These data represent the results of spawning habitat surveys for surf smelt (Hypomesus pretiosus) and Pacific sand lance (Ammodytes hexapterus) conducted by WDFW and others along the marine shorelines of Washington State. Survey results have been summarized as presence or absence (lack of detectable) of spawn for each species and estimated length (parallel to shore) of suitable habitat (beach length). Pacific sand lance and surf smelt, along with Pacific herring (Clupea harengus), are collectively referred to as forage fish and are important prey for marine birds, mammals, and fish, including salmon. Pacific sand lance and surf smelt spawn in the upper intertidal zone of beaches comprised of mixed sand and gravel substrates. 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. These data represent more than 30 years of spawning habitat surveys. |
