Annual Monitoring in Effect at the Hart Plant Preserve

Hart NS signBy Lauren Cvengros, MNA Intern

The Donald E. Hart Plant Preserve is located in Benzie County in the northwestern part of the Lower Peninsula by Crystal Lake. It is a cedar swamp located on the Betsie River, donated by longtime MNA Members Donald E. and Marjorie A. Hart. The sanctuary is located within 45 minutes of Traverse City and is an incredibly beautiful spot thick with trees and full of frogs, salamanders and other amphibians. This sanctuary protects nine acres of conifer swamp and 255 feet of river front.

The land is completely untouched by humans, so the natural features are allowed to flourish. Although the land is safe from human influence, there are a few invasive species including reed canary grass and wild parsnip. The work the Michigan Nature Association does to protect the plant preserve is imperative to maintain and restore the native wildlife. The swamp area in this sanctuary is a Betsie River Near NW Corner 4common dumping ground for brush clippings and trash, so MNA’s efforts in annual monitoring is crucial. If you go to visit this sanctuary, you will notice the stillness of the untouched land, left in peace for the creatures who live there to thrive. This type of environment is becoming more and more scarce and if not properly taken care of there is a threat of habitat destruction and species extinction. The monitoring efforts conducted allow places such as the Hart Plant Preserve to exist.

The present species are vibrant, mostly frogs and salamanders, of whom can be seen abundantly around the sanctuary. The preserve is home to all types of plants such as birch trees, pine trees, dogwood, honeysuckle, ferns, vines, and more. The thickly wooded forest and green covered floor of the sanctuary provides a prime example of a little slice of nature you can enjoy in Benzie County.

Celebrate National Pollinator Week this June 18 – 24, 2018!

By Lauren Cvengros, MNA Intern

The phrase “Save The Bees” is being thrown around a lot these days, but what does it really mean? It’s a phrase meant to inspire people to protect these little creatures that help pollinate our plants; but it goes beyond just bees, all pollinating critters are in dire need of protection.

pollinator week 2018Eleven years ago, the Senate approved Pollinator Week to be held June 18-24 to raise awareness for the declining pollinator presence in our ecosystem. Pollinator Week is an international movement to celebrate the ecosystem services that bees, bats, butterflies, birds and beetles provide to us. These pollinators are responsible for producing one-third of the food we eat by helping plants reproduce. Do you like to enjoy a yummy chocolate bar, crave avocado toast for breakfast or carve pumpkins on Halloween? Those are all made possible by our pollinating friends. Pollinators don’t just provide use with honey – if we didn’t have them we wouldn’t be able to eat fruits or vegetables, drink coffee, or add spices to our food. Even dairy would be limited as the food cows eat is available due to pollinators.

Plants are asexual, meaning they need a little help to reproduce. The pollinators carry the pollen from the male plants to the female plants so the females can produce seeds, fruit and the next generation of plants. Wondering what exactly these pollinated plants bring us?

They’re responsible for:

  • provide the fruits and nuts we eat,
  • give us half of the world’s oils, fibers and raw materials,
  • prevent soil erosion,
  • increase carbon sequestration (stores carbon that would otherwise be emitted into the atmosphere causing global warming),
  • support other wildlife;
  • protect against severe weather and promote clean air.

How you can help?

There are things you can do at home to participate in Pollinator Week.

  1. Make room for pollinators at your home. You can give them a place to live by This sign is in someone's front yard in Oakland, CA.planting gardens. Live in a city? Not a problem, pollinators love plants in any setting. Make sure you are planting the correct plants. You can find a guide to which plants are best for pollinators by visiting http://pollinator.org/pollinators#fn.
  2. Buying local is another way to support our pollinators – opt for buying in season, organic honey, fruits, spices and vegetables from a trusted source such as a farmer’s market.
  3. Spread the word! Let others know about Pollinator Week to raise awareness and help protect our pollinating friends.

Protecting Wetlands

Wetland - Abby Pointer

We celebrated American Wetlands Month this May! Extremely productive ecosystems, wetlands can be found in all extremes, from the tropics to the tundra, on every continent except for Antarctica. A little closer to home, Michigan wetlands provide important habitat to many species of waterfowl and fish, which play a vital role in our recreation and tourism industry, as well as our economy.

A wetland is an area where water covers the soil and is present all year or for varying, yet predictable periods of time. Wetlands form for a variety of reasons, whether from a permanent body of water, precipitation, or seasonally from rain or snow. This soil, described as hydric from its saturated quality, becomes anaerobic, or without oxygen. Therefore, the bacteria that reside there cannot use oxygen to respire, and use carbon or nitrogen, giving wetlands a high concentration of these particular molecules to create a unique ecosystem.

This hydrology, the water saturation of the soil, of wetlands is a major factor in determining the type of soil that develops and the organisms that the environment can support. Since wetlands are versatile ecosystems, many types of both terrestrial and aquatic organisms can live there. In Michigan wetlands, you are likely to see a landscape covered in various sedges and rushes, and in the spring little mallard broods, perched Bobolinks, as well as a booming population of sandhill cranes!

