MLRA notes
Major Land Resource Area (MLRA): 115X–Central Mississippi Valley Wooded Slopes
The Central Mississippi Valley Wooded Slopes, Western Part (area outlined in red on the map) consists mainly of the deeply dissected, loess-covered hills bordering the Missouri and Mississippi Rivers as well as the floodplains and terraces of these rivers. It wraps around the northeast corner of the Ozark Uplift, and constitutes the southern border of the Pre-Illinoisan-aged till plain. Elevation ranges from about 320 feet along the Mississippi River near Cape Girardeau in the south to about 1,020 feet on the highest ridges near Hillsboro, MO in the east. Local relief varies from 10 to 20 feet in the major river floodplains, to 50 to 100 feet in the dissected uplands, with bluffs of 200 to 350 feet along the Mississippi and Missouri Rivers. Underlying bedrock is mainly Ordovician-aged dolomite and sandstone, with Mississippian-aged limestone north of the Missouri River.

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/Loamy Floodplain Forests (green areas on the map) are on the Missouri River and Mississippi River floodplains, primarily adjacent to the current river channel. Sites are commonly adjacent to the Clayey Floodplain Forest ecological sites. Soils are very deep, and are sandy to very fine sandy loam throughout. The reference plant community is forest dominated by black willow, eastern cottonwood, hackberry, river birch, sycamore, silver maple, and American elm.

Climatic features
The Central Mississippi Valley Wooded Slopes, Western Part 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 Central Mississippi Valley Wooded Slopes, Western Part 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 diagonally crossing the MLRA from northwest to southeast. Both mean annual temperature and precipitation exhibit gradients along this line.
The average annual precipitation in most of this area is 38 to 48 inches. The average annual temperature is 53 to 57 degrees F. Mean January minimum temperature follows the northwest-to-southeast 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 the same gradient as temperature. 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. Snowfall is common in winter.
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. 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 wetlands 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 uni-directional on the longitudinal axis parallel to the valley as water flows downhill along the valley gradient.
Soil features
These soils are very deep and coarse-textured throughout, with moderate to low plant-available water capacity. The soils were formed under woodland vegetation, and have thin, light-colored surface horizons. Parent material is alluvium. They have very fine sandy loam to fine sand surface layers, with calcareous subsurface layers that range from very fine sandy loam to sand. These soils are not affected by seasonal wetness. Soil series associated with this site include Blake, Buckney, Carr, Dozaville, Eudora, Grable, Haynie, Hodge, Kenmoor, Landes, Lowmo, Peers, Rocher, Sarpy, Treloar, and Ware.

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.
The Missouri and Mississippi rivers are a very dynamic system with frequent flooding and multiple braided channels shifting back and forth across the floodplain. Loamy, coarse loamy and sandy deposits of sediment were common, occurring along the floodplains with the sandy materials the youngest and most recently deposited substrate in this matrix. This ecological site is located on former streamside areas where frequent swift currents dumped the heavier sandy sediment load next to the river. It is normally surrounded by Loamy or Clayey Floodplain Forests on slightly lower areas.
Flooding of Sandy/Loamy Floodplain Forest occurred annually or at least once every 3 years. Sand bar succession to forest is dominated by flood tolerant, pioneer tree species such as willow and cottonwood. Young stands of these species tend to stabilize the riverfront floodplain and continue to accumulate coarse materials. Consequently, many Sandy/Loamy 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 while more fine sediments accumulate on the forest floor, resulting in a dense ground flora of grasses and nettles.
Over the long term, these sites become elevated and isolated and begin to accumulate even more fine sediments. Ultimately, shade tolerant elm, ash, and hackberry will accumulate in the understory and the forest may resemble a Loamy Floodplain Forest dominated by these species. However, catastrophic floods will often partially or completely knock down the early successional species and regenerate this ecological system. Consequently, this ecological site is often made up of a mosaic of early to late successional floodplain sandy and loamy forests.
Today many floodplains of these forests have been cleared and converted to agriculture, often right up to the bank. In such cases, severe flooding may cause stream bank erosion and complete loss of this ecological site.
Remaining remnants still exist along un-leveed areas, within levees and on islands. 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. This model is based on available experimental research, field observations, professional consensus, and interpretations. It is likely to change as knowledge increases.

