MLRA notes
Major Land Resource Area (MLRA): 099X–Erie-Huron Lake Plain
This area is in the Eastern Lake Section of the Central Lowland Province of the Interior Plains (USDA-NRCS, 2022). It is a nearly level glacial lake plain with a few scattered ridges of sand that represent past shorelines and moraines. The Saginaw, Clinton, and Huron Rivers empty into the Great Lakes in the part of the area in Michigan. The southern half of this area is covered with glacial deposits of till, lake sediments, and outwash from the Wisconsin and older glacial periods. The area also has some low moraines. Mississippian- to Silurian-age shale, limestone, and dolomite rocks are at or near the surface close to Lake Erie and Lake Huron. Sandstone comes near the surface in the Thumb area east of Saginaw Bay, and a sandstone headland exists on a short stretch of Lake Huron shoreline. An extensive swamp in proximity the Maumee River prevented overland travel prior to its drainage by early settlers. Remnant marshes are near the Lake Erie shore.
The dominant soils in this MLRA are Alfisols, Inceptisols, Mollisols, and Spodosols. The soils in the area dominantly have a mesic soil temperature regime, an aquic soil moisture regime, and mixed or illitic mineralogy. Most soils in MLRA 99 are very deep, generally somewhat poorly drained to very poorly drained, and loamy or clayey. Epiaqualfs (Blount, Hoytville, Nappanee, and Shebeon series) and Glossudalfs (Capac series) formed in till (some of which is dense) on till plains, moraines, and lake plains. Epiaquepts formed in loamy till on till plains and moraines (Kilmanagh series) and in lacustrine deposits on lake plains (Lenawee and Paulding series). Endoaquepts formed in lacustrine deposits on lake plains (Latty and Toledo series) and in loamy till on moraines (Parkhill series). Endoaquolls formed in outwash deposits on outwash plains and lake plains, in drainageways (Granby series), and in loamy till on till plains and moraines (Tappan series). Endoaquods (Pipestone series) formed in outwash deposits on outwash plains, lake plains, and beach ridges. Epiaquods (Wixom series) formed in sandy sediments over till or lacustrine deposits on till plains, outwash plains, and lake plains.
Broad flat areas of somewhat poorly drained soils support Landfire (2017) systems: North-Central Interior Beech-Maple Forest, with wetter patches of North-Central Interior Wet Flatwoods, and Central Interior and Appalachian Swamp. Sandy beach ridges and thin sand flats have Landfire (2017) systems: North-Central Interior Dry-Mesic Oak Forest and Woodland and Great Lakes Wet-Mesic Lakeplain Prairie. Central Interior and Appalachian Floodplain Systems occur adjacent to rivers that flow through the area. To the north, oak systems decline in coverage. Thin sandy flats in the north have Laurentian-Acadian Pine-Hemlock-Hardwood Forest. The north and south are best separated as ecological inference areas due to floristic and dominant vegetation contrasts which also correspond to generally lower summer and winter temperatures northward. This north-south break is approximated by the drainage divide between the Lake Huron and Lake Erie/Lake St. Clair basins.
Nearly three-fourths of this MLRA is in farms. About three-fifths of the area is cropland. The rest of the farmland is mostly in small farm woodlots, but some of the farmland is used for permanent pasture or other purposes. Cash crops are important. Corn, winter wheat, soybeans, and hay are the major crops. Sugar beets and canning crops also are important. Some fruit and truck crops are grown on the coarse textured soils. Dairying is an important enterprise on some farms near the larger cities. Almost one-fifth of the area is used for urban development. Shiawassee National Wildlife Refuge, Cedar Point National Wildlife Refuge, Oak Openings Preserve Metropark (Ohio) are among the more notable conservation lands.

Classification relationships
The USFS ecoregion classification (Cleland et al., 2007) for the majority of MLRA 99 is the Humid Temperate, Hot Continental Division, Midwest Broadleaf Forest Province 222, Lake Whittlesey Glaciolacustrine Plain Section 222U. The ecoregion subsection composition is 222Ud (Sandusky Lake Plain) and 222Ue (Saginaw Clay Lake and Till Plain) in the north near Lake Huron and Saginaw Bay. In the south near Lake Erie, the area is composed of subsections 222Ua (Maumee Lake Plain), 222Ub (Paulding Plains), and 222Uc (Marblehead Drift/Limestone Plain). A mix of interlobate deposits extends into MLRA 99 as subsection 222Jf (Lum Interlobate Moraine) of South Central Great Lakes Section 222J. Sandy deposits extend south from adjacent MLRA are part the Warm Continental Division, Laurentian Mixed Forest Province 212, Northern Lower Peninsula Section 212H, subsection 212Hh (Gladwin Silty Lake Plain).
