The emerald ash borer is a little shiny green beetle that loves to feast on ash trees. The adult beetles only nibble on the leaves. It's the larvae you've got to watch out for. They munch on the inner bark of the ash tree, and mess with the tree's ability to transport water and nutrients.

The pest has killed tens of millions of ash trees in Michigan alone and tens of millions more in the states and provinces around our region.

Now researchers know a little bit more about how the emerald ash borer ate its way through the state.

State environmental officials have agreed to update air quality permits for two of the state’s biggest and most polluting industrial facilities.

Dearborn’s Marathon oil refinery and Dearborn’s Severstal steel plants have had trouble complying with their state permits in recent years.

The Michigan Department of Environmental Quality now agrees with the companies contention that some of the old standards were too strict. The updated permits relax some emissions rules, while strengthening others.

If you’re a fly fisherman, there are few rivers this side of the Rocky Mountains that compare with Michigan’s Au Sable River. There’s a particular nine-mile stretch east of Grayling known as the Holy Waters.

The water is clean, cold, easy to wade through, and packed with more than 100 pounds of wild trout per acre.

Researchers are uncovering evidence for a timeline for the arrival of an invasive beetle that has destroyed tens of millions of ash trees in the U.S. and Canada.

The emerald ash borer is native to China. Scientists think it arrived in the U.S. via wood packing crates. The beetle eats through the living part of an ash tree underneath the bark and cuts off the tree's water and food supply. This starves the tree to death.

The ash borer continues to spread across the U.S. The researchers found that it may have arrived in North America a decade before it first was detected.

More from the Associated Press:

Michigan State University researchers collected cores from trunks of more than 1,000 ash trees in six southeastern Michigan counties. By studying them, they determined the year each tree was killed by the emerald ash borer and found trees killed as early as 1997.

The ash borer was detected in southeast Michigan in 2002. The researchers say it would take several years before the beetle population was large enough to kill trees, so they concluded it had been in southeast Michigan since at least 1992 or 1993.

The study is published in the journal Diversity and Distributions.

New rules proposed for oil and gas drilling in Michigan are getting a mixed response, at best, from watchdog groups. The rules would apply to a type of drilling often referred to as “fracking.” Critics say the proposed changes continue to favor the oil and gas industry over neighbors and the public.

The official line in Michigan has long been that drilling for oil and gas is well-regulated and done safely. But many people are not convinced.

Hal Fitch is the head of the Office of Oil, Gas and Minerals. He says they are responding to those concerns.

"We saw some need to make some changes, some improvements, partly because of changing technology, partly because of public concern out there over hydraulic fracturing," he says.

The 45-day wolf hunting season that began November 15 inflamed passions, both pro and con.

Now that the first-ever wolf hunt is wrapped up, what were the results?

John Barnes explored the impact of the hunt in a recent piece for MLive, which breaks down the ages of the 22 wolves killed over the course of the hunt. He joined us on Stateside today (you can listen to the audio above).

If you've been wondering why your favorite pine tree has been turning brown as the weather warms up, you can stop wondering and start blaming winter.

Bert Cregg is an associate professor in the horticulture department at Michigan State University. He joined us to explain what the snow, cold and wind has done to our conifer trees.

A snapshot of Pictured Rocks Lakeshore in northern Michigan will be featured on the 2015 National Parks and Federal Recreational Lands Pass. The annual passes are sold nationwide and for use at any national park. Courtney Kotewa of southern Michigan took the photo during a family outing. The image selected as the winning photo of the National Park Foundation's photo contest. 

Nearly 20,000 photos were submitted to the 2013 Share the Experience contest. Share the Experience is the official photo contest of America's national parks and federal recreation lands. 

Kotewa said the photo almost didn’t happen as she was not sure she would take her phone with her on the kayak trip for fear of dropping it in the choppy waters of Lake Superior. Although she grew up in southern Michigan, this trip was Kotewa’s first time to Pictured Rocks. The grand-prize winner said visiting was on her mom’s bucket list.

It’s the 56th year of the study of Isle Royale’s wolves and moose. Researchers at Michigan Tech have just finished this year’s Winter Study.

Rolf Peterson is a research professor at Michigan Tech and he just spent his 44th winter on the island. I called him up to find out how the animals are doing. This year, the team counted nine wolves, up from eight last year.

“I guess I’d say they’re bumping along at the bottom, the bottom of where they’ve been for the last 56 years. So for the last three years, there have been either eight or nine animals total, and that’s as low as we’ve seen them.”

The American Lung Association just released its annual report card on air quality, State of the Air.

