Galápagos tortoises) are an archipelagoof volcanic islands distributed around the equator, 972 km west of continental Ecuadorin the Pacific Oceancoord|0|40|S|90|33|W|scale:1400000|display=title.
The Galápagos archipelago has a population of around 40,000, is a province of
Ecuador, a country in northwestern South America, and the islands are all part of Ecuador's national park system. The principal language on the islands is Spanish.
The islands are famed for their vast number of
endemic speciesand the studies by Charles Darwinduring the voyage of the "Beagle" that contributed to the inception of Darwin's theoryof evolutionby natural selection.
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 and also because of the beautiful geography and biodiversity. The first crude navigation chart of the islands was done by the
buccaneer Ambrose Cowleyin 1684. He named the islands after some of his fellow pirates or after the English noblemen who helped the pirates' cause. More recently, the Ecuadorian government gave most of the islands Spanish names. While the Spanish names are official, many users (especially ecological researchers) continue to use the older English names, particularly as those were the names used when Charles Darwinvisited.
"Galapago" is an old Spanish word, meaning saddle. The large Galapagos Tortoises on some of the islands had a shell that resembled an old Spanish saddle, thus the name. The tortoise is a unique animal found only in the Galapagos Islands, yet there are no more than 200 in the 13 main islands.
Located in the eastern
Pacific Oceanat 972 km off the west coast of South America. The closest land mass is the mainland of Ecuadorto the east (the country to which they belong), to the North is Cocos Island720 km and to the South is Easter Islandand San Felix Island at 3200 km.
The islands are found at the coordinates 1°40'N-1°36'S, 89°16'-92°01'W. Straddling the equator, islands in the chain are located in both the northern and southern hemisphere with Volcan Wolf and Volcano Ecuador on Isla Isabela being directly on the equator line. Española the southernmost island and Darwin the northernmost island are spread out over a distance of 220 km.
The Galapagos Archipelago consists of 7880 square km of land over 45,000 square km. The largest of the islands, Isabela, measures 4,588 square km and making up half of the total land area of the Galapagos. Volcan Wolf, on Isabela is the highest point with an elevation of 1,707 m above sea level.The group consists of 13 main islands, 6 smaller islands, and 107 rocks and
islets. The islands are located at the Galapagos Triple Junction. It is also atop the Galapagos hotspot, a place where the earth's crust is being melted from below by a mantle plume, creating volcanoes. The oldest island is thought to have formed between 5 and 10 million years ago. The youngest islands, Isabela and Fernandina, are still being formed, with the most recent volcanic eruptionin May, 2008 when the 5,541-feet- (1,690-metre-) high Cerro Azul mountain started spewing lava after 10 years of inactivity on the island of Isabela.
The main islands of the archipelago (with their English names) shown alphabetically. :
Baltra (South Seymour)
Also known as South Seymour, Baltra is a small flat island located near the center of the Galapagos. It was created by Geological uplift. The island is very arid and vegetation consists of salt bushes, prickly pear cactus and palo santo trees.
During World War 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. The foundations and other remains of the US base can still be seen as you cross the island.
Until 1986, Baltra Airport was the only airport serving the Galápagos. Now there are two airports which receive flights from the continent, the other located on
San Cristóbal Island. Private planes flying to Galapagos must fly to Baltra as it is the only airport with facilities for planes overnight.
Arriving into Baltra all visitors are immediately transported by bus to one of two docks. The first dock is located in a small bay where the boats cruising Galapagos await passengers. The second is a ferry dock which connects Baltra to the island of Santa Cruz.
During the 1940s scientists decided to move 70 of Baltra's Land Iguanas to the neighboring
North Seymour Islandas part of an experiment. This move had unexpected results for during the military occupation of Baltra in World War II, the native iguanas became extinct on the island. During the 1980s iguanas from North Seymour were brought to the Charles Darwin Research Stationas part of a breeding and repopulation project and in the 1990s land iguanas were reintroduced to Baltra. As of 1997 scientists counted 97 iguanas living on Baltra 13 of which were born on the islands.
