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): 111X–Indiana and Ohio Till Plain
111E – Indiana and Ohio Till Plain, Eastern Part. Most of this area is in the Till Plains Section of the Central Lowlands Province of the Interior Plains. The northeast tip of the area is in the Southern New York Section of the Appalachian Highlands. The entire area has been glaciated. It is dominated by ground moraines that are broken in places by kames, lake plains, outwash plains, terraces, and stream valleys. Narrow, shallow valleys commonly are along the few large streams in the area. Elevation ranges from 580 to 1,400 feet (175 to 425 meters), increasing gradually from west to east. Relief is mainly a few meters, but in some areas hills rise as much as 100 feet (30 meters) above the adjoining plain.
The extent of the major Hydrologic Unit Areas (identified by four-digit numbers) that make up this MLRA is as follows: Scioto (0506), 33 percent; Muskingum (0504), 31 percent; and Western Lake Erie (0410), 28 percent; Upper Ohio (0503), 5 percent; and Southern Lake Erie (0411), 3 percent. The headwaters of many rivers in central Ohio, including the Vermillion, Black Fork, Sandusky, Little Scioto, and Olentangy Rivers, are in this MLRA.
This MLRA is underlain by late Devonian shale and sandstone. Surficial materials include glacial deposits of till, glaciolacustrine sediments, and outwash from Wisconsin and older glacial periods.

Ecological site concept
This woodland site was, historically, a mixed hardwood site with sugar maple and red oak being the dominant canopy species. Canopy associates include American beech, basswood, black cherry, and white oak. Fires were low frequency, high intensity events on the site at maturity and occurred very rarely, and even then only after large windthrow events or extreme drought. Low intensity, surface fires were more common in the mid seral stages when more fire tolerant species, oaks specifically, were more dominant in the canopy. Small gap disturbances are the most common overall disturbance mechanism and often result from windthrow or disease. Selective tree harvest moves the site to a new state where the canopy becomes dominated by less desirable timber species like beech, basswood, hickory and elm species. Currently, large areas of the site have been converted for agricultural use, mostly row crops and small grains, but some are being used for hay and pasture as well.
