Hearts Content National Scenic Area is a tract of old-growth forest in Warren County, northwestern Pennsylvania. It represents one of the few remaining old-growth forests in the northeastern United States that contain white pine.[2] The area is protected as a National Scenic Area within the Allegheny National Forest.[3]
While many of the region's forests were being clear-cut, the Wheeler and Dusenbury Lumber Company held the 20acres tract of old-growth forest at Heart's Content from 1897 until 1922, when they deeded it to the United States Forest Service.[4] In 1934, the Chief of the Forest Service recognized the old-growth stand and 102acres of surrounding land as a National Scenic Area. The forest became a National Natural Landmark in 1973.[5]
H.J. Lutz's 1930 study of Hearts Content was one of the earliest quantitative analyses of plant communities in an old-growth forest,[2] and it remains influential in the field of ecology.[6] Lutz concluded that the even-aged white pine stand established following a major disturbance in the 17th century, such as a fire (possibly set by Native Americans during the Beaver Wars); since then, the species has not reproduced under the closed canopy. By relocating and resampling Lutz's original plots, Whitney documented 50 years of changes in the structure and composition of the stand.[6] During this time, dense deer populations have reduced the regeneration of many tree and herb species.[6] [7]
Hearts Content represents E. Lucy Braun's hemlock-white pine-northern hardwood forest type.[8] The old-growth forest is from 122acres to 150acres in extent, but the scenic area is most famous for its 20acres of tall white pine and Eastern hemlock.[9] Many of these trees have diameters of over 40inches and heights of over 140feet,[2] and most of the white pine are between 300 and 400 years old. American beech is also plentiful in the forest, but is affected by Beech bark scale.[3] Hay-scented fern covers much of the understory due to overbrowsing by deer.[3]
Visitors can walk an easily accessible, 11NaN1 loop trail through the old-growth forest.[4] A picnic area, campground and several other trailheads are nearby. A 6.41NaN1 cross-country ski trail passes through the area on old railroad grades.[4] There are also numerous camps owned by private individuals in the area.
