Brian Mealor scanned the prairie east of Buffalo, but his mind drifted west to a haunting scene in northern Nevada. In the burn scar of the Roosters Comb Fire, a single unwelcomed species had taken over, choking out all competitors. Mealor saw few native grasses or shrubs, scarcely a wildflower. Not even other weeds. “Literally everything you see is cheatgrass,” Mealor recalled of his June tour of the scar. “I just stood there, depressed.”
Mealor already knew plenty about the Eurasian species’ capacity to decimate North American ecosystems since he leads the University of Wyoming’s Institute for Managing Annual Grasses Invading Natural Ecosystems. But he was still shocked walking through the endless cheatgrass monoculture taking over the 220,000 once-charred acres northwest of Elko. The same noxious species, he knew, is steadily spreading in Wyoming.
The ecological scourge made Silver State officials so desperate that they were planting another nonnative, forage kochia, because it competes with less nutritious cheatgrass and offers some nourishment for native wildlife, like mule deer. “They’ll just die, because there’s nothing there,” Mealor said. “That’s why we have to do stuff. Because we could turn into that.”
Scientists, rangeland managers and state and county officials are doing everything in their power to prevent Wyoming from becoming another landscape lost to cheatgrass. There’s a powerful new herbicide that’s helping. And funds enabling the spraying of hundreds of thousands of acres are being secured and raised. Yet, Wyoming is still losing its cheatgrass fight, and ultimately far more resources are needed to turn it around.
“Let’s not kid ourselves,” said Bob Budd, executive director of the Wyoming Wildlife and Natural Resource Trust. “The magnitude of the need is utterly staggering. We’re talking hundreds of millions of dollars over the next decade. That’s daunting.”
Budd voiced that warning Tuesday while addressing a statewide group that focuses on bighorn sheep, which depend on seasonal ranges being invaded by cheatgrass. A recent study co-authored by Mealor underscores the need to act soon to protect Wyoming’s wildlife. UW researchers concluded that cheatgrass, which is only edible in spring, could cost northeast Wyoming’s already struggling mule deer half their current habitat in the next couple of decades.
