See these links for more information about the benefits of trees!

The benefits of trees include:

• Trees increase real estate values of both commercial and residential property.
• Trees create a pleasing environment in which people are inclined to shop more often, for longer periods of time, and to spend in the range of 11% more for the same product than if it was sold in a treeless business district.
• Trees can reduce ambient noise levels by about half.
• Trees, when properly sited to block cold winter winds and the hot summer sun, can reduce energy bills by as much as 40%. (Vancouver Urban Forestry Commission)
• Trees clean the air by removing dust and other particles, and absorbing pollutants such as ozone, carbon monoxide and sulfur dioxide.
• Trees absorb carbon dioxide and release oxygen. The oxygen that one person needs to breathe for a year is produced, on average, by two healthy, mature trees annually.
• Trees reduce glare and reflection off road surfaces, as well as shading and cooling those surfaces and thereby reducing the "heat island" effect.
• Trees provide wildlife habitat.
• Trees reduce erosion and the danger of flooding by holding soil with their roots and slowing the force and pace at which rain strikes the earth.
• Trees have an important role in salmon recovery, both when they are planted near streams and away from them. They shade and clean water, as well as slow the force with which it enters streams.
• Trees are beautiful. They soften the hard edges of buildings and streets, making the city a more pleasant place to be for residents and tourists alike.
• Trees can screen unwanted views, create privacy, and give a space a sense of place.
• Trees are also good for people's psyches. Hospital patients recover faster when they have a view of trees (ISA). Big, strong, old trees have a reassuring sense of endurance. Studies have shown that brief encounters with nature can improve people's capacity to concentrate. Another study found that people who saw nature regularly during their workday reported higher job and life satisfaction and less illness than those who didn't.

In short, trees just make life more pleasant.

However, the wrong tree in the wrong place can create more problems than it solves. It's important to choose the location and species of your trees carefully, and to keep them maintained correctly, so that they can provide the maximum benefits to you and all the members of the urban forest.
