The Allegheny Highlands forests are a temperate broadleaf and mixed forests ecoregion located in a large part of the Allegheny Plateau physiographic province, including both unglaciated and glaciated portions, in Pennsylvania and New York within North America, as defined by the World Wildlife Fund. The United States EPA defines the area as belonging to the Northern Central Appalachians and Northern Appalachian Plateau and Uplands ecoregions.

Cook Forest State Park is a 8,500-acre (3,440 ha) Pennsylvania state park in Farmington Township, Clarion County, Barnett Township, Forest County and Barnett Township, Jefferson County, Pennsylvania in the United States. Located just south of the Allegheny National Forest, the park is a heavily wooded area of rolling hills and mountains along the Clarion River in northwestern Pennsylvania. Cook Forest State Park is known for some of America's finest virgin white pine and hemlock timber stands and was once called the "Black Forest" due to the preponderance of evergreen tree coverage.
