invasive species

Lester Graham / Michigan Radio

More than 130 scientists and the state’s environmental groups are calling on Gov. Rick Snyder to veto a bill they call anti-science. The bill would forbid the Michigan Department of Natural Resources from protecting native wildlife and plants on the pure merits of protecting nature.

  • The bill would prohibit the Department of Natural Resources from managing state lands for biodiversity.
  • It would prohibit the agency from managing forests for restoration.
  • It would end work to eliminate invasive species.
  • It would strike from the law the finding that most losses of biological diversity are the result of human activity.

State officials recently updated the list of invasive species banned in Michigan. They added seven species to the list. That means you can’t have them in your possession or move them around.

More than 2,500 species of plants, fish and mollusks will be invading the internet soon.

It’s an effort by more than 20 museums and universities around the Great Lakes region (including the University of Michigan, Michigan State University and Central Michigan University). They’re teaming up to digitize their collections of species that are not native to the Great Lakes.

Ken Cameron directs the Wisconsin State Herbarium at the University of Wisconsin-Madison, and he’s leading the project. He and his collaborators will be pulling fish and mollusks out of jars and taking dried plants out of drawers, taking photos of them, and uploading them to the online collection along with data about the species. He and his colleagues around the region will be doing this for 1.73 million specimens.

The U.S. Army Corps of Engineers is figuring out new ways to try to block two species of Asian carp — bighead and silver — from getting into Lake Michigan. The Corps also wants to block other aquatic nonnative species from getting into the Lakes from the Mississippi River system.

They’re considering whether to put in new barriers near the Brandon Road Lock and Dam in the Des Plaines River near Chicago. The site is about five miles downstream from a system of electric barriers in the Chicago Ship and Sanitary Canal. Those barriers are essentially the last line of defense against Asian carp in the Chicago area.

“This may be a perfect site to implement a range of different kinds of technologies," says Dave Wethington, a project manager with the Army Corps in Chicago.

He says the Corps could put in barriers that block fish passage into the lock and dam, or more electric barriers. It could also put in special water guns that use pressure waves to deter carp.

ALLEGAN, Mich. - Officials say genetic material of Asian carp has been found in a river in the Kalamazoo River in southwestern Michigan.

The state Department of Natural Resources and the U.S. Fish and Wildlife Service on Tuesday announced DNA from silver carp was detected in one of 200 samples taken in July the Kalamazoo River in Allegan County. The river flows into Lake Michigan.

Officials say the discovery marks the first time so-called environmental DNA for silver carp has been found in Michigan's Great Lakes waters outside of Maumee Bay in Lake Erie. In a statement, the agencies say there's "no evidence that a population of silver carp is established."

The silver carp is one of the Asian species threatening to invade the Great Lakes and compete with native fish for food.

The bass are getting fat.

Lake Michigan was recently recognized as one of the best places in America to fish for bass. The booming fishery is one sign of what might be a major shift of the lake’s food web.

But that change is being driven by an increase in goby, an invasive species. And it could spell trouble for salmon— the most popular sport fish in Lake Michigan.

Would you:

A) run away screaming

B) attack them with golf clubs, weed whackers and curling irons, or

C) haplessly fall victim to them as you enjoy a quiet afternoon of fishing with your dog?

The residents of a fictional Michigan town do all of the above in "Blood Lake: Attack of the Killer Lampreys" airing this week on Animal Planet. It's by the same people who brought us "Sharknado."

Watch the trailer below:

Really, it was only a matter of time. With its toothy suction cup for a face and razor sharp tongue, the sea lamprey was a horror movie villain just waiting to shine.

Asian Carp

When you hear the words "Asian carp," chances are that nothing good will come to mind.

We know they're big, ugly, lightning-fast, voracious eaters, and a highly invasive species. 

And there are great fears as to what could happen if they decide to make the Great Lakes home. 

Duane Chapman is a research fish biologist for the U.S. Geological Survey. He leads their Asian carp research. Chapman is among scientists who say there has been an up side to all the studies they've been doing since the Asian carp came onto our radar screens. 

He joined today us on Stateside.

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.

TRAVERSE CITY – A group of U.S. senators wants the federal government to move faster on preventing Asian carp from reaching the Great Lakes through waterways in the Chicago area.

Eleven senators from states in the region sent a letter Tuesday to the assistant secretary of the Army, whose office oversees the Army Corps of Engineers. The letter asks a series of questions about when the Corps might begin tasks such as adding barriers at the southernmost lock in the Chicago Area Waterway System.

It also asks what authorization the Corps needs from Congress to move more quickly toward short- and long-term solutions.

The Corps issued a report in January with options for blocking the invasive carp's path to Lake Michigan, but says Congress and regional stakeholders must choose the final plan.

About a hundred people showed up at a public hearing Tuesday night in Ann Arbor to discuss ways to keep Asian carp from getting into the Great Lakes.

One by one, people took to the microphone to tell the U.S. Army Corps of Engineers the only way to stop the Asian carp is to close the man-made waterways connecting the Great Lakes to the Mississippi River basin.

