Predation and hybridisation by feral dogs ( Canis lupus familiaris) has been listed as a key threatening process in New South Wales by the NSW Scientific Committee. The current status of dingo populations in NSW is uncertain and the proportion of pure dingoes in remaining populations is not known. However, both pure-bred and hybridised dingos continue to pose a threat to livestock. Wild dog control and loss of habitat also pose a threat to dingo populations. Ongoing hybridisation with feral dogs poses the most significant threat to their persistence in these areas. Previously widespread, dingoes are largely restricted to the Great Dividing Range, coastal hinterlands and the north-west of the state. Their introduction has been linked to the extinction of the thylacine (Tasmanian tiger) and the Tasmanian devil on the mainland. They established across the mainland and on many offshore islands, probably assisted by Aboriginal people.

Conversely, under some circumstances, predation by dogs may have significant direct impacts on threatened species such as koalas.ĭingoes were introduced into Australia from Asia by humans around 4000 years ago. Under some circumstances, wild dogs may also suppress the abundance or activity of other pest animals such as cats and foxes. Predation by wild dogs can reduce the impacts of overgrazing in arid and semi-arid ecosystems by regulating the abundance of native and exotic herbivores. Wild dogs may have both positive and negative impacts on the environment but these interactions and any net outcomes are not well understood. This means that the occupier of lands (both private and public) is required to take all practical measures to minimise the risk of any negative impacts of wild dogs on their land or neighbouring lands. The General Biosecurity Duty requires any person dealing with biosecurity matter (such as wild dogs), and who knows or ought to know of the biosecurity risks posed by that biosecurity matter, to take measures to prevent, minimise or eliminate the risk as far as is reasonably practicable. It is therefore necessary to manage wild dogs under the General Biosecurity Duty of the Biosecurity Act 2015.

As a result, they have been identified as a priority pest animal under the 11 Regional Strategic Pest Animal Management Plans developed by Local Land Services. Wild dogs can have significant impacts on livestock, especially sheep. We work to control wild dog populations in our national parks.Ī wild dog is any dog living in the wild, including feral dogs ( Canis lupus familiaris), dingoes ( Canis lupus dingo), and their hybrids. Wild dogs are a pest animal that threaten livestock and domestic pets.
