Résumé

The ecological factors most closely associated with the distribution of the 11 identified communities are soil drainage and richness. These 2 factors are strongly related to the types of surface deposits. Communities dominated by Acer saccharum are found on well drained and nutrient-rich moraines. Communities dominated by Acer rubrum and the majority of coniferous forests are found on poorly drained and nutrient-poor soils. Two floristically distinct community types, the Fraxinus-Tilia americana forests and the Tsuga canadensis-A. saccharum forests, are found on poorly drained marine deposits with edaphically identical lower horizons, but the pH and major cation concentrations of the upper soil horizons are much lower under the cover of the hemlock forests than under the cover of the ash-basswood forests. -from English summary
