Trees are valuable:
– According to the International Society of Arboriculture, a specimen shade tree may be worth up to $38 per square inch of the trunk cross-section. For example, a tree two feet in diameter could be worth as much as $17,176 or a three-foot tree up to $38,646 using the Trunk Formula method of valuation.
– Property values go up with trees. Real estate agents and homebuyers typically assign 10 to 23% of a residence’s value to the trees on the property.
Trees save energy in three ways:
– Shade. In a Miami study, the temperature of an unshaded west wall ranged from 112 to 117° F; a similar surface shaded by one large tree ranged from 87 to 92° F; a reduction of more than 20%. Shade also reduces heat reflected by concrete or asphalt surfaces.
– Natural “air conditioning.” Evaporation of moisture from leaves cools air under a tree’s canopy by 6 to 8° F. Trees can reduce daily air conditioning costs by as much as 50 percent.
– Reduced air infiltration. As windbreaks, trees can save up to 30% of winter heating bills.
Trees clean the air
Over a year’s time, one acre of growing trees will absorb all the carbon dioxide produced by an automobile driven 26,000 miles. Trees also trap and remove particulates from the air.
Trees help reduce stormwater runoff and soil erosion.
Trees make the neighborhood
They cut traffic noise, give a home to songbirds and small mammals, restore our health and spirits and make our community the place we want to live.
