The Galápagos Islands (Spanish name: ''Archipiélago de Colón'' or ''Islas Galápagos'') are an Archipelago made up of 13 main Volcanic Islands , 6 smaller islands, and 107 rocks and islets. The very first island is thought to have formed between 5 and 10 million years ago, as a result of Tectonic activity. The youngest islands, Isabela and Fernandina , are still being formed, with the most recent Volcanic Eruption in 2005. The Galápagos archipelago is politically part of Ecuador , a country in northwestern South America . The islands are distributed around the Equator , 965 kilometres (about 600 miles) west of Ecuador (recently found to have 3 volcanos in the center island, all of them active)(). They are famed for their vast number of Endemic Species and the studies by Charles Darwin that led to his theory of Evolution by Natural Selection . The adjective "Galápagan" may be used to describe things from or related to the islands. CONSERVATION Though the first protective legislation for the Galápagos was enacted in 1934 and supplemented in 1936 , it was not until the late 1950s that positive action was taken to control what was happening to the native flora and fauna. In 1955 , the International Union for the Conservation of Nature organized a fact-finding mission to the Galápagos. Two years later, in 1957 , UNESCO in cooperation with the government of Ecuador sent another expedition to study the conservation situation and to choose a site for a research station. In 1959 , the centenary year of Darwin's publication of ''The Origin of Species'', the Ecuadorean government declared 97.5% of the archipelago's land area a National Park , except areas already colonised. The Charles Darwin Foundation was founded the same year, with its international headquarters in Brussels . Its primary objectives are to ensure the conservation of unique Galápagos ecosystems and promote the scientific studies necessary to fulfil its conservation functions. Conservation work began with the establishment of the Charles Darwin Research Station in 1964 . During the early years, conservation programs, such as eradication of introduced species and protection of native species, were carried out by station personnel. Currently, most resident scientists pursue conservation goals; most visiting scientists' work is oriented towards pure research. When the national park was established, approximately 1,000 to 2,000 people called the islands their home. In 1972 a census was done in the archipelago and a population of 3,488 was recorded. By the 1980s , this number had dramatically risen to more than 15,000 people, and 2006 estimates place the population around 30,000 people. In 1986 the surrounding ocean was declared a Marine Reserve . UNESCO recognised the islands as a World Heritage Site in 1978 , which was extended in December 2001 to include the marine reserve. Noteworthy species include:
THREATS Introduced Plant s and Animal s, which have been brought accidentally or willingly to the islands by humans, represent the main threat to Galápagos. They bring imbalance to the ecosystem of Galápagos by quickly propagating, since they lack natural predators. Some of the most harmful introduced plants are the Guayaba or Guava ''Psidium guajava'', Avocado ''Persea americana'', Cascarilla ''Cinchona pubescens'', Balsa ''Ochroma pyramidale'', Blackberry ''Rubus glaucus'', various Citrus ( Orange , Grapefruit , Lemon ), Floripondio ''Datura arborea'', Higuerilla ''Ricinus communis'' and the Elephant Grass ''Pennisetum purpureum''. These plants have invaded large areas and eliminated the endemic species in the humid zones of San Cristobal, Floreana, Isabela and Santa Cruz. A long list of many animals was introduced to the Galápagos mainly by Pirate s and Buccaneer s. Heyerdahl quotes documents that mention that the Viceroy of Peru , knowing that British pirates ate the goats that they themselves had released in the islands, ordered dogs to be freed there to eliminate the goats. Also, when colonization of Floreana by José de Villamil failed, he ordered that the goats, donkeys, cows, and other animals from the farms in Floreana be transferred to other islands for the purpose of later colonization. Non-native goats, pigs, dogs, rats, cats, mice, sheep, horses, donkeys, cows, poultry, ants, cockroaches, and some parasites inhabit the islands today. Dogs and cats attack the tame birds and destroy nests of birds, land tortoises, and marine turtles. They sometimes kill small galapagos tortoises and iguanas. Pigs are even more harmful, covering larger areas and destroying the nests of tortoises, turtles and iguanas. Pigs also knock down vegetation in their search for roots and insects. This problem abounds in Cerro Azul volcano and Isabela, and in Santiago pigs may be the cause of the disappearance of the land iguanas that were so abundant when Darwin