Species and Habitats

Fidalgo Bay Days seiningSurf smelt eggsFidalgo Bay Aquatic Reserve sign
 
Within Fidalgo Bay Aquatic Reserve you’ll find tidal flats, salt marshes, pocket estuaries, sandy spits and expansive native eelgrass beds— essential habitats for the reproductive, foraging, and rearing success of many fish and bird species.
 
Water birds use the reserve as an important stopover on their migratory routes. Surf smelt, a forage fish species, spawn on the sand and gravel beaches in the bay, and their eggs are often visible among the pebbles along the shoreline. Fidalgo Bay is also one of 21 areas in Puget Sound where Pacific herring, another forage fish species, are known to spawn on submerged vegetation. In addition, Fidalgo Bay is the location of a multi-partner project to restore native Olympia oyster beds in Puget Sound. 

Citizen Science and StewardshipIntertidal Monitoring

A Citizen Stewardship Committee organizes volunteer surveys of forage fish spawning habitat, intertidal species and marine birds at Fidalgo Bay Aquatic Reserve. 
 
The committee also works to educate others about nearshore ecology, the Aquatic Reserve's condition, and planning issues that affect the reserve. For more information on the committee and how to get involved visit aquaticreserves.org.

Preservation and Restoration 

Skagit Land Trust Acquisition and Restoration

The Skagit Land Trust acquired the area south of the railroad trestle in 1999 and, in 2006, some of the area north of the trestle. These lands were then gifted to the state for DNR to manage. The land trust holds a conservation easement on the land to ensure that it is managed primarily to preserve habitat for fish and wildlife. 

West March's Point Restoration 

In 2010, the Skagit River System Cooperative, with help from multiple partners, coordinated a restoration project to restore the beach along March’s Point on the east side of Fidalgo Bay. The goal of the project was to replace lost sediments, rebuild the beach slope and improve habitat for forage fish spawning. Learn more about the project here
