A tree id tutorial and summer key to Pennsylvania trees developed by Penn State Natural Resources Extension

The trees of “Penn’s Woods” – the translation of our state’s Latin name – have supported people in what is now Pennsylvania for thousands of years. Trees are essential to our lives. They act as living filters, cleaning the air we breathe and the water we drink. They help heat our homes and cool our streets. They provide us flooring, cabinets, medicines, maple syrup, paper and countless other products. They are sources of the inspiration and beauty that help define Pennsylvania.
