We’ve been bringing you reports from the series, ‘Ten Threats to the Great Lakes’ which is now looking at the threat to beaches. Our guide through the series is Lester Graham. He reports that scientists are beginning to understand what’s killing thousands of Great Lakes shorebirds. It might be part of a larger problem indirectly caused by humans.


Researchers are beginning to understand what’s killing thousands of
Great Lakes shorebirds. It might be part of a larger problem indirectly
caused by humans. The Great Lakes Radio Consortium’s Lester Graham
reports:


Along parts of Lake Erie, Lake Ontario, and Lake Huron, large numbers
of dead birds and fish are washing up on shore. If they’re left there, the
disease that killed them can be passed on to other wildlife. That’s why
park officials such as Mike Mumau at Presque Isle State Park at Erie,
Pennsylvania ask their staff to watch out for the dead carcasses.


“Our interns do a great job. They’re the eyes of the staff that are out. So,
there’s probably three to four days a week that they’re out on the
beaches, checking to see if they have anything.”


Since 1998, untold numbers of fish and sometimes hundreds of dead
birds a year have washed up on just these eight miles of Lake Erie beach.


Eventually, researchers figured out the problem: type “E” botulism. It
slowly paralyzes the birds until the respiratory system shuts down. Most
of them don’t make it that long. They get so weak they can’t hold their
heads up out of the water and they drown.


(Sounds of walking and shovel)


Leslie Jones and her fellow interns are headed out to an area to pick up
some dead seagulls on the beach.


“When we’re out here doing migratory bird studies, we might see some
and then we pick them up as soon as possible. A lot of times, we get
radioed from different people like lifeguards and they have us come out
and pick them up so that the disease doesn’t spread throughout the rest of
the ecosystem.”


They find five dead birds rotting on the beach. They bury the maggots
because they could carry the botulism toxin and other birds might eat the
maggots. They shovel the bird carcass into a black plastic garbage bag.


“If they’re very fresh, this one, obviously not very fresh, but, if we get a
fresh one, we actually freeze them and they’re sent off to be tested
botulism, but, something like this we’ll just bag up until we can get them
incinerated to get rid of all the disease.”


The fresh carcasses are shipped to the National Wildlife Health Center in
Madison, Wisconsin.


There, Grace McLaughlin is among the researchers who are beginning to
put the puzzle together.

Here’s what they think is happening. The invasive species zebra mussels
and quagga mussels create huge mussel beds that begin a complicated
biological phenomenon. Organic matter collects there, and then decays. It
lowers the oxygen level in the immediate area of the mussel beds. Type
“E” botulism spores occur naturally, but when the oxygen level goes
down, they begin reproducing like crazy. The waste they produce is the
toxin.


“That toxin will accumulate in the organic matter as well as in the water
in the immediate vicinity of the mussel beds. As the mussels do their
filter feeding, they will accumulate the toxin in their tissue. They are not
susceptible to the toxin. However, when the fish start coming down
there and eating the mussels, they become intoxicated, lose their ability
to swim properly and become easy prey for the birds that come in.”


The fish that feeds on the mussels the most is another invasive species,
the round goby. Researchers made the connection when they noticed the
botulism started being a problem shortly after round gobies arrived in big
numbers.


The type “E” botulism toxin has killed tens-of-thousands of birds such as
cormorants, terns, loons, ducks, and seagulls.


Back at Presque Isle State Park, Mike Mumau says it’s terrible to see so
many birds die.


“We just do our best on our end to stop the botulism cycle. When we
can, provide samples, and also, keep it a positive recreational experience
for all our visitors. They don’t want to see birds decomposing and
rotting out on the beaches, so we’re pretty diligent with that.”


Researchers say that’s about the best that can be done. Since ocean-
going vessels brought zebra mussels, quagga mussels, and round gobies
to the Great Lakes, all three of the invasive species have flourished. It
will likely be a long time before we’ll ever begin to understand the full
extent of the damage to the native wildlife of the lakes.