visited. The black rat '' Rattus Rattus '' attacks small galapagos tortoises when they leave the nest, so that in Pinzón they stopped the reproduction for a period of more than 50 years; only adults were found on that island. Also, where the black rat is found, the endemic rat has disappeared. Cows and donkeys eat all the available vegetation and compete with native species for the scarce water. In 1959 , fishermen introduced one male and two female goats to Pinta island; by 1973 the National Park service estimated the population of goats to be over 30,000 individuals. Goats were also introduced to Marchena in 1967 and to Rabida in 1971 . The fast growing poultry industry on the inhabited islands has been cause for concern from local conservationists, who fear that domestic birds could introduce disease into the endemic and wild bird populations. Currently, the rapidly growing problems caused by shark finning, development, tourism, and a human population explosion are further destroying habitats. MAIN ISLANDS The archipelago has been known by many different names, including the "Enchanted Islands" because of the way in which the strong and swift Currents made Navigation difficult. The first crude Navigation Chart of the islands was done by the Buccaneer Ambrose Cowley in 1684 , and in those charts he named the islands after some of his fellow Pirate s or after the English noblemen who helped the pirates' cause. The term "Galapagos" refers to the Spanish name given to the Giant Land Tortoises known to inhabit the islands. The main islands of the archipelago (with their English names) are (alphabetically): Baltra (South Seymour) During WW II Baltra was established as a US Air Force Base. Crews stationed at Baltra patrolled the Pacific for enemy submarines as well as providing protection for the Panama Canal. After the war the facilities were given to the government of Ecuador. Today the island continues as an official Ecuadorian military base. Until 1986, Baltra was the only airport serving the Galapagos. Now one of two airports, most flights operating in and out of Galapagos fly still fly into Baltra. During the 1930's scientists decided to move 70 of Baltra's Land Iguanas to the neighboring island of North Seymour as part of an experiment. This move would prove lucky for scientists. During the American occupation of Baltra, the native iguanas became extinct on the island. During the 1980's iguanas from North Seymour were brought to the Darwin Station as part of a breeding and repopulation project. In the 1990's land iguanas were reintroduced to Baltra and lucky travelers may even see iguanas waiting for them upon their arrival. Bartolomé Named for Lt. David Bartholomew of the British Navy, this small island is located just east of Santiago. Desolate Bartolome is one of the most visited and photographed islands in the Galapagos and served as the backdrop for the movie Master and Commander. Consisting of an extinct volcano and a variety of red, orange, green, and glistening black volcanic formations, the island best known feature is the tuff cone known as Pinnacle Rock. This large black partially eroded lava formation was created when magma expelled from the volcano reached the sea. The seawater cooled the hot lava and caused an explosion. The exploded particles eventually fasted together forming a rock composed of thin layers. Bartlome is an excellent site to see Galápagos Penguins, sea lions, nesting marine turtles, white-tipped reef sharks and a variety of birds. Darwin (Culpepper) This island is named after Charles Darwin. It has an area of 1.1 km&2 and a maximum altitude of 168 metres. Here fur seals, frigates, marine iguanas, swallow-tailed gulls, sea lions, Whales, marine turtles, dolphins, red footed and Nazca boobies can be seen. Española (Hood) Its name was given in honor of Spain . It is also known as Hood after an English nobleman. It has an area of 60 km&2 and a maximum altitude of 206 metres. Española is the oldest and the southernmost island in the chain. Española's remote location helped make it a unique jewel with a large number of endemic Fauna . Secluded from the other islands, wildlife on Española adapted to the island's environment and natural resources. Marine Iguana 's on Española are the only ones that change color during breeding season. Wildlife is the highlight of Española and the star of the show is the Waved Albatross . The island's steep cliffs serve as the perfect runways for these large birds which take off for their ocean feeding grounds near the mainland of Ecuador and Peru. Española's two visitor sites offer an exceptional island visit. Gardner Bay is a favorite destination for swimming and snorkeling as well as offering a great beach. Punta Suarez is one of the highlights of the Galapagos Islands. The variety and quantity of wildlife assures a memorable visit. Visitors