Please note that we do not know what is causing Sea Star Wasting Syndrome, and the cause may be different in different regions. The map below includes information from our regular intertidal monitoring surveys as well as information from logs submitted by other researchers, divers, and the general public (see acknowledgements below).
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 "pisaster".
