 often in excess of this. The floor of the 

 forest is heavily shaded and supports 

 relatively few deciduous under-trees, 

 although there is usually a rich growth 

 of shrubs and of ferns, mosses, and other 

 herbaceous plants. The trees which 

 characterize this area are the Douglas 

 fir {Pseudotsiiga mucronata), redwood 

 (Sequoia sempervirens), western hem-
