摘要

This paper evaluates the possibility of determining tree age based on diameter at breast height (dbh, taken at 1.3 m), using common lime (linden, Tilia cordata). The field measurements were made in Warsaw and in selected locations in the Mazowsze (Mazovia) region, Poland. We first identified and measure groups of trees growing in similar conditions (alleys and roadside trees) whose age was known. We developed a regression model describing the growth of trees over time. Plotting tree age against diameter yielded a correlation coefficient of r=0.962 and determination coefficient of r2=0.926. The resulting model was applied to unrelated groups of trees of known age. The difference between the actual age and mean age calculated with the model was less than 10%. The model was then compared to measurements taken with a resistograph, with results being highly concordant. The model, although not meant for application to individual trees, might be useful in determining the age of common lime trees growing in alleys and along roads..
