2 Cass County deer diagnosed with viral disease

A DNR official says epizootic hemorrhagic disease outbreaks are happening more frequently in Michigan, possibly because the biting flies that transmit the disease are pushing further north.

LANSING, Mich. (AP) - Michigan wildlife biologists say two deer in Cass County have been diagnosed with an often-fatal viral disease.

The deer tested positive for epizootic hemorrhagic disease, or EHD.

The Department of Natural Resources said Tuesday the disease is transmitted by a biting fly. It causes extensive bleeding. Infected deer lose their appetite and fear of humans, grow progressively weaker, develop a high fever and finally lose consciousness.

It's not believed that humans can get EHD.

DNR wildlife chief Russ Mason says there is no known way to treat or control the disease. Michigan has had several deer die-offs from EHD as far back as 1955. The latest covered six counties last year.

Mason says outbreaks are happening more frequently, possibly because climate change is driving the biting flies farther north.

Good news for rare songbird in Michigan

The Kirtland's warbler primarily nests in just a few counties in Michigan. The bird's population has been steadily increasing over the last 30 years in Michigan due to intense management practices.

Kirtland's warblers are moving south to their winter home in the Bahamas (lucky devils), but before they left Michigan, researchers counted 1,805 singing males.

That's less than the high in 2009 (1,826 singing males) but more than last year's count (1,773 singing males), and researchers say it's a sign of a healthy population.

The city of Lansing is expanding a  pilot recycling program. The ‘single stream’ recycling program means businesses and individuals don’t  have to separate bottles, newspapers and other recyclables. 

Chad Gamble is Lansing’s Public Works director. He says making recycling easier means more things will be recycled, and the more that's recycled the less the program costs the city.  

“There are several cities statewide that are doing ‘single stream’ collection in varying degrees.  But I think we are truly one of the leaders…branching out into the commercial recycling…the cart (residential) recycling for families and the public recycling.  And so, I’m very excited to pilot these programs." 

Gamble says city leaders are evaluating the ‘single stream’ recycling program and may eventually expand it to the entire city.

Reactor shut down after cooling system issue

The Palisades Nuclear Plant in southwestern Michigan has been shut down due to a loss of water in a cooling system. WWMT-TV reports the facility in Covert Township was shut down just before 3 p.m. Friday.

The lowest of four emergency classification levels was declared. The classification means plant workers were notified and were resolving the problem. Officials say the shutdown poses no risk to the public and that no radioactive materials were released.

A U.S. Nuclear Regulatory Commission inspection was held at the Van Buren County plant last month after a water pump component failed. The plant is owned by New Orleans-based Entergy Corporation.

Beachcombers rejoice, rights affirmed along Lake Erie

user nico paix Flickr

The Michigan Supreme Court settled a dispute like this back in 2005, after a neighbor had sued another neighbor for walking along their beachfront property.

The court ruled that the right to walk along beachfront property extends up to the ordinary high water mark in Michigan. The high water mark was defined, in-part, this way by the Michigan Supreme Court:

"The point on the bank or shore up to which the presence and action of the water is so continuous as to leave a distinct mark either by erosion, destruction or terrestrial vegetation, or other easily recognized characteristic."

Now, the Ohio Supreme Court has chimed in. From the Associated Press:

The Ohio Supreme Court has ruled that beachcombers can legally walk from the water to the "natural shoreline" along properties bordering Lake Erie.

The Wednesday ruling comes in a case pitting thousands of lakefront property owners against the Ohio Department of Natural Resources, which establishes public access rules.

In a 7-0 decision, the court reversed an appellate ruling that said property owners' rights extend to the point the shore and water meet on any given day.

The high court also rejected state arguments that public access should extend to a high water mark established in 1985.

Justices define the natural shoreline as "the line at which the water usually stands when free from disturbing causes."

It says its ruling reaffirms decisions dating to 1878 and state law enacted in 1917.

Michigan cities take a tree census

Grand Rapids, Adrian and Ann Arbor are taking part in a tree study that could help other Michigan cities assess their own urban forests. The goal is to make a tree assessment more accurate and affordable for cities.

Grand Rapids spent tens of thousands of dollars to find more information about the city’s trees. They came away with valuable information like how much greenhouse gases and water runoff the trees absorb. But city owned trees make up only a tiny portion of the overall urban forest in Grand Rapids.

Tyler Stevenson is the city forester. He says they discovered more than half of Grand Rapids’ trees are maples.

“Is that true for the entire community? We don’t know. And it’d be interesting information and it would also help to increase the awareness of the public on how valuable the trees on their property are.”