These waterfowl, among many others, find sanctuary in wetlands, as they provide habitat and food for each year’s new brood of ducklings as well as a “rest stop” for migratory birds. About one-third of the United State’s endangered species call wetlands their home, from the American crocodile to many types of orchids! Wetlands also serve an important ecological purpose, such as acting as a buffer to prevent pollution from entering the water system, stopping widespread flooding and holding those excessive flood waters, and controlling erosion along our beautiful Michigan shoreline.

Unfortunately, wetlands are becoming increasingly rare due to human actions. Between filling and draining to make room for land for agriculture or development, building dams or dikes, and excessive logging, these detrimental actions have given rise to programs to restore these endangered ecosystems.

Michigan is one of only two states to have a federal wetlands program and is working toward continual restoration of these lands. Methods involve preventing the aforementioned human actions as well as taking measures to remove the tiling that drains water. This special attention from MNA, MDNR, DEQ, and other conservation groups will help guarantee that we can continue to enjoy the beauty and habitat our important wetlands provide!

Estivant Pines: A Living Museum

The Estivant Pines Nature Sanctuary, protecting the largest remaining stand of old growth white pines in Michigan, celebrates its 45th anniversary.

By William Rapai

Time passes slowly at Estivant Pines.

Nobody knows that better than Gary Willis, a forester with the Michigan Department of Bertha and groupNatural Resources and former assistant professor at Michigan Technological University. Willis knows this place better than most people. When you see this preserve through his eyes you begin to understand that the best way to truly appreciate this place is not to consider time in hours, years, and decades but in centuries, periods and eras.

Estivant Pines is the Michigan Nature Association’s 510 acre sanctuary in the Keweenaw Peninsula. Despite its remote location—down a pothole-strewn dirt road south of Copper Harbor—it is one of the organization’s most popular sanctuaries. Every summer, thousands of people from across the United States visit, wandering two looping trails to marvel at white pine trees that stand 120 feet tall.

But there aren’t many visitors to Estivant Pines in the late winter or early spring because the road that leads to the sanctuary is usually under several feet of snow or too muddy to be drivable. However, the period after snowmelt and before trees emerge from dormancy is the best time to see and understand time’s impact by looking down—not up—and closely examining what is and isn’t here.

What is here is volcanic bedrock that dates back to the earliest period of Earth’s history and carbonized tree stumps that are the remains of a cataclysmic forest fire more than 200 years ago. What isn’t here is surprising and confounding. The plant life in the understory is healthy—lots of lichens, mosses, ferns, maples, birches, cedars, spruces, and balsams. Surprisingly, there are few young white pines even though these 240-300 year-old trees have produced millions of viable seeds during their lifetimes.

img 1198Willis gained these insights when he was a forester for the Michigan Nature Association. In the late 1990s he started working at Estivant Pines at the request of Michigan Nature Association’s founder Bertha Daubendiek. Willis was given a unique opportunity to study these ancient trees after a logger accidentally trespassed on the sanctuary and cut a number of the trees along one of the boundaries.

Daubendiek sent Willis out to write a damage report, but during the process he started to see this incident as a unique opportunity to study how these giant trees grew. As he measured the width of the stumps and correlated individual ring-widths he began to understand these trees through the prism of time.

But it’s not just the trees that are measured in time. Much of this sanctuary sits on a high ridge of volcanic bedrock that runs between Annie Creek and the Montreal River that dates back to the earliest period of Earth’s history, some 1.1 billion years ago. In fact, Willis said, other researchers at Michigan Tech have discovered the Keweenaw was once one of the most active volcanic regions on Earth.

It’s difficult to see it from the landscape level, but Willis says if you look at an aerial photo of the peninsula, you can see a series of ridges left behind from that volcanic flow. Those ridges run parallel to the shoreline and curve as the shoreline curves and narrows as it reaches the tip of the Keweenaw Peninsula.

Even though we tend to think of these trees as old, the plant community here is in its infancy, relatively speaking. Plants—trees, shrubs and grasses—established themselves only about 10,000 years ago following the withdrawal of the Wisconsin Glacier.

Tree roots - Brittany AllenMultiple glaciers over the past 2.5 million years left behind a thin layer of soil that can support plant life but generally is not deep enough to anchor a 100-foot-tall tree. To compensate for the lack of soil, most of the pines have grown roots deep into fractures and crevices in the bedrock. Some trees have been lost to windstorms but remarkably few considering that the sanctuary sits at an altitude that varies between 200 and 500 feet above lake level. That altitude leaves these trees exposed to powerful winter winds that blow across Lake Superior. In the winter, this sanctuary can get more than 275 inches of snow in a single season. The combination of heavy, wet snow and strong wind can bring even the hardiest tree down, says Donald Dickmann, professor emeritus of silviculture and physiological ecology at Michigan State University and co-author of The Forests of Michigan. Fortunately, most of the snow that blankets the Keweenaw’s rocky ridges is light and fluffy lake effect powder.

