Landscape Architecture Magazine, April Excerpt: For now, only you can keep trees with ill-formed roots from leaving the nursery.
Contact Benefits of Trees Urban Releaf is not just about beautifying the streets and giving life to under-served communities. Every tree that takes root also carries with it a myriad of benefits to our health, quality of life, and well-being — locally and globally.
Air Quality Urban forests intercept and absorb air pollution from the atmosphere.
The major air pollutants are sulfur dioxide, SO2nitrogen oxides NO2ozone O3and fine particulate matter such as soot, dust, pollen, and emissions from diesel vehicles.
Trees also reduce air pollutants i. Large, healthy trees can remove more than 70 times more pollution than small trees. Maximal urban forest carbon sequestration benefits in cities can be attained by choosing to plant tree species that grow to be large, placing them in a good growing site and condition, and keeping them strong and healthy.
Trees lower air temperatures making urban areas more inhabitable for humans and wildlife. Urban forests help reduce global warming by absorbing sequestering and storing carbon dioxide CO2 from the atmosphere.
Urban Heat Island Effect Cities are on average 1. This increased heat in cities can cause health problems including general discomfort, respiratory difficulties, heat cramps, heat exhaustion, heat stroke and even death.
Dark, rock-like materials like concrete and asphalt that roads and buildings are made with absorb high levels of energy from the sun.

Sunlight is absorbed by these materials which radiate heat into the surrounding air and buildings, warming the temperature, contributing to the urban heat island effect.
Green spaces help offset the formation of urban heat islands by cooling the regional micro-climate through shading and evapotranspiration, thusly reducing the energy needed to cool buildings during hot periods.
In addition, trees planted as wind shields can significantly reduce heating costs for buildings during the winter. Planting trees more than other kinds of vegetation is the best way to combat urban heat islands because trees have a higher potential to cool the climate and reduce the urban heat island effect and carbon dioxide CO2.
Using lighter color materials reflect sunlight preventing extremes of the urban heat island effect. Water Quality The Bay area, inclusive of Oakland, is surrounded by a network of waterways, while businesses and residential districts sit on erosion-prone hills.
West Oakland in particular lies between numerous plants, refineries, and interstate highways. This combination of pollutant production and a delicate urban landscape demontrates a clear threat to our natural environment.
Trees can perform a multitude of environmental, social, and economic services. Water quality and flow, for example, can be dramatically improved by planting, not just trees, but the right trees. By matching specific tree species to sites, trees can fulfill particular functions in the landscape.
In urban settings, trees can reduce the amount of runoff and pollutant loading. In fact, mature trees catch aboutgallons of rainwater per year decreasing flood risk as well as soil and hill erosion. Tree leaves and roots naturally filter water and remove pollutants.
Trees help store water: Trees help water soak into the ground and recharge water tables. Trees promote cleaner waterways: Trees absorb sediment, nutrients and chemicals before they enter streams and other bodies of water.
Trees reduce soil erosion and flooding by slowing the movement of storm water. Our work has shown that areas with greener surroundings draw residents to interact with nature, for adults to socialize, and children to play outside.
Playing in forested urban areas also helps children develop social skills and cognitive abilities, improves school performance and concentration, and reduces symptoms of Attention Deficit and Hyperactivity Disorder ADHD Taylor et al.
Views of trees from the home give residents a greater sense of well-being and satisfaction with their surroundings. Urban residents living in greener areas build strong feelings of belonging and attachment to their neighborhood, and the trees that comprise their neighborhood.
Active participation in urban forestry provides: Urban forests are associated with residents feeling safer, communities with reduced crime and fewer social incivilities. Active participation in urban forestry planning, planting, and stewardship is an empowering experience for individuals and the community as it directly improves the environment, help developing skills, and builds ties with others in the urban forestry community.
As trees grow they increase in their ability to provide comprehensive and holistic benefits for communities. Spirituality and Psychology People who were shown images of nature demonstrated decreased heart rates and blood pressure, and overall reduced stress.
In a Chicago study, areas with better landscaping and trees had fewer instances of domestic abuse, less crime, and stronger relationships among neighbors Kuo and Sullivan; Hines.
In related research conducted by Moore in prisons, inmates with exterior cells who enjoyed farmland views versus those with interior ones requested healthcare services less frequently. People even tend to drive more slowly on tree-lined streets, positively influencing driver behavior.Urban forestry is the care and management of single trees and tree populations in urban settings for the purpose of improving the urban environment.
Urban forestry advocates the role of trees as a critical part of the urban infrastructure. Georgia Urban Forest Council Sustaining Georgia's green legacy by partnering with individuals, organizations, and communities in raising awareness toward improving and maintaining Georgia's community forests.
