MLRA notes
Major Land Resource Area (MLRA): 098X–Southern Michigan and Northern Indiana Drift Plains
This area is in the Eastern Lake Section of the Central Lowland Province of the Interior Plains. It is a broad glaciated plain that is deeply mantled by till in the north and outwash to the south. Much of the area is nearly level to gently rolling. Elevation ranges from 183 to 391 m (600 to 1285 ft). Local topographic relief averages 9 m and ranges up to 74 m (30 to 245 ft). Highest relief occurs adjacent to river valleys eroded through moraines. Topography is more subdued south of the Atlantic/Gulf drainage divide near the Michigan/Indiana state line, elevations ranging from 185 to 280 m (605 to 920 ft). Local topographic relief in the south averages 4 m and ranges up to 49 m (10 to 160 ft).
The surface of this area is covered by 30 to 150 m (100 to 500 ft) of glacial drift in most areas. At the northern edge of the area, the drift is more than 100 meters (300 ft) thick. From the Grand River basin northward, most of the drift consists of till from the Saginaw Lobe of the Wisconsin Ice Sheet. From the Kalamazoo River basin southward, there are significant deposits of unconsolidated sand and gravel outwash formed between major lobes of the receding Wisconsin Ice Sheet. The outwash deposits are reworked as sand dunes in the Kankakee River basin.
The bedrock beneath the glacial deposits in this area is deformed in the shape of a basin. The center of this basin is in the north-central part of the area. Pennsylvanian-age sandstone are in the center of the basin, and Mississippian-age sandstone and shale beds form the outer rings of the basin. In a few areas the drift deposits are less than 2 m (6 ft) thick, where glacial outwash channels have eroded to limestone bedrock in Grand Rapids, and where sandstone bedrock cuestas peak in elevation in near Hillsdale, Michigan. A sandstone cliff < 15 m high (<50 ft) occurs along a short stretch of the Grand River in Grand Ledge, Michigan.
Most of the rivers in this area are short because of their proximity to the Great Lakes east and west of the area. The largest watersheds, the St. Joseph River, Grand River, and Kalamazoo River drain into Lake Michigan. The southern extent of the MLRA is drained by the Kankakee River of the Mississippi River watershed.
Classification relationships
Among the USFS ecoregional framework (Cleland et al., 2007), most of MLRA 98 is represented by the Humid Temperate Domain (200), Hot Continental Division (220), Midwest Broadleaf Forest Province (222), South Central Great Lakes Section (222J), subsections 222Jc, 222Jg, 222Jh, and 222Jf. Similar sites within the portion of MLRA 98 that overlap the Prairie Division (250) and Prairie Parkland Province
(251) are treated as separate ecological sites. MLRA 98 recently was adjusted to exclude portions of Warm Continental Division (210), Laurentian Mixed Forest Province (212) to the north, and subsections 222Ja and 222Jb to the northwest.
Among the EPA ecoregional framework (Omernik and Griffith, 2014), most of MLRA 98 falls within Eastern Temperate Forests (Level I: 8), Mixed Wood Plains (Level II: 8.1), Southern Michigan/Northern Indiana Drift Plains (Level III: 56), and Level IV: 56b, 56g, and 56h. Similar sites within the portion of MLRA 98 that overlap the Central USA Plains (Level II: 8.2) and Central Corn Belt Plains (Level III: 54) are treated as separate ecological sites. MLRA 98 recently was adjusted to exclude portions of Northern Forests (Level I: 5), Mixed Wood Shield (Level II: 5.2), Northern Lakes and Forests (Level III: 50) to the north, and level IV: 56d and 56f to the northwest.
Ecological site concept
The central concept of the Kankakee Mucky Depressions is organic soils (typically muck) of intermediate pHs (5-7). Small delineations occur as base slope seeps. May occur on former lake beds as organic flats with minerotrophic ground water influence, but without marl. A variety of higher or lower fertility marshes and shrub swamps may form, but wetness and fire frequency limits the degree to which swamp forest can form.

Climatic features
This ecological site experiences a humid continental climate with warm summers and cold winters. Precipitation is moderately well distributed through the year with higher amounts during the growing season than the winter. This ecological site is distributed only along the southern portion of the MLRA, and consequently is outside the moderating envelope of the Great Lakes. This area does have slightly greater annual rainfall due to being slightly closer to the main source of moisture (the Gulf of Mexico) than the rest of the MLRA, but this trend is canceled out by higher potential evapotranspiration rates. More significantly, this area has lower snowfall, warmer summer temperatures, and more frequent lightning, all of which contribute to higher fire frequencies than northern portions of the MLRA.

Ecological dynamics
Fire was frequent in context with adjacent prairie and oak savanna, and supported a wet meadow community. Wetter sites supported buttonbush swamps. Wet anoxic soils favor facultative and obligate wetland species. The reference community is dominated by buttonbush (Cephalanthus occidentalis) and uptight sedge (Carex stricta).

