Red foxes in Australia
Red foxes pose a serious conservation problem in Australia. Current estimates indicate that there are more than 6.2 million red fox (''Vulpes vulpes'') and growing with a range extending throughout most of the continental mainland. The species became established in Australia through successive introductions by settlers in 1830s. Due to its rapid spread and ecological impact it has classified as one of the most damaging invasive species in Australia.
==Introduction and spread==
Red Foxes were introduced to the British colonies of Van Diemen's Land (as early as 1833) and the Port Phillip District and Sydney Regions of New South Wales (as early as 1845) for the purpose of the traditional English sport of fox hunting. Curiously a permanent fox population was not established on the island of Tasmania and it is widely held that they were outcompeted by the Tasmanian devil. On the mainland, however, the species was successful as an apex predator. The spread of red foxes across the southern part of the continent has coincided with the spread of rabbits in Australia, another invasive species also introduced in the 19th century that is a key prey of the red fox.
