At the Síkfőkút Project Long Term Ecological Research (LTER) area covered by a sessile oak – Turkey-oak forest (Quercetum petraeae-cerris). Similarly to other European countries an oak decline occurred in Hungary at the end of 1970’s. The oak decline resulted in an opening of the canopy; the canopy cover decreased from 80% (1972) to 36% (2007). The sparse canopy led to structural change of the understory resulting from changes in light and thermal regime. The aim of our study was to analyse the structural changes in the forest interior during 5 years period. Our hypotheses were the followings: (i) the density of low shrub species showed significantly changes. (ii) The high shrub specimens showed clustered distribution. The dominant species was Euonymus verrucosus in the low shrub layer and E. verrucosus and Acer campestre recorded as dominant species in the high shrub layer. According to the mean height the A. campestre and Acer tataricum were the biggest high shrub species. The low-and high shrub specimens showed clustered distribution in the plot. The forest responded to the serious tree decline by significant structural changes in the understory shrub layer.
