The site is steeply sloped, underlain by rock, with rocky outcrops. Slope: 15 to 65 percent. Aspect: Variable. The underlying geology of this area is Quartzite/Mica Schist, primarily of Precambrian-Paleozoic origin. (Source: USGS North Carolina Geologic Map Data.) The primary soil type in the collection area is classified as Ashe Series that is stony and very steep. The Ashe series consists of moderately deep, somewhat excessively drained soils on gently sloping to very steep ridges and side slopes of the Blue Ridge. They formed in residuum that is affected by soil creep in the upper part, and weathered from felsic or mafic igneous and high-grade metamorphic rocks such as granite, hornblende gneiss, granodiorite, biotite gneiss, and high-grade metagraywacke. Slope ranges from 2 to 95 percent. The surface layer to 5cm deep is comprised of moderately decomposed organic matter and leaves, twigs, and roots. Layers to 70cm deep range from very dark grayish brown to brown sandy loam with weak medium and coarse granular structure that is friable. A few fine flakes of mica can be found and these soils are very strongly acid. (Source: NRCS Web Soil Survey.)Wild material2166141WLP 3432

This location was accessed from the east where Miller Avenue meets the fire road, approximately 2 kilometers away. There is no vehicular access to the collecting area. Becoming locally uncommon. This local population is likely to be extirpated in the next 20-30 years. This collector has hiked through this area for more than 35 years and seen dramatic changes in the population. When first observed, Kalmia latifolia was a dominant understory shrub on south- to west-facing slopes beneath a mature forest canopy. Over the years, at least one forest fire has significantly reduced the population, along with a continuing increase in deer populations, resulting in catastrophic browse damage. The absence of a mature forest canopy and periods of drought have almost certainly also resulted in decline of this population. While collecting seed from scattered mature plants well above deer browse levels, this collector also noted that there was virtually no recruitment taking place.39.32811200, -77.72242400287Plants are growing in part-shade to shade of a deciduous upland, very rocky, and dry forest community.

It is one of the most dominant understory plants in woodlands. This species is a common understory shrub throughout the entire region in upland dry woodland habitats.40.63862000, -75.99071200430Plants are growing primarily in shade to part-shade on a dry-mesic to very dry, well-drained upland/montane habitat characterized by upland mixed deciduous and evergreen forest that is very rocky. All of the plants found in this habitat go through periods of drought during the growing season due to the limited litter/soil layer in which moisture can be held. The underlying geology of this area is of Silurian origin and comprised of Shawangunk Formation. This formation is primarily light- to dark-gray, fine- to very coarse-grained sandstone and conglomerate containing thin shale interbeds.
