Sulfur dioxide, nitrogen oxides, carbon monoxide, chlorine, fluorine, and ozone are the leading air pollutants that injure tree and shrub foliage in the Tennessee urban landscape. A single tree, depending on species and the genetic (cultivar), may respond differently to particulate and gaseous pollutants. The stage of growth and how close it is growing near the source of the pollution may determine the degree of foliar injury in the tree.<\/p>\n
In addition, urban trees are exposed to other environmental stresses such as soil compaction, toxic salts, disease and insect pests. Environmental stresses may develop foliar injury symptoms which appear very similar to those of air pollution.<\/p>\n
The following tree species are best adapted to the urban environment:<\/p>\n
