular demand, Dr. Kathleen Wolf is an internationally known researcher with the ability to speak with any audience on why we need to invest more in managing, planting and generally restoring more nature to our cities and backyards. According to Dr. Wolf, “People have long recognized that nature in cities and towns provides beauty and respite. However, more green space also improves public health - ranging from individuals to entire communities. Our trees and other natural areas are also part of a ‘green infrastructure’ system that can be planned and integrated with buildings, roads and parking to create more sustainable urban environments.” She adds, “We’re also learning that nearby nature can be co-designed for co-benefits. Building a rain garden or bioswale for stormwater management? It can also become a micro-park that makes for better human habitat.”
We gain so much benefit from the trees and green spaces around us. They are often the unnoticed backdrop of our lives, and not given much attention by most people. Yet this is changing, as scientists and engineers learn more about how green infrastructure can improve the workings and reduce costs of traditional gray infrastructure. Well planned and managed trees and natural areas make us happy, and help reduce community challenges such as flooding and air pollution. Yes, trees are good, in all seasons of the year. Please join us at the Symposium on December 7th to learn more and join in community discussions.
August 2, 2017 - Is this the beginning of the end for Iowa’s forestry programs?
by Jackie Wedeking, Trees Forever Communications and Marketing Manager
The recent decision for the Department of Natural Resources to dissolve its Forestry Bureau raises alarms. I’m concerned it is the beginning of the end of the Iowa forestry program, and as a citizen of Iowa, this doesn’t sound like the state I know my fellow Iowans love and value.
In an effort to address a $1.2 million department budget cut, the DNR eliminated multiple positions and divided the bureau among other departments. The loss of the positions is disheartening, but the decision also will devastate the future of the forestry programs.
Think about what it really means to dissolve a bureau: to break it into pieces and take away its name.
As a citizen, how do you track funding for an agency that doesn’t exist? How does such an agency stay transparent so the public can verify the organization is truly following Iowa’s values?
How easy would it be to slowly eliminate every service the bureau once provided and not hear a word from the public because the public can’t track what’s going on?
Positions that once existed under the Forestry Bureau will be under the supervision of departments with different priorities. When those departments are called on to cut their budgets, what positions do you think will be eliminated?
I’m betting it will not be the positions that directly align with that department’s core mission and values, but instead the positions that were arbitrarily tacked on to the department.
According to the National Association for State Foresters, Iowa will be the first state without a forestry bureau. In this move to dismantle the forestry bureau, a strong signal has been sent that trees and forestry are not a priority to the Iowa DNR. That will impact how the state is perceived when it applies for federal grants. Why would the federal government want to fund programs that aren’t being managed?
There will no longer be a line item labeled Iowa Forestry, but instead the budget will be broken up among other departments. Funds can be slowly siphoned off until no money is put towards Iowa’s forests and trees.
The Forestry Bureau helps small communities replant and recover after diseases and pests (such as emerald ash borer) kill the trees. The Forestry Bureau teaches woodland owners how to restore private land and combat invasive species.
These services directly impact many small communities and landowners, but they indirectly impact us all because healthy trees help create a healthy community.
Trees clean our air, water and soil. Trees shade our homes, reduce stormwater runoff during flooding and provide habitat for wildlife and pollinators.
If you like to hunt, if you like to spend time in natural areas, if you like to eat food (tree nuts, fruit that grows on trees, foods that are pollinated by pollinators that feed off or are sheltered by trees), breathe fresh air and drink clean water, you should care about this.
I urge you to contact your legislator to tell them just how much you value Iowa’s forests, trees and woodlands before it’s too late and it really is the end of the Iowa Forestry Bureau and all the services it provides.
April 11, 2017 - A Tree is Not a Forest
As you walk through a forest, what do you see? Do you see the flora and the fauna as a whole? Do you single out your favorite tree, plant, or bird? When German forest ranger and author Peter Wohlleben walks into a forest, he sees a deeply connected network of trees that work together for the benefit of the entire forest.
