Meet Our New Lincoln Highway National Heritage Byway Coordinator

by Mike Kellner | Oct 3, 2022

On the surface Prairie Rivers of Iowa’s new Lincoln Highway National Heritage Byway (LHNHB) Coordinator Jonathan Sherwood radiates a friendly, yet quiet demeanor. Already it has become apparent he knows how to bring people together as a great listener with empathy and thoughtfulness. Despite his calm exterior, digging deeper, we have quickly learned he has a deep passion for historic preservation and community development.

Something else everyone should know about Sherwood is that he was born for his new role being from, and now once again living in, the Lincoln Highway community of Nevada, Iowa. Some of his earliest memories include enjoying spirited parades during Lincoln Highway Days. “Nothing compares to the quality of life in Central Iowa and growing up one house off the Lincoln Highway,” he relates.

In his new role, Sherwood is taking on the often gargantuan task of bringing together governments, businesses, civic organizations, tourism officials, history buffs and transportation enthusiasts together as Prairie Rivers continues a new chapter of Byway management. According to Prairie Rivers of Iowa Executive Director Penny Brown Huber, “Jonathan is an excellent listener which is a skill that helps when reaching out to so many different community leaders.”

As byway coordinator, Sherwood’s duties will encompass working across the 13 Iowa counties and 43 towns that stretch along the Lincoln Highway in Iowa, river to river, east to west from Clinton on the Mississippi to Council Bluffs on the Missouri.

He is committed to restoring, protecting and preserving the cultural and natural resources in Iowa. “This work provides the opportunity for me to work on some of the things I’m most passionate about, people, transportation, and the environment,” says Sherwood.

According to Huber, some of the reasons Sherwood was hired for the position include his degree in community and regional planning from Iowa State University and his previous work experience in transportation and rural communities with an emphasis on geographic information systems (GIS). “His time working with communities to utilize trails for economic development activities made him an excellent fit to be the LHNHB Coordinator,” states Huber.

Sherwood is a member of the Institute of Certified Planners (ACIP) and is currently pursuing a Master of Landscape Architecture (MLA) degree at ISU. He is replacing Shellie Orngard as the new LHNHB Coordinator who is now focused on Prairie Rivers special projects including an evaluation of properties along the Lincoln Highway that are on, or should be, on the National Register of Historic Places. To contact Sherwood email him at jsherwood@prrcd.org.

In his spare time, Sherwood enjoys gardening and traveling to Iowa’s state parks. Be sure to keep an eye out for him along the Byway!

A Mother’s Love: The Race to Provide

by Jessica Butters | Aug 28, 2022

A speck of sunlight warmed the face of a mother, causing her to wake and stand up. She took a few steps toward the sunlight, letting it warm her cold legs in her tunnel. Looking back at the wall of her nursery, she knew she had limited time to finish her work. Behind that wall was a row of rooms, one for each of her eggs. Each nursery room was provisioned with pollen and walled off from the others, providing a safe place to hatch, overwinter, and hopefully emerge next year. Her antennae started twitching excitedly. She tried beating her wings; they buzzed. She was warm and ready for another day’s work.

She cautiously peeped over the lip of her nest entrance. She was a metallic green sweat bee, and just last week she watched as a parasitic bee invaded one of her neighbors’ nests, ending the hope of a future generation from that mother. To keep all her efforts from being in vain, she had to leave and enter her nest in complete secrecy. She scanned the area around her, checking for someone perched on the tops of rocks or hidden in the shaded spaces between grass stems. So far so clear. She stepped out of her nest, allowing the sun to warm her entire body. Looking around once more, and seeing no sign of threat, she zipped off to start her chores.

Gathering pollen was her favorite chore. She had already started a new nursery cell; all there was left to do was to lay an egg and provide a provision of food. Using the sun as a compass, she navigated to a large patch of gold that she had seen yesterday. The yellow rays of one unoccupied flower caught her eye, and she flew into its center, landing on a blanket of brown bristles topped with yellow tufts of pollen. The buzzing of other insects at neighboring flowers reverberated in the air around her, and caused the flower to tremble even more in the breeze. The air was slowly growing cooler each day. It was taking her longer and longer to warm up enough to fly in the mornings. The frantic buzzing of other insects confirmed a sense of fear she didn’t quite understand. She sensed that she must hurry.