Asian carp have devastated native fish populations in parts of the Mississippi River basin since first being introduced in the southern United States. Some species of Asian carp were brought in to help keep retention ponds clean in aquaculture and wastewater treatment facilities.

This week federal officials will talk about the options for preventing Asian carp from reaching Lake Michigan.

People and organizations will get a chance to have their say about which option they support. The U.S. Army Corps of Engineers will host meetings in Ann Arbor on Tuesday night and in Traverse City on Thursday.

The meetings are two of six scheduled this month, from Louisiana to Pennsylvania. Officials will also take written comments through early March.

This week, the U.S. Army Corps of Engineers issued a study about what might be done to keep those invasive Asian carp out of the Great Lakes.

It took seven years and that was a rush job after some members of Congress accused the Corps of dragging its feet.

The study outlines eight scenarios.

Lawmakers kick off 2014 with a budget surplus

"The state Legislature has kicked off its 2014 session. One of the first big debates of the new year will be about what to do with a projected budget surplus. Early estimates suggest the state will have hundreds of millions of dollars more than it expected," Rick Pluta reports.

State regulators investigate utilities' response to massive power outage

"State regulators will investigate how Michigan’s two largest electric utilities responded to a massive power outage last month. State regulators will not be investigating how the Lansing Board of Water and Light handled the same outage. They do not have jurisdiction over municipal utilities," Steve Carmody reports.

Polar vortex could stave off invasive species

"It might be difficult to think of this week's deep freeze as anything good, but scientists say the extreme cold could slow the migration of invasive species and kill some of the insect pests that have ravaged forests. Heavy ice could also prevent erosion and protect wetlands along big lakes," the Associated Press reports.

LANSING, Mich. (AP) - Michigan officials say after years of planning, they're ready to put in place a strategy for controlling the spread of invasive species in the state's waterways.

The plan is described in the annual "State of the Great Lakes" report released Thursday by the Department of Environmental Quality.

Aquatic invaders such as quagga mussels cost the region hundreds of millions of dollars a year.

The newly developed strategy focuses on early detection of new invaders and a rapid response to rein them in.

Imagine walking down a picturesque beach along Lake Michigan, and stumbling upon the carcasses of dead birds. That’s a very real and unpleasant problem along Lakes Michigan, Huron, Ontario and Erie. (It’s not as big of an issue in Lake Superior because of the lake’s colder water temperatures.)

Loons and other deep-diving birds are suffering from a disease called avian botulism. It’s form of food poisoning that kills wild birds in the Great Lakes ecosystem.

LANSING, Mich. (AP) - An invasive plant is spreading in Michigan waters.

The Department of Natural Resources says European frog-bit has been spotted in Saginaw Bay, Alpena and Chippewa County's Munuscong Bay. Until recently, the free-floating aquatic plant had been reported only in a few sites in the southeastern Lower Peninsula.

European frog-bit was released accidentally into Canadian waters in the 1930s. It has spread across Ontario and the Northeastern U.S.

There’s a lot of time, money and effort being spent to keep Asian carp out of the Great Lakes.

To keep them out, we first have to know where the carp are.

Biologists often go out and sample water from rivers and lakes to look for carp. They test the water for genetic material, and some of those tests have turned up positive for Asian carp.

Last year, 20 samples turned up positive hits in Lake Erie. The positive DNA hits raise alarm bells that an invasive carp species might be establishing a population in the Great Lakes.

But the presence of carp DNA does not mean an actual fish was swimming in that area.

This week, the Department of Natural Resources went through a big training drill that’s a first of its kind in Michigan. The drill is supposed to prepare the agency for what to do if the Asian carp makes its way into Michigan’s rivers.

A dozen boats stamped with the DNR logo line the shores of the St. Joseph River. Some of them are normal fishing boats.

But a few have these metal poles sticking out about three feet in front of the boat. At the end of each pole are these long pieces of metal cable that hang down in the water.

The DNR’s Todd Somers is the foreman of one of these homemade boats. He points out a 240-volt generator near the back of the boat. It can deliver up to 16 amps through the metal poles at the front of the boat; sending electric shocks through the cables into the river. That’ll stun any fish nearby.

Sea lamprey
Activistangler.com

DETROIT (AP) - A team with the U.S. Fish and Wildlife Service will estimate the abundance of sea lamprey in the Detroit River this month to determine what control measures might be needed.

The eel-like lamprey invaded the Great Lakes during the 1920s and has remained ever since. Lampreys attach to fish with a mouth resembling a suction cup. Their sharp teeth dig through a fish's scales and skin and feed on blood and body fluids.

The average lamprey will destroy up to 40 pounds of fish.

We have had many conversations on Stateside about invasive species, usually the type with scales and gills, such as Asian carp.

Today, we focus on invasive species with chlorophyll. Yes, non-native plants that are invading ecosystems in the Great Lakes.

