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!

Running for Michigan Moose

The Michigan Nature Association is hosting the Moose on the Loose Family Fun and 5K this Saturday, August 26, 2017 in Marquette, MI. This event is a great way to show support for responsible conservation efforts and wildlife management in Michigan!

After European settlers arrived in Michigan, “moose were pretty much all over” the state, said Rachel Clark of the Michigan History Center to Michigan Radio. Following this, Michigan’s moose population declined as a result of overhunting and habitat destruction from human settlements and logging. Eventually, moose mostly disappeared from the Lower Peninsula.

Moose are currently found in two areas of the Upper Peninsula: the reintroduced population in Marquette, Baraga and Iron counties, and a smaller remnant population in the eastern UP, found primarily in Alger, Schoolcraft, Luce and Chippewa counties.

According to the Michigan Department of Natural Resources, the most recent moose population survey of January 2011, an estimated 433 animals in the western Upper Peninsula were counted. No formal survey of the eastern U.P. moose population has been conducted, but estimated at about 100 animals from field observations and reports from the general public.

Moose populations in the Upper Peninsula have risen and fallen in recent years, and despite a rise in western UP populations, moose are still in need of habitat management and protection, including a balanced relationship with their natural predators, like wolves.

Populations have declined on Isle Royale, but dwindling wolf population to a single pair of adults has allowed moose to thrive, as considerations to import wolves to the island are being made to maintain predator-prey balance and vegetation growth for moose diet.

While currently listed as a “species of special concern,” the US Federal Government considered adding the moose back on the Endangered Species List last year, as this status does not afford the animals or their habitat any protections, and nearly 60% of Minnesota’s moose population has declined in the last decade.

Past attempts to repopulate the Upper Peninsula with moose, which involved shipping moose to the mainland from a large moose herd on Isle Royale, failed to restore previous numbers but succeeded in establishing a moose population, largely due to healthy habitats and increased poaching enforcement, even as poaching threats were low as citizens of the Upper Peninsula were involved with the repopulation project and had adopted the new moose population as their own.

In an interview for MLIVE, DNR Wildlife Division chief Russ Mason said moose populations are declining for a variety of reasons, which include habitat loss, predation and climate change, and because moose are conditioned to live in cold climates, warmer temperatures are putting all moose at risk of overheating, which leads to malnutrition and compromised immune systems.

This summer MNA celebrated Michigan Mammals Week by exploring interesting facts on native Michigan wildlife, including the moose!

Showcase Sanctuary: Dowagiac Woods

Since its establishment as a Michigan Nature Association sanctuary in 1983, Dowagiac Woods has become renowned for its dazzling, weeks-long display of spring wildflowers.  In fact, this in part is what inspired the Michigan Nature Association’s interest; shortly after a member visited the woods in 1975 and noted the abundance of Blue-eyed Mary on a 220-acre forest lot that was for sale, an appeal was made for funding to purchase it. The original purchase has since been expanded to encompass an additional 164 acres.

Every year visitors walk the trails meandering through the diverse blooms, some of which are hard to find elsewhere in the state. However, Dowagiac Woods is a unique example of the value of Michigan’s natural heritage, not just for its famed spring wildflowers, but because it’s a largely undisturbed 384-acre block of high-quality forest habitat with ample biodiversity to support a variety of Michigan-native wildlife, including many rare and some endangered species. Nearly 50 kinds of trees and hundreds of various other plant species, as well as close to 50 kinds of birds, have been catalogued by MNA. These include the Yellow-throated warbler whose clear songs grace visitors with joyful notes, the notorious Pileated woodpecker, and the rare and lovely Cerulean warbler.

Large, intact forest blocks like Dowagiac Woods are vital to the composition of habitats that support an array of wildlife, yet are becoming increasingly rare in southern Michigan as landscapes are fragmented by industry and human use. Additionally, the majority of Michigan’s intact forests reside in the upper half of the state. Thus, as the largest MNA sanctuary in the southern Lower Peninsula and a rare, high-quality example of the natural state of Michigan’s mesic southern and southern floodplain forests, Dowagiac Woods is truly a state treasure.

The ecological importance of biologically diverse plant communities can’t be overstated. Plants form the basis of habitats and aid in performing various hydrological functions not limited to natural flood control, water purification, and the cycling of water. They anchor and enrich the soil, cycle important nutrients, and convert carbon dioxide into breathable oxygen. Forests also act as important carbon sinks by storing large amounts of carbon dioxide. The more diverse the community of plants that make up a community, the more efficiently it can function as a whole and perform these essential services. When biodiversity drops, ecosystems become less resilient against disturbances like disease or fire, because a single species comprises a much greater proportion of the plant community and its decline takes a greater toll.

With the exception of a section of woods that was selectively cut in the 1960s, the majority of Dowagiac Woods has thankfully remained undisturbed. The Michigan Nature Association’s mission is to preserve and maintain pristine areas like Dowagiac Woods. With soil that has never been plowed and trees that have never been clear-cut, it is the closest illustration of how Michigan’s forests may have looked prior to settlement. Visitors are encouraged to walk the trails and take in the rare sights and sounds of the many unique species found there. With careful management, what remains of Michigan’s natural heritage may yet be enjoyed for generations to come.

Frogs and toads: environmentally beneficial creatures

The warm Michigan weather brings about many different types of plants an animals, including amphibians like frogs and toads.

Often after a rain or in a wet, shaded area these critters can be found hopping around.

What’s the difference?

It might be surprising that all toads are considered frogs. Frogs and toads are both amphibians but it’s easy to tell the difference between them by a few key factors. The frog has more smooth, moist skin and longer legs. Toads are more bumpy and warty-looking. Frogs prefer to be around water and moist places whereas toads don’t require wet areas as much and can withstand drier habitats. Toads prefer to crawl rather than to hop from place to place.

Amphibians are defined by a life-cycle that begins underwater. Baby frogs and toads start off as eggs in the water and develop into tadpoles that have gills and can swim. These tadpoles develop lungs and other body parts and, once they have matured, can enjoy life on land.

Toads and frogs breed during the spring and summer and find warm shelter to protect themselves during harsh winter months.

Where do they live?

Frogs and toads live in many places around the world including the rain forest. In Michigan they tend to live in wetlands, wooded areas, beaches and near streams or lakes.

What do they do?

Frogs consume thousands of bugs. This consumption is beneficial for people and the environment, protecting plants, getting rid of pests and maintaining a balance in the food chain and ecosystem. Frogs are also great indicators of changes in the environment as they are sensitive to even the slightest of changes. Their skin is thin and porous so any chemicals or other contaminants to the environment can be shown by a decrease of frogs in more frog-populated areas. Frogs also have provided scientists with compounds for different medicines.

Threats to frogs and toads

Unfortunately there are many threats to frogs and toads throughout the world. Many of these are human-induced problems such as the use of harmful pesticides, habitat loss and pollution to name a few. These actions endanger frogs and toads and can be harmful for the environment which is why protecting them is important.
