Though not always the most celebrated components of a landscape, soils are certainly one of the most important. While plants form the basis of habitats, soils are central in determining which plants can grow where. Consequently, the soil/s of an ecosystem can drastically affect wildlife communities. Soils also play a critical role in filtering fresh water, and have served as the very foundations of civilization. How much do you know about the marvel beneath your feet?
In 1990, Michigan declared Kalkaska sand as its official state soil. It’s relatively infertile owing to its acidic nature, but nonetheless abundant. Despite being one of over 500 soils present in Michigan, Kalkaska sand, so named for one of the 29 counties in which it is present, covers nearly 5% of the state. It can be found in the upper half of the lower peninsula, as well as most of the upper peninsula; but just how did it get there?
The movement of glaciers shaped Michigan’s soils over the course of hundreds of thousands of years into what is known as glacial till. Read more about the process here. In the time since, our soils have undergone many changes to provide support for forests, wetlands, prairies, dunes, swamps, and human agriculture alike. In fact, if not for Kalkaska sand, the coniferous forests of northern Michigan may not exist.
Many of the evergreens that grow in our northern forests, including our ever-important state tree (white pine), are adapted to highly acidic, dry, and nutrient-poor conditions. As such, they rely on otherwise infertile soils like Kalkaska sand. The rare Kirtland’s warbler breeds exclusively in jack pine, and many other well-known species depend upon plant communities derived from Kalkaska sand. In a very real way, we have this unique soil to thank for the natural landscape as we know it today.

Though Lake Sturgeon make look intimidating with their armored, angular bodies, it may be fair to classify them as gentle giants of the Great Lakes. They have lived in this region for around 10,000 years – and have existed for around 136 million. Capable of living for 150 years or longer, these ancient freshwater behemoths are the longest-lived of Michigan’s fish species, as well as the largest, having been known to reach lengths of 8 feet and weigh several hundred pounds. It may technically be female sturgeon which are the longest-lived Great Lakes fish, though, as they can outlive males by as much as a century!
Sturgeon are cartilaginous (non-bony) fish with torpedo-shaped bodies. Instead of scales, they have a kind of armor in the form of bony scutes that cover their bodies. Juveniles may be gray or brown, and appear more angular, while adults tend to be lighter in color and may be gray or olive. The growth rates of Sturgeon are highly variable, but cleaner, more temperate waters and greater food availability offer ideal conditions for these fish to grow large.
Sexual maturity in males is reached anywhere from 8 to 22 years for males and 14 to 26 years for females. Spawning occurs in early spring, usually from April to June, when water temperatures warm to 53-64° F in clean, shallow waters and fast-moving stream rapids. Though they accomplish this impressive feat on average only once every 6-7 years, females lay millions of eggs when spawning – that’s an average of 5,500 eggs per pound of fish!
Once, the range of lake sturgeon extended from parts of Canada down to Alabama, and populations in the Great Lakes region were estimated to have numbered in the millions. However, only remnant populations remain. Historic overfishing in the 19th and 20th centuries nearly led to the extinction of lake sturgeon, as well as pollution and habitat loss from dams and deforestation. They are now listed as Endangered, Threatened, or Special Concern in all but one of the states throughout their range.
Thankfully, Michigan sponsors efforts to protect sturgeon and restore parts of their habitat. Their spawning period is an especially crucial one, as their preferences for shallow waters make them vulnerable. If you happen to come across sturgeon in the wild, count yourself fortunate to have witnessed these living fossils. Learn more about this iconic Great Lakes species from the DNR website.

Beautiful and bold, butterflies have captured the interests and imaginations of people for millennia. Few have been as iconic as the Monarch butterfly. With a historic range spanning over 3,000 miles across North and Central America, as well as the northern part of South America, it is also the most well-traveled. Every spring, millions of these winged wonders make the journey north as far as Canada from their wintering spots in Mexico.
It’s one of nature’s most fascinating phenomena, as no living Monarch has ever made the journey before, and yet they reliably fly in the same direction, year after year. By the time they reach the northernmost part of their range, five generations of Monarchs will have lived, bred and died, leaving their offspring to carry the torch. This final generation, born in late summer, will be the lucky ones to migrate south to overwinter for eight months before beginning the journey north again the following spring.
As many of us have seen, the Monarch is a mid-sized butterfly with a distinctive orange and black wing pattern accented with white spots. Predators should take care not to confuse it with the strikingly similar Viceroy, whose hind wings have a black line that the Monarch lacks. This small difference is important to note, because the Monarch is toxic. Its caterpillars have an equally distinctive appearance, their stout bodies banded with yellow, black and white. Because Monarchs lay their eggs exclusively on milkweed plants, the caterpillars grow up eating nothing else – rendering them their toxicity.
Largely the result of habitat loss, there has been a nearly 90% decline in the population of the Eastern monarch, which is the largest subset of the species and that which carries its migration into Michigan. The loss of habitat includes breeding grounds across the U.S. and overwintering habitat in Mexico, as well as a variety of habitats in which to rest and refuel on their exhaustive journey. This is a grave concern, as pollinators supply 1/3 of the world’s food and 3/4 of its flowers, and apart from being lovely, Monarchs are one of the most common and widespread butterfly species.
Few insects are as beloved as the Monarch. Several initiatives are underway to preserve the necessary habitats to sustain their populations, including the Monarch Joint Venture and Journey North. The Michigan Nature Association is hosting its annual Monarch March Family Fun Run & 5k at Mayor’s Riverfront Park in Kalamazoo on Sunday, October 1 to promote efforts to preserve Monarch habitat throughout Michigan.
Contact Jess Foxen at email@example.com to learn more, or register online. The fee for adults is $25, children $10, and includes a t-shirt and participatory medal. If you’re more into pizza than running, you can also show your support for the majestic Monarch by showing this flyer with your order at Blaze Pizza at 5015 W Main Street in Kalamazoo on September 30th from 3-7pm. A portion of the proceeds will be donated to MNA to support their mission of preserving Michigan’s natural heritage.

As Michigan’s only true terrestrial turtle, the Eastern box turtle might often be mistaken for a small tortoise. It is one of four box turtle species native to the United States. Though an uncommon find, it ranges throughout Michigan’s lower peninsula. It spends its life in small patches of open woodlands, sometimes bordering open fields or wetland. Throughout its life, the Eastern box turtle remains small- to mid-size, growing between 4-8 inches in length. It can be extremely long-lived – occasionally over a century.
Their unique hinged shell allows them to retract their head, tail, legs and arms for full protection. Males and females can be most readily distinguished by the color of their eyes. While males often have red eyes, females have yellow to match the vivid markings on their dark carapaces and bodies. They reach sexual maturity at about 10 years of age. Mature females lay between 3-8 eggs per clutch, and breed at most once per year. During winter, they burrow into mud or bury themselves beneath leaf litter for warmth and camouflage.
Like most turtle species, the Eastern box is an opportunistic omnivore. This means it will eat just about anything food-like that it comes across, including insects, worms, grasses, fruit, mushrooms, flowers, and even carrion and garbage.
Because this species is long-lived and slow to breed, populations can be difficult to exact. However, the species has gained status as Special Concern in the state of Michigan. Habitat loss and fragmentation are primary concerns to populations, as urban and agricultural development extend further into their range and roads cut through much of what is left. If you come across a turtle you suspect to be an Eastern box turtle, admire it from a comfortable distance. If the turtle is found on or near a road, escort it back to safety first!
Fall means back to school, and that new reality brings a seasonal change to the daily migration routes for many Michigan families.
Fall is an especially great time of year to connect kids to nature and the incredible changes that unfold. As students – and their parents – adjust their new clocks and adapt to a new school year, here at MNA we are working with teachers to enrich their student’s classroom learning by using MNA nature sanctuaries as living laboratories. Our schools-to-sanctuaries initiative is creating exciting new partnerships across the state, like the one described by Addison High School teacher Aaron Wesche in this issue’s Q&A (p.33).
Cooler temperatures and decreasing daylight are signals for migratory birds and insects that it is time to leave their northern breeding grounds for warmer winter climes. Some make extraordinary difficult journeys to do so. One of the most astonishing dramas in nature is the annual Monarch butterfly migration from the northern U.S. to a tiny strip of forest in Mexico. Take yourself to a Great Lakes beach or an MNA nature sanctuary with open fields this time of year and wait and watch. You’ll very likely see one of these stunning and fragile beauties flit by as they make their miraculous journey to Mexico.
Sadly, those who have spent a lifetime watching the Monarch migration for the sheer joy of it will tell you they don’t see as many butterflies anymore. Scientists who study the Monarch have confirmed this. In this issue, noted Michigan author Bill Rapai tells the story of how the Monarch migration is now in serious danger of disappearing (p. 18).
The good news is that we can play a role in helping this extraordinary migration (while also helping other declining pollinators). We know that many of our nature sanctuaries provide necessary places for fuel and rest for Monarchs on their journey, but we also know much more needs to be done.
With your continued support MNA will be working to create more Monarch-friendly habitat within our statewide network of sanctuaries; help inspire the next generation to care about Michigan’s natural wonders like the Monarch butterfly through our education programs; and coordinate our work on Monarch conservation with the work of like-minded groups in Michigan, across the Midwest, and Mexico.
