MLRA notes

Major Land Resource Area (MLRA): 089X–Wisconsin Central Sands

The Wisconsin Central Sands (MLRA 89) corresponds closely to Central Sand Plains Ecological Landscape published by the Wisconsin Department of Natural Resources (WDNR, 2015). Much of the following brief overview of this MLRA is borrowed from that publication.

The Wisconsin Central Sands MLRA is entirely in Wisconsin. The total land area is 2,187,100 acres (3,420 square miles, 8858 square kilometers). It is bordered to the east by Johnstown-Hancock end moraines, which were pushed to their extent by the west side of the Green Bay Lobe (Clayton & Attig, 1999). It is bordered to the southwest by highly eroded, unglaciated valleys and ridges. The dominant feature of this MLRA is the remarkably flat, sandy plain, composed of lacustrine deposits and outwash sand, that was once the main basin of Glacial Lake Wisconsin. It also features extensive pine and oak barrens and wetland complexes.

Glacial Lake Wisconsin was fed primarily by glacial meltwater from the north and east. The lake deposited silt overlain by tens of meters of sand (Clayton & Attig, 1989). The silty layers are closer to the surface in some areas, where they impede drainage and contribute to the formation of extensive wetland complexes. It is believed that Glacial Lake Wisconsin drained within several days after a breach in the ice dam that supported it. The catastrophic flood that followed flowed to the south and carved the scattered buttes and mesas protruding from the sandy plain in the southern portion of this MLRA. Before vegetation established after glacial recession, strong winds formed aeolian sand dunes that now support xeric pine and oak stands within the Wisconsin Central Sands.

The surface of the northwestern portion is mostly undulating. The sandy surface sediment was mostly deposited by meltwater during the Wisconsin glaciation. Gentle hills are a result of underlying bedrock topography. Valleys and floodplains are formed by stream action. The underlying bedrock controls the water table elevation and contributes to the formation of numerous wetlands.

Historically, the Wisconsin Central Sands were dominated by large wetland complexes, sand prairies, and oak forests, savannas, and barrens. Some pine and hemlock forests were found in the northwest portion. The Wisconsin Central Sands was subject to frequent fires, leading to today’s need for prescribed burns to maintain the area.

WDNR Natural Communities (WDNR, 2015): This ES is most similar to the Central Sands Pine-Oak Forest, Hardwood Forest, and Northern Mesic Forest communities.

Ecological site concept

The Moist Clayey Uplands ecological site is an uncommon site but exists in the southern portion of MLRA 89 in depressions and drainageways on the glacial lake basin and lake terraces, often (but not exclusively) within five miles of the Lemonweir River. These sites are characterized by very deep, somewhat poorly drained soils formed in silty or sandy alluvium over clayey lacustrine deposits. Precipitation, runoff from adjacent uplands, and groundwater discharge are the primary sources of water. Soils can range from neutral to moderately alkaline.

Although these soils are classified as Somewhat Poorly Drained the vegetation does not reflect this condition. It appears that poorly drained condition occurs more as micro-sites rather than the general character of the site. The dominant tree species on four representative sites were red oak (Quercus rubra), red maple (Acer rubrum) and white pine (Pinus strobus). Other species were white oak (Q. alba), northern pin oak (Q elipsoidalis) and trembling aspen (Populus tremuloides). Common understory flora included sedges (Carex spp.), blueberries (Vaccinium spp.), starflower (Trientalis boreralis), wild lily of-the-valley (Maianthemum canadense). Wetter micro sites were characterized by some of the following: Winterberry (Ilex verticillata), tag alder (Alnus crispa), swamp dewberry (Rubus hispidus) or cinnamon fern (Osmunda cinnamomea).

Moist Clayey Uplands differs from other sites by its drainage and clayey textures. Other poorly drained sites are sandy or loamy. Clayey soils often have higher pH and available water capacity than sandy and loamy textures. The somewhat poor drainage differentiates this site from other clayey sites.

Physiographic features

These sites formed in depressions and drainageways on outwash plains, lake terraces, and glacial lake basins. Slopes range from 0 to 3 percent. Elevation ranges from 705 to 1,394 feet (215 to 425) meters above sea level. These sites are not subject to ponding or flooding. Sites have a seasonally high water table at a depth of 6 to 24 inches (15 to 61 cm). The water table can drop to 60 inches (150 cm) during dry conditions. Surface runoff ranges from low to high.

