Santa Catalina Island (California)
[edit]Santa Catalina Island (Tongva: Pimuu'nga or Pimu; Spanish: Isla Santa Catalina; often shortened to Catalina Island or Catalina) is a rocky island off the coast of Southern California in the Gulf of Santa Catalina. The island covers an area of about 75 square miles (194 square kilometers). It features a diverse and rugged landscape, including rolling hills, canyons, coastal cliffs, and sandy beaches. The island's highest peak is Mount Orizaba, rising to an elevation of 2,097 feet (639 meters). The island is 22 mi (35 km) long and 8 mi (13 km) across at its largest width. The island is situated in the Pacific Ocean, approximately 29 mi (47 km) south-southwest of Long Beach, California. Geologically, Santa Catalina is part of the is the southernmost island of the Channel Islands of California. Politically, Catalina Island is part of Los Angeles County in District 4. Most of the island's land is unincorporated and is thus governed by the county.
Catalina was originally inhabited and used by many different Southern California Tribes, including the Tongva, who called the island Pimuu'nga or Pimu and referred to themselves as Pimugnans or Pimuvit. The first Europeans to arrive on Catalina claimed it for the Spanish Empire. Over the years, territorial claims to the island transferred ownership to Mexico and then the United States of America. During this time, (1920-1922) it was the Prohibition era in the Unite States. The island was sporadically used for smuggling operations involving the illicit transportation of alcohol. The island was also used for otter hunting, and gold-digging, before successfully being developed into a tourist destination in the 1920s. Since the 1970s, most of the island has been administered by the Catalina Island Conservancy.
In 2022 Santa Catalina Island's population was 4,201 people, with a 51.44 percent to 48.56 percent ratio of male to female residents. 90 percent of whom live in the island's only incorporated city, Avalon. The second center of population is the unincorporated village of Two Harbors at the island's isthmus. Development also occurs at the smaller settlements of Rancho Escondido and Middle Ranch. The remaining population is scattered over the island between the two population centers.
Today, the popular tourist destination can be reached via ferry services from mainland California, with the most common departure point being the city of Long Beach. The island also has an airport named, the Catalina Airport in the Sky, which is located on a hilltop and offers spectacular views of the island.
Catalina Island is known for its diverse ecosystems, which include coastal scrub, chaparral, oak woodlands, grasslands, and coastal marine environments. It is also home to various native and introduced species, both on land and in the surrounding waters. Unique species include the island fox and the Catalina Island rattlesnake. The city of Avalon, located on the island's eastern side, is the primary population center and serves as the hub for tourism. Visitors can explore Avalon's streets, visit museums, dine in restaurants, and enjoy various water-based activities such as snorkeling, scuba diving, and boat tours. The island offers opportunities for hiking, biking, camping, and wildlife watching. Catalina Island enjoys a Mediterranean climate, characterized by mild, wet winters and warm, dry summers. The climate makes it an attractive destination year-round, although the summer months tend to be the busiest. Throughout the year, Catalina Island hosts a variety of events and activities, including the Catalina Wine Mixer, the Catalina Island JazzTrax Festival, and many more cultural and outdoor events. Being a tourist drawing area, Catalina's economy is heavily reliant on revenue from it's annual visitors.
History
[edit]Archeological evidence of Native American settlement dates back to 7000 BC. Prior to the modern era, the island was inhabited by the Tongva, who, had the villages, Chowigna (San Pedro) and Guashna (Playa del Rey), regularly traveled back and forth to Catalina for trade. The Tongva had settlements all over the island, with their biggest villages being at the Isthmus and at present-day Avalon, Shark/Little Harbor, and Emerald Bay. They were renowned for their mining, working and the trade of soapstone which was found in great quantities and varieties on the island. This material was in great demand and was traded along the California coast. The island was valued for its natural resources, but was also respected by the Tongva as an important "ceremonial center" with connections to the village of Povuu'nga, located in present-day Long Beach.
