Several amazing announcements at the end of last year and the beginning of this year mean big news for the Boundary Waters – specifically, Twin Metals’ request to renew its mineral leases was denied, and a watershed-wide environmental review was initiated. We're proud of our efforts and the great strides we’ve taken to protect the Boundary Waters Wilderness, and we know we couldn't have done it without you or our Campaign partners. You need to know, however, that even though one mining company lost its leases, the fight to protect the Boundary Waters is not over.

More work is ahead for us and for you. There will be critical moments when we will need you to comment on behalf of the Boundary Waters. It is very important that you take action at each opportunity. Right now is one of those times -- comment here!

First, let's back up and break down what happened in December 2016 and the beginning of this year.

What Just Happened?

• On December 14, 2016, the U.S. Forest Service explained it would not agree to the renewal of Twin Metals’ two expired federal mineral leases.
• On December 15, 2016, the U.S. Bureau of Land Management (BLM), which manages federal minerals on the Superior National Forest, informed Twin Metals that the company’s request for renewal of the mineral leases was denied.
• Also on December 15, the U.S. Departments of Agriculture and Interior (parent agencies to the Forest Service and BLM) announced they would bar any new mineral leases or mineral exploration on key lands around the Boundary Waters for two years, to study the Boundary Waters watershed and determine whether it is the wrong place for sulfide-ore copper mining.
• On January 13, 2017, the Forest Service announced the beginning of a 90-day comment period to determine the scope (i.e., what issues should be reviewed) of the environmental review. <- This is an IMPORTANT time for you to chime in and submit a comment. We have one written that you can send as is or edit if you want.
• Also on January 13, the Forest Service announced there will be a public meeting on Thursday evening, March 16, 2017, in Duluth, MN at the Duluth Entertainment and Convention Center. This will be a chance for everyone to raise their voices and help determine the future of the Boundary Waters. We will be asking you all to consider attending. Save the date!

What Does It Mean?
In a nutshell, it means that the Campaign has met our short-term goal and is on track to, but has not yet, achieved our medium-term and long-term goals for protecting the Boundary Waters. Let’s review the Campaign’s short, medium, and long-term goals for protection for the Boundary Waters and its watershed from sulfide-ore copper mining.

• Short Term: Our short-term goal required that Chilean copper mining giant, Antofagasta, and its wholly-owned subsidiary, Twin Metals, be denied the renewal they requested of their expired mineral leases, which are the only federal minerals leases in the watershed of the Boundary Waters. The announcements in December mean that we have accomplished this short-term goal, though the mining companies are challenging the federal agencies’ denial of the lease renewal request. The case is in federal court, and will play out over the next year or two.
• Medium Term: The Campaign’s medium-term goal is a 20-year administrative “withdrawal,” during which no new leases or exploration of federal minerals would occur within the Boundary Waters watershed. The process to create a 20-year withdrawal starts with a two-year pause on new federal mineral activity in the area proposed to be withdrawn, so that federal agencies can do an environmental review of the effects the proposed withdrawal would have on the environment, people, and economy. The announcements from earlier this month have triggered a two-year pause and environmental review, and started the process that should lead to our medium-term goal of a 20-year withdrawal of federal minerals in the watershed of the Boundary Waters.
• Long Term: After the environmental review is done, it will be up to the new Secretary of the Interior Department to decide whether to announce a 20-year withdrawal for the Boundary Waters watershed. If that happens, then we’ll use those years to build support for the Campaign’s ultimate goal: passage by Congress of an act granting permanent withdrawal of federal minerals within the watershed of the Boundary Waters.

To get the best environmental review possible, your comments on this environmental review are needed now! Your engagement in the environmental review process, and your continued support for the Campaign, are critical. The environmental review process has started with a 90-day public comment period. As someone who loves the Boundary Waters, your comment should be sent in as soon as possible, and definitely before April 19. You should also consider attending and speaking up at an agency-hosted public meeting.

So yes, we’ve seen some great forward steps taken in the last several weeks, but we’re not there yet. Luckily, we have a plan for how to get from here to our long-term goal: permanent protection for the Boundary Waters and its watershed ...  And luckily, we have you. Our citizen members, volunteers, and partner organizations are essential. We have only gotten to this stage, and we will only achieve the greater victory of permanent protection, with your continued involvement and support. So please sign and share the petition to keep this momentum moving forward. Thank you!

