These data represent the documented intertidal spawning habitat for surf smelt (Hypomesus pretiosus) in western Washington's marine waters. Surf smelt, along with Pacific sand lance (Ammodytes hexapterus) and Pacific herring (Clupea harengus) are collectively referred to as forage fish. They are important prey for many species of mammals, birds and fish, including salmon. 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. The accurate representation of forage fish spawning habitat and delivery of those data to public sources is necessary for the conservation of these species. |