Jo Latimore is an outreach specialist with the Department of Fisheries and Wildlife at Michigan State University, and she joined us today in the studio.

Listen to the full interview above.

Today we focused our attention on what it takes to run an auto company, and the future of Michigan’s automakers.

And, we met a real life "Rosie the Riveter." She helped turn out bombers at the Willow Run Bomber Plant nearly 70 years ago.

And, we a got a preview of this year's Traverse City Film Festival, which kicks off this week.

Also, we took a look at what invasive plant species are threatening the Great Lakes and what can be done to stop them.

And, more and more people are doing their shopping on their smart phones. We spoke with a man from Ann Arbor who created an app to help with mobile shopping.

Also, John Fierst with the Clarke Historical Library at Central Michigan University joined us to discuss Michigan In Letters, an online collection of letters that give insight to Michigan’s past.

First on the show, it's been just over a week since Detroit became the largest city in American history to file for bankruptcy protection under Chapter 9.

Until now, that unwanted distinction belonged to Stockton, California. 

Earlier this year, Bridge Magazine writer Ron French wrote an article about his visit to bankrupt Stockton and Vallejo, a California town that has emerged from bankruptcy.

As Ron puts it, if Stockton is an example of a city just being diagnosed with fiscal "cancer," Vallejo is a community that has finished chemotherapy. And so far nobody seems particularly thrilled with the results.

The National Wildlife Federation is suing the EPA over the agency's ballast water rules. The group says the rules are not stringent enough to stop invasive species from getting into U.S. waterways from ballast water discharges.

Invasive species found throughout the Great Lakes, such as quagga mussels, zebra mussels, round gobies, and spiny water fleas, most likely hitchhiked their way here in ballast water.

Here's how:

More on the NWF's lawsuit from the Duluth News Tribune:

The EPA in April announced its ballast water regulations after years of delays and actions by environmental groups to force the issue. But the National Wildlife Federation says the rules don’t go far enough to keep invasives out of U.S. waters, including the Great Lakes.

“The EPA’s permit will not adequately protect the Great Lakes and other U.S. waters from ballast water invaders. This weak permit leaves the door open for future harm to our environment and economy,” Marc Smith, senior policy manager for the group, said in announcing the suit. “We can do better — and need to do better — if we are to protect our fish and wildlife and their habitat for future generations.”

A farmer in Michigan could face up to $700,000 in fines for keeping a hybrid breed of pig if Michigan’s Attorney General’s office has its way.

Michigan’s Department of Natural Resources banned a species of wild Russian boar two years ago. The concern is that the pigs could escape from hunting reserves or farms and become hard to manage in the wild.

There are more than 11,000 inland lakes in Michigan, and a lot of us love to take boats out on them. But invasive species also like to catch a ride on boats, and that’s a major way they get from one lake to another.

You might see people wearing blue t-shirts when you go to a boat launch this summer. They’re with the program Clean Boats Clean Waters, and they want to show you a few things about where invasive species like to hide out.

A three day conference is getting underway in Marquette today, looking at the unique needs of cities on the Great Lakes and the St. Lawrence River.

More than a hundred American and Canadian cities are part of the group organizing the conference.

Dave Ulrich is the executive director of the Great Lakes and St. Lawrence Cities Initiative.

He says this year’s conference is focusing on the effects of climate change on Great Lakes cities, particularly on water levels on the lakes.

Wildlife managers could have a harder time controlling spawning Asian carp, if they escape into the Lake Michigan from Chicago-area shipping canals. That's according to a report released by the U.S. Geological Survey.

Elizabeth Murphy is a hydrologist with the USGS. She co-authored the study.

Murphy says new data shows fertilized Asian carp eggs can incubate in waterways that are only 16 miles long. That’s a lot less than the 62 miles scientists thought the drifting eggs needed.

Lawmakers in Lansing are quickly wrapping up the state budget for the next fiscal year. What will the $50 billion spending plan mean for you?

And, we took a look at the efforts to help prison inmates rebuild their lives through post-secondary education.

Also, we got an update on just how close the Asian Carp is to the Great Lakes.

First on the show, the Council of Great Lakes Governors met this past weekend on Mackinac Island.

The group talked of economic cooperation, and harmonizing plans for protecting the largest body of freshwater on the Earth’s surface. The discussions were mostly nice, but there were some disagreements, especially when it came to dealing with invasive species.

Michigan Public Radio’s Rick Pluta joined us today to explain.

The Council of Great Lakes Governors met this past weekend on Mackinac Island.

The group talked of economic cooperation, and harmonizing plans for protecting the largest body of freshwater on the Earth’s surface. The discussions were mostly nice, but there were some disagreements, especially when it came to dealing with invasive species like Asian carp.

Rick Pluta filed a story on their meeting, and we also got an update on where things stand with Asian carp. 

We spoke with Duane Chapman, a research fish biologist with the U.S. Geological Survey. Chapman said that there have been three Bighead carp that have been caught in the Great Lakes, but not since 2000.
