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 till plains, drumlinoid ridges, hills, benches Slopes are mostly less than 25 percent but can range up to 50 percent.
Soils:
The soils consists of very deep, somewhat poorly drained to moderately well drained soils that formed in glacial till derived mostly from sandstone, shale, and siltstone. Soils are shallow to moderately deep to a fragipan (root restricting layer). Representative soils are Caneseraga, Dalton, Erie, Langford, Mardin, Morris, Rushford, Scriba, Shohola, Swartswood, Wellsboro, and Wurtsboro.
Vegetation:
The reference community is considered to be an oak-hickory forest characterized by red oak, white oak, mockernut hickory, red maple, American beech, tuliptree, maple-leaved viburnum, shadbush, witch-hazel, spicebush false Solomon's-seal, and wood ferns.
