A University of Wyoming researcher says the composition of plant species on Wyoming’s grasslands could be shifting over the next 100 years. That’s one of the results of a study that was conducted to determine how increases in carbon dioxide can affect high-plains grasslands. UW Botany Professor Elise Pendall says cool-season grasses could be replaced by warmer season grasses.
Pendall said that the findings can help ranchers learn to adjust the forage quality for their herds, helping them continue to ranch in a potentially warmer world. The federal Agricultural Research service led the study at the High Plains Grasslands Research Station near Cheyenne.
