In this time-lapse video, a series of false-color images collected by USGS-NASA Landsat satellites from 1987 to 2018 show the burning and gradual regeneration of Yellowstone’s forests following the 1988 fire season.
Landsat Project Scientist Jeff Masek talks about how Landsat satellites detect the burn scars from space and distinguish them from healthy, un-burned forest and from new growth. Watch as burn scars (dark red) quickly replace large expanses of healthy green vegetation (dark green) by 1989. Notice how the scars slowly fade over time as new vegetation begins to grow and heal the landscape.
