Assessing the real cost of wild dogs

Published 21 February 2018

Wild dogs pose a significant threat to livestock in the New England and, until now, calculating the economic cost of these cunning predators has proven difficult.

Not to be outwitted, University of New England PhD candidate Salahadin Khairo, an economist with the NSW Department of Primary Industries (DPI), is surveying landholders to evaluate the economic impact of wild dog control in communities throughout the Northern Tablelands and North Coast. It is the first economic assessment of the impact of dogs in northern NSW for 30 years and aims to inform strategies to manage them.

“The cost of wild dogs in dollar terms is hard to estimate, especially as many losses are not reported,” said Salahadin. “Whether it’s a sheep or mixed livestock property, the average number of livestock lost to wild dogs per year could be in the range of 14 sheep and four cattle. This could cost individual farms from $2,000-$7,000 each year, depending on the location, time of year and nature of the enterprise. Whatever the case, it’s a significant cost to producers – so significant that it’s forcing some landholders to shift from sheep to cattle or out of livestock production altogether.”

Northern NSW wild dog facilitator David Worsley says that at least 3870 head of livestock were reported killed by wild dogs in the Northern Tablelands from June 2015-June 2017 and all but 56 were sheep.

The mobility of wild dogs means that one land manager’s efforts may potentially benefit another some distance away, and vice-versa. Ground and aerial baiting, exclusion fencing, guardian animals, trapping and shooting remain the most common control measures. Salahadin said landscape-scale management, using a combination of techniques and policy mechanisms, has been shown to increase the cost-effectiveness of control.

He hopes to enlist about 800 landholders on large and small properties, including remote farms and those closer to urban areas, to complete the survey periodically between now and 2021. It seeks information on precise numbers of stock lost and mauled, approaches to dog control, and how losses have influenced stocking rates and other business decisions, to better represent the full economic cost of wild dogs.

“The survey will help us to understand the impact and management of wild dogs over time, and to develop a pattern of predation,” Salahadin said. “Ultimately, this information will help farmers to manage dogs more effectively, by giving them the evidence they need to adopt effective strategies.”
