MLRA notes

Major Land Resource Area (MLRA): 105X–Upper Mississippi River Bedrock Controlled Uplands and Valleys

The Northern Mississippi Valley Loess Hills area corresponds closely to the Western Coulees and Ridges and Southwest Savanna Ecological Landscapes. Some of the following brief overview is borrowed from the Wisconsin Department of Natural Resources Ecological Landscape publication (2015).

Fifty-two percent of the Upper Mississippi River Bedrock Controlled Uplands and Valleys MLRA is in Wisconsin; Iowa, Minnesota, and Illinois contain the rest. This region is the only area in Wisconsin that has not been covered by glaciers within the past 2.4 million years. The Wisconsin portion of this MLRA is approximately 7.4 million acres (11,600 square miles). The landscape is characterized by dissected topography with deeply-incised, steep-walled valleys between bedrock controlled ridges.

Though it’s called the “Driftless Region”, some glacial drift is found in the major river valleys of this region in the form of outwash, deposited by proglacial streams of glacial meltwater. Wisconsin’s most recent glaciations also impacted the sediment of the area through the deposition of loess. After the glacier receded and before vegetation established, the bare surfaces of the glaciated areas were highly susceptible to wind erosion. As a result, a veneer of loess (wind-blown silt) was deposited over the entire region. The thickest deposits—nearly five meters—are on ridges near the Mississippi River and gradually thin moving eastward. The loess caps in Dane and Green counties are generally 0.5-1.5 meters deep. Much of the loess has eroded downslope and collected in floodplains.

Bedrock is shallow throughout this MLRA and is a major influence on topography and hydrology. Most of the MLRA has bedrock within two meters, except in the deep river valleys that are filled with outwash and alluvium materials. Sandstone is the dominant bedrock type in MLRA 105, but the southernmost portion is dominated by dolomite. Military Ridge is an escarpment that straddles the boundary between sandstone and dolomite bedrock. The sandstone north of the ridge is weaker than the erosion-resistant dolomite south of the ridge. The sandstone is deeply cut and dissected into steep slopes and valleys. The dolomite-controlled ridges tend to be less dissected and broader with more gentle, south sloping topography. Geomorphic and fluvial processes formed these landscapes by way of sheet wash, soil creep, and flowage. These processes eroded the hillslopes, cut into bedrock, and transported the debris to streams, forming floodplains and terraces.

Underfit streams are common in MLRA 105, especially in the southern portion. These streams currently occupy large river valleys—especially those of the Black, Chippewa, Mississippi, and Wisconsin Rivers—that were carved by proglacial meltwater streams carrying much larger quantities of water than what’s present today. As the climate dried, waterflow decreased and the valleys filled with alluvial sediment. Narrow meanders were formed by the shrinking streams and are often dissimilar to the meanders of the larger valleys they occupy. Fluvial landforms – including terraces, oxbow lakes, sandbars, eroding bluffs, and large floodplain complexes – are found within these large valleys and are subject to varying flooding frequencies, intensities, and durations.
Karst topography formed in this region from dissolution of carbonate bedrock by surface and groundwater. Dolomite and limestone are more easily affected by dissolution, but karst topography also formed in sandstone. Erosion by water (stream meanders, rain/runoff, and groundwater), wind, and frost weaken joints and bedding planes that can cause collapse. In addition, sandstone materials collapse into cavities in underlying dolomite or limestone.

Historically, MLRA 105 was dominated by oak forests and oak openings making up more than 50% of the area. Prairies were significant and covered 32% of the area south of Military Ridge. Maple-basswood forests covered 19% of the are north of Military Ridge. Dominant tree species were white oak (Quercus alba), bur oak (Quercus macrocarpa), black oak (Quercus velutina), and sugar maple (Acer saccharum).

Ecological site concept

The Moist Sandy Lowland ecological site accounts for approximately 18,000 acres on MLRA 105, or about 0.26% of total land area. It is one of the least extensive sites in the MLRA. It can be found on sandy valley trains and sandstone hills in lower landscape positions. About 70% of the acreage of this site is found north of the Black River.

This site is characterized by very deep, somewhat poorly drained soils formed in sandy materials. Most sites in the east-central portion of this MLRA (mainly Monroe and Jackson counties) formed in siliceous sandy alluvium deposits weathered and reworked from silica-cemented sandstone. Other sites formed in sandy outwash deposits. Sites are generally not inundated by water during the growing season.

Climatic features

The climate of the Upper Mississippi River Bedrock Controlled Uplands and Valleys MLRA is typical of southern Wisconsin, with warmer winters, warmer summers, and higher precipitation rates than MLRA in northern Wisconsin. The MLRA stretches over about 2.9 degrees of latitude, or nearly 200 miles, from its northern tip in Barron county to its southern Wisconsin extent on the border of Illinois. This results in considerable variation in climate throughout the MLRA. The growing season ranges from 117 to 181 growing degree days, with longer growing seasons in the southern portion.

The average annual precipitation for this ecological site is 33 inches. The average annual snowfall is 41 inches. The annual average maximum and minimum temperatures are 55°F and 34°F, respectively.

Influencing water features

Water is received through precipitation, runoff from adjacent uplands, and groundwater discharge. Water levels are greatly influenced by precipitation rates and runoff from upland sites. Water is lost from the site primarily through runoff, evapotranspiration, and groundwater recharge.

