This report presents the results of the monitoring surveys done in 2011 of the rocky intertidal community at three sites within the Redwood National and State Parks (RNSP) in Del Norte County, California. These sites are part of MARINe (Multi-Agency Rocky Intertidal Network), a regional intertidal monitoring network sponsored by the Bureau of Ocean Energy (BOEM), with additional funding and support from local and state governments, universities, and private organizations (see www.marine.gov). Funding for RNSP sampling is provided by the National Park Service (NPS) through a collaborative agreement with the University of California at Santa Cruz. This monitoring program, adapted from MARINe protocols, was designed to identify and follow temporal trends in populations of the common and/or ecologically important organisms in the rocky intertidal community at three RNSP sites. To accomplish this, sites are sampled twice a year, and data are collected from permanent plots established to monitor changes in sessile invertebrates, algae, and the ochre star (Pisaster ochraceus), and from permanent transects to monitor surfgrass (Phyllospadix spp.). These data are analyzed to determine seasonal and annual changes to the community and will eventually be used to explore broader spatial and temporal trends. The rocky intertidal monitoring program, which was initially started in RNSP in 2004, continues to progress successfully. The procedures for data collection, data management, data analysis, and reporting are working well with no expected revisions to the protocol needed. This report and subsequent annual reports for the intertidal monitoring program are intended primarily as administrative reports. More comprehensive trend analyses of the data will be included in the program’s five-year reports, the first of which will be completed after the 2012 field season.