In 2007 and 2008 the Baltra airport is being remodeled to include additional restaurants, shops and an improved visitor area.
Bartolomé Island is a volcanic islet just off the east coast of Santiago Island in the Galápagos Islands Group. It is one of the "younger" islands in the Galápagos archipelago. It is named after Lieutenant David Bartholomew of the British Navy.
This island is named after Charles Darwin. It has an area of 1.1
square kilometres (0.4 sq mi) and a maximum altitude of 168 metres (551 ft). Here fur seals, frigates, Marine iguanas, Swallow-tailed Gulls, sea lions, whales, marine turtles, Red-footed and Nazca boobies can be seen.
Its name was given in honor of
Spain. It also is known as Hood after an English nobleman. It has an area of 60 square kilometres (23 sq mi) and a maximum altitude of 206 metres (676 ft).
Española is the oldest island at around 3.5 million years and the southernmost in the chain. The island's remote location has a large number of endemic fauna. Secluded from the other islands, wildlife on Española adapted to the island's environment and natural resources. marine iguanas on Española are the only ones that change color during breeding season.
Waved Albatrossis found on the island. 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 has two visitor sites. Gardner Bay is a swimming and snorkeling site as well as offering a great beach. Punta Suarez has migrant, resident, and endemic wildlife including brightly colored
Marine Iguana, Española Lava Lizards, Hood Mockingbirds, Swallow-tailed Gulls, Blue-footed Booby, Red-Footed Boobyand Nazca Boobies, Galápagos Hawks, a selection of Finch, and the Waved Albatross.
The name was given in honor of King Ferdinand II of Aragon, who sponsored the voyage of Columbus. Fernandina has an area of 642 square kilometres (248 sq mi) and a maximum altitude of 1,494 metres (4,902 ft). This is the youngest and westernmost island. In May 13, 2005, a new very eruptive process began on this island when an ash and water vapour cloud rose to a height of 7 kilometers (4.4 mi) and lava flows descended the slopes of the volcano on the way to the sea. Punta Espinosa is a narrow stretch of land where hundreds of Marine Iguanas gather largely on black lava rocks. The famous
Flightless Cormorantinhabits this island and also Galápagos Penguins, Pelicans and Sea Lions are abundant. Different types of lava flows can be compared and the MangroveForests can be observed.
Floreana (Charles or Santa María)
It was named after
Juan José Flores, the first presidentof Ecuador, during whose administration the government of Ecuador took possession of the archipelago. It is also called Santa Maria after one of the caravels of Columbus. It has an area of 173 square kilometres (66.8 sq mi) and a maximum altitude of 640 metres (2,100 ft). It is one of the islands with the most interesting human history and one of the earliest to be inhabited. Pink flamingos 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 officeso that mail could be picked up and delivered to their destination mainly Europeand the United Statesby ships on their way home. At the “Devil's Crown”, an underwater volcanic cone, coralformations are found.
Genovesa Island (Tower)
The name is derived from
Genoa, Italywhere it is said Columbus was born. It has an area of 14 square kilometres (5.4 sq mi) and a maximum altitude of 76 metres (249 ft). 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, frigatebirds, swallow-tailed gulls, which are the only nocturnal of its species in the world can be seen. Red-footed boobies, noddy terns, lava gulls, tropic birds, doves, storm petrels and Darwin finches are also in sight. Prince Philip's Steps is a bird-watching plateauwith Nazca and red-footed boobies. There is a large Palo Santo forest.
This island was named in honor of Queen Isabella. With an area of 4,640 square kilometers (1,792 sq mi), it is the largest island of the Galápagos. Its highest point is Wolf Volcano with an altitude of 1,707 meters (5,600 ft). The island's
seahorseshape is the product of the merging of six large volcanoes into a single landmass. On this island Galápagos Penguins, Flightless Cormorants, Marine Iguanas, pelicans 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.
