Puget Sound Eelgrass Monitoring Data Viewer

Welcome to the Puget Sound Eelgrass Monitoring Data Viewer - An interactive map that provides access to 16 years of annual eelgrass monitoring data collected between 2000 and 2019 at selected sites in greater Puget Sound.
These data have been collected annually by DNR since 2000 for the purpose of tracking the status of eelgrass in greater Puget Sound as an ecosystem indicator. Underwater video is collected along transects to estimate the abundance of eelgrass at selected sites.