The first European to set foot on the island was the explorer Juan Rodríguez Cabrillo, who sailed in the name of the Spanish crown. On October 7, 1542, he claimed the island for Spain and named it San Salvador after his ship. Although his interactions with Catalina Island are not well-documented, his main achievement was in mapping and exploring the coastline, which helped lay the foundation for future European expeditions and settlements in California.
Over half a century later, another Spanish explorer, Sebastián Vizcaíno, arrived at the island on the eve of Saint Catherine's day (November 24) of 1602. Vizcaino renamed the island in the saint's honor. The colonization of California by the Spanish greatly contributed to the decline of the Tongva people because of diseases brought by the Spanish from Europe. By the 1830s, the island's entire native population had been forced to the mainland on the Spanish missions or to work as ranch hands for the many private land owners.
In the late 18th century, the Franciscan friars considered building a mission on Catalina, but abandoned the idea due to the island's rugged terrain, small population size, and lack of fresh water. While Spain maintained its claim on Catalina Island, the Europeans were forbidden to trade with colonies. However, this policy was short lasted as the island lacked the ships to enforce this prohibition; also, much of the colonies wanted to trade with other European powers. During the period stretching from the late 18th to early 19th centuries, Russian hunters from the Aleutian Islands, particularly the Russian-American Company, visited Catalina Island as part of their fur trading expeditions. They were primarily interested in harvesting sea otters for their valuable fur, which led to the decimation of the local sea otter population. The hunting done by the Russian-American's caused a profound ecological impact on the marine life around Catalina Island by depleting a keystone species.
With its numerous hidden coves and relatively low population, the island has been considered a potentially attractive location for pirates and smugglers, much like other coastal areas. While there are historical indications that such activities may have occurred at various times, concrete documented accounts of piracy or significant smuggling operations on the island are limited.
During the 1850s and 1860s, Catalina Island witnessed a minor gold rush, as part of the larger California Gold Rush of that era. Gold miners arrived on the island in search of valuable minerals. However, their scale and success was nothing to be compared to the more prosperous gold rush locations in California. The historical evidence regarding substantial gold deposits on the island remains inconclusive.
In 1846, Governor Pío Pico issued a Mexican land grant, designating the island as Rancho Santa Catalina, and granting it to Thomas M. Robbins. Robbins subsequently established a small ranch on the island. However, in 1850, he sold his interests in Rancho Santa Catalina to José María Covarrubias. A formal claim for this land was submitted to the Public Land Commission in 1853, and in 1867, the grant was officially patented to José María Covarrubias. Covarrubias, in turn, sold the island to Albert Packard of Santa Barbara in 1853. By 1864, the entirety of Catalina Island was under the ownership of James Lick, whose estate maintained control over the island for the following approximately 25 years.
By the end of the 19th century, the island was almost uninhabited except for a few cattle herders. The first owner to try to develop Avalon into a resort destination was George Shatto, a real estate speculator from Grand Rapids, Michigan. Shatto purchased the island for $200,000 (equivalent to $5.4 million in 2021) from the Lick estate at the height of the real estate boom in Southern California in 1887. Shatto created the settlement that would become Avalon, and can be credited with building the town's first hotel, the original Hotel Metropole, and pier. Despite Shatto's efforts, he defaulted on his loan after only a few years and the island went back to the Lick estate. The sons of Phineas Banning bought the island in 1891 from the estate of James Lick. The Banning brothers fulfilled Shatto's dream of making Avalon a resort community with the construction of numerous tourist facilities. On November 29, 1915, a fire burned half of Avalon's buildings, including six hotels and several clubs. In the face of huge debt related to the fire and the subsequent decline in tourism due to World War I, the Banning brothers were forced to sell the island in shares in 1919. On May 10, 1912 Glenn L. Martin flew a homemade seaplane in to Avalon, setting records for distance and time. In 1917 the Meteor Company purchased the Chinese pirate ship Ning Po, the oldest pirate ship afloat, built in 1753, and towed her to the Isthmus of Catalina Island for use as a tourist attraction and restaurant, until destroyed there by fire in 1938.
