| Title : | LONG-TERM EFFECTS OF OAK DECLINE ON SHRUB INDIVIDUAL’S OCCURRENCES IN AN HUNGARIAN OAK FOREST |
| Abstract : | Information about the occurrence of shrubby individual’s relation with oak decline is fundamental to developing knowledge from forest stand. This paper focuses on the following questions: (1) how are the shrub’s occurrences changed after oak decline? (2) Which shrubs have the highest occurring in the subplots? The mixed oak stand is located in the Bükk Mountains of Hungary. The monitoring plot (48 m × 48 m) was subdivided into 144 permanent subplots; the measured parameter was observed in the period 1972-2017. The shrub layer was divided into low (< 1.0 m in height) and high (≥ 1.0 m) layer. High shrub specimens were randomly distributed and had become more homogeneous by 2017; there was no subplot with 10 or more specimens in the last decade. In the subplots the policormon forming shrubs were present with a higher occurrence. Correlation analysis showed that occurrence of Acer tataricum, Cornus mas and Euonymus verrucosus in the high and Cornus sanguinea and Ligustrum vulgare in the low shrub layer changed significantly after the oak decline. High shrubs with the highest occurrence were E. verrucosus and C. mas. The most occurrent low shrub species were E. verrucosus and L. vulgare. Our results suggest that after the oak decline the most shrubs’ occurrence decreased considerably and the distribution was more homogeneous. |
