MLRA notes

Major Land Resource Area (MLRA): 094B–Michigan Eastern Upper Peninsula Sandy Glacial Deposits

he Michigan Eastern Upper Peninsula MLRA (94B) corresponds closely with the Northwestern Sands Ecological Landscape. Some of the following brief overview is borrowed from the Wisconsin Department of Natural Resources ecological landscape publication (2015).

The Michigan Eastern Upper Peninsula MLRA is in northeast Wisconsin on the border of the Upper Peninsula of Michigan, with a very small portion on the Lake Michigan coast disjoined from the rest of the MLRA. The Wisconsin portion of the MLRA is a bit shy of 1.1 million acres (1,668 square miles). This region, which was covered entirely by the Green Bay Lobe in Wisconsin’s most recent glaciation, has a unique glacial landscape defined by intermingled loamy moraines and sandy heads-of-outwash. Extensive pitted outwash plains dominate the region, with significant glaciolacustrine sediments in the southeast portion of this region.

A prominent landform in this MLRA is the hummocky ridges of intermingled loamy moraines and sandy heads-of-outwash that protrude from extensive pitted outwash plains. These north-south trending, loamy morainal ridges were deposited as the Green Bay Lobe was stagnant—the rate of melting was relatively equal to the rate of advancement. This stagnation allowed the deposition of a ridge of sandy loam materials. Supraglacial till was deposited unevenly, and buried ice blocks melted and collapsed the surface to form hummocky topography on the moraines. The heads-of-outwash formed while the ice was melting and thinning rapidly. Large amounts of sand and gravel outwash materials, and some till and loamy debris-flow sediment, were deposited on top of the thin edge of ice. They, too, have hummocky topography resulting from the collapse of buried ice. The topographically similar appearances of the moraines and heads-of-outwash make them difficult to distinguish superficially, but they are formed in different-textured materials and the vegetation divergence is often evident. These moraines and heads-of-outwash mark the western extent of the Green Bay Lobe and are sometimes referred to as the Athelstane Moraines.

As the Green Bay Lobe receded, meltwaters carried sand and gravel outwash sediments to lower-lying areas. The outwash buried broken ice that melted, collapsed the surface, and created extensive pitted outwash plains that occur between the high elevation moraines and heads-of-outwash. More than 50% of this land region is covered in outwash sediments, and most of the outwash is pitted or collapsed.

The southeast portions of this MLRA are dominated by glacial lake sediments. Glacial Lake Oshkosh covered a portion of this MLRA when it was at its largest extent (1.4 million acres). The lake deposited silts and clays along the southeast portion of the inland section of this MLRA. Beach terraces, ridges, and dunes were also formed by the lake. In the Lake Michigan coastal section of this MLRA, Glacial Lake Nipissing deposited a level lake plain full of sandy lacustrine material that overlies dolomite and limestone bedrock. Glacial Lake Nipissing was a postglacial lake that occurred in the Lake Michigan Basin as the Lake Michigan Lobe was receding. Wetlands are abundant in this area of the MLRA. In the north section, Glacial Lake Dunbar formed when ice dams impounded glacial meltwater between the Athelstane Moraine and the Inner Athelstane Moraine. This glacial lake deposited small areas of level sandy lacustrine materials.

The northeast section of this MLRA is a till plain that formed in later advances of the Green Bay Lobe. Some pitted outwash is present, but the till plain is much more exposed here than elsewhere in the MLRA. The till deposited throughout 94B is primarily sandy, dolomitic till. The dolomite was scraped off the Niagara Escarpment as the Green Bay Lobe moved across it. In some areas, the carbonates are deeply leached.

Historically, this MLRA was dominated by a mixture of northern hardwood forests, Jack pine-scrub oak barrens, and forested coniferous wetlands at 30%, 29%, and 20%, respectively. White pine (Pinus strobus) and red pine (Pinus resinosa) were dominant tree species and covered an estimated 15% of the area. Northern hardwood forests were dominated by eastern white pine, eastern hemlock (Tsuga canadensis), and American beech (Fagus grandifolia). The Jack pine-scrub oak barrens were dominant in the sandy portions of this MLRA. Forested coniferous wetlands were occupied by norther white-cedar (Thuja occidentalis), black spruce (Picea mariana), and tamarack (Larix laricina).

Ecological site concept

The Wet Loamy Lowland ecological site accounts for approximately 4,000 acres in MLRA 94B, or about 0.4% of total land area. It is the least extensive site in MLRA 94B. It is found in depressions and drainageways primarily on moraines, especially the Mountain, Athelstane, and Homestead Moraines along the western border of MLRA 94B. It can also be found in lake plains and loamy outwash plains.

This site is characterized by very deep, very poorly to poorly drained, loamy soils. Sites are subject to ponding in the spring and fall. Soils remain saturated for long periods during the growing season and meet hydric soil requirements. Precipitation, runoff from adjacent uplands, groundwater discharge, and stream inflow are the primary sources of water.

Physiographic features

This site is found on depressions and drainageway on moraines, lake plains, and outwash plains. It is most common on the morainal ridges found along the western border of this MLRA. Slopes range from 0 to 2 percent.

