People have been saving seeds for thousands of years. Gardeners save
seeds of their favorite plants. Governments save seeds to protect
their food crops. Now, some people are freezing the seeds from trees.
That’s because the trees are being destroyed by an insect pest.
Rebecca Williams reports they’re hoping a gene bank will protect the
trees’ DNA and some day help bring the trees back:


Seeds are a pretty amazing little package. They might be small, but
they’re tough. They can live through very dry and very cold
conditions.


(Sound of seed being shaken out of a paper bag)


These seeds are from ash trees. In some parts of the Upper Midwest and
Ontario, ash trees have been wiped out. The seeds are all that’s left.
That’s because of the emerald ash borer. It’s a tiny green beetle that
got into the US in cargo shipped from China. So far, the beetles have
killed 20 million ash trees. No one’s been able to stop the beetles
from spreading.


David Burgdorf works for a lab with the US Department of Agriculture.
He says people might not even know they had ash trees until the trees
got attacked:


“If your lawn was filled with the ash tree and you had all this great
shade and your energy bills were low, but now the ash tree’s gone, you
only miss it when it’s gone.”


Burgdorf says a lot of people love ash trees for their gold and purple
fall colors. They grow fast and hold up well under ice storms. Native
American tribes depend on black ash for making baskets and medicine.


David Burgdorf is trying to make sure ash trees won’t disappear completely
if the beetle spreads across the country. He’s gathering ash seeds
sent in by volunteers. He’s hoping to build a collection that
represents the entire ash tree gene pool:


“We want to try not to have to bring something back. We don’t want it
to be extinct. It’s important we at least save the seed so we can maybe cross
it, or do something, breed in resistance to the tree and have it
available to come back.”


Burgdorf says he thinks of the seeds as an investment for the future.
The seeds are definitely being treated like a precious commodity.
They’re sorted and they’re X-rayed to make sure the living embryos in
the seeds haven’t been damaged.


Then, the very best seeds in the bunch are off to a high security
government vault:


“We kind of joke that it’s the Fort Knox for seeds.”


Dave Ellis is the seed curator at the National Center for Genetic
Resources Preservation. It’s a giant seed bank. Ellis says the ash
seeds are dehydrated and frozen at 0 degrees Fahrenheit. These steps
put the seeds into a deep sleep:


“In a dehydrated state, degradation of DNA happens much more slowly,
over a course of tens of years or hundreds of years.”


Ellis says the ash seeds should be viable for at least 25 years, if not
longer. He says researchers might be able to use the stored genetic
material to breed new pest-resistant ash trees in the future. Ellis
sees gene banks as a safeguard against a world that’s changing fast.


Scientists say wild plants and crops we depend on will face many new
threats. Climate change might bring more drought.
Escalating global trade could mean importing more pests.


Deb McCullough studies insect pests at Michigan State University. She
says any time you import cargo, you’re running the risk of also
importing pests that can run up huge bills. She says in North America,
one of the big concerns is imports from China:


“If you look at the latitude where China occurs, if you look at the
northern and southern latitude and you overlay that on top of the US and
Canada, it matches up almost perfectly. So you can figure that pretty
much any kind of climate or habitat you find in China, there’s going to
be something similar in the US.”


McCullough says not everything that gets in will turn out to be a pest,
but she says as China’s huge trade surplus with the US grows, there’s a
greater risk more pests will come in.


She says there are some new regulations in place, but restricting
international shipping is a tricky proposition. McCullough says seed
collecting might be one way to preserve plants we rely on:


“People who are molecular biologists, the gene jockeys, have gotten
very good at enhancing or producing resistant varieties of different
kinds of plants. So, that may be something that becomes an option in the
future, maybe not the too distant future.”


McCullough points out there will be serious debate about introducing a
genetically modified tree into the wild. Some people don’t like the
idea of manipulating the genetic makeup of plants or animals.


There are a lot of questions about what might be done with the frozen
seeds, but the seed collectors say regardless, they need to bank up the
DNA of plants that we’re in danger of losing.

Blazing New Atv Trails in Parkland

Managers at state parks across the country are scrambling to figure out how to deal with a

Managers at state parks across the country are scrambling to figure out how to deal with a
rising demand for trails for All-Terrain Vehicles. Stephanie Hemphill reports park
managers are finding it’s not easy to satisfy both fans who have fun on four wheel drive
vehicles and people who want a quieter time in the park:


As the name suggests, All-Terrain Vehicles are built to travel rough. ATVs power over
rocks and logs. Their go-anywhere knobby tires grip the land and take their riders just
about anywhere they want to go, and a lot of them want to go to public parks.


