Ever wonder how LiMPETS data are used, if data reveal important trends, and how the program informs mangement and conservation efforts? This April, LiMPETS provided state agencies with analyses of the LiMPETS long-term data sets, collected by thousands of student citizen-scientists over a 10+ year period. The report focuses on ecological status and long-term trends along beaches and rocky intertidal areas within California’s North Central Coast region, including trends within California’s new network of marine protected areas. LiMPETS findings identify long-term declines in key species of the rocky intertidal. Additionally, initial benefits of protection may include greater stability of community composition over time.
