MLRA notes

Major Land Resource Area (MLRA): 124X–Western Allegheny Plateau

Major Land Resource Area (MLRA): 124—Western Allegheny Plateau (USDA-NRCS, 2006)
MLRA 124, Western Allegheny Plateau extends from and includes western PA just north of Pittsburgh through southeastern OH to and includes northeastern KY. This area is primarily in the Kanawha Section of the Appalachian Province of the Appalachian Highlands. This MLRA is on an unglaciated dissected plateau with narrow level valley floors, rolling ridgetops, and hilly to steep slopes with dendritic stream drainages. A notable exception is the broad, Teays Valley, and other glacio-fluvial and glacio-lacustrine features attributed to nearby Pleistocene glaciation. Elevation ranges from 660 to 1310 feet (200 to 400 meters). The geology is predominantly cyclic beds of sandstone, siltstone, clay, shale and coal of Pennsylvanian age. Soils are dominated by Udalfs, Udults, and Ochcrepts with a mesic temperature regime in combination with five parent materials, residuum, colluvium, alluvium, eolian, and extra-glacial material of glacio-fluvial and glaciolacustrine mesic materials. The climate is predominately a humid continental to temperate, with 940 to 1145 millimeters (37 to 45 inches) of precipitation. Average annual temperature is 8 to 13 degree C (46 to 56 degrees F) with a freeze-free period averaging 185 days. Much of the areas is either forest or in farms, principally for hay and pasture, with fruits and vegetables grown locally. Coal and gas extraction are important industries in the northern part of the MLRA.

Ecological site concept

Within the dissected plateau of the unglaciated Western Allegheny Plateau, the Coarse Terrace and Plain ecological site is set in upland landscapes such as valleys, stream valleys, and plateaus consisting of a range of parent materials including old alluvium, glaciofluvial materials, glaciolacustrine, and sandy loess. The soils texture family is sandy and coarse-loamy. These soils are well-drained to excessively drained. Representative soils include: Allegheny Variant, Barbourville, Bogart variant, Boyer, Chavies, Chenago, Conotton, Lakin, Oshtemo, Plainfield, Rodman, Sparta, Watertown. Representative plant communities include: the Allegheny Plateau-Northeast Oak Forest, and the White Oak - Red Oak Dry-Mesic Acidic Forest.

Physiographic features

The Coarse Terrace and Plain ecological site consists of several parent materials including old alluvium, glaciofluvial materials, glaciolacustrine materials, and sandy loess. This ecological site can be found along old stream terraces, terraces, and alluvial fans in a variety of landscape settings including valleys, river valleys, and plateaus. Terraces and plains of the unglaciated, Western Alleghany Plateau are variable, with some sites derived from old alluvium derived from sandstone and siltstone, and other sites derived from eolian sands, and still other sites from glacial outwash. Even though this region of the Alleghany Plateau was not glaciated, meltwater rivers and stream deposited outwash sands along their course, and coarse windblown sediments were deposited near glacial fed rivers.

Climatic features

The regional climate of the unglaciated Western Allegheny Plateau is predominately a humid continental climate grading at the extreme southwestern corner a to humid temperate climate with hot summers and cool winters (Beck et al., 2018; Bailey, 2014). However, the local climate is highly influenced by the dissected terrain, where climatic variations may be greater at the local scale, e.g., cooler temperatures and shorter growing season at higher elevations and more northerly latitudes. Winter precipitation is mostly snow.

Climate change is occurring, and the resiliency of any ecological site will depend upon the direct and indirect effects upon component species and shifting atmospheric and soil conditions.

On these ecological sites, dry upland forests are at a low vulnerability risk to climate change with some impacts considered positive. Large gap disturbances from greater storm events, drier summer and fall conditions, and a potential increase in fire frequency, can favor oaks and hickories and more southern plant species. Greater frequency and magnitude of storm events may increase large gap disturbances coupled with drier conditions in summer and fall may increase wildfires (Butler et al., 2015).

Ecological dynamics

[Caveat: The vegetation information contained in this section is only provisional, based on concepts, not yet validated with field work.*]

The vegetation groupings described in this section are based on the terrestrial ecological system classification and vegetation associations developed by NatureServe (Comer et al., 2003). Terrestrial ecological SYSTEMS are specifically defined as a group of plant community types called ASSOCIATIONS that tend to co-occur within landscapes with similar ecological processes, substrates, and/or environmental gradients. They are intended to provide a classification unit that is readily mappable, often from terrain and remote imagery, and readily identifiable by conservation and resource managers in the field. A given system will typically manifest itself in a landscape at intermediate geographic scales of tens-to-thousands of hectares and will persist for 50 or more years. A vegetation association is a plant community that is much more specific to a given soil, geology, landform, climate, hydrology, and disturbance history. It is the basic unit for vegetation classification and recognized by the US National Vegetation Classification (FDGC, 2008; USNVC, 2017). Each association will be named by the diagnostic and often dominant species that occupy the different height strata (represented by tree, shrub, and herb layers). Within the NatureServe Explorer database, ecological systems are numbered by a community Ecological System Code (CES) and individual vegetation associations are assigned an identification number called a Community Element Global Code (CEGL).

