This paper presents new models for marked point processes for describing forestry data. In these models two factors play a role: Long‐range variability is modeled by a random field, which may describe environmental variability, while short‐range variability is caused by the interaction of points of two classes. These models may help in the interpretation of empirical mark variograms as is shown by two examples from forestry statistics.
