Benefits of Trees

Improve health
- Trees improve moods and emotions, and they create feelings of relaxation
and well-being.
- Trees probide privacy and a sense of security.
- Foliage helps to settle out, trap and hold particulate, pollutants
(dust, ash, pollen and smoke) that can damage human lungs.
- Because of their potential for long life, trees frequently are
planted as living memorials. We often become personally attached
to trees that we or those we love have planted.
- In cities, trees can act as buffers, absorbing a significant amount
of urban noise.
Add Natural Character to our cities and towns
- Provide us with colours, flowers, and beautiful shapes, forms
and textures.
- Trees add interest by changing with the seasons.
- Trees and associated plants create habitat and food for birds
and animals.
Reduce Pollution
- Trees absorb carbon dioxide and other dangerous gases and, in
turn, replenish the atmosphere with oxygen.
- An acre of trees produces enough breathing oxygen for 18 people
every day.
- An acre of trees absorbs enough carbon monoxide over a year's
time, to equal the amount you produce when you drive your car 26,000
miles.
- A single mature tree can absorb 48 pounds of carbon dioxide per
year, and release enough oxygen back into the atmosphere to support
two human beings.
- Over 50 years, a tree generates $31,250 worth of oxygen, provides
$62,000 worth of air pollution control, recycles $37,500 worth of
water, and controls $31,250 worth of soil erosion.
- City streets lined with trees show a 60 per cent reduction in
street-level particulate readings.
- One 12-inch sugar maple along a roadway removes 60mg of cadmium,
140mg of chromium, 820mg of nickel and 5,200 mg of lead from the
environment each growing season.
Conserve water and prevent soil erosion
- Trees reduce surface runoff from storm water, and prevent soil
erosion and sedimentation of streams.
- Trees increase ground water recharge to help make up to losses
in paved areas.
- Trees prevented wind from eroding soil.
Save energy
- Deciduous trees provide shade and block heat from the sun during
hotter months. By dropping their leaves in the fall they admit sunlight
in the winter.
- Shade from trees over hard surfaces such as driveways, patios
and sidewalks minimize landscape heat load.
- Shade trees can reduce air conditioning costs up to 30 per cent.
- Evergreens planted on the north sides of buildings can intercept
and slow winter winds.
Increase economic stability
- Trees enhance community economic stability by attracting businesses
and tourists.
- Healthy trees can add up to 20 per cent to residential property
values.
