Court restores federal protections for Yellowstone grizzly bears - Global Warming

Conservationists touted a major victory Tuesday in their battle to protect Yellowstone grizzly bears when a federal appeals court ruled that wildlife managers erred when they removed Endangered Species Act protection from "one of the American West's most iconic wild animals."   The ruling by the U.S. 9th Circuit Court of Appeals struck down the U.S. Fish and Wildlife Service's 2007 decision to remove the bears from the endangered species list. The court cited climate change as having accelerated a beetle infestation that destroys the bears' vital white-bark pine food source, making the grizzly only the second wildlife species, after the polar bear, to earn protection in recognition of harm caused by global warming. The three-judge panel took note of conservationists' warnings that the loss of trees in the upper elevations in and around Yellowstone National Park would probably drive the grizzlies to forage in more populous areas, increasing confrontations between the omnivorous bears and the people and livestock in the lowlands.The appellate panel said the wildlife agency "failed to adequately consider the impacts of global warming and mountain pine beetle infestation on the vitality of the region's white-bark pine trees." The jurists noted that warmer temperatures in recent years had allowed the beetles to survive a seasonal die-off, leaving them to destroy 16% of the trees and damage more than 25%...more
