University of Montana forest ecology Professor Andrew Larson recently published research estimating the abundance of morel mushrooms after a wildfire in California's Sierra Nevada. "So many people love to harvest and eat morel mushrooms," Larson said, "but there is very little research that measures the abundance of morels after a forest has burned. We wanted to give forest managers concrete data on morel abundance."