State 1
Reference
Maximum tree age, historically, was probably about 100 to 150 years. A tall, uneven canopy of 80 to 100 feet tall, with occasional gaps and a closure of 80 to 100 percent is the dominant feature of this ecological site. 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 coarser materials, and have a sparse understory. They are characterized by a sparse to abundant ground cover of grasses and forbs. Shrubs can create a 100 percent cover in places, and tree seedlings of cottonwood are common. Frequent, high-velocity flood events deposit fresh alluvium 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 change back into 1.1 phase community. Mature forest phases have a more stable surface with a dense ground flora of wild rye, spike grass and nettles. Dense tangles of vines can also occur, especially associated with canopy gaps. Red elm, green ash and hackberry also succeed into the canopy gaps.
Community 1.1
Eastern Cottonwood – Hackberry/ Willow/ Wildrye
This community phase is characterized by frequent flood events which impact on the canopy structure and species composition. Flood-tolerant species such as sycamore, eastern cottonwood, green ash and hackberry are common.
Forest overstory. The Overstory Species list is based on field surveys and commonly occurring species listed in Nelson (2010).
Forest understory. The Understory Species list is based on field surveys and commonly occurring species listed in Nelson (2010).
Community 1.2
Sycamore – Eastern Cottonwood/Willow – Ninebark / Canadian Woodnettle
Over the long term, this phase becomes elevated and isolated and begins to accumulate more fine sediments. Ultimately, shade tolerant elm, ash, and hackberry will accumulate in the understory and the forest may resemble a Loamy Floodplain Forest dominated by these species.
State 2
Cropland
Conversion of reference states to cropland that is planted to corn, soybeans, or wheat has been common, especially on the more loamy areas. Frequent flooding and scouring can make this cropland state difficult to maintain in a healthy, productive state.
Community 2.1
Corn, Soybeans, Wheat
This is a common phase that exists currently with intensive cropping of corn, soybeans, and wheat occurring. Some conversion to cool season grassland occurs for a limited period of time before transitioning back to cropland.
State 3
Cool Season Grassland
Conversion of reference states to planted, non-native pasture species such as tall fescue has been common. Frequent flooding and areas with lower available water capacity make non-native pastures difficult to maintain in a healthy, productive state on this ecological site.
Community 3.1
Tall Fescue/Clover
This phase is a well managed grassland, composed of non-native cool season grasses and legumes. Grazing and haying is occurring. The effects of long-term liming on soil pH, and calcium and magnesium content, is most evident in this phase. Studies show that these soils have higher pH and higher base status in soil horizons as much as two feet below the surface, relative to poorly managed grassland and to woodland communities (where liming is not practiced).
Transition T1B
State 1 to 2
This transition is the result of poorly planned, high-grade timber harvest coupled with uncontrolled cattle access and grazing.
Transition T1A
State 1 to 3
This transition is the result of clearing the forest community and planting pasture species or crops.
Restoration pathway R2A
State 2 to 1
The Riverfront Forest can be restored if cattle are excluded from the forest, timber harvest is discontinued and timber stand improvement, including tree planting, is implemented.
Transition T2B
State 2 to 3
This transition is the result of clearing the forest community and planting pasture species or crops.
Restoration pathway R3A
State 3 to 1
The Early Seral Riverfront Forest can be restored if pasture management and grazing are terminated and tree planting is implemented.

Interpretations
Animal community
Wildlife (MDC 2006):
Tall emergent sycamores and cottonwoods along with an uneven canopy structure and canopy gaps are important for heron colonies, eagle nesting, Mississippi kites, cerulean warblers and other bird species and are important migratory songbird stopover sites.
Bird species associated with early-successional Floodplain Forests include: White-eyed Vireo, Yellow-breasted Chat, Common Yellowthroat, Indigo Bunting, Gray Catbird, Willow Flycatcher, Orchard Oriole, and Brown Thrasher.
Birds associated with mid-successional Floodplain Forests include: American Redstart, Northern Parula, and Willow Flycatcher.
Birds associated with late-successional Floodplain Forests include: Great Blue Heron (colonies especially in large sycamores and cottonwoods), Bald Eagle, Belted Kingfisher, Red-shouldered Hawk, Northern Parula, Louisiana Waterthrush, Wood Duck, Hooded Merganser, and Swainson’s Warbler (sites with giant cane or dense sapling/brambles in the understory).
Amphibian and reptile species associated with Floodplain Forest include: small-mouthed salamander, central newt, midland brown snake, gray tree frog, and southern leopard frog.
Other information
Forestry (NRCS 2002, 2014):
Management: Field collected site index values average 107 for eastern cottonwood. Soil fertility and available water capacity may be low to moderate. Timber management opportunities are fair to 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. Harvest methods that leave some mature trees to provide shade and soil protection may be desirable. Maintain adequate riparian buffer areas.
Limitations: Seasonal wetness from flooding; sandy profile. The sandy upper layer may hinder the use of wheeled equipment especially when the soil is saturated or very dry. Seedling mortality may occur because of lack of adequate soil moisture during dry periods.

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.
