註釋"The 2013 Oregon Biodiversity Information Center's (ORBIC) species of concern list identifies one hornwort, 39 liverworts and 102 moss species occurring in Oregon as rare, threatened or endangered. This Bureau of Land Management publication provides for each species current nomenclature, distinctive taxonomic characteristics, technical description, similar species, ecology, mapped known distributions, references, and a photomicrograph plate. This work gives a much-needed review of known species locations by both county and ecoregions. Additionally, this publication includes species proposed for inclusion into the 2016 ORBIC list."--Page iv.
