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.

Classification relationships

Major Land Resource Area (MLRA): Wisconsin Central Sands (89)

USFS Subregions: Neillsville Sandstone Plateau (222Rb)

Small sections occur in the Lincoln Formation Till Plain - Mixed Hardwoods (212Qb) and Central Wisconsin Sand Plain (222Ra) subregions

Relationship to Established Framework and Classification Systems:
Habitat Types of N. & S. Wisconsin (Kotar, 2002 & 1996) and Wetland Forest Habitat Type Classification System for Northern Wisconsin (Kotar and Burger, 2017):
The sites of this ES keyed out to seven habitat types: Acer-Quercus/Viburnum, Geranium variant (AQVb-Gr); Acer saccharum-Tsuga/Athyrium-Onoclea (ATAtOn); Pinus/Vaccinium-Gaultheria (PVG); Pinus/Vaccinium-Rubus hispidus (PVRh); Pinus-Acer/Gaylussacia (PArGy); Ace rubrum-Fraxinus nigra/Rubus hispidus (ArFnRh). The latter two habitat types are wetland habitat types for Northern Wisconsin used in lieu of Southern Wisconsin wetland habitat types.

Biophysical Settings (Landfire, 2014): This ES is largely mapped as North-Central Interior Maple-Basswood Forest and Laurentian-Acadian Northern Hardwoods Forest.

WDNR Natural Communities (WDNR, 2015): This ES is most similar to the Northern Hardwood Swamp, Southern Hardwood Swamp, and White pine-Red maple Swamp.

Ecological site concept

The Wet Loamy Lowlands ecological site is widespread in the northern portion of MLRA 89, where loamy glacial till was deposited during the Wisconsin glaciation. These sites are characterized by very deep, somewhat poorly drained soils that formed in silty alluvium and loamy residuum weathered from interbedded sandstone and shale. Sites are subject to frequent, brief flooding during the growing season. Precipitation, runoff from adjacent uplands, and groundwater discharge are the primary sources of water. Soils range from very strongly acid to strongly acid. Some sites may be wetlands.

Historically, this Ecological Site was dominated by a variety of plant communities, apparently reflecting differences in historic fire regime. Prairie, Pine Barrens, Oak Barrens, Oak Savanna and mixed Pine - Oak forests were all represented (Finley, 1976). Following European settlement most of the area was cleared of forest vegetation and converted to farming, although scattered woodlots remained. Current woodlots typically consist of mixed oak, primarily white oak (Q. alba) and Red oak (Q. rubra), white pine (Pinus strobus) and red maple (Acer rubrum). Also common are mixed stands of trembling aspen (Populus tremuloides) and paper birch (Betula papyrifera). There also are considerable areas of planted red pine (P. resinosa).

Wet Loamy Lowlands differs from other sites primarily by its drainage and loamy textures. Other poorly drained sites have sandy or clayey textures. Loamy textures often have higher pH and available water capacity than sandy textures, which offer improved growing conditions for this site. Loamy and clayey sites are often similar in soil features, but clayey soils tend to hold more water and for longer periods than loamy soils. The poor drainage differentiates this site from other loamy sites.

Physiographic features

This site occurs in depressions and drainageways on pediments. Slopes range from 0 to 2 percent. Elevation ranges from 705 to 1,394 feet (215 to 425) meters above sea level.

Some sites are subject to occasional to frequent ponding throughout the year. The ponding duration is brief (2 to 7 days), with depth up to 12 inches (30 cm) above the soil surface. Some sites do not pond. These sites do not flood. The soils have a seasonally high water table at a depth of 0 to 4 inches (0 to 10 cm), but the water table may drop to 60 inches (50 cm) during dry conditions. Runoff is negligible to low.

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.

This site sometimes occurs on landscape depressions, where the local topography is expected to influence growing season length. In landscape depressions, the freeze-free and frost-free periods may be shorter than what is represented here.

