Population Dynamics of Fraxinus nigra in Response to Flood-Level Variations, in Northwestern Quebec

Abstract: Population dynamics of black ash (Fraxinus nigra) were investigated in five stands with different exposures to spring flooding at the southwestern limit of Québec's boreal forest. Fifty-four 100-m 2 plots were sampled along 25 transects laid out perpendicular to Lake Duparquet. In each plot, all black ash Ͼ5 cm in diameter at breast height (dbh) were aged using dendrochronological methods. An age-height regression was used to calculate the age of those individuals Ͻ5 cm in dbh. Stump sprouts had a significantl… Show more

“…The importance of overstory tree cover in regulating water table dynamics during recruitment events has also been reinforced by examinations of the age structure of old-growth examples for these two habitat types, which indicate these systems are strongly multi-aged with historic development influenced primarily by gap-scale disturbances (Figure 1; D'Amato et al in prep). A similar multi-aged population structure was also documented across numerous old-growth black ash riparian forests in the Lake Duparquet region of Quebec [26]. Age structure for two old-growth black ash forests in Minnesota.…”

“…One might expect, therefore, considerable spatio-temporal heterogeneity in levels of genotypic diversity both within and between populations of the same species where resources/disturbances are themselves not equally distributed in space and time (Held, 1983;Rood et al, 1994;McKay, 1996;Gom and Rood, 1999;Tardif and Bergeron, 1999;Barsoum, 2002). Clearly defined relationships between levels of sprouting in clonal woody species (as reflected by levels of genotypic diversity) and environmental factors that promote sprouting are, nevertheless, very difficult to establish.…”

“…The elmred maple-black ash type grades into an almost pure black ash type on poorly drained sites with organic peat and muck soils, where it has been considered as the climax species (Erdmann et al, 1987). Tardif and Bergerson (1999) noted pure stands of black ash in the northern portion of its range, along lakes and rivers. Black ash communities on boreal forest floodplains were identified by Tardif and Bergeron (1992), who used a cluster analysis to produce four vegetation types: (1) black ash/speckled alder (Alnus rugosa)/bog willow (Salix pedicellaris), (2) black ash/balsam poplar (Populus balsamifera)/ostrich fern (Matteuccia struthiopteris), (3) black ash/pussy willow (Salix discolor)/sensitive fern (Onoclea sensibilis), and (4) black ash/speckled alder/sensitive fern.…”
