Revealed: how to protect livestock from predators
Published today in PLOS Biology, the review of 114 scientific studies measuring the effectiveness of lethal and non-lethal methods concluded that guardian dogs, livestock enclosures, and are all effective deterrents.
Many other methods鈥攂oth lethal and nonlethal鈥攕how promise but have not been studied in a scientifically defensible manner to determine if they are effective.
In addition to determining the effectiveness of three nonlethal tools, the study authors say robust scientific research on carnivore management methods is urgently needed.
Too often our current practices are based on habit and history, not evidence.

鈥淐ontinuing with ineffective management has social and financial costs for the rural communities who bear the impacts of predator attacks on their livelihoods,鈥� she said.
In Australia, dingoes, cats, foxes and kangaroos are major predators of livestock, crops and native fauna.
Evidence of the effectiveness of a deterrent should be a mandatory prerequisite to large-scale funding, policy-making and implementation, say the authors.
The authors are also calling for a new coalition of scientists and managers to establish consistent standards for future research on method effectiveness.
, a lead author of the study and senior scientist at Defenders of Wildlife said:
鈥淥ur study found that livestock guardian dogs, livestock enclosures, and fladry are scientifically-sound management tools, and these methods can be used and promoted as reliable methods for deterring predators and protecting livestock.
鈥淗owever, many other interventions, including predator lethal control and translocation but also newer methods like range riders and light-sound devices, need to be further tested to ensure they are effective before being recommended for widespread use.鈥�
