Island in the Galápagos archipelago where goats have been removed.

<p>*Includes eradication efforts from 1999–2003; does not include prior control efforts.</p><p>Goats have been removed from over 700,00 ha for a cost of $12 million. Cost data for earlier eradications are not available. Goats have been reintroduced to islands nine times, which has cost more than$266,000 to remove those new populations. Goats remain on the three islands in bold, where removal efforts are underway. All costs are in 2009 US$.</p

The use of the threat of goat reintroduction to islands in the Galápagos as a political tool.

<p>A sign during a 2004 local protest at the Galápagos National Park headquarters, where local fishermen were demonstrating for additional fishing permits. The sign threatens to introduce goats to Fernandina Island, which is the only large island in the archipelago that does not have a history of introduced herbivores.</p

Southern Isabela is, separated from the northern section by a 10+ km-long lava isthmus (Perry Isthmus).

<p>A small town, Puerto Villamil, is located at the southern tip of the Island. a) The Galápagos archipelago. b) Isabela Island.</p

The marginal cost curve of removing goats from Santiago Island, Galápagos (2001–2006).

<p>The majority of the 79,569 goats removed cost between US$10–100 per goat to remove. The final goats, however, cost over$10,000 per goat. Technologies and tools targeted at cost-effectively removing the final animals of an eradication campaign could deliver in substantial savings to island restoration programs.</p
