The Channel Islands (Spanish : islas del Canal, Archipiélago del Norte) are an eight-island archipelago located within the Southern California Bight in the Pacific Ocean, off the coast of California. The four Northern Channel Islands are part of the Transverse Ranges geologic province, and the four Southern Channel Islands are part of the Peninsular Ranges province. Five of the islands are within the Channel Islands National Park, and the waters surrounding these islands make up Channel Islands National Marine Sanctuary. The Nature Conservancy was instrumental in establishing the Channel Islands National Marine Sanctuary. The islands were inhabited as early as 13,000 years ago, the earliest paleontological evidence of humans in North America. They are the easternmost islands in the Pacific Island group.
The Chumash and Tongva Native Americans who lived later on the islands may be the descendants of the original inhabitants, but they were then displaced by Spaniards who used the islands for fishing and agriculture. The U.S. military uses the islands as training grounds, weapons test sites, and as a strategic defensive location. The Channel Islands and the surrounding waters house a diverse ecosystem with many endemic species and subspecies. The islands harbor 150 unique species of plant.
The eight islands are split among the jurisdictions of three California counties: Santa Barbara County (four), Ventura County (two), and Los Angeles County (two). The islands are divided into two groups; the northern Channel Islands and the southern Channel Islands. The four northern Islands used to be a single landmass known as Santa Rosae.
The archipelago extends for 160 miles (257 km) between San Miguel Island in the north and San Clemente Island in the south. Together, the islands’ land area totals 221,331 acres (89,569 ha), or about 346 square miles (900 km2).
Five of the islands (San Miguel, Santa Rosa, Santa Cruz, Anacapa, and Santa Barbara) were made into the Channel Islands National Park in 1980. The Channel Islands National Marine Sanctuary encompasses the waters six nautical miles (11 kilometers; 6.9 miles) off these islands.
Santa Catalina Island is the only one of the eight islands with a significant permanent civilian settlement—the resort city of Avalon, California, and the unincorporated town of Two Harbors. University of Southern California also houses its USC Wrigley Institute for Environmental Studies marine lab in Two Harbors.
The Channel Islands National Park mainland visitor center in Ventura Harbor received 342,000 visitors in 2014. The islands attract around 70,000 tourists a year, mostly during the summer.Visitors can travel to the islands via public boat or airplane transportation. Camping grounds are available on Anacapa, Santa Rosa, Santa Cruz, San Miguel, and Santa Barbara Islands in the Channel Islands National Park. Attractions include whale watching, hikes, snorkeling, kayaking and camping.
Natural seepage of oil occurs at several places in the Santa Barbara Channel.Tar balls or pieces of tar in small numbers are found in the kelp and on the beaches. Native Americans used naturally occurring tar, bitumen, for a variety of purposes which include roofing, waterproofing, paving and some ceremonial purposes.
The Channel Islands at low elevations are virtually frost-free and constitute one of the few such areas in the 48 contiguous US states. It snows only rarely, on higher mountain peaks.

Separated from the California mainland throughout recent geological history, the Channel Islands provide the earliest evidence for human seafaring in the Americas. It is also the site of the discovery of the earliest paleontological evidence of humans in North America.The northern Channel Islands are now known to have been settled by maritime Paleo-Indian peoples at least 13,000 years ago.
The Arlington Springs Man was discovered in 1960 at Arlington Springs on Santa Rosa Island. The remains were dated to 13,000 years BP.
The Tuqan Man was discovered on San Miguel Island in 2005. His remains were exposed by beach erosion, and were preserved by University of Oregon archeologists. His age was determined to be about 10,000 years.
Archeological sites on the island provide a unique and invaluable record of human interaction with Channel Island marine and terrestrial ecosystems from the late Pleistocene to historic times. The Anacapa Island Archeological District is a 700-acre (280 ha) historic district that was listed on the National Register of Historic Places (NRHP) in 1979.
Historically, the northern islands were occupied by the island Chumash, while the southern islands were occupied by the Tongva.
The earliest known Chumash village site is on Santa Rosa Island. It belongs to the period around 7,500 BP. Soon after, the population density on the islands began to rise. Significant increase in fish and marine mammal exploitation has been observed.