Whether it’s forests, dunes, bogs or a desert, riders say four-wheeling can be a fun way to
get out into nature. The vehicles are popular. Dealers are selling close to a million ATVs
every year, and sales are growing steadily. With that many people looking for a place to
play, states are scrambling to accommodate them.


In Minnesota, the state decided a long ATV trail might be a good way to attract tourism
dollars to a struggling rural area in the state.


Ron Sluka jumped at the idea. He’s the trail coordinator for a local ATV club. He’d been
wanting for years to build a trail in his area. Then he heard the state would pay for a
“destination” trail so well-built and attractive, people would come from all over to ride it.
Sluka thought it would be great news for his area.


He and county officials worked up a plan, but when it hit the local news, Sluka says a
few people raised a ruckus:


“The way it was presented to the people, eminent domain would take over in cases if
need be, and there were going to be up to 20 feet of your land taken for this trail. None
of the above is true, totally none of it is true, absolutely zero. But it’s too late: once
things are rolling, it’s rolling.”


Sluka says now, it’s hard to get a rational discussion of the issues. Beyond property rights
issues and worries about the ATVs being too loud, there are other concerns:


“The residents have kind of been left out of the loop.”


That’s Deb Pomroy. She lives near the proposed ATV trail.


Pomroy says most of her neighbors don’t mind the local ATV riders. It’s that idea of
drawing ATVs from all over the state that freaks them out, and Pomroy has her own reasons
for opposing a trail here, where the Cloquet River has its beginning: wood turtles.
Pomroy is a biologist. She says this area is a refuge for the turtles. They’re endangered in
most of their range, and listed as a threatened species in Minnesota.


Wood turtles bury their eggs in sandy soil. Pomroy says they would love to bury their
eggs in soil disturbed by ATVs, but the eggs wouldn’t survive:


“Even stepping on a nest, which is buried in soil, don’t know there are eggs there, is
enough to destroy the eggs.”


The trail is on hold for now, while county officials and ATV riders try to come up with
an alternative. Concern about damage to sensitive environmental areas is one of the chief
reasons many environmentalists don’t like the idea of letting ATVs into parks.


Jason Kiely is with Wildlands CPR, a national non-profit group that works to prevent off-
road vehicle damage on public land. He says fights over ATV trails are inevitable, as
long as public agencies don’t involve all park users in a comprehensive planning process.


“Primarily because off-road vehicles affect every other use of the forest so significantly.
So we advocate for doing comprehensive travel and recreation planning, not just trying to
carve off the ATV piece, but multi-stakeholder planning efforts that offer something to
everyone.”


Kiely says the US Forest Service and many state agencies have a lot of work to do, to
find the right balance between preserving nature and allowing ATV riders to have their
fun on public land

States Struggle to Control Ash Borer

A tiny green beetle is killing millions of ash trees. And so far nobody’s
found a way to stop it in its tracks. The GLRC’s Rebecca Williams reports cities and states are struggling to find money to keep the beetle from spreading:

A tiny green beetle is killing millions of ash trees. And so far nobody’s
found a way to stop it in its tracks. The GLRC’s Rebecca Williams
reports cities and states are struggling to find money to keep the beetle
from spreading:


Once emerald ash borers chew their way into your ash trees, there’s
pretty much only one thing you can do.


(Sound of chainsaw and tree cracking and falling)


Crews here have been sawing down and chipping up trees six days a
week. In some places, crews are cutting down both dead and live trees.
Dead trees are a safety hazard. Cutting live trees near infested areas can
help contain the beetles.


The emerald ash borer is native to China. Scientists think it got in on
wood packing crates more than ten years ago. The emerald ash borer eats
through the living part of the tree just underneath the bark. The beetles
cut off the tree’s water and food supply… so it starves to death. 15
million ash trees are dead or dying in Michigan. Hundreds of thousands
are dying in Ohio, Indiana and Ontario, and it could spread to other states
soon.


Some cities have been hit really hard. For example, some of the trees in
Ann Arbor, Michigan have been dead for a couple of years. Kay
Sichenader is the city’s forester. She says she’s worried about limbs
breaking off trees, or bark falling off in 80 pound chunks.


“There’s some terrifically bad ones out there. Nothing will make me
happier than when those trees are down, I gotta tell you.”