Named after Fray Antonio Marchena. Has an area of 130 square kilometres (50 sq mi) and a maximum altitude of 343 metres (1,125 ft).
Galápagos hawksand sea lions inhabit this island, and it is home to the Marchena Lava Lizard, an endemic animal.
The small islet is used mostly for
Its name was given after an English nobleman called Lord Hugh Seymour. It has an area of 1.9 square kilometres (0.7 sq mi) and a maximum altitude of 28 metres (92 ft). This island is home to a large population of blue-footed boobies and swallow-tailed gulls. It hosts one of the largest populations of frigate birds. It was formed from geological uplift.
Just north of the Baltra Airport is the small islet of North Seymour. North Seymour was created by seismic uplift rather than being of volcanic origin. The island has a flat profile with cliffs only a few meters from the shoreline, where swallowtail gulls and
tropicbirds sit perched in ledges. A tiny forest of silver-grey Palo santotrees stand just above the landing, usually without leaves, waiting for rain to bring them into bloom. The island is teeming with life. Visiting the island you may have to give way to a passing sea lion or marine iguana. Flocks of pelicans and swallow tailed gulls feed off shore and seasonally masked boobies can also be seen.
North Seymour is an extraordinary place for breeding birds and is home to one of the largest populations of nesting blue-footed boobies and magnificent frigate birds. Pairs of blue-footed boobies can be seen conducting their mating ritual as they offer each other gifts, whistle and honk, stretch their necks towards the sky, spread their wings, and dance--showing off their bright blue feet. Magnificent frigatebirds perch in low bushes, near the boobies, while watching over their large chicks. The frigates are huge, dark acrobats with a convert|90|in|m|sing=on wingspan. Male frigates can puff up their scarlet throat sacks to resemble a giant red balloon. Boobies and frigates have an interesting relationship. Boobies are excellent hunters and fish in flocks. The frigates by comparison are pirates, they dive bomb the boobies to force them to drop their prey. Then the acrobatic frigate swoops down and picks up the food before it hits the water.
Named after the Pinzón brothers, captains of the Pinta and Niña caravels. Has an area of 18 square kilometers (7 sq mi) and a maximum altitude of 458 metres (1,503 ft). Sea lions,
Galápagos hawks, giant tortoises, marine iguanas, and dolphins can be seen here. The Pinta island was home to the last remaining Pinta Tortoise, called Lonesome George. He does not actually live on Pinta Island any longer, he is at a research facility
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 square kilometres (1.9 sq mi) and a maximum altitude of 367 metres (1,204 ft). The high amount of iron contained in the lava at Rábida gives 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.
an Cristóbal (Chatham)
It bears the name of the Patron Saint of seafarers, "
St. Christopher". Its English name was given after William Pitt, 1st Earl of Chatham. It has an area of 558 square kilometres (215 sq mi) and its highest point rises to 730 metres (2395 ft). This islands hosts frigate birds, sea lions, giant tortoises, blue and red footed boobies, tropicbirds, marine iguanas, dolphins, swallow-tailed gulls. Its vegetation includes "Calandrinia galapagos", "Lecocarpus darwinii", and trees such as "Lignum vitae".The largest fresh water lakein the archipelago, Laguna El Junco, is located in the highlands of San Cristóbal. The capital of the province of Galápagos, Puerto Baquerizo Moreno, lies at the southern tip of the island.
anta 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 square kilometres (381 sq mi) and a maximum altitude of 864 metres (2834 ft). Santa Cruz is the island that hosts the largest human population in the archipelago at the town of
Puerto Ayora. The Charles Darwin Research Stationand 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 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
anta Fe (Barrington)
Named after a city in
Spain, has an area of 24 square kilometres (9 sq mi) and a maximum altitude of 259 metres (850 ft). Santa Fe hosts a forestof Opuntia cactus, which are the largest of the archipelago, and Palo Santo. Weathered cliffs provide a haven for swallow-tailed gulls, red-billed tropic birds, shear-waters petrels. Santa Fe species of Galapagos Land Iguanas are often seen, as well as lava lizards.
antiago (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 square kilometers (226 sq mi) and a maximum altitude of 907 metres (2976 ft). Marine iguanas, sea lions, fur seals, land and sea turtles,
flamingos, dolphins and sharks are found here. Pigs and goats, 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.