Around 2,500 BP (500 BC), there was significant evolution in technology and increasing reliance on fishing. The circular shell fishhooks were increasingly used. Mortars and pestles were manufactured on San Miguel Island for trade with the mainland.
A new type of boat created by the Chumash known as tomol and by the Tongva as te'aats , appeared on the islands around 1,500 BP (500 AD). The boat had become an critical part of Chumash and Tongva culture by 650 AD.
200 – 300 (1800, est.) The Nicoleño were an Uto-Aztecan Native American people who lived on San Nicolas Island in California. The population was "left devastated by a massacre in 1811 by sea otter hunters". The group's last surviving member was given the name Juana Maria, and was born before 1811 and died in 1853. Juana Maria, better known to history as the "Lone Woman of San Nicolas Island" (her native name is unknown), lived alone on San Nicolas Island from 1835 until her removal from the island in 1853, when men discovered her inside a hut made of whalebones and brush. Juana Maria's fondness for green corn, vegetables, and fresh fruit caused severe attacks of dysentery. In her weakness, she fell from Nidever's porch and injured her spine. On Oct. 18, 1853, only seven weeks after arriving on the mainland, she died of dysentery in Garey, California at age 43. Before she died, Father Sanchez baptized and christened her with the Spanish name Juana Maria. She was buried in an unmarked grave on the Nidever family plot at the Santa Barbara Mission cemetery.
Aleut hunters visited the islands to hunt otters in the early 1800s. The Aleuts purportedly clashed with the native Chumash, killing many over trading disputes. Aleut interactions with the natives were detailed in Scott O'Dell's novel Island of the Blue Dolphins which described the indigenous peoples living on the island.
The Chumash and Tongva were removed from the islands in the early 19th century and taken to Spanish missions and pueblos on the adjacent mainland. For a century, the Channel Islands were used primarily for ranching and fishing activities. Several of the islands were used by whalers in the 1930s to hunt for sperm whales.This had significant impacts on island ecosystems, including the local extinction of sea otters, bald eagles, and other species. For example, decline in the local otter population led to population growth of their prey, the black abalone. As a result, the Channel Islands became an important stop in the 1850s for Chinese-American fishermen who harvested the abalone and exported them to Hong Kong.
As most of the Channel Islands are managed by federal agencies or conservation groups, the restoration of the island ecosystems has made significant progress. An example of conservation progress has been the bald eagle, which was threatened due to DDT contamination, but whose populations are now recovering.With the help of scientists from the USC Wrigley Institute for Environmental Studies, the Catalina Island Fox has also recovered from a low of 100 individual foxes to over 1,500 foxes in 2018.
Occasional discussion on the status of the islands has arisen because they (and the Farallon Islands) were not specifically mentioned in the Treaty of Guadalupe Hidalgo which ceded northern Mexico to the United States. Citing these perceived legal ambiguities, in at least two cases settlers created unrecognized Micronations there. A 1944 review by the Mexican government apparently concluded that it had no claim to them, and a 1978 maritime treaty with the U.S. formally closed the issue.
In 1972, in "a bit of political theater", twenty-six Brown Berets sailed to Catalina Island on tourist boats, set up a small encampment near the town of Avalon, put up a Mexican flag and claimed the island on behalf of all Chicanos, citing the Treaty of Guadalupe Hidalgo. Twenty-four days later, sheriff's deputies took everyone back to the mainland.
The United States Navy controls San Nicolas Island and San Clemente Island, and has installations elsewhere in the chain. During World War II all of southern California's Channel Islands were put under military control, including the civilian-populated Santa Catalina where tourism was halted and established residents needed permits to travel to and from the mainland.San Miguel Island was used as a bombing range and Santa Barbara Island as an early warning outpost under the presumed threat of a Japanese attack on California. San Clemente Island was used to train the Navy's first amphibious force to prepare for Pacific combat against the Japanese in World War II. San Nicolas Island has been used since 1957 as a launch pad for research rockets. Santa Rosa Island was used in 1952 as a base for the USAF 669th AC&W Squadron and they operated two Distant Early Warning FPS-10 radars from the hilltops there. In 1955 another FPS-3 search radar was added, and in 1956, a GPS-3 search radar was installed. A new MPS-14 long-range height-finder radar was installed in 1958. The base was shut down in March 1963, when the 669th was moved to Vandenberg AFB near Lompoc, California. The islands still house US Navy SEALs training facilities, including Naval Auxiliary Landing Field San Clemente Island.
