“…Similar bryophyte replacement series are apparent across the boreal forest and are documented in Alaska (Drury, 1956;Heilman, 1966;Viereck, 1970), northern Minnesota (Heinselman, 1963, 1970, northern Michigan (Cooper, 1912), Quebec and Ontario (Auer, 1933), Alberta (Lewis and Dowding, 1926;Lewis etaf., 1928), and Fennoscandia (Siren, 1955). As Sphagnum assumes dominance, there occurs an increase in the thickness and moisture content of the organic horizon and a concomitant decrease in pH, soil temperature, decomposition rates, nutrient availability, and stand productivity (Foster,I983a).…”

“…Observations of this process in southeastern Labrador suggest that this replacement sequence finds parallels in a variety of habitats in which various species groups are involved. As many studies suggest that Sphagnum is of critical importance in vegetation development (Lewis and Dowding, 1926;Wenner, 1947;Tansley, 1949;Swan and Gill, 1970;Walker, 1970;, an investigation of Sphagnum succession should help to elucidate the long-term dynamics of these communities and the role that individual Sphagnum species play in community development.…”

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 Sphagnum girgensohnii overgrowing feather mosses. Similarly, following a change in the water table, Sphagnum lindbergii encroaches as a broad carpet over Cladopdiella fruituns and Gymnocoleu infraru on recently exposed mud bottoms in bog hollows. On bog hummocks, following fire or changes in the moisture regime, Sphagnumfuscum overtops Cladonia lichens to form a pronounced recurrence horizon. Key words: Sphagnum. vegetation development, fire, Labrador, paludification, succession, bryophytes RÉSUMÉ. Une longue rotation d'incendies, des taux élevés de précipitation et la nature acide du sousbassement sont tous des facteurs contribuant à la dominance du Sphagnum dans de nombreuses communautés de terre élevées et de tourbières dans le sud-est du Labrador. La croissance de la végétation provoquée par des changements locaux ou régionaux dans le milieu comprend souvent le remplacement d'établissements d'espkces de divers bryophytes et lichens par des établissements d'espkes dominées par le Sphagnum. Dans les forêts des collines, la séquence de succession suivant un incendie se termine souvent par un tapis de Sphagnum girgensohnii poussant audessus de mousses hypnées. De même, suivant un changement dans le niveau hydrostatique, le Sphagnum lindbergii empiète comme un large tapis au-dessus des Cladopodiellufruirans et des Gymnowleu infrufu sur des fonds boueux récemment exposés dans des creux de tourbikres. Sur les tertres de tourbières, après un incendie ou un changement dans le régime d'humidité, le Sphagnumfuscum croit pardessue les lichens Cladonia pour former un "horizon de retour" prononcé.

“…Group 2 consists of Typha-dominated deep marsh stands that are similar in species composition to Scirpus-Typha reed swamp vegetation identified by Lewis et al (1928), Moss (1953), and a Typha latifolia-Lemna minor open fen vegetation described from central Saskatchewan by Jeglum (1972). Group 2 is intermediate between emergent deep marsh and shallow marsh as defined by Shay and Shay (1986).…”

The wetlands of Elk Island National Park, located in central Alberta, are characterized by their vegetation and relationships between vegetation, surface water chemistry, and hydrotopographic parameters. Thirteen marsh, swamp, fen, and bog communities are described on the basis of TWlNSPAN and the Canadian Wetland Classification System. Species distribution in Elk Island is related to surface water cation gradients of corrected conductivity, pH, calcium, magnesium, and sodium. Hydrotopographic features such as water level, hummock height, elevation of the site, and the number of inlet and outlet streams are of secondary importance. Nutrient levels (nitrogen and phosphorus) in surface waters are less significant. Significant correlations were not obtained between vegetation and surface water nitrate levels or peat depth. Marshes, swamps, and moderate-rich fens at Elk Island are circumneutral in pH and rich in calcium, magnesium, and sodium. Poor fens and bogs are acidic, with lower amounts of mineral cations. The ionic gradient at Elk Island is related to fluctuating water tables and water source (ombrogenous vs. minerogenous). Hydrotopography influences the water chemistry. At Elk Island, marshes and swamps are low elevational wetlands and have the highest number of inlet and outlet streams; fens are found at intermediate elevations with fewer inlet and outlet streams; and bogs are found at the highest elevations with the fewest number of inlet and outlet streams.

“…In Alberta it was reported that 11 sprouts about a foot tall were attached at various points along a 32-foot root (24)." This reference, in turn, is to Lewis et al (1928) who commented on the tendency for a linear arrangement of larch stems on bogs, and of their roots which run from tree to tree and form "slightly raised ridges" or "banks ...( that) rise about 18 inches (46 cm) above the intervening open spaces". They described, however, one case where "several individual seedling larch trees arose from one long root, no less than 11 seedlings about 1 ft. (30 cm.)…”