Ten Threats: Coastal Development Pressures

One of the more subtle but relentless threats to the Great Lakes is
coastal development. Condos, ever larger and nicer beach homes
and buildings and parking lots in the watershed all have an
impact on the Lakes. As the population grows and the suburban
lifestyle keeps spreading, the health of the lakes is compromised
in countless tiny ways. Reporter Peter Payette finds those tiny
ways all add up:

We’re continuing our look at ‘Ten Threats to the Great Lakes.’
Lester Graham is our guide through the series. He says the
experts who were surveyed to determine the threats say rapid
development is among the problems affecting the lakes:


One of the more subtle but relentless threats to the Great Lakes is
coastal development. Condos, ever larger and nicer beach homes
and buildings and parking lots in the watershed all have an
impact on the Lakes. As the population grows and the suburban
lifestyle keeps spreading, the health of the lakes is compromised
in countless tiny ways. Reporter Peter Payette finds those tiny
ways all add up:


Greg Reisig is standing at the edge of a 20-acre construction site
just down the street from the shore Lake Michigan.


Below him is a man-made pond a few hundred feet long. It was a
dry summer around here, but the pond is full.


In fact, Reisig says the water level is always the same.


“And that indicates there’s a lot of ground water flowing
here…there’s a lot of water in this pond and you can see what
was a whole big wetland complex…there’s a lot of cedar and red
osier dogwood…all the wetland plants.”


There are no wetlands here now.


The site in northern Michigan was excavated for homes a few
years ago.


But now the Army Corps of Engineers says the wetlands that
were here need to be restored. A few acres likely will be
restored. But Reisig says almost the whole site was wetlands
once. He expects it will soon be a subdivision with not much
more than a drainage ditch connecting it to Lake Michigan.


“What will that do to the amount of flow of water going into the
bay? Because of hard road surfaces, hard driveways, roofs,
buildings and supposedly fertilized lawns. What will happen to
the water and how will that increase the flow to the bay?”


The developer’s attorney says this is nonsense. Matt Vermetten
says this land was heavily farmed and mined for clay.


“There are pockets of quote unquote wetland and those are there
because of excavation for clay. So is this a wetland complex of
the nature we speak of when we typically speak of such a thing? I
think not.”


Disputes like this are becoming more common around the Great
Lakes. John Nelson is the baykeeper with the Grand Traverse
Bay Watershed Center. The bay off Lake Michigan and attracts a
lot of people. But Nelson says development doesn’t have to be a
problem.


He says the problem is people don’t think about the ecology of
the lakes. For example, east of Traverse City, Michigan, resorts
dominate the coastline. Along the beach, thick stands of sedges
and rushes extend out a few hundred feet. But the sections of
dark green marsh alternate with stretches of clean sand and white
lawn chairs.


(birds calling on beach)


Nelson grew up here and says this part of the lake was never a
sugar sand beach.


“They’ve located in a coastal marsh. Instead of celebrating and
dealing with that they’ve chosen to see it as they would like to
have it and then change it.”


The impacts of the changes are cumulative. Fish and wildlife
habitat is fragmented. The natural filtering properties of the
wetlands are gone.


So every time the city gets a rain shower all the dust and grime
and pollution are washed right into the lake.


Census data show people are leaving many of the Great Lakes
coastal cities and spreading out along the coastline. But it’s not
clear how local governments should plan for the growth.


Mike Klepinger studies land use planning for the Michigan Sea
Grant program. He says it’s hard to make direct connections
between a healthy lake and particular land uses.


“We are getting more planning along the shoreline than we had
thirty years ago in the state. The number of counties and number
of townships that have a plan has gone up, for example. But we
don’t know whether those plans are really doing any good.”


And it’s hard to implement good planning on a broad basis. In
any area, dozens of different local governments might have
independent control over development.


Multiply that by the number cities, townships and counties along
the coasts of the Great Lakes… and it’s hard to see how it all can
be managed so that enough coastline habitat is preserved.

Some environmentalists are outraged that a Michigan Member of Congress blocked a bill to permanently ban oil and gas drilling in the Great Lakes. The Great Lakes Radio Consortium’s Lester Graham reports:


Republican Congressman Mike Rogers blocked a bi-partisan federal effort to ban drilling in the Great Lakes. Rogers’ office says taking state control away on drilling could lead to taking state control away on other issues such as water withdrawal. He doesn’t want the more politically powerful arid Southwest states using it as a precedent to take federal control of the Great Lakes.


Cyndi Roper is with the environmental group, Clean Water Action. Her group and others say under the guise of protecting the Great Lakes, Rogers is actually exposing the Lakes to new risks.


“By putting a ban on oil and gas drilling in the Great Lakes, this isn’t an issue of control of the Great Lakes, it’s an issue of protecting the Great Lakes.”


There is a moratorium on new drilling on the Lakes that expires in 2007. It will then be up to each individual state to decide whether to allow new drilling.