Detroit and Grand Rapids made the list of most polluted cities for their ozone levels (Detroit ranks 34th worst out of 220 cities; Grand Rapids ranks 30th).

But others made the cleanest cities list: Kalamazoo and East Lansing scored well for particle pollution. Those are very tiny specks found in smoke and exhaust.

TRAVERSE CITY, Mich. (AP) — Michigan's attorney general and chief environmental regulator have asked the company that owns two oil pipelines stretched beneath an ecologically sensitive area of the Great Lakes for evidence that the 61-year-old lines are properly maintained and in good condition.

Attorney General Bill Schuette and Dan Wyant, director of the state Department of Environmental Quality, posed a lengthy series of questions and requested stacks of documentation in a letter sent Tuesday to Enbridge Inc. and made public Wednesday. They said the pipelines, which run beneath the Straits of Mackinac — the waterway linking Lakes Huron and Michigan — pose a unique safety risk.

"Because of where they are, any failure will have exceptional, indeed catastrophic effects," their letter said. "And because the magnitude of the resulting harm is so great, there is no margin for error. It is imperative we pursue a proactive, comprehensive approach to ensure this risk is minimized, and work together to prevent tragedy before it strikes."

A popular spot in the Indiana Dunes National Lakeshore will remain closed for the summer because of the mysterious appearance of holes in the 126-foot sand dune's surface.

Last July, a six-year-old boy was almost killed when a collapsing hole at Mount Baldy buried him in sand. Since then, two more holes and some depressions have been found.

So far scientists cannot explain why. That's despite the use of ground-penetrating radar and research analysis by scientists from the National Park Service, Indiana University, and the Indiana Geological Survey.

Scientists are getting ready for a more comprehensive investigation of the sand dune this summer.

The Michigan Department of Environmental Quality is proposing changes to their rules for oil and gas drilling in the state.

MDEQ leaders say they've had a successful record regulating the practice of hydraulic fracturing in the state for more than five decades, but new practices by the oil and gas industry are leading to the rule changes.

The industry's practice of horizontal hydraulic fracturing, known commonly as "fracking," has allowed companies to extract a lot more oil and gas from the ground.

Pushing to expand the ban on a lawn care ingredient

Cyanobacteria blooms continue to plague Lake Erie. Farms and wastewater have gotten a lot of attention for contributing nutrients that create these harmful blooms.

More recently, the spotlight has focused on lawn care. Grass fertilizers can also contain phosphorus that winds up in waterways. Michigan and other states around the Great Lakes have already banned lawn fertilizers that contain phosphorus. Now international regulators and others are pushing Ohio and Pennsylvania to do the same.

With the return of warm weather, Consumers Energy has resumed construction of a wind farm in Tuscola County in Michigan's Thumb.  Construction began last October and went on hold during the winter months.

The facility is the company's second wind farm. It will include 62 wind turbines.

Brian Wheeler, spokesperson for Consumers Energy, said the facility should produce enough energy for about 60,000 households.

It's pretty tough to imagine an American city that does not have a coffee shop.

For many places, Starbucks blazed the trail, followed by other chains. And, of course, the hip, locally owned coffee shops.

The variety of flavors and roasts has certainly evolved, from the big brands – the Folgers and the Maxwell Houses – to regionally labeled coffees, and now to beans that are sourced from farms, not just from countries.

So, what's in the future for coffee shops, now that so many of us have discovered we can't do without a really fine cup of coffee?

Lyndon Township

A Ready Mix concrete company wants to dig for sand and gravel on a site north of Chelsea, Michigan. McCoig Materials is planning the mine right in the middle of the Pinckney and Waterloo State Recreation Areas (see the map above for the location of the proposed site).

The plan has drawn opposition from hundreds of residents and other advocates who fear the mine could affect water resources in the area. They also are concerned about the truck traffic that would roll through downtown Chelsea.

Lyndon Township officials will vote on whether the mine should move forward. A meeting has been scheduled next month. From the township:

"How many of you are here to stop the drilling?" one woman asked the crowd of about 200 at a town forum in Scio Township last night.

Big applause broke out.

It was the first indication that the crowd was not going to be a friendly one for the executives from West Bay Exploration, a Traverse City-based drilling company that has asked several landowners in Scio Township to sign over leases for their mineral rights.

The town forum was billed as an opportunity to "become educated about oil and gas leasing."

You’ve probably heard about the big bad invasive silver or bighead carp, also known as Asian carp.