Wohlleben’s breakthrough book The Hidden Life of Trees: What They Feel, How They Communicate—Discoveries From a Secret World (2016) gives a fascinating combination of professional research and personal research that helps readers to reimagine trees as a tight-knit community. To do so, he writes about multiple ways in which trees communicate with each other. For example, some trees give off chemicals when threatened by a predator. When an animal nibbles on a leaf, one tree senses the threat and gives off a chemical that reaches other trees in the area. This warns other trees to emit the same chemical in order to ward off the predator. Trees work together as a community to defend themselves against a common threat.
Another fun fact that Wohlleben provides: trees avoid in-breeding by alternating the release of seeds or changing their receptivity to fertilization. Similar to humans and animals, trees have adapted to keep their species healthy and striving by working together.
Next time you take a walk in the woods, look closely at the trees around you. Perhaps you can find other evidence of trees working together and helping one another. Trees are more complex than we typically imagine, and the more curious we become about them the more we will learn from them.
March 9, 2017 - The Birds & the Trees: Revisiting Rachel Carson’s Silent Spring
It’s almost officially spring! As the season turns, many of us nature-lovers anticipate our favorite birdsongs. Whether it be the calming tweet of the American goldfinch or the alarming chirrup of the robin, many Iowa birds are beginning to make their call to nature and we can’t help but listen.
It hasn’t always been as easy to tune into nature, though. In 1962 Rachel Carson’s eye-opening book Silent Spring brought the decline of nature to the public eye. In the chapter titled “And No Birds Sing,” Carson gives accounts of local Midwesterners who noticed a sharp decrease in the bird population following the mass spraying of elm trees in 1958. Indiscriminate and ill-timed spraying of trees, though a popular means of pest control, negatively affected the surrounding wildlife and the trees themselves.
So what happened, exactly? The chemicals stayed in the leaves and the bark of the trees and, come fall, the poisoned leaves fell to the ground and decomposed into soil. The chain-reaction continued: earthworms lived in the poisoned soil and became poisoned themselves, birds ate the earthworms, and birds died because of the potency of the chemical in their bodies. Fortunately, since Carson’s book made the impact of spraying known, different practices are used today to control pests and bird populations are not harmed as they were then.
Silent Spring is a great reminder of the importance of evolving ecological practices. It’s easy to take for granted the major importance of trees to our experience and enjoyment of spring. Trees provide an excellent habitat for birds, helping them create secure homes, raise young, and find food. Find out more about birds and what you can do to protect them at www.birdfriendlyiowa.org. And on March 20th when you hear your favorite bird celebrating the first day of the new season, be sure to thank the trees for their integral role in our enjoyment of spring.
February 9, 2017 - Good Things Happen WhenYou Think of Others First
After 50 years of living separate lives, high school sweethearts Barb Moine and Steve Gustafson reunited and got married. Their love story is one example of how community projects – such as Iowa’s Living Roadways Community Visioning – bring people together.
When Barb and Steve went to the high school prom together in the 1960s, Nashua, Iowa, was a vibrant community with four grocery stores, multiple gas stations, a clothing store and more. It was a central hub for nearby smaller communities. Like so many rural-America small towns, the social fabric changed in the following decades.
The interstate rerouted traffic around town. Rural communities became smaller as people moved to bigger cities, and many of the people who stayed in the rural towns commuted to more urban areas. Baby boomers like Barb and Steve watched these trends with their own eyes as they moved on in life. After high school, the couple went their separate ways. Steve’s career in corporate legal management took him all around the world, while Barb worked in education as a teacher and then a principal. Each raised families with a boy and a girl, and those children grew and now have their own children.
Their love story was put on hold for decades until a scary turn of events. Steve was a retiree in Florida when his dog was attacked by an alligator. He successfully fought back and then a barrage of reporters flocked to him. Some of their questions struck a deeper chord, and Steve started to reanalyze his life and “his purpose.”
“You almost kill yourself doing something like that,”Steve explains. “It was just the event that got my attention… Then there was a conversation focusing on ‘what are you going to do with your life and what contributions are you going to give to your community?’”
