Energy
The development of energy resources such as wood, coal, oil and natural gas has influenced much of Pennsylvania’s landscape. Repeated timbering of the forests for fuel, tanbark and lumber over the past 300 years has restricted old growth forests to small patches, often on steep, nearly inaccessible, slopes. While many of Pennsylvania’s forests are recovering with better management in the past 100 years, extraction of other resources like oil, gas, and coal also impact the landscape. Past coal mining practices have left a legacy of scarred landscapes and polluted waterways in many of the coal regions of the state. Current natural gas development of the Marcellus and Utica Shale presents another challenge for Pennsylvania as development will require new infrastructure across much the rural areas of western and northern Pennsylvania, risking further fragmentation and disturbance on a recovering landscape. In order to minimize impacts to Pennsylvania’s living natural resources, the future development of energy resources will require planning and care to avoid the mistakes of the past.

Natural Gas
The Appalachian Basin region contains one of the largest natural gas reserves in the world. The Marcellus Shale and Utica Shale formations underlie an estimated two-thirds of Pennsylvania, and the recent development of deep natural gas reserves in shale formations is changing the landscape of the region.
