This study assesses the impact of domestic dogs on the natural environment. The
principal issue investigated is that of disturbance and the consequences for native
wildlife, particularly vertebrate species. In addition to the catastrophic effects of
killing, maiming and orphaning of wildlife; disturbance can contribute to energetic
loss through premature flight or reduced feed intake and reproductive disruption due
to nest disturbance. Dogs have been implicated in disease transmission to native
wildlife; with faecal contamination of waterways having potential negative affects for
marine mammal health. Hybridisation with other canid species is also an issue of
concern, as is expropriation of land for the production of food for pet dogs.
The study commences with an overview of ecological disturbance. The literature
review then assesses the role of domestic dogs in ecological disturbance, public
attitudes towards compliance with dog management legislation and the remediation
and mitigation of disturbance by dogs.
Data obtained from the Resource Management and Conservation section of the
Tasmanian Department of Department of Primary Industries, Parks, Water and
Environment regarding native wildlife presenting for care was analysed in order to
determine the principal reported causes of death and injury to native wildlife in
Tasmania. These results were then compared with data from the Australian Wildlife
Health Centre - Wildlife Hospital at Healesville Sanctuary in Victoria and the data
submitted by Tasmanian veterinarians through a three month diary of wildlife
presentations recorded by ten practices.
