Protecting Michigan Turtles

By Abby Pointer, MNA Intern

In the state of Michigan we are lucky to be the home of multiple turtle species, from the common snapping turtle to the red-eared slider. With such a diverse potential for habitat, turtles can live in woodlands, grasslands, lakes, rivers, wetlands, and even cities. Unfortunately, some turtles with more specific needs are suffering from habitat destruction and loss, making their survival a bit more difficult. Three of these critters are species of concern, which dictates that they are in need of specific conservation actions, and one species is currently threatened, which is a warning that it is on the brink of becoming endangered. An important way to help conserve these turtles is education, so let’s take a minute to learn how to identify these turtles and their habitat.

Eastern box turtle

The first of the four is the eastern box turtle, one of the three species of special concern. Recognized by a helmet-shaped shell with yellow and orange blotches, the eastern box turtle prefers moist, deciduous woodlands with sandy soils and ravines or slopes. Historically, they have been common in eastern Lake Michigan and western Lake Erie woodlands but numbers are steadily decreasing.

Blanding’s turtle, on the other hand, prefers more wetland habitat, a habitat itself that is in need of conservation effort. These turtles can be found in shallow weedy waters of wetlands, marshes, and swamps. Their shell is tall, domed, and of darker coloration. The rest of the skin is also darker, and the under part of its body and neck is a bright yellow color.

The Wood turtle prefers low disturbance, and because of that the species is now quite uncommon in the Great Lakes region. For most of the year, they reside in sandy bottom streams or rivers, but are terrestrial in the summer. Shells of wood turtles are brown or grayish brown, that sits low and central on their back. Their head, legs and tail are typically black while the softer parts of their body are a yellow color.

 

While the previous three turtles were species of special concern, the Spotted turtle is the one threatened turtle in Michigan. These turtles live in clear shallow water with mucky bottoms and much vegetation. Their populations are typically isolated and are found surrounded by areas of unsuitable habitat, and are unfortunately quite rare in the Great Lakes region. These turtles, like their name, are distinguished by small bright yellow spots on their dark colored shell.

Many of the turtles mentioned above are threatened by wetland drainage and other types of disturbance such as pollution, nest predation, and over-harvest. One of the best ways you can help protect these species is by helping joining a conservation organization, such as the Michigan Nature Association, that supports efforts to protect their depleting habitat.

Invasive Species Spotlight: Japanese Stiltgrass

By Abby Pointer, MNA Intern

Microstegium_viminium_specimenAt first glance, Japanese stiltgrass appears to be an innocent, pleasant-looking plant. Most wouldn’t even give the grass a single thought if they were to encounter it. In a sad reality, however, that “irreproachable” grass is quite the opposite. This invasive species chokes out the wildlife around it, and grows and spreads at an alarming rate. It decreases biodiversity and forces animals and plants alike out of their natural habitats. It is widely thought that this species is among one of the most dangerous invasives, as it has spread throughout the country very quickly in relatively little time.

The grass was introduced in Tennessee in the early 1900s through its use as a packing material. It is native to Japan, China, central Asia, and India. Since then, it has spread rapidly to the east, and has started to make its way into the Midwest.

Like other invasive plant species, Japanese stiltgrass is spread with the unintentional aid of humans and animals. The small seeds latch onto fur and clothing, or are carried by the wind. The seeds can survive for up to five years in the soil. The stiltgrass can cross and self fertilize, producing up to 1,000 seeds per individual plant. Most animals avoid eating the plant, leaving it to grow with little to no controlling factors.

The stiltgrass is most often found in shaded areas that are often subject to soil disturbances such as tilling or flooding. It is found along roadways, in floodplains, along hiking paths, as well as in damp woodlands. It’s not picky when it comes to the acidity of the soil it inhabits, though it prefers the soil to be fertile. When in direct sunlight, it doesn’t grow as quickly as it normally could. Its growth is also slowed when near stagnant bodies of water. The grass can also infiltrate residential areas, and is often found in flower beds, lawns, and parks.

JPSGrass identification is notoriously tricky, but thankfully, Japanese stiltgrass has a variety of distinct features for people to identify it by. First off, each plant can have multiple weak stems that branch near the base of the plant. The stems are smooth, and can be green, brown, or purple. The leaves are two to four inches long, and about half an inch in length. They’re pointed on both ends, and have off-centered, silver, ridges. They are widely spread out on the stem. The roots are thin, and weak. They are very easy to pull out of the ground because they do not grow very deep into the soil. Aerial rootlets are present along nodes near the base of the stem – these stilt-like features are what gives the plant its common name of “stiltgrass”. The plants grow flowers in late summer through early fall, and the flowers have a few spikes.

Japanese stiltgrass can get up to about six feet tall, though many plants tend to be between one to three feet in height. The taller plants usually prop themselves up on other plants or trees, or they lay flat against the ground. During the autumn, the tops of the plants turn purple or brown, and in the winter the thatch turns an orange color.

While keeping Japanese stiltgrass under control and preventing it from spreading further may seem like a daunting task, it is undoubtedly a necessary one for the well-being of many ecosystems. Within recent years this invasive has spread to northern Indiana, and last year it was found for the first time in Michigan, in Washtenaw County. Be sure not to get it confused with common look alikes such as Whitegrass, Nimblewill, Basketgrass, Deer tongue, Smartweed, or Crabgrass!

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.

3rd - Colwell, Roberta - Green FrogStepping onto the sanctuary land is like entering a whole new world, kept away from the commotion of everyday life. 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!