The Saginaw Bay and Lake Huron lake plains is coextensive with EPA ecoregion 57e (Saginaw Lake Plain) (Omernik and Griffith, 2014). The majority of the Lake Erie or Maumee Lake Plain includes EPA ecoregion 57a (Maumee Lake Plain), extending east to include 57d (Marblehead Drift/Limestone Plain). Large inclusions of sand are delineated as ecoregion 57b (Oak Openings). A significant area of higher clay is designated as 57c (Paulding Plains).
Ecological site concept
The modal concept of the 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, and some may have accumulated carbonates (limnic materials) early in development (generally lower in profile). Vegetation tends to reflect moderate to high fertility in moderately acid sites, but strongly acidic and alkaline, marly sites are very low in fertility have bog-like and fen-like species compositions, respectively.
The distinction between acidic and circumneutral mucks and carbonate rich mucks needs more investigation. Sometimes a lens of oligotrophic rainwater dominates near the surface soil chemistry and vegetation composition, without a strong relationship with marl presence below. Conversely, marl presence is not a necessary indicator of calcareous groundwater dominated soil chemistry or species composition. Intermediate pH reaction classes may be needed to properly delineate soil map units that better reflect species composition.

Climatic features
This ecological site experiences a humid continental climate with mild summers and cold winters. Precipitation is moderately well distributed through the year with higher amounts during the growing season than the winter.
Temperature extremes are moderated in immediate proximity to the Great Lakes, but this moderation has minimal effect inland due to prevailing winds blowing mainly offshore. Mean annual extreme minimum temperatures range from -26.6 to -18.8 °C (-16 to -2 °F), which falls within hardiness zones 5a to 6a (USDA, 2009). In general, temperatures are cooler northward, though local city heat island effects may interrupt this pattern.
The lack of significant topographic relief and general downwind direction to the Great Lakes likely contribute to this MLRA having lower annual precipitation and snowfall compared to the MLRA to the west. Mean annual snowfall ranges from 0.7 to 1.5 m (25 to 55 in). In general, snowfall is highest northward.

Influencing water features
Site remains saturated for most of the year, and may be seasonally ponded to shallow depths.
Wetland description
Mucky Depressions are a generally a function of groundwater seepage and are mostly classified as hydrogeomorphic slope wetlands. Groundwater is generally a stable source of water creating a more or less constant level of saturation. These are usually minerotrophic sources of water that are low in phosphorus and nitrates. Portions of the depression that are isolated from both surface run off and groundwater is subject to mostly rain water, and is lower in minerals (ombrotrophic). Surface runoff near the edges of depression and where ground water sources are shallow can be high in macronutrients (nitrates and phosphates), and is more vulnerable to the eutrophic impacts of fertilizer from adjacent farmlands. Some are influenced by fluctuating lake levels (hydrogeomorphic lacustrine) if adjacent to lakes.
Figure 10.
Soil features
Soils of the Mucky Depressions are very poorly drained organic Histosols or Histic subgroups (peat or muck surface greater than or equal to 20 cm thick), with moderate pH levels. They are commonly classified as Typic Haplosaprists, Terric Haplosaprists, Limnic Haplosaprists, and Histic Humaquepts, and commonly are mapped as Houghton, Carlisle, Adrian, Palms, Edwards, and Martisco series.

Ecological dynamics
Mucks form where net primary productivity greatly exceeds the rate of decomposition due to the lack of oxygen under seasonally or semipermanently saturated conditions. Fens occur under semipermanently saturated conditions, whereas wet meadows prevail under seasonally saturated conditions. Peat accumulation in fens is mostly from dead sedges (Cyperaceae) and brown mosses (Scorpidium scorpioides), while in acid bog sites it is due to peat mosses (Sphagnum spp.). More seasonal hydrology allows more decomposition of brown peat into black muck, and a greater production of plant cover. The thickness of peat and muck is directly related to the duration of non-saturated conditions, whereas longer periods of dryness would tend to result in more thorough decay of organic matter, and a thinner veneer of muck over mineral soil. However, hydrology may change over time, and current muck thickness is as much a legacy of historic hydrology as it is an indicator of current hydrology. Thus, the relationship to present vegetation is only loosely related to muck thickness.
