Scripps Coastal Reserve

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 grassy 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 coastal sage scrub, succulent scrub, disturbed grassland, coastal strand, rocky reef, sandy beach, submerged sandy plain, pier pilings, and submarine canyon and associated ledges.

Habitat Restoration

Native prickly-pear and barrel cacti salvaged from nearby developed areas are transplanted onto the reserve to restore succulent-scrub upland habitats.

Public Outreach

Visitors can take self-guided ecological tours along a half-mile biodiversity trail with accompanying brochure; each year the SIO Aquarium and local K-12 schools bring hundreds of students to visit the reserve tidepools.

Field Courses

Site visits by university courses in ecology, oceanography, biology, and geology.
