National Arbor Day

National Arbor Day.

In Spring 2023, Yale University proudly garnered Tree Campus Higher Education recognition from the National Arbor Day Foundation. Together with over 500 volunteer tree-planting hours from students, alumni, faculty, and staff, this honor is the result of a nine-year collaborative effort of a core group of staff members from the Office of Sustainability, Facilities, Office of Public Affairs and Communications, and the Urban Resources Initiative at the School of the Environment. Our campus joins 411 university and college campuses across the U.S. in meeting five vigorous standards that include an annual campus-wide celebration to enhance learning about the benefits of trees.

When it comes to celebrating National Arbor Day at Yale, all are invited to participate and there’s something for everyone. Check out a few of the ideas below and be sure to give your favorite tree a hug!
