Belland, René J. 2011. Rare mosses from siliceous regions in the Northern Rockies, Alberta, Canada: additions and significance Davidsonia 21(1):3-23

This study documents the occurrence of 62 rare mosses from siliceous regions within the northern Canadian Rocky Mountains. Ten species are reported as new to Alberta, and an additional three species are confirmed for the province. Additional records are documented for 49 mosses. The high diversity of rare silicolous species emphasizes the importance of this siliceous flora in the province. In addition, the large numbers of new occurrences significantly add to the knowledge of rare moss distribution in Alberta and diminishes the support for a rare species “hot spot” centred in the northern Rockies. The numerous additional records underscore the importance of inventory work for use in monitoring and environmental assessment.