In submergent areas high in dissolved calcium, the green algal genus Chara precipitates calcium carbonate within its cell walls. Over time, dead Chara contributes to the accumulation of marl, which may later become buried in peat and muck.
Michigan Natural Features Inventory (Kost et al., 2010) describes a range of communities that occupy Mucky Depressions, which are arrayed along hydrologic, nutrient, and structural development gradients. Succession from open communities to shrub-dominated through forested communities is kept in check or reversed by fire, beaver activity, and windthrow. However, the rate of succession is slow in the wettest areas, and in areas with more extreme alkalinities or acidities that inhibit nutrient availability.
Fire frequency generally is greatest where adjacent upland sites are oak savanna and prairie rather than closed forest, which was historically the case in the southern half of the MRLA, where prairie fens and wet meadows were most common. Fire has the effect of killing aboveground biomass, and thus conferring an advantage of herbaceous plants over woody species. Graminoids in these open communities provide the main fuels, presuming that standing dead biomass is dry enough to sustain fire. Once a site becomes forested, low understory graminoid cover and thin leaf litter that quickly integrates into the substrate tend to reduce the potential for fire to carry.
The lack of fire adaptation among the dominant tree species is evident from the generally thin bark among the maples.
Beavers (Castor canadensis) affect succession in two distinct ways. First, beavers directly remove trees and shrubs both as a food source and as building materials. Second, beavers may inundate an area via dam building, causing mortality in species of trees and shrubs that are less flood-tolerant. Mucks that occur adjacent to flowing water have the greatest opportunity for beavers to modify water levels.
Windthrow mostly creates single tree gaps. However, swamp forests are more susceptible to large blowdowns than upland sites, because high water tables limit rooting depth and organic substrates are structurally less stable.
The interaction among all these disturbance regimes, including fire, is summarized in the narratives for the broadly defined Central Interior and Appalachian Swamp Systems, and Central Interior and Appalachian Shrub-Herbaceous Wetland Systems Landfire models (USGS, 2008). The ecosystems assignable to swamps were modeled to have a mean fire return interval (probability) of 1,000 years, a beaver flooding interval of 300 years, a patch windthrow interval of 100 years, and a catastrophic windthrow of 600 years. The systems assignable to fens and wet meadows, were modeled to have a fire return interval of 10 years, and a beaver flooding interval of 200 years. A 1,000 year return interval isn’t intended to imply an event taking place regularly every 1,000 years, but rather the probability of 1 out of 1,000 (0.1%) for the event to take place in any given year. As such different patches of the site may not experience the same event simultaneously such that across a large enough area in can be expected that 0.1% of the area could experience the event during an average year. But processes of species dispersal, minimum viable population size, and the species composition of the surrounding landscape (e.g., Driscoll, et al., 2013) must be considered in context of fragmented habitat.
Zonation along a hydrologic gradient is responsible for the maintenance of contrasting plant communities in relative proximity. This also allows for vegetation to respond to short-term changes in climate given the immediate seed source for species in adjacent communities. Several years of increased potential evapotranspiration and lower precipitation can lower local water tables and thereby move the boundaries between zones. These drier conditions are represented by community pathways toward less hydric communities such as from marsh to wet meadows. Likewise, several years with decreased potential evapotranspiration and higher precipitation can raise local water tables, resulting in a shift toward more hydric communities.
The wettest sites are represented by submergent marsh (Nuphar advena - Nymphaea odorata Aquatic Vegetation), but aquatic vegetation such as this are more representative of subaqueous ecological sites rather than Mucky Depressions. Nevertheless, the elements of aquatic vegetation may occur locally among emergent communities.
The emergent marsh (Schoenoplectus tabernaemontani - Typha spp. - (Sparganium spp., Juncus spp.) Marsh, Typha spp. Midwest Marsh) community represents the wettest sites normally found in Mucky Depressions, which are dominated by cattails and bulrushes. Marshes are typically ponded to at least 15 cm during part of the growing season. At higher macronutrient (nitrogen and phosphorous) loadings, cattail productivity may overwhelm the dominance of all other species. Native cattail (Typha latifolia) is outcompeted by non-native cattail (Typha angustifolia) and its hybrid (Typha ×glauca), particularly in higher nutrient or saline conditions. Factors that increase nutrient runoff include agriculture, while road salt is the main cause of saline conditions. The green alga, Chara, is an important submergent component of calcareous marshes. Chara is intolerant of high phosphate or nitrate concentrations, and may disappear when water becomes polluted (Lambert and Davy, 2011).
