Silly as it may sound, it just might be a helpful new way to protect valuable livestock. Wolves, bears, cougars and coyotes are important parts of ecosystems of the West — and a pain for people who raise livestock there. FLASHTAGSUtah State University’s Department of Wildland Resources and the Ecology Center reports that this new technology, FlashTags, are motion-activated LED ear tags that can be worn by livestock. FlashTags are a low-maintenance, low-cost, portable and nonlethal tool that shows exceptional promise against wolves and coyotes, Young said. The owner of the test-herd was even convinced that the FlashTags helped, according to Ms. Young.
