General Facts About Trees

• Trees keep our air supply fresh by absorbing corbon dioxide and producing oxygen.
• In one year, an acre of trees can absorb as much carbon as is produced by a car driven up to 8700 miles.
• Trees provide shade and shelter, reducing yearly heating and cooling costs by 2.1 billion dollars.
• Trees lower air temperature by evaporating water in their leaves.
• The average tree in metropolitan area survives only about 8 years!
• A tree does not reach its most productive stage of carbon storage for about 10 years.
• Trees cut down noise pollution by acting as sound barriers.
• Tree roots stabilize the soil and prevent erosion.
• Trees improve water quality by slowing and filtering rain water as well as protecting aquifers and watersheds.
• Trees provide protection from downward fall of rain, sleet, and hail as well as reduce storm run-off and the possibility of flooding.
• Trees provide food and shelter for wildlife.
• Trees located along streets act as a glare and reflection control.
• The death of one 70-year old tree would return over three tons of carbon to the atmosphere.

Trees and the Environment

• Trees renew our air supply by absorbing carbon dioxide and producing oxygen.
• The amount of oxygen produced by an acre of trees per year equals the amount consumed by 18 people annually.  One tree produces nearly 260 pounds of oxygen each year.
• One acre of trees removes up to 2.6 tons of carbon dioxide each year.
• Shade trees can make buildings up to 20 degrees cooler in the summer.
• Trees lower air temperature by evaporating water in their leaves.
• Tree roots stabilize soil and prevent erosion.
• Trees improve water quality by slowing and filtering rain water, as well as protecting aquifers and watersheds.
• The cottonwood tree seed is the seed that stays in flight the longest.  The tiny seed is surrounded by ultra-light, white fluff hairs that can carry it on the air for several days.
