The recent disease events impacting sea stars and other echinoderms along the west coast of North America underscore the importance of having current information about species’ ranges and health. The map below can be used to display current and past distributions and disease status for select sea stars and purple urchins. Data sources include our long-term intertidal monitoring surveys as well as observations from logs submitted by other researchers, divers, and the general public (see acknowledgements below).

Please note that we now have two map display options: 1) display by most recent observation or 2) display by date range. To view all observations for a given site, click on Site Observation History.

Long-term trends in Pisaster ochraceus numbers at our monitored sites can be viewed by location here or by using our Interactive Map & Graphing Tool. Under "Long Term Graph Type" select "species counts data" and under "plot type" select "sea_star".
