Résumé :	P> We used replicated, repeated-measures data to examine the spatio-temporal structure of multi-storied, multi-aged interior Douglas fir (Pseudotsuga menziesii var glauca (Mirb.) Franco) stands growing on dry sites under more than 50 years of fire protection. Along with the univariate and bivariate Ripley's K and related functions, we used a random coefficients mixed model to investigate the variation in these functions over replicates and time. The spatio-temporal analyses revealed that trees greater than 1.3 m in height were clustered over space, and clustering was more evident for small trees (i.e. diameter at breast height (d.b.h.)
