Environmental Impact:
Landscaping can
reduce air-conditioning costs by up to 50% by shading the
windows and walls of a home. (Source American Public Power Association.)
Trees can
reduce bothersome noise by up to 50% and can mask unwanted noises
with pleasant sounds. (Source: US Environmental Protection
Agency.)
Trees can
reduce temperatures by as much as 9 degrees Fahrenheit.

Plants protect
water quality. Proper landscaping reduces nitrate leaching
from the soil into the water supply. Plants also reduce
surface runoff, keeping phosphorus and other pollutants out of waterways.
Reduction of soil
erosion. Soil covered with plants and mulch holds soil in place,
keeping sediment out of streams, lakes, storm drains, ponds, and
improves water quality.
Improving air
quality. One tree can remove 26 pounds of carbon dioxide
from the atmosphere annually, equaling the amount of carbon
dioxide produced by driving 11,000 miles. Landscape plants and
turf also remove smoke, dust, and other pollutants from the air.
Air
temperatures. Based on EPA studies, urban forests reduce air
temperatures significantly by shading buildings, concrete, and
asphalt, as well as returning humidity to the air. Trees shading
your home can reduce attic temperatures as much as 40 degrees. |
