Abstract

Long fire rotation, high levels of precipitation, and acidic nature of the bedrock are factors contributing to the dominance of Sphagnum in many upland and peatland communities in southeastern Labrador. Vegetation development induced by local or regional environmental change frequently involves replacement of species assemblages of various bryophytes and lichens by species assemblages dominated by Sphagnum . In upland forests the successional sequence following fire often culminates in a carpet of S. girgensohnii overgrowing feather mosses. Similarly, following a change in the water table, S. lindbergii encroaches as a broad carpet over Cladopodiella fluitans and Gymnocolea inflanta on recently exposed mud bottoms in bog hollows. On bog hummocks, following fire or changes in the moisture regime, S. fuscum overtops Cladonia lichens to form a pronounced recurrence horizon.
