August is Tree Check Month (Statewide DNR News): The U.S Department of Agriculture has declared August as national Tree Check Month – time to be on the lookout for invasive, destructive pests threatening Michigan’s urban and forest landscapes. Take 10 minutes this month to check trees around homes for Asian longhorned beetle or any signs of the damage it causes. Like the emerald ash borer, the Asian longhorned beetle spends most of its life cycle eating its way through the insides of trees. What makes this beetle much more dangerous is that it feeds on a wide variety of tree species. Its first choice is maple, but it also will infest birch, elm, willow, buckeye, horse chestnut and other hardwoods. Trees infested with Asian longhorned beetle must be destroyed to prevent the insect from spreading.

DNR calls on citizen scientists to report cougars, feral hogs, and other wildlife with new app (Michigan Radio): The Department of Natural Resources invites Michigan residents to contribute to conservation efforts by reporting their fish and wildlife observations with the new Eyes in the Field application. Available at michigan.gov/eyesinthefield, the application replaces 15 separate observation forms the DNR had been using to gather important information about the state’s fish and wildlife populations. Eyes in the Field includes forms for reporting observations of diseased wildlife, tagged fish, mammals such as cougars and feral swine, fish such as sturgeon, birds such as wild turkeys, and reptiles and amphibians such as eastern massasauga rattlesnakes. Additional observation forms will be added in the future.

Trees are aware of their neighbors and give them room (Treehugger): In ‘crown shyness,’ some tree species respect those nearby and keep their leaves to themselves. The phenomenon has been studied since the 1920s, and is also known as canopy disengagement, canopy shyness, or intercrown spacing. It doesn’t happen in all tree species; some species that do it only do it with trees from the same species – some species do it with their own as well as other species.

New video gives tips on identifying red swamp crayfish (Statewide DNR News): Though they are native to southern states, red swamp crayfish are considered invasive in Michigan because they compete aggressively with native crayfish species for food and habitat. They feed on plants, insects, snails, juvenile fish and other crayfish, disrupting the food chain for many aquatic species. The Michigan Department of Environmental Quality has created a new video to help people identify and report red swamp crayfish. The video is the third in the department’s MDEQ Minute series, offering 60-second views on a broad range of topics including new and potential invasive species in Michigan.

Monarchs, American Wetlands Month, and Migratory Bird Festival: this week in environmental news

Monarch butterflies winging their way north to Michigan (MDNR): With spring now sprung in Michigan, soon we’ll be welcoming back to the state one of the most distinctive signs that summer is on its way – the brightly colored monarch butterfly. Monarchs are on their way north from Mexico, where they spend the winter months. While National Start Seeing Monarchs Day is observed annually on the first Saturday in May, it may be a few more weeks before they make their way across Michigan. One of the most well-known and beloved butterfly species in North America, with their easily recognized orange and black wing pattern, monarchs have become a much less common sight in recent decades. The eastern monarch butterfly population has declined by 90 percent over the last 20 years due mainly to habitat loss, both in their summer range – including Michigan – and in Mexico, where they overwinter. The alarming declines in monarchs and other pollinators have sparked conservation programs across the nation. There are many ways that Michigan residents can contribute to ongoing monarch conservation efforts as well. Creating habitat for monarchs and other pollinators, whether it’s in your backyard or a large field, is a great place to start. Other resources include the Create Habitat for Monarchs web page from Monarch Joint Venture and “How to build a butterfly and pollinator garden in seven steps” from the U.S. Fish and Wildlife Service. Another way you can contribute to monarch butterfly conservation efforts is to monitor monarch populations by reporting any sightings at Journey North or getting involved in other monarch citizen science opportunities.

Celebrate American Wetlands Month by exploring Michigan’s wetlands (TV6): May is American Wetlands Month – a month to appreciate and enjoy the wonders of wetlands. The Department of Natural Resources encourages Michigan residents to get out and enjoy some of the outstanding wetlands the state has to offer. Try visiting one of Michigan’s Wetland Wonders for a day of hiking, birding, kayaking or fishing.

The Keweenaw’s Migratory Bird Festival (Copper Harbor Birding): Join the Copper Harbor Birding group in celebrating the spring bird migration by offering a season full of bird and other nature related activities. The birds are the main focus, so get out there! Guided bird and nature walks are offered throughout the season.

Making your native plant choices for Michigan inland lake shorelines (MSU Extension): Michigan’s inland lakes draw many people for a variety of reasons. Being close to nature and being a part of a relaxing natural environment are not the least among them. However, the reality of owning a lake home often is at odds with what nature provides. When choosing native plants for your shoreline you should have a landscape design plan and know the Lake fetch or prevailing wind direction on your lake in relationship to your property. Then go about choosing what plants will serve your needs and aesthetic. The important thing to remember is to choose the right plant for the right place.

