Feral goats in Australia : ウィキペディア英語版 | Feral goats in Australia
Feral goats are an invasive animal species in Australia. First arriving in the 18th century with European settlers, feral goat populations originated from escaped domestic individuals. Today, feral goats are found across Australia, where they cause economic and environmental damage through overgrazing and competition with livestock and native marsupials. ==History== Feral goats came to Australia with the first fleet in 1788. However, most feral goat populations have a domestic origin. For instance, cashmere goats were brought into South Australia in 1837.〔 In Parkes, John; Henzell, Robert; Pickles, Greg (1996). ''Managing Vertebrate Pests: Feral Goats''. Canberra: Australia Government Publishing Service.〕 In the 1860s, angora and cashmere goats were imported from Asia in an order to start a goat fibre industry.〔 In Parkes, John; Henzell, Robert; Pickles, Greg (1996). ''Managing Vertebrate Pests: Feral Goats''. Canberra: Australia Government Publishing Service.〕 Some herds were set free when the industry collapsed in the 1920s. Goats were also taken around Australia with settlers, railway construction groups and miners. The recent populations of the feral goat have established from goats used to control weeds in plantation forests and woody weeds in inland New South Wales and Queensland. The current feral goat populations in Australia represent a mixture of these origins.〔