Thinking of her young ones back at the nest, she worked as quickly as possible, picking up pollen and snatching a mouthful for herself every now and then. As she moved across the flower, she let her body brush against as much pollen as possible. She paused periodically to comb this pollen from her abdomen, head, and feet to tuck it onto her back legs where she had thicker, hooked hair that was much better at holding pollen in place. The sun shone on, warming her even more. Through the race to gather and provide for her family, it was nice to be out in the sun and surrounded by velvety gold rays. The bristled brown underneath felt good on her feet and belly. Once she was through gathering here, she remembered a bright purple area that had looked promising.

After a while, the little sweat bee had as much pollen as she could carry. Pushing off the sunflower, she flew back toward her nest, only pausing once for a breath on a stand of purple flowers. Back on the ground, she felt around with her antennae until she found her own nest entrance. She peered inside her dark nest. All was quiet, just how she left it. She glanced behind her. No one had seen her; her family was safe.

As she pulled pollen off her legs and rolled it into a loaf, she had a sense that this may be the last nest she would finish. She felt much more tired compared to a few weeks ago. She was particularly proud of this nest: it was in a well-hidden location, its walls were smooth, and she had a good mix of pollen from different flowers within each loaf she had made for her children. Although she would never get to meet them, she was glad they would have all the nutrition they would need to start a successful life. She hoped they would find the yellow and purple flower patches. She grew more tired. Maybe one more pollen collecting trip before she turned in for the day.

Container Gardening for Pollinators

by Jessica Butters | Aug 1, 2022

How to Support Pollinators with Limited Space

Most pollinator garden guides are for those who have the space, time, and energy to implement a large garden into a backyard or front lawn. Those of us who rent, have small yards, or can’t commit as much time to gardening are normally left out of the conversation – until now! Apartment dwellers and busy homeowners alike have the ability to provide important resources to pollinators through container gardening! Below we outline some reasons why container gardening is important, give some gardening tips, list fantastic native pollinator plants, and provide links to inspiring resources to help turn your porch or balcony into an beautiful pollinator habitat!

The Importance of Container Gardens

Container gardeners fulfill unmet pollinator needs

If you live in a large, uniform area such as a rental complex or a grass-turf suburbia, it is all the more important to provide native habitat! These areas are full of concrete and frequently-mowed grass, making the area inhospitable to most pollinators. By growing a container garden, you contribute an important “stepping stone” for pollinators by providing them with nectar and pollen resources to help them move through your neighborhood.

Balcony gardens are inspiring

Have you ever looked at your neighbor’s porch or balcony and been inspired to add solar lights or a hammock to your own? You can do the same by inspiring your neighbors to start a pollinator garden! Apartment balconies are highly visible, giving you the perfect opportunity to showcase your efforts and spread the word about how your neighbors can help pollinators. The more people providing native habitat in your area, the more likely you will be able to start enjoying butterfly and bee sightings!

They are great learning experiences

Everyone starts somewhere. It can be daunting to start growing plants you are unfamiliar with. Additionally, you may be aware of topics surrounding native and nonnative plants, invasive plants, local ecotype… the list goes on. How “correct” do you have to be to get started? In my opinion, it is a great loss to miss out on a learning experience about native plants due to the fact that you were afraid of not being “correct” enough. The more you try, the more you learn, and pollinators desperately need more people learning about them and the plants they rely on if they are going to survive in the future. Also, because you will be growing plants in a container and trying to incorporate native plants, it is less likely that a plant would escape its container and cause issues. Caution is important and it shows that you care, but don’t be afraid, do what you can, and use this article as a starting point to get a pollinator container garden going!

Container Garden Tips:

Plan Ahead and Make Room

Start planning for next year’s container garden now, so you can get a jump on ordering seed or plugs! Also, use pots measuring about 18 inches wide and 18 inches deep or larger; prairie plants have deep roots.

