vector digital data
These data represent the documented intertidal spawning habitat for Pacific sand lance (Ammodytes hexapterus) in western Washington's marine waters. Sand lance, along with surf smelt (Hypomesus pretiosus) 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. Sand lance 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.
To document the distribution of intertidal spawning habitat for Pacific sand lance. These data provide guidence for protection and restoration activities.
The majority of these data were collected by WDFW staff with contributions from the North Olympic Salmon Coalition and the Friends of the San Juans.