Small snail, big problems: Researchers track invasive New Zealand mudsnail in Michigan rivers (MDNR): A tiny invader is threatening prized trout streams in Michigan’s northern Lower Peninsula.  A mere 1/8-inch long, the New Zealand mudsnail is barely distinguishable from a grain of sand, but over time its invasive habits can affect the quality and quantity of trout and other fish in the Au Sable, Pere Marquette and Boardman rivers where it has been found. The Department of Environmental Quality recently released a new video providing an overview of New Zealand mudsnail identification. The video is the premiere in the “MDEQ Minute” series, offering 60-second views on a broad range of topics including new and potential invasive species in Michigan. If you think you have found a New Zealand mudsnail in a waterway outside of the Pere Marquette, Boardman or Au Sable rivers, report your finding using the Midwest Invasive Species Information Network website, www.misin.msu.edu, or download the MISIN app to your smartphone.

Birding Trails, Fungi, and Protecting Native Species: this week in environmental news

Birdwatchers celebrate two new birding trails in Michigan (Great Lakes Echo): Michigan’s Northwest Lower Peninsula is a paradise for birdwatchers. Piping plovers, on the endangered species list, and the snowy owl nest there in the winter. The region is a stopover for thousands of birds on their way to breeding grounds. The Petoskey Regional Audubon Society, in partnership with local conservancies, plans to celebrate the launch of the Sunset Coast Birding Trail later this year. The trail will start in Mackinaw City and follow a coastal corridor through Emmet, Charlevoix and Antrim counties. According to a report of the Mackinac Straits Raptor Watch, a nonprofit organization that educates the public about the birds and their migration, 47,090 birds migrated through the straits in 2016. Another new trail, The Blue Water Birding Trail in St. Clair County, is also expected to launch this year. Michigan has six birding trails already – North Huron Birding Trail and Superior Birding Trail in the Upper Peninsula, and Sleeping Bear Birding Trail, Beaver Island Birding Trail, Sunrise Coast Birding Trail and Saginaw Bay Birding Trail in the Lower Peninsula.

Fantastic Fungi in Michigan (Oakland County Times): “Fantastic Fungi in Michigan: You don’t have to go to the rain forest to see amazing mushrooms” speaker program is being held on Wednesday, April 12th, 2017 beginning 7:30 pm at the Royal Oak Middle School (709 N. Washington). Join Mary Fredricks, Nature Society mycologist, and learn about mushrooms tiny enough to grow on oak leaves, beautiful mushrooms that are among the most poisonous known, mushrooms that are easy to overlook during the day but glow at night, and more, all growing right here in Michigan. There is no preregistration or cost for this program.

Usually the villain, invasive species odd hero for native fish (Great Lakes Echo): A native fish may be poised for a comeback in the Great Lakes with the help of an invasive species. Great Lakes cisco, also known as lake herring, typically grow about 12 to 15 inches long and at one point supported one of the largest commercial fisheries in the region. They disappeared from much of the basin around the 1950s. Now it looks like the stage has been set for their return–by an unlikely ally. Invasive quagga mussels have depleted nutrients in the lakes. Cisco do well in low-nutrient environments, unlike competing species like the invasive alewife. That gives cisco space to thrive.

Trump admin delays listing bumblebee as endangered (The Detroit News): The Trump administration delayed what would be the first endangered designation for a bee species in the continental U.S., one day before it was to take effect. The U.S. Fish and Wildlife Service adopted a rule Jan. 11 extending federal protection to the rusty patched bumblebee, one of many types of bees that play a vital role in pollinating crops and wild plants. It once was common across the East Coast and much of the Midwest, but its numbers have plummeted since the late 1990s.

 

Bee Restoration, Lake Trout, and Birding Apps: this week in environmental news

To save bees, city plans 1,000 acres of prairie (mother nature network): It’s generally a bad time to be a bee in the United States. Populations of the pollinating insects have been declining for more than a decade, including managed honeybee colonies as well as various species of native wild bees. Of course, this isn’t just bad news for bees. Not only do honeybees give us honey and wax, but bees of all stripes play a pivotal role in our food supply. This spring, the city of Cedar Rapids will seed 188 acres with native prairie grasses and wildflowers, part of a broader plan to create a diffuse, 1,000-acre haven for bees and other pollinators. This should help local ecosystems as well as local farms, and if it works as intended, it could become a model for similar projects elsewhere. The 1,000 Acre Pollinator Initiative in Cedar Rapids is hoping to create a movement to build oases for pollinators across the country.

