Abstract:

The SPACE model is a spatial model of forest dynamics. It is a spatial adaptation of FORET (minus the climate routines) with horizontal detail. Unlike most forest "gap models" the locations of individual tree stems are tracked. A neighborhood approach is used to model interactions among trees. The model is designed for study of vegetation dynamics at multiple scales in time and space.

VI. Additional remarks

This is a 3-D gap model with emphasis on forest community dynamics and spatial pattern. A 1997 version features spatially non-random seed dispersal from adult trees.
