Abstract
The processes controlling tree-scale spatial heterogeneity in forests have large effects on system-level properties such as standing crop, and on community-level properties such as successional species turnover. A "mean field' version of the forest simulation model SORTIE is developed in which horizontal spatial heterogeneity is eliminated while vertical structure is retained. The mean-field model maintains only approximately one half the standing crop and loses successional diversity approximately twice as fast as the full spatial model. Data from natural stands support the spatial model. Results are set in the context of ongoing efforts to develop models intended to predict the biosphere's response to global change. -from Authors
