Which country has the highest amount of feral (wild animal descended from domesticated) camels?

Australian feral camels are feral populations consisting of two species of camel: mostly dromedaries (Camelus dromedarius) but also some Bactrian camels (Camelus bactrianus). Imported into Australia from British India and Afghanistan during the 19th century for transport and construction during the colonisation of the central and western parts of Australia, many were released into the wild after motorised transport replaced the use of camels in the early 20th century, resulting in a fast-growing feral population.

By 2008, it was feared that Central Australia's feral camel population had grown to about one million 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. An AU$19 million management program was funded in 2009, and, upon completion in 2013, the feral population was estimated to have been reduced to around 300,000.