Recently, we shared a Science Desk blog about landscape ecology, which considers broad patterns of ecological relationships and processes that can never be corralled by boundaries on a map. Its principles support the eagle-eyed perspective we need to protect the Boundary Waters. Water flowing into the Boundary Waters has a huge influence on wilderness water quality and everything that depends on it, so we think in terms of entire watersheds when we consider proposals to undertake sulfide-ore copper mining here.

Thanks to science reports we've commissioned and reports in the media, we know a lot about the flow of ground and surface waters within the Rainy River watershed. We can clearly see how contaminants could be transported from mining locations into the wilderness and beyond by Spruce and Stoney Creeks and associated flowages, the Kawishiwi and Rainy Rivers, and points west and north.

What happens within our airsheds also demands the broad perspectives of landscape ecologists and wilderness advocates. Vast rivers of birds flow across oceans and continents, following flyways that connect wintering grounds with distant breeding habitat – which for many is the Boundary Waters and surrounding wildlands. The air currents that carry these great migrations would be polluted by sulfide-ore copper mining as surely as the rivers beneath.

Sometimes we get an inkling of that airy river when we hear the soft twittering of birds flying in starlight all through the night. Radar that can track migrating birds and reveal the magnitude of the great migrations has helped create the concept of flyways as rivers. That metaphor was embedded in my mind by an encounter with warblers on a cool and misty day in mid May several years ago.

I was planting trees on a campsite on Alton Lake. Across the lake, the treetops, just beginning to leaf out, were vibrant green pillows scattered across the pale landscape. A few yellow-rumped warblers preyed on a hatch of soft little flies.

By late morning the just-hatched insects covered every rock, tree, and shrub near the lake, and suddenly I realized there were warblers everywhere. Along the shore from the south came dozens, then hundreds, all on the prowl, plucking flies from every surface.  There were gorgeous redstarts, strikingly handsome black-throated greens, bay-breasteds resplendent with velvety brown heads and rich chestnut throats. Rusty-cheeked Cape Mays searched a young fir beside me while palms worked the ground practically at my feet.  By noon I’d seen more than half of the 24 species of wood warbler that nest in the BWCAW, and they were there by the thousands.

They piled up against the shore where a bay blocked their flow, until the point was alive with beautiful warblers from forest floor to canopy. Then they surged out across the bay and flew northward, pushed on by warblers pouring in from the south.

I later found that friends at Tettagouche State Park and in Grand Marais, and my husband on Knife Lake were witness that day to the same spectacle, so the crest of this wave of warblers must have been at least 40 miles wide.

Bud Heinselman, in his classic book The Boundary Waters Ecosystem, reports astonishing numbers of warblers in the Boundary Waters and surrounding wildlands. His estimates, based on studies done in the 1970s–80s, range from 1,300–2,200 pairs per square mile - which adds up to some 5 million adults and young wilderness-hatched warblers at the start of the fall migration.

Every one of these warblers preys on insects. One pair can pick off all the caterpillars from a million leaves in the 10 days it takes them to fledge their young. Even though each warbler is tiny (most weigh well under an ounce) together they provide invaluable free (and pesticide-free) insect control services throughout their nesting habitat and on down the flyway. We know about many of the hugely beneficial ways warblers interact with their environment.  For example, Tennessee, Cape May, bay-breasted, and blackburnian warblers play a big role in regulating frequency and severity of spruce budworm epidemics. Many others, no doubt, are yet to be discovered.

Chel Anderson and Heidi Fischer discuss the bird-forest relationship that is so crucial to forest health in their book North Shore: A Natural History of Minnesota’s Superior Coast.  Summed up, our forests must have birds, including the all-important warblers, to maintain health and vigor; and for warblers, forests with a diversity of communities of different species and of various ages, including especially mature coniferous forests in unbroken tracts, are absolutely essential. When this relationship fails, results are dire.

These wonderful warblers are in danger from Twin Metals and the other proposed mines. An obvious peril would be the displacement of thousands of birds by the mining operations’ footprints. Nesting habitat lost to new roads, buildings, parking lots, and waste disposal sites could not be replaced, and each year would mean the loss of what should have been that generation’s offspring. 

