The Dynamics of Sphagnum in Forest and Peatland Communities in Southeastern Labrador, Canada
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 repl...
