Abstract: Nine tree species in four central New Jersey communities were studied to determine the relationship of site factors with the growth of trees in urban areas. The four site variables included: house setback from the road; the presence of competing vegetation; the width of the tree lawn; and the amount of permeable surface beneath the tree crown, Tree growth was measured using a growth ratio index, the ratio of DBH to age for a given tree. The results indicated that although for several species there is a significant linear relationship between growth ratio index and these site factors, the R2 values for the nine species ranged between less than 0.01 and 0.14, indicating that a maximum of 14% of the variation in growth of these species can be explained by the linear models chosen.
