Abstract: 5 figures. [Review of the lichen-rich terricolous communities in tundra and taiga zones across the Arctic, including Canada, northern Europe and Siberia. "Their epigeic lichen synusiae are usually dominated by four fruticose Cladina species, being extremely homogeneous in species composition and structure throughout the boreal zone, while the dominant trees and other vascular plant flora of the woodlands are geographically more variable." The authors also discuss problems of habitat destruction and conservation needs.]
