There are also non-native red-necked wallabies, introduced by Rupert Baring in the 1950s, and augmented by a surplus from Dublin Zoo in the 1980s, numbering perhaps around 100 in 2017. The wallabies breed well, and some moderate culling is required to keep the population under control. Fallow deer were introduced, and by the mid-2000s formed a herd of about 200. There is also a herd of farmed cattle on the island, and a flock of sheep.
