engaging the community to better understand our environment

Forage fish play an important role in local and regional food webs
 as critical prey for juvenile and adult Chinook salmon, seabirds, and marine mammals. Beach spawning forage fish like Pacific sand lance and surf smelt, lay their eggs near the high tide line of sand and gravel beaches, an area that places them at risk from shoreline modifications. A little bit offshore – Pacific herring, another key forage fish and food web component, spawns on submerged aquatic vegetation including eelgrass and kelps. 

Friends has worked over the past two decades to map, protect, and restore San Juan County spawning beaches. In 2019, we ramped up our capacity to cover the winter Pacific sand lance spawning season by training teams of students and community volunteers. 

Our forage fish survey team now consists of Friends staff, 34 volunteers, and schools from 6 different islands. During the 2019/2020 season our field team documented 6 new Pacific Sand Lance spawning beaches as well as 2 previously unknown surf smelt spawning sites. New forage fish spawning sites were found on public and private beaches on Lopez, Orcas, Shaw, San Juan, and Waldron Islands.  

Coupled with survey data from last year (nov 2018-jan 2019) – the first two years of Friends’ 3-year study on Pacific sand lance spawning in the San Juans has more than doubled the number of documented Pacific sand lance spawning beaches in the county from 8 to 19.

Project data is added to the WA Department of Fish and Wildlife’s forage fish statewide spawn habitat maps and informs efforts to protect and restore this essential component of marine food webs.

I have supported the mission of the Friends of the San Juans through the years because it is a citizen-advocacy organization devoted to protecting, preserving, and restoring the natural shorelines and native habitats in the San Juans and surrounding waters through science and education for generations to come.
