MLRA notes

Major Land Resource Area (MLRA): 127X–Eastern Allegheny Plateau and Mountains

This ecosite is found in mountains, plateau in MLRA 127: Eastern Allegheny Plateau and Mountains. This site occupies the Allegheny Mountain Section of the Appalachian Highlands of the Appalachian Plateau Province. The deeply dissected plateau in this area terminates in a high escarpment, the Allegheny Front, in the eastern part of the area. Steep slopes are dominant, but level to gently rolling plateau remnants are conspicuous in the northern part of the area. The area is dominantly forest, containing large blocks of state forest, game lands, and national forest. Less than one-tenth of the MLRA consists of urban areas.

Ecological site concept

From Landfire http://www.landfire.gov/index.php:

This ecological section comprises part of the Appalachian Plateaus geomorphic province (USDA Forest Service 1995). It is a maturely dissected plateau characterized by high hills, sharp ridges, and narrow valleys. Bedrock is overlain by Quaternary residuum on the ridges and hilltops, colluvium on the slopes, and either or both alluvium and Pleistocene lacustrine materials in the valleys. Udalfs, Udults, and Ochrepts dominate, in combination with mesic soil temperature regime, an udic soil moisture regime, and mixed or illitic mineralogy. Soils formed in parent materials are divided into five groups: residual material, which developed in place by the weathering of underlying bedrock; colluvial material which weathered from bedrock strata transported by water and gravity to the lower slopes; alluvium, lacustrine sediments and outwash deposited by water; and loess deposited by wind. Precipitation averages 35 to 45in (900 to 1,150mm0150mm); it occurs mainly during summer, winter, and spring. Rain on snow is common during winter and early spring. Summers are dry with low humidity. Temperature averages 52 degrees F (11 degrees C). The growing season is 120 to 180 days. This ecological section is characterized by a relatively high density of streams, with gradients ranging from high, steep headwaters streams to low gradient rivers that flow into the OH River.

These sites generally occur on uplands with divergent convex slopes.

Ecological dynamics

Information contained in this section was adapted from several sources. The information presented is representative of very complex vegetation communities. Key indicator plants, animals 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 aspect. The reference plant community is not necessarily the management goal. The species lists are 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.

NatureServe (2007) provides the following description pertaining to this ecological system CES202.592 -- Northeastern Interior Dry-Mesic Oak Forest . These oak-dominated forests are one of the matrix forest systems in the northeastern and north-central US. Occurring in dry-mesic settings, they are typically closed-canopy forests, though there may be areas of patchy-canopy woodlands. They cover large expanses at low to mid elevations, where the topography is flat to gently rolling, occasionally steep. Soils are acidic and relatively infertile but not strongly xeric.

Vegetation Description
The vegetation consisted of forests dominated by oaks of dry-mesic conditions, especially white oak (Quercus alba) and red oak (Quercus rubra), and, on drier sites, chestnut oak (Quercus prinus), black oak (Quercus velutina), and scarlet oak (Quercus coccinea). Scarlet oak is absent at the northern edge of the system range. Along with oaks are varying amounts of hickory (Carya spp.), red maple (Acer rubrum), and other species such as white pine (Pinus strobus) and white ash (Fraxinus americana). American chestnut (Castanea dentata) was a prominent tree in these forests before chestnut blight eradicated it as a canopy constituent (NatureServe 2007). Common shrubs include mountain laurel (Kalmia spp.), greenbriar (Smilax spp.), blueberries (Vaccinium spp.), and huckleberries (Gaylussacia spp.). In the Ridge and Valley region, bear oak is an important shrub component. Herbs, forbs, and ferns are usually sparse to moderate in density. Areas experiencing frequent fire had a greater abundance of grasses and sedges.

Most oaks are long-lived with typical age of mortality ranging from 200 to 400yrs. Scarlet and black oaks are shorter-lived with typical ages being approximately 50 to 100yrs, while white oaks can live as long as 600yrs. Extreme wind or ice storms occasionally create larger canopy openings. The dry-mesic oak forest is predominantly Fire Regime I, characterized by low-severity surface fires. Historically, indigenous fires accounted for over 95% of the ignitions over these landscapes. Vegetation types varied based on fire frequency and intensity. Grassland prairies burned often (annually, biennially) and were probably associated with flat-to-slightly rolling terrain that effectively carried fire. These grasslands, deliberately maintained by Native Americans for hunting purposes, were probably scattered throughout the forest matrix. Oak-hickory tree-sprout and shrub thickets occurred where fire frequency was a bit less, probably 3-9yrs. Also, sprout conditions would arise immediately after catastrophic burns that would top-kill tree-dominated communities. Savannas and woodlands developed within a moderate burning regime, with fire return intervals averaging every 5 to 15yrs. Closed-canopy oak-hickory forests would develop where fire return intervals stretched beyond 15yrs. Shade-tolerant, fire-sensitive maples (and associated late-successional trees) would regenerate and form understories beneath oak-hickory canopies when fire was excluded over several decades. With continued fire exclusion, maple and other late successional species would gradually replace overstory oaks and hickories through gap capture (Sutherland and Hutchinson 2003). A mosaic of vegetation types comprised oak-hickory landscapes contingent on fire history (Cutter and Guyette 1994). In a recent study on fire history of a red oak stand in West VA it was found that fire intervals ranged from 7 to 32yrs from 1846 to 2002 with a median of approximately 16yrs, and prior to the fire control era ranged from 7 to 15yrs (Schuler and McClain, 2003). Schuler and McClain stated that these observations did not deviate significantly from previous research in the oak forests of OH, MD, and Missouri. -- the above description was taken from RA model R6OAHI -- Oak Hickory.

Community 1.1
Quercus montana - Quercus rubra / Hamamelis virginiana Forest

Central Appalachian Dry-Mesic Chestnut Oak - Northern Red Oak Forest (CEGL007057) occurs on upper slopes. The canopy is codominated by Quercus montana and Quercus rubra. Associated canopy species include Liriodendron tulipifera, Acer rubrum, Carya glabra, Carya ovalis, Carya tomentosa, Acer saccharum, Tilia americana, Fagus grandifolia, and Betula lenta. The tall-shrub layer is most often characterized by Hamamelis virginiana and Acer pensylvanicum. The lower shrub layer is patchy and contains a mixture of scrambling vines, ericads, and non-ericaceous species. The herbaceous layer is usually sparse but may include Dryopteris marginalis, Dioscorea quaternata, Eurybia divaricata, Ageratina altissima, Polygonatum biflorum, Solidago caesia, Festuca subverticillata, Thelypteris noveboracensis, Sanicula trifoliata, Prenanthes altissima, Polystichum acrostichoides, Desmodium nudiflorum, Galium latifolium, Houstonia purpurea, and Maianthemum racemosum. This association is more or less intermediate in site conditions and composition between oak / heath forests of exposed, xeric, infertile sites and richer cove or montane oak-hickory forests of sheltered, fertile sites.

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.
