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 site is an upland site formed on glacial till parent materials located in a swell (convex) landscape position. It is located on summits, shoulders and backslopes on steep slopes that can be up to 50%. The soils are moderately well to well drained with the surface being in the loamy texture group.

The characteristic vegetation of the site is of a till forest with the understory and canopy dominated by sugar maple, American beech, and basswood. Canopy level associates include white oak, bitternut and shagbark hickory, and black walnut. The site is dominated by shade tolerant, fire sensitive species. The most common disturbance dynamic is individual tree or small group mortality or windthrow with catastrophic windthrow or damage from ice storms to occur very infrequently. The largest risk to extant natural representation of the site is by invasion of non-native plants that, if unchecked, can dominate the understory. This greatly changes the species richness and diversity of the understory as the non-native plants, particularly species of Asian bush honeysuckle, exclude most all other species. The dominant canopy level trees are not threatened by these species, however given enough time this change could alter the composition of the canopy by altering the species that can get established in the understory. Currently, the majority of this site is being used for corn and soybean rotations.

Climatic features

The average annual precipitation in this area is 35 to 41 (890 to 1,040 millimeters). Most of the rainfall occurs as convective thunderstorms during the growing season. About half or more of the precipitation occurs during the freeze-free period. Snowfall is common in winter. The average annual temperature is 48 to 52 degrees F (9 to 11 degrees C). The freeze-free period averages about 185 days and ranges from 165 to 205 days.

Ecological dynamics

The historic plant community of the Till Ridge ecological site is a till forest with the dominant species in the canopy being sugar maple, beech, and basswood. Canopy associates include white oak, bitternut and shagbark hickory, and black walnut. This site is dominated by fire sensitive and shade tolerant species. Species with these characteristics make it to the canopy via gap-phase recruitment on a local scale. Large scale, stand replacing disturbance was very infrequent, but was usually the result of large scale windthrow or ice damage.

State 1
Till Ridge Forest

This is the diagnostic plant community for this site. In reference condition, this site was dominated by sugar maple, beech and basswood trees. An earlier successional phase of this site is comprised largely of shrubs and pioneering species like white oak and white ash. Stand replacing events were very uncommon. Small gap disturbance was the most common disturbance event that allowed propagation of these species.

Dominant plant species

sugar maple (Acer saccharum), tree
American beech (Fagus grandifolia), tree

Community 1.1
shrubs - pioneer trees

This phase in characterized by pioneering woody species that respond rapidly to increased light availability. Cover is generally very heavy, but not usually very tall. As time and succession progress, the trees become larger and less dense.

Community 1.2
sugar maple - American beech

This phase in characterized by tree dominance, particularly sugar maple, beech and basswood. Additional canopy species include white oak, bitternut and shagbark hickory, and black walnut

Dominant plant species

sugar maple (Acer saccharum), tree
American beech (Fagus grandifolia), tree

Pathway P1.1A
Community 1.1 to 1.2

Time and succession will move the site from this phase to the full expression of Community Phase 1.2

Pathway P1.2A
Community 1.2 to 1.1

Disturbance, whether natural or as management, that removes a large portion of the trees will move the site towards phase 1.1

State 2
Invaded State

This state is characterized by the establishment and eventual dominance of invasive species in the understory. This greatly reduces the species richness and diversity of the site as a whole, but especially in the understory. Common invasive species for this site include, but are not limited to, species of Asian bush honeysuckle, Callery pear, and ailanthus.

Dominant plant species

sugar maple (Acer saccharum), tree
American beech (Fagus grandifolia), tree
honeysuckle (Lonicera), shrub
autumn olive (Elaeagnus umbellata), shrub

Community 2.1
sugar maple - American beech

This phase is characterized by the understory being dominated by woody, mostly non-native, invasive species.

Dominant plant species

sugar maple (Acer saccharum), tree
American beech (Fagus grandifolia), tree
autumn olive (Elaeagnus umbellata), shrub
honeysuckle (Lonicera), shrub

State 3
Agricultural State

This state is characterized by the conversion of the site to agricultural use. Most common practice is a corn and soybean rotation of various types. A small portion of the historic acres are used for forage and pasture.

Community 3.1
row crops - corn / soybeans

This phase is characterized by row crop agriculture, primarily corn and soybeans.

Community 3.2
cool season forage / pasture

This phase is characterized by forage or grazing agriculture. Different mixes of, generally, cool season grasses and forbs, largely clovers, are grown.

Pathway P3.1A
Community 3.1 to 3.2

Planting of cool season pasture/forage species and management to maintain them.

Pathway P3.2A
Community 3.2 to 3.1

Planting, either by conventional or no-till methods, of row crop. Management that keeps the site in row crop production

Transition T1A
State 1 to 2

The establishment of an invasive species without management to remove or control it will transition the site to the Invaded State (2).

Transition T1B
State 1 to 3

Removal of the trees and the installation of a drainage system are the first steps in converting the site to the Agriculture State (3). Regular agricultural practices will maintain the site in that state.

Restoration pathway R2A
State 2 to 1

Chemical and mechanical treatment of the invasive species. Planting of desired species may be needed if they are not enough left to recolonize the site.

Transition T2B
State 2 to 3

Removal of trees and other woody species. Install drainage system (if warranted), prepare the site for planting the agricultural crop, and regular agricultural practices.

Restoration pathway R3A
State 3 to 1

Removal of drainage system (if warranted), site preparation, and tree planting.

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.
