On the side of a rocky hill in Sheridan County in northern Wyoming, Brain Mealor is showing off all of his weeds.
“Here, let me grab a cheatgrass so you can see it, too,” he said, plucking a wispy sprig from among the grasses. “They all kind of look the same this time of year.”
Mealor is the director of the University of Wyoming’s Research and Extension Center in Sheridan. He’s performing experiments on how to manage and kill invasive annual grasses, like cheatgrass, ventenata and medusa head, with herbicides.