find migrant, resident, and endemic wildlife including brightly colored Marine Iguanas , Española Lava Lizards, Hood Mockingbirds, Swallow Tailed Gulls , Blue Footed Boobies and Nazca Boobies , Galapagos Hawks, a selection of Finch, and the Waved Albatross . Fernandina (Narborough) The name was given in honor of King Fernando of Spain, who sponsored the voyage of Columbus. Fernandina has an area of 642 km&2 and a maximum altitude of 1,494 metres. This is the youngest and westernmost island of the Archipelago. In May 13, 2005, a new very eruptive process began on this island when an ash and water vapor cloud rose to a height of 7 kilometers and lava flows descended the slopes of the volcano on their way to the sea. Punta Espinosa is a narrow stretch of land where hundreds of Marine Iguanas gather in large groups on black lava rocks. The famous Flightless Cormorant inhabits this island and also Galapagos Penguin s, Pelican s and Sea Lions are abundant. Different types of Lava Flow s can be compared and the Mangrove Forests can be observed. Floreana (Charles or Santa María) It was named after Juan José Flores , the first President of Ecuador , during whose administration the government of Ecuador took possession of the archipelago. It is also called Santa Maria after one of the Caravel s of Columbus. It has an area of 173 km&2 and a maximum altitude of 640 metres. It is one of the islands with the most interesting human history and one of the earliest to be inhabited. Pink Flamingo s and green sea turtles nest (December to May) in this island. The "patapegada" or Galápagos Petrel is found here, a sea bird which spends most of its life away from land. At Post Office Bay, since the 18th Century Whalers kept a Wooden Barrel that served as Post Office so that mail could be picked up and delivered to their destination mainly Europe and the United States by ships on their way home. At the “Devil´s Crown”, an underwater Volcanic Cone , Coral formations are found. Genovesa Island (Tower) The name is derived from Genoa , Italy where it is said Columbus was born. It has an area of 14 km&2 and a maximum altitude of 76 metres. This island is formed by the remaining edge of a large Crater that is submerged. Its nickname of “the bird island” is clearly justified. At Darwin Bay, Frigatebird s, swallow-tailed gulls, which are the only nocturnal of its species in the world can be seen. Red-footed Boobies , noddy Tern s, lava gulls, tropic birds, Dove s, Storm Petrel s and Darwin Finches are also in sight. Prince Philip´s Steps is a magnificent bird-watching Plateau with Nazca and red-footed boobies. There is a large Palo Santo forest. Isabela (Albemarle) This island was named in honor of Queen Isabela who sponsored the voyage of Columbus. With an area of 4,640 km&2, it is the largest island of the Galápagos. Its highest point is Wolf Volcano with an altitude of 1,707 metres. The island's Seahorse shape is the product of the merging of six large volcanoes into a single landmass. On this island Galápagos Penguin s, Flightless Cormorant s, Marine Iguana s, boobies, Pelican s and Sally Lightfoot Crabs abound. At the skirts and calderas of the volcanos of Isabela, Land Iguanas and Galápagos Tortoises can be observed, as well as Darwin Finches , Galápagos Hawks, Galápagos Doves and very interesting lowland vegetation. The third-largest human settlement of the archipelago, Puerto Villamil, is located at the south-eastern tip of the island. Marchena (Bindloe) Named after Fray Antonio Marchena. Has an area of 130 km&2 and a maximum altitude of 343 metres. Galápagos Hawks and sea lions inhabit this island, and it is home to the Marchena Lava Lizard, an endemic species. North Seymour Its name was given after an English nobleman called Lord Hugh Seymour. It has an area of 1.9 km&2 and a maximum altitude of 28 metres. This islands is home to a large population of blue-footed boobies and swallow-tailed gulls. It hosts one of the largest populations of frigate birds, with their magnificent red pouches. Pinta (Abingdon) It got its name from one of the Caravel s of Columbus. Has an area of 60 km&2 and a maximum altitude of 777 metres. Swallow-tailed gulls, marine iguanas, sparrow hawks, fur seals can be seen here. Also home to the world's rarest living creature, the Pinta giant tortoise. An aged male named Lonesome George is the only survivor. Since there is virtually no hope of finding another specimen, his species is doomed to extinction. Pinzón (Duncan) Named after the Pinzón brothers, captains of the Pinta and Niña caravels. Has an area of 18 km&2 and a maximum altitude of 458 metres. Sea lions, Galápagos Hawk s, giant tortoises, marine iguanas, and dolphins can be seen here. Rábida (Jervis) It bears the name of the convent of Rábida where Columbus left his son during his voyage to the Americas. Has an area of 4.9 km&2 and