During a visit to his hometown of Nashua, he found that purpose. He noted to an old friend that Nashua had the “ugliest downtown in northeast Iowa,” and his friend pointed out several assets the community did have – such as a wellness center, welcome center, good quality schools and a beautiful lake surrounded by trees! His friend told him that the town needed leadership and enthusiasm.
“I can supply the enthusiasm!” Steve responded. He immediately started to identify and contact individuals who were “actually getting things done.” One of those people happened to be Barb’s son, a local architect. Barb invited Steve over to her house to see some of her son’s handiwork, and suddenly they picked up where they left off five decades ago.
Steve says things came together after a series of “miniature miracles,” and most importantly the community came together.
“When you reach out to the community, there are many, many more people than you would ever imagine who are willing to step up. They just want to be asked, and they need to be asked with some enthusiasm,” Steve said.
This trend with volunteers in small towns is not unique to Nashua. Iowa State University recently surveyed more than 27,000 Iowans from small towns to get a picture of community life. Thirty-four percent of those polled said they are not involved in community projects because they are not asked to volunteer!
Nashua applied for Iowa’s Living Roadways Community Visioning, and new leadership took the ideas and ran with them. With new faces came new ideas.
“If you’re involved in developing something, then you’re going to be more apt to support it, and I think that’s what we’re seeing.”Barb said.
People are often scared of change, but Steve and Barb believe it’s a good thing.
As the keynote speaker at the Iowa’s Living Roadways Celebration, Julianne Couch, wrote in her book, “Everyday, through acts of stubborn resilience, this region seems poised to reinvent itself, to grow new hope, to teach new lessons. Those lessons may be as simple as finding resilience through thinking locally but acting as a collective, being mindful that even long traditions are not infinite.” Trees Forever programs help small communities struggling to stay vital during an era of changing social trends. Throughout this Leaflet, you’ll see many communities that are staying resilient, and Trees Forever and partners help them through this planning process.
“I worked for the last 30 years with major corporations and I’ve seen a lot of good processes. The process that Trees Forever and partners have developed is as perfect as anything I’ve seen,” Steve advises.“Follow the process, trust the process, and it will work for the community.”
November 14, 2016 – Work Day Success
Faulkes Heritage Woods in Marion, Iowa has been the target of impactful volunteer work over the past decade. Volunteers have worked tirelessly in attempt to eradicate a major threat to Iowa’s woodlands: Japanese Barberry. This plant can be identified by its light green, teardrop-shaped leaves, vibrant red seeds, and viciously sharp thorns. Originally considered an ornamental landscaping plant, Barberry is now a threat to Iowa’s native woodlands because its seeds are easily spread. Additionally, Barberry’s root system is extensive and it outcompetes native species like spring ephemeral wildflowers.
The most recent work day on November 12, 2016 pulled volunteers from the neighborhood, the Cedar Rapids TreeKeepers class, and from Coe College. Armed with loppers, heavy gloves, and herbicide loaded into bingo daubers, fourteen friends of the forest took a short hike and got to work along the first ridgeline in Faulkes Woods. The two hours was well-spent, as a truckload full of Barberry was carried out of the area. Volunteers left the site feeling accomplished and the woods is well on its way to becoming a Barberry-free zone. Little by little, a few hours at a time, Faulkes Heritage Woods is becoming a more accessible, more naturally beautiful part of Iowa’s landscape.
September 19, 2016 - The Wonders of September
October might be the month when we expect the autumn leaves to color our world with spectacular hues, sifting the sunlight into reds, oranges, and yellows as the days grow shorter and the nights grow cooler. But for some, September is the time when the season of wonder truly begins. During this month, as we harvest the bounty of our gardens and prepare for the winter ahead, as kids head back to school and football games fill our weekends, the butterflies and birds that spend the summer with us start to prepare for their great migration to their southern winter homes.
