Figure 1. Vegetation on ultramafic rock types at lower elevations (approxi- 
mately 500m) at the southwest Oregon study area. The left photograph illu- 
strates an open pine grassland developed on serpentine soils while the photo- 
graph on the right illustrates a dense sclerophyll shrub layer beneath scattered 
pines on largely unserpentinized peridotite.
