We are all aware of the common benefits such as beauty, shade, wildlife habitat,
and oxygen production that trees provide us, but did you know that trees
-
Reduce annual heating and cooling costs for a typical residence by 8-12%
-
Improve air quality by absorbing hundreds of pounds of air pollutants that effect
our health
-
Improve water quality and reduce community flooding by absorbing and intercepting
rainfall in their canopies, thus reducing stormwater that often carries pollutants
to waterways
-
Stimulate retail and commercial business districts by attracting shoppers, increasing
sales and revitalizing declining downtowns
-
Increase property values by 10-15% (one study in Kensington area of Philadelphia
showed a 9% increase, or $3,400 from the presence of a newly planted tree with 50
feet of the house)
-
Reduce stress, fatigue, and aggression in humans
-
Reduce a hospital patient’s recovery time when there are views of trees and greenery
-
Improve the concentration of children with Attention Deficit Hyperactivity Disorder
(ADHD)
-
Calm and slow down traffic along streets
-
Reduce crime and increase social ties
- Reduce exposure to harmful UV rays that are causing increases in skin cancer and
cataracts