The operations’ footprints would be irregularly shaped, meaning that new forest fragmentation would be maximized. A study of global changes in forest cover from 2000 to 2012 reveals that we’re losing forest interior three times as fast as loss of overall forest.  While there was a net loss of forest cover about 2 ½ times the size of Texas during that period, it’s the fragmentation that’s the bigger worry. The authors conclude, “Forest area loss alone from 2000 to 2012 underestimates ecological risks from forest fragmentation. In addition to the direct loss of forest, there was a widespread shift of the remaining global forest to a more fragmented condition.” This is bad because some organisms, including some songbirds, must have large stretches of unbroken forest. 

Also, interior (unfragmented) forest can better withstand impacts from things like invasive species and various kinds of pollution. At the edges of forests, and in small fragments of forest – exactly what the mining operation has produced, with its hundreds of test drill sites with access roads widely scattered throughout the forest, and which would continue to be produced should operations proceed - things like variation in soil moisture, nighttime lights and noise, and traffic have a much bigger impact.

Along the edges of the mining operations, 24/7 noise and light pollution would be more than a nuisance to wildlife of many kinds. For example, even seemingly innocuous lights like porch lights and street lamps have been shown to have negative impacts on migrating and nesting songbirds. The dead zone as far as successful nesting for warblers might extend far beyond the actual footprint of mining operations.

The air the birds travel and breath would be contaminated with dust which could carry, to name some of the toxic ingredients, mercury, sulfur, copper, nickel, cobalt, arsenic, lead, and cadmium, as well as asbestos-like fibers and non-toxic, but still unhealthy, particulates. This scary mix wouldn’t just hover above the mine sites. It would become part of the currents of air that stream up toward Ely some days and out across the wilderness and on to the North Shore on others, to be breathed into lungs, scattered across leaves, lakes, soil, caterpillars, canoeists, warbler nests, and your garden and mine. 

The University of Minnesota’s Center for Forest Ecology Director Lee Frelich discusses potential impacts likely to affect the Boundary Waters in his report Forest and Terrestrial Impacts of Mining. According to Dr. Frelich, windblown metallic dust can remain a problem for several decades after mining ceases on copper-nickel mine tailings. Once in the soil, the heavy metals can be taken up by plants and can be further distributed by forest fires. It can contribute to acidification that may lead to mineral deficiencies and slow plant growth. Essential mycorrhizal relationships may be disrupted.  Cumulatively, the overall resiliency of the forest may be diminished.

Two kinds of rivers, aerial and aquatic, intersected this morning in the form of a yellow- rumped warbler bugging above the Temperance River, not far from where it flows out of the Boundary Waters.  He flew in on last night’s front, and now he’s hunting from the top of a young cedar. From his perspective and ours each insect is backlit by golden sunlight. He eyes his prey, darts out and does some fancy maneuvering, makes the catch and flits back to his perch. He throws back his head and sings.

This bird has traveled to habitat that’s uniquely perfect for his springtime needs.  No other place in his entire range has habitat this intact, air and water this free of pollution, insects this abundant. I really wish I could tell him that his kind will always be able to come here and find clean air to fly through and clean water to hunt over.

We’re still in the early days of spring with not much happening in the woods, color-wise, so the bright yellow splashes on his rump and sides are eye-catching in a way you could say are out of proportion to their tiny size.

You might say, too, that our delight in watching one little bird is a little over the top, but I don’t think so – it feels just right, in this beautiful place, to pause and admire a perfect little predator just returned to the northwoods after an epic journey. 

Ellen Hawkins lives near the edge of the Boundary Waters, off the Sawbill Trail. Retired from the Forest Service, she finds that surprise encounters with wildlife of all kinds are still among her most delightful experiences, just as they were during her years as a Wilderness ranger.

On Tuesday, April 19, Secretary of the Interior Sally Jewell made a bold statement. Her speech laid out a vision for the next 100 years of American conservation policy, one that includes modern science and larger scale thinking to help solve our most complex conservation challenges. One line stood out: “What we need is smart planning, on a landscape-level, irrespective of manmade lines on a map.” Secretary Jewell continued to describe what landscape-level planning looks like, and she included Minnesota’s Boundary Waters Canoe Area Wilderness as a prime example of a special place “where science is helping us better understand the value of the land and water and potential impacts of development.” But what does landscape-level planning mean for the Boundary Waters Wilderness?

