Wildflowers anchor watershed This high-elevation meadow is called a 'tall forb' community -- fields of wildflowers that grow between 6,300 and 11,000 feet in parts of Montana, Idaho, Utah and Colorado. The unique meadows culminate in wildflowers, not trees. According to experts, a healthy 'tall forb' meadow can stand thigh and even waist high. This particular meadow, though, is only tickling our shins. But now a unique partnership between a rancher and some government and conservation groups has created an opportunity to give this high-elevation meadow a break from domestic sheep grazing in an attempt to accelerate its recovery. Ultimately, the plan is to return sheep grazing to the mix -' albeit at lighter frequencies than in the past. In the early 1900s, ranchers ran an estimated 150,000 to 200,000 sheep from the south end of the Wyoming Range to the north and back again each summer, explains Steve Kilpatrick, a habitat biologist for Game and Fish. 'That was before we knew how fragile the tall forb communities are,' Kilpatrick says. 'Once it unravels it's just difficult to get it back.' Historically, heavy grazing meant there was less plant material on the land to anchor the soil and soak up the rain. So the black, loamy topsoil washed away, leaving bare ground. Those are the conditions Jim Magagna's family inherited when they started grazing sheep in the Wyoming Range in the 1940s. Moreover, concerns about predators encouraged ranchers to bed sheep at night in big numbers to protect the lambs and ewes from coyotes and other carnivores, Magagna says. Over time, however, Magagna acquired and consolidated nearly 60,000 acres of grazing leases on the national forest. By using guard dogs to protect the sheep from predators, he was able to spread them out to lighten their impact on the land, he says. With that in mind, Trout Unlimited brokered a deal with Magagna to give the high-elevation meadows time to heal. Under the agreement, Magagna waived his option to graze four bands of sheep yearly on nearly 60,000 acres in exchange for $209,904 in compensation. The payment comes from a variety of contributors including fishing, hunting and conservation groups....
