Why we think EVERYONE should plant a tree

So you might sometimes hear us plant types talking a lot about ‘tree cover’ – and that a community should aim for over 40% tree cover to be a healthy outdoor living space. We have a LOT of opinion about this –  trees make us happy – trees make oxygen  – it is a pretty long list – and we thought these are some great ‘tree facts’ you can share with friends, family, and all who can impact trees. This is a great time to be planting trees – so get busy!

Trees improve health

Trees improve moods and emotions, and they create feelings of relaxation and well-being.

Trees provide 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.

Trees add natural character to our cities and towns


They 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.

Trees reduce pollution


Trees absorb carbon dioxide and other dangerous gases and, in turn, replenish the atmosphere with oxygen.

An acre of trees (about .4 hectares) 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 about 41,000 kilometers (26,000 miles).

A single mature tree can absorb about 21 kg (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 percent reduction in street-level particulate readings.

One 30 cm diameter (12-inch) sugar maple tree along a roadway removes 60 mg of cadmium, 140 mg of chromium, 820 mg of nickel, and 5,200 mg of lead from the environment each growing season.

Trees conserve water and prevent soil erosion


Trees reduce surface runoff from stormwater and prevent soil erosion and sedimentation of streams.

Trees increase groundwater recharge to help make up for losses in paved areas.

Trees prevent wind from eroding soil.

Trees 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 minimizes landscape heat load.

Shade trees can reduce air conditioning costs up to 30 percent.

Evergreens planted on the north sides of buildings can intercept and slow winter winds.

Trees increase economic stability


Trees enhance community economic stability by attracting businesses and tourists.

Healthy trees can add up to 20 percent to residential property values.
