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).
