The Pennsylvania Tree Resource Guide

Trees. They are an important part of Pennsylvania’s landscape and history, providing a wealth of benefits and ecological services to the residents and visitors of the Commonwealth. It’s right in our name – Pennsylvania means “Penn’s Woods” named for its founder William Penn. Nearly 60% (or 17 million acres) of Pennsylvania’s 28 million acres are forested.

Whether it a large tract of forested land, a small wooded homesite, a backyard shade tree, or a row of trees lining a community’s street, they all serve a purpose and provide benefits such as shade, color, beauty, wildlife habitat, clean water and air, and increase property values.

Tree Owners Manual Available from the Forest Service

One common issue facing our urban forests is the fact that trees are dying prematurely. Many are planted improperly, setting them up for failure. Many do not receive regular maintenance. And few are adequately protected during construction projects. To help remedy this issue, the Forest Service has created this Tree Owner’s Manual.
Just like the owner’s manual that comes with automobiles and appliances, the Tree Owner’s Manual includes a parts list, instructions for installation, tips for troubleshooting common issues, recommended service, and more.
