The following bryophyte species list compiles habitat information based on the quantitative data collected from 360 samples (2 x 4 m quadrats) distributed among 42 sites within the Andrews Forest. The sites range from 420 m to 1250 m asl stream orders 1 to 5. The list comprises 131 taxa, 84 mosses and 47 hepatics. Many of the species were however infrequent and thus detailed and objective accounts of their habitat demands are difficult to provide. The data is specific for the studied sites but may serve as an indication of the general habitat demands of the species within the western Cascades and to some extent for riparian zones in the Coastal Mountain Range. Voucher specimens have been deposited at the herbaria Oregon State University and UME, Sweden.

The purpose of this study is to provide a basic description of bryophyte communities in riparian forests, to identify relations between community patterns and major environmental gradients, and to make comparisons of local microsite factors with site level influences.