a maximum altitude of 367 metres. The high amount of iron contained in the lava at Rábida give it a distinctive red color. White-Cheeked Pintail Ducks live in a salt-water lagoon close to the beach, where brown pelicans and boobies have built their nests. Up until recently, flamingos were also found in the salt-water lagoon, but they have since moved on to other islands, likely due to a lack of food on Rábida. Nine species of Finches have been reported in this island. San Cristóbal (Chatham) It bears the name of the Patron Saint of seafarers, " St. Christopher ". Its English name was given after the English nobleman Count Chatham . It has an area of 558 km&2 and its highest point rises to 730 metres. This islands hosts Frigate Birds , Sea Lion s, giant tortoises, Blue and red footed Boobies , tropicbirds, marine Iguana s, Dolphin s, swallow-tailed Gull s. Its vegetation includes ''Calandrinia galapagos'', ''Lecocarpus darwinii'', trees such as ''Lignum vitae'', Matazarno. The largest fresh water Lake in the archipelago, Laguna El Junco, is located in the Highland s of San Cristóbal. The capital of the province of Galapagos, Puerto Baquerizo Moreno , lies at the southern tip of the island. Santa Cruz (Indefatigable) Given the name of the Holy Cross in Spanish, its English name derives from the British vessel HMS ''Indefatigable''). It has an area of 986 km&2 and a maximum altitude of 864 metres. Santa Cruz is the island that hosts the largest human population in the archipelago at the town of Puerto Ayora . The Charles Darwin Research Station and the headquarters of the Galápagos National Park Service are located here. The GNPS and CDRS operate a tortoise breeding center here, where young tortoises are hatched, reared, and prepared to be reintroduced to their natural Habitat . The Highlands of Santa Cruz offer an exuberant vegetation and are famous for the lava tunnels. Large tortoise populations are found here. Black Turtle Cove is a fantastic site surrounded by mangrove which sea turtles, rays and small sharks sometimes use as a mating area. Cerro Dragón, known for its flamingo lagoon, is also located here, and along the trail one may see land iguanas foraging. Santa Fe (Barrington) Named after a city in Spain , has an area of 24 km&2 and a maximum altitude of 259 metres. Santa Fe hosts a Forest of Opuntia Cactus , which are the largest of the archipelago, and Palo Santo. Weathered Cliff s provide a haven for swallow-tailed gulls, red-billed tropic birds, Shear-waters Petrels . Santa Fe species of land iguanas are often seen, as well as Lava Lizard s. There is a picturesque Turquoise Lagoon and calm waters where Snorkeling can be done along with sea lions. Santiago (San Salvador, James) Its name is equivalent to Saint James in English; it is also known as San Salvador, after the first island discovered by Columbus in the Caribbean Sea. This island has an area of 585 km&2 and a maximum altitude of 907 metres. Marine iguanas, sea lions, fur seals, land and sea turtles, Flamingo s, dolphins and sharks are found here. Pig s and Goat s, which were introduced by humans to the islands and have caused great harm to the endemic species, have been eradicated (pigs in 2002; goat eradication is nearing finalization). Darwin Finches and Galápagos Hawks are usually seen as well as a colony of Fur Seals. At Sullivan Bay a recent (around 100 years ago) Pahoehoe Lava Flow can be observed. South Plaza It is named in honor of a former president of Ecuador, General Leonidas Plaza . It has an area of 0.13 km&2 and a maximum altitude of 23 metres. The flora of South Plaza includes Opuntia cactua and Sesuvium plants, which forms a reddish carpet on top of the lava formations. Iguanas (land and marine and some hybrids of both species) are abundant and there are a large number of birds that can be observed from the cliffs at the southern part of the island, including tropic birds and swallow-tailed gulls. Wolf (Wenman) This island was named after the German geologist Theodor Wolf. It has an area of 1.3 km&2 and a maximum altitude of 253 metres. Here fur seals, frigates, masqued and red footed boobies, marine iguanas, sharks, whales, dolphins and swallow-tailed gulls can be seen. The most famous resident is the Vampire Finch which feeds on the blood of the boobies and is only found on this island. HISTORY The European discovery of the Galápagos Islands occurred when Dominican Fray Tomás De Berlanga , the fourth Bishop of Panama , sailed to Peru to settle a dispute between Francisco Pizarro and his lieutenants. De Berlanga's vessel drifted off course when the winds diminished, and his party reached the islands on March 10 , 1535 . According to a 1956 study by Thor Heyerdahl and Arne Skjølsvold, remains of potsherds and other artifacts from several sites on the islands suggest visitation by South American peoples prior to