When fire commanders try to figure out how to contain a major wildfire, the last thing you might expect them to deploy is a herd of beef cattle. But on the recent Gold Mountain Fire in western Colorado, cows are eating the “fine fuels” along a three-mile fire line on the Big Cimarron River.
Putting that idea into practice five years ago would have required miles of electric fencing and a range rider to gather strays. Now, new technology has changed the game for cattle grazing by putting electronic collars — all solar-powered — on cows and linking them by satellite.
