Brown bears in Alaska’s Bristol Bay region spend each year roaming the largely unspoiled land found between the coast and massive mountain-lined national parks and reserves. Standing up to a foot taller than the average human, and weighing as much as a grand piano, these bears are some of the most iconic wildlife species found in America’s great outdoors. In other parts of North America they’re called grizzly bears.
Brown bears are not listed as an endangered species—in fact, some populations are doing quite well—but in Southwest Alaska, they face an impending threat from the proposed development of an open-pit gold and copper mine.
“Bears are large creatures who need large spaces to be able to survive,” said Drew Hamilton, an Alaska-based expedition leader with Natural Habitat Adventures who has spent more than a decade observing and photographing Alaska’s bears.
“The plans for this mine will put up barriers to movement and threaten the primary food source for brown bears—salmon.”
Bristol Bay’s brown bears spend winters hibernating in dens until emerging in springtime to graze on the region’s fresh flowers and plants, along with any appealing dead wildlife found along the way. In the summer season, salmon are a brown bear’s food of choice—and just as favored by consumers who support a $1.5 billion commercial salmon industry.
Building a big mine upstream has real potential to impact everything downstream. And what’s downstream from the proposed Pebble Mine is everything that makes up Bristol Bay. There has been bi-partisan, diverse community-led opposition to the Pebble Mine project for two decades.
Still, developers want to dig a mine one-mile-wide and quarter-mile deep. Carving out Pebble Mine would lead to the destruction of 3,000 acres of wetlands and more than 21 miles of salmon streams. The scar on Alaska’s pristine, productive environment would be visible from space.
“Where the mine plan truly hurts bears is the infrastructure associated with the mine. The proposed road corridor and the power plant would sit squarely in the middle of a route that bears use to move up and down the western shores of Cook Inlet. Development would also get in the way of the route many bears use to get across the mountains as they migrate to match seasonal fish abundance,” says Hamilton. “Any assault on salmon is an assault on bears and Alaskans.“
Bristol Bay boasts the world's largest wild salmon fishery. But what that really means is the region is home to an abundance of biodiversity. In an age of climate change and pressure to develop, it’s vital we protect these wild places.
Locals and visitors regularly spot beluga whales, humpback whales, caribou, brown bears, and moose, not to mention trees, flowers and plants of all types. Pebble Mine exposes the entire biome to a potentially toxic, uncertain future.
The US government put the permitting process on a fast-track, working even during a government shutdown. The administration released a rushed and incomplete draft environmental impact review of the plans, which is now open to public comments and review.
“The time to stop this is now,” Hamilton concluded.
