Trees and shrubs alter the environment in which we live by moderating climate, improving air quality, conserving water, and harboring wildlife.
The more compact the foliage on the tree or group of trees, the greater the influence of windbreak. The rain, sleet, and hail is initially absorbed or deflected by trees, which provides some protection for people, pets, and buildings. Trees intercept water, store some of it, and reduce storm runoff and the possibility of flooding.
By planting trees and shrubs, we return to a more natural, less artificial environment. Birds and other wildlife are attracted to the area. The natural cycles of plant growth, reproduction, and decomposition are again present, both above and below ground. Natural harmony is restored to the urban environment.
Air quality can be improved by the presence of trees, shrubs, and turf. Leaves filter the air we breathe by trapping dust and other pollutants.
