A distinct breed of wild cattle, Amsterdam Island cattle, also inhabited the island from 1871 to 2010. They originated from the introduction of five animals by Heurtin during his brief attempt at settlement of the island in 1871, and by 1988 had increased to an estimated 2,000. Following recognition that the cattle were damaging the island ecosystems, a fence was built restricting them to the northern part of the island. In 2007 it was decided to eradicate the population of cattle entirely, resulting in the slaughter of the cattle between 2008 and 2010.
