NEW research by Biosecurity Queensland will examine how effective guardian dogs are at stopping wild dogs from killing stock.
Primary Industries Minister Tim Mulherin said the project aimed to reduce the tens of millions of dollars a year wild dogs cost the grazing industry in lost production.
"Maremmas are a breed of livestock guardian dog that originated in central Italy and have been used for centuries by Italian shepherds to guard sheep from wolves," he said.
"Using GPS data loggers, we have been monitoring the movements of Maremmas on a Queensland property.
"The loggers record locations every 30 minutes, testing the theory that guardian dogs act like 'placebo' wild dogs, marking a territory that is avoided by wild dogs.
"We are interested in how far beyond their paddocks guardian dogs patrol and whether there are any gender or individual differences in daily movement patterns.
"If successful, the 'guardian' method would give graziers confidence in a non-lethal method of controlling wild dogs on their properties," Mr Mulherin said.
North-west Queensland sheep and cattle producers Ninian and Ann Stewart-Moore believe their Flinders Shire property, Dunluce, remained 'in sheep' only because 24 Maremmas protected them from wild dogs.
"We were losing 15 per cent of our 20,000 sheep flock each year, mostly to predation, and could no longer control the losses with regular wild dog baiting," Mr Stewart-Moore said.
"Since purchasing a team of Maremmas in 2002, our losses are now an acceptable 3 per cent and are mostly from causes other than predation.
"The outlay for all of our Maremmas was less than the cost of our losses from wild dogs each year.
"Potentially, there is a huge role for using livestock protection dogs in the grazing industry now, particularly for protecting both sheep and goats," Mr Stewart-Moore said.
Biosecurity Queensland senior zoologist Lee Allen said that he had preliminary data on how individual guardian dog movements differed, but the next phase was to monitor wild dogs in the immediate area.
"We plan to 'capture' and 'collar' the wild dogs that live on the properties adjoining Dunluce to see how the movements of guardian dogs and wild dogs overlap," he said.
"There may also be conservation benefits from using guardian dogs.
"Maremmas may provide some of the biodiversity benefits of having dingoes without compromising livestock production values.
"One line of thought is that dingoes might reduce the numbers and alter the behaviour of overabundant kangaroos and associated grazing pressure.
"They may also deter smaller predators such as feral cats and foxes, which have had devastating impacts on our native fauna.
"We intend to repeat this study on a beef cattle property elsewhere in north west Queensland where wild dogs are common, in 2011."