Permeability of the soil is very slow to rapid. The hydrological groups for this site are A and A/D.

Soil features

This site is represented by the Farrington, Majik, Meehan, Morocco, and Watseka soil series, and by a variant of the Warma soil series. Aquic Quartzipsamments make up 39% of the acreage of this site. Aquic Hapludolls make up 30%, Aquic Udipsamments make up 22%, and Ultic Epiaquods make up 9%.

These soils formed in sandy outwash or sandy alluvium. The sandy deposits are often derived of weathered sandstone and may contain over 95% silica (siliceous sand).
These soils sometimes have loamy or organic surfaces. They typically do not have bedrock contact within 6 feet (2 meters). They are somewhat poorly drained. They do not meet hydric soil requirements. Subsurface fragments smaller than 3inches in diameter (gravel) may occupy up to 21% volume in some sites, especially those sites in the sandy outwash plains along major rivers within this MLRA. Soils are very strongly acid to neutral. They typically lack secondary carbonates.

Ecological dynamics

In pre-European settlement time wildfire was the main controlling factor of forest community dynamics. Following a severe, stand-replacing fire, any of the species present on the landscape could become established, depending on seed source availability and specific conditions of post-fire seedbed. The newly established young stands of any species were easily eliminated by recurring fires, but differences in fire-resisting properties among the species began to play a role in any species’ survival success. Many pine and oak species were dominant in the region because of their fire-resistant properties and successful regeneration post-fire. With clear cutting and continued fire suppression, many of these species adapted to fire and intolerant of shade, are replaced by other species. Species such as white pine and red oak are still common on the landscape based on their tolerance to some shade; these species to establish under a canopy, and in time, may become a component of the canopy. Red maple is sensitive to fire, but in its absence, it has the ability to dominate sites based on its shade tolerance and prolific seed production. Many sites within this ES may lack White pine as the seed source is still only slowly returning after most of the White pine was logged. In situations where White pine seed source is lacking, Red maple and various oaks will dominate.

State 1
Reference State

Reference state is a forest community dominated by White pine (Pinus strobus) and red maple (Acer rubrum), and various oaks (Quercus spp.). Depending on history of disturbance, two community phases can be distinguished largely by differences in dominance of tree species, shrub layer presence and coverage, and community age structure.

Community 1.1
Advanced Succession Community

In the absence of major disturbance—particularly fire—these sites are dominated by a canopy of White pine and Red maple. Red oak (Quercus rubra) may be present, but has low coverage and is only able to regenerate in gaps Pin oak (Quercus ellipsoidalis) is also likely. The shrub layer is not well developed but likely contains blueberries (Vaccinium, spp.) and Rubus spp. The ground layer is dominated by Canada mayflower (Maianthemum canadense).

Dominant plant species

eastern white pine (Pinus strobus), tree
red maple (Acer rubrum), tree
oak (Quercus), tree
blueberry (Vaccinium), shrub
Canada mayflower (Maianthemum canadense), other herbaceous

Community 1.2
Rejuvenated Community

The canopy of the rejuvenated community is still dominated by original species, but the understory now also includes a well-established younger cohort and perhaps a few additional seedlings and saplings of less shade tolerant species. The shrub layer is more developed in this phase and likely contains Black cherry and chokecherry.

Dominant plant species

eastern white pine (Pinus strobus), tree
red maple (Acer rubrum), tree
oak (Quercus), tree
black cherry (Prunus serotina), shrub
chokecherry (Prunus virginiana), shrub
Canada mayflower (Maianthemum canadense), other herbaceous

Pathway 1.1A
Community 1.1 to 1.2

Light intensity fires, crown breakage from ice and snow and small scale blow-downs create canopy openings, releasing advance regeneration and stimulating new seedling establishment. Some additional less shade tolerant species such as red oak may be able to enter the community.

Pathway 1.2A
Community 1.2 to 1.1

A long period without major canopy disturbance allows gradual replacement of oldest canopy trees by younger cohorts. Small scale disturbances may still occur periodically, but once second or third canopies are established there is minimal new regeneration taking place and the forest gradually returns to mature state.

State 2
Deciduous Forest State

Post disturbance pioneer community of aspen and paper birch with mixtures of other species from available seed sources.

Community 2.1
Deciduous Forest Phase

Pure, or mixed, aspen – paper birch community replaces the reference state community. If seed source is present, red maple and young cohorts of oaks readily become members of this community.

Dominant plant species

quaking aspen (Populus tremuloides), tree
European white birch (Betula pendula), tree
red maple (Acer rubrum), tree
oak (Quercus), tree
beaked hazelnut (Corylus cornuta), shrub
black cherry (Prunus serotina), shrub
Canada mayflower (Maianthemum canadense), other herbaceous

State 3
Agricultural State

Indefinite period of applying agricultural practices. Crops likely include alfalfa, corn, soybeans, and hay or pasture. It is possible that some areas are or have been in ginseng production as well.

Community 3.1
Planted Crops

Indefinite period of applying agricultural practices. Crops likely include alfalfa, corn, soybeans, and hay or pasture.

Transition T1A
State 1 to 2

State 1 to 3

Removal of forest cover, tilling and application of other agricultural techniques to grow agricultural crops.

Restoration pathway R2A
State 2 to 1

Deciduous forest community is slowly invaded by conifers.

Transition T2A
State 2 to 3

Removal of forest cover, tilling and application of other agricultural techniques to grow agricultural crops.