Searching for bee veterinarians (Great Lakes Echo): Michigan State University is searching for veterinarians willing to treat bees. The Pollinator Initiative at Michigan State launched the search after a recent FDA decision outlawed over-the-counter antibiotics for all food-producing animals. That means a veterinarian has to give beekeepers a prescription for antibiotics. Meghan Milbrath, a beekeeper of 23 years, has a list of 22 Michigan veterinarians who are willing to work with beekeepers, and it is online for beekeepers to find and pick from, depending on their location. In the meantime, Milbrath will train the veterinarians on how to write bee prescriptions. She is teaching online courses and hosting monthly webinars. Eventually, she hopes to create a bee health elective in the College of Veterinary Medicine at MSU.

Unique lake trout could help restore Lake Michigan population (Great Lakes Echo): Scientists have found a potential new ally in the fight to restore lake trout in Lake Michigan. Elk Lake in Northwest Michigan is home to a strain of that fish that researchers believe can contribute uniquely to restoring it. Elk Lake trout have been self-sustaining and reproducing for years. Scientists have been attempting for decades to reintroduce strains from Lake Superior and other areas in the basin–with mixed success. Stocking from Elk Lake may be more successful. Diversity benefits reintroduction efforts because different strains survive in different habitats. Improving lake trout stocking has broad public support.

It’s like Shazam for birds: Song Sleuth app IDs birds by their song (treehugger): The Song Sleuth app was just released for iOS, with an Android version in the works for this fall, and it not only helps people become better birders by helping them identify birds by their songs, but it also includes access to The David Sibley Bird Reference, which offers additional details about the birds, including the birds’ seasonal range maps, song samples, and illustrations of their appearance. Song Sleuth users need merely open the app, push the record button, and allow the app to listen in and record the bird’s song, after which the users are presented with the three most probable birds that the song belongs to. Users can geotag their recordings, add custom notes to them, download the audio files for future reference, or even send their recordings to others via email of messaging apps, further adding to the social nature of the birding community (or used to attract more people to the art and science of birding).

Michigan Lake and Stream Leaders Institute, Frogs, and Endangered Bumblebees: this week in environmental news

Michigan Lake and Stream Leaders Institute (MSU Extension): The Michigan Lake and Stream Leaders Institute (LSLI) provides a unique and intensive leadership development opportunity for citizens, local leaders, and water resource professionals who wish to develop technical and people skills needed by leaders who can effectively protect Michigan’s lakes and streams. Participants take part in classroom and field-based sessions designed to help them better understand local water resource management planning and program implementation. Expert presenters from academia, natural resource agencies, and local communities cover topics including watershed management, lake and stream ecology, environmental education, leadership, and working with local and state government. The Institute is conducted through five in-depth sessions held across Michigan. The sessions will be held:

  • June 2-3: Kettunen Center, near Cadillac
  • August 18-19: Kellogg Biological Station, near Kalamazoo
  • October 6: Michigan State University, East Lansing

Supernatural spit is the frog’s secret weapon for catching bugs (Mother Nature Network): Frogs are famous for the long sticky tongue they use to snag prey. But what is it about this tongue that allows a frog to nab an insect, pull the insect back to its mouth with lightening speed, and eat it — yet the stickiness doesn’t glue the frog’s mouth shut? The secret is super sticky saliva that’s reversible. A new study demonstrates that the saliva can turn from a honey-like viscosity to one more like water and back again, and all within a few seconds. Super-special spit and a trippy tongue make capturing insects a snap.

National Park Service starts keeping track of park disturbances (Great Lakes Echo): For the first time, the National Park Service is collecting concrete data to monitor and find patterns in what affects national park landscapes. The data on how park landscapes are affected by various disturbances both inside and outside the parks will help park managers maintain them for the ecosystem and for the visitors. Fire and beavers, for example, play key roles in developing habitat by changing the structure or composition of the landscape. Similarly, some human-induced disturbances are better for the environment than others. Sustainable forest harvest can aid the regeneration of a forest, while land development for things like new parking lots do not. Cataloging the disturbances will help with assessing if the impact is beneficial or recoverable.

Fight invasives or protect pollinators: Neonicotinoids present tough choice (Great Lakes Echo): Neonicotinoids, a class of insecticides frequently used in agriculture, gets plenty of bad press for killing pollinators like honeybees. But they’ve also emerged as an important combatant of the emerald ash borer, an invasive insect that has devastated ash populations all over the United States with the highest risk localized to the American Midwest and the northern half of the Eastern seaboard. For pollinator protectors in Michigan, that’s a problem. With the recent designation of the rusty patched bumble bee as endangered by the U.S. Fish and Wildlife Service – the first time any bee species in the U.S. has landed on such a list – the race for effective conservation tactics has accelerated. The Michigan Pollinator Protection Plan Committee will have a draft of the plan available for public comment between March 10 and April 14.

