Nine cattle (the exact breed remains obscure) were introduced to
Enderby Island, the northernmost of the
subantarctic Auckland Islands group, in the 1890s when an attempt was made to establish farming on the island. The attempt failed because of the climate, with the island being abandoned in 1910 and the cattle left behind. Over the 80 years of subsequent isolation the cattle survived well despite the harsh climate, feeding on Enderby's scrub vegetation,
southern rātā, and
seaweed,
evolving to cope with the environment. Cattle had been released earlier, also, in an effort to provide food for
castaways. In 1991, New Zealand's
Department of Conservation decided that species introduced to the Auckland Islands, including cattle and rabbits, should be culled in the course of a program to restore the natural ecosystem. An expedition that year eradicated 47 of an estimated 53 cattle on the island. Genetic material (
oocytes and epididymal
sperm) was taken and stored. A 1992 expedition by the RBCSNZ, to rescue live specimens of the
Enderby Island Rabbit, found tracks of two remaining cattle, a cow and her calf, which were later captured and transferred to New Zealand. ==Description==