It is named in honor of a former president of Ecuador, General
Leonidas Plaza. It has an area of 0.13 square kilometers (0.05 sq mi) and a maximum altitude of 23 metres (75 ft). 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.
This island was named after the German geologist
Theodor Wolf. It has an area of 1.3 square kilometres (0.5 sq mi)and a maximum altitude of 253 metres (830 ft). Here fur seals, frigatebirds, masked and red-footed boobies, Marine Iguanas, sharks, whales, dolphins and swallow-tailed gulls can be seen. The most famous resident is the vampire finchwhich feeds on the blood of the boobies and is only found on this island.
A small island directly north of Santa Cruz and directly west of Baltra, this very inaccessible island appears, though unnamed, on Ambrose Cowley's 1684 chart. It is important as the location of multi-decade finch population studies by
Peter and Rosemary Grant.
Although located on the Equator, the
Humboldt Currentbrings cold water to the islands, causing frequent drizzles during most of the year. The weather is periodically influenced by the El Niñophenomenon which brings warmer temperatures and heavy rains.
During the season known as the "Garua" (June to November) the temperature by the sea is 22°C, a steady and cold wind blows from South and Southeast, and frequent drizzles (Garuas) last most of the day, along with dense fog which conceals the islands. During the warm season (December to May) the average sea and air temperature rises to 25°C, there is no wind at all, there are sporadic though strong rains and the sun shines.
Weather changes as altitude increases in the large islands. Temperature decreases gradually with altitude, while precipitation increases due to the condensation of moisture in clouds on the slopes. There is a large variation in precipitation from one place to another, not only with altitude but also depending on the location of the islands, and also with the seasons.
The following table corresponding to the wet 1969 shows the variation of precipitation in different places of Santa Cruz Island:
The precipitation also depends on the geographical location. During March 1969 the precipitation over Charles Darwin Station, on the southern coast of Santa Cruz was 249.0 mm, while on Baltra Island the precipitation during the same month was only 137.6 mm. This is due to the fact that Baltra is located behind Santa Cruz with respect to the prevailing southerly winds, so most of the moisture gets precipitated in the Santa Cruz highlands.
There are significant changes in precipitation from one year to another too. At Charles Darwin Station the precipitation during March 1969 was 249.0 mm, but during March 1970 it was only 1.2 mm.
European discovery of the Galápagos Islands occurred when Dominican
Fray Tomás de Berlanga, the fourth Bishop of Panama, sailed to Peruto settle a dispute between Francisco Pizarroand 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 1952 study by Thor Heyerdahland Arne Skjølsvold, remains of potshards 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 Orteliusand 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 galleons carrying gold and silver from South America to Spain. Alexander Selkirk, whose adventures in Juan Fernández Islandsinspired Daniel Defoeto 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.
