| Abstract: |
Trees are the new technology to retain water on site, some permanently, some temporarily, to slow the flow to waterways. Trees protect water and soil resources. Healthy trees can reduce the amount of runoff and pollutants in creeks, ponds and other receiving waters in three primary ways: leaves, branch surfaces, and trunk bark intercept and store rainfall, thereby reducing runoff volumes and delaying the onset of peak flows; root growth and decomposition increase the capacity and rate of soil infiltration by rainfall and reduce overland flow; and tree canopies reduce soil erosion by diminishing the impact of raindrops on barren surfaces. |
