Life After a Forest Fire

Forest fires capture a lot of attention and concern. Loggers worry about lost resources.
People who hike and camp in the forest worry they’ll see nothing but ugly, blackened vistas for years
to come. But a big fire this summer in the northwoods gives people a chance to see just
how fast the forest can recover. Even as the fire still burns, foresters see signs of life.
The GLRC’s Stephanie Hemphill reports:


The Cavity Lake fire started in mid-July this summer. It turned out to be the fire people have been
worrying about for seven years. In 1999, huge straight-line winds knocked down millions
of trees. They toppled into an impassable tangle of drying fuel in and near the Boundary
Waters Canoe Area Wilderness in northeastern Minnesota. Locals call it “the
blowdown.”


The Cavity Lake fire gobbled up the blown-down trees. It roared across lakes,
threatening homes and resorts.

Two forest service workers hop in a small boat to document the fire and its aftermath. In
places, the fire seems to have consumed everything, down to the soil, but these two are
looking for life.


Black, powdery ash covers the ground. Burned snags, limbless trees the color of
charcoal, stand against the sky. But even here, biologist Lissa Grover can find signs of
life.


“If you look around, you can see the 20-foot tall trees that took off after the blowdown,
and a lot of them still have cones on the top, and those cones are open now, and the seeds
will fall from them into the bare soil and germinate.”


In fact, some seeds, such as Jack Pine, wait for fire to open:


“There’s a seed bank in the soil, just waiting for a disturbance like this. There’s one plant
called Bicknell’s geranium that sprouts after fire, produces flowers the second year, sets
seed. Those seeds will stay in the soil until the next fire, even if it’s 200 years from now.”


And some plants aren’t waiting for the next generation. Grasses are already pushing
green shoots through the blackened dirt.

Our next stop is a big island. After the 1999 blowdown in northeastern Minnesota, the
Forest Service purposely burned some areas near homes and resorts. The idea was to
reduce the amount of fuel available for wildfires. Crews set this island on fire four years
ago.


Wilderness ranger Tim McKenzie says that intentional burn saved the island, and the
resorts, from the Cavity Lake fire:


“It was traveling pretty good distances and spotting on these islands. As soon as it hit
here it just lay down.”


The blowdown fuel was already burned, and the young trees were too small and green to
keep the fire going.


Animals here are also adapted to fires. Bears, wolves and moose can walk away from a
fire. Birds can fly away or take refuge in the water.


Grover does worry about the young eagles, still in their nests and unable to fly.


“The trees are still there, the nest is still there, the adult eagles are still here, but it’s
unlikely that the juveniles in the nest survived the fire.”


But a few minutes later, we hear a sound that gladdens Grover’s heart: a young eagle
screaming for food.

At least one young eagle survived the Cavity Lake fire.


This land has been swept repeatedly by fires. They start, grow, move, and burn out in a
patchwork pattern. A fire last year burned until it ran into an area that had burned thirty
years ago. And here, in a thirty-year-old burn, is a picture-perfect Boundary Waters
portage.


(Sound of walking)


Young balsams scent the air with their clean, northwoods smell. Young birches lean
across the path. The moss is soft underfoot. The air is moist, and the mosquitoes are
buzzing.


Tim McKenzie fought that fire, thirty years ago. He says whenever fire burns, it’s nature
at work:


“People are used to seeing a snapshot in time. But the landscape that they’re used to
seeing became that landscape because of this process.”


And canoe outfitters here are busy planning routes that will show that landscape changing.

Point: Agreements Will Help Protect Great Lakes

  • The proposed Annex 2001 agreement is the subject of lively debate as to whether it will help or hinder the conservation of the Great Lakes (Photo by Jeremy Lounds)

In 1998, an Ontario company wanted to sell Lake Superior water overseas. Their proposal raised fears that Great Lakes water could be diverted with little oversight. Now, officials from the eight states and two provinces in the region have come up with two proposed agreements that would regulate new water diversion requests.

In 1998 an Ontario company wanted to sell Lake Superior water overseas. Their
proposal raised fears that Great Lakes water could be diverted with little oversight.
Now, officials from the eight states and two provinces in the region have come up with
two proposed agreements that would regulate new water diversion requests. The proposed
agreements are known as the Annex 2001 Implementing Agreements. Great Lakes Radio Consortium
commentator Cameron Davis says the agreements are a good first step in protecting a cherished
resource:


When I was growing up, my family and I used to go to the beach every Sunday. As I stood
looking out over Lake Michigan, I was awed at how it seemed to go on forever. Today I know
better. The Great Lakes are a gift left from the glaciers thousands of years ago. That’s
because less than 1% of Great Lakes water is renewed every year from rainfall, snowmelt,
and groundwater recharge.


Two proposed agreements by the states and provinces would make diversions of Great Lakes water
to places outside of the Great Lakes a virtual impossibility.


The agreements look to be a vast improvement over current laws. First, federal law in the U.S.
allows a diversion only if every Great Lakes Governor approves. That seems like a tough standard
to meet, but in fact, it’s already allowed two diversions of Great Lakes water to take place. In
the 1990’s, diversions were approved to Pleasant Prairie in Wisconsin and another one to Akron,
Ohio. The water was used for municipal supplies.


Second, the proposed agreements are an improvement over the Boundary Waters Treaty – a pact
signed between the U.S. and Canada almost 100 years ago. The treaty doesn’t cover one very
important Great Lake: Lake Michigan. Because Lake Michigan is solely within the U.S. and not
shared with Canada, the treaty leaves the lake unprotected. This is a problem because Lake
Michigan is directly connected to Lake Huron. So water diverted out of Lake Michigan means
water diverted out of Lake Huron.


The agreements are a good first step, but they need to be stronger. For example, they require
regional approval for diversions of water that go outside of the basin of more than one million
gallons per day, but they don’t require regional approval for withdrawals of up to 5 million
gallons per day that stay in the Great Lakes. In addition, the draft agreements need to do a
better job at requiring water conservation before potential water withdrawals can be considered.


We have a choice. We can be against the agreements and keep the status quo or work to make
them even stronger. We need to work to protect our region’s water so that our kids can continue
to look out over the Great Lakes and see them for what they are: vast, magnificent, but fragile
natural treasures.

Wilderness Area to Be Torched

Last summer a violent storm struck down nearly half a million acres of
trees in and around the boundary waters canoe area. The boundary waters
is a pristine wilderness area in northeastern Minnesota. No motorized
vehicles are allowed and the U-S Forest Service does minimal management,
leaving it in its natural state. But now officials are worried about
the fire danger, and they’re planning some measures that normally aren’t
allowed. The Great Lakes Radio Consortium’s Stephanie Hemphill has