The average annual precipitation for this ecological site is 33 inches. The average annual snowfall is 43 inches. The annual average maximum and minimum temperatures are 56°F and 33°F, respectively. This site is exclusive to the northern portion of the latitudinal gradient of this MLRA. The frost-free period of this site is 21 days shorter than the MLRA average (135 days, base 32°F).

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 evapotranspiration and groundwater recharge. These sites are wetlands.

Under the Cowardin System of Wetland Classification, or National Wetlands Inventory (NWI), the wetlands can be classified as:

1) Palustrine, forested, broad-leaved deciduous, saturated, or
2) Palustrine, forested, needle-leaved evergreen, saturated, or
3) Palustrine emergent, persistent, saturated

Under the Hydrogeomorphic Classification System (HGM), the wetlands can be classified as:

1) Depressional, forested/silty, or
2) Depressional, scrub-shrub/silty

Permeability of the soils range from rapid to very slow. Surface permeability is moderate or moderately slow but can be rapid to very slow in the subsurface based on textures with the varying parent materials. The hydrologic soil group of these sites is C/D.

Soil features

These sites are represented by the Veedum and Vesper soil series, both of which are classified as Humic Epiaquepts.

The Veedum series has bedrock within 26 inches (66 cm), but can range from 20 to 40 inches (50 to 100 cm). Vesper series does not have bedrock within 80 inches (200 cm). The silty mantle on these sites ranges from 10 to 28 inches (25 to 70 cm). In the Veedum series, the water table is perched on the bedrock. The NRCS writes that this soil series does not fit either definition of episaturation or endosaturation but expanded the definition of episaturation to include soils with a water table perched on top of bedrock, like Veedum. These soils are poorly drained and remain saturated for much of the growing season. They meet hydric soil requirements.

The surface of these sites is muck or silty loam. Subsurface horizons range from sand to clay loams based on parent material. Mineral soil has bedrock contact with interbedded sandstone and shale. Soil pH is very strongly acid to strongly acid in the profile with a range of 4.60 to 5.50. Surface fragments are absent. Subsurface fragments less than 3 inches can be present up to 7 percent by volume, and fragments greater than 3 inches can be present up to 6 percent. Sites are absent of carbonates within 80 inches (200 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, the shade-tolerant species, that typically dominate the more productive sites throughout Wisconsin.

In pre-European settlement time wild fire 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 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 oak (Q. rubra) is somewhat less shade-tolerant than the preceding species, and reproduces sporadically in larger canopy gaps and following a major stand disturbance.

Although red maple has not been identified by Finley (1976) as an important component of pre-settlement pine or oak forests, 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.

State 1
Reference State

In absence of stand-leveling disturbances the Reference State Community oscillates between two easily definable community phases, a mature, or late successional, community phase and a rejuvenated community phase.

Dominant plant species

eastern white pine (Pinus strobus), tree
white oak (Quercus alba), tree
red maple (Acer rubrum), tree
serviceberry (Amelanchier), shrub
western brackenfern (Pteridium aquilinum), other herbaceous

Community 1.1
Advanced Succession Phase

A mature forest community contains a super-canopy, or a scattering, of large white pine trees. In pre-European settlement time such trees would have been anywhere from 80 to more than 300 years old (Sterns, 1950). Common associates have been red pine (P. resinosa), red oak (Q. rubra) and white oak (Q. alba). However, only white pine and white oak are moderately shade-tolerant and able to reproduce in small canopy openings and remain as permanent members of mature community in absence of moderate to severe disturbance. Red maple (Acer rubrum) had not been an important species in pre-settlement forests but is today the most successful reproducing tree species in forest communities on this Ecological Site.

Dominant plant species

eastern white pine (Pinus strobus), tree
white oak (Quercus alba), tree
red maple (Acer rubrum), tree
serviceberry (Amelanchier), shrub
western brackenfern (Pteridium aquilinum), other herbaceous

Community 1.2
Rejuvinated Phase

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.

