>Map >Satellite This is a relatively undisturbed tidal salt marsh at the north end of Humboldt Bay, with varying exposure of mudflats at low tide.
Salicornia and Distichlis spp. dominate in the upper portions near the mean high-tide line while Zostera marina is dominant in the lower portions. Enteromorpha sp. is common in the raised mudflats during the summer months.
The marsh provides habitat for a number of shore-birds and waterfowl, primarily during migration, with the mudflats providing a variety of molluscs, crustaceans, polychaetes and other invertebrates for food.
The endangered California clapper rail, Rallus longirostris obsoletus, has been reported here.
Integrity: Virtually undisturbed, though the slough is partially confined by levees and is crossed by roads at the upper and lower ends.
Use: Research, educational, hunting
