Creating Canopy is Penn’s annual tree giveaway, designed to encourage the continual greening of urban areas in Greater Philadelphia. In partnership with TreePhilly and the Morris Arboretum & Gardens, Penn Sustainability staff and volunteers on May 9 distributed 150 free trees to staff and faculty of the University of Pennsylvania and the University of Pennsylvania Hospital System. Trees are beneficial in urban areas, since along with green roofs and other vegetation, they can help reduce urban heat island effects by shading building surfaces, deflecting radiation from the sun, and releasing moisture into the atmosphere. Since the first Creating Canopy event in 2011, Penn has distributed more than 2,500 trees.