Ecuadorannexed 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 FitzRoyto the Galápagos on September 15, 1835to survey approaches to harbors. The captain and others on board including his companion the young naturalist Charles Darwinmade a scientific study of geology and biology on four of the thirteen islands before they left on October 20to continue on their round-the-world expedition. Darwin noticed that mockingbirds differed between islands, though he thought the birds now known as Darwin's fincheswere unrelated to each other and did not bother labelling them by island.cite web |url=http://www.vqronline.org/articles/2006/spring/eldredge-confessions-darwinist/ |title=VQR - Confessions of a Darwinist |accessdate=2007-12-26 |author=Niles Eldredge |authorlink=Niles Eldredge |date= Spring 2006 |publisher=The Virginia Quarterly Review |pages=32–53 ] The governor of the prison colony on "Charles Island" told him that tortoises differed from island to island. Towards the end of the voyage Darwin speculated that the distribution of the mockingbirds and the tortoises might "undermine the stability of Species". [Keynes, Richard ed. 2000. "Charles Darwin's zoology notes & specimen lists from H.M.S. Beagle." Cambridge: Cambridge University Press. [http://darwin-online.org.uk/content/frameset?itemID=F1840&viewtype=text&pageseq=23 June – August 1836] ] When specimens of birds were analysed on his return to Englandit was found that many apparently different kinds of birds were species of finches which were also unique to islands. These facts were crucial in Darwin's development of his theory of natural selectionexplaining evolution, 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, zoologyand herpetology. Another expedition from that Academy was done in 1932 (Templeton Crocker Expedition) to collect insects, fish, shells, fossils, birds and plants.
World War IIEcuador 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 it was suspended in 1959.
Galápagos was made a
provincein Ecuadorby presidential decree by President Guillermo Rodriguez Laraon Feb. 18th, 1973. This decree was amended on March 16th, 1973 to include the Isabela Canton.
The province is coincident with the
Galápagos Islands. The capital is Puerto Baquerizo Moreno. The province is divided in 3 cantons.
San Cristobal Canton with capital in
Puerto Baquerizo Moreno. It has the following parishes: Progreso, with the following precincts: La Soledad, El Socavon, Tres Palos and El Chino, and Santa Maria Island, with the town of Puerto Velasco Ibarra. The following Islands are under the jurisdiction of this Canton: Española, Santa Fe and Genovesa.
Santa Cruz Canton, with capital in
Puerto Ayora. Its has the following parishes: Bellavista, with the precincts El Occidente, El Carmen, Santa Rosa, and Saasaca. Under its jurisdiction are the following Islands: Santiago, Marchena, Pinta, Pinzon, Rabida and Baltra.
Isabela Island, with capital in
Puerto Villamil, and the following parishes: Tomás de Berlanga, with its precincts: Las Merceditas, San Antonio de los Tintos, Cerro Azul and Alemania. Under the jurisdiction of this Canton are the Islands of Fernandina, Wolf and Darwin.
There is a Provincial Judge, as well as Cantonal Judges to in each Canton to deal with misdemeanor cases, as well as Laboral Judges. But for felonies punishable with prison, the province is under the jurisdiction of the Criminal Courts of the Province of Guayas in mainland Ecuador. The causes can be delivered without the use of an attorney. All of the sentences delivered by Provincial and Cantonal Judges can be appealed to the Superior Court of Justice of Guayas Province with seat in Guayaquil.
It is expressely stated that it is the duty of the Provincial authorities to protect the flora and fauna of the Province in coordination with competent organisms and authorities, both national and international.
provinceis in the UTC-6 time zone. The continental part of Ecuadoris in the UTC-5 time zone.
It is one of the few places in the world without an indigenous population. The largest ethnic group is comprised of Ecuadorian
Mestizos, the mixed descendants of Spanish colonists and indigenous Native Americans, who arrived mainly in the last century from the continental part of Ecuador.
In 1959, 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 risen to more than 15,000 people, and 2006 estimates place the population around 40,000 people.
Five of the islands are inhabited: Baltra, Floreana, Isabela, San Cristobal and Santa Cruz.
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,
UNESCOin cooperation with the government of Ecuador sent another expedition to study the conservation situation and choose a site for a research station.
