“We have sort of an idyllic
estuary”
Willapa Bay, also known as Shoalwater, is the largest estuary between San Francisco and Puget Sound. It boasts one of the least-spoiled environments and the healthiest salmon runs south of Canada, produces one in every four oysters farmed in the United States, and is a favorite pit stop for tens of thousands of migratory birds.
And it’s in trouble.
The infestation of Spartina, imported by accident from the East Coast, collects enough silt to raise the bay floor by up to a foot, turning much of Willapa’s enviably productive tidal zone into a giant, unkempt lawn. At the same time, other introduced plants and animals and two opportunistic species of native shrimp also threaten to spoil the pristine bay.
“If you lose Willapa Bay, it’s of both state and national significance,” says Kim Patten (’83 Ph.D. Horticulture), a Washington State University researcher and associate professor of horticulture who is a leader in the battle for the bay.
“I think it’s a national treasure, because every estuary in North America would try to emulate it. There’s no other estuary out there like it,” Patten says. “We have sort of an idyllic estuary. It’s not perfect, but for all intents and purposes, it’s a very functioning estuary. You don’t get better than that.”
Environmentally, aquatic landscapes from Chesapeake Bay to San Francisco Bay are infamous for what they’ve lost. Willapa Bay’s protectors want to make it renowned for what it kept. They’re starting to get noticed.
Last June, the National Audubon Society ranked Willapa Bay second—just
behind part of Florida’s Everglades—in its Cooling the Hot
Spots report detailing wildlife areas threatened by invasive species. That followed
a similar listing
in the National Wildlife Refuge Association’s 2002 report, Silent
Invasion.
And the Nature Conservancy has made protecting the bay and its rich watershed
one of its highest Washington priorities.
Senator Patty Murray (’72 Recreation) and her colleagues helped secure another $1 million in federal funding for this season’s work, the second in a six-year, multi-partner plan to eradicate Spartina. The state is pitching in hundreds of thousands more.
“It’s so common for us to not realize what we’ve got until we lost it,” says U.S. Representative Brian Baird, D-Vancouver. “This wonderful bay faces some real threats. Spartina, for example, is a nightmare. It can turn the Willapa Bay into the Willapa Prairie.”
