Performance of Urban Street Trees Evaluated

Abstract

Street tree plantings in Philadelphia, Pa. were evaluated 14 years after planting. Measurements of dbh, height, and crown diameter as well as foliage condition were used as an indication of adaptability to urban growing conditions. Of the 1 5 species rated, Kwanzan oriental cherry, black locust, Chinese elm, Japanese pagoda tree, ginkgo, and English oak were the most successful, both in terms of growth rates and overall freedom from insects and disease.