Think Diversity

Provide a range of bloom times, colors, flower shapes, and plant structures to support as many pollinators as possible. This also provides you with a beautiful, dynamic garden space throughout the growing season. It may also increase your chances at seeing polliantors!

Grow Native Plants

Incorporating plants native to Iowa is fantastic, but utilizing native plants with a local ecotype is even better. Local ecotype means that the plant (and its resulting seed) was grown within a certain area, making it well-adapted to that area. To find local ecotype seed, find nurseries and greenhouses within 150-200 miles of your home, and ask where they source their seed.

Provide with Patience

It can take a few years for a native plant to bloom if started from seed, whether planted in a pot or the ground. This makes creating a native garden very rewarding! If starting from seed sounds daunting, plan your plant list now, and use plugs instead of seeds for the next growing season. This route is more expensive but gives you a nearly instant pollinator garden.

Heel and Save Seeds

Successfully overwintering grown native plants in pots is difficult; research the term “heeling” for info on how to overwinter pots with more success, or overwinter them in an unheated garage. You could also donate your potted plants to someone who can plant them in the ground in early fall. Remember you can collect seeds from your plants to use next year.

Leave it for the Bees

In the fall, leave potted plants outdoors until November and do not cut back dried-up vegetation. Place pots back outside in April, and only cut back stems and leaves when nightly temperatures consistently reach 50°F. Doing this increases the survival of any pollinators that may have decided to nest in your plants; it gives them a chance to emerge and start the next generation of pollinators!

Pollinator Plants for Container Gardens:

The following plants are mainly tallgrass prairie plants native to Story County, Iowa, and grouped by sunlight requirements. Remember to never take plants from natural areas in an attempt to transplant them into your garden. Natural and wild areas are increasingly scarce, making the plants in them vitally important to pollinators and other wildlife!

Full Sun:

The following native plant species are for balconies and patios that receive full sun during the day. They are also mostly tolerant of drier soils, which is handy as container plants in sunny areas tend to dry out faster than shady areas.

Marsh Rainbow Arch Bridges

by Joyce Ausberger | Jul 6, 2022

During our April meeting while discussing the bridge in Tama, we had a conversation about James Marsh and his Rainbow Arch Bridge designs along the Lincoln Highway. So I reached out to our resident experts, Bob and Joyce Ausberger for a history lesson on these bridges and their significance to the Lincoln Highway.

James Marsh was the builder and promoter of several Rainbow Arch Bridges. He graduated from Iowa State University with a degree in Mechanical Engineering. His company was N.E. Marsh & Son Construction Company in Des Moines. The bridge designs were formed by the conjunction of new technology, and reinforced concrete. The previous stone bridges were more expensive and labor-intensive.

By 1893 Marsh had constructed numerous bridges in Iowa – a three-mile elevated railroad structure in Sioux City and three bridges in Des Moines. Similar bridges were built in Montana, South Dakota, Minnesota, Colorado, and five other western states.

Numerous single-span concrete arches can be found in rural Iowa, but multiple-span examples are rare. Moreover, among those concrete arches remaining in the state, the Eureka Mill Bridge is one of the earliest such arch structures designed by the state highway commission. We are fortunate to have these existing samples of these two types of bridges still remaining

The Incredible Diversity of Iowa Moths and Butterflies

by Jessica Butters | Jun 29, 2022

Did you know that National Moth Week is celebrated in July? Read up on Iowa’s native moths and butterflies to be ready to celebrate Moth Week right, from July 23rd to 31st!

Iowa is home to about 110 butterfly species, and over 2,000 moth species! Butterflies and moths are related: both are in the insect order Lepidoptera, which roughly translates to “scaled wing”. Most of us think of moths as the ugly stepsisters of butterflies, but this is not true! In fact, I would call moths the sleeping beauties of our natural world (they are beauties that are often active while we sleep). Don’t continue to sleep on the incredible beauty of Iowa moths, and get to know our butterflies better!

