MLRA notes
Major Land Resource Area (MLRA): 116A–Ozark Highland
The Ozark Highland constitutes the Salem Plateau of the Ozark Uplift. Elevation ranges from about 300 feet on the southeast edge of the Ozark escarpment, to about 1,600 feet in the west, adjacent to the Burlington Escarpment of the Springfield Plateau. The underlying bedrock is mainly horizontally bedded Ordovician-aged dolomites and sandstones that dip gently away from the uplift apex in southeast Missouri. Cambrian dolomites are exposed on deeply dissected hillslopes. In some places, Pennsylvanian and Mississipian sediments overlie the plateau. Relief varies, from the gently rolling central plateau areas to deeply dissected hillslopes associated with drainageways such as the Buffalo, Current, Eleven Point and White Rivers.

NOTE: This is a “provisional” Ecological Site Description (ESD) that is under development. It contains basic ecological information that can be used for conservation planning, application and land management. After additional information is collected, analyzed and reviewed, this ESD will be refined and published as “Approved”.
Claypan Summit Prairies occur primarily in the northwest part of the Ozark Highland. Soils have root-limiting claypans or root-restricting fragipans, and seasonal perched water tables. The reference plant community is prairie dominated by Indiangrass, big bluestem, little bluestem and sideoats grama with a wide variety of prairie wildflowers and wet-tolerant sedges.Associated sites

The Ozark Highland has a continental type of climate marked by strong seasonality. In winter, dry-cold air masses, unchallenged by any topographic barriers, periodically swing south from the northern plains and Canada. If they invade reasonably humid air, snowfall and rainfall result. In summer, moist, warm air masses, equally unchallenged by topographic barriers, swing north from the Gulf of Mexico and can produce abundant amounts of rain, either by fronts or by convectional processes. In some summers, high pressure stagnates over the region, creating extended droughty periods. Spring and fall are transitional seasons when abrupt changes in temperature and precipitation may occur due to successive, fast-moving fronts separating contrasting air masses.
The Ozark Highland experiences regional differences in climates, but these differences do not have obvious geographic boundaries. Regional climates grade inconspicuously into each other. The basic gradient for most climatic characteristics is along a line crossing the MLRA from northwest to southeast.
The average annual precipitation in almost all of this area is 38 to 45 inches. Snow falls nearly every winter, but the snow cover lasts for only a few days. The average annual temperature is about 53 to 60 degrees F. The lower temperatures occur at the higher elevations in the western part of the MLRA. Mean January minimum temperature follows a stronger north-to-south gradient. However, mean July maximum temperature shows hardly any geographic variation in the MLRA. Mean July maximum temperatures have a range of only two or three degrees across the area.
Mean annual precipitation varies along a northwest to southeast gradient. Seasonal climatic variations are more complex. Seasonality in precipitation is very pronounced due to strong continental influences. June precipitation, for example, averages three to four times greater than January precipitation. Most of the rainfall occurs as high-intensity, convective thunderstorms in summer.
During years when precipitation comes in a fairly normal manner, moisture is stored in the top layers of the soil during the winter and early spring, when evaporation and transpiration are low. During the summer months the loss of water by evaporation and transpiration is high, and if rainfall fails to occur at frequent intervals, drought will result. Drought directly affects plant and animal life by limiting water supplies, especially at times of high temperatures and high evaporation rates.
Superimposed upon the basic MLRA climatic patterns are local topographic influences that create topoclimatic, or microclimatic variations. In regions of appreciable relief, for example, air drainage at nighttime may produce temperatures several degrees lower in valley bottoms than on side slopes. At critical times during the year, this phenomenon may produce later spring or earlier fall freezes in valley bottoms. Deep sinkholes often have a microclimate significantly cooler, moister, and shadier than surrounding surfaces, a phenomenon that may result in a strikingly different ecology. Higher daytime temperatures of bare rock surfaces and higher reflectivity of these unvegetated surfaces may create distinctive environmental niches such as glades and cliffs.
Slope orientation is an important topographic influence on climate. Summits and south-and-west-facing slopes are regularly warmer and drier than adjacent north- and-east-facing slopes. Finally, the climate within a canopied forest is measurably different from the climate of a more open grassland or savanna areas.

