The dynamics of a deciduous forest stand growth model are examined with regard to variation in the simulated plot size. As the plot size in the model is decreased, the importance of the shading interaction is diminished and the effects of root competition is increased, preventing any tree from reaching its maximal size. As the plot size increases, root competition diminishes and shading or canopy interactions dominate, eliminating shade intolerant species. If the plot size is too large then the death of a single tree is insignificant in the canopy dynamics and gap phase replacement does not occur. The contrasting effects of plot size on the importance of root and crown competition provides a quantitative basis for identifying the size of a forest stand based on community level dynamics. Forest Sci. 25:120-122.
