Due to the large scale of this wetland complex and its location within the migratory flyway between the Straits of Mackinac and mainland Canada, a great diversity of birds have been seen using this sanctuary. This addition provides significant wetland habitat utilized by secretive marsh birds and flocks of migratory waterfowl, including black tern, sedge wren, blackburnian warbler, and spotted sandpiper. The Carlton Lake Wetlands Nature Sanctuary addition also hosts beaver, bear, large canids, deer, and grouse populations.

A straw-like plant ranging from 6-13 feet in height may seem quite harmless to come across. Yet, this plant, known as Phragmites, is an invasive species threatening the natural flora of Michigan.
Phragmites is the most common invasive plant species in Michigan.
Phragmites has a tall stalk with blades along its shaft and a red-colored seedhead that can fade to a straw-like color with age. Phragmites is usually found in wetland habitats like marshes and swamps.
This invasive species poses alarming impacts on biodiversity because it grows tall and in dense stands, squelching out any native plant and animal life by blocking sunlight and taking up space. Animals find it difficult to make habitats because of the density of the stands and find they have reduced vegetation to eat.
Phragmites obstructs views and can make it difficult for people to enjoy nature because of the difficulty of traveling through the thick reeds to get to bodies of water. It also can negatively affect navigation on highways and waterways because of its height. Phragmites has a rapid growth rate and are prone to catching and spreading fires quickly, killing natural vegetation around it and posing threat to homes and buildings nearby.

Two methods of eliminating invasive Phragmites are prescribed burns and the use of herbicides. Prescribed burns are controlled fires that kill the invasive species, allowing a chance for native vegetation to grow. Herbicides must always be used carefully and some areas even require permits before use. Mowing is recommended post-chemical treatment.
Each week, MNA gathers news stories from around the state and country related to conservation and the environment. Here is what happened this week in environmental news:
Piping plovers make comeback in the Great Lakes (Great Lakes Echo): The piping plover, a shorebird once nearly extinct, is on the rebound. There were once only 12 pairs left in the Great Lakes region, but thanks to conservation efforts. scientists are seeing an upswing in the population. The plovers should arrive on the shores of the Great Lakes in the next couple of weeks.
Judges skeptical of challenge to proposed EPA rule on climate change (The New York Times); Lawyers for coal companies, two dozen states, and the Environmental Protection Agency argued before the U.S. Court of Appeals over a rule proposed by President Obama to curb carbon pollution from coal-fired power plants. The rule would require all states to draft plans to restructure their electricity sectors and transition from coal power to cleaner forms of energy. The plaintiffs say the rule is wreaking economic havoc and that the EPA lacks the authority to issue the regulation. They have petitioned the court to block it from finalizing the rule.
New mapping of Great Lakes’ wetlands released (The Swamp School): A new and comprehensive map of the Great Lakes region’s coastal wetlands was recently released by the Michigan Tech Research Institute. The map is the first of its kind, with fluorescent bands of color outlining the Great Lakes. It displays both Canadian and U.S. wetlands along more than 10,000 miles of shoreline. The new coastal map is the result of years of work expanding on previous maps from the Michigan Tech Research Institute.
Endangered Wisconsin Kirtland’s warbler found in the Bahamas (Milwaukee Journal Sentinel): For the first time, scientists have found a Kirtland’s warbler from Wisconsin in the forests of the Bahamas. The bird was one of six warblers banded last summer in central Wisconsin. The state has a total population of fewer than 25 Kirtland’s warblers. It is estimated that there are about 4,000 total Kirtland’s warblers scattered in Wisconsin, Michigan and Ontario. The field crew in the Bahamas has found about two dozen total Kirtland’s warblers since mid-March.

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.

The Red Cedar River Plant Preserve is more than just a 10-acre sanctuary in Williamston, Michigan, and the only one in Ingham County. This sanctuary is one of five MNA sanctuaries within the boundaries of a city and is close to the MNA’s former headquarters.
Usually land within cities has been far too degraded for MNA to claim as a sanctuary, but because of the floodplains within the Red Cedar River Plant Preserve, this area has surprisingly maintained its natural character so close to an urban area. This sanctuary was historically known as the Williamston Floodplain.
The sanctuary consists of floodplains and wetlands because it is so close to the Red Cedar River. There are also marshy and swamp-like areas as well.
These habitats are home to plant-life like marsh marigold, skunk cabbage and jewelweed. Some types of trees that grow on the floodplain ridge are black cherry and red oak. The ridge is welcoming to visitors, giving them a place to walk and explore during spring flooding season.
This sanctuary is one of the few that MNA has built a boardwalk on and it is one of the longest and the only with an observation deck included in its design.
The area was donated in 2005 by Doug and Darlene Price, who with the help of engineer David Geyer have worked on protecting important parts of the habitat. MNA collaborated with them to change the future plans of the development of uplands in order to preserve the area within the sanctuary.
The redevelopment of the sanctuary’s boardwalk will help protect the floodplain. The old design could not withstand the severe flooding so MNA has organized volunteer days to rebuild the boardwalk with a design engineered to allow it to be more stable and provide more access to the sanctuary. About 40 feet of the boardwalk must be built this year of a total of 150 feet, and MNA is enlisting all the help it can get.
MNA extends its gratitude to engineers Jim Rossman and Paul Rice for volunteering their time to develop the design, cost estimates and construction phases, and stewards Jim and Besty Pifer who assisted in the planning process.
Upcoming Volunteer Days:
- Thursday, July 10 at 9 a.m.
