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

A PROVISIONAL ECOLOGICAL SITE is a conceptual grouping of soil map unit components within a Major Land Resource Area (MLRA) based on the similarities in response to management. Although there may be wide variability in the productivity of the soils grouped into a Provisional Site, the soil vegetation interactions as expressed in the State and Transition Model are similar and the management actions required to achieve objectives, whether maintaining the existing ecological state or managing for an alternative state, are similar. Provisional Sites are likely to be refined into more precise group during the process of meeting the APPROVED ECOLOGICAL SITE DESCRIPTION criteria.

This PROVISIONAL ECOLOGICAL SITE has been developed to meet the standards established in the National Ecological Site Handbook. The information associated with this ecological site does not meet the Approved Ecological Site Description Standard, but it has been through a Quality Control and Quality Assurance processes to assure consistency and completeness. Further investigations, reviews and correlations are necessary before it becomes an Approved Ecological Site Description.

111C – Indiana and Ohio Till Plain, Northwestern Part. This MLRA is in the glaciated part of north-central Indiana and is dominated by glacial till plains broken in places by lake plains, outwash plains, and flood plains. Areas that parallel most of the major rivers and streams have deposits of sand.

Although it is an important agricultural region, MLRA 111C hosts a large proportion of Indiana’s biodiversity.

Ecological site concept

This site is an upland site form on sandy, wind and water deposited, parent materials. It is located on the summits, shoulders, and steep back slopes of dune topography. There are 3 distinct states: 1. dry sand savanna (reference state), 2. black oak woodland, and 3 agriculture state. Fire frequency and intensity were the principle drivers between the first two states. Currently, over 80% of this site is in the agriculture state and mostly used for corn and soybean production.

Ecological dynamics

The historic plant community of the Sand Dune ecological site is a dry sand savanna. This site is characterized by the ebb and flow of the co-dominant tall grass prairie species and oak species, primarily black oak. This dynamic was driven by the fire frequency and intensity.

The canopy tree cover varied from about 5 to 60 percent and dominated by black oak. Other prominent tree species include white oak, black cherry, and hickory species. The ground layer is dominated by graminoids with the most common species being little bluestem, porcupine grass, and big bluestem.

Ground fires was the most common disturbance for this site. These frequent, but lower intensity fires, in conjunction with wind throw would maintain the function of the site. Replacement fires would have occurred roughly every 200 years.

Since settlement, the majority of this site (80%) has been converted to agricultural use with the majority being row crop agriculture. The most common practice involves grain rotations between corn and soybeans, with occasionally wheat being planted.

State and transition model

More interactive model formats are also available. View Interactive Models
Click on state and transition labels to scroll to the respective text

State 1
Dry Sand Savanna

This is the reference or diagnostic plant community for this site. In reference condition, this site was a co-dominance of prairie grass species and black oaks. Fire was the main disturbance agent that maintained the site. The more recent the fire the greater the dominance of grasses. Longer time between fire would sway dominance towards the black oak trees. The removal of fire from the system and lack of tree management would move the site toward the black oak woodland state. Restoration back to the reference state could be accomplished with timber harvest, seeding of appropriate species, and the application of fire. Plowing the prairie portions up,removing the trees, and preparation for seeding for would transition the site to the agriculture state. Cessation of tillage practices, seeding the proper species and the application of fire would allow the agriculture state to return to the reference state.

Community 1.1
little bluestem/black oak/porcupine grass

This phase is characterized by recent or frequently occurring ground fires that shift the co-dominance towards the herbaceous species. Longer fire return intervals will move this towards phase 2.

Community 1.2
black oak/little bluestem

This phase is characterized by protection from or longer time since the last fire. Trees and herbaceous species are co-dominant during this phase. More frequent/intense fire will shift this phase back to phase 1. Increased fire absence and no woody species management will move this site toward State 2, characterized by the marked increase in shrubs.

State 2
Black Oak Woodland

Absence of fire and/or lack of woody vegetation management will move this site to the black oak woodland state. This state is characterized by an increase in tree canopy (61-100%) concomitant with shrub species becoming the dominant growth form in the understory. Black oaks will still be the dominant tree species, but white oaks and hickory become more dominant. Sub canopy and shrub species include the dogwood species, sassafras, and hazelnut species. Continued suppression of disturbance will lead to this site being a closed canopy oak-dominated forest at the higher end of the suggested canopy range. White oak eventually becomes the dominant tree species with black oak, shagbark hickory and black cherry also in the canopy.

Community 2.1
black oak/shrub/few prairie species

This phase is characterized by protection from or longer time since the last fire. Trees are the dominant growth form and shrubs are the secondary growth form. Timber cutting, more frequent/intense fire, and seeding will transition this phase back to State 1. Increased fire absence and no woody species management will move this site toward phase 2, characterized by shift in tree species.

Community 2.2
black oak/white oak/ hickory

This phase is characterized by near lack of fire. Trees are the dominant growth form. White oaks and hickory species become more common/prevalent in the canopy. Timber cutting, more frequent/intense fire, and seeding will transition this phase back to phase 1.

State 3
Agriculture

This site has largely been converted to agricultural use. Roughly 75% of the historic acres are now in row crop agricultural use. Most common is a corn and soybean rotation of various types. Roughly 5% of the site is not used to grow hay or cool season forage and used for grazing.

Community 3.1
Row Crop Agriculture

This phase is characterized by row crop agriculture of small grains, primarily corn, soybeans, and occasionally wheat. Seeding and management could transition this phase to phase 2.

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. Tillage, seeding and management could transition this phase to phase 1.

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.
