If you eat wild caught fish from Michigan, you might know about fish consumption advisories. They’re recommended limits on safe amounts of fish to eat, and they're necessary because toxic chemicals build up in fish in the Great Lakes and inland lakes and streams.

Native plants are better for birds than non-native plants.

That’s the main finding of a study on chickadees and the caterpillars they eat.

People in northern Kent County have been dealing with the recent discovery of groundwater contamination for the past several months.

Some residents still have questions about what caused it and how it could affect their health.

We’ve heard a lot about honeybees and how important they are as pollinators. But bumblebees pollinate wildflowers and crops, too, and some kinds of bumblebees are in trouble.

One of the things Flint’s water operators got in trouble for was falsifying records; for saying the city was testing homes at the highest risk of having elevated lead levels when it was not. But records obtained by Michigan Radio show Flint is not the only city in the state that tested the wrong homes over the years and potentially underestimated lead in water.

The biggest culprit for high lead in tap water is the lead water pipes that connect a house to the water main. That’s why cities are supposed to test those homes.

The reliability of our power supply is vulnerable to climate change. But the grid can be made more adaptable.

Those are the conclusions of a new study in the journal Nature Climate Change.

For generations, Native Americans in the northern Great Lakes have harvested wild rice. It's an important food source. For some it's a way to make a little extra cash. And it's a cultural touchstone that tribal members are trying to pass on to younger generations.

Lakes Superior and Erie have too many sea lampreys.

The invasive fish latch onto big fish like lake trout and salmon and drink their blood and body fluids. A single lamprey can kill up to 40 pounds of fish in its lifetime.

If you hit the grocery stores in the Toledo area a couple weeks ago, hoping to pick up some bottled water, you were out of luck.

Several stores completely sold out, thanks to rumors that the city would soon be issuing another “do not drink” advisory for tap water. It didn’t.

But water pollution in the Maumee River and western Lake Erie is creating harmful blooms so large, you can literally see them from space.

Canada geese have been spending their winters farther north.

Scientists have figured out geese are drawn to cities for safety more so than for food.

Michael Ward is an associate professor in the Department of Natural Resources and Environmental Sciences at the University of Illinois at Urbana-Champaign. He’s an author of a study on Canada geese in the Chicago region.

Ward and his team fitted Canada geese with radio collars and tracked them for two years, trying to understand why there are so many geese in Chicago during the winter.

“And what we learned was that they weren’t going there for food, they were going there because there were no hunters,” he explains. “So all of the Canada geese that spent the winter in Chicago survived, whereas half of the birds that decided to leave the Chicagoland area and go to areas where hunting is allowed and more prevalent were harvested.”

Ward says geese are all about conserving energy.

Lake Superior is cold, deep and clear. But it’s no longer the clearest of the Great Lakes.

Lakes Michigan and Huron have gotten clearer, bumping Lake Superior to number three.

Scientists have been able to figure how much clearer by using satellite imagery.

Researchers find there could be more health effects lingering decades after a toxic contamination of Michigan’s food supply.

Well... it's not an absolute "no."

It's more of a "probably not," given what we've learned about the Huron Mountain Club in reporting this story.

We'll get to the downright practical ways you might get into the club below. In the meantime, we'll just say it doesn't hurt your chances if you’re Channing Tatum, or related to Henry Ford (and even Ford had trouble getting in).

Most veterinarians probably don't picture themselves working with bees. But thanks to new federal regulations, more and more might soon find themselves with six-legged patients.

There’s a new guy running the drinking water division at the Michigan Department of Environmental Quality.

Eric Oswald served 12 years of active duty in the Air Force. He spent the last five years as a commander at the Air National Guard Base in Battle Creek.

Oswald is not a drinking water expert.

Antidepressants that people take are building up in the brains of fish like walleye, bass, and perch. Researchers studied fish from the Niagara River, which connects lakes Erie and Ontario.

Solving a sugar maple mystery

Sep 6, 2017

Earthworms seem pretty harmless. But they’re causing problems for Michigan’s multi-million dollar sugar maple industry.

That’s the finding of a study by Tara Bal, a research assistant professor of forest resources and environmental science at Michigan Technological University.

Listen to today's Environment Report.

Around the Great Lakes, millions of dollars are spent to fight invasive species like Asian carp. But when scientists find a new animal or plant in the area, it’s not always clear if it’s harmful or helpful.

Common carp have been in Michigan since the late 1800s. They’re not considered an invasive species because they’ve been around so long. Many people consider them to be a “trash fish,” but flyfishing for carp is very popular in northern Michigan.

There’s a green bloom of cyanobacteria on Lake Erie again. People who run water utilities and scientists are watching the bloom because the cyanobacteria can produce toxins called microcystins that are dangerous for people and pets. It's what made Toledo’s drinking water unsafe to drink in 2014.

Chris Winslow directs Ohio Sea Grant and Ohio State University’s Stone Laboratory. He says the bloom’s covering about 10% of the western basin.

Building a better Lyme disease test?

Aug 17, 2017

Experts tell us it’s important to treat Lyme disease early, and state officials say Lyme disease is the most common tick-borne disease in Michigan. 

But officials with the Centers for Disease Control and Prevention say it can sometimes be confused with a similar condition that’s also transmitted by ticks, called Southern Tick-Associated Rash Illness, or STARI.

One of the toughest things about being a parent in Flint right now is the uncertainty. If your kid gets diagnosed with ADHD, or struggles in school, there’s a part of you that wonders: is it because of the lead exposure?  

An Asian carp was caught this summer in a place where it shouldn’t be – beyond an electric barrier meant to keep the species out of Lake Michigan and the rest of the Great Lakes. Now, a researcher at Southern Illinois University is trying to figure out just how it got there.

Trying to trap invasive sea lamprey with "eel ladders"

Aug 9, 2017

The sea lamprey is an invasive fish with a round mouth like a suction cup. It latches onto big fish like lake trout and salmon, drills its razor sharp tongue into them, and gets fat drinking their blood and body fluids. A single lamprey can kill up to 40 pounds of fish in its lifetime.

We spend about $20 million dollars a year to control lampreys. One of the main ways people do that is with a pesticide, but researchers are working on other ways to control the invasive species.

Water filters that you attach to your faucet are known to be good for filtering out heavy metals like lead and disinfectants like chlorine. But they’re not designed to filter out bacteria that can grow in the filter itself.