In areas that are seasonally saturated, southern wet meadow (Carex stricta - Carex spp. Wet Meadow) may form. Wet meadows are dominated by grasses and sedges like Carex stricta, Carex lacustris, Calamagrostis canadensis, but also have a diversity of forbs, including joe pye weed(Eutrochium maculatum), swamp aster (Symphyotrichum puniceum), rough-leaf goldenrod (Solidago patula), and mountain-mint (Pycnanthemum virginianum).
Without beaver activity and occasional fire spilling over from the uplands maintaining the open conditions, trees and shrubs come to dominate the site within 10 to 60 years (USGS, 2011). Marshy sites within Mucky Depression may succeed to a buttonbush (Cephalanthus occidentalis) dominated inundated shrub swamp (Cephalanthus occidentalis / Carex spp. Northern Shrub Swamp) without sufficient disturbance. Wet meadows succeed to shrub-carr (Cornus sericea - Salix spp. - (Rosa palustris) Shrub Swamp).
In the absence of beaver flooding, trees become established and the community succeeds to hardwood swamp (Acer (rubrum, saccharinum) - Fraxinus spp. - Ulmus americana Swamp Forest) after about 80 years. Fluctuating water table favors flood-tolerant silver maple (Acer saccharinum) and green ash (Fraxinus pennsylvanica), and is convergent with floodplain forest in species composition. This community has relatively high fertility in terms of macronutrients like nitrogen and phosphorous. The circumstances responsible for higher fertility in this community relates to pH and hydrology. Having intermediate pH levels (6-7) results in greater nutrient availability, while seasonal fluctuation in water table (oxygenation) can allow a greater turnover in macronutrients accumulated within the substrate. Sites with stable water tables tend to be dominated by red maple (Acer rubrum) and black ash (Fraxinus nigra), and is similar to other peatland communities
in species composition, being relatively nutrient poor. Areas with stable water tables along the northern and western borders may have conifers such as white pine (Pinus strobus) and eastern hemlock (Tsuga canadensis) for hardwood-conifer swamp (Pinus strobus - (Acer rubrum) / Osmunda spp. Swamp Forest). Tree and shrub establishment is most favored in less frequently inundated areas such as on microtopographic highs, which develop later in succession from upturned root masses of wind-toppled trees. Therefore, the wettest portions of a site require longer times for forest to become established.
The prairie fen (Dasiphora fruticosa ssp. floribunda / Carex sterilis - Andropogon gerardi - Arnoglossum plantagineum Fen, Cladium mariscoides - (Carex lasiocarpa, Hypericum kalmianum, Oligoneuron riddellii, Eleocharis elliptica) Fen) occupies areas in which groundwater maintains an almost constant soil saturation without ponding. Topographically elevated sites within the basin may have exposed marl that is more seasonally saturated. Fens support a unique short-statured flora of calcium specialists (calciphiles). The low nutrient environment is driven in part by the high pH levels; the extremely high levels of calcium limits the solubility of phosphorous and iron. The constant hydroperiod from a flow of groundwater maintains anoxic conditions that prevent the release organically stored nutrients.
Without disturbance, fens may succeed through shrub swamp phases to rich tamarack swamp (Larix laricina - Acer rubrum / (Rhamnus alnifolia, Vaccinium corymbosum) Swamp Forest). Continued succession will result in shade-intolerant tamarack (Larix laricina) to be replaced with shade-tolerant red maple (Acer rubrum), and potentially to a version of hardwood swamp. Under prior cooler climatic periods, northern whitecedar (Thuja occidentalis) would succeed tamarack as rich conifer swamp (Thuja occidentalis - Acer rubrum / Cornus sericea Swamp Forest). Rich Conifer Swamp was formerly infrequent in MLRA 98 prior to being cutover, but is more prevalent in adjacent MLRAs to the north (MLRAs 94A and 96). Relict stands of northern whitecedar do still exist in this MLRA, but after widespread logging excessive browse due to increased populations of white-tailed deer (Odocoileus virginianus) has severely limited its ability to regenerate.