Climatic features

The continental climate of the Wisconsin Central Sands is typical of the southern half of the state – cold winters and warm summers. Precipitation is well-distributed throughout the year with a slight peak in the summer months. Snowfall covers the ground from late fall to early spring. The soil moisture regime of MLRA 89 is udic (humid climate). The soil temperature regime is mostly frigid, with a small portion of mesic in the southern tip. Neither precipitation nor temperature vary greatly across this MLRA. More so than latitude, local topography seems to be an important predictor of growing season length, with fewer growing degree days in lower-lying areas.

The average annual precipitation for this ecological site is 34 inches. The average annual snowfall is 41 inches. The annual average maximum and minimum temperatures are 56°F and 34°F, respectively.

Influencing water features

Water is received through precipitation, runoff from adjacent uplands, groundwater discharge, and, rarely, stream inflow. Water levels are greatly influenced by precipitation rates and runoff from upland sites. Water leaves the site primarily through runoff, evapotranspiration, and groundwater recharge. Permeability of these sites is impermeable. Hydrologic group is B or D.

Soil features

These sites are represented by the Neenah and Wyeville soil series, classified as Aquollic Hapludalfs and Aquic Arenic Hapludalfs, respectively. These soils formed in sandy and loamy alluvium over clayey lacustrine deposits. Sites are poorly drained. They do not meet hydric soil requirements. The surface of these sites is loamy sand or silt loam. Subsurface textures are sand, silt loam, and silty clay. Soil pH ranges from slightly acid to moderately alkaline with values of 6.2 to 8.1. Surface and subsurface fragments are absent. Carbonates can be present up to 18 percent beginning at 27 inches (69 cm).

Ecological dynamics

Perhaps the most important ecological characteristic of this Ecological Site, in terms of its influence on forest community dynamics, is its lack of capacity to support the high to moderate soil moisture and nutrient requiring species such as sugar maple, basswood and white ash. These are the shade-tolerant species that typically dominate the more productive sites throughout Wisconsin.

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. White pine (Pinus strobus) is best adapted for long-term success on this Ecological Site. Although vulnerable to damage or elimination by fire in early life it eventually develops thick fire-resistant bark which helps to extend its longevity, in some cases for up to four centuries or more. These survival properties assure the species’ relatively continuous seed source in the region as a whole. White pine is also moderately shade-tolerant in early life which means that it can become established in some pioneer communities, such as aspen – white birch stands, or in poorly stocked oak and red maple dominated communities. Red pine had in the past been a common associate of white pine stands. It shares some of the fire-resisting properties of white pine, but it lacks shade-tolerance and does not become established in the understory. For this reason, it has not maintained its presence in current stands and its seed source has been greatly reduced throughout its natural range following the unset of fire suppression. Several species of oak are common members of forest communities on this ecological site. Northern pin oak (Q. ellipsoidalis) and, to a lesser degree, black oak (Q. velutina), are intolerant of shade and do not reproduce from seed under existing canopies. However, following fire or clear cutting they respond by sprouting from stumps. In the absence of disturbance they are replaced, through succession, by more shade-tolerant white pine, red maple (Acer rubrum), or white oak (Q. alba).

Red maple has not been identified by Finley (1976) as an important component of pre-settlement pine or oak forests, but it is a prominent member in current stands. Absence of fire since the original logging era is probably the main reason. Red maple is extremely sensitive to fire damage, but is a prolific and early seed producer. Stems of 2-4 inches in diameter can produce large amounts of seed (USDA For. Serv. 1990). It is sufficiently shade-tolerant to become established in the understories of most communities on sandy soils. On this Ecological Site it behaves similarly to white pine, but because of its much smaller size at maturity, it does not compete with white pine in the upper canopy.

4.1. Agricultural Community

State 1
Reference State

The reference state plant community is categorized as dry, nutrient poor forest, composed of any mixture of pines including Jack pine (Pinus banksiana), Red pine (P. resinosa), and white pine, (P. strobus). Several species of oak may be on site including northern pin oak (Quercus ellipsoidalis), black oak (Q. velutina), and white oak (Q. alba). Red maple (Acer rubrum) is a common subcanopy tree. All of these species, except for white pine and red maple, depend on disturbance, especially fire, to maintain their presence in the community. In the absence of stand-replacing fires two common community phases can be recognized: mature, or advanced succession community phase, and rejuvenated community phase.