One of the main investors to purchase shares from the Bannings was chewing-gum magnate William Wrigley, Jr. In 1919, Wrigley bought out nearly every share-holder until he owned controlling interest in the Santa Catalina Island Company. Wrigley invested millions in needed infrastructure and attractions to the island, including the construction of the Catalina Casino which opened on May 29, 1929. Wrigley also sought to bring publicity to the island through events and spectacles. Starting in 1921, the Chicago Cubs, also owned by Wrigley, used the island for the team's spring training. The Cubs continued to use the island for spring training until 1951, except during the war years of 1942 to 1945. Following the death of Wrigley, Jr. in 1932, control of the Santa Catalina Island Company passed down to his son, Philip K. Wrigley, who continued his father's work improving the infrastructure of the island.
During World War II, the island was closed to tourists and used for military training facilities. Catalina's steamships were expropriated for use as troop transports and a number of military camps were established. The U.S. Maritime Service set up a training facility in Avalon, the Coast Guard had training at Two Harbors, the Army Signal Corps maintained a radar station in the interior, the Office of Strategic Services did training at Toyon Bay, and the Navy did underwater demolition training at Emerald Bay.
In 1972, the Brown Berets, a group of Latino activists, Chicanos and Mexican residents occupied Santa Catalina Island, invoking the Treaty of Guadalupe Hidalgo, which has no mention of the islands. On February 15, 1975, Philip Wrigley deeded 42,135 acres (17,051 hectares) of the island from the Santa Catalina Island Company to the Catalina Island Conservancy that he had helped to establish in 1972. This gave the Conservancy control of nearly 90 percent of the island. The balance of the Santa Catalina Island Company that was not deeded to the Conservancy maintains control of much of its resort properties and operations on the island.
Actress Natalie Wood drowned in the waters near the settlement of Two Harbors over the Thanksgiving holiday weekend in 1981 in what was ruled an accidental death. Wood and her husband, Robert Wagner, were vacationing aboard their motor yacht, Splendour, along with their guest, Christopher Walken, and Splendour's captain, Dennis Davern. As a result of statements by Davern, and other factors, Wood's death certificate was altered to indicate the cause was "drowning and other undetermined factors"
In May 2007, the Island Fire was a large wildfire in the island. Largely due to the assistance of 200 Los Angeles County fire fighters transported by U.S. Marine Corps helicopters and U.S Navy hovercraft, only a few structures were destroyed, though 4,750 acres (1,922 hectares) of wildland were burned. In May 2011, another wildfire started near the Isthmus Yacht Club and was fought by 120 firefighters transported by barge from Los Angeles. It was extinguished the next day after burning 117 acres (47 ha). Catalina Island has a notable connection to the world of entertainment. It has been the backdrop for numerous films, including the 1924 silent film "The Thief of Bagdad." It also hosts the annual Catalina Film Festival and was featured in the popular song "26 Miles (Santa Catalina)" by The Four Preps.
Geology
[edit]Catalina Island is a part of the Channel Islands of California, which are a chain of eight islands located in the Pacific Ocean off the coast of Southern California. These islands are often referred to as the Channel Islands archipelago. They are not part of the mainland but are remnants of an ancient mountain range. Catalina is primarily composed of two distinct rock units: Catalina Schist from the Early Cretaceous (95 to 109 million years ago), and Miocene volcanic and intrusive igneous rocks. The geological makeup of Catalina Island is primarily igneous and metamorphic rock. The island is composed of a variety of rock types, including basalt, schist, granite, and limestone. These rocks originated from volcanic eruptions, magma intrusions, and sedimentary deposits over millions of years.
The island is rich in quartz, to the extent that some beaches on the seaward side have silvery-grey sand. These deposits provide insights into the island's history, as they contain fossils of ancient marine life. The island is situated along the boundary of two tectonic plates: the Pacific Plate and the North American Plate. This boundary is marked by the San Andreas Fault and the East Pacific Rise. The islands in this region have been shaped by tectonic uplift and volcanic activity. This means that the Santa Catalina Island land-mass was never directly connected to mainland California. Other geologic factors that contributed to the island topography include further geologic uplift and subsidence, tectonic plate movement, sedimentation, metamorphic activity, weathering, and erosion. The island's landscape is characterized by rugged terrain, including steep cliffs, canyons, and rolling hills. There are also geologic features such as sea caves and marine terraces along the coastline.
