It has been suggested that foxes contributed to the extinction of the Desert rat-kangaroo.įoxes also cause significant economic losses to farmers by preying on poultry, young lambs, and goats. Many native animals include ground-nesting birds such as the night parrot, and animals such as the quokkas, wallabies, and native rodents, many of which are endangered or vulnerable, fall prey to the fox. Red foxes are indiscriminate feeders, they wreak havoc on native wildlife not accustomed to an apex predator such as the fox. Foxes have already contributed to the extinction of several native animals. They threaten the survival of 48 types of mammals, 14 species of birds, 12 varieties reptiles, and 2 types of amphibians. Red foxes are devastating to Australian wildlife. Red Fox Impact on Australian Ecosystem The Red Fox is a Pest in Australia Today, there are over 7.5 million feral foxes in Australia. Unfortunately, the fox was also devouring native wildlife at prodigious rates. Secondly, humans continued to intentionally introduce foxes into areas that they had not been in before to control the population explosion of rabbits. Firstly, foxes were following a plentiful food supply, namely rabbits. This rapid expansion was due to two reasons. Their expansion closely matched the spread of rabbits, another introduced animal also released in Geelong, Victoria, in 1859. Within just 100 years of their first release in Australia, they had spread across vast distances of thousands of kilometres. Within twenty years of their introduction, foxes were so numerous and destructive that they were officially declared a pest in Victoria. They were reported in New South Wales by 1893, South Australia by 1901, Queensland by 1907 and Western Australia by 1912. Once introduced, foxes spread rapidly throughout the Australian mainland. The average life span of a red fox is between 2 to 3 years. ![]() Young foxes reach sexually mature in 9-10 months and are ready in time for the next mating season. At about three months of age, they start hunting for small prey and are entirely independent by about nine months and set out to establish themselves in new home ranges of their own. Kits begin to make their first tentative moves out of the den when they are about five weeks old, and when they are about nine weeks old, they abandon the den and start to live on the surface. When the kits are about three weeks old, they start consuming regurgitated food that their mother provides them. At about two weeks, the vixen leaves her kits alone in their den while she goes hunting. During this time, the male fox brings her food and regurgitates it to feed her. The vixen remains in the den for the first two weeks after the birth of her kits to feed and protect them. Male and female foxes form monogamous pairs during this time.Īfter a gestation period of approximately 53 days, the vixen gives birth to a litter of 4 to 6 blue-grey coloured babies, called kits. ![]() These social groups consist of a dominant male and female together and several subordinate females who don’t produce litters themselves but help rear the young of the dominant female instead. Foxes generally form social groups only during the breeding season.