">Influencing water features
This ecological site is influenced by a seasonal high water table, perched on the clayey subsoil. Some depressional areas pond for short periods of time, mostly in the spring. These shallow depressional areas were more common prior to the conversion of nearly all areas of this ecological site from prairie to cropland. Leveling and surface drainage have reduced or eliminated the shallow depressions. These areas were Emergent Palustrine wetlands (Cowardin et al., 1979).<br />
<br />
This ecological site contains wetlands which fit into the MINERAL FLAT class in the Hydrogeomorphic (HGM) system (Brinson, 1993). The water source is direct precipitation, because there are no upslope contributing sites. Vertical water percolation in the soil is impeded by the clayey subsoil (the “claypan”), resulting in significant lateral discharge to adjacent downslope ecological sites. Adjacent sites include Headwater SLOPE HGM class sites in watershed headwaters. This discharge supports surface saturation in the adjacent areas. <br />
<br />
In general, MINERAL FLAT areas provide watershed recharge and runoff that accumulates in downslope reaches as groundwater discharge and surface water accumulation. Wetland hydrology is effectively removed by surface ditches or subsurface tile drainage that directs vertical downward movement in a horizontal direction to the drainage element. Wetland hydrology is also influenced by the surface storage afforded by vegetation and natural surface roughness. This storage is a large part of the water budget, allowing the profile to be re-filled with water which would otherwise run off. In extreme cases, conversion to agriculture can completely remove wetland hydrology.Soil features
These soils have either a fragipan at about 24 inches, or an abrupt textural change to silty clay or clay at about 18 inches, or a clayey subsoil that is similar to an abrupt textural change. Fragipans stop most roots, whereas abrupt textural changes impede but do not exclude rooting. The soils were formed under prairie vegetation, and have dark, organic-rich surface horizons. They have silt loam surface horizons, and silty clay to clay subsoils. Parent material is mainly loess. Some soils are underlain with residuum derived from limestone. A seasonal high water table is perched above the fragipan or abrupt textural change during the spring months in most years. Soil series associated with this site include Crestmeade, Gerald, Glensted, Leslie and Rosati.
The accompanying picture of the Glensted series shows a dark silt loam surface horizon over the claypan, a clay horizon that impedes water movement and root penetration. Indicators of seasonal wetness (redoximorphic features) are visible in the lower part of the profile. Photo credit NRCS.

Information contained in this section was developed using historical data, professional experience, field reviews, and scientific studies. The information presented is representative of very complex vegetation communities. Key indicator plants, animals and ecological processes are described to help inform land management decisions. Plant communities will differ across the MLRA because of the naturally occurring variability in weather, soils, and aspect. The Reference Plant Community is not necessarily the management goal. The species lists are representative and are not botanical descriptions of all species occurring, or potentially occurring, on this site. They are not intended to cover every situation or the full range of conditions, species, and responses for the site.
Claypan Summit Prairies were dominated by tallgrass prairie grasses and forbs, but also had a substantial component of wet tolerant sedges. This expanse of grass occurred on upland summit interfluves and divides and was interrupted by shallow drainages whose wetness lessened the influence frequent, intense fires. Here the prairie transitioned into shrubby thickets and savannas with scattered trees. Leadplant and New Jersey tea were typical low growing shrubs that occurred over the site. Unlike most shrubs, these plants are both quite tolerant to fire. Islands of other shrubs such as dogwood, coralberry and Carolina rose were also found on the site.
With little to interrupt fire, this ecological site burned every 1 to 3 years. Fire removed dead plant litter and provided room for a lush growth of prairie vegetation. Fire also kept woody species at bay.
Grazing by native large herbivores, such as bison, elk, and white-tailed deer, also impacted these sites. Their activities would have altered composition and structure of the vegetation. Fuel loads would have been altered by heavy grazing and fire behavior affected, providing for a diversity of structure and composition. The partially wooded draws would have burned less intensely and frequently. During fire free intervals woody species would have increased in abundance and spread out onto the prairie.
Today, Claypan Summit Prairies are nearly extirpated from the region as the former prairies have been converted to intensive agriculture. Few known remnants exist and those remaining are degraded by fire suppression and grazing by domestic livestock.
A state-and-transition model diagram follows. Detailed descriptions of each state, transition, plant community, and pathway follow the model. This model is based on available experimental research, field observations, professional consensus, and interpretations. It may change as knowledge increases.State and transition model

