SUMMARY: This paper presents research regarding the mutual relationship
between intra-seasonal variations of tree stem diameter changes,
changes of electrical resistance of cambial zone (ERCZ) and groundwater
oscillations. Two groups consisting of ten common oak fQuercus robur L.)
trees were selected, one group with crown damage status above (healthy
trees) and the other below 40 % (damaged trees). Research was undertaken in
the Pokupsko Basin area. The site was selected in forest type of pedunculate
oak and common hornbeam, the soil was gleic luvisol. The groundwater
regime on the site is characteristic for the wider area of the Posavina region
with high groundwater levels during the winter and spring seasons and low
levels in summer and autumn with minimal groundwater levels below 5 m.