The Channel Islands form part of one of the richest marine ecosystems of the world. Many unique species of plants and animals are endemic to the Channel Islands, including fauna such as the Channel Islands spotted skunk, ashy storm-petrel, and flora including a unique subspecies of Torrey pine.
Flora on the Channel Islands include a unique subspecies of pine, oak, and the island tree mallow. Santa Rosa Island holds two groves of the Torrey pine subspecies Pinus torreyana var. insularis, which is endemic to the island. Torrey pines are the United States' rarest pine species.The islands also house many rare and endangered species of plants, including the island barberry, the island rushrose, and the Santa Cruz Island lace pod. Giant kelp forests surround the islands and act as a source of nutrition and protection for other animals.
Invasive species, such as the Australian blue gum tree, olive tree, sweet fennel, and Harding grass, threaten native species through competition for light, nutrients, and water. The Australian blue gum, for example, releases toxins in its leaf litter which prevents other species of plants from growing in the soil surrounding it. The blue gum, as well as other species including the Harding grass, are much more flammable and better adapted to wildfires than native species.Earthworms, thought to have come from mainland topsoil imported for road construction, are altering the unique ecosystem and microbial communities on San Clemente Island, threatening biodiversity. In this formerly earthworm-free region, they change the distribution of plants and vegetation, making it possible for non-native plants to invade.
The Channel Islands and the waters surrounding hold many endemic species of animals, including fauna such as the Channel Islands spotted skunk, island scrub jay, ashy storm-petrel, San Clemente loggerhead shrike, and the San Clemente sage sparrow. Two breeds of livestock, the Santa Cruz sheep and the San Clemente Island goat originate from here. Many species of large marine mammals, including pacific gray whales, blue whales, humpback whales, and California sea lions breed or feed close to the Channel Islands. Current occurrences of the critically endangered North Pacific right whales and historically abundant Steller's sea lions in these areas are unknown. Seabirds, including the western gulls, bald eagles, pigeon guillemots, and Scripps's murrelets use the islands as well for shelter and breeding grounds. The endemic island fox is California's smallest natural canine and has rebounded from its near extinction in the late 1990s. Several endemic reptile and amphibian species including the island fence lizard, island night lizard, and Channel Islands slender salamander live on the islands.Thousands of years ago, pygmy mammoths and short-faced bears could also be found on the islands, despite being extinct today.
Terrestrial conservation efforts are being made to maintain the islands' endemic species. Feral livestock, including pigs, goats, and sheep, pose a threat to many of the species, including the San Clemente loggerhead shrike and Channel Islands spotted skunk. The National Park Service eradicated the feral pigs on Santa Rosa and Santa Cruz islands during the 1990s and on Santa Catalina Island in 2007.Introduced pathogens have devastated island species due to isolation from the mainland. In 1998, an outbreak of canine distemper swept through Santa Catalina Island severely reducing the island skunk and fox populations. Rabies and distemper vaccination programs were initiated to protect the island's wildlife. Canine distemper is thought to have been brought to the islands on a stowaway raccoon or a domestic dog.
In the 1950s, bald eagles and peregrine falcons on the Channel Islands became locally extinct after widespread use of pesticides such as DDT.The birds ingest contaminated fish and seabirds which poisons the adults and weakens their eggs. Golden eagles, which are natural competitors of other birds of prey, do not primarily feed on these animals and were able to colonize the islands in the early 1990s. In the early 2000s, golden eagles were live trapped and relocated. In 2002 and 2006 breeding pairs of bald eagles were reintroduced to the northern islands. Later in 2006, the introduced adult eagles hatched chicks on the islands for the first time since their extinction. The Channel Islands National Park established a bald eagle webcam on their website in 2007.
The California Channel Islands Marine Sanctuary consists of thirteen Marine Protected Areas (MPAs) around the five islands of the Channel Islands National Park. Combined, these smaller thirteen zones are 124,676 acres in size. Eleven of the zones are no-take and harvest areas and the remaining two marine conservation areas allow limited take of lobster and pelagic fish.Although there is a no-take policy, tourists are allowed to visit and observe the beautiful biodiversity. With this, there are several restrictions that limit the type and weight of gear tourists are allowed to bring including transportation–only park/private boats or planes are permitted to enter, fuel transportation, etc. In order to enforce these restrictions and preserve the MPA, the Channel Island National Marine Sanctuary Advisory Council is in charge of state waters including hiring employees and park workers. The federal waters remain under the control and protection of National Oceanic and Atmospheric Administration (NOAA). The California Channel Islands Marine Sanctuary has been moderately successful as shown in a ten year study done by the Partnership for Interdisciplinary Studies of Coastal Oceans (PISCO). From years 2003–2013, the MPA network implemented caused fish species to increase in biomass in terms of both size, numbers, and weight per area. This increase in fish population was seen both in the MPA and as spillover in the regions outside of these thirteen zones. Given the most recent General Management Plan, passed in April 2015, this MPA will continue to be monitored and protected for the next twenty to forty years in hopes of continuing its successful pattern of restoring biodiversity.
The Chumash are a Native American people of the central and southern coastal regions of California, in portions of what is now San Luis Obispo, Santa Barbara, Ventura and Los Angeles counties, extending from Morro Bay in the north to Malibu in the south. Their territory included three of the Channel Islands: Santa Cruz, Santa Rosa, and San Miguel; the smaller island of Anacapa was likely inhabited seasonally due to the lack of a consistent water source.
Anacapa Island is a small volcanic island located about 11 miles (18 km) off the coast of Port Hueneme, California, in Ventura County. The island is composed of a series of narrow islets 6 mi (10 km) long, oriented generally east–west and 5 mi (8 km) east of Santa Cruz Island. The three main islets, East, Middle and West Anacapa, are collectively known as The Anacapas by some authors. All three islets have precipitous cliffs, dropping off steeply into the sea.
Channel Islands National Park consists of five of the eight Channel Islands off the Pacific coast of the U.S. state of California. Although the islands are close to the shore of the densely populated state, they have been relatively undeveloped. The park covers 249,561 acres (100,994 ha), of which 79,019 acres (31,978 ha) are federal land. The Nature Conservancy owns and manages 76% of Santa Cruz Island, the largest of the eight.
The island fox is a small fox that is endemic to six of the eight Channel Islands of California. There are six subspecies, each unique to the island it lives on, reflecting its evolutionary history. They are generally docile, show little fear of humans, and are easily tamed. Island foxes played an important role in the spiritual lives of native Channel Islanders. They have been likely semi-domesticated as pets, used as pelts, or for other functions, like pest control.
Santa Cruz Island is located off the southwestern coast of Ventura, California, United States. It is the largest island in California and largest of the eight islands in the Channel Islands archipelago and Channel Islands National Park. Forming part of the northern group of the Channel Islands, Santa Cruz is 22 miles (35 km) long and 2 to 6 miles wide with an area of 61,764.6 acres (249.952 km2).
Santa Barbara Island is a small island of the Channel Islands archipelago in Southern California. It is protected within Channel Islands National Park, and its marine ecosystem is part of the Channel Islands National Marine Sanctuary.
San Clemente Island is the southernmost of the Channel Islands of California. It is owned and operated by the United States Navy, and is a part of Los Angeles County. It is administered by Naval Base Coronado. It is 21 miles (34 km) long and has 147.13 km2 (56.81 sq mi) of land. The 2018 census estimates 148 military and civilian personnel reside on the island. The city of San Clemente in Orange County, California is named after the island.
