Abstract
The process of oak decline, typical in the last century has periodically or occasionally reappeared in most of European countries. Several theories are trying to explaining the decline as the combined effects of several factors: primary factors which should be taken into consideration are abiotic and secondary ones antropogenic and biotic factors.
If the reason for the decline of forests in the 70’s and 80’s was air pollution, the researches are not sure about the primary causes of recent »new age« forest decline, where the symptoms are similar to those in air pollution, but geographical range of decline is much wider.
There is not only single factor causing the decline of oaks. The complex of interactions among factors is specific to the environment; from the pathogenic point of view it is very difficult to insulate one specific cause when climatic stress, industrial pollution and management mistakes from the past are present. It is important to define the main factor in every case and study the physiology of weakening process.
The decline of oaks in Slovenia, especially of penduculate oak (Quercus robur L.), is most evident in lowland forests the north-east of Slovenia. The most likely reason could be dryer climate, unfavourable precipitation distribution and hydromelioriation. Especially older and mature oaks are in worse condition what confirmed an annual crown defoliation inventory on permanent research plots in wider area of Murska šuma forest complex and over Slovenia.
In this study we would like to study penduculate oak stand in Murska šuma forest complex in the north-east of Slovenia. There is a urgent need to evaluate the degree of water stress, interaction relation between water table - forest soil - tree, and to define the main factor in the process of oak decline in this region. We would also study site conditions, phytopathology and management history of oak forests in the Murska šuma forest complex.