Lake Erie Waves, Great Lakes Forests, and Mudpuppies: this week in environmental news

This Is What A Great Lake Looks Like After All The Vacationers Are Gone (Buzzfeed): Photographer Dave Sanford spent time on Lake Erie shooting the Great Lake’s turbulent fall season. From mid-October to mid-November, the longtime professional sports photographer traveled each week to Port Stanley, Ontario, on the edge of Lake Erie to spend hours taking photos. His goal was to capture the exact moment when lake waves driven by gusting winds collide with a rebound wave that’s created when the water hits a pier and collection of boulders on the shore. People are blown away that these are from a lake, and not an ocean due to the size and force.

Pharmaceutical pollution takes toll on crayfish and other species (Great Lakes Echo): Drugs seeping into groundwater threaten crayfish and have a domino effect of environmental impacts that harm fish and other species, according to new research. Pharmaceutical pollution happens when medicines are improperly disposed or flushed into septic tanks and sewers as the body eliminates them. Treatment can’t filter them so they make their way into lakes and streams. Crayfish are a keystone species, one that many others species depend upon. If they died, so would trout and bass. That would lead to algae overgrowth and in turn, insects and invertebrates would die when decaying algae used up all the oxygen. At this point there are not solutions for removing pharmaceuticals once they are in lakes and streams, so this is a prevention issue. We need to keep it out of the waterways, improving septic and sewer systems to filter pharmaceutical pollution is a critical need.

Researchers look to brace Great Lakes forests for climate change (Great Lakes Echo): Great Lakes forests will get warmer and suffer more frequent short-term droughts, scientists say. The stakes are high. Forests are staple ecosystems in the region. Many wildlife and plant species depend on forest stability. Plus, forests are a part of the regional culture. The approaches to climate change adaptation for trees are as diverse as the tree species.

Secretive amphibian can provide pollution clues (Great Lakes Echo): The mudpuppy is a fully-aquatic salamander thought to be on the decline–though the extent of that decline is unknown. The foot-long amphibians are classified a “threatened species” in the state of Illinois and considered a concern throughout the Great Lakes region. Destruction and degradation of habitat, along with invasive species, are spelling doom for mudpuppies. Mudpuppies are also very sensitive to pollution. That characteristic could make them especially important to researchers. Population statistics and tissue samples could clue scientists in on the effects pollution and habitat degradation are having on those environments.

Native Prairies, Mini-Tsunamis, and Sand Dunes: this week in environmental news

Native prairie restoration fights invasive species and helps the endangered ones (Great Lakes Echo): From flower pots to 100-acre lots, planting native prairie plants is increasingly important as they face threats from invasive species and human development. Prairies in the Great Lakes region are known for hosting bobolinks, wild turkeys, butterflies and a vast array of wildflowers. A program was created to collect seeds from native plants to promote prairie growth and engage volunteers with the environment. It’s something that everyone can help with.

Researchers creating warning system for low oxygen water (Great Lakes Echo): Researchers are developing a system to warn water managers when unpalatable, harmful water from Lake Erie is headed their way. The project, with $1.5 million in federal funding, could give water treatment plant operators time to prepare to treat water that is hypoxic by predicting the movement of oxygen-depleted Lake Erie water. Hypoxia occurs when dissolved oxygen in a body of water is depleted to a level that is harmful to aquatic organisms. This is a particular problem in the central basin of Lake Erie, where it’s deeper.

Mini-tsunamis a hazard in the Great Lakes (Great Lakes Echo): The Great Lakes have their own miniature version of tsunamis – more than 100 times per year. That’s according to new research led by the University of Wisconsin Madison. The name of these waves – and the danger that comes with them – are relatively unknown to those in the region. Their name, meteotsunami, is a contraction – broken down, it means meteorological tsunami. They’re about a foot high. And they’re not caused by earthquakes like actual tsunamis. Researchers are now looking into a way to predict when these mini-tsunamis might occur in order to warn beachgoers. According to the study, Lake Michigan is most prone to these mini-tsunamis, followed by Lake Erie and Lake Huron.

Michigan Dune Alliance helps protect Michigan’s iconic sand dunes from invasive species (Model D): From the towering glory of Sleeping Bear Dunes to more modest southern Lake Michigan beaches, perhaps nothing in our state represents “Pure Michigan” better than our iconic sand dunes. But as with so many of Michigan’s fragile native ecosystems, invasive weeds threaten to strangle the dunes. Exotic fungi and invasive bugs are killing the trees that are part of the dune ecosystem, while invasive water plants are choking coastal marshes and interdunal wetlands. There are around 550 miles of coastline on the Mitten’s west that are under siege from alien invaders. Luckily, the combined forces of the Michigan Dune Alliance are on a search-and-destroy mission throughout that long stretch of sand.
