Trees use carbon dioxide when they grow,  removing it from the air. 

A treed environment can reduce blood pressure, increase patient recovery time, and reduce stress.

Mature trees intercept rainfall, reducing runoff and providing cleaner water. Thanks to this benefit, heavy metals and other pollutants from roads, parking lots, and roofs are not carried into our water supply.

Trees provide shelter and food for a variety of birds and small animals. They interact with other living things in sharing and recycling resources.

Tree roots hold soil in place reducing erosion and runoff. Nearly 11,000 tons of soil are saved annually with tree cover in a medium-sized city.

A tree shading a home air conditioner has been estimated to improve its efficiency by 10%. Evaporation from tree leaves cools the air resulting in further reduction of summer air conditioning costs. 

Patrons linger longer and make more frequent trips to venues along tree-shaded avenues. Businesses leasing office space in wooded developments find their workers are more productive!

The value of houses on lots with trees is often higher than those of comparable houses on lots without trees. Each large front yard tree adds 1% to the sale price. These homes rent more quickly, have higher occupancy rates, and provide privacy for residents.

Residents who live near urban trees have better relations and stronger ties to their neighbors. In addition, tree planting programs teach local stakeholders about their local environment!

Trees provide “white noise," the noise of the leaves and branches in the wind and associated natural sounds, that mask other man-caused sounds.

One acre of trees generates enough oxygen per day for 18 people to breathe. Trees absorb gaseous pollutants and filter particulates. Trees lower local air temperatures by transpiring water and shading surfaces.

Recreation areas with lush urban forests such as parks, greenways, and river corridors attract newcomers and provide areas of play.
