in tree alley in Zagrebačka street. Highest percent share of given symptoms and tree defects at old horse chestnuts trees was assessed in Zagrebačka street and near the railway station while smaller percent share was recorded in park. Visual tree assessment with resistography revealed two of older trees which need to be removed due to their mechanical breakdown resulting with heightened risk on humans and property. Dendrochronological analysis revealed sensibility in radial increment of measured trees (0.08–8.17 mm). Significant positive correlation of radial increment with average spring precipitation and limiting effect of maximum spring air temperatures was determined.
