Since 2010 we have been conducting research at Mount St. Helens:

  • What happens to plants covered by ash and rock?IMG_5027 We work in forests affected by the eruption! These tephra impacted sites are old-growth forests and adjacent clear-cuts that were dumped on with between 2-15 cm of ash and rock in 1980. Drs. Don Zobel (Oregon State University)  and Joe Antos (University of Victoria) established plots right after the blast, and they have been measuring ever since. The long-term research plots have been measured and maintained since 1980 at a series of sites with different tephra depths.  We have recently completed the 2020 site measurement.  Contact Dr. Dylan Fischer for more on this project.

These are beautiful sites. Come out and see the mountain with us!
