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.

Figure 1. Mapped extent

Areas shown in blue indicate the maximum mapped extent of this ecological site. Other ecological sites likely occur within the highlighted areas. It is also possible for this ecological site to occur outside of highlighted areas if detailed soil survey has not been completed or recently updated.

MLRA notes

Major Land Resource Area (MLRA): 120B–Kentucky and Indiana Sandstone and Shale Hills and Valleys, Northwestern Part

120B-Kentucky and Indiana Sandstone and Shale Hills and Valleys, Northwestern Part is located in Indiana and covers about 3,040 sq.mi. This area is in the Highland Rim Section of the Interior Low Plateaus Province of the Interior Plains. Tributaries of the Ohio River dissect the uplands. The major streams and rivers have well defined valleys with broad flood plains and numerous stream terraces. The geologic materials in this area are of Early and Middle Pennsylvanian and Late Mississippian age. The rocks consist mainly of flat-lying, interbedded sandstone, shale, coal, and siltstone with minor areas of limestone. Bedrock outcrops are common on river bluffs. The dominant soil orders in this MLRA are Alfisols, Ultisols, and Inceptisols. The soils in the area have a mesic soil temperature regime, a udic or aquic soil moisture regime, and dominantly mixed mineralogy. They formed dominantly in less than 40 inches of loess and in residuum or colluvium derived from sandstone, shale, and siltstone. The soils range from moderately deep to very deep and from poorly drained to somewhat excessively drained and are loamy, silty, or clayey. Fragiudalfs (Apalona, Zanesville) and Hapludalfs (Wellston) are the dominant soils on ridgetops and upper slopes. Hapludults (Adyeville) and Dystrudepts (Tipsaw) are on side slopes, and Hapludults (Tulip) are on footslopes. Hapludalfs (Deuchars, Ebal, Kitterman) are on structural benches and scarps. Endoaquepts (Zipp), Epiaqualfs (McGary), and Hapludalfs (Shircliff, Markland) are formed in lacustrine sediments. Hapludults (Millstone), Hapludalfs (Elkinsville), Fragiudalfs (Sciotoville), and Epiaqualfs (Hatfield) are on terraces along the Ohio River. Hapludolls (Huntington), Eutrudepts (McAdoo, Lindside), and Endoaquepts (Newark) are on flood plains along the major streams. Dystrudepts (Cuba, Steff), Eutrudepts (Gatchel, Haymond), Endoaquepts (Belknap, Stendal), and Fluvaquents (Birds, Bonnie) are on local flood plains.

Ecological site concept

The Deep Moderately Well Drained Sandstone-Shale Uplands are found in deep and moderately drained soils on structural benches and hills (backslopes and shoulders) . Representative soils include: Branchville, Deuchars, Ebal, Kitterman.

The communities described in this provisional document reflect plant communities that are likely to be found on these soils and have not been field verified. This PES describes hypotheses based on available data of many different scales and sources and has not been developed utilizing site-specific ecological field monitoring. This PES does not encompass the entire complexity or diversity of these sites. Field studies would be required to develop a comprehensive and science-based native plant restoration plan for these sites.

State 1, Phase 1.1.
Forestland. Plant species dominants:
white oak (Quercus alba) - American beech (Fagus grandifolia) / flowering dogwood - maple leaf viburnum (Viburnum acerifolium) /smooth Solomon's seal (Polygonatum biflorum) -sedges (Carex spp.)

State 2, Phase 2.1.
Pasture. Plant species dominants: Schedonorus arundinaceus (tall fescue).
Species present are dependent upon seeding and management.


State 3, Phase 3.1. Transitional Field State.
The transitional phase plant community composition will depend upon previous land uses – pasture type, management while in pasture (high quality pasture versus minimal managed grass-shrub –sapling community), and adjacent seed sources. State 3 listed below is assuming a transition from a fescue pasture. This phase is best described as an old field habitat with a mixture of native and introduced grasses and a variety of native and non-native herbs, forbs, seedlings, and saplings. Nearby available seed sources will greatly influence the makeup of this successional community.

Plant species dominants:
maple (Acer spp.) – ash (Fraxinus spp.) / berries (Rubus spp.) – sumac ( Rhus spp.) / giant ironweed (Vernonia gigantea) - fescue (Schedonorus arundinaceus)

State 4 Old Pioneer Cropland (lower slopes)
Phase 4.1: henbit deadnettle (Lamium amplexicaule) – mouse-eared chickweed (Cerastium L. )
Abandonment of cropland would result in many weed species taking over the site. Initially, annual weeds would be predominate followed by grasses, shrubs and pioneers trees.

State: 5. Cropland (lower slopes)
Phase 5.1: Plant species dominants: dependent upon seeding and management. Most common crops are corn and soybeans.
Restoration of states 2-5 to the reference community would require long-term, intensive management inputs.