Dominant plant species

pine (Pinus), tree
oak (Quercus), tree

Community 1.1
Advanced Succession Phase

Scattered super-canopy White pines with white oak and red maple as second canopy. Scattered mature red oak and/or red pine are often present. Understory is dominated by hazelnut (Corylus spp.), black cherry (Prunus serotina), bracken fern (Pteridium aquilinum) and wild lily of the valley (Maianthemum canadense). Seedlings and saplings of canopy species, other than red maple, are scarce or absent.

Dominant plant species

eastern white pine (Pinus strobus), tree
white oak (Quercus alba), tree
red maple (Acer rubrum), tree
hazelnut (Corylus), shrub
black cherry (Prunus serotina), shrub
brackenfern (Pteridium), other herbaceous
European lily of the valley (Convallaria majalis), other herbaceous

Community 1.2
Rejuvenated Phase

Openings in the canopy resulting from disturbances in pathway 1.1A create opportunities for potential regeneration of all canopy species. The species composition and age structure is modified by the loss of some mature individuals and addition of young cohorts of some species currently making up the tree community. Because of differences in reproduction biology and environmental requirements for progeny establishment among the species, the new composition is not entirely predictable, but rather, it depends on specific conditions prevailing during and after each disturbance event. Understory species composition is similar to that in Phase 1.1, but relative abundance of represented species varies.

Dominant plant species

eastern white pine (Pinus strobus), tree
white oak (Quercus alba), tree
red maple (Acer rubrum), tree
hazelnut (Corylus), shrub
black cherry (Prunus serotina), shrub
brackenfern (Pteridium), other herbaceous
European lily of the valley (Convallaria majalis), other herbaceous

Pathway 1.1A
Community 1.1 to 1.2

Periodic light to moderate intensity disturbances e.g., ice storms and blow downs create openings in the canopy, and low intensity fires reduce potential competing vegetation in the understory.

Pathway 1.2A
Community 1.2 to 1.1

Time, addition of regeneration of at least some species comprising the advanced succession community phase. This process maintains the reference community phase in the absence of stand replacing fires.

State 2
Post-Logging State

Following original logging around the turn of the 20th century, most logged over areas were followed by fire, often repeatedly, for decades. There was almost no replanting until the 1930’s and 1940’s and new forests, where land was not converted to farming, regenerated naturally, with varying degree of stocking and with varying species mixtures. Eventually planting became the principal method of reforestation with red pine as the most common species of choice. The most common naturally regenerated forest cove types were Jack pine, some times in mixtures with red pine, aspen-paper birch and mixed oak.

Dominant plant species

pine (Pinus), tree
oak (Quercus), tree
quaking aspen (Populus tremuloides), tree
red maple (Acer rubrum), tree
hazelnut (Corylus), shrub
western brackenfern (Pteridium aquilinum), other herbaceous

Community 2.1
Jack Pine Phase

Where seed sources were not destroyed by fire Jack pine readily colonized newly opened lands, some times accompanied by admixture of red pine. White pine was not often a member of these communities because the seed source was absent and any remaining seedlings and saplings were eliminated by post-logging fires.

Dominant plant species

jack pine (Pinus banksiana), tree

Community 2.2
Aspen-Birch Phase

In some logged over stands there were scattered old specimens of aspen, either quaking or trembling, and these became sources for sprouting new clones. Under favorable conditions white birch of seed origin became a successful associate.

Dominant plant species

quaking aspen (Populus tremuloides), tree
paper birch (Betula papyrifera), tree

Community 2.3
Pin Oak-Black Oak-White Oak

These three oak species are commonly members of mid-successional forest communities on this site type. Following logging they readily sprout from stumps or from root crowns of saplings that were destroyed in logging operations. Because of rapid growth of sprouts these species easily outcompete pioneer species that propagate through seed, such as paper birch, or any of the pines. In absence of disturbance pin and black oaks slowly drop out of the community due to lack of shade tolerance, but white oak increases its presence frequency and dominance because of its considerably greater shade tolerance.

Dominant plant species

pin oak (Quercus palustris), tree
black oak (Quercus velutina), tree
white oak (Quercus alba), tree

Community 2.4
Mixed Species Phase

Pure, or mixed stands of jack pine, red pine, oaks, white pine and red maple. Species composition and age structure of any given community depends on which early successional stage it is representing. The common denominator is the presence of shade tolerant white pine and red maple, which with time reach community dominance.

Dominant plant species

jack pine (Pinus banksiana), tree
quaking aspen (Populus tremuloides), tree
white oak (Quercus alba), tree
eastern white pine (Pinus strobus), tree
red maple (Acer rubrum), tree
hazelnut (Corylus), shrub
brackenfern (Pteridium), other herbaceous
