Introduced mammals have become a pest. As well as introduced rodents there are feral cats. Rabbits were formerly a major pest, but numbers have decreased following control measures such as warren ripping and the dissemination of rabbit haemorrhagic disease. Foxes are baited to reduce their population in rural areas. Wild horses occur in the Namadgi National Park and adjacent Kosciuszko National Park where they are called brumbies; although environmental pests, ACT residents have opposed killing them. Pigs live in the mountains and damage plants; they are controlled by hunting and poisoning. Fallow deer and wild goats occur in low numbers. Feral dogs interbreed with, and threaten the genome of, dingos; both are trapped and baited on the edge of rural properties to protect sheep.
