Unusual Plants
* Showy orchis was present in Hemlock-Mixed Mesophytic and low-elevation Rich Cove forest near Saddle Ridge. These communities are associated with the Left Prong of Mill Creek. Hearts abustin' was found near a tributary in the same area.
* A patch of wild bleeding heart (Dicentra eximia) was found on a steep, moist valley slope in the Saddle Ridge area.
* High Elevation Northern Red Oak forest (located at the top of a tributary of the Right Prong of Mill Creek) had pockets of noticeably richer herb diversity than surrounding forests. Native sedge, bluets, Indian pipe, a kind of cress, mosses, and galax were found amid moist rock outcrops.
* Pockets of rich herb diversity were found in Rich Cove and Submesic Oak forests in upper Prichard Creek. Small eastern hophornbeam trees were found in upper Prichard Creek and upper Newberry Creek.
* Rocky seeps along upper Newberry Creek harbor uncommon or rare herbs.
* Upper Newberry Creek has high herb diversity in Rich Cove forests near the Blue Ridge. Deep dark humus (also known as Porters Loam) provides some of the basis for this high diversity.
* Mesic Oak forest in the upper section of the west fork of Newberry Creek had numerous herbs that are often associated with Rich Cove forests (such as blue cohosh and toothwort). This area resembles a similar forest type in Middle Creek RNA. |
