Rocky intertidal monitoring: 2019?2020 results from Redwood National and State Parks

Monitoring surveys from 2019 to 2020 within Redwood National and State Parks (RNSP) revealed dynamic variations in the rocky intertidal community, including sessile invertebrates, algae, ochre sea star populations, surfgrass, and sea palm. This long-term study, part of the Multi-Agency Rocky Intertidal Network (MARINe), uses permanent plots and transects to track temporal trends, providing critical data for understanding biodiversity changes in this UNESCO World Heritage Site. The program, supported by the National Park Service and UC Santa Cruz, has evolved its reporting format to focus on administrative summaries while retaining comprehensive trend analyses in periodic reports. Key findings highlight ongoing ecological monitoring efforts that contribute to broader spatial and temporal studies of intertidal ecosystems.