Federal officials will use the data from the study to enhance existing software. Other communities in Michigan will be able to use that software for free to calculate data about their own trees.

What we can learn from 3.5 million dead fish

Bill Fink is the Museum of Zoology's Curator of Fishes.
Photo by Rebecca Williams

Here in Michigan, we have the world’s largest collection of dead fish. At least, the world’s largest collection that’s based at a university.

There are about 3.5 million fish in this collection. It belongs to the Museum of Zoology at the University of Michigan.

Bill Fink is the director of the Museum of Zoology and Curator of Fishes.

He’s offered to take me on a guided tour. We take the elevator to the basement... where there’s row after row of shelves full of glass jars... full of fish.

“These specimens are from Japan and they were collected in 1920s – we have specimens that are well over a hundred years old now and they look fine.”

Bill Fink says these fish have been collected from all over the world, sometimes at great risk to the scientists. He points out the box of jars from Vietnam.

“They were collecting during war, the Mekong River Survey. They were shot at and captured and escaped and there were lots of adventures.”

Bill Fink is not just the curator here... he also goes out in the field. He says some of the fish themselves are dangerous for the collectors.

“We also have a huge collection of piranhas right here...I’ve been there when people have been bitten but I personally have not been bitten. I’m really careful.”

Fink shows me some amazing fish... like the tiny anglerfish with its appendage that glows in the dark at the bottom of the ocean.

An invasive insect may wipe out the ash trees at Sleeping Bear Dunes National Lakeshore. The emerald ash borer has infested up to 90 percent of the ash trees on the lakeshore's mainland in the northwestern Lower Peninsula. The first case was discovered in June and the tree-killing pest has spread quickly.

Lakeshore officials are considering their options to try to control the ash borer, but things look bleak.

Airplanes across the country use de-icing fluid, and airports have to figure out how to deal with the run-off from the fluid.

The Gerald R. Ford International Airport has come up with a $15 million plan to deal with the run-off which contains a substance called glycol. The Grand Rapids airport currently mixes glycol with storm water and dumps it into a tributary, where it breaks down and creates a bacterial slime.

Army Corps bumps up the juice on fish barrier to block carp

Fisheries biologists use electric probes in the Chicago Sanitary Ship Canal to find Asian carp near the electric fish barrier located in Romeoville, IL in 2009.
Petty Officer Bill Colclough U.S. Coast Guard

Officials at the U.S. Army Corps of Engineers Chicago District say they plan to pump up the electricity at their fish dispersal barrier along the Chicago Ship and Sanitary Canal. The increase is intended to repel smaller fish.

From the U.S. ACOE's statement:

While extensive research and monitoring indicate that small Asian carp currently are not currently within the vicinity of the fish barrier, and all field telemetry research indicates the barrier is highly effective, the Corps is taking this conservative approach to operating the electrical dispersal barrier out of an abundance of caution.

Corps officials say they'll turn up the power "later this fall."

In the statement, Corps officials say they have an aggressive monitoring program and have tracked nearly "1.9 million detections of tagged fish in the barrier area, with no indication of tagged fish having crossed any of the electric barriers in the upstream direction."

Environmental DNA (eDNA) evidence was found above the barrier leading some to wonder whether the fish are establishing themselves in waters close to the Great Lakes.

Officials at the Corps say while DNA testing has some advantages, but "eDNA does not provide conclusive proof of the physical presence of live fish."

Moose hunt opposed by Chippewa tribe in the U.P.

The DNR will soon decide whether a limited moose hunt will be held in Michigan.
MI DNR

It's up to the Michigan State legislature to determine what game is available for hunting in Michigan.

In late 2010, the legislature opened up the possibility of a moose hunt in Michigan.

They charged the Moose Hunting Advisory Council with developing recommendations on whether or not a moose hunt should be conducted. (You can let them know what you think by dropping them a line - moosecomments@michigan.gov).

The council is expected to present their report to the Michigan DNR's Natural Resources Commission next Thursday (September 15). The Associated Press reports that the Moose Hunting Advisory Council will recommend a moose hunt of 10 bull moose.

The NRC will take the recommendation and decide whether a hunt will occur.

But ahead of all that, the Inland Conservation Committee with the Sault Ste. Marie Tribe of Chippewa Indians voted to oppose the hunt.

Here's part of a statement from the tribe:

At its Aug. 1 meeting, the committee cited biological concerns of a hunt’s impact on a fragile and uncertain population of 433 moose. The proposed hunt would take 10 bull moose in the fall after the rutting season, according to news accounts. The Department of Natural Resources was officially notified of the decision last week.

