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): 140X–Glaciated Allegheny Plateau and Catskill Mountains
This area is primarily in the Southern New York Section of the Appalachian Plateaus Province of the Appalachian Highlands. The top of the dissected plateau in this MLRA is broad and is nearly level to moderately sloping. The narrow valleys have steep walls and smooth floors. The Catskills in the east have steep slopes. Elevation is typically 650 to 1,000 feet on valley floors; 1,650 to 2,000 feet on the plateau surface; and 3,600 feet or more in parts of the Catskills.
The average annual precipitation in most of this area is 30 to 45 inches. Rainfall occurs as high-intensity, convective thunderstorms during the summer, but most of the precipitation in this area occurs as snow. The average annual temperature is 40 to 50 degrees F.
The dominant soil order in this MLRA is Inceptisols. The soils in the area dominantly have a mesic soil temperature regime, an aquic or udic soil moisture regime, and mixed mineralogy. Frigid soils are found within the higher elevations.
This area supports forest vegetation, particularly hardwood species. Beech-birch-maple and elm-ash-red maple are the potential forest types. The extent of oak species increases from east to west, particularly in areas of shallow and dry soils. In some areas conifers, such as white pine, are important. Aspen, hemlock, northern white-cedar, and black ash grow on the wetter soils. In some parts of the area, sugar maple has potential economic significance. Some of the major wildlife species in this area are white-tailed deer, cottontail, turkey, pheasant, and grouse.

Ecological site concept
Landform/Landscape Position:
The site occurs on bedrock controlled benches, steps, and footslopes. Slopes are mostly under 20% but can range up to 50%.
Soils:
The soils consists of very deep to moderately deep, moderately well to somewhat poorly drained soils formed in loamy till derived from sandstone, siltstone, and shale. Soil temperature regime is frigid. Reaction is very strongly acid or strongly acid throughout the mineral soil. Soil components include Ischua, Gretor, Salamanca, Middlebrook, Hornellsville, and Almond.
Vegetation:
Reference community is a red maple-red oak-beech dominant hardwood Forest along wetland margins. Characteristic vegetation includes:
Trees: Red maple (Acer rubrum), American beech (Fagus grandifolia), sugar maple (Acer saccharum), red oak (Quercus rubra), yellow birch (Betula alleghaniensis). Conifers such as eastern white pine (Pinus strobus) and hemlock (Tsuga canadensis) are minor components.
Shrubs: Spicebush (Lindera benzoin), highbush blueberry (Vaccinium corymbosum), American witch-hazel (Hamamelis virginiana), hobblebush (Viburnum lantanoides).
Herbaceous: Cinnamon fern (Osmundastrum cinnamomeum), Jack-in-the-pulpit (Arisaema triphyllum), and sessile-leaved bellwort (Uvularia sessilifolia)
