Saving the Biological Heart of the Arctic
|
|
|
Brooks Yeager, Randall Snodgrass |
This year Congress again will debate a controversial proposal to allow drilling for oil in the Arctic National Wildlife Refuge. The debate has come up periodically since the Reagan Administration first recommended development in 1987. Each time the proposal has been rejected, including a bipartisan vote in the Senate in April 2002. |
|
But even this most recent setback has not deterred drilling proponents. Within hours of the elections in November, the White House and Republican leaders in Congress renewed their calls for drilling in the refuge. The Arctic National Wildlife Refuge is located in remote Northeast Alaska and is approximately 19 million acres in size, an area about the size of South Carolina. The portion of the reserve threatened by oil development is a 100-mile long section of the Arctic Coastal Plain—what government biologists refer to as the "biological heart" of the refuge. The refuge is the only part of Alaska’s northern coastal region or North Slope where Congress specifically prohibits petroleum development. The Arctic refuge is unique in North America. The reserve protects the full spectrum of sub-arctic and arctic plants and animals. Near its southern boundary, taiga forest gives way to the magnificent high peaks of the Brooks Mountain Range. The range and its foothills form a picturesque backdrop for a narrow strip of tundra plain that extends north to the Arctic Ocean. The plain is a critical calving ground, insect relief and summer feeding area for the 129,000-animal Porcupine caribou herd, named after the ice-choked Porcupine River the animals must cross in migrating from their wintering area in Canada’s Yukon Territory. The refuge also provides habitat for many other species such as polar bears, grizzly bears, wolves, wolverines, musk oxen, arctic fox, Dall sheep and 160 species of birds. Alaska’s Arctic Coastal Plain is a region of such high biological significance that scientists at World Wildlife Fund included it among the Global 200 Ecoregions—the 200 most critical ecoregions for biodiversity conservation in the world. Based on seismic exploration in the 1980s, the U.S. Geological Survey estimates the mean economically recoverable oil under the wildlife refuge is 3.2 billion barrels. To put this amount in perspective, Americans consume this much oil every six months. If there is any recoverable oil in the refuge, the government predicts it will take approximately 10 years before it would be available to consumers. In contrast to the Administration’s claim that drilling would require only a “small footprint,” conservationists believe oil exploration and production in the fragile tundra wetlands of the refuge would destroy the area’s wilderness values as well as damage wildlife habitat and displace wildlife species. Government biologists predict that caribou, polar bears and musk oxen would be most impacted by the network of roads, pipelines, and drilling pads and the noise from traffic, aircraft and hundreds of oilfield workers. Gravel mining for roads and drilling pads and siphoning huge volumes of water from rivers and streams to produce oil from wells will have a negative effect on fish and other wildlife. Public opinion polls consistently show a majority of Americans oppose drilling in the Arctic refuge. The surveys also find that people feel strongly that the U.S. should address U.S. energy needs by increasing automobile fuel efficiency and developing renewable energy sources such as wind, solar and geothermal power. A careful energy approach would not only spare the Arctic refuge and other public lands from development, it would address other pressing concerns such as climate change. Even as this debate unfolds, organizations and individuals that are united in defending the Arctic National Wildlife Refuge are working together to protect the refuge as part of the National Wilderness Preservation System. In this way the unique biodiversity of this arctic wilderness can remain a legacy for all Americans, rather than being sacrificed for the lack of a better answer to our nation’s dependency on oil.

In 2003 the laws that authorize federal highway funding, airports and Amtrak are all under re-consideration by Congress. Roads and expansive hardened surfaces, like airport tarmacs, have large-scale environmental impacts, from habitat fragmentation to polluted runoff. A few years ago a study found that no place in the contiguous 48 states was more than 21 miles from a road. Our notion of vast untrammeled American open space is illusory because, in most places, a road runs through it.
To grapple with America’s transportation agenda, smart growth advocates have focused their attention on the Transportation Efficiency Act of 2003, more commonly known as TEA-3. It will fund six years of roads and their alternatives out of the federal gas tax fund. While the White House has not yet given the Congress its proposal for transportation spending over the next 6 years (look for that in early-to-mid April), road building interests are pressing for 1) a higher gas tax, 2) a larger slice from the gas tax fund going for highways, and 3) less environmental review for road building projects. If TEA-3 moves in this direction, it spells trouble for biodiversity.
| Harvard ecologist Richard T.T. Forman and coauthors highlights in the book Road Ecology: Science and Solutions that there is an urgency to take a fresh look at the way roads and life forms interact. Forman assembled an unusual group of academic and government co-authors consisting of nine ecologists, four road transportation experts and one hydrologist |
|
| to address the issues in an interdisciplinary fashion. Here are some of the effects that roads have on nature and humans that good road planning could help mitigate. | |
· Fragmentation. Look at a road as a long, unnatural clearing that changes the way plants and animals move and interact. As the road network fills in it carves habitat into increasingly smaller pieces. The impact on biodiversity is evident. As roads create barriers and fragment habitat, species inbreeding increases and local extinctions occur.
· Invasive species. A road destroys habitats that have evolved over time, but it also creates openings for opportunistic life forms. Unintended “eco-niches” spring up under bridges, along drainage ditches and at the road’s edge.
· Disruption. A road brings significant disruption to the ecosystems it crosses. Animals are affected by traffic disturbance and noise, both of which are functions of traffic volume. Evidence from breeding bird studies suggests that there is a dramatic effect on breeding bird population sizes and species richness near freeways. The effects exist even near lower traffic streets that connect communities.
· Pollution. In addition to noise, roads bring exhaust, oil, road salt, chemicals, and the resultant polluted runoff when it rains. The impact of roads on water quality is particularly damaging. Forman emphasizes that the key issue is mitigating the degredation of water quality from the existing massive road network.
“The road network is, by definition, connected—basically, a large area of connected hard surfaces. Most storm water pipes take the water from the road right to the edge of a lake, stream, or estuary. We have to disconnect the connectivity of the storm water drainage pipe and channel system, so that as much water as possible goes into the soil or wetland. Let the soil and wetland do the filtering before the runoff rejoins surface.” Perforating road corridors for both water and wildlife movement will require new design approaches.
Forman says we need to radically rethink the process of road approval. “There was a Clean Air Act in the ‘70s and it cleaned up America’s air in a substantial way. One of the really interesting components is that, in metro areas, you can’t build a highway without considering its implications on the region’s air quality. Now, that’s an interesting constraint! Why couldn’t we be doing that for biodiversity, hydrology, wildlife migration, and ecosystems for the region? That would be a really important way to get out front—regionally. Road networks, road density and the form of the network are much more important than any one road project.”
Smart Growth America—the national coalition of organizations allied on smart growth—is doing its part to move America’s transportation policy toward more environmentally sustainable ends. Their TEA-3 priorities include road repair rather than new roads and more money available for improving water quality. “Roads have limited life spans,” says SGA policy director Beth Osborne. “Each time a road is reconstructed, there is a chance to make it less harmful to water quality and supply and an opportunity to improve any storm water management systems near that road.”
To protect America’s threatened habitat and the clean water, fresh air and flood protection that healthy ecosystems provide for us, our nation needs to take a new look at our penchant for building more and bigger roads. We need to envision a transportation system that protects health and environmental quality, while serving people’s diverse needs for mobility.

Here are some of the points that Smart Growth America and the Surface Transportation Policy Project urge you to convey to decision makers. · Keep federal gas tax money flowing toward mass transit, planning and environmental mitigation efforts. Because an increased gas tax hike is unlikely in this economy, road building interests are likely to press to move money out of other gas-tax financed programs, such as mass transit infrastructure. Ironically, as more money goes toward pavement, critical planning money that might mitigate its effects on nature may be in short supply. · Check whether your state is using the federal money available for mass transit, planning and mitigation. State officials need to hear your concerns. States may be encouraged to shift money out of environmentally beneficial programs such as the Congestion Mitigation and Air Quality Improvement Program (CMAQ). First incorporated into the 1991 transportation bill, CMAQ funds projects such as public transit improvements, designated bus and carpool lanes, employer-based transportation management plans, limits on vehicle use in downtown areas during periods of peak use and more. · Get involved in the planning process on specific projects and on land use in your area. From community “visioning” projects to zoning decisions, local communities make decisions about transportation systems all the time. Becoming an active voice for sound transportation that is good for people and for the environment can help shape decisions close to home. · Make a personal choice not to sprawl. It’s not just the highways; it’s the people. Personal choices, like opting to live in established areas rather than building in new developments can help keep down the number of exurban roads, private roads and total paved area—all of which degrade habitat.

Global Warming and Biodiversity

Organisms relate to a wide variety of climatic conditions—polar bears need sea ice, many species of cactus need dry environments, Monarch butterflies cannot survive freezing. So it is no surprise that the diversity of living things on earth is likely to be affected by a changing climate. A changing climate is certainly not new in the history of life on Earth, and indeed, the ebb and flow of glaciers |
||
|
has been quite
prominent in recent history. Most kinds of plants and animals (and
presumably micro-organisms although we don’t actually know) appear to
have coped with such changes, moving up slope or down, up latitude or
down, tracking their required conditions. But the current rate of
climate change is rapid and will likely have wide ranging impacts on
biodiversity. One thing that is different today is that landscapes are heavily modified by human activity such that landscapes often are tantamount to obstacle courses to dispersal of species to more favorable sites. That alone is a matter for concern about the ability of many species to survive climate change. If we could create corridors and connections between isolated patches of natural habitat, we might be able to improve the survival chances for many species. Already there are signals in nature of response to the climate change already generated by human activity. Flowers—including Washington’s famous cherry blossoms—are blooming earlier. Migration times are changing too. Ranges of many species of birds and butterflies are shifting up slope (to higher altitudes) or up latitude. In the first issue of Nature this year there were two separate analyses statistically demonstrating that these recorded changes are significant as a broad phenomenon. And it is believed that the first documented extinction from climate change has occurred – the golden toad of Costa Rica’s fabled Monteverde cloud forest—because the cloud base so essential for the forest’s well-being has moved upward. |

The International Convention on Climate Change specifically mentions ecosystems, agriculture and sustainable development as needing protection against “dangerous interference” with the climate system. It appears that biological systems will be the most sensitive of the three to climate change.

The Freshwater
Policy Gap

In recent years we have seen more of the headline-grabbing court cases that read something like: “Obscure Endangered Fish vs. Community Water Supply.” These are almost always the tragic last gasp in struggles that could be avoided if ecological sustainability (and not just one species) was factored into water planning and water policy in the first place. The struggle over the trickle of water that flows through the once vibrant Colorado River basin is an often-cited example of who wins and who loses under water policy in the western U.S., and biodiversity is often on the losing side. |
||
|
However, water
supply isn’t just a western U.S. issue. We’re drinking and
irrigating and using water faster than precipitation can replenish
groundwater from the Great Plains to the Chicago suburbs to the
Everglades. In 2001 and 2002, countless communities in the East
and South struggled to maintain municipal water supplies during the
sustained drought, and changes in weather patterns tell us that old
assumptions about supplies may no longer be reliable. With no
signs of demand dropping, species that depend on wetlands, headwaters,
fast-flowing rivers, clean lakes, estuaries and other freshwater systems
have no guarantees of water for habitat. These are the same systems that
help to purify and store water and to recharge groundwater supplies.
We have few safeguards that will protect the systems that sustain us. |

In one of the Biodiversity Project focus groups on Great Lakes water, when the researcher posed the question, “Who owns the Great Lakes?” one woman paused, pointed her finger skyward and said, “God does.” The response was a reflection, shared by many people, that the natural resources of our world are collective blessings, not commodities. But for water, our legal frameworks don’t mirror her view. The patchwork of American water policy is complex, making strategies for biodiversity protection equally complex. In the West surface water is managed through a system of “prior appropriation.” For the most part, this system gives the first person to use water from a river or stream the legal right to do so forever, regardless of the effect on the river, the environment, or even other water users. The earliest water rights take precedence over all other uses—the first user gets as much as his or her right allows, the next person gets part of what is left, and so on until there is nothing left to distribute. In most eastern states surface water use is based on a riparian system, where property owners who are adjacent to a river or lake have the right to reasonable use of the water. However, they have much more limited discretion over how the water can be used than their western counterparts, because the public collectively owns the surface water. For groundwater, the picture is less clear. Water law developed as common law before hydrology developed as a science, and today the law desperately needs to catch up with the science. Current law does not adequately recognize the connection between surface water and groundwater and the finite nature of aquifers and their water supplies. What is clear is that demand for freshwater resources is rising. With private interests increasingly looking to profit from water supplies, biological systems face even greater threats. This is especially true because water policy is weak and piecemeal when it comes to protecting ecological integrity. The notion that water is a commodity available to the highest bidder is an uncomfortable concept for many Americans. |

Regional models may prove the best approach, responding to regional needs and uses, as well as climate. One promising model is a planned agreement among the eight Great Lakes governors and two Canadian premiers to establish a water management regime for all the waters of the Great Lakes basin. |
When the Perrier Group of North America (a subsidiary of Nestle´ Waters) sought to place high capacity wells in rural Wisconsin, local groups organized to protect river headwaters threatened by the wells. While public sentiment was on their side, they soon found that the laws that regulate permits for high capacity wells aren’t designed to protect living resources like headwaters and wildlife. Perrier pulled out of Wisconsin, but was welcomed with open arms and tax breaks by Michigan, which also lacks regulations that will protect local ecosystems. In both states the Perrier controversy has helped hone a new awareness of the need to develop water resources policy that protects groundwater and biological resources. |

In 1985, U.S. and Canadian officials signed the Great Lakes Charter to improve water stewardship in the region. In June of 2001, the governors and premiers outlined an annex to the Charter—a set of principles or standards by which Great Lakes governments would evaluate new water withdrawal projects. Broadly, “Annex 2001” would provide that anyone proposing to extract Great Lakes basin water must implement strategies to conserve water, must not harm surrounding waters and water resources, and must actually improve aquatic resources (for example by restoring wetlands)—the notion being if you are going to use the system, you have an obligation to improve it. The next steps will be for the governors to agree to the principles, and then each state legislature must pass legislation to make the principles legally binding. The governors had pledged to complete the annex within three years after signing it in principle on June 18, 2001. Unless the process picks up momentum, that goal may slip away. The agreement has the potential to provide the groundwork for an ecosystem model for water management, fulfilling the charge of the 1972 U.S.- Canada Water Quality Agreement to restore and maintain the chemical, physical and biological integrity of the Great Lakes ecosystem. |

Fresh water is essential to all life, and in a world facing predicted water shortages the U.S. and Canada have the opportunity to provide a model for other freshwater systems in both nations and around the globe. Neglecting the biological needs and functions of our freshwater ecosystems is shortsighted folly. The U.S. has the opportunity to be a leader and innovator in shaping sound freshwater policy that is good for people, and great for biodiversity. |
