Megjegyzések:	Shrub layer dynamics is an indicator of forest health and it is also linked to ecological functioning of the forest. Similarly to other European countries there was an oak decline at the end of 70's in Hungary. At the Síkfőkút Project area 68.4% of the Quercus petraea and 15.6% of the Quercus cerris tree specimens died during the oak decline. In this paper we are exploring the dynamics of shrub layer after the decline. Location and cover of shrubs were mapped in a 48 m?48 m plot; the height and the diameter of each shoot were recorded in 1972, 1982, 1988, 1993, 1997, 2002 and 2007. Location (1972) and cover (1974) of trees were also mapped. We found that after the oak decline a secondary tree layer was formed by three shrub species (so-called dominant shrubs: A. campestre, Cornus mas and A. tataricum). There were 20 shrub species in the study area. In the gaps the density of Euonymus verrucosus increased remarkably, but they never grow up higher than 4.0 m. The secondary tree specimens showed clustered distribution in every measuring. We found no correlation between oak tree density and the total shrub cover, and surprisingly we found a positive relationship between oak tree density and dominant shrub's density. Our study revealed that the forest responded to the tree decline by structural changes in both tree and shrub layer.
