The aim of our study was modeling the relationship between the tree height and diameter at breast height (DBH) with dependence of host taxa and mistletoe infection intensity. Ten woody species have been selected for this study from 5 genera (Acer, Crataegus, Juglans, Robinia and Tilia) representing more than 3,000 individuals whereof about 1400 are already infected. The examined host taxa can be found in the castle park of Lednice in Czech Republic. The park is in the centers of the mistletoe distribution in this region. Logarithmic regression was chosen characterizing this relationship because these two dendrometric variables relatively accurately and simply. From the obtained result, it can be clearly established that as the infection intensity increases, the relationship between the height and DBH decreases proportionally. The difference was also statistically significant for several other host species. However, the exact modelling of this relationship is more complicated, because the negative effect of mistletoe may differ within host species too.
