The map includes information from PISCO and MARINe (Multi-agency Rocky Intertidal Network) regular intertidal monitoring surveys as well as information from logs submitted by other researchers, divers, and the general public. Please note that we do not know what is causing Sea Star Wasting Syndrome, and the cause may be different in different regions. This map does not show long-term trends in abundances. 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.