Additional and more localized vegetation information can be provided by the various State Heritage Programs. Additional insights to the vegetation were provided by Plant Communities of Ohio: A Preliminary Classification (Anderson, 1982) and Terrestrial and Palustrine Plant Communities of Pennsylvania, 2nd Edition (Zimmerman et al., 2012).

Due to a long history of human activity, the reference condition more accurately reflects the current naturalized, minimally-managed state rather than the historic, pre-European settlement condition. Terraces and plains of the unglaciated, Western Alleghany Plateau are variable, with some sites derived from old alluvium derived from sandstone and siltstone, and other sites derived from eolian sands, and still other sites from glacial outwash.

The vegetation of the Coarse Terrace and Plain ecological site is quite varied but typically dominated by oak-hickory, and pine-oak. Within the reference state, the plant associations are predominately part of the Central Appalachian Dry Oak-Pine Forest system (CES202.591) and the Allegheny-Cumberland Dry Oak Forest and Woodland system (CES202.359) (NatureServe, 2020). Besides the mature plant community-types listed, other spontaneous, successional plant community-types may exist following natural disturbances.

Agents-of-change within any ecological site include both natural and anthropogenic stressors. Canopy disturbances such as fire, wind, and ice storms, will tend to favor oaks and pines. (Lafon et al., 2017). Conversely, fire suppression, a changing climate, and natural forest succession effect mesophication, a trend toward more shade tolerant species, e.g., white ash, sugar maple, red maple, American beech. (Nowacki et al., 2008). However, site conditions do influence the degree of mesophication. Mesophication is more subdued on more xeric ecological sites such as the Coarse Terrace and Plain ecological site. Where deer densities are high, deer browse has a pronounced effect on plant regeneration, structure, and species diversity. However, deer browse can vary across the landscape (Royo et al., 2017). Currently, deer browsing pressure in southeastern Ohio is relatively low (Apsley and McCarthy, 2004). Invasive and incursive plants can directly affect forest ecosystems in many ways; through direct competition for resources, alter fire or hydrologic conditions and affect species diversity. Insect pests and diseases such as the Gypsy moth, oak decline and armillaria root rot can cause reduced productivity and mortality in target oak species (Butler et al., 2015). Within the unglaciated Western Alleghany Plateau, most of the hills remain forested, with some agriculture on lands flat enough to support it. Agriculture and residential development are concentrated in the valleys. Surface mining for coal affects land and water to varying degrees (Ohio Div. of Wildlife, 2015; USDA-NRCS, 2006).

Other ecological states, a Semi-natural State and a Cultural State are recognized. The Semi-natural State would expect plant communities where ecological processes primarily operate with some conditioning by land management, e.g., managed forests, or plant communities that are an artifact of land management e.g., predominately invasive plants. The Cultural State is a completely converted or transformed state; heavily or completely conditioned by land management, e.g., cultivated lands, pasture/haylands, vineyards, and plantations, etc. Generally, the form of vegetation in the Semi-natural State or the Cultural State is not able to be specified until field work is conducted.

[*Caveat] The vegetation information presented is representative of complex plant communities. Key indicator plants and ecological processes are described to help inform land management decisions. Plant communities will differ across the MLRA because of the naturally occurring variability in weather, soils, and geography. The reference plant community is not necessarily the management goal. The drafts of species lists are merely representative and are not botanical descriptions of all species occurring, or potentially occurring, on this site. They are not intended to cover every situation or the full range of conditions, species, and responses for the site.

State 1
Reference State (minimally-managed)

As a result of a long history of human activity, the associations listed below, may in reality, reflect the current naturalized, minimally-managed state rather than the historic, pre-European settlement condition. Notice transition pathways are not always designated between some of the communities in the reference state because the differences in vegetation are more controlled by landscape position, rather than disturbances or management, or that the relationships are not understood. In addition, undisclosed successional plant community-types following disturbance may be included as community phases. Within the reference state, the plant communities are quite variable and may include: • Quercus (velutina, alba) / Vaccinium pallidum / Pteridium aquilinum Allegheny Plateau-Northeast Forest (CEGL006018) (Translated Name: (Black Oak, White Oak) / Blue Ridge Blueberry / Western Brackenfern Allegheny Plateau-Northeast Forest) [Common Name: Allegheny Plateau-Northeast Oak Forest]; or • Quercus velutina - Quercus alba - Carya (glabra, ovata) Forest (CEGL002076) (Translated Name: Black Oak - White Oak - (Pignut Hickory, Shagbark Hickory) Forest) [Common Name: Black Oak - White Oak - Hickory Forest] A less common plant community may include: • Pinus virginiana - Pinus (rigida, echinata) - (Quercus montana) / Vaccinium pallidum Forest (CEGL007119) (Translated Name: Virginia Pine - (Pitch Pine, Shortleaf Pine) - (Chestnut Oak) / Blue Ridge Blueberry Forest) [Common Name: Appalachian Low-Elevation Mixed Pine / Blue Ridge Blueberry Forest] (Source: NatureServe 2020)

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.

List species which BOTH characterize degraded states and have the potential to become a dominant or co-dominant species on the ecological site if their future establishment and growth is not actively controlled by management interventions. Species that become dominant for only one to several years (e.g., short-term response to drought or wildfire) are not invasive plants. Note that unlike other indicators, we are describing what is NOT expected in the reference state for the ecological site:
Perennial plant reproductive capability:
