This paper reports on the progress in developing a field reference for the identification, description, and assessment of rare ecosystems in British Columbia for the Conservation Data Centre (CDC). To this end, a review of plant community classification concepts is provided. Concepts discussed include (1) the relationship between the plant community and the plant association, (2) vegetation classification concepts used in the biogeoclimatic ecological classification system, (3) clarification of classification concepts and the B.C. CDC’s Red- and Blue-listed plant communities, and (4) plant community rarity—the nature of the threat. Management implications and recommendations are outlined as a starting point for further discussion.
