Relationship between number of microhabitats (N microhabitats per tree) and Diameter at Breast Height (DBH, cm) by genera (beech: Fagus sylvatica; fir: Abies alba; oak: Quercus spp., pine: Pinus spp. and spruce: Picea abies) and living status (living vs. dead standing trees).

Lines represent estimates from generalized mixed effect models with a Poisson error distribution and plot nested in site as a random effect. Ribbons show the 95% confidence intervals of the mean. For this representation, pH and elevation were held constant (mean values in our data set).