Congressman Skeptical of Great Lakes Planning Effort

  • The Great Lakes Restoration and Protection Strategy is being drafted, but some worry that the meetings being held are more conducive to talking than actual planning. (Photo courtesy of the EPA)

Last year, President George W. Bush ordered federal agencies to work with Great Lakes states, towns, and tribes to design a strategy to restore and protect the Great Lakes. An inter-agency task force is planning a summit this summer to release its plan. But some members of Congress are skeptical. They see the regional collaboration meetings as another chance for government to talk about a problem rather than do something about the problem.

Last year, President George W. Bush ordered federal agencies to work with
Great Lakes states, towns, and tribes to design a strategy to restore and
protect the Great Lakes. An inter-agency task force is planning a summit
this summer to release its plan. But some members of Congress are
skeptical. They see the regional collaboration meetings as another chance
for government to talk about a problem rather than do something about the
problem. The Great Lakes Radio Consortium’s Lester Graham reports:


All the different agencies and people are working on the draft of the Great
Lakes Restoration and Protection Strategy right now. It’s scheduled to be
released in July.


When the former Environmental Protection Agency Administrator, Mike Leavitt
first started talking about the regional plan last summer, he outlined it as
a way to spend tax dollars better.


“We have 140 different programs right now and I’m interested to make certain
we know how those dollars are being spent and that using to them to the maximum
efficiency, then we’ll have a plan, I hope, regionally, as to how to move
forward.”


But, in the meantime, major funding for some projects has been put on hold. Rahm Emanuel is, to say the least, skeptical of the process. Emanuel is a Member of Congress, a Democrat, from Chicago. He wonders what good this task force ordered by the President will do.


“Well, look. At least there’s an acknowledgement that the Great Lakes, Lake
Michigan and the other Great Lakes, need a focus and a strategy. But, we
know today everything that has to be done and it’s going to require
resources.”


But President Bush says he wants to coordinate the efforts of the federal
agencies so there’s less duplication and conflict between agencies, the
states, the cities and the tribes. Congressman Emanuel says that’s fine,
but there have already been lots of meetings, lots of studies and strategies
mapped out.


“My flashing yellow light here is I don’t want to waste more time on more
studies, more time on more talk when Michigan knows what it needs to do,
Wisconsin knows what it needs to do its part, and Illinois and Indiana know
what they got to do.”


Emanuel says everybody pretty much knows the job at hand. The problem is
money. And that’s where he thinks the Bush Administration is playing games.


“Are we doing this to stall, and not as a way of avoiding the hard, hard job
of putting resources toward proven strategies?”


Environmentalists are gearing up to make sure than the strategy to protect
and restore the Lakes isn’t just another piece of paper. They want the
federal, state, and local governments to draft a real plan, then
follow through, including finding the money that can actually make
something happen in the Great Lakes.

LOOKING AHEAD TO 2005’s GREAT LAKES ISSUES

This coming year will likely see some major policy decisions regarding the Great Lakes. Because the lakes stretch out along eight states in the U.S. and two provinces in Canada, getting all the governments to agree on issues is a long and sometimes trying process. But… those involved think 2005 will be the year that some real progress on Great Lakes issues will be made. The Great Lakes Radio Consortium’s Lester Graham recently talked with the Chair of the U.S. Section of the International Joint Commission, Dennis Schornack.

This coming year likely will see some major policy decisions regarding the Great Lakes. Because the Lakes stretch out along eight states in the U.S. and two provinces in Canada, getting all the governments to agree on issues is a long and sometimes trying process. But those involved think 2005 will be the year that some real progress on Great Lakes issues will be made. The Great Lakes Radio Consortium’s Lester Graham recently talked with the chair of the U.S. Section of the International Joint Commission, Dennis Schornack. The IJC deals with disputes and advises the U.S. and Canadian governments on issues regarding the Great Lakes:


The International Joint Commission and the Government Accountability Office both have been critical of the U.S. government for not finding clear leadership on Great Lakes issues. Different agencies sometimes find their efforts overlap or conflict with others. At times, it seems there’s no organized effort to restore the health of the Great Lakes. Dennis Schornack says he thinks things were starting to get better because recently appointed U.S. Environmental Protection Agency Administrator Mike Leavitt took a real interest in the Great Lakes. But now Leavitt is leaving to become the new Health and Human Services chief.


