Australian feral camels are introduced populations of dromedary, or one-humped, camel (Camelus dromedarius—from North Africa, the Middle East and the Indian Subcontinent). Imported as valuable beasts of burden from British India and Afghanistan[1] during the 19th century (for transport and sustenance during the exploration and colonisation of the Red Centre), many were casually released into the wild after motorised transport negated the use of camels in the early 20th century. This resulted in a fast-growing feral population with numerous ecological, agricultural and social impacts.
By 2008, it was feared that Central Australia's feral camel population had grown to roughly one million animals, and was projected to double every 8 to 10 years. Camels are known to cause serious degradation of local environmental and cultural sites, particularly during dry conditions. They directly compete with endemic animals, such as kangaroos and other marsupials, by eating much of the available plant matter; camels may further thrive as they are able to digest many unpalatable (to other mammals) species of plants. Camels are known for their abilities to survive without water, using fat reserves stored in their hump; however, when a source of hydration is available, even a small herd can consume much of the available water, and soil the water in the process (making it unsafe for drinking by other animals, and creating a pathogen-fostering environment).
The feral camels in Australia are also known to be aggressive when they encounter herds of domestic livestock, such as cattle, sheep, and goats; they can also be dangerously territorial towards people, especially females with newly-born camels and males in their rut. In general, the mating season is known as a hazardous time to be close to camels, of either sex. Pastoralists, representatives from the Central Land Council, and Aboriginal land holders, in the affected areas, were those amongst the earliest complainants. An AU$19 million culling program was funded in 2009, and by 2013 a total of 160,000 camels were slaughtered, estimating the feral population to have been reduced to around 300,000. A post-kill analysis projected the original count to be around 600,000, an estimating error from the original number greater than the totality of the cull.[2]
