Environmental Benefits
- Through photosynthesis, trees absorb carbon dioxide and emit oxygen. On average, an individual tree can absorb up to 48 pounds of carbon dioxide annually.
- Trees intercept small particulate matter (PM10) (e.g. dust, ash, pollen, smoke). This means trees are particularly valuable along the Wasatch Front and other areas in Utah that struggle with ozone and particulate matter pollution.
- Evapotranspiration from tree leaves turns liquid water to water vapor, thus cooling the air.
- During a storm, the canopy and root systems of trees act as both a sponge and a filter, which cleans the water as it seeps into the water table and reduces stormwater runoff.
- Tree roots speed up the rate at which rainfall infiltrates soil and increase the land’s water storage capacity, which reduces flooding and soil erosion.
- Trees provide habitat and food for wildlife, both in natural areas and urban spaces.
- Trees reduce the need for heating and cooling, thus decreasing the need for more power plants in the future.
Social Benefits
- Studies show that neighborhoods with significant greenery report fewer instances of crime.
- Drivers tend drive slower on roads lined by trees.
- Trees create a buffer zone between streets and sidewalks, creating a safer environment for joggers, pedestrians, and children at play.
- A community tree planting instills a sense of civic pride and a stronger connection to place.
- Outdoor spaces with trees are used significantly more than those without, facilitating interaction among neighbors.
- Trees have been shown to increase levels of concentration in children as well as higher test scores.
- People suffering from high stress tend to feel calmer in the presence of trees, thus improving overall health and well-being.
- Studies have shown that the performance of urban noise barriers is increased when used in combination with vegetative screens.
