South La Jolla State Marine Reserve/State Marine Conservation Area

Overview

Located approximately 10 miles north of the City of San Diego, South La Jolla State Marine Reserve (SMR) and South La Jolla State Marine Conservation Area (SMCA) are adjoining marine protected areas (MPAs) that protect an array of habitats.

South La Jolla SMR provides protection for more than five square miles of dense kelp forest, rocky and sandy intertidal areas, and rocky reefs. This MPA’s diverse habitats are home to spawning grunion, garibaldi, giant sea bass, and leopard sharks.

South La Jolla SMCA provides protection for nearly two and a half square miles of sandy seafloor, dense kelp forests, and rocky reefs. These habitats are home to an array of creatures including abalone, yellowtail, brown pelicans, and California sea lions.

With an onshore-offshore orientation, the larger SMR stretches from shore to a depth of 180 feet where it meets the adjacent SMCA. The SMCA extends to the three-nautical-mile state water limit, reaching depths greater than 270 feet. Encompassing a variety of habitats and depths, there are many ways to enjoy the South La Jolla MPAs, including surfing, birdwatching, tidepooling, kayaking, snorkeling, and scuba diving.

About South La Jolla State Marine Reserve/State Marine Conservation Area

Natural History

The area around San Diego once received much more rain than it does now, and large rivers and lagoons were common in ancient times. The combination of these ancient lagoons, rivers, and tectonic activity created the coves, sea cliffs, and canyons of the MPAs we see today. Kelp forests, surfgrass beds, hard and soft sea floor, sandy beaches, and rocky shores exist within these MPAs, creating conditions for high biological diversity.

These environments support a rich assemblage of marine creatures including invertebrates like aggregating anemones, mantis shrimp, and sea stars, and fish such as grunion, barred sand bass, black perch, and garibaldi. It is also common to see sea lions, flocks of brown pelicans, and occasionally migrating gray whales. All seven species of abalone found in California are protected within South La Jolla SMR and SMCA. Along the shore, cliffs provide nooks for roosting seabirds and wave-cut marine terraces provide the occasional harbor seal with a resting place.

For centuries, Native American Tribes in California have relied on marine and coastal resources. Many Native American Tribes in California continue to regularly harvest marine resources within their ancestral territories and maintain relationships with the coast for ongoing customary uses. The Kumeyaay people have a long history of living in the San Diego County area. The tidepools of La Jolla, teeming with edible animals and plants, have been harvested by the Kumeyaay for both food and jewelry for thousands of years. Abundant Native American prehistoric artifacts and human remains have been found along this stretch of coast.

European exploration in Southern California began in 1602 when Sebastian Vizcaino was sent by Spain to map the California coast. Settlement did not begin, however, until 1769 with the Portola Expedition and beginning of the Mission Era. With Spanish settlement, the land was used for cattle ranching, farming, and logging, which transformed the landscape. After the United States acquired California in 1848, homesteading and small communities began to form. A large housing boom in 1880 sparked developers' interest in the bustling port city of San Diego, and La Jolla began to develop into a seaside residential town. Nearby Scripps Institution of Oceanography, one of the oldest marine science research facilities in the United States, remains a hub for cutting-edge marine research. These MPAs are some of the most studied temperate marine systems in the world.

Recreation

In South La Jolla SMR, there is no take of any marine resource permitted. The MPA is easily accessed and provides many recreational opportunities. While the SMCA is offshore and only accessible by boat or kayak, it does offer opportunities for fishing. Recreational anglers are permitted to fish by hook-and-line for pelagic finfish within the South La Jolla SMCA, but no other take is permitted.

Visitors and residents can enjoy surfing, kayaking, scuba diving, snorkeling, tidepooling, and sunbathing. Beginning to intermediate surfers can catch waves at Law Street Beach or Tourmaline, while the more experienced can venture to Big Rock or Bird Rock. Snorkeling and scuba diving can also be rewarding with the right mix of conditions. Low tide exposes tidepools with the best spots being at Sun Gold Point, Bird Rock, and Pacific Beach (False) Point.

Calumet Park, Tourmaline Surfing Park, and Palisades Park offer beautiful views of the MPAs. An expansive sandy beach can be found south of Pacific Beach Point and to the north lie many secluded coves. Many local species living within the La Jolla MPAs can be observed at nearby Birch Aquarium, which is affiliated with the Scripps Institution of Oceanography and open to the public.
