Tree ring width and health status of the red oak (Quercus rubra L.) under urban conditions in Szczecin (NW Poland)

Cedro, Anna; Nowak, Grzegorz

Abstract

Dendrochronology of the red oak (Quercus rubra L.) was studied based on tree ring width analysis of trees growing under urban conditions in a tree-lined street and in a park in Szczecin, Poland. The chronologies developed, 78- and 87-years-long, respectively, were analysed, in terms of signature years and correlation and response functions, by following the tree ring width vs. climate relationships. The red oak tree ring width proved to be primarily controlled by atmospheric precipitation, particularly in February and June. Wide rings were produced by high annual precipitation totals and a sufficiently large precipitation in the summer months.