State 1
ReferenceThis state is native tall grass prairie dominated by little bluestem, big bluestem and forbs, but also a substantial component of wet tolerant sedges. This state occurs on level to gently sloping soils that have a seasonal high water table that is perched above the abrupt textural change or clayey subsoil during the spring months in most years. This condition influences the species composition and site productivity. Two phases can occur that will transition back and forth depending on fire frequencies. Longer fire free intervals will allow woody species to increase such as gray dogwood and eastern redcedar. When fire intervals shorten these woody species will decrease.
This state is extremely rare. Nearly all remaining sites have been converted to cool season grassland, cropland, or have been degraded through uncontrolled domestic livestock grazing.Community 1.1

Community 1.2
Gray Dogwood/ Prairie Dropseed – Big BluestemTwo phases can occur that will transition back and forth depending on fire frequencies. Longer fire free intervals will allow woody species to increase such as gray dogwood and eastern redcedar. When fire intervals shorten these woody species will decrease.
Pathway P1.1A
Community 1.1 to 1.2This pathway results from fire suppression. With fire-free intervals of 10 to 20 years, woody species will increase in density and cover causing the community to gradually shift to phase 1.2 . Some displacement of grasses and forbs may be occurring due to shading, competition from the increased densities of shrubs, and increased thatch build up.
Pathway P1.2A
Community 1.2 to 1.1With increased fire frequencies, woody species will decrease in density and cover and over time this community will gradually shift back to community phase 1.1. Production levels will generally increase.
State 2
Woody Invaded SavannaDegraded reference states that have experienced fire suppression for 20 or more years will transition to this state. With fire suppression, woody species such as pin oak and eastern redcedar will begin to dominate transitioning this state from a prairie to a Woody Invaded Savanna. Native ground cover will also decrease and invasive species such as tall fescue may begin to dominate.
Community 2.1
Post Oak – Eastern Redcedar /American Plum/Little BluestemState 3
Cool Season GrasslandConversion of other states to non-native cool season species such as tall fescue and red clover has been common. Occasionally, these pastures will have scattered oak. Long term uncontrolled grazing can cause significant soil erosion and compaction. A return to the reference state may be impossible, requiring a very long term series of management options.
Community 3.1
Tall Fescue-Red CloverState 4
CroplandThis is the dominant state that exists currently with intensive cropping of corn, soybeans, and wheat occurring. Some conversion to non-native cool season grassland occurs for a limited period of time before transitioning back to cropland. Limited acres are sometimes converted to native warm season grassland.
Community 4.1
Corn, Soybean, WheatState 5
Native Warm Season GrasslandConversion from the Cool Season Grassland (State 3) or the Cropland (State 4) to this state is increasing due to renewed interest in warm season grasses as a supplement to cool season grazing systems or as a native restoration activity. This state is the most easily transformable state back to a reference state. Substantial restoration time and management inputs will be needed.

Functional/Structural Groups (list in order of descending dominance by above-ground annual-production or live foliar cover using symbols: >>, >, = to indicate much greater than, greater than, and equal to):
Dominant:
Sub-dominant:
Other:
Additional:
-
Amount of plant mortality and decadence (include which functional groups are expected to show mortality or decadence):
-
Average percent litter cover (%) and depth ( in):
-
Expected annual annual-production (this is TOTAL above-ground annual-production, not just forage annual-production):
-
Potential invasive (including noxious) species (native and non-native). List species which BOTH characterize degraded states and have the potential to become a dominant or co-dominant species on the ecological site if their future establishment and growth is not actively controlled by management interventions. Species that become dominant for only one to several years (e.g., short-term response to drought or wildfire) are not invasive plants. Note that unlike other indicators, we are describing what is NOT expected in the reference state for the ecological site:
-
Perennial plant reproductive capability:
