Introduction:

For the first field trip, we traveled to Rattlesnake Ridge (north end) and Talus loop on Mt. Si on 04/10/2014. The goals for the trip are listed below.

• How topography affects soils, water and vegetation (Or: Can we use vegetation to tell us about soils, topography and water?)
• Interaction between soils and vegetation
• Role of natural and anthropogenic disturbances (clearcuts, fire, disease, powerlines, roads, and wind) on forest processes
• Learn the major overstory and understory species
• Learn about tree growth and development
• Begin to have a sense of the role of distance from Seattle and elevation play on climate and vegetation.
