MLRA notes
Major Land Resource Area (MLRA): 109X–Iowa and Missouri Heavy Till Plain
The Iowa and Missouri Heavy Till Plain is an area of rolling hills interspersed with interfluve divides and alluvial valleys. Elevation ranges from about 660 feet (200 meters) along the lower reaches of rivers, to about 980 feet (300 meters) on stable interfluve summits in southern Iowa. Relief is about 80 to 160 feet (25 to 50 meters) between major streams and adjacent interfluve summits. Most of the till plain drains south to the Missouri River via the Grand and Chariton River systems, but the northeastern portion drains southeast to the Mississippi River. Loess caps the pre-Illinoisan aged till on interfluves, whereas the till is exposed on side slopes. Mississippian aged limestone and Pennsylvanian aged sandstone and shale crop out on lower slopes in some areas.

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. As additional information is collected, analyzed and reviewed, this ESD will be refined and published as “Approved”.
Loamy Floodplain Prairies are common in smaller stream floodplains throughout the MLRA and adjacent areas. Soils are very deep and loamy, and subject to flooding. The reference plant community is prairie dominated by Indiangrass, big bluestem, little bluestem and sideoats grama, and a wide variety of prairie wildflowers.

Physiographic features
This site is on floodplains and floodplain steps, with slopes of 0 to 3 percent. The site generates some runoff to adjacent lower floodplain sites, and receives some runoff from stream terraces and uplands. This site is subject to flooding.
The following figure (adapted from Ferguson, 1999) shows the typical landscape position of this ecological site, and landscape relationships among the major ecological sites of the floodplain and stream terrace systems and adjacent uplands. This site is within the area labeled as “5” on the figure, and typically contains the active stream channel of the floodplain system. Wet Floodplain Prairie sites are often in adjacent, backswamp positions farther from the channel. Larger floodplain systems may contain stream terrace ecological sites, such as the Wet Terrace Prairie in the figure. Several sites occur in adjacent upland positions, particularly the Till and Footslope sites shown in the figure.

Climatic features
The Iowa and Missouri Heavy Till Plain MLRA 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.
This MLRA experiences small regional differences in climates that grade inconspicuously into each other. The basic gradient for most climatic characteristics is along a line from north to south. Both mean annual temperature and precipitation exhibit fairly minor gradients along this line. Mean January minimum temperature follows the north-to-south gradient. However, mean July maximum temperature shows hardly any geographic variation in the region. Mean July maximum temperatures have a range of only two to three degrees across the region.
Mean annual precipitation varies along the same gradient as temperature – lower annual precipitation in the north, higher in the south. Seasonality in precipitation is very pronounced due to strong continental influences. June precipitation, for example, averages four to five times greater than January precipitation. 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 influences ecological communities by limiting water supplies, especially at times of high temperatures and high evaporation rates. Drought indirectly affects ecological communities by increasing plant and animal susceptibility to the probability and severity of fire. Frequent fires encourage the development of grass/forb dominated communities and understories.
Superimposed upon the basic MLRA climatic patterns are local topographic influences that create topoclimatic, or microclimatic variations. 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. Slope orientation is an important topographic influence on climate. Summits and south-and-west-facing slopes are regularly warmer and drier, supporting more grass dominated communities than adjacent north- and-east-facing slopes that are cooler and moister that support more woody dominated communities. Finally, the cooler microclimate within a canopied forest is measurably different from the climate of a more open and warmer grassland or savanna area.

Influencing water features
This ecological site is in floodplains of perennial streams where prairie is extensive in the uplands. 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, and surface drainage systems have altered the hydrology and flooding dynamics in many places. Streambeds are typically incised into the surrounding floodplain by as much as 10 feet.
Soils in this ecological site typically have seasonal water tables below about two feet in the winter and spring, generally receding with the falling river levels in the early summer. The water table has a minimal effect on the vegetative community.
Soil features
These soils have no rooting restriction. They were formed under a mixture of woodland and prairie vegetation, with periodic depositional flood events. Organic matter content is high. Parent material is alluvium. They have silt loam surface horizons, and loamy substrata. They are well drained. Soil series associated with this site include Kennebec.

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 reference plant community is characterized as a tallgrass prairie unit dominated by big bluestem, Indiangrass, switchgrass, eastern gamagrass and a wide variety of prairie wildflowers while other species such as Culver’s root, Michigan lily, and Virginia bunchflower added to the mix of floodplain prairie species. Slightly higher areas within or at the edge of the floodplains supported widely scattered bur oak, pin oak, elm, shellbark hickory and willow.
These areas flooded periodically. In addition to the flooding, fire played a key role, likely occurring at least once every 3 years. Fire removed dead plant litter and provided room for a lush growth of prairie vegetation. Fire also controlled woody species. During fire free intervals woody species would have increased in abundance and spread out onto the prairie. Grazing by native large herbivores, such as bison, elk, and white-tailed deer, furthermore impacted these sites. Their activities altered the composition, fuel loads and structure of the vegetation, adding to the diversity of structure and composition.
Today, Loamy Floodplain Prairies are nearly extirpated from the region as the former floodplain prairies have been converted to intensive agriculture or non-native pasture. No reference quality remnants exist. While re-establishing prairie on agriculture sites is beneficial to wildlife, restoration to the reference state from agricultural land is a long term proposition, potentially expensive and with uncertain outcomes.
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
This State is native tall grass prairie dominated by big bluestem, eastern gama grass, and a wide variety of prairie wildflowers. In some cases, bur oak, pin oak, elm, American hazelnut, prairie willow and wild plum occurred in small groves or as scattered individuals across the prairie landscape. 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 bur oak, prairie willow, dogwoods and wild plum. When fire intervals shorten these woody species will decrease or be eliminated. This state is believed to be expatriated. All sites have been converted to cool season grassland and intensive agriculture cropland.

State 2
Woody Invaded Savanna
Degraded reference states that have experienced fire suppression for 20 or more years will transition to this state. With fire suppression, woody species such as bur oak, shellbark hickory and pin oak will begin to increase 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 increase. Transition from this state to cool season grasslands (State 3) or intensive cropland (State 4) was very common.

State 3
Cool Season Grassland
Conversion of other states to non-native cool season species such as tall fescue, white clover, and red clover has been common in this area. Occasionally, these pastures will have scattered bur oaks. Long term uncontrolled grazing and a lack of grassland management can cause significant soil erosion and compaction and increases in less productive species such as Kentucky bluegrass and weedy forbs such as ironweed. A return to the Reference State may be impossible and costly, requiring a very long term series of management options.

State 4
Cropland
This is the dominant State that exists currently with intensive cropping of corn, soybeans, and wheat occurring. Some conversion to cool season hayland occurs for a limited period of time before transitioning back to cropland. Limited acres are sometimes converted to native warm season grassland.

State 5
Native Warm Season Grassland
Conversion 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, money and management inputs will still be needed.
