Enhancing
our Environment
Plants help protect water quality. The right
kind of landscaping reduces nitrate leaching from the soil into the water
supply. Plants also help reduce "surface water runoff", keeping
pollutants out of our waterways and preventing overload of the septic
system.
Plants
improve air quality. Landscape plats, including turf and shrubs,
remove dust, and smoke from the air. One tree can remove as much as 26
pounds of carbon dioxide from the atmosphere every year. One study showed
that 1 acre of trees has the ability to remove up to 13 tons of gases
and particles every year.
Landscaping
helps lower summer air temperatures. Trees shading homes can help
reduce attic temperatures as much as 40 degrees. According to the EPA,
urban forests reduce urban air temperatures by shading heat sinks such
as concrete and buildings, and returning humidity to the air through evaporative
cooling.
Landscaping
can reduce soil erosion. A thick cover of plants and mulch
holds soil in place, keeping sediment out of streams, lakes, roads, and
storm drains; and reducing mudslides and flooding.
Landscaping
conserves natural resources. Properly placed deciduous trees reduce
house temperatures in the summertime, thus allowing air conditioning units
to run 2 to 4 percent more efficiently, but also allows the sun
to warm the home in winter. Home sheltered by evergreen windbreaks can
reduce winter heat loss and are generally warmer than homes without such
protection. By using trees to modify temperatures and protect against
wind, the amount of fossil fuels used for cooling and heating is reduced.
Landscaping
helps screen busy streets and intersections. Properly placed plantings
offer more privacy by screening out busy noises and reducing glare from
headlights.
