A Living Campus
Tree Pittsburgh’s campus, including the arboretum, is an educational one. It’s a living demonstration of the power of trees to enhance and revitalize landscapes and waterways.
As you walk our arboretum and trail, you’ll see plants and trees of all kinds, some that have been there for decades and some that were selected specifically for our conditions. Keep your eyes open for wildlife, including a bald eagle and our resident spiny softshell turtle Myrtle.
