Want to know in more detail about how best to use and set-up fladry? Find out in our Fladry Manual.
A temporary electrified fence with flags hanging to deter large carnivores from entering a space.
Fladry (flagging interspersed on a single strand of twine) is a portable barrier strung around livestock pastures or holding areas. The flagging triggers an innate fear and avoidance in wolves because it is a novel stimulus, By electrifying the fladry, a wolf’s fear response is reinforced with an electric shock. This excellent coexistence tool is not a permanent solution though, and has it’s own set of advantages and disadvantages.
While electrified fladry can potentially be effective in excluding wolves from pastures, it has its drawbacks: high capital costs (approximately $3,000 per mile, excluding labor), limited availability of fladry, and skepticism about effectiveness.
Perhaps most challenging, fladry can be difficult to install, leading some first-time users to abandon this promising tool.
And once fladry has been erected, it can be difficult to maintain. Wind, precipitation, and wildlife can cause fladry to sag, collapse, or become dismantled. It is challenging to build a secure, tight line of fladry.
Along with ranching partners, People and Carnivores has set out to make fladry deployment as efficient as possible.
First, we focused on finding a good way to put fladry on big spools, rather than hand coiling it and keeping it in easily-tangled bags and boxes. We designed and built a device for doing this, with an emphasis on easy replicability so other users can make their own.
Second, we researched and field-tested the best supplies, tools, and electrification equipment we could find.
Third, we borrowed techniques from progressive ranchers to make fladry deployment fast and effective.
The results have been positive: we can now deploy a mile of fladry in less than five hours – a ten-fold efficiency improvement. More importantly, we have distilled our lessons into a comprehensive manual, so that others can learn from our trial and error experiences.
