(10/26/2011) A study in the Alaskan Arctic, employing camera traps, has shown that oil drilling impacts migrating birds in an unexpected way. The study found that populations of opportunistic predators, which prey on bird eggs or fledglings, may increase in oil drilling areas, putting extra pressure on nesting birds. Predators like fox, ravens, and gulls take advantage of industry infrastructure for nests and dens, moving into areas that may otherwise be inhospitable. In addition, garbage provides sustenance for larger populations of the opportunists.
(03/17/2011) One of the major tenets behind the creation of a national park, or other protected area, is that it will not fade, but remain in essence beyond the pressures of human society, enjoyed by current generations while being preserved for future ones. The protected area is a gift, in a way, handed from one wise generation to the next. However, in the real world, dominated by short-term thinking, government protected areas are not 'inalienable', as Abraham Lincoln dubbed one of the first; but face being shrunk, losing legal protection, or in some cases abolished altogether. A first of its kind study, published in Conservation Letters, recorded 89 instances in 27 countries of protected areas being downsized (shrunk), downgraded (decrease in legal protections), and degazetted (abolished) since 1900. Referred to by the authors as PADDD (protected areas downgraded, downsized, or degazetted), the trend has been little studied despite its large impact on conservation efforts.
(03/07/2011) In Shakespeare's play Macbeth the forest of Birnam Wood fulfills a seemingly impossible prophecy by moving to surround the murderous king (the marching trees are helped, of course, by an army of axe-wielding camouflaged Scots). The Arctic tundra may soon feel much like the doomed Macbeth with an army of trees (and invading species) closing in. In a recent study, researchers found that climate change is likely to push the northern forests of the boreal into the Arctic tundra—a trend that is already being confirmed in Alaska.
(11/23/2010) A thousand square kilometers of the Alaskan tundra burned in September 2007, a single fire that doubled the area burned in the region since 1950. However, a new study in the Journal of Geophysical Research finds that the fire was even more unprecedented than imagined: sediment cores found that it was the most destructive fire in the area for at least 5,000 years and maybe longer. "If such fires occur every 200 years or every 500 years, it's a natural event," University of Illinois plant biology professor Feng Sheng Hu explains in a press release. "But another possibility is that these are truly unprecedented events caused by, say, greenhouse warming."
(11/08/2010) Gulls in northern Alaska are making a killing on the garbage they scavenge from landfills, new research shows. Glaucous gulls that consume a lot of trash raise more chicks than gulls that eat only natural food, according to a study in the August 2010 issue of The Condor. The garbage is a boon for the gulls, but it’s a bust for other birds nesting on Alaska's coastal plain. These gulls are predators, and their burgeoning numbers threaten waterbird populations already in decline.
(07/11/2010) Most of the US's large ecosystems are but shadows of their former selves. The old-growth deciduous forests that once covered nearly all of the east and mid-west continental US are gone, reduced to a few fragmented patches that are still being lost. The tall grassy plains that once stretched further than any eye could see have been almost wholly replaced by agriculture and increasing suburbs. Habitats, from deserts to western forests, are largely carved by roads and under heavy impact from resource exploitation to invasive species. Coastal marine systems, once super abundant, have partially collapsed in many places due to overfishing, as well as pollution and development. Despite this, there are still places in the US where the 'wild' in wilderness remains largely true, and one of those is the Tongass temperate rainforest of Southeast Alaska.
(06/15/2010) A state biologist has labeled a logging proposal to hand over 80,000 acres of the Tongass temperate rainforest to Sealaska, a company with a poor environmental record, 'fatally flawed'. In a letter obtained by mongabay.com, Jack Gustafson, who worked for over 17 years as a biologist with the Alaska Department of Fish and Game, argues that the bill will be destructive both to the environment and local economy.
(04/29/2010) The Tongass temperate rainforest in Alaska is a record-holder: while the oldest and largest National Forest in the United States (spanning nearly 17 million acres), it is even more notably the world's largest temperate rainforest. Yet since the 1960s this unique ecosystem has suffered large-scale clearcutting through US government grants to logging corporations. While the clearcutting has slowed to a trickle since its heyday, a new bill put forward by Senator Lisa Murkowski (Rep.) gives 85,000 acres to Native-owned corporation Sealaska, raising hackles among environmentalists and locals who are dependent on the forests for resources and tourism.
(11/12/2009) A new report states that boreal forests store nearly twice as much carbon as tropical forests per hectare: a fact which researchers say should make the conservation of boreal forests as important as tropical in climate change negotiations. The report from the Canadian Boreal Initiative and the Boreal Songbird Initiative, entitled "The Carbon the World Forgot", estimates that the boreal forest—which survives in massive swathes across Alaska, Canada, Northern Europe, and Russia—stores 22 percent of all carbon on the earth's land surface. According to the study the boreal contains 703 gigatons of carbon, while the world's tropical forests contain 375 gigatons.
(02/06/2009) The North Pacific Fishery Management Council (NPFMC) voted unanimously to close off more than 150,000 square nautical miles of the Arctic sea to commercial fishing. The decision, welcomed by an array of environmentalists and industry groups, is a preventative measure to protect fisheries that have become more accessible as a result of declining sea ice in the Arctic. It is the first time that the federal government has closed a fishery due to climate change instead of over-fishing, says supporters of the ban.
