What’s a tree worth?
In what has become an annual tradition, students in Creating the Urban Eden: Woody Plant Selection, Design, and Landscape Establishment (HORT/LA 4910/4920) are helping to make people more aware of why trees are worth hugging by hanging bright green “price tags” on trunks around the Ag Quad.
The students entered data about the trees, such as species, diameter and location, into i-Tree — a state-of-the-art, peer-reviewed software suite from the USDA Forest Service. The application then calculates monetary benefits from reduced stormwater runoff, improved air quality, carbon dioxide sequestration and energy savings to nearby buildings by blocking wind in winter and providing shade in summer.
“It’s really quite eye-opening for people who think that trees are just nice to look at and don’t have any other value,” said Nina Bassuk, professor in the Horticulture Section of the School of Integrative Plant Science, who leads the class alongside Peter Trowbridge, professor in the Department of Landscape Architecture.
There are also benefits that are not easily quantified, such as wildlife habitats and emotional responses, added Bassuk, who is also director of the Urban Horticulture Institute.
