General information

Provisional. A provisional ecological site description has undergone quality control and quality assurance review. It contains a working state and transition model and enough information to identify the ecological site.

MLRA notes

Major Land Resource Area (MLRA): 129X–Sand Mountain

Major Land Resource Area (MLRA) 129 is in Alabama (96 percent), Georgia (3 percent), and Tennessee (1 percent). It makes up about 8,030 square miles (20,805 square kilometers). The towns of Jasper, Cullman, and Fort Payne, Alabama, are in this MLRA. Interstate 65 crosses this area from north to south, and Interstates 24 and 59 join in the area just west of Chattanooga, Tennessee, which is just outside the northeast tip of the MLRA. Areas of the Redstone Arsenal Military Reservation are in the northern part of the MLRA. The William B. Bankhead National Forest and the Sipsey National Forest Wilderness are in the western part.

Most of this area is in the Cumberland Plateau Section of the Appalachian Plateaus Province of the Appalachian Highlands. This MLRA is deeply dissected and consists mainly of a series of rather narrow valleys, steep escarpments, and broad plateaus that are underlain by consolidated bedrock. Elevation ranges from 245 to 2,200 feet (75 to 670 meters). Valley floors are commonly about 100 to 400 feet (30 to 120 meters) below the adjacent plateau summits, but local relief may be as much as 1,200 feet (365 meters). The extent of the major Hydrologic Unit Areas (identified by four-digit numbers) that make up this MLRA is as follows: Mobile-Tombigbee (0316), 50 percent; Middle Tennessee-Elk (0603), 25 percent; Alabama (0315), 21 percent; and Middle Tennessee-Hiwassee (0602), 4 percent. The Sipsey Fork, Locust Fork, and Mulberry Fork Rivers, headwaters of the Black Warrior River, are in this area. The Tennessee River forms part of the northern boundary of the area.

Classification relationships

231C-Southern Cumberland Plateau Section
The terrain is gently sloping tablelands of level-bedded sanstone formations and hilly to mountainous terrain consisting of shale and sandstone slopes forming deep canyons with steep connecting escarpment. Forests are largely oak-pine, loblolly-shortleaf pine, or oak-hickory cover types (McNab et al. 2005).

Ecological site concept

This Provisional Ecological Site (PES) occurs in uplands with underlying acidic sandstone, sometimes containing thin strata of shale or siltstone. This site is used for farming and important crops include soybeans and corn, although other crops are also grown. Pasture and hay are common on this site. The areas on this site that occur as forests are primarily second growth. Important species include white oak, post oak, black oak, chestnut oak, tulip poplar, blackgum and hickory. Some pines occur on areas that have remained continuously in forest, but loblolly and shortleaf pines are the principal cover in abandoned cropland and pasture. Pine plantations do occur. In the past they have been planted to loblolly pine but the shift now is to encourage planting shortleaf pine. Virginia pine also occurs across this site.

It is unclear what the reference condition is for this site.

This site is of large extent.

Ecological dynamics

This PES is utilized for agriculture. Cropland is important. Soybeans and corn are among the most frequently grown crops. Pasture is also a land-use on this site. Most forests are second-growth and are predominated by the upland oak species. However, where cropland or pastureland has been abandoned, shortleaf and loblolly pine often colonize.

It is impossible to determine reference conditions for this provisional ecological site and very little data exist on vegetation communities. However, it is likely that the most fitting NatureServe description is "Allegheny-Cumberland Dry Oak Forest and Woodland - Hardwood" (CES202.359). This system encompasses dry hardwood forests on predominately acidic substrates. These forests are typically dominated by Quercus alba, Quercus falcata, Quercus prinus, Quercus coccinea, with lesser amounts of Acer rubrum, Carya glabra, and Carya alba. (NatureServe, 2017).*

Further field investigation is needed to determine the true nature of ecological communities and dynamics associated with this site. Likely, pine species are more important on this site than the NatureServe description indicates because of the farther south location of this site.

Upland Forest State

Figure 8. Typical forested state in spring.

Figure 9. Sandstone outcrop

Mixed hardwoods and some pines (loblolly, shortleaf and Virginia) occur on this site where it has not been cleared for pasture or crops. When cleared and abandoned, typically pines will colonize. Many of these stands have been logged or disturbed in the past. There is no way to determine true reference conditions so this should be considered a naturalized state.

State 2
Pasture State

Managed pasture for a variety of livestock is a typical land-use on this site.

State 3
Invaded State

Invasive non-native plants are problematic on this site and can colonize to the point of preventing natural regeneration from occurring. Any management recommendation for naturalized stands should consider exotic pest plants as a hazard. Privet was the most commonly noted species.

State 4
Cropland

A variety of crops are grown on this site. For the purposes of this model, no detail will be provided because they are diverse and would have very different management approaches. Crops grown on this site include cotton, corn, oats, sorghum, cowpeas, soybeans, sweet potatoes, Irish potatoes, hay, orchards, and vegetables.

Rangeland health reference sheet

Interpreting Indicators of Rangeland Health is a qualitative assessment protocol used to determine ecosystem condition based on benchmark characteristics described in the Reference Sheet. A suite of 17 (or more) indicators are typically considered in an assessment. The ecological site(s) representative of an assessment location must be known prior to applying the protocol and must be verified based on soils and climate. Current plant community cannot be used to identify the ecological site.