In 1959, the centenary year of
Charles Darwin's publication of " The Origin of Species", the Ecuadorian government declared 97.5% of the archipelago's land area a national park, excepting areas already colonised. The Charles Darwin Foundation(CDF) was founded the same year. The core responsibility of CDF, an international non-governmental organization constituted in Belgium, is to conduct research and provide the research findings to the Government of Ecuador for effective management of Galapagos. CDF´s research efforts work began with the establishment of the Charles Darwin Research Stationon Santa Cruz Island in 1964. During the early years conservation programs, such as eradication of introduced species and protection of native species, were carried out by research station personnel. Now much of that work is accomplished by the Galapagos National ParkService using the research findings and methodolgies developed by CDF.
In 1986 the surrounding 70,000 square kilometres (43,496 sq mi.) of ocean was declared a
marine reserve, second only in size to Australia's Great Barrier Reef. In 1990 the archipelago became a whale sanctuary. In 1978 UNESCOrecognised the islands as a World Heritage Site, and in 1985 a Biosphere Reserve. This was later extended in December 2001 to include the marine reserve.
Noteworthy species include:
Galápagos land iguanas, " Conolophus" spp.
Marine Iguana, "Amblyrhynchus cristatus", the only iguana feeding in the sea
Galápagos tortoise(Galápagos Giant tortoise), "Geochelone elephantopus", known as Galápago in Spanish, it gave the name to the islands
Galápagos Green Turtle, thought to be a subspecies of the Pacific Green Turtle, "Chelonia mydas agassisi"
trepang" sea cucumbers, the cause of environmental battles with fishermen over quotas of this expensive Asian delicacy.
Flightless Cormorant, "Phalacrocorax harrisi"
Great Frigatebirdand Magnificent Frigatebird
Blue-footed Booby, "Sula nebouxii", popular among visitors for their large blue feet which they show off in courtship
Galápagos Penguin, "Spheniscus mendiculus", the only living tropical penguin
Waved Albatross, "Phoebastria irrorata", the only living tropical albatross
Galápagos Hawk, "Buteo galapagoensis", the islands' main scavengerand "environmental police"
* 4 endemic species of
Galápagos Mockingbirds, the first species Darwin noticed to vary from island to island
* 13 endemic species of
buntings, popularly called Darwin's finches. Among them is the Sharp-beaked Ground-finch"Geospiza difficilis septentrionalis" which is sometimes called the "Vampire Finch" for its blood-sucking habits, and the tool-using Woodpecker Finch, "Camarhynchus pallidus"
Galápagos Sea Lions, "Zalophus californianus", closely related to the California Sea Lion, but smaller
plants and animals, such as feral goats, cats, and cattle, brought accidentally or willingly to the islands by humans, represent the main threat to Galápagos. Quick to reproduce, these alien species decimate the habitats of native species. The native animals, lacking natural predators on the islands, are defenseless to introduced species and fall prey.
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 endemic species in the humid zones of San Cristobal, Floreana, Isabela and Santa Cruz. Also, these harmful plants are just a few of introduced species on the Galapagos Islands. There are over 700 introduced plant species today. There are only 500 native and endemic species. This difference is creating a major problem for the islands and the natural species that inhabit them.
Many species were introduced to the Galápagos by
pirates. Thor Heyerdahlquotes 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 Galápagos tortoises and iguanas. Pigs are even more harmful, covering larger areas and destroying the nests of tortoises, turtles and iguanas as well as eating the animals' native food. 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 Galápagos 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. However a recent goat eradication program has cleared most of the goat population from Isabela.
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.
The Galápagos marine sanctuary is under threat from a host of illegal fishing activities, in addition to other problems of development. The most pressing threat to the Marine Reserve comes from local, mainland and foreign fishing targeting marine life illegally within the Reserve, such as sharks (hammerheads and other species) for their fins, and the harvest of sea cucumbers out of season. Development threatens both land and sea species. The growth of both the tourism industry and local populations fuelled by high birth rates and illegal immigration threaten the wildlife of the Archipelago. The recent grounding of the oil tanker "Jessica" and the subsequent oil spill brought this threat to world attention.
Currently, the rapidly growing problems, including tourism and a human population explosion, are further destroying habitats.
