Help Galapagos excluding invasive species
Galapagos is a natural paradise of the world which welcomes to 170,000 annual visitors. Multiple species has been introduced since XVI century by whalers and buccaneers. It is important to know that an introduced species could become noninvasive species, but an invasive species will always be an introduced one.
The two main factors that promote the entry of exotic species are: augment of human population on the archipelago and arrival of tourists which has increased the food’s demand from mainland to supply the population’s needs. The average amount of products making their way into the archipelago mainly by ships are 56 thousands of tons per year. An important governmental institution that prevents invasive species passing into the archipelago is the Biosecurity Control Agency (ABG in spanish). The ABG’s staff reviews the articles traveling from mainland to the archipelago and between islands. However, personnel deficit in the mainland’s pier avoid to fully comply the inspection of vast volume of loads, examining only 1-2% of 800 tons of fresh food that are shipped to the archipelago monthly. The unchecked cargo could have brought outsider species to Galapagos. There are 1579 infiltrated species: 50 vertebrates, 821 terrestrial plants, 545 terrestrial insects, 77 terrestrial invertebrates, 63 pathogens, 21 marine invertebrates and 2 marine plants, into Galapagos by seaway or airway, among which 50% have been introduced intentionally.