This isn’t the first time cities have lost big shade trees. Dutch elm
disease almost wiped out American elms in the 1960’s and 70’s. It’s a
little ironic: people planted ash trees to replace the elms because they
thought ash trees were invincible.


That love of ash trees means cities are losing 20 or 30 percent of their
trees, and they’re spending millions of dollars to take trees out.


Forester Kay Sichenader says her city normally takes out a thousand old
trees a year. Now, she’s got ten times as many trees to cut down.


“If I never bumped it up, and we just remained with our thousand a year,
we would never change because it would take me ten years to get the ash
out. In the meantime I’d have 10,000 more dead trees to deal with. It’s
sobering.”


Sichenader says the city’s trying to get the dead ash trees out as fast as
they can. She’s contracted five extra crews to saw down trees. She
hopes they’ll be done by the end of the year, but it might be longer.


Many homeowners are getting impatient. They’re worried about big
branches falling on their cars or homes. Or worse, falling on their kids.


Laura Lee Hayes lives in a cul-de-sac with four infested ash trees. She
points out a big branch on her neighbor’s dead tree.


“This whole piece is just laying here, ready to pull off, and there are
small children that play in this yard. That’s why I look to my city to get
over here and get these trees down. There’s a real frightening aspect to
that.”


Hayes says she tried to pay to take the trees down herself, but she found
out it would’ve cost more than a thousand dollars.


In Indiana, homeowners now have to spend their own money to get rid of
dead trees in their yards. State officials say they can’t afford to keep
cutting down live ash trees to slow the infestation. The state won’t be
giving money to help cities cut down dead trees either. That could mean
the emerald ash borer will spread unchecked.


At first, the federal government sent states several million dollars to fight
the beetle, but now the money’s just trickling in. In 2004, Michigan
Governor Jennifer Granholm asked President Bush to declare the state a
federal disaster area. That request was denied. Recently, officials in
Ohio and Michigan said they’ll have to cut back on containing new
infestations.


These trends worry scientists.


Deb McCullough is a forest entomologist at Michigan State University.
She says states barely have enough money to monitor how far the beetle’s
spreading, and she says a lot more money’s needed for ad campaigns to
tell people to stop moving firewood. The beetle spreads fastest when
campers or hunters move infested wood.


“You have to look down the road, and either you spend millions of
dollars today to try to contain emerald ash borer or we’re going to be
looking at losses in the tens of billions of dollars in the future, and it’s not
too distant of a future.”


McCullough says if more funding doesn’t come in states might need to
have timber sales to take ash out before the beetle kills it. And cities will
still be paying millions of dollars to take out dead trees. That means
people who live in those cities might see cuts in other programs or have
to pay higher taxes.


Deb McCullough says the economic impacts are serious… but the
environmental impacts could be even worse. She says it’s hard to know
how wildlife might be affected if we continue to lose millions of ash
trees.

Trade Increasing Number of Exotic Species

Exotic insects and diseases that attack plants can be very destructive and
cost millions of dollars to fight. Just ask those cities fighting the
invasion of the emerald ash borer and the Asian longhorned beetle. The
Great Lakes Radio Consortium’s Rebecca Williams reports… a recent
study looks at where new potential pests are coming from:


Inspectors at airports, ports and borders nab between 40 and 60 thousand
different potential plant pests each year. That’s according to a study in
the journal, Biological Invasions.


Author Deb McCullough says global trade is leading to an increase in the
number of non-native insects and diseases that could become problems.


“China in particular which has become one of our major trading
partners…most of the kinds of climate that you’ll find in China, you’ll
find somewhere here in the U.S., and there’s really an awful lot of
opportunities for exotic insects to become established here.”


McCullough says it’s hard to estimate how many new potential pests
could be slipping past inspectors. She says at best, inspectors go through
just 2% of agricultural cargo coming into the U.S. each year.