Landscape-level planning draws on a scientific discipline called landscape ecology. Though Secretary Jewell’s announcement makes it sound like cutting edge science, landscape ecology has a long pedigree and has been a useful tool for conservation scientists and land managers since the 1980s. Now that it is has infiltrated to the highest levels of the public land management agencies, landscape ecology can be used more pervasively to better deal with the large scale conservation problems we face today.

Landscape ecology cuts to the heart of what is difficult about studying the natural environment: spatial scale. Natural scientists must set boundaries on their studies to avoid the overwhelming complexity that is the natural world. Instead of considering all predator-prey interactions in the Superior National Forest, for instance, a Canada lynx biologist might only consider the interaction between lynx and snowshoe hares in a region inhabited by a particular group of lynx. Similarly, an ecologist looking into the history of species composition of the Boundary Waters Wilderness forest must first determine the spatial extent of her study so she does not end up investigating all of Minnesota. The discipline of landscape ecology gives ecologists tools to discuss the impact of spatial scale on the natural patterns and processes that affect the pieces of the environment--from underlying rocks to individual organisms to population size of threatened species.

Landscape ecology also provides an crucial framework and common language to understand the interconnection of different types of land. As Secretary Jewell noted in her speech, today’s United States is a patchwork (ecologists might call it a “mosaic”) of urban, suburban, agricultural, industrial, and more natural lands. Even those more natural lands fall along a spectrum of “wildness” -- from city parks planted with shade trees to the remotest parts of federally designated Wilderness Areas. Landscape ecologists seek to incorporate the whole landscape--patchiness and all--in their efforts to understand the natural and human-caused dynamics that affect places such as the Boundary Waters Wilderness.

Armed with the landscape perspective, an ecologist is no longer limited to focus solely within a Wilderness Area’s boundaries to understand how it functions. Instead, she can think about how large-scale patterns of land use, development, atmospheric pollution, climate change, human visitorship, shifts in vegetation species composition, or wildlife migrations can play dramatic roles in affecting a protected place. In other words, landscape ecology properly acknowledges that no place is an island -- even literal islands.

This why landscape-level planning is crucially important for both the future of American conservation policy and for the Boundary Waters Wilderness. Scientists know so much more in 2016 about watersheds and the interconnectivity of a landscape than they did in 1966 when the Bureau of Land Management first issued mineral leases in the watershed of the Boundary Waters Wilderness. The Boundary Waters Wilderness does not exist in isolation from its surrounding environment. From fluxes of wolves and moose and Canada lynx moving across the Wilderness boundary to water that pours into the Wilderness area from outside of it, the Boundary Waters Wilderness depends on its larger landscape. In order to make the best possible decision, responsible action by the land management agencies requires the consideration of the impacts of proposed sulfide-ore mining at a watershed scale.

That’s why we are working for permanent protection for the Boundary Waters by protecting its watershed. And we need your help to make it happen.

Please tell Minnesota’s Senators Franken and Klobuchar and Representative Nolan that you agree with Secretary Jewell that Boundary Waters Wilderness deserves the best, modern science to be used in decision-making at a landscape scale by taking action here.

The Boundary Waters Canoe Area Wilderness is a breathtaking wild landscape of lakes, streams and woods that covers 1.1 million acres along the Canadian border. International mining companies have proposed building sulfide-ore copper mines right on the edge of the Wilderness, threatening to contaminate its pristine waters and disrupt its quiet wilderness character.

Through the Science Desk series, we try to describe the importance of the Boundary Waters, its watershed and the different ways sulfide-ore copper mining would fundamentally change the landscape. Instead of a written account this month, we invite you to take a virtual tour and see what’s at stake.

This tour uses the Google Earth platform to guide you through the beautiful Boundary Waters in a geographically grounded context. You can see pictures of the South Kawishiwi River and Birch Lake, as well as check out the locations of the sulfide-ore copper mining facilities proposed by Twin Metals Minnesota.
