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.

Ecological site concept
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”.
Sandy/Gravelly Floodplain Forests occur throughout the Ozark Highland along most streams. Soils are very gravelly, and subject to flooding. The reference plant community is a forest dominated by sycamore and eastern cottonwood.

Physiographic features
This site is on floodplains with slopes of 0 to 3 percent. This ecological site is generally on the lowest floodplain directly adjacent to the stream channel, but also occurs along abandoned channels farther from the active stream channel. The site receives some runoff from higher floodplains, stream terraces and uplands. This site is subject to frequent flooding.
The following figure (adapted from Simmons et al, 2006) shows the typical landscape position of this ecological site, and landscape relationships with other ecological sites. It is within the area labeled “5” on the figure, directly adjacent to the stream channel. Sandy/Gravelly Floodplain Forest sites are typically associated with Floodplain Step sites, labeled “4”, and with Terrace sites, labeled “3”.

Climatic features
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 typically in natural levee positions directly adjacent to a perennial stream. Stream levels typically respond quickly to storm events, especially in watersheds where surface runoff is dominant. Short- to medium- duration flooding is common in many areas, particularly during spring and early summer storm events. Constructed levees, often accompanied by stream channelization, have altered the hydrology and flooding dynamics in many places.
This site is in the RIVERINE class of the Hydrogeomorphic (HGM) classification system (Brinson, 1993). The stream hydrograph drives the inflows and outflows of RIVERINE wetlands. Water moves into floodplain wetlands as surface water during flood stage, or as groundwater exchange from the stream channel to the floodplain during high flow stages. As the flood stage recedes, surface and groundwater return to the channel. The direction of movement is horizontal. The direction is also bi-directional in the lateral axis across the floodplain but is unidirectional on the longitudinal axis parallel to the valley as water flows downhill along the valley gradient. In floodplains with high permeability sands and gravels, the volume of flow in the lateral and longitudinal directions is quite large and can exceed the volume of stream flow in the active channel.
Cowardin wetland types (Cowardin et al., 1979), include: Palustrine Emergent Temporarily Flooded and Seasonally Flooded
Soil features
These soils have low plant-available water capacity, due to an abundance of coarse fragments. They were formed under forest vegetation, with periodic depositional flood events. Organic matter content is variable. Parent material is alluvium. They have sandy loam, loam or silt loam surface horizons that are gravelly to very gravelly in places, and sandy or loamy subsoils that are generally skeletal. They are not affected by seasonal wetness. Soil series associated with this site include Batcave, Bloomsdale, Cedargap, Elsah, Huzzah, Kaintuck, Midco, Perche, Pinerun, Relfe, Riverwash, Sandbur, Tilk, and Wideman.

Ecological dynamics
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.
Interior Ozark streams are generally high-gradient, with frequent, flashy floods after significant rainfall events. Flooding of Sandy/Gravelly Floodplain Forests typically occurs annually or at least once every three years. Cherty gravel and sandy sediments, originating from the predominance of cherty dolomites and sandstone strata in the surrounding uplands, make up a significant portion of the alluvium in most Interior Ozark floodplains. These materials are normally deposited near the stream where fast-moving waters can carry and release them. Gravel bar succession to forest is dominated by flood tolerant, pioneer tree species such as sycamore, eastern cottonwood and willow. Young stands of these species stabilize the floodplain gravel bars, and continue to trap coarse-textured floodwater sediments.
Consequently, many Sandy/Gravelly Floodplain Forests tend to be even-aged. Young stands are often dense, with a sparse understory and ground flora. As the forest matures, canopy gaps provide more light, finer sediments accumulate on the forest floor, and a dense ground flora of grasses and nettles develops. Over time, the local stream may down-cut into the floodplain or meander away from the site, thereby altering the flooding regime. The lower frequency of floods and slower floodwaters results in deposition of loamy sediments. Ultimately, shade tolerant elm, ash, and hackberry will accumulate in the understory and the forest may succeed to a Loamy Floodplain Forest ecological site dominated by these species. However, catastrophic floods will often partially or completely knock down the early successional species and regenerate the ecological site. Consequently, this site is typically a mosaic of early to late successional floodplain forest.
Today many Sandy/Gravelly Floodplain Forests in Missouri have been cleared and converted to agriculture and are often cleared right up to the bank. In such cases, severe flooding may cause stream bank erosion and complete loss of this ecological site. Grazing by domestic livestock in the remaining strips of forest, can also kill trees and remove the ground cover, resulting in de-stabilization and potential loss of this ecological site as well.
Remaining remnants still exist along un-leveed areas and within levees. They often occur as a rather narrow band of trees and shrubs traversing the stream edge. These bands of forest play an important role as a source of food and shelter for migrating birds. In addition, isolated large sycamore and cottonwood trees that rise above the canopy are important nesting sites for bald eagles and herons.
Re-establishment of these riparian forests is important for stream quality and health, as well as for migratory birds. Planting of early successional pioneer species on these sites has proven to be quite successful.
A State and Transition Diagram follows. Detailed descriptions of each state, transition, plant community, and pathway follow the model.