San Miguel Island is the westernmost of California's Channel Islands, located across the Santa Barbara Channel in the Pacific Ocean, within Santa Barbara County, California. San Miguel is the sixth-largest of the eight Channel Islands at 9,325 acres (3,774 ha), including offshore islands and rocks. Prince Island, 700 m (2,300 ft) off the northeastern coast, measures 35 acres (14 ha) in area. The island, at its farthest extent, is 8 miles (13 km) long and 3.7 miles (6.0 km) wide.
The Channel Islands National Marine Sanctuary is a sanctuary off the Pacific coast of Southern California. The National Marine Sanctuary program is under the administration of the National Oceanic and Atmospheric Administration.
Santa Rosae was, before the end of the last ice age, an ancient landmass off the coast of present-day southern California, near Santa Barbara County and Ventura County, of which the northern Channel Islands of California are remnants. At its largest, Santa Rosae was roughly 3-4 times bigger than the northern Channel Islands of today, nearly 125 km long from east to west. Between about 20,000 and 5,000 years ago, Santa Rosae lost about 70% of its land mass to post-glacial rising sea level, leaving behind a vast submerged landscape currently being explored by scientists. San Miguel, Santa Rosa, Santa Cruz, and Anacapa Island comprise the unsubmerged portions of Santa Rosae today. This island was about 5 miles offshore. It broke up between about 11,000 and 9,000 years ago, and the present northern Channel Islands took their shape after the continental ice sheets melted and sea levels rose by about 100 meters.
The Santa Barbara Channel is a portion of the Southern California Bight and separates the mainland of California from the northern Channel Islands. It is generally south of the city of Santa Barbara, and west of the Oxnard Plain in Ventura County.
Santa Rosa Island is the second largest of the Channel Islands of California at 53,195 acres. Santa Rosa is located about 26 miles (42 km) off the coast of Santa Barbara, California in Santa Barbara County and is part of Channel Islands National Park.
The island scrub jay, also known as the island jay or Santa Cruz jay, is a bird in the genus, Aphelocoma, which is endemic to Santa Cruz Island off the coast of Southern California. Of the over 500 breeding bird species in the continental U.S. and Canada, it is the only insular endemic landbird species.
The Southern California Bight is a 692-kilometer-long stretch of curved coastline that runs along the west coast of the United States and Mexico, from Point Conception in California to Punta Colonet in Baja California, plus the area of the Pacific Ocean defined by that curve. This includes the Channel Islands of California and the Coronado Islands and Islas de Todo Santos of Baja California.
Anacapa Island Lighthouse is a lighthouse in California, United States, on the entrance to Santa Barbara Channel, California. Constructed in 1912, it was the last major light station built on the west coast. Anacapa and several other islands were collectively designated as Channel Islands National Monument in 1938, though the Coast Guard retained responsibility for the Anacapa lighthouse. Now fully automated and unmanned, the light house still operates, but the National Park Service (NPS) is responsible for Channel Islands National Park.
The wildlife of the Channel Islands of California is wide and diverse, including many endemic species. While the land wildlife is slightly limited, there being only one large, naturally predatory, and native mammal, the small island fox, marine life can include anything from kelp forests to great white sharks.
Humaliwo was a Chumash village located in present-day Malibu, California. “Humaliwo” meant "where the surf sounds loudly". The village occupied a hill across from the lagoon in Malibu Lagoon State Beach.
There are nine national parks located in the state of California managed by the National Park Service. National parks protect significant scenic areas and nature reserves, provide educational programs, community service opportunities, and are an important part of conservation efforts in the United States. There are several other locations inside of California managed by the National Park Service, but carry other designations such as National Monuments. Many of the national parks in California are also part of national forests and National Wildlife Refuges, and contain Native American Heritage Sites and National Monuments.
Tovaangar refers to the Tongva world or homelands. It includes the greater area of the Los Angeles Basin, including the San Gabriel Valley, San Fernando Valley, northern Orange County, parts of San Bernardino County and Riverside County, and the southern Channel Islands, including San Nicholas, Santa Catalina, Santa Barbara, and San Clemente. The homelands of the Chumash are to the northwest, the Tataviam to the north, the Serrano and Cahuilla to the east, and the Acjachemen and Payómkawichum to the south.