More acidic conditions are transitional to peat bog (Chamaedaphne calyculata / Carex oligosperma - Eriophorum virginicum Acidic Peatland), and poor conifer swamp (Picea mariana / Ledum groenlandicum / Carex trisperma / Sphagnum spp. Open Bog Woodland), or another version of hardwood swamp (Acer rubrum, saccharinum) - Fraxinus spp. - Ulmus americana Swamp Forest) with acid indicators like Quercus palustris, Nyssa sylvatica, and Vaccinium corymbosum.
Rare areas with brackish groundwater influenced by Paleozoic salt deposits may be recognized as the Inland Salt Marsh ecological site represented by the Schoenoplectus maritimus - Atriplex patula - Eleocharis parvula Saline Marsh association. However, at present these saline sites have not been delineated as their own map units.
Unconverted stands of wet meadows, marshes, and swamps can be degraded by the addition of excess nutrient runoff, altering species composition; or through the introduction of Eurasian exotics such as purple loosestrife (Lythrum salicaria), reed canarygrass (Phalaris arundinacea), common reed (Phragmites australis ssp. australis), and glossy buckthorn (Frangula alnus).
Conversion to cropland involves the drainage of the land, followed by removal of vegetation, plowing the upper 20 to 30 cm of soil, and introduction of fertilizer. Results of an unpublished dynamic soil properties study conducted in 2015 by the Grand Rapids Soil Survey Office (in cooperation with the National Soil Science Lab in Lincoln, NE), suggests that farming mucky soils can result in soil becoming heavily compacted, high in nitrates and low in carbon-to-nitrogen ratios. Sites restored with native plants and with the hydrology partially restored, retained the higher nutrient levels and compaction characteristic of actively cultivated sites. Despite restoration with native plants, formerly cultivated sites may have significant coverage of invasive reed canarygrass (Phalaris arundinacea). Although opportunities of seed dispersal and disturbances are factors in invasive species presence, other studies suggest a connection with the high nutrient loads (Green and Galowitch, 2002).
The emerald ash borer (Agrilus planipennis) is causing a major transition in plant composition through the mortality of green ash (Fraxinus pennsylvanica) and black ash (Fraxinus nigra) from silver maple-green ash hardwood swamp to red maple-tamarack swamp phases respectively. The introduced pest causes 100 percent mortality of stems greater than 2.5 cm in diameter within five to ten years of infestation. This mortality will reduce the frequency of reproductively mature trees and thereby severely limit new seed production. As of 2020, many former ash stands have no living ash stems greater than 10 cm, but have vigorous seedling and sapling layers, and some basal sprouts from adult trees. There are some signs of success from biocontrol studies using introduced parasitoid wasps, but models of worst-case scenarios show the potential extirpation of ash populations within the next 30 years (Kappler et al., 2019).

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.

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
Semi-natural Drained State
The Semi-natural 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.

Interpretations
Animal community
Mammals
Large Herbivores
The largest herbivore in the region is white-tailed deer (Odocoileus virginianus), a browser that occupies a wide range of cover phases in all but the most inundated habitats. Agricultural conversion and forest fragmentation, both of which are favorable to deer forage, and the extirpation of most natural predators has resulted in excess populations of deer across the entire area. Excess deer browse limits the continued recruitment of northern whitecedar (Thuja occidentalis) into the overstory and severely reduces the diversity of forbs in the understory.
Large Predators
Formerly, gray wolf (Canis lupus), American black bear (Ursus americanus), and cougar (Puma concolor), were among the top predators occupying adjacent uplands. By the late 1800s, these species were extirpated from the area through excess hunting and habitat conversion. Bobcat (Lynx rufus) and fisher (Pekania pennanti) ranked among the medium-sized predators until they too were extirpated by the late 1800s. However, bear and bobcats are occasionally present at the northern end of the MLRA.
At present, the only native carnivore capable of preying on deer is the coyote (Canis latrans), which occupies all community phases. Medium-sized mammalian predators include gray fox (Urocyon cinereoargenteus) and red fox (Vulpes vulpes), both of which occupy a wide range of community phases, but on balance, gray fox prefers more forested phases than red fox. Racoon are ubiquitous mid-sized omnivores that spend a large in swampy habitat hunting burrowing crayfish among other animals.