Giant Silk Moths
If you’re lucky enough to have seen a luna moth, then you’ve seen a member of the giant silk moth group, called the Saturniidae family (Saturnia is the daughter of Saturn in Greek mythology). This group also includes the cecropia moth, named after Cecrops, a half-man-half-snake king in Greek mythology. If you squint at the top outer corner of the cecropia moth’s front wing by the dark eyespot, you can see what appears to be a profile of a snake’s head. Lastly, the luna and cecropia moths don’t eat as adults – they have no mouths! They only eat as caterpillars, which is common in the mysterious world of moths.

Hawk Moths and Hummingbird Moths
Aptly named, these moths look and fly like humming birds, hovering while drinking nectar with their straw-like mouths (called a proboscis). Some also mimic bumble bees, like the snowberry clearwing pictured on the right! Belonging to the family Sphingidae, these moths can be diurnal (day-active) or nocturnal (night-active). Some species don’t eat as adults. For those that do, they are important pollinators for prairie orchid and primrose species!

Owlet and Underwing Moths
Most of these moths are the experts of disguise, using drab colors on their front wings to blend in with bark and dead leaves. They are in the family Noctuidae, the largest family of moths in North America. Underwing moths, however, have a secret weapon: their back wings can have bright colors that hide under the front wings, and can be flashed to startle a predator during escape!

Tiger Moths
When wooly bear caterpillars mature, they are called tiger moths, also known as the family Erebidae. These moths can have bright colors decorated with geometric lines, consequently nicknamed “tiger” moths. I saw the tiger moth pictured here the last week of June at Ada Hayden park! This species of tiger moth is called the “reversed haploa moth” due to the fact that it has two color variations: either geometric lines on the front wings with plain white back wings, or the reverse: plain white front wings with geometric back wings.

Brush-footed Butterflies
The family Nymphalidae, commonly called the brush-footed group, is one of the most popular groups of butterflies with monarchs, regal fritillaries, and painted ladies included in its ranks. Why are they called brush-foots? Their front legs are very small, and kept close to their body (similar to t-rex dinosaurs in my opinion). These front legs aren’t used for walking and are basically reduced to little “brushes”.

Swallowtails
While one of the most entrancing butterflies, swallowtails are tough; they overwinter here in Iowa! As caterpillars, this group (which is the family Papilionidae) spin their chrysalises and wait out the winter under dead leaves, giving us another reason to leave areas in our yard undisturbed this fall. The caterpillars of this group can just as awe-inspiring, with some having bright green colors, or eyespots that can make them look like snakes to scare predators away!

Whites and Sulphurs
This group of butterflies has a charming behavior; they like puddles! Belonging to the Pieridae family, these butterflies are the most likely to be found in a “puddling” group, sucking up extra nutrients in the water. Adult butterflies appear white, yellow, orange, and sometimes have black markings. One of the coolest butterflies in this group is the Olympia marble, a species of special concern in Iowa due to declining numbers. Just look at its metallic markings against snow-white wings!

Blues, Coppers, and Hairstreaks
These tiny butterflies are also called gossamer wings, due to the beautiful shimmer that reflects off their wings! These butterflies are a part of the family Lycaenidae, and also love visiting puddles, so don’t let their looks fool you; they are hardcore. Continuing that thought: the species Satyrium edwardsii, or Edward’s hairstreak, has some wild behavior as a caterpillar. At night it feeds on oak leaves, and during the day it rests in active ant nests for protection! This species is also a species of special concern in Iowa due to declining numbers.

Skippers
If you can’t tell if an insect is a butterfly or a moth, you may be looking at a skipper. Skippers are in the family Hesperiidae, and have chunky bodies with hooked, hockey-stick-shaped antennae. They appear carefree as they skip through the air. From the side, their wings give them a triangular, shark-fin shape. Out of the two butterfly species in Iowa considered endangered, one is a skipper, called the Dakota skipper. It requires high-quality prairie remnants, a habitat extremely hard to find in Iowa.

While many people love butterflies, these insects don’t always receive the respect they deserve being diverse and important wildlife. They are more than nature’s gems-they are important pollinators that have fun behaviors to appreciate! Moths are often forgotten, despite the fact that they can be bigger and more colorful than many butterfly species, and have the coolest adaptations, such as flashes of color and mouth-less adults! The world of moths and butterflies is not just a pretty one; it’s a wild one!
