The aim of this study is to determine (1) whether the yellow mistletoe (Loranthus europaeus Jacq.) favors attacking only the certain species of the genus Quercus, (2) the age structure and (3) the sex ratio of hemiparasite in the selected area. Furthermore, (4) the assessment of the relationship between the age structure and weather in individual years. Location Pouzdřanská step was chosen for this purposeas on the relatively small area 6 species of oak and yellow mistletoe are growing. The age and sex of the individual hemiparasites was assessed either directly from the ground or climbing up to the crown. It was found that all investigated species of the genus Quercus are infested by yellow mistletoe. The most infested oak species are Quercus petrea, Quercus polycarpa a Quercus robur. The oldest yellow mistletoe individual was 21 years old and grew on Quercus pubescens. There were more frequent males individual. There was not found any apparent relationship between the history of weather and attachment of the yellow mistletoe to the host.
