MLRA notes

Major Land Resource Area (MLRA): 111X–Indiana and Ohio Till Plain

111B – Indiana and Ohio Till Plain, Northeastern Part. This area is in the Eastern Lake and Till Plains Sections of the Central Lowland Province of the Interior Plains. The entire MLRA is glaciated, and most areas are dominated by ground moraines that are broken in places by lake plains, outwash plains, flood plains, and many recessional moraines. The ground moraines and lake plains in front of the recessional moraines are flat to undulating. In many places stream valleys occur at the leading edge of the recessional moraines. Narrow, shallow valleys commonly are along the major rivers and streams in this MLRA, and some areas along the major rivers and streams have deposits of sand. Elevation ranges from 630 to 1,550 feet (190 to 470 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 plains.

The extent of the major Hydrologic Unit Areas (identified by four-digit numbers) that make up this MLRA is as follows: Western Lake Erie (0410), 41 percent; Wabash (0512), 28 percent; Scioto (0, 28 percent; Scioto (0506), 10 percent; St. Clair-Detroit (0409), 9 percent; Great Miami (0508), 6 percent; Southeastern Lake Michigan (0405), 5 percent; and Southwestern Lake Huron (0408), 1 percent. The Huron River in Michigan, Cedar Creek in Indiana, and the Sandusky River in Ohio have been designated as National Wild and Scenic Rivers in this MLRA.

The surficial materials in this area include glacial deposits of till, outwash, and lacustrine sediments from Wisconsin and older glacial periods. A thin mantle of loess occurs in some areas. Most of the MLRA is underlain by Silurian and Devonian limestone and dolostone. Middle Devonian to Early Mississippian black shale and Early to Middle Mississippian siltstone and shale are in some areas of the northern part of the MLRA.

Ecological site concept

This site is an upland site generally formed on residuum weathered from sandstone overlain with till or loess. The depth to the restrictive layer is between 20 to 40 inches. Drainage is somewhat poorly drained with slopes generally from 0-3%. The characteristic vegetation of this site is that of a forest comprised largely of fire sensitive, shade tolerant species. The dominant canopy level species include sugar maple, American beech, and tulip tree. Gap phase regeneration is the most common disturbance dynamic on the site and allows these species to reach the canopy. Wind throw and ice storms are larger scale disturbance mechanisms, but they incur very infrequently. The site can be susceptible to the establishment and dominance of the understory by woody, invasive, non-native species. Most of this historically woodland site is now being for agriculture to include hay, pasture, and row crops.

Ecological dynamics

The historic plant community of the Deep Restricted ecological site is a forest with the dominant species in the canopy being sugar maple, beech, and tulip-tree. Canopy associates include white oak, shagbark hickory, hackberry 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. Since settlement, parts of this site have been converted to agricultural use with the majority being to grow hay or used as pasture. The areas still in natural vegetation are at risk of having their understory invaded and dominated by invasive species such as Asian honeysuckles and even Callery pear.

State 1
Mesic Forest

This is the diagnostic plant community for this site. In reference condition, this site was dominated by sugar maple, beech, and tulip-tree. An earlier successional phase of this site is comprised largely of shrubs and pioneering species. 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
tuliptree (Liriodendron tulipifera), 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.

Dominant plant species

sugar maple (Acer saccharum), tree
tuliptree (Liriodendron tulipifera), tree

Community 1.2
sugar maple - beech

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

Dominant plant species

sugar maple (Acer saccharum), tree
tuliptree (Liriodendron tulipifera), 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. Common invasive species for this site include, but are not limited to, species of Asian bush honeysuckle, Callery pear, autumn olive and ailanthus.

Dominant plant species

sugar maple (Acer saccharum), tree
American beech (Fagus grandifolia), tree
tuliptree (Liriodendron tulipifera), tree
honeysuckle (Lonicera), shrub
autumn olive (Elaeagnus umbellata), shrub
tree of heaven (Ailanthus altissima), shrub
Callery pear (Pyrus calleryana), shrub

Community 2.1
sugar maple - beech / invasive understory

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
tuliptree (Liriodendron tulipifera), tree
autumn olive (Elaeagnus umbellata), shrub
Callery pear (Pyrus calleryana), shrub
honeysuckle (Lonicera), shrub
tree of heaven (Ailanthus altissima), shrub

State 3
Agricultural State

This state is characterized by the conversion of the site to agricultural use. Most typical practice is to grow forage and pasture, but corn and soybean rotations of various types are common as well.

Community 3.1
Corn - soybeans cropland

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

Community 3.2
cool season grasses pasture/ forage

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

Establishment of invasive species with not management to control them will move the site towards the Invaded State.

Transition T1B
State 1 to 3

The site is converted to the Agriculture State (#3) after the woody species are removed, the crops planted, and implementation of agricultural practices.

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 T2A
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.
