Andrea Watts, our correspondent in the U.S. Forest Service, now writes for the Rocky Mountain Research Station (@usfs_rmrs)—for example on how to predict how many trees died in a forest fire. She still writes for the Pacific Northwest Research Station (@usfs_pnwrs), too. Recent stories are on managing invasive plants and outflow from Spirit Lake, which NSWA members know from the Mount St. Helen’s trip.
