Feral donkeys in Australia
Feral donkeys in Australia (and elsewhere) are donkeys (scientific name ''Equus asinus'') which escaped from captivity, and are living and breeding in the wild.
Donkeys originated in Africa and also parts of Asia. They are a part of the Equidae family. While donkeys display many horse-like characteristics, they are more closely related to wild asses.
Donkeys were brought to Australia from 1866 for use as pack and haulage animals.〔 Up until that point, the Australians had been using the horse as their main mode of transportation. However, problems arose when the horses used in transportation began to become sickened by some of the native poisonous plants. When donkeys proved to be invulnerable to the plants that were making the horses sick, more donkeys were brought in. Escape was common because of the lack of fences, and there were reported herds of donkeys by the 1920s. In western Australia in 1949, there were enough donkeys for them to officially be declared a pest.〔 There were almost 5 million feral donkeys in Australia in 2005.〔
==Food sources==
Donkeys are herbivores, and only eat vegetation. All year round, the donkeys graze for grass, shrubs, and tree bark. Donkeys usually graze for 6 to 7 hours a day and can go a fair distance from water sources.〔 There are over 5 million donkeys living in Australia, which means that the donkeys eat a significant amount of vegetation.〔 The donkeys can readily find food in winter if it is wet; however food is much less plentiful in times of drought.
