These data represent the documented intertidal spawning habitat for Pacific sand lance (Ammodytes hexapterus) and Surf smelt (Hypomesus pretiosus), plus the in the shallow subtidal and intertidal spawning habitat of Pacific herring (Clupea pallasii), in western Washington's marine waters. Also displayed are Pacific herring pre-spawner holding areas. Forage fish survey beaches are also displayed. Sand lance, surf smelt and Pacific herring are collectively referred to as forage fish. They are important prey for many species of mammals, birds and fish, including salmon. Sand lance and surf smelt spawn in the upper intertidal zone of beaches comprised of mixed sand and gravel. These fine-grained spawning substrates are susceptible to nearshore development where substrate coarsening may reduce available habitat. Herring deposit their eggs on marine vegetation: eelgrass and various algae, in the shallow subtidal and intertidal zone generally at tidal elevations from +3 feet to -20 feet Mean Low Low Waterline (MLLW). The accurate representation of forage fish spawning habitat and delivery of those data to public sources is necessary for the conservation of these species. Data for this downloadable are updated intermittently; this version was extracted from the system of record to include data through August, 2019. These data require a thorough understanding of the methods of collection to understand how to best by used in an analysis; please contact Phil Dionne or Kirk Krueger prior to using these data in an analysis.
