Urban and community trees have an important role in mitigating climate change and helping cities adapt to higher temperatures and other impacts of climate change. Like forest trees, urban trees reduce greenhouse gases by sequestering carbon dioxide, and control soil erosion and runoff from heavier rain events. When placed properly, they can reduce the amount of energy needed to heat and cool buildings. These “ecosystem services” can be quantified at the individual tree, city or even state level. Community trees also soften the harsh angles of urban landscapes and ameliorate noise, providing psychological relief in an increasingly urbanized world. They are a symbol of nature, creating recreational space as well as wildlife and plant diversity in urban environments. Their ecosystem services go far beyond that which is quantifiable.
