Abstract During the last decade, typical symptoms of Phytophthora diseases were observed in beech stands of several European countries (Jung et al., 2005). The main symptoms are the presence of bleeding cankers on the stem (fig. 1), a low crown density (fig. 2) as well as the yellowing of foliage and the small size of leaves. Several species of Phytophthora, such as Phytophthora citricola, P. cambivora and P. cactorum, were reported as the causal agents. In order to evaluate the involvement of the different Phytophthora species in beech decline in the southern part of Belgium (Wallonia), a survey was undertaken with the help of managers of public and private forests (Schmitz et al., 2006). This study also contributes to the monitoring of the appeareance of new Phytophthora species in forests of Wallonia.
