Collected web maps, story maps and downloads produced by the Nearshore Habitat Program - a program within the Aquatic Resources Division of the Washington Department of Natural Resources.

This map service layer shows the seagrass species present at each site sampled (2000-2015) by a monitoring program covering greater Puget Sound. The monitoring is conducted by the Washington Department of Natural Resources. More recent data (2000-2017) is included in the complete dataset that is available for download.

This map service layer contains the site boundary polygons used for monitoring seagrasses in the marine nearshore of greater Puget Sound.  Monitoring is conducted by the Washington Department of Natural Resources. The site polygons cover all the potential native seagrass habitat for the entire monitoring study area.  The underlying data are included in the complete dataset that is available for download.

Eelgrass (Zostera marina) and surfgrass (Phyllospadix spp.) are submerged aquatic plants with recognized ecological value and management protections. This dataset summarizes eelgrass and surfgrass occurrence using data from the ShoreZone Inventory. These seagrasses are classified as being patchy (less than 50%) or continuous (greater than 50%) along each unit of shoreline (an area with similar physical characteristics). The majority of the shoreline is described by line data, polygon features exist in some areas with extensive shallows. The ShoreZone Inventory includes all saltwater shorelines statewide. It was completed between 1994 and 2000 using aerial videography collected at low tide.
