Soil moisture regime is an important component of forest land classification at the local level, and in Quebec, it is a criterion for many decisions concerning forestry activities. To facilitate consistent evaluation of soil moisture regime, dichotomous keys were developed for the Abitibi–Temiscamingue region of northwestern Quebec using topographic and edaphic variables and a nonparametric discriminant classification procedure. Probability of correctly classifying a new observation ranges between 63 and 71%, whereas 98–99% of the observations are classified in their moisture class of origin or in an adjacent class.
