Megjegyzések:The structure of an Quercetum petraeae-cerris oak forest ecosystem within the Síkfőkút research area ("Síkfőkút Project") was examined by Authors already 35 years ago. The influence of the changes in stand structure due to the decline of sessile oak. The meso- and thermofil shrub species could be able to gain strength. The researchers registered the most important structural parameters of shrub layer in an "A" quadrat (48x48 m) of the oak-forest. The shrub heights were measured with a 3 m long yardstick and the diameter of shrub trunks were measured at 5 cm height above the soil with a slide gauge. Sixteen species were registered in the sample area in the both measuring in 1997 and in 2002. The number of shrubs individuals were 77083 pieces and 23874 pieces per hectar, more then 94,77% and 83,52% lived in the low shrub layer and only 5,23% and 16,48% lived in the high shrub layer. Euonymus verrucosus dominated in the low shrub layer some 46,0% and more then 50,0% on latter measuring. Acer campestre and Euonymus verrucosus came out at some 50,0% in the high shrub layer in both years. The two most frequently occuring high shrubs were Acer campestre and Euonymus verrucosus. The dominant shrubs grew bigger and bigger (the procession is taking at the moment), but the size of the others species decreased in a small compass. The rate of the low shrubs were decreasing as the latest measurement, proved.
