Climate Change Vulnerability Assessment for the California Coastal National Monument: Trinidad and Point Arena-Stornetta Units   [open pdf - 13MB]

From the Introduction: "Climate change can negatively affect rocky shoreline habitats and productivity in several ways. Atmospheric warming is expected to accelerate the current rate of sea-level rise (SLR), inundating many low-lying coastal and intertidal areas, submerging low relief habitats, and posing a threat to important coastal resources. Changing climate also is projected to alter precipitation amounts and timing, air and water temperatures, and overall storm patterns, including more frequent extreme wave events. Many coastal areas are already experiencing early impacts of climate change, including drought, flooding from SLR, and increasing storm intensity and frequency. [...] Vulnerability assessments are an important tool for informing adaptation planning because they consider uncertainty about future climate. Such assessments can help managers and other resource professionals plan and implement actions to lessen climate impacts to important resources such as in rocky shoreline ecosystems. The California Coastal National Monument (CCNM) protects coastline that is nationally recognized for its scenic beauty and diverse array of biological, cultural, and physical resources, including rocky intertidal communities, habitat for seabirds, marine mammals, invertebrates and plant species, and important cultural and historical sites. In this study, we used a vulnerability assessment approach to identify the rocky shoreline features and species that could be the most affected by climate change and SLR within two subunits of the CCNM."
