Pennsylvania Land Cover

This mid-Atlantic State has a diversified landscape. In the northwest, the Great Lakes Plain meets the Appalachian Plateau, which covers more than half the State. The Appalachian Mountains, another dominant land feature of the State, bisect the State diagonally from southwestern to northeastern Pennsylvania. Southeast of the Appalachian Mountains, the Piedmont Plateau meets the Great Atlantic Plain and is home to a substantial agriculture industry. Forests are located throughout the State with ash, hickory, aspen, oak, and pine being the most common tree species. Forests dominate the Allegheny Plateau in the northern and western parts of the State. Water makes up slightly less than three percent of the State’s area with Lake Erie accounting for the majority. Major rivers in Pennsylvania include the Delaware and the Susquehanna in the eastern region of the State with the Monongahela and Allegheny joining at Pittsburgh to form the Ohio River in the Midwest region of the State.