The statement says "under the terms of the 2007 Inland Consent Decree, the committee's opposition effectively ends Michigan’s bid for a moose hunt, for now."

A spokeswoman for the DNR said the tribe's position will have no effect on the report going to the Natural Resources Commission next week.

If the NRC votes to establish a moose hunt in Michigan, the question of whether or not the tribe's opposition prohibits a hunt will have to be answered.

"Get up. Get out. And go see something we'll remember for the rest of our lives."

So says the new radio ad from Pure Michigan urging people to get outside and take in the fall colors in Michigan.

The ad is part of a TV and radio campaign that runs through mid-October according to the Detroit Free Press:

The budget is $2.4 million.

Among the new radio ads promoting Michigan tourism feature Holland and St. Ignace. They'll run in-state plus in Fort Wayne, Toledo and South Bend.

Other targets for "Pure Michigan" ads this fall are the good citizens of Chicago, Indianapolis, several Ohio cities, Milwaukee and Green Bay.

Platte Lake cleaner after years of salmon hatchery pollution

Platte Lake

Decades ago, residents sued to stop a fish hatchery in northern Michigan from polluting a lake. More than thirty years later, the legal battles have ended and the pollution has been greatly reduced.

Northern Michigan is home to some of the clearest blue lakes in the world, like Torch, Glen and Crystal.

Once upon a time Wilfred Sweicki says Platte Lake in Benzie County was in that league.

“It was extremely clear, never quite as clear as Crystal or Glen but nearly so.”

Unfortunately for Sweicki and other homeowners on Platte, fishery biologists did something nearby that changed the Great Lakes dramatically.

They planted Pacific salmon in the Platte River.

That was in the late sixties and soon a billion dollar fishery was born.

A hatchery was built and animal waste from millions of fish began pouring into Platte Lake. The waste contained the nutrient phosphorus.

Phosphorous caused algae to bloom, clouding the water and killing a variety of aquatic animals and plants.

It even caused chemical changes in the sediment of the lake bottom that produced milky clouds of a clay-like substance that collects on stones and docks.

DuPont promises to reimburse homeowners for trees killed by herbicide

Blue Spruce is one of the species of trees that can be affected by Imprelis.
Arthur Chapman Flickr

A few months ago, reports started coming in that an herbicide made by DuPont was hurting and killing trees. The Environmental Protection Agency recently ordered DuPont to stop selling the herbicide Imprelis. DuPont had suspended sales shortly before that. The herbicide was used by lawn care companies to kill weeds on lawns and golf courses starting last fall.

Bert Cregg is an associate professor of horticulture at Michigan State University.

He says Imprelis can cause a range of different injuries to blue spruce, Norway spruce and white pine.

“You might see like in a big white pine, you might see a little bit of top growth doesn’t look quite right, you’ll see the twisting and curling, stunting of the top of the tree, in other cases, yeah we’ve seen the tree killed outright.”

This week, DuPont announced a program to process damage claims from property owners. DuPont declined an interview. But in a statement, the company said property owners with approved claims will receive replacement trees – or cash compensation.

DuPont’s also facing a number of lawsuits, including a class action suit brought by a woman from Allen Park, Michigan.

Feds win lawsuit over drugs in Michigan cows

HAMILTON, Mich. (AP) - A judge says a western Michigan farm violated federal law by selling cows for slaughter with illegal levels of antibiotics.

Judge Gordon Quist ruled in favor of regulators who say Scenic View Dairy in Allegan County repeatedly ignored warnings about selling the cows for human consumption.

Quist didn't order a penalty last week and says he doesn't want to put Scenic View out of business. The judge told the farm and the government to come up with an agreement by the end of September.

Scenic View's primary business is milk but about 70 cows a week are sent to slaughter for human consumption. The farm claims there are exceptions to the government's drug rules. But the judge says
they don't fit.

Lead exposure affects kids' motor development

New research from the University of Michigan reinforces why it’s important to keep kids from being exposed to lead.

It’s long been known that relatively high blood lead levels can negatively affect children’s IQ.

This study finds it can also affect a child’s motor skills.

Dr. Howard Hu, a professor of environmental health sciences at the University of Michigan, studied children between the ages of three and seven in Chennai, India. Half the children studied had relatively high levels of lead in their blood. Those children tested significantly lower on motor skill tests… like using peg boards and copying pictures… than children with far less exposure to lead.

Dr. Hu says the Indian children’s blood lead levels are about two to three times that of American children. Lead is still a problem in Michigan, with children still being exposed to aging lead paint in homes, lead in pipes, and lead contamination in soil.
