Scripps Coastal Reserve provides excellent opportunities to examine the dramatic land-sea interface in Southern California. Commanding a view for 50 kilometers (30 miles), the precipitous upland portion of the reserve, located adjacent to the UC San Diego Scripps Institution of Oceanography (SIO), is topped by a knoll and bounded by steep coastal canyons. The reserve’s rugged coastal bluffs plummet 100 meters (328 feet) to the ocean surface. From there, the marine portion of the reserve plunges to a depth of 227 meters (745 feet) below sea level into the tributaries of the Scripps and La Jolla submarine canyons. Scripps Pier juts 320 meters (1,050 feet) into the Pacific Ocean, providing access to rich, deep, underwater habitats.
Plant and animal communities at the reserve have adapted to the various stresses of life at the marine margin, such as shifting tides, sand migration, inundation, and desiccation. This site’s highly diverse, terrestrial and marine reserve habitats include disturbed coastal sage scrub, succulent scrub, coastal strand, rocky reef, sandy beach, submerged sandy plain, pier pilings, and submarine canyon and associated ledges.
Native American Heritage
Scripps Coastal Reserve has been utilized by the Kumeyaay people since time immemorial, and it continues to be a culturally important site.
The Scripps Coastal Reserve mesa has a history of disturbance, primarily from its use as a military base during World War II and dry-land farming prior to that. Although the mesa continues to be impacted by invasive plant species, 30 years of careful management has restored much of the coastal sage scrub habitat. A vibrant volunteer program continues work to suppress longstanding invasives, eradicate recent arrivals, and re-establish native vegetation.
Each year the Scripps Institution of Oceanography’s Birch Aquarium and local K–12 schools bring hundreds of students to visit reserve tidepools. Volunteer opportunities and docent-led tours of the half-mile trail on the mesa-top are available to the general public. Email firstname.lastname@example.org for the current schedule.
