The woodlands are primarily deciduous with a few evergreens infrequently mixed. Slope: 15 to 30 percent. Aspect: Northeast. Soil: The primary soil type in the area of this collection is classified as Rockland Series sandstone (Rc). The Rockland series consists of well drained soils formed in loamy colluvium from rotational landslides on slopes of stream valleys and dissections of ground moraines. Saturated hydraulic conductivity is moderate in the upper part of the profile and moderately slow in the lower part. Slopes range from 18 to 70 percent. Some pedons have buried leaves, twigs, and moss. Mass soil movement has left random remnants of soil structure from prior upslope soil development and has buried tree branches, leaves and moss. The upper 0-2 cm of soil contains slightly decomposed organic matter while lower soils layers to a depth of 58 cm are comprised of dark reddish-brown to brown silt loam and are moderately acidic. Below 58 cm the soils are generally dark reddish-brown silt loam and strongly to moderately alkaline. (Source:California Soil Resource Lab/NRCS Official Soil Series Descriptions). Geology: The underlying geology of this area is of Pennsylvanian origin and characterized as Pottsville Formation. It is characterized by light-gray thin to thick-bedded quartzose sandstone and conglomerate containing interbedded dark-gray shale, siltstone, and coal. Mapped on Lookout Mountain, Blount and Chandler Mountains, and Sand Mountain northeast of Blount County, and on the mountains of Jackson, Marshall, and Madison Counties north and west of the TN river.

Slopes range from 2 to 60 percent and soil is typically strongly acidic. Louisa Series soils The Louisa Series soils consist of shallow, somewhat excessively drained soils which formed over mica gneiss and schist bedrock. They occur on Piedmont uplands. Slopes are 6 to 80 percent. This soil is moderately acid. (Source: California Soil Resource Lab/NRCS Official Soil Series Descriptions).

Soils: The underlying geology of this area is of Eocene origin and characterized as Ocala Limestone. The Ocala Limestone consists of almost pure limestones with occasional dolomites. It can be subdivided into both lower and upper facies with the lower facies composed of a whitish to cream-colored, fine to medium grained, poorly to moderately hard, fossil rich grainstone and packstone. The upper Ocala is white and somewhat weak and poorly sorted. It is extremely fossil rich grainstone, packstone and wackestone and some chert is common in the upper facies.