Summer brings heavy thunderstorms and gusty winds, and the trees, which tower above the hardwood canopy, are sitting ducks for lightning strikes. One of those lightning strikes more than 200 years ago might have been the spark for a fire that ravaged this area and set the stage for the Estivant Pines as we see them today.

Those carbonized tree stumps and little bits of charcoal strewn across the landscape point to a potent wildfire that swept through the area in the late 1700’s. Willis said it likely wiped out most of the white pines that had been standing on that spot perhaps for centuries. Just as the towering, mature pines today prevent the young pines from growing underneath, those earlier pines prevented any new ones from growing beneath them. It’s not that these trees are refusing to reproduce; it’s just their reproductive strategy. Barring a major fire, disease or insect threats, these pines could be here for another 300 years before they reach the end of their natural lifecycle. As that happens, the maples, birches, spruces, and balsams that make up the understory will continue to grow and mature and create a thick new canopy 50 feet or more under the tops of the pines. As those trees mature and die, fuel for a future fire will continue to build up on the forest floor, waiting for a spark.Marianne Glosenger - Estivant Pines NO WATERMARK hi res

When that fire eventually arrives, the pines’ continued existence will depend on its intensity. A moderate fire may not cause any damage because the old trees are protected by a thick layer of bark. But if the fire is intense enough the heat will fry the layer under the bark that transports water and nutrients up the trunk. That will kill the tree even if the fire does not reach the top branches. If that happens, the tree, knowing that it will soon die, will put all its energy into seed production. The year following the fire, massive amounts of seeds will cover the now-bare, ash-covered soil and thousands of new white pine trees will germinate if there is enough rain.

And the cycle will begin again.

Ancient white pine trees like the Estivant Pines once covered a good portion of Michigan. loggingIn the late 19th century, lumberjacks cut these trees to supply wood for houses, barns, and carriages needed by a fast-growing nation. At the time, it was thought that Michigan had an inexhaustible supply of white pine.

Only a few stands of virgin white escaped the lumberjack’s gluttony—this one, of course, one at Hartwick Pines State Park northeast of Grayling, and another stand on private property east of L’Anse are the three best known. But Don Dickmann of Michigan State says he has found small stands of them in other places in the Upper Peninsula. Those stands, like Estivant Pines, were spared through random chance and, more recently, the passion of local citizens who wanted to preserve these trees for what they represent.

nancy leonard - epines make a difference dayTwo people who have come to deeply appreciate the history represented by these pines are Bill and Nancy Leonard, who organize volunteers and stewards for the Michigan Nature Association in the Keweenaw Peninsula. They work closely with sanctuary stewards Ted and Alice Soldan to maintain the boardwalks and trails. Bill Leonard said that as he’s working he enjoys talking with visitors and is always amazed by how many people from faraway places around the country come to see these giants multiple times.

“It just pulls people back,” Leonard said.

Indeed it does. But those visitors? For now, it seems, they can take their time.

Spring has Sprung?

By Abby Pointer, MNA Intern

As usual, Michigan is having a little bit of trouble deciding when it wants to transition into springtime. Don’t let the occasional snow shower worry you, there are a few sure signs that you can look for to keep up hope that spring is on its way! Michigan’s beloved flora and fauna will bring the sounds and sights of springtime, such as the spring peeper, the American robin, and wild trilliums.

Some music to your ears might be the classic “tinkling of bells” of the Michigan spring peeper. Around early March, when the ground begins thawing, this abundant amphibian species begins its mating season. The peeping you hear is the male frog calling out to potential mates. The more intense the peeping, the more likely the males are to attract their desired female. If you live near wetland areas, such as a damp woodland, marsh, or pond, you are likely to hear these creatures singing away on a warming spring night.

While the spring peepers sing you to sleep, another sign that spring is near is being awoken by the return of migratory birds. The classic harbinger of spring is the American robin, Michigan’s state bird. You might recognize its song from the often repeated whistle of cheerily, cheer up, cheer up, cheerily, cheer up. When the average temperature fluctuates around 37 degrees, the male robins will be the first to make themselves known as they establish territories and begin feeding. Female robins will return a couple weeks later to begin building nests and feeding on worms from the thawing grounds. You’ll hear them start singing as they arrive on their breeding territories!

Another bird that is usually a first sign of spring in Michigan is the red-winged blackbird, with some arriving as early as mid-February. Males will sing their song, conk-la-ree from a high perch, awaiting the female response of a series of several chits. These birds prefer wetland areas, so if you are near standing water and vegetation, look out for these birds. You will also start seeing more shorebirds and hearing more owls and woodpeckers. The return of these birds from late March through May marks prime bird watching season.

You might notice the budding of trees, and if you look closely some wildflowers are indicators that spring is on its way. The trillium is one that you might see first, a three petaled flower with dark green leaves and pale green accents. The arrival of the wildflowers ushers in the return of pollinators to help speed the spring process along!
