Wildlife Conservation Detection Dog – Dazzy

Dazzy, a Springer Spaniel, is Terrestrial Ecosystems’ conservation detection dog. She has been trained to find Bilbies, Northern Quoll, feral cats and foxes by searching for scats, retreat sites (e.g. dens, burrows, holes) and of course, the animal itself. As part of Dazzy’s training she has been taught to ignore other native fauna and has had snake and bait (i.e. 1080) aversion training for her own safety. Terrestrial Ecosystems also has access to one of the best professional detection dog trainers in Australia, Steve Austin, who provides on-going advice and assistance as required. Where necessary, Steve can travel to WA with other highly trained dogs to support Dazzy if the search area is too large for a single dog, the required time frame is very short or the list of targeted species extends beyond her expertise.

Dazzy is trained to:

  • find cat and fox scats so they can be analysed to identify the presence of cryptic fauna in the area (i.e. marsupial moles, etc);
  • find threatened Bilby and Northern Quoll scats and latrine sites;
  • find the optimum sites to locate traps and camera traps for threatened species and feral animals (e.g. foxes and cats);
  • find fox dens for fumigation;
  • find Northern Quoll dens and Bilby burrows;
  • find diurnal retreats used by cats; and
  • identify habitat utilised by Bilbies, Northern Quoll, feral cats and foxes so it can be mapped.

Wildlife or conservation detection dogs are now widely used in Australia and overseas to locate native and feral animals, their scats and retreats. They are also used to find particular plants and for locating drugs and explosives (Wasser et al. 2004, Smith et al. 2005, Arnett 2006, Long et al. 2007, Cablk et al. 2008, Dematteo et al. 2009, Duggan et al. 2011, Reed et al. 2011, Vynne et al. 2011, Cristescu et al. 2015). Their capacity to find objects using a very well developed sense of smell has also enabled them to assist with finding missing people, and police and other law enforcement agencies use them to locate suspects.

Dogs are very well adapted to locating objects based on their scent as approximately one eighth of their brain and over 50% of the internal nose is committed to olfaction (Syrotuck 2000). We are aware that the Department of Parks and Wildlife has used detection dogs to locate Cane Toads in the Kimberley and the Australian Wildlife Conservancy (AWC) has some specially trained wildlife detection dogs working at its Mornington-Marion Downs property in the Kimberley to locate feral cats.

But how useful are wildlife conservation detection dogs?

Well here is an example. Macquarie Island (12,780 ha) is a World Heritage site administered as part of the Australian state of Tasmania. Rabbits were introduced to the island for food in about 1879. By the 1960s there was increasing concern about damage to vegetation so a rabbit control program commenced in 1978 when the rabbit population had reached ~150,000 with the release of the myxoma virus and this program continued until 2006. The rabbit numbers were estimated at 124,000 in 2006, so there had been some control but the problem remained. All cats on the island had been eliminated in 2000 and in 2011 an aerial baiting program was implemented to kill rabbits and rodents. This was a very successful program, but a small number of rabbits still remained. In July 2011, wildlife detection dogs were used to search the entire island and the remaining 13 rabbits on the island were found and destroyed. Had the last remaining 13 rabbits not been found, then the $25m control and management program would not have been successful, as this small number was sufficient for rabbit numbers to once again increase.

Terrestrial Ecosystems is the first environmental consultancy in Western Australia with a nationally certified and professionally trained wildlife conservation detection dog. Dazzy is available for fox den detection, searching for feral cats, and Northern Quoll and Bilby detection. Knowing that Northern Quolls and Bilbies are in a project area is an important consideration in assessing environmental impacts, and knowing their specific retreat sites and which burrows are active will enable proponents to either plan around these areas and minimise potential impacts, or to trap and relocate individuals out of harms way. Monitoring of Northern Quoll and Bilby populations is also an important aspect of the management of these two threatened species, and being able to locate and census populations using wildlife conservation detection dogs is seen as a very cost-effective alternative to the current live trapping and camera trapping programs.

Dogs don’t have a perceived concept of where the target fauna live, so they will search everywhere. They will work longer, they’ll work harder and they’ll work for a tennis ball reward.
