So, what is the urban forest that is at the heart of what we call urban forestry?

The answer to this question is an important one. First, it sets the parameters of what might fall under the stewardship of tree boards and municipal forestry departments. This, in turn, has taken on far more importance in recent years as scientists have quantified the ecoservices provided by the greenery in our communities. These significant contributions include cleaner air and water, energy savings, asphalt surface protection, crime reduction, mental health benefits, and more. 

In smaller communities, some are troubled by the word “urban.” This concern has been circumvented by adoption of the word “community” in its place. Sometimes the usage is “urban and community.” The concepts are the same, and the usage is simply a matter of community size and preference. In this issue, we use “urban forest” as a matter of convenience. 

There are an estimated 5.5 billion trees in the urban forests of the United States, providing a value of more than $2.4 trillion in environmental services and other benefits. About 80–85% of the trees are on private property, and the rest are found along streets, in parks, and around large buildings or on campuses. All comprise the urban forest and all contribute not only to their owners or managers but to society as a whole.