the arrival of the Spanish. The islands first appeared on maps in about 1570 in those drawn by Abraham Ortelius and Mercator . The islands were called "Insulae de los Galopegos" (Islands of the Tortoises). The first English captain to visit the Galápagos Islands was Richard Hawkins , in 1593 . Until the early 19th century, the archipelago was often used as a hideout by mostly English pirates who pilfered Spanish Galleon s carrying gold and silver from South America to Spain. Alexander Selkirk , whose adventures in Juan Fernández Islands inspired Daniel Defoe to write ''Robinson Crusoe'', visited the Galápagos in 1708 after he was picked up from Juan Fernández by the privateer Woodes Rogers. Rogers was refitting his ships in the islands after sacking Guayaquil . The first scientific mission to the Galápagos arrived in 1790 under the leadership of Alessandro Malaspina , a Sicilian captain whose expedition was sponsored by the King of Spain. However, the records of the expedition were lost. In 1793 , James Colnett made a description of the flora and fauna of Galápagos and suggested that the islands could be used as base for the Whalers operating in the Pacific Ocean. He also drew the first accurate navigation charts of the islands. Whalers killed and captured thousands of the Galápagos tortoises to extract their fat. The tortoises could also be kept on board ship as a means of providing of fresh protein as these animals could survive for several months on board without any food or water. The hunting of the tortoises was responsible for greatly diminishing, and in some cases eliminating, certain species. Along with whalers came the fur-seal hunters who brought the population of this animal close to extinction. Ecuador annexed the Galápagos Islands on February 12 , 1832 , naming it Archipelago of Ecuador. This was a new name that added to several names that had been, and are still, used to refer to the archipelago. The first governor of Galápagos, General José de Villamil, brought a group of convicts to populate the island of Floreana and in October 1832 some artisans and farmers joined. The Voyage Of The Beagle brought the survey ship HMS ''Beagle'' under captain Robert FitzRoy to the Galápagos on September 15 , 1835 to survey approaches to harbors. The captain and others on board including his companion the young naturalist Charles Darwin made a scientific study of geology and biology on four of the thirteen islands before they left on October 20 to continue on their round-the-world expedition. The governor of the prison colony on ''Charles Island'' told Darwin that tortoises differed from island to island, and when specimens of birds were analysed on return to England it was found that many different kinds of birds were species of Finch es which were also unique to islands. These facts were crucial in Darwin's development of his Evolution theory, which was presented in '' The Origin Of Species ''. José Valdizán and Manuel Julián Cobos tried a new colonization, beginning the exploitation of a type of lichen found in the islands (Roccella portentosa) used as a coloring agent. After the assassination of Valdizán by some of his workers, Cobos brought from the continent a group of more than a hundred workers to San Cristóbal island and tried his luck at planting sugar cane. He ruled in his plantation with an iron hand which lead to his assassination in 1904. Since 1897 Antonio Gil began another plantation in Isabela island. Over the course of a whole year, from September 1904 , an expedition of the Academy of Sciences of California, led by Rollo Beck, stayed in the Galápagos collecting scientific material on Geology , Entomology , Ornithology , Botany , Zoology and Herpetology . Another expedition from that Academy was done in 1932 (Templeton Crocker Expedition) to collect Insect s, Fish , Shells , Fossil s, birds and plants. During WWII Ecuador authorized the United States to establish a naval base in Baltra island and radar stations in other strategic locations. In 1946 a penal colony was established in Isabela Island, but was suspended in 1959 . Park status The first laws protecting the islands were written into law during 1934 . In 1959 the islands became a national park, and the Galapagos National Park was established in 1968 to preserve the biodiversity. A total of 97% of the land space of the islands was set aside for this purpose, with the remaining 3% for use by people. UNESCO declared the Galápagos Islands a World Heritage Site in 1979 and, six years later, a Biosphere Reserve ( 1985 ), which has resulted in an even greater interest at the international level. In 1990 the archipelago became a whale sanctuary, and in 1998 a marine reserve was created in the surrounding waters, totaling 133,000 km2. The marine reserve became part of the UNESCO National Heritage site in 2001 . SEE ALSO REFERENCES