Catalina Island has been a site of interest for geologists and researchers studying island geology, as well as the processes of island formation, uplift, and erosion. The island's geology has also contributed to the understanding of tectonic plate interactions in the region. One of the most notable geological features on Catalina Island is the "Catalina Schist." This metamorphic rock is unique to the island and has been studied for its geologic significance. It is believed to be one of the oldest rocks on the island. The geology of Catalina Island is also important for conservation efforts. The Catalina Island Conservancy plays a role in protecting and managing the island's natural resources, including its geological formations.
Flora
[edit]Catalina Island is renowned for its diverse and unique flora, with a wide range of plant communities and species. The island's vegetation is a testament to its rich ecological diversity and history of conservation efforts.
The most common native plant communities of Catalina Island are chaparral, coastal sage scrub, island oak-ironwood woodland, and grassland. These ecosystems are integral to the island's biodiversity and have adapted to its Mediterranean climate and conditions.
Catalina Island is home to approximately 400 species of native plants, each playing a vital role in the island's ecosystem. Among these species, six are considered endemic, meaning they are found only on Catalina Island and nowhere else in the world. These endemics include the Catalina manzanita (Arctostaphylos catalinae); Catalina mahogany (Cercocarpus traskiae); Catalina dudleya (Dudleya hassei); St. Catherine's lace (Eriogonum giganteum var. giganteum); Santa Catalina bedstraw (Galium catalinense ssp. catalinense); and Santa Catalina Island ironwood (Lyonothamnus floribundus ssp. floribundus). Additionally, there's a disjunctive population of toyon var. macrocarpa that is unique to Santa Catalina Island.
The Wrigley Memorial & Botanical Gardens on the island provide an opportunity for visitors to appreciate and learn about these endemic and native plant species. The gardens emphasize the importance of preserving and showcasing the island's exceptional flora.
In addition to native and endemic species, Catalina Island has been impacted by introduced species, which were introduced by human activities. Some of these introduced species, like eucalyptus trees, have become common on the island and can sometimes outcompete native flora. Conservation efforts, led by organizations such as the Catalina Island Conservancy, aim to manage and control invasive species to protect the native ecosystem.
Catalina Island has also been a focal point for botanical research, attracting botanists and researchers who study the island's unique plant species. These studies contribute to our understanding of plant adaptation, island ecology, and conservation.
Fauna
[edit]The island is home to five native land mammals: the island fox, the Spermophilus beecheyi nesioticus subspecies of California ground squirrel, the Santa Catalina Island harvest mouse (Reithrodontomys megalotis catalinae), the Santa Catalina Island deer mouse (Peromyscus maniculatus catalinae), and the ornate shrew (Sorex ornatus). Only one ornate shrew was ever found, from a now-developed spring area above Avalon. Shrews are difficult to capture and may survive in wetter areas of the island.
The Catalina orangetip butterfly is a notable insect on the island. The Southern Pacific rattlesnake (Crotalus oreganus helleri) is also present on the island. This species should not be confused for the Santa Catalina rattlesnake, found on Santa Catalina Island, Mexico.
The Catalina Island bison herd consists of American bison maintained and monitored by the Catalina Island Conservancy. In the 1920s to 1930s, several bison were brought onto Catalina Island for a movie. The bison are popular with the tourists and buildings have painted images of bison and bison weather vanes. Over the decades, the bison herd grew to as many as 600. The population numbered approximately 150 in 2009.
Other non-native animals currently living on the island include the blackbuck, bullfrog, feral cat, mule deer, rat, and common starling. Mule deer were introduced to the island in the 1920s and 30s, and currently have a population density roughly 10 times that of California generally. The island was also previously home to populations of cattle, feral goat, feral pig, and sheep, but these animals are no longer present.
