New Elm trees planted on the North Central Green on the University of Delaware main campus. Replacing trees which were removed during maintenance work on the service lines beneath the ground, the selection of Elms refers back to the original "Delaware College at Newark" design by famed landscape designer Marian Cruger Coffin. - (Evan Krape / University of Delaware)

Trees for Delaware

Trees are important to people. Research shows that access to nature plays a significant role in life satisfaction. The most preferred scenes are ones in which nature is dominant, where there is a smooth ground texture and where trees help define the depth of the scene. Patients recover more quickly when the view from their hospital window includes trees, and trees in apartment courtyards promote social interaction.

Trees also improve the physical environment. They improve air quality by trapping dust particles and replenishing oxygen. Trees save energy by cooling during summer and providing wind breaks in winter. Trees can reduce air conditioning needs by 30 percent and save 20 to 50 percent on fuel costs for heating. Trees improve water quality by reducing the impact of raindrops—resulting in less runoff and erosion. Trees provide habitat for animals and birds add beauty to the environment and soften the harsh lines of the urban and suburban world. Ecosystem refers to all of the organisms in a given place (including people) and their interactions with each other and the environment. Ecosystem-based management is new to urban and community forestry, shifting the focus from individual street trees to entire communities. With an ecosystem-based management approach, we can appreciate how trees reduce storm water runoff.