This site is subject to occasional to frequent ponding. Ponding duration may be brief (2 to 7 days) to very long (greater than 30 days). The soils have evidence of a seasonally-high water table at the surface, though the water table may drop in dry conditions. Some sites, especially those that formed in clayey glacial lake deposits, have a perched water table (episaturation). Runoff potential is low.

Soil features

The soils of this site are represented by the Bruce, Ensley, Minocqua, and Pickford soil series. Endoaquepts make up 43% of the acreage of this site. Epiaquents make up 25% The remaining acreage is made up of Epiaquepts and Haplaquepts.

These soils form in loamy to clayey deposits of till and lacustrine materials, sometimes underlain by sandy and gravelly outwash deposits. Sites lack bedrock contact within two meters. Soils are very poorly to poorly drained and meet hydric soil requirements.

The surfaces of these soils may be sand to silty clay loam, sometimes mucky. The subsurface may be sand to silty clay. Small fragments (gravels) may occupy up to 27 percent of the subsurface. Soils are strongly acid to moderately alkaline. Secondary carbonates may occupy up to 20 percent volume.

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.

3.1. Agricultural Phase

State 1
Reference State

Reference state is a forest community dominated by red maple (Acer rubrum) with groups of balsam fir (Abies balsamea). Depending on history of disturbance, two community phases can be distinguished largely by differences in dominance of tree species and community age structure.

Community 1.1
Advanced Success Community Phase

In the absence of major disturbance—particularly fire—these sites are dominated by a canopy of red maple and balsam fir. Sites may have a super-canopy of large white pine that might be able to maintain itself in few numbers through regeneration in gaps. White pine (Pinus strobus) has a moderate shade tolerance and grow to be much larger than red maple and balsam fir at maturity and typically live longer. The shrub layer is not well developed and dominated by red maple saplings and beaked hazelnut (Corylus cornuta). The ground layer is highly variable but often contains interrupted fern (Osmunda claytoniana) and various wet herbaceous plants (horsetail, goldthread, miterworts, black ash seedlings).

Dominant plant species

red maple (Acer rubrum), tree
balsam fir (Abies balsamea), tree
gray alder (Alnus incana), shrub
beaked hazelnut (Corylus cornuta), shrub
interrupted fern (Osmunda claytoniana), other herbaceous

Community 1.2
Rejuvenated Community Phase

Figure 8. Photo courtesy of UWSP taken on 6/27/2020 in Oconto County, WI.

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. It is unable to compete with red maple and balsam fir to maintain a position in the canopy in advanced succession.

Dominant plant species

red maple (Acer rubrum), tree
balsam fir (Abies balsamea), tree
beaked hazelnut (Corylus cornuta), shrub
gray alder (Alnus incana), shrub

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

Figure 9. Photo courtesy of UWSP taken on 7/1/2020 in Marinette County, WI.

Pure, or mixed, aspen – paper birch community replaces the reference state community. If seed source is present, red maple and young cohorts of balsam fir readily becomes member of this community.

Community 2.1
Deciduous Forest Phase

Figure 10. Photo courtesy of UWSP taken on 7/1/2020 in Marinette County, WI.

Pure, or mixed, aspen – paper birch community. Understory plants may be only weekly expressed when aspen and paper birch are closely growing and dominant. If seed source is present and canopy openings allow, red maple and young cohorts of balsam fir readily become member of this community. Depending on age within this phase the canopy varies from pure (young) to mixed (older) aspen – paper birch. Disturbance history and seed source will dictate whether aspen or birch dominate this phase.

Dominant plant species

quaking aspen (Populus tremuloides), tree
birch (Betula), tree
red maple (Acer rubrum), tree
balsam fir (Abies balsamea), tree
beaked hazelnut (Corylus cornuta), shrub

State 3
Agricultural State

The Agricultural State consists of a post disturbance establishment of hay, crops, or pasture and a continuation of those practices for many years.

Community 3.1
Agricultural Phase

Continuous cultivation of the site in hay, crops, or pasture for many years.

Transition T1A
State 1 to 2

Reference State

Deciduous Forest State

Stand replacing disturbance that must include fire to create conditions for aspen and paper birch to colonize the site.

Transition T1B
State 1 to 3

Removal of forest cover by whatever means, followed by tilling for agricultural crop production. Establishment of agricultural crops, hay, or pasture following the disturbance.

Restoration pathway R2
State 2 to 1

Deciduous Forest State

Reference State

Deciduous forest community slowly ages out and is invaded by conifers, especially Balsam fir. Other species such as Red maple and Green or Black ash may begin to take hold as well as Aspen and Birch trees die and canopy openings develop.

Transition T2A
State 2 to 3

Removal of forest cover by whatever means, followed by tilling for agricultural crop production. Establishment of agricultural crops, hay, or pasture following the disturbance.

Restoration pathway R3A
State 3 to 1

Cessation of agricultural practices leads to natural reforestation, or site is replanted. Initial species is seed source dependent unless planted. Most likely initial species are Aspen and Red Maple.

Transition T3B
State 3 to 2

Cessation of agricultural practices leads to natural reforestation, or site is replanted. Initial species is seed source dependent unless planted. Most likely initial species are Aspen and Red Maple.
