Rich Boulderfield Forest (Central Appalachian-Piedmont)

American basswood and American bladdernut are common in the Rich Boulderfield Forest, which occurs on slopes partially covered with boulders. (There is more than one type of Rich Boulderfield Forest; this one is found in the Central Appalachian mountains and in the Piedmont.)

This natural community is found on slopes in the Central Appalachian mountains, usually facing a river or stream. Boulders are a prominent feature of the surface, but typically cover less than half.

More About This Natural Community

The Rich Boulderfield Forest occurs on slopes partially covered with boulders. The boulders come from bedrock high in calcium-rich minerals that promote plant growth. As the boulders erode, they contribute to soil fertility. Nutrient-loving plants grow here, but they may be somewhat widely spaced because of all the boulders.

Trees in this community include American basswood, white ash, and sugar maple. In the shrub layer, American bladdernut is common. In the spring and summer look for the blooms of cutleaf toothwort, squirrel-corn, and pale jewelweed.
