Tree planting provides a host of ecological, social, and economic benefits. Trees can intercept rain, support infiltration and water storage in soil, diminish the impact of raindrops on barren surfaces, minimize soil moisture through transpiration, and they help reduce stormwater runoff. Additionally, trees contribute to recharging local aquifers and improve the health of watershed systems. Trees also reduce energy usage by providing shade and releasing water into the atmosphere which cools the air and reduces the amount of heat absorbed by buildings. Finally, trees improve air quality by absorbing harmful air pollutants reducing the amount of greenhouse gases.