Dominant plant species

eastern white pine (Pinus strobus), tree
white oak (Quercus alba), tree
red maple (Acer rubrum), tree
serviceberry (Amelanchier), shrub
western brackenfern (Pteridium aquilinum), 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.

Context dependence. Disturbance-free period 30+ years

State 2
Post Logging State

Post-logging state may consist of considerable diversity of pioneer and mid-successional community phases. Here we are describing four, most commonly found under current conditions.

Dominant plant species

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

Community 2.1
Jack Pine Phase

Jack pine and red pine have historically been almost entirely dependent on fire for regeneration. Jack pine is a predominantly a northern species and in southern part of Wisconsin seldom approaches its growth potential. Everywhere it occurs it is a pronounce pioneer, highly light demanding and resistant to drought and frost. It has low requirements for soil organic matter and nutrients. It is a prolific producer of seed and it often colonizes burnt over areas. Forest fires speed natural regeneration by opening the cones. However, today, jack pine is regenerated mostly by planting. Without disturbance jack pine does not regenerate and is readily succeeded by various species, even those of only moderate shade tolerance, such as white pine and red oak. Historically, red pine has often occurred in mixtures with jack pine. In terms of light, soil moisture and nutrient requirements it is intermediate between jack and white pines. In contrast to jack pine, natural red pine regeneration is often found in moderately dense pure or mixed pine stands, although not to the same extent as is white pine. Under current ecological and economic conditions red pine is regenerated almost entirely by planting.

Dominant plant species

jack pine (Pinus banksiana), tree
red pine (Pinus resinosa), tree

Community 2.2
Aspen-Birch Phase

Although a ubiquitous species, quaking aspen (Populus tremuloides) is far more characteristic of northern rather than southern forest regions. Its most notable ecological characteristic is the ability to rapidly invade cut-over and burned-over areas. However, its perpetuation depends entirely on recurrence of disturbance. Because of its extreme intolerance to shade, it is readily replaced by many tree species in the absence of disturbance. Once in place, aspen reproduces entirely by sprouting from extensive, superficial root systems (root suckering). Most aspen stands on this Ecological Site resulted from sprouting following clear cutting of mixed stands of pine and/or oak, in which some aspen trees were still present. Paper birch (Betula papyrifera) is often a member of aspen stands. It shares aspen’s intolerance of shade and also produces small, winged seeds that readily disperse by wind. It does not sucker from root sprouts, but it readily sprouts from stumps upon clear cutting. It also has greater ability than does aspen of reproducing from seed under favorable seedbed conditions and in presence of large canopy openings. However in absence of disturbance it also succeeds to other species.

Dominant plant species

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

Community 2.3
Pin Oak-Black Oak-White Oak Phase

On this Ecological Site these three oak species occur in mixtures dominated by any of them. In some stands there also occur red oak, bur oak (Q. macrocarpa) or shagbark hickory (Carya ovvata). Community composition and structure is a function of composition of the preceding, cut-over, or burned-over community and time since the disturbance. Time since disturbance is an important factor because of significant differences in sprouting abilities and success of regeneration from seed, among the participating species. Pin and black oak typically exist in current stands as multy-stem clusters resulting from stump sprouting, while white oak often reproduces from seed and gradually gains canopy dominance because of its greater shade tolerance than that of other oak species.

Dominant plant species

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

Community 2.4
Mid-Succession Phase

This community phase is considered a mid-successional community between the pioneering communities 2.1, 2.2, 2.3 and the Reference State. The community is characterized by canopy dominance of any of the early - succession species (i.e.: oaks, aspen - birch, jack pine) and strong presence in the understory of white pine and/or red maple seedlings and saplings.

Dominant plant species

white oak (Quercus alba), tree
eastern white pine (Pinus strobus), tree
red maple (Acer rubrum), tree

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.