Beetle Threatens Anishinabe’s Ash Trees

  • Emerald Ash borer is a type of beetle that is threatening black ash trees. (Photo courtesy of USFS)

American Indians have been making baskets from the wood
of black ash trees for hundreds of years. Now, they see that tradition threatened by a beetle. The emerald ash borer has killed millions of ash trees in Lower Michigan over the past few years, and Indian basket makers are preparing for the day when their grandchildren may no longer find black ash. The Great Lakes Radio Consortium’s Bob Allen
reports:

American Indians have been making baskets from the wood of black ash trees
for hundreds of years. Now, they see that tradition threatened by a beetle. The
emerald ash borer has killed millions of ash trees in Lower Michigan over the
past few years, and Indian basket makers are preparing for the day when their
grandchildren may no longer find black ash. The Great Lakes Radio
Consortium’s Bob Allen reports:


(Sound of museum)


The Anishinabe believe the black ash tree is a gift to their people, and they say
its carried them through many hard times. The story of the baskets is part of a
display in the Ziibiwing Center at the Saginaw Chippewa Reservation in
central Michigan.


Judy Pamp is assistant director of the Center, and she remembers how
important baskets were when she was growing up.


“If we ate it was because there were baskets to sell or trade, and it went from
that being the thing that sustained us to where now it’s more of a an art and a rare art,
and that you do in limited quantities.”


Pamp comes from a long line of basket makers, and she’d like to pass on the
skills to her granddaughter, but she says the baskets aren’t the most
important thing… rather it’s a sense of connection among the generations.


“You know the whole family pulling together, the whole community pulling
together to help one another out… that everybody was important and
everybody had their role.”


Some family members may be good at one part of the basket making, and
there’s plenty of work to divvy up. First, there’s going into a swamp to find a
black ash tree, cut it down and haul it out.


(Sound of pounding)


Then, there’s peeling off the bark, and pounding the wood into strips, called
splints, for baskets. All that can take 25 hours of hand labor. Then, it’s
another 6 or 8 hours to weave a basket. Without the trees, basket makers worry
they may lose that closeness of working together.


The emerald ash borer isn’t on tribal lands yet, but it’s in
two neighboring counties. Scientists say it’s only a matter of time before the
beetle invades the reservation and wipes out the ash tree. The invasive pest got
to the U.S. in cargo shipped from Asia. Despite quarantines the bug continues to
spread because people move infested firewood, timber or landscape trees.


Deb McCullough is an entomologist at Michigan State University. She
concedes ash trees in Lower Michigan are goners.


“Took me a while to get my mind around that. You know we’re going to see
somewhere probably in the neighborhood of four hundred million ash trees in the forests
of lower Michigan that eventually are going to succumb to emerald ash borer
unless something really amazing happens in the next few years.”


McCullough says they’re looking for a way to help trees resist the insect, or a
predator to keep it in check, but it might be years before a solution is found.
So, the tribes are looking at their own ways to deal with the ash borer.


(Sound of splint pulling)


One idea is to harvest a whole bunch of black ash splints for baskets and freeze
them to use later. That would keep basket making going for a while.


(Sound of basket maker)


Another plan is to collect and save seeds from black ash trees.


Basket maker Renee Dillard says someday maybe trees can be replanted from
seed, but she says that means forty or fifty years before any wood is
harvestable, and she doesn’t think she’ll be around then to teach her
grandchildren how to choose the right tree and pound out the splints.


(Sound of pounding)


“As a people, we’re pretty resilient and we can adapt to change. It’s just that we’re
losing an important part of that whole black ash process, and I don’t want my great
grandchildren to just make baskets. They need to understand the whole process because
it’s done carefully and prayerfully.”


Dillard follows the old ways. She lays down tobacco as an offering of thanks for the tree,
and she believes this calls her ancestors to witness her use of the gift.


The Anishinabe don’t know why the emerald ash borer is taking their trees at
this time, but their tradition teaches for every hardship there will be an answer
and something to balance the loss.

Powering a Town With Manure

Large-scale livestock farms struggle with ways to dispose of their animal waste.

Large scale livestock farms struggle with ways to dispose of their
animal waste. Now, efforts are under way to make an Indiana town the first
in the nation to get its power entirely from hog manure, but as the Great
Lakes Radio Consortium’s Chris Lehman reports, this venture has a long way
to go before it becomes a reality:


Indiana Agriculture Department officials have unofficially renamed the
village of Reynolds as Bio-Town USA. They hope to supply the town’s power
needs with energy produced from animal waste. The technology to convert the
so-called biomass into usable power is in its infancy.


Agriculture Department spokeswoman, Deb Abbott, admits the project is venturing
into some uncharted territory.


“We don’t have all the answers. We’re gonna look for the answers and we
don’t have an exact time frame.”


Abbott says Reynolds was chosen because it’s a typical mid-west small town.
It also has easy access to manure. The state estimates more than
150-thousand hogs are within a 15-mile radius of the town.
