It drains out across vast mudflats that shimmer bronze and silver in the low light, exposing a feast of invertebrates that draws shorebirds by the tens of thousands. Then the Pacific pushes back in, flooding salt marshes and filling channels, and the bay becomes a different place entirely. This twice-daily transformation is the heartbeat of Willapa National Wildlife Refuge, over 21,000 acres of sand dunes, old-growth forest, tidal marsh, and coastal grassland strung along the shores of what may be the least-known great estuary in the American West. Willapa Bay covers 120 square miles of southwestern Washington, second in size on the Pacific coast only to San Francisco Bay, yet most Americans have never heard of it. That obscurity has been its salvation.

Some of ...

Smooth cordgrass, an Atlantic salt marsh plant likely introduced as packing material in oyster shipments from the East Coast, began colonizing the bay's mudflats in the early 20th century. By the 1990s, the invasion had become ...