State 1
Reference State
The Reference State consists of a spontaneous wild condition wherein non-native species are of low abundance and all native species retain viable populations. Structure and function of communities vary according to natural processes and disturbance regimes, with human influences limited to drivers that have the similar outcomes as natural processes. Communities range from marshes and fens to hardwood swamps. Dominant natural processes and disturbance regimes include fire, wind, and beaver activities.
Dominant plant species
-
common buttonbush (Cephalanthus occidentalis), shrub

Wet Meadow: Carex stricta - Carex spp. Wet Meadow
This phase represents open vegetation that is moderately fertile and has a high diversity of species. It is created through tree and shrub mortality due to beaver activity and is maintained by fire. Fire every ten years or so is required to maintain this phase without tree and shrub encroachment. Larger patches with interiors more distant from potential tree seed sources may persist for greater periods. After about 60 years after disturbance, vegetation succeeds to shrub swamp.
Forest overstory. The overstory has less than 5 percent tree cover.
Forest understory. Understory vegetation is dense and graminoid dominated with various species of grasses, sedges, and forbs.
Dominant plant species
-
upright sedge (Carex stricta), grass

Fen: Dasiphora fruticosa ssp. floribunda / Carex sterilis - Andropogon gerardi - Arnoglossum plantagineum Fen
This phase represents open conditions with a stable calcareous hydrology or exposed marl. Species composition and low stature strongly reflect the low nutrient availability.
Forest overstory. Overstory is mostly treeless, but scattered tamarack (Larix laricina) may approach 5 percent cover. Poison sumac (Toxicodendron vernix) occasionally approaches tree size.
Forest understory. Understory consists of dwarf shrubs like shrubby cinquefoil (Dasiphora fruticosa) and Kalm’s St. Johnswort (Hypericum kalmianum), and graminoids like twigrush (Cladium mariscoides), wooly sedge (Carex pellita), and yellow sedge (Carex flava). Many of the species are calciphiles (calcium indicators). The wax-myrtle (Morella pensylvanica) is a locally rare nitrogen-fixing shrub found in the margins of large fens.

State 2
Cultural State
The cultural state is actively managed. The structure and composition of cultural vegetation is not self-sustaining without human inputs.
Community 2.1
Sustainable Crop, Pasture, or Plantation
The community phase is an undifferentiated placeholder representing any of a number of possible crops or other intensive land uses in which best available management practices are employed to ensure that a minimum amount of soil erosion and water pollution occurs.
Community 2.2
Unsustainable Cultural Phase
The community phase is an undifferentiated placeholder representing any of a number of possible crops or other intensive land uses in which poor management practices are employed, resulting in an unacceptable amount of soil erosion and water pollution.
Community 2.3
Conservation Feature
The community phase represents non-crop vegetation that is managed in association with cropland or other intensive land uses to reduce environmental impacts of the land use. The managed vegetation can be a grassed waterway, conservation reserve, a small patch pollinator garden, or other land taken out of crop production. The small size and adjacency to an intensive land uses limits the degree to which native biological community and associated ecosystem services can be restored, but in a landscape context it may provide buffers or connectivity with nearby wild ecosystems.

State 3
Seminatural Drained State
The Seminatural Drained State is modified from reference conditions by draining the site, often followed by temporary cultivation of the site. The vegetation is spontaneously self-generated or self-sustaining in response to both human and natural drivers. However, species composition may no longer indicate wetland definitions, and may consist of a mix of native and introduced species. The degree of isolation from intact habitat and the degree of disturbance will dictate the species composition as vegetation recovers.

State 4
Seminatural State
The Seminatural State is modified from reference conditions mainly in species composition due to some type of disturbance, but retains a wetland hydrology. The state might have been drained and under cultivation for a time, but subsequently, hydrology is at least partially restored. The vegetation is spontaneously self-generated or self-sustaining in response to both human and natural drivers. However, species composition consists of a mix of native and introduced species. The degree of isolation from intact habitat and the degree of disturbance will dictate the species composition as vegetation recovers.

Site Development and Testing Plan
Future work is needed, as described in a future project plan, to validate the information presented in this provisional ecological site description. Future work includes field sampling, data collection and analysis by qualified vegetation ecologists and soil scientists. As warranted, annual reviews of the project plan can be conducted by the Ecological Site Technical Team. A final field review, peer review, quality control, and quality assurance reviews of the ESD are necessary to approve a final document.

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.

Indicators
-
Number and extent of rills:
-
Presence of water flow patterns:
-
Number and height of erosional pedestals or terracettes:
-
Bare ground from Ecological Site Description or other studies (rock, litter, lichen, moss, plant canopy are not bare ground):
-
Number of gullies and erosion associated with gullies:
-
Extent of wind scoured, blowouts and/or depositional areas:
-
Amount of litter movement (describe size and distance expected to travel):
-
Soil surface (top few mm) resistance to erosion (stability values are averages - most sites will show a range of values):
-
Soil surface structure and SOM content (include type of structure and A-horizon color and thickness):
-
Effect of community phase composition (relative proportion of different functional groups) and spatial distribution on infiltration and runoff:
-
Presence and thickness of compaction layer (usually none; describe soil profile features which may be mistaken for compaction on this site):
-
Functional/Structural Groups (list in order of descending dominance by above-ground annual-production or live foliar cover using symbols: >>, >, = to indicate much greater than, greater than, and equal to):
Dominant:
Sub-dominant:
Other:
Additional:
-
Amount of plant mortality and decadence (include which functional groups are expected to show mortality or decadence):
-
Average percent litter cover (%) and depth ( in):
-
Expected annual annual-production (this is TOTAL above-ground annual-production, not just forage annual-production):
-
Potential invasive (including noxious) species (native and non-native). List species which BOTH characterize degraded states and have the potential to become a dominant or co-dominant species on the ecological site if their future establishment and growth is not actively controlled by management interventions. Species that become dominant for only one to several years (e.g., short-term response to drought or wildfire) are not invasive plants. Note that unlike other indicators, we are describing what is NOT expected in the reference state for the ecological site:
-
Perennial plant reproductive capability:
