Welcome to PATrees, a place to learn about Pennsylvania's trees, how to care for them and tap into expertise from across the Commonwealth.

Trees are an important part of Pennsylvania's landscape and history, providing a wealth of benefits to residents and visitors of the Commonwealth.  It's right in our name.  Pennsylvania or " Penns Woods" was named for its founder, William Penn who found a densely wooded landscape and proposed that 1 acre of forest be saved for every 4 acres cleared for farming.  Presently, nearly 60% or 17 million acres of Pennsylvania are forested.

Whether it be a large tracted of forest land, a small wooded homesite, a backyard shade tree, or a row of street trees, they all provide benefits such as beauty, shade, color, wildlife habitat, clean water and air, and increased property values.
