Mt. St. Helens' Bad Grass


This video is not currently available. We apologize for any inconvenience.

After the eruption of Mount St. Helens, non-native grass was planted to prevent erosion. Scientists worry that seeding was a mistake, as erosion could have actually aided the recovery process, uncovering native species that survived the blast. A once in a life time opportunity to study the process of natural restoration, Scientists fear that human intervention has forever altered the face of Mount St. Helens’ recovering ecosystem.
