Testing a New Passive Acoustic Recording Unit to Monitor Wolves

Posted on October 27, 2020

As part of a broader trial of noninvasive methods to research wild wolves (Canis lupus) in Minnesota, USA, we explored whether wolves could be remotely monitored using a new, inexpensive, remotely deployable, noninvasive, passive acoustic recording device, the AudioMoth. We … read more

Transylvania Is Famous For Vampires, But Also Has Lots Of Grizzlies And Wolvestinyurl.com/mryu2ebrKrisztina Gayler has a long history of ranching in grizzly and wolf country on two continents. She grew up on a ranch in Hungary and came to the U.S. in 2005. She maintains strong ties with ranchers here in Wyoming, as well as in Hungary, Romania, and Transylvania.She understands the misgivings ranchers have about large predators such as grizzlies and wolves continue to reclaim more habitat in Wyoming, Colorado, Montana and Idaho.“There’s too much fear-mongering going on here about wolves,” Gayler said. “I think the communication needs to be better among all these groups — ranchers, wildlife biologists and activists.”“Romania is about 90% the size of Colorado, and it has nearly 20 million people and 2,400-2,500 wolves,” she said.The country’s population of brown bears — which she said are essentially the same as grizzlies — isn’t known for certain. But it’s at least 3,000, and possibly as many as 5,000 bears, Gayler said.What’s more, Romanian ranchers aren’t allowed to have guns, or even bear spray.So how do they do it?Ranchers and predators in that part of the world have been sharing the landscape for centuries and have formed what could perhaps be described as an understanding, she said.And ranchers also rely on livestock guardian dogs — bred over hundreds of years to be alert, fierce, loyal and deeply protective of their owners and their flocks of sheep or herds of cattle.“The main purpose of the guardian dogs is not to fight the predators, it is to chase them away,” she said.Centuries of conditioning have acclimated bears and wolves in Eastern Europe to associate sheep and cattle with large, aggressive, loud dogs. And so the predators learned that avoidance is the best tactic.She hopes that getting people talking, and thinking about some Old World ranching methods might help non-lethal control of wolves and bears catch on here. ...
