Abstract

The modeling methodology includes recognition of cover-states which are similar to successional stages. The general form of the model is ordinary linear differential equations using considerations of stand dynamics and sylvics to determine rates of change. Output from an example model for 250 years of succession in the western Great Lakes Region in the absence of fire, epidemics, and management is presented and discussed. Changes in the model necessary to include management, fire, and epidemics are indicated. The conditions under which the model should simulate succession are stated explicitly. Forest Sci. 19:203-212.