According to the Catalina Island Conservancy, there are 37 resident bird species on the island. Considerably more marine, pelagic, and migrating birds frequent the island, and 127 species have been reported to the Cornell University eBird database from 10 different eBird hotspots. There are several live camera feeds showing bald eagle nests on the island; nests are active February–July.
In the waters surrounding the island, there are schools of fish like Garibaldi, California sheephead, leopard sharks, white seabass, yellowtail, bat rays, giant sea bass, and many more. Great white sharks are also occasionally found or caught off the coast of Catalina, though usually around seal rookeries and not around inhabited areas. Common marine mammals around Catalina include California sea lions and harbor seals.
The Catalina macaw, a type of hybrid parrot, was first bred at Catalina Bird Park in 1940 and is named after Santa Catalina Island.
Grazing & Fire Management
[edit]Grazing practices on Santa Catalina Island have a historical legacy dating back to the late 19th century when ranching operations were established. During this period, livestock, primarily sheep and cattle, were introduced to the island, marking the beginning of a substantial human impact on its ecology.
The introduction of herbivores for grazing had significant ecological consequences for the island. Overgrazing by these introduced animals led to the removal of native vegetation and substantially altered the composition of plant communities. As a result, this overgrazing caused notable changes in the island's ecosystem dynamics, influencing both its flora and fauna.
The ecological effects of grazing practices raised legitimate concerns about habitat degradation and the decline of native plant species on Santa Catalina Island. Conservationists and environmentalists responded by considering management strategies to address the negative impacts of grazing and to protect the island's unique flora. This prompted the implementation of conservation efforts to manage and mitigate the ecological consequences of livestock grazing, with the goal of preserving the island's natural heritage.
Fire is an intrinsic element of the Mediterranean climate in Southern California, and it has played a crucial role in shaping the region's ecosystems over time. Historically, fires occurred infrequently but were a natural part of the landscape. Native plant species have adapted to these fire cycles, and their life histories often depend on periodic burning for regeneration.
Fire Suppression In the 20th century, a shift occurred towards extensive fire suppression efforts. These efforts, while well-intentioned to safeguard property and human life, resulted in the accumulation of vegetation, leading to an increased risk of catastrophic wildfires. The suppression of fire disrupted the natural fire regimes that had shaped the region for millennia and had unintended ecological consequences, including changes in plant composition and fuel load.
Fire Management Contemporary fire management on the island strives to strike a balance between the ecological role of fire and the necessity of protecting human structures and lives. This involves a more nuanced approach that recognizes the importance of fire in maintaining healthy ecosystems. Controlled burns, also known as prescribed fires, are one technique employed to reduce the risk of severe wildfires. These managed fires are intentionally set under controlled conditions to reduce excess vegetation and restore natural fire regimes. Other strategies, such as fuel reduction efforts and public education, are also integral to fire management on Santa Catalina Island. The goal is to protect both human communities and the island's ecological integrity while respecting the historical role of fire in shaping its landscapes.
Climate
[edit]El Niño is a climate pattern characterized by the periodic warming of sea surface temperatures in the Pacific Ocean. Conducted in the vicinity of Santa Catalina Island, a well-established research project was derived to investigate how El Niño events influence the local hydrography and the growth dynamics of giant kelp populations in the area. Data collection involved the measurement of sea surface temperatures, kelp biomass, and other pertinent environmental variables during both El Niño events and non-El Niño periods.
It was concluded that this temperature rise has had diverse effects on the local hydrography, including shifts in water circulation patterns, heightened nutrient available, and alterations in light penetration.
Macrocystis pyrifera, a species of giant kelp, is a pivotal component of the underwater ecosystem of Catalina Island. The study discerned both positive and negative effects of El Niño events on giant kelp The Positive Effects were that El Niño caused an increase in nutrient levels, resulting from shifts in ocean currents, which, in turn, benefited kelp growth in certain areas. The Negative Effects were the warm waters accompanying El Niño which can have detrimental consequences for kelp as the warm water disrupts the normal nutrient-rich upwelling, a process vital for kelp growth.
This study emphasizes the significance of comprehending the dynamic interplay between climate patterns, oceanic conditions, and the growth of pivotal marine species like giant kelp.
