Washington Marine Vegetation Atlas

More than 200 surveys of seagrasses, kelp and other macroalgae in Washington State

Please send comments to the Nearshore Habitat Program.

What is the Marine Vegetation Atlas?

  • A source of information on current and historical vegetation observations to assist resource managers in protecting and restoring habitat in Puget Sound.  
  • An open-access data catalog to enhance collaborations and science‐based recommendations for resource management, regulatory decisions and marine planning.
  • An easily accessible web‐based interface to enhance public awareness of marine vegetation issues and research.

What are the practical applications of the Atlas?

  • Find the locations of vegetation types of recognized ecological importance and protected by regulations.
  • View, search, and share maps of marine vegetation data. 
  • Download reports and data.
  • Search predefined layers for protected vegetation like seagrass and kelp.  
  • Customize searches for a particular species of interest, survey data, study type, purpose, etc. 
Launch the Atlas in a separate window for full screen or mobile devices.