Small Mammals
Beaver (Castor canadensis) is a keystone species of swamp and marsh for its ecological engineering of landscapes. Beavers can be responsible for consuming trees and shrubs of the more woody community phases, converting them to marsh and meadow phases. They also, by damming streams, may increase the water table, and move from saturated swamp, wet meadow, and fen phases to phases to semipermanently ponded marsh and inundated shrub swamp phases. Cottonwood (Populus spp.), willows (Salix spp.), alder (Alnus rugosa), yellow birch (Betula alleghaniensis), grasses (Poaceae), and smartweeds (Persicaria spp.).
Muskrats (Ondatra zibethicus) construct dens using cattails and sedges in the marsh phase.
Bats (family Vespertilionidae) may forage at night in and around wetlands, which are often a hub for flying insects, many of which have aquatic larvae. Many bats roost in summer in cavities and under tree bark, thus requiring forests with some large mature trees and snags. A healthy population of bats provides an important ecosystem service by reducing crop pest populations and reducing the need for pesticide applications.
Birds
Commonly encountered birds foraging in marshy phases are Red-winged Blackbird (Agelaius phoeniceus) and Swamp Sparrow (Melospiza georgiana), which nest in shrubs. Tree Swallow (Hirundo rustica) are aerial predators over open water and nest in tree cavities. Green Heron (Butorides virescens) and Great Blue Heron (Ardea herodias) hunt for small aquatic animals in shallow water, and nest in trees. Wood Duck (Aix sponsa) nest in cavities of larger trees and snags of swamp forests, and may patrol vernal pools within swamp forests or open marshes.
Common species foraging and nesting in shrubbier phases include Gray Catbird (Dumetella carolinensis), Common Yellowthroat (Geothlypis trichas), and Yellow Warbler (Setophaga petechia).
Larger birds that nest in large trees and snags of swamp forests include Red-shouldered Hawk (Buteo lineatus), Barred Owl (Strix varia) and Pileated Woodpecker (Dryocopus pileatus). Generalist forest songbirds occurring in swamp forests include White-breasted Nuthatch (Sitta carolinensis), Wood Thrush (Hylocichla mustelina), Eastern Wood-Pewee (Contopus virens), Rose-breasted Grosbeak (Pheucticus ludovicianus), Black-capped Chickadee (Poecile atricapillus), and Baltimore oriole (Icterus galbula). Forest and woodland songbirds with an affinity for swamp forest include Warbling Vireo (Vireo gilvus) Cerulean Warbler (Setophaga cerulea), Northern Waterthrush (Parkesia noveboracensis).
According to Neimi et al (2009) the following birds are more tolerant of disturbed wetlands: Common grackle (Quiscalus quiscula), American robin (Turdus migratorius), European starling (Sturnus vulgaris), Northern cardinal (Cardinalis cardinalis), Mallard (Anas platyrhynchos), American goldfinch (Carduelis tristis), Mourning dove (Zenaida macroura), Marsh wren (Cistothorus palustris), Gray catbird (Dumetella carolinensis), Baltimore oriole (Icterus galbula), Brown-headed cowbird (Molothrus ater), and Killdeer (Charadrius vociferus).
Similarly, the following birds are associated with higher quality wetlands: Swamp sparrow (Melospiza georgiana), Common yellowthroat (Geothlypis trichas), Sandhill crane (Grus canadensis), Sedge wren (Cistothorus platensis), Alder flycatcher (Empidonax alnorum), Bobolink (Dolichonyx oryzivorous), American redstart (Setophaga ruticilla), Bald eagle (Haliaeetus leucocephalus), Northern harrier (Circus cyaneus), Brown thrasher (Toxostoma rufum), and White-throated sparrow (Zonotrichia albicollis).
Reptiles
Common snakes such as ribbon and garter (Thamnophis spp.) prey upon soft invertebrates and amphibian among all cover types (community phases) on land and occasionally in the water. Eastern massasauga (Sistrurus catenatus catenatus), the region’s only significantly venomous species, occupies a mixture of cover types, but is frequently associate with open upland phases during cooler periods. Massaugas require the flowing groundwater to prevent their subterranean hibernacula from freezing over the winter. Kirtland's Snake (Clonophis kirtlandii) is a rare snake that occupies crayfish burrows in prairie fens, open tamarack swamps, and sedge meadows, mostly in the southern half of the MLRA.
Several species of turtles may transit through mucky depressions between upland nesting sites and aquatic environments. Spotted turtle (Clemys guttata) has affinity to fens and tamarack swamps, and is of conservation concern. The mainly terrestrial box turtle (Terrapene carolina) can be found foraging within the non-inundated habitat within mucky depressions.
