The Importance of Diversity in Selecting Trees for Urban Areas    (View PDF)

A.G. Endress

Abstract: The ability of trees to cleanse the air of pollutants, capture and store carbon dioxide as a buffer against the greenhouse effect, and air condition the buildings in which we live and the outdoor spaces we use has become the focal point for several vigorous campaigns to reforest America as a positive step to redress several concerns about the environment. Reforestation is much needed, but its occurence in a helter-skelter manner should be avoided. A long-term reforestation plan is needed based on (1) the selection of a broad range of plant materials with respect to biologic/genetic diversity and the specific characteristics of the planting sites and (2) the organization, scope, and technical support of tree care delivery systems. Furthermore, there is a critical need to promote arboriculture as a rewarding career so that new students and trainees are attracted.
