“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.”
