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.

NatureServe (2007) provides the following description pertaining to this system type. 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.

Climatic features

The regional climate of the unglaciated Central 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. High-intensity, convective thunderstorms are common in summer. 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.

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.

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.

State 1
Agricultural Land

Land managed for agricultural production of crops and livestock.

Community 1.1
Pasture (Grasses, Forbes) or Cropland (Grasses, Forbes)

This community phase may contain a wide variety of plants depending on the level of management. In pasture circumstances that are managed tall fescue, bluegrass and white clover will dominate the vegetation canopy. Without management such as prescribed grazing, nutrient management and weed control, less desirable forage species and weeds will invade.

State 2
Post Settlemet Forest

This forest vegetation community is the result of removing fire from the landscape, and poor logging techniques (high grading). Following European settlement fire as a management tool was abandoned and mesophication of the vegetation took place.

Community 2.1
Tree/Shrub/Herb

Maple (Red and Sugar)/Striped Maple Forest best captures the nature of this vegetation state. The dominate overstory canopy consist of Maples with minor canopy coverage of Tulip tree. The shrub layer contains Stripped maple, greenbrier and blackberry. The herb layer will contain flowering forbes (asters and goldenrod), ferns (woodferns) and grasses (native fescue, povertygrass).

State 3
Reference Pre-Contact Forest

The reference state can be represented by several communities within the Allegheny-Cumberland Dry Oak Forest and Woodland(Natureserve, 2007). Forest overstory canopies are oak dominated and generally closed canopy.

Community 3.1
Tree/Shrub/Herb

Chestnut Oak-White Oak/Mountain Laurel Forest best captures the nature of this vegetation state. The dominate overstory canopy consist of Oaks with minor canopy coverage of Hickory. The shrub layer contains mountain laurel, greenbrier and ericads. The herb layer will contain flowering forbes (asters and goldenrod), ferns (woodferns) and grasses (native fescue, povertygrass).

Transition T2A
State 1 to 3

The site agricultural management is abandoned and forest regrowth occurs through natural succession or tree planting.

Restoration pathway R3A
State 2 to 1

Remove undesirable species using herbicides, cutting or prescribed fire. Plant desired species if absent from the site.

Transition T3A
State 2 to 2

The site is logged and managed for agricultural land.

Transition T1A
State 3 to 2

The site is logged and managed for agricultural land.

Transition T1B
State 3 to 3

The site is logged and fire is suppressed allowing mesophication to occur.

Site Development and Testing Plan
Future work is needed, as described in a future project plan, to validate the information presented in this provisional ecological site description. Future work includes field sampling, data collection and analysis by qualified vegetation ecologists and soil scientists. As warranted, annual reviews of the project plan can be conducted by the Ecological Site Technical Team. A final field review, peer review, quality control, and quality assurance reviews of the ESD are necessary to approve a final document.

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.
