The Dynamics of <i>Sphagnum</i> in Forest and Peatland Communities in Southeastern Labrador, Canada

Abstract: 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 Sph… Show more

“…Although peatlands in eastern North America are morphologically and floristically similar to those of northwestern Europe, until recently there have been few investigations of their stratigraphies and paleoecologies (WELLS, 1981 ;DA-VIS, 1984;FOSTER, 1984;FOSTER and KING, 1984;COUILLARD and PAYETTE, 1985;ZOLTAI and JOHN-SON, 1985). Banded profiles have been noted by FOSTER (1984) and by GLASER and JANSSENS (1986).…”

“…Charcoal, however, is ubiquitous in boreal soils (for example, Trumbore and Harden 1997), and its presence alone is no proof that peatland initiation was a direct result of fire. In fact, fire can play an important role in maintaining black spruce-feather moss systems by periodically removing bryophyte mats and soil organic layers (Foster 1984;Fenton and others 2005), thus preventing the lateral spread of Sphagnum.…”

“…In many cases, the boundaries between these different community types are dynamic, and given suitable hydrotopographic conditions, swamps and their adjoining fens can spread outward into adjacent uplands (Heinselman 1970;Foster 1984;Warner and Rubec 1997;Bauer and others 2003). Conversely, decreased water levels result in increased tree productivity and may lead to a contraction of wetland boundaries (Hartshorn and others 2003).…”

“…We can explain the continuous regeneration of P. sylvestris by presence of Sphagnum hummocks. In late post-fire successional stages of upland forest communities in eastern Canada Sphagnum species can be the dominant species for long periods of time (Foster 1984). However, we lack information on the dynamics of Sphagnum patches and the past growth conditions in the studied mire.…”
