Description :
The aims of this study were to 1) determine the charcoal pools in Ah horizons of the Boreal Transition ecoregion, and 2) use the charcoal data to infer vegetation dynamics and the development of Ah horizons as a function of the main parent material types in the ecoregion (glacio-fluvial, glacio-lacustrine and glacial till). The latter objective served to provide information in regards to future vegetation shifts and ecosystem C budgets of Boreal Plain ecosystems under climatic warming. The results suggest that fluvial sites may be the first shifting to herbaceous vegetation in the future, followed by till sites and then lacustrine sites.
