Pennsylvania, whose name means "Penn's Woods," is known for the beauty of its forests. Beyond their beauty and recreational opportunities, the state's 17 million acres of forests help keep air and water clean, provide habitat for plants and wildlife, and furnish many wood products and other ecosystem services. Founded in 1895, Pennsylvania's Bureau of Forestry works to conserve and sustain these forests through careful management. Its staff includes men and women dedicated to conservation across forest management, including silviculture, forest fires, geology, forest health, education, wildlife and plant biology, and road and trail maintenance. They work with private forest owners and manage the state's public forest land, including more than 2.2 million acres of state forest managed sustainably for many values and uses. This state forest is one of the largest expanses of public forest land in the eastern United States. The mission is to ensure the long-term health, viability, and productivity of the Commonwealth's forests, conserve native wild plants including Pennsylvania's 3,000 native wild plant species, provide public outreach on woodlot management, wildfire prevention, invasive species control, and urban tree planting, sustainably harvest timber while enhancing forest health and creating diverse wildlife habitats, manage habitats that support healthy wildlife populations such as the ruffed grouse, and protect lives, property, and natural resources from wildfire damage.
