The creation and care of urban forests are receiving greater attention as city populations grow larger. Recognizing this important trend, the U.S. Forest Service and the Morton Arboretum supported the development of these educational exercises designed to connect urban students with urban trees and forests. This Urban Forestry Unit was developed as a supplemental activity guide for elementary, middle, and high school students. The Unit’s “hands-on activities are designed to be data gathering exercises leading the student to make judgments based on analysis and synthesis of the gathered data.” The activities address the following topics: tree identification and inventory; tree characteristics; tree planting and care; tree condition, and soil conditions for trees. The website introduces the activities with brief sections that address the philosophy, objectives, and curriculum goals behind the project.