But there’s another invasive fish that’s roughly a third the size of the carp that’s already done a lot of damage to Great Lakes fisheries. Alewives have been a particular menace in Lakes Michigan and Huron. The invasive fish cause all kinds of problems for native lake trout.

Alewives scarf down lake trout eggs and very young fish. But even once lake trout grow big enough to turn the tables and eat the alewives, the invasive fish still cause problems.

It’s been nearly four years since the Enbridge Energy oil spill. Enbridge has already recovered more than a million gallons of heavy tar sands oil from the Kalamazoo River. But federal regulators have ordered the company to clean up another 180,000 gallons that’s mixed in with sediment on the river bottom.

Now that spring is here, work is underway again.

Enbridge spokeswoman Jennifer Smith says dredge work is nearly finished on a section of river near Battle Creek. Workers will remove Ceresco Dam closer to Marshall this summer.

There are fewer wolves living in Michigan’s Upper Peninsula.

State wildlife biologists report a slight dip in the wolf population following last fall’s controversial hunt.

The Department of Natural Resources has just completed a census of wolves in the Upper Peninsula. The DNR admits the count is more of an estimate than an accurate head count.

Children growing up in poverty face huge challenges. One challenge that might not come to the top of the mind, though, is pollution.

As part of Michigan Radio's State of Opportunity project, reporter Lester Graham spent the past three months exploring the problem.

His documentary, "Growing up in Poverty and Pollution," will air tomorrow at 3 p.m. on Michigan Radio.

Lester joined us today to talk about his project.

With its rocky soil, thick forests and painfully short growing season, the Upper Peninsula is never going to look like Iowa or Kansas – and that's okay. For more than a century, a hardy batch of growers and livestock farmers have managed to survive and prosper in these less-than-ideal conditions. Thanks to new technologies and some decidedly low-tech solutions, the U.P.'s latest generation of ag workers are more productive than ever. Ultimately, the fruits of their labor may be felt – and tasted – far beyond the region's borders.

Age-Old Limitations
If you're a U.P. native, you don't need an advanced degree to understand why agriculture is challenging here. But Alger County MSU Extension Director Jim Isleib has one, so people tend to listen to his thoughts on this issue. "Poor soils and a short growing season – that about sums it up," he says.

Today marks the 44th anniversary of Earth Day. Many consider April 22, 1970 to be the birth of the modern environmental movement.

At that time, Earth Day organizers had an advantage: The environmental problems were highly visible, tangible problems that people came up against in their daily lives, such as toxic effluent from factories spilled into streams and rivers. Kids couldn't swim in lakes and rivers because they were too polluted.  Parks and highways were strewn with trash and air pollution made people sick.

You could draw a direct connection between these problems and the need for environmental action to improve the quality of life for everyone.

Many of today's biggest environmental concerns seem more abstract even though they are perhaps even more threatening than the burning river in Cleveland. Global warming is one example.

That's why a study by our next guest caught our eye. He found that what is happening to moths in Finnish Lapland suggests that we're underestimating the impacts of climate change because much of the harm is hidden from view.

Students in northern Michigan are planting clones of ancient sequoias today.

There's a grove of sequoias along the shores of Lake Michigan on the site of a former Morton Salt factory.

Sequoia trees are not native to Michigan, but this grove has grown in Manistee for more than 65 years when they were brought here from the West Coast. Now, those trees are going to take another trip, or their clones will.

Students who attend Interlochen Arts Academy are planting them on campus along Green Lake. The clones are from Archangel Ancient Tree Archive.

David Milarch is the group's co-founder. He says they’re planting clones of redwoods around the world today.

“Ninety-six percent of all of our redwoods have been cut down, butchered and sold,” Milarch says.

Here's a look at how the group collects genetic material from these old growth trees:

Both the Interlochen Center for the Arts and nearby Interlochen State Park have lost many trees recently due to disease and bug infestation.

Head park ranger Chris Stark has mixed feelings about the planting. He'd prefer to plant native varieties, such as the white pine.

I thought I knew a lot about the Great Lakes, until I met Chris Gillcrist. He’s the kind of guy you want on your Trivial Pursuit team.

This is the kind of fact I learned from him every few minutes:

“The first millionaire in American history is John Jacob Astor. It’s a guy trading beaver pelts from the Great Lakes and sending them to Europe.”

Gillcrist is the executive director of the new National Museum of the Great Lakes. It opens this Saturday, April 26, in Toledo.

There are a lot about shipwrecks here, sure,  but Gillcrist wants you to know it’s much more than that.

“We look at it as retrofitting American history to more accurately depict how the Great Lakes impacted the nation as a whole over the past 300 years,” he says.
