Wildfires, invasive grass threaten future of western sagebrush

Humans are the source of 84 percent of wildfires, and not all are intentional. Often they come from vehicle accidents in dry landscapes. In fact, over the last 20 years, 11 of the 50 largest wildfires in the U.S. have occurred in the Great Basin. From 2000 to 2018, approximately 15 million acres of sagebrush burned primarily in the Great Basin, and approximately 9 million of those acres burned from 2014 to 2018 alone, said Michele Crist, a landscape ecologist with the Bureau of Land Management at the National Interagency Fire Center in Boise, Idaho.
