The history of man´s
detrimental effects on the islands extends back to the 1600s when buccaneers
introduced the first goats and killed tortoises for food.
Once settlers came to the islands they brought with them a full range of
domestic animals, some of which went wild and
started feral populations.
Dogs, cats, pigs, goats, rats, the little fire ant, guava plants, and the chinchona (quinine) tree. Introduced plants have spread, particularly in the
moist highlands, and compete with native vegetation. Several species are
considered to be serious threats to native vegetation.
On the other hand, the social
and environmental pressures made by the fast population growth of the
Galapagos inhabited areas worry the national and International communities.
Between 1982 and 1990 the population growth rate in Galapagos reached 6
mostly due to migration from the Ecuadorian mainland. During 1996 a step forward'in this direction was the introduction of an amendment to the
Constitution of Ecuador which states that Galapagos will have a special
regimen. Therefore, at this point, it'is possible in to restrict migration,
commerce and property rights in Galapagos.
Two organizations work
together for the conservation of the island: the Galapagos National Park (GNP),
that tries to keep the natural resources of the Islands in the best state of
conservation possible and the Charles Darwin Research Station, which
conducts and facilitates research in the Galapagos Islands. |
