Briertown Mountain
Approximate size: 1,917 acres
Old growth acreage: 986
In addition to the 986 acres if old growth, this unit contains one candidate old growth site. Briertown Mountain is also included in the North Carolina Natural Heritage Listing. The Forest Communities include: Rich Cove (low elevation), Basic Mesic Forest, Mesic Oak, Dry Oak, and Dry Oak-Pine. Mixed Riverine forest is present along the Nantahala River, with varying degrees of human and beaver disturbance. Numerous sizable American sycamore and American beech trees stand along the river.
The largest slippery elm tree the Western North Carolina Alliance found in its old growth survey-40 inches in diameter-stands next to the river in this unit. Rich Cove and Acidic Cove forests are also present in riverine environments. A vein of marble crosses underneath the Nantahala River, and black walnut trees were found on the banks of the river near this vein.
Blowing Springs is a Special Interest Area. The substrate in this immediate area is marble, and numerous rare herb species are present. The Swain County listing of the rare synandra (Synandra hispidula) may be in the Blowing Springs area. Ted Snyder has found live American chestnut trees on the main ridge of Briertown Mountain, some bearing seed. Upland sections of this mountain have a meta-siltstone substrate. This forms a planed rock that breaks off in pieces and is difficult to traverse. Soils in this upland area are quick draining, and forest communities are much dryer. |