“It’s going to be hard to beat the enthusiasm of Mike Leavitt. He spent literally about fifty percent of his time as EPA Administrator in the Great Lakes throughout. He was everywhere this past summer. But it does fall to the new administrator, whomever he or she may be; but in the meantime, the governors and mayors are proceeding forward on the priorities that they set over a year ago, and fleshing those out into very tight kinds of recommendations.”


Countless studies and reports on the Great Lakes point out one of the biggest threats to the lakes is invasive species. Those are foreign critters such as zebra mussels and round gobies that hitchhike in the ballast water of cargo ships, or are introduced unintentionally. Often the invasives damage the native fish, plants, and ecosystems of the Great Lakes. Nothing has been done to effectively stop importing the invasives, and some have gone so far as to suggest that the St. Lawrence Seaway connecting the Great Lakes to the Atlantic Ocean should be closed. The IJC’s Dennis Schornack says he’s hopeful that we’ll soon see laws that will do more to help prevent invasive species from getting into the Lakes.


“In the United States, at least, there is pending legislation that has been pending for over two years now called the National Aquatic Invasive Species Act. This legislation is overdue. It’s time for Congress to act on it. And in the ’05 legislative Congressional year, it’s time for them to act. And that’s the place where the standards get set, the authority gets established and where all of the rubber really hits the road. Now, that’s just in the United States. Bi-nationally, because the Great Lakes are a shared resource, the IJC, that I’m the chair of the U.S. section, has continued to advocate cooperation and collaboration between the two countries in terms of at least setting a common standard, a common rule, common regulation on the Great Lakes. Because, obviously, setting it on one side of the boundary line doesn’t do any good if the other side doesn’t follow.”


Another issue that’s recieved a lot of attention in the Great Lakes region recently is water diversion. A document called Annex 2001 tackles the issue of how much water can be used or withdrawn from the Lakes. The various state governors and province premiers put together draft agreements for public comment. Schornack says there’s been a huge response, and a lot of it hasn’t been positive.


“They recieved, I think, over ten-thousand public comments. And there is differing viewpoint, a growing difference between the view taken in Canada and the view taken in the United States on this effort. Canada, the province of Ontario, has come out and point-blank opposed the existing documents. There are concerns in Canada that this is just some kind of a ruse to somehow allow diversions of the Great Lakes waters to occur. I’m not part of that viewpoint, to tell you the truth. What’s being done right now and what will happen in 2005 is that the comments are being digested, we’ll see new draft documents come out from the governors and premiers and hopefully begin the process making those agreements stick.”


Schornack says 2005 will also see some important reports on the economic costs of invasive species. Studies on the logistics of shipping, cargo ship traffic and alternative freight haulers and design plans that look at the total cost of shipping – including the infrastructure costs and the environmental damage caused by invasive species. It should be an interesting year for the Great Lake if Congress moves on key issues, and then finds money to make the Great Lakes more sound.

Gl States Speak Up on Ballast Water Lawsuit

A lawsuit brought by several environmental groups in California seeks to increase protection against invasive species. The groups hope to force the Environmental Protection Agency to regulate ballast water discharge. Now, officials from the eight Great Lakes states are writing-in to support these groups in their lawsuit. The Great Lakes Radio Consortium’s Celeste Headlee reports:

A lawsuit brought by several environmental groups in California seeks
to increase protection against invasive species by forcing the
Environmental Protection Agency to regulate ballast water discharge.
Now, officials from the eight Great Lakes states are writing in to
support these groups in their lawsuit. The Great Lakes Radio
Consortium’s Celeste Headlee reports:


Researchers say ballast water from oceangoing ships is one of the
primary methods by which invasive species enter the Great Lakes.
State Attorney General Mike Cox wrote the amicus brief for Michigan.
He says under current EPA rules any ship that claims it doesn’t have
ballast can, in fact, issue discharge into the water.


“Now we know that right now and on any given day, about 85 to 90
percent of these ships claim that they don’t have any ballast on board.
That’s a claim that stretches credulity, quite simply because all ships
need ballast if they don’t have cargo.”


The National Oceanic and Atmospheric Administration estimates that it
costs 45 million dollars a year just to control zebra mussels and sea
lampreys in the Great Lakes. Cox and the seven other Great Lakes
Attorneys General say the EPA must do more to protect the waters from
invasive species. The AGs have filed eight separate amicus briefs
supporting the case against the government. For the Great Lakes Radio
Consortium, I’m Celeste Headlee.
