L'environnement des éricacées des forêts de l'est du Québec
|Authors:||Laberge Pelletier, Caroline|
|Abstract:||The objective of the present ecological inventory was to characterize the presence of three common ericad species: Rhododendron groenlandicum, Vaccinium species and Kalmia angustifolia, in Quebec North Shore forests, and to better understand their presence in relation to environmental factors. Ninety-seven sites within the undisturbed black spruce-feathermoss (Picea mariana) forest north of Baie-Comeau were selected for the study. Rhododendron had the highest mean cover, followed by Vaccinium and Kalmia. The presence of these species was associated with an open forest canopy, acid, coarse-textured and nutrient-poor soils. Ericads were strongly associated with black spruce-dominated forests, with presence decreasing as the balsam fir (Abies balsamea) component increased. Four vegetation associations were identified, including an Ericad-lichen group that included the three ericads and three Cladina species. Results may be used to help identify and classify sites vulnerable to ericaceous invasion after forest harvest.|