While several of the butterflies we see each summer – such as the cloudless sulphurs
(Phoebis sennae) and Question Marks (Polygonia interrogationis)—migrate south each fall, the Monarch butterflies may make the most well-known migration. The Monarch butterflies that we see flitting from aster to goldenrod at this time of year are the fourth generation since their ancestors headed north from Mexico last spring. And, although they have never been there before, the Monarchs of September make their way 2,000 miles to the southwest to spend the winter in trees in south-central Mexico before starting the migration north again next spring.
But Monarchs and other migrating butterflies are not the only long-distance flyers that we say goodbye to at the end of summer. The graceful, acrobatic swallows we see near our farms or under bridges when we paddle rivers and streams in the summer already headed south beginning in August. Tree swallows will spend the winter along the Gulf Coast of the Southern United States and Mexico, but the other five swallow species we spend our summers with in the Midwest cross the Gulf of Mexico and head all the way to Central and South America for the winter.
Perhaps one of the most intrepid southerly avian migrant is the ruby-throated hummingbird. At this time of the year, we notice them congregating at our feeders or, if we grow flowers such as the cardinal flower (Lobelia cardinalis), we see them busily visiting flower after flower, feeding and growing stronger for their fall migration to Central America. Although weighing only about 1/8 of an ounce, these tiny flying jewels cross the Gulf of Mexico each fall to return to their winter habitat in southern Mexican and northern Panama. And, despite the myth that has developed about their migration, alas they donot hitch a ride across the Gulf on the backs of larger migrating birds.
These fall migrations have been taking place for millennia and migrating butterflies and birds have learned to look for species of flowers and other native plants that will help them survive and persevere during their staggering southward journeys. Those of us who enjoy sharing our world with them can do much to help them along their way. Just as many Midwesterners have started growing milkweed and nectar plants for the Monarch butterflies, so too can we help other migrating wildlife. For example, warblers also migrate south at this time of year, flying at night and settling in the branches of trees to feed and nap a bit during the day. We can help protect and assist migrating warblers by protecting large, mature trees for these tiny birds to rest in during their migration. But it’s also critical to plant and care for young trees now so there will be large, mature trees decades and centuries from now.
So, as you dig out your warm sweaters, gather your rakes and tune-up your snow blower, take time to offer a fine farewell to our friends of summer. Soon our feathered friends from the North who spend the winter with us, such as the dark-eyed junco (Junco hyemalis), will be outside our windows, mingling with the chickadees, nuthatches and other birds who live among us year-round. And, before you know it, the garden catalogs of January will arrive so you can start to dream and plan what you will plant next spring to help the jewels of the sky who fill our Septembers with such wonder.
August 26, 2016 - Valuing Mature Trees
A longtime volunteer shared with us recently that the “tree tags” we place on mature trees — to demonstrate a tree's lifetime benefits — have had a huge impact on her. She had no idea that one mature tree could provide so many benefits to our homes, neighborhoods, and communities and that those benefits have a cash value.
For example, one large black oak on the Brucemore grounds (in Cedar Rapids, Iowa) was valued at providing $81,580 in benefits in the form of increased energy efficiency, stormwater retention, increased property values and more. Estimated to be more than 100 years old, the oak is in outstanding condition and should continue to provide growing benefits for many years to come.
With pests such as emerald ash borer, as well as storms and ongoing clearing of trees and natural areas for development and cropping, we continue to lose mature trees at an alarming rate, which is worrisome because mature trees provide us so many important benefits.
Trees and native plants benefit water quality by taking up rainfall and reducing erosion and pollution from field and lawn runoff. Urban trees can reduce annual stormwater runoff by 2 to 7 percent, and a mature tree can store 50 to 100 gallons of water during large storms.
A study conducted by Trees Forever with the help of Coe College students concluded that for every $1 spent on street trees in Cedar Rapids, taxpayers receive $4 back in benefits. The more healthy, mature street, park and private trees a city has, the more benefits we all receive.
