‘Human-toothed’ Pacu in Michigan waters, endangered species running out of time (Great Lakes Echo): The Michigan Department of Natural Resources recently reported finding fish with “human-like teeth” in southeastern Michigan lakes. Anglers spotted red-bellied pacu in Lake St. Clair and near Port Huron. These unusual fish sport teeth eerily reminiscent of humans’ so they can eat seeds and nuts. While they’re not native to Michigan, DNR said they’re not invasive.

Celebrating 100th anniversary of parks system with a great Great Lakes view (Great Lakes Echo): The U.S. National Park Service celebrates its centennial in 2016, commemorating 100 years of stewardship of America’s natural and historic treasures. Many of those monuments, scenic rivers, parks, and historic sites are visible from space – where the views are just as compelling.

Endangered butterflies released by Kalamazoo Nature Center (WMUK 102.1): The Kalamazoo Nature Center released 18 rare butterfly caterpillars. The Mitchell’s Satyr butterfly is a nationally endangered species. There are only 11 groups of the butterfly left in the entire United States. The Mitchell’s Satyr has been called a “canary in a coal mine” for America’s wetlands. Almost all of the butterflies live in the southernmost counties of Michigan because they live in a rare habitat – fens.

Loony for a diving bird (Great Lakes Echo): Great Lakes common loons are a barometer for water and habitat quality since they’re sensitive to pollution and very particular about where to nest. Listen to the podcast to learn more about the common loon.

Forest Birds, Fish Slides, and Rare Butterflies: this week in environmental news

Great Lakes forest birds mostly stable or increasing (Great Lakes Echo): A record study that took 25 years and 700 birdwatchers and researchers has found that most birds at three different national forests in the Great Lakes region are either increasing or stable. The study is another great example of the important role volunteer bird watchers can play in tracking populations of the birds they love. The count became an annual tradition for many bird enthusiasts. The study is cause for guarded optimism about the state of forest birds in the Northwestern Great Lakes Basin.

Fish slides, anyone? (Great Lakes Echo): Sturgeon go back to the river to spawn safely. But hydroelectric dams often block rivers, forcing fish to spawn in more dangerous spaces. Listen to this podcast to learn more about how the River Alliance of Wisconsin is giving fish a little boost.

Healthy ravines for healthy watersheds (Great Lakes Echo): Created by the same retreating glaciers that carved and filled the Great Lakes, you could say lakeshore ravines are the lakes’ blood relatives. Great lakes ravines face deterioration at the hands of invasive species and pollution. Conservationists are working to address this issue.

Rare butterfly rests its wings in unique SE Michigan ecosystem (Great Lakes Echo): Listen to WKAR’s radio story about Kevin Lavery’s expedition to find the endangered Poweshiek Skipperling. It’s only found in a half a dozen places on Earth, and two-thirds of them are in Michigan. The rare butterfly once thrived on the Great Plains is now fighting for its survival in Michigan.

MI Invasive Species, Poweshiek Skipperlings, and Bees: this week in environmental news

Michigan Invasive Species (MI.gov): Does your work take you to several outdoor sites in one day? Do you fish or hunt at different locations in the same week? If so, your actions could be considered high-risk for spreading species around the state. Want to learn more? Take a few minutes to watch this new video that briefly explains the best ways to look for and remove invasive species.

The Poweshiek Skipperling: A Prairie Butterfly on the Brink (U.S. Fish & Wildlife Service Endangered Species): Poweshiek skipperlings are small butterflies that live only in native prairies that have never been plowed, which makes them vulnerable. Until recently, the species (Oarisma poweshiek) was one of the most common prairie-obligate skipper in the Midwest. Yet, in the last decade, surveyors observed an abrupt and rapid decline in the species, and population after population began to vanish. Despite extensive surveys, the skipperling appears to exist in critically low numbers at just a handful of sites scattered between Wisconsin, Michigan, and Manitoba.

Trail segment installed at Sleeping Bear (Great Lakes Echo): A ribbon-cutting ceremony was held recently for a new segment of the Sleeping Bear Heritage Trail at the Sleeping Bear Dunes National Lakeshore. The trail will eventually run 27 miles from Empire northeast about halfway up the Leelanau Peninsula. To limit environmental impact, the trail follows existing utility corridors, abandoned roads and a narrow gauge railroad. That minimizes its impact on forested areas and wetlands. Boardwalks are built with helical piles, a more environmentally friendly alternative to cement foundations. Instead of digging up landscape and pouring permanent cement, the piles screw directly into the ground and can be unscrewed if needed.

MSU researcher: more wild bee habitat would benefit growers (Great Lakes Echo): For farmers across Michigan and the country, pollination is essential for making their crops grow. For years now, they’ve kept a close eye on a key pollinator, bees, mainly because their numbers have been declining. Listen to the podcast with Rufus Isaacs, a professor of entomology at MSU, to learn more.

Great Lakes, Robot Cleanup, and Cormorants: this week in environmental news

Water levels and surface temperatures up for Lakes Michigan/Huron in 2016 (MSU Extension): Visitors to the beaches and boat launch ramps will notice both higher lake levels and earlier seasonal warming of the Great Lakes than in the past several years. The NOAA Great Lakes Environmental Research Laboratory shows that Lakes Michigan and Huron are the highest they have been since August 1998. What about the water temperatures? Again, they are well ahead of 2015 and well ahead of long-term average of Lake Michigan.

Robot is on a mission to clean up Great Lakes shorelines (Great Lakes Echo): A robot designed by a maker in Toronto could soon be clearing up trash strewn across shorelines everywhere. The next step involves many more field tests throughout the summer and small revisions to the robot’s design. After those tests are complete, the robot will be deployed in August on Toronto Island in Lake Ontario to clean up the shoreline. There’s a lot of interest in the project because it combines robotics with environmentalism, creating a robot with a social impact.

The dirty eight: Great Lakes pollutants targeted by U.S. and Canada (Great Lakes Echo): Canada and the U.S. recently announced they will develop and coordinate strategies to reduce exposure to eight contaminants they have designated as Chemicals of Mutual Concern in the Great Lakes. The designation made under the Great Lakes Water Quality Agreement also requires the countries to develop where needed the water quality standards for the pollutants.

Cormorants

Can cormorants help control Great Lakes invaders? (Great Lakes Echo): Cormorants’ fish-stealing rep may be a bum rap – and the truth is more complex, as the first dietary study of cormorants in southern Lake Michigan shows. Researchers found the cormorants are chowing down on invasive species – mainly alewife, round goby and white perch – which together accounted for 80-90% of their diet. No studies to date have demonstrated that cormorants have a consistently negative effect on fisheries over broad geographic regions.
