Managing Forests To Manage Wildfires
Plant-covered land is red in the June 21 false-color image of the Wallow fire burn scar. Patches of unburned forest are bright red. Flecks of black indicate some burning. The charcoal-colored areas burned severely. NASA Earth Observatory image by Jesse Allen using data from the NASA/GSFC/METI/ERSDAC/JAROS, and U.S./Japan ASTER Science Team.
Record breaking fires in the Southwest have burned thousands of acres, disrupting people and animals, and leaving muddy, flood-prone landscapes in their wake. In this remote broadcast from Flagstaff, Arizona, Ira Flatow and guests discuss fire ecology, and how new forest management strategies may help stifle the blazes.
