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): 141X–Tug Hill Plateau
MLRA 141 is entirely in New York and makes up about 1,173 square kilometers (3,037 square kilometers). It consists of a relatively small but unique upland that lies just off the eastern end of Lake Ontario and west of the Black River Valley and Adirondack Mountain region. It is essentially a north- and east-facing glaciated cuesta scarp and is underlain by thick Wisconsin till and small areas of outwash. Most of the plateau is woodland, so forestry and recreation are the primary uses, but small isolated dairy operations and hobby farms are located around the perimeter.
The area is bordered on the east by the Black River Valley, on the north by the St. Lawrence Lowland, on the west by the Ontario Lowland, and on the south by the Upper Mohawk Valley. The northern and eastern boundaries of MLRA 141 are distinct where they contact the physiographically dissimilar southwestern part of MLRA 142 (St. Lawrence-Champlain Plain). The western and southern boundaries are also distinct where they contact the physiographically dissimilar MLRA 101 (Ontario-Erie Plain and Finger Lakes Region).
Ecological site concept
This site occurs mostly on well- to moderately well-drained loam soils and associated somewhat poorly-drained soils. Bedrock is greater than 20 inches below the mineral soil surface. Soils are semi-rich due to calcareous bedrock material from which they are derived. This site is commonly found on backslope and footslope positions but may occur on flats or any number of landforms. The vegetation is characterized by northern hardwoods, particularly sugar maple, yellow birch, and beech, with basswood, ash, and northern white cedar as less-abundant indicators of these semi-rich soils. Shallower and wetter inclusions in this site typically produce more of these indicator species. On gentler slopes, these soils are often farmed.
