Conservation
For millions of years the Galapagos Islands went undisturbed by man. Shortly
after their discovery in 1535 visitors began to pillage the island's natural resources.
Tortoises,
whales
and fur seals
were all hunted to near extinction. Plants and animals were introduced to the
islands, which changed the natural balance of life and further endangered the native
species. In the 1930's, with the advent of William Bebe's book Galapagos the World's
End the first laws were passed to protect this area. Unfortunately since there
was no enforcement of the laws they had little effect.
Finally in 1959, the 100th anniversary of the publishing of Charles Darwin's The
Origin of Species, the first real progress in conservation was made. A
non-profit organization dedicated to scientific research and conservation of the islands
was established as the Charles Darwin
Foundation. The government of Ecuador also established 90% of the
islands as the Galapagos
National Park the same year. Together they have had an established
presence in the islands since the 1960's and are working towards preservation of the
Galapagos
National Park and Galapagos
Marine Reserve.
Human Impact
For many Ecuadorians the Galapagos Islands is a modern day El Dorado offering economic
growth, plenty of work opportunities, and 50% higher salaries than on the mainland. In
a country of 40% unemployment, the draw of the islands is hard to resist. The
population growth in the settlement areas is astronomical and land prices have soared.
The government's attempts to pass laws to curtail the influx of settlers have all
met with opposition from the general populous who feel they too have the right to take
advantage of this bonanza. In 2007 President Correa has put the
conservation of Galapagos as a national priority. The government is now
monitoring the immigration of all those who enter the Galapagos.
Additionally beginning in December 2007 the government began removing people
from the islands who did not have proper documentation.
Tourism is not without its problems. Tourism has grown from 60,000 visitors
in 2000 to more than 150,000 people a visiting
the islands in 2006 the increase in waste disposal the shear number of people and the pressures it
creates on the islands. Many visitor sites with delicate conditions including lava
formations that restrict the size of the boats allowed to visit them in order to
minimize the damage.
Introduced Species
The Galapagos Island's unique ecosystem is based on the lack of competition that some
plants and animals have received over millions of years. The lack of predatory
mammals has allowed tortoises to rule the islands. Since humans began arriving in
the Galapagos, they have brought with them plants and animals that did not occur there
previously.
Herbivores, like goats, compete for the little available
food with Tortoises and Land Iguanas making it so there is not enough food
to support the native creatures.

 Pigs and goats destroy nests and eat bird and reptile eggs. Wild dogs have attacked colonies of Land Iguanas on Santa Cruz and Isabela for sport,
killing hundreds of iguanas and leaving them to rot.
Introduced plants have spread through the islands competing with the native plants for
nutrients. Guava seeds have been planted around the islands by the introduced cattle
and Quinine seeds by the wind. Many of the native plants like Scalesia and Miconia are endangered from the
introduced plants.
The National Park Service is working to eradicate the introduced species and
restrict the import of new species. Park officials and various ships' crewmembers organize hunting parties to eradicate goats, cats, dogs, and pigs. Visitors
are asked not to bring anything onto the island in an effort control the
introduction. They are also asked to wash their feet when returning to the boat in
order to control the spreading of organisms between islands.
Restoring Endangered Species
One of the most successful programs to date has been that of restoring the native
populations. Captive breeding and rearing programs have been enacted. These
programs, combined with the eradication of the introduced species, have led to a dramatic
turn around in several of the islands species.
Land Iguanas were nearly extinct on Santa Cruz and Isabela a captive breeding program
has allowed hundreds of young iguanas to be reintroduced to both islands. That
project, teamed with the eradication of cats and dogs in the region, has allowed the Land
Iguana population to bounce back.
Miraculously a third male was discovered at the San Diego Zoo
and brought to the Darwin Station to join the others in a captive breeding program. These 13 tortoises are the parents of over 300 young tortoises now roam free on
Espaņola.
