The paper presents the results of the studies on the impact of climate conditions on the width of annual increments at the maidenhair tree, as well as on the distribution and age of trees of this species growing in Szczecin. The cataloguing of the trees and the following dendrometrical and dendrochronological analysed were made in the years 2004-2005. The chronology constructed on the basis of 11 individual sequences displaying the highest statistical similarities spans 112 years (1894-2005). The average width of annual increments for the analysed trees amounts to 1.9 mm, but the largest tree rings reached up to 8 mm. The analyses of meteorological conditions indicate, that the positive signature years are correlated with the years with high total rainfall, particularly in the period April-July. The air temperature has no significant impact on the width of annual increments.
