UAH celebrates Tree Campus USA® recognition
UAH celebrates Tree Campus USA® recognition

UAH celebrated receiving Tree Campus USA® recognition today with a short ceremony that included James Bolte, President of Toyota Manufacturing, Alabama, Inc.; Jen Svendsen, Tree Campus USA Project Manager for the Arbor Day Foundation; Denise Taylor, Coordinator of Huntsville's Operation Green Team; and Clifford Hawkins, Coordinator of the state's Urban & Community Forestry Program, who presented a recognition plaque to UAH President Dr. Robert Altenkirch. The event was a component of the Tree Campus USA program, which is funded by Toyota and administered by the non-profit Arbor Day Foundation.

In his remarks to the audience, Dr. Altenkirch noted the university's ongoing commitment to sustainability through a variety of initiatives. "UAH has a rich tree canopy that we work to enhance annually," he said. "The effort is part of our overall efforts in sustainability from LEED certification to developing pedestrian-friendly pathways such as the greenway to the campus bike-sharing program. Many of these efforts are coordinated through Chargers for Sustainability, a network of organizations and individuals at UAH focused on bettering campus sustainability."
