  • Snags in various stages of decay are very crucial to the ecosystem.

  • Coarse woody debris from fallen giants and standing dead snags make important wildlife habitat

  • Students in Professor Jim Cronn's Forest Ecology class have numbered, measured, evaluated and recorded each specimen into a database. The students are then able to track the status of each tree in order to determine such things as health, growth rate and wildlife associations.