And trees are homes, too. Just one mature oak can support up to 500 species of butterflies, moths, bees, birds and mammals, all while also cleaning our air and water and providing shade. We must do our best to preserve existing mature trees and habitat whenever possible during new construction and development.
July 13, 2016 - Roadside Beauty
How Midwesterners view the way that roadsides are managed is rooted deep in the region’s culture. There are those who want the roadsides to be mowed, with a uniform look that reflects the Midwestern pride in tidy homesteads and “clean” fields that are free of weeds.
But there is another side of the Midwestern ethic that values things that have purpose and serve a function. The expression of this along our roadsides is the use of native grasses, flowers, trees and shrubs that are out there working for us.
The deep roots of native plants and grasses can extend many, many feet deep into the soil. These extensive root systems hold soil in place rather than letting it wash into local creeks and rivers. The roots also help the soil absorb rainfall to reduce flooding on the road and downstream. And these plants can capture pollutants that wash off fields and roads, thereby cleaning the water that we eventually drink.
The trees and shrubs you see along roads are doing their part as well. Sometimes trees and shrubs are planted to act as living snow fences, slowing snow so it drops into the ditch instead of across a road. Trees can also be planted in progressively shorter intervals to provide drivers with visual clues that they need to slow down as they approach an area with reduced speed limits, such as a school or town.
All of these native plants also offer habitat for beneficial insects, such as pollinators, and to songbirds and gamebirds, both of which are important to many people in our region.
And to top it off, native plants along roadsides help save tax dollars by reducing the need to mow mile after mile of roadside once the plants are established.
Luckily, there is a proven way to satisfy the Midwestern preference for the tidy as well as the Midwestern inclination toward things that are functional and adaptable. Researchers have shown that native plantings that have mowed edges suggest at a subconscious level that the area is cared for and intentional. Of course, education—whether through signage, outreach to landowners or elected officials, or written pieces such as this blog post--can be helpful, too.
So the next time you are driving along roads in the Midwest, pay attention to what is growing there. What do you think the plants you see say about the people who call that place home?
May 15, 2016 - May is Wildflower Month
Many of the plants that bloom in our woodlands in April and May hug the forest floor, drinking in the sunshine before the trees fully leaf out and shade them. These woodland flowers cannot be fully appreciated from a distance. Many of them require a more intimate encounter and an eye that sees the subtle beauty of the immediate.
And it is not just their beauty that requires our attention and respect. The spring-blooming woodland wildflowers provide some of the earliest pollen and nectar sources for pollinators. For example, Dutchman’s Breeches (Dicentra cucullaria) are pollinated by queen bumble bees searching for nectar as they emerge from hibernation. Spring Beauties (Claytonia virginica) are visited by many kinds of bees, including honey, bumble and mason bees. And Solomon Seal (Polygonatum biflorum) are buzz-pollinated by bumble bees--usually the small worker bumble bees that represent the first offspring of that year’s colony. Photo at right: Bumble bee on Dutchman's Breeches (photo credit Meredith Borchardt)
Fascinated by the spring migration of birds? Many of the wildflowers of our woodlands help the birds that return to your neighborhood each year or are just stopping by to rest on their way farther north. The May-apple (Podophyllum peltatum) often forms large colonies on the forest floor that can shelter flocks of birds as they migrate through. Wild Columbine (Aquilegia canadensis) is a favorite source of nectar for returning hummingbirds. And, of course, many birds that feed on insects, or feed insects to their young, rely on the insects that visit spring wildflowers.
As if beauty and birds aren’t reason enough to treasure the plants that grow beneath the trees of our woodlands, researchers have demonstrated that these plants help reduce stream pollution by retaining nutrients in the soil. Researchers at Iowa State University found that woodland wildflowers such as wild ginger (Asarum canadense reflexum), Virginia waterleaf (Hydrophyllum virginianum), and Virginia bluebells (Mertensia virginica) are effective at capturing and storing nutrients.
While some people see the trees and all the green plants in the woods and think all they see is as it should be, a healthy forest ecosystem requires a lot of care and management to keep it healthy and robust.