Reference
Sandy/Gravelly Floodplain Forests are dominated by mature sycamore and/or eastern cottonwood. While these species can occur together, sycamores tend to dominate the smaller, higher energy streams with more gravel, while cottonwoods are more dominant on larger rivers with less gravel. Maximum tree age, historically, was probably about 100 years. However, patches of younger, early successional trees and shrubs occur mainly along the flood-prone edges or interior high-water channels of the mature forest. Willows are common in the younger patches and persist along the edges of the mature forest where there is more light. Younger patches tend to occur on recently deposited sands and gravels, and have a sparse understory. These gravel bars and intermittent stream channels are in the early stages of ecological succession, and are typically on point bar deposits. They are characterized by a sparse to abundant ground cover of grasses and forbs. Shrubs such as coastal plain willow, Ozark witchhazel and common ninebark can create a 100 percent cover in places, and tree seedlings of cottonwood are common. Frequent, high-velocity flood events deposit fresh sand and gravel in places, often derived from stream bank erosion of upstream sites in States 2 or 3. Other places are scoured by these flood events. As the stream meanders farther away from these sites, flooding events decrease in frequency and intensity, and the state will gradually develop into the early seral Sandy/Gravelly Floodplain Forest community. Mature forest phases have a more stable surface with a dense ground flora of wildrye, spikegrass and nettle. Dense tangles of vines can also occur, especially associated with canopy gaps. Slippery elm, green ash and hackberry also succeed into the canopy gaps.

State 2
High-Graded/Grazed Forest
Sandy/Gravelly Floodplain Forest reference sites subjected to repeated, high-graded timber harvests and domestic grazing transition to this state. This state exhibits an over-abundance of less desirable tree species, and weedy understory species such as coralberry. The vegetation offers little nutritional value for cattle, and excessive stocking damages tree boles, degrades understory species composition, destabilizes stream banks and results in soil compaction and accelerated erosion and runoff during flood events. Restoration of the riverfront forest can be facilitated by exclusion of cattle coupled with tree planting.
Community 2.1
Sycamore – Eastern Cottonwood – Willow/Coralberry
State 3
Cool Season Grassland
Conversion of Sandy/Gravelly Floodplain Forest ecological sites to planted, non-native pasture species such as tall fescue can occur in the Ozark highlands. Frequent flooding and low available water capacity make non-native pastures difficult to maintain in a healthy, productive state on this ecological site. Restoration of the Sandy/Gravelly Floodplain Forests can be achieved over time by discontinuing grazing and active pasture management and allowing natural woody succession to occur. Tree planting, especially to bring in desired species, may be necessary.
Community 3.1
Tall Fescue/Red Clover
This is an herbaceous community that is typically dominated by tall fescue. Various other grass and forb species are typically present, in various amounts. Shrub and pioneer tree species such as sycamore and cottonwood typically invade sites that are not regularly managed.

Other information
Forestry (NRCS 2002, 2014):
Management: Field measured site index values range from 47 to 66 for oak and 57 to 90 for non-oak species. Timber management opportunities are good. Create group openings of at least 2 acres. Large clearcuts should be minimized if possible to reduce impacts on wildlife and aesthetics. Uneven-aged management using single tree selection or small group selection cuttings of ½ to 1 acre are other options that can be used if clear cutting is not desired or warranted. Maintain adequate riparian buffer areas.
Limitations: Wetness from short duration flooding; coarse fragments in profile. The use of equipment may be restricted in spring and other excessively wet periods. Disturbing the surface excessively in harvesting operations and building roads increases soil losses, which may leave a greater amount of coarse fragments on the surface. Tree planting is difficult during spring flooding periods. Mechanical tree planting may be limited due to coarse fragments on surface.

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.

Indicators
-
Number and extent of rills:
-
Presence of water flow patterns:
-
Number and height of erosional pedestals or terracettes:
-
Bare ground from Ecological Site Description or other studies (rock, litter, lichen, moss, plant canopy are not bare ground):
-
Number of gullies and erosion associated with gullies:
-
Extent of wind scoured, blowouts and/or depositional areas:
-
Amount of litter movement (describe size and distance expected to travel):
-
Soil surface (top few mm) resistance to erosion (stability values are averages - most sites will show a range of values):
-
Soil surface structure and SOM content (include type of structure and A-horizon color and thickness):
-
Effect of community phase composition (relative proportion of different functional groups) and spatial distribution on infiltration and runoff:
-
Presence and thickness of compaction layer (usually none; describe soil profile features which may be mistaken for compaction on this site):
-
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:
