Two
species are particularly abundant on Corvallis sidewalks-- Barbula vinealis and
Bryum capillare -- each of which alone accounted for 70-90
percent of the moss cover at their sites. Bryum dominated
at the post office, while Barbula was the principal species
at all of the other locations. Tortula and Scleropodium
covered much less area but were widespread, each turning up in
at least 4 of the 5 sites. The other five species were relatively
rare.
