Urban forestry is the management of trees in urban spaces, providing benefits such as air purification and cooling. Trees must be carefully managed to thrive in harsh environments, and urban planners, policymakers, and arborists are involved in this field.
Forestry is the science of managing forests, planting trees and related natural resources. Some people consider it as much an art as a science. Urban forestry is the management of trees within urban spaces. Many cities have green spaces such as small parks or tree-lined areas lining streets, recreation areas, and monuments. Urban forestry is a type of forestry that focuses on the location and maintenance of such trees. There are many types of people who participate in, support or help plan urban forestry. These people include urban planners, environmental policy makers, and arborists.
Since tree populations in urban landscapes are exposed to very different elements from those found in nature, it is important that they are carefully managed and cared for. Also, people who focus on the importance of urban forestry are often interested in how trees improve their surroundings as much as how trees should be protected within their surroundings.
Trees can provide many benefits within urban areas. First of all, it is known that trees and other plants are excellent for cleaning and freshening the air. The air in urban areas, which is often tinged with emissions from vehicles and factories to name but a few pollutants, can be greatly improved by the presence of trees. In addition, trees and plants help to naturally cool the air and the earth. This can be a big plus. Cities generally consist primarily of steel, concrete, asphalt, and glass that reflect and conduct heat. Trees can help make cities in hot climates and cities in climates with hot summers much more bearable during hot seasons.
Because cities can be such harsh environments, the trees planted in them need to be looked after or else they may wither and die. One of the key elements in urban forestry is to ensure that trees in urban spaces are planted in soil of acceptable quality and have sufficient room for their root system to grow. Just as trees need to have enough room for their roots to grow, they also need to have enough room for their canopies. This means that trees must have enough overhead space so that their branches can spread out and get the sunlight they need to thrive.
While those who practice urban forestry certainly have many challenges ahead, it is clear that the challenges are worth the rewards. Trees and plants in urban spaces are wonderful environmental investments.
