Stormwater Management Benefits of Trees

The benefits of trees as stormwater management practices, especially in urban and suburban settings, have recently been more widely recognized.

Three primary processes—interception, transpiration, and infiltration—can reduce the amount of rain falling on trees that becomes stormwater runoff.  Pollutant removal is another important function performed both by trees and by the soils they grow in.