Amphibians
The seasonally ponded areas associated with this ecological site provide potentially important fish-free pools for the development of amphibian larvae. Amphibians most frequently encountered in wooded community phases are wood frogs (Lithobates sylvaticus) and gray treefrogs (Hyla versicolor and H. chrysoscelis). Four-toed Salamander (Hemidactylium scutatum) can be seen breeding in the fall, and will lay their eggs along the banks of ponded areas in the spring. Blanchard's cricket frog (Acris crepitans blanchardi) is a rare frog found in the open community phases.
Invertebrates
Among the thousands of invertebrates that that occupy habitats within this ecological site, Hine's Emerald (Somatochlora hineana) and Tamarack tree cricket (Oecanthus laricis) have particular affinity for this type of habitat. Hine's Emerald is a dragonfly of note due to its habitat restriction to bogs and fens. The larvae of this dragonfly inhabit burrowing crayfish burrows. Tamarack tree cricket is a rare cricket found in the tamarack community phase.
Domesticated Livestock
This ecological site is not a significant host for domesticated livestock. Substrate likely too wet unless drained.
The references consulted for wildlife habitat suitability are MNFI (2020), Harding (1997), Reid (2006), Van Dersal (1938); Roberts and Arner (1984), Cornell Lab of Ornithology (2020).
Hydrological functions
Mucky depressions function as hydrologic discharge areas.
Recreational uses
Recreational opportunities are mainly hunting, hiking, botanizing, and bird watching, assuming waterproof footwear. Saturated mucky substrate creates issues with camping. Abundant mosquitoes may compromise user experience during the warmer seasons.
Wood products
Red Maple (Acer rubrum)
Red maple is managed through a variety of silvicultural systems, including clearcutting, and regenerates by stump sprouting, but sometimes suppressed with herbicide and fire where oak is more desired.
Wood is used for furniture and cabinetry. It makes a moderate-density firewood (dry specific gravity: 0.54).
Swamp White Oak (Quercus bicolor)
Swamp white oak is managed by shelterwood harvest.
Wood is grouped with other related white oaks, is used in furniture, and is uniquely suitable (above all other woods) for its use in wine barrels. It makes a high-density firewood (dry specific gravity: 0.72).
Silver Maple (Acer saccharinum)
Silver maple readily regenerates from seed on moist soils of its natural habitat. Silver maple breaks easily due to brittle wood, and is not typically harvested for wood products. It makes a moderate-density firewood (dry specific gravity: 0.47).
Yellow Birch (Betula alleghaniensis)
Yellow birch naturally regenerates on rotting logs under moist shaded conditions. After the roots reach soil below the log, which eventually decays, several roots may prop the tree over an empty space. Mechanical soil scarification or prescribed fire can be used to prepare a suitable seed bed in absence of advance regeneration. Yellow birch lumber and veneer is made into furniture, tool handles, and interior paneling and frames. It makes a high-density firewood (dry specific gravity: 0.62).
Black Ash (Fraxinus nigra)
Black ash naturally regenerates by seed in open moist soils of swamps. Trees suffer heavy mortality from emerald ash borer. Black ash is slow growing small tree not commonly used for wood products. It makes a moderate-density firewood (dry specific gravity: 0.49).
Green Ash (Fraxinus pennsylvanica)
Green ash usually has advanced regeneration (seedling and saplings in understory prior to harvest), and is also able to stump sprout. Trees suffer heavy mortality from emerald ash borer. Green ash wood is well suited as tool handles and baseball bats due to its hardness and bending qualities. It makes a moderate-density firewood (dry specific gravity: 0.56).
Tamarack (Larix laricina)
Tamarack naturally regenerates by seed on open moist soil. It is very intolerant of shade and drought, so artificial regeneration is most successful by planting seedlings germinated in a greenhouse for the first year. Most typical commercial uses of tamarack is wood pulp for making paper, but its rot resistance makes it suitable for fence posts and railroad ties. It is a moderate-density firewood (dry specific gravity: 0.53).
Black Willow (Salix nigra)
Black willow naturally regenerates immediate by seed on open moist soil (seeds have a short viability window). It is usually artificially regenerated by cuttings, which root easily in wet soil. Black willow wood is easily worked and doesn’t splinter. It is typically used for crates and boxes or small carvings. It makes a low-density firewood (dry specific gravity: 0.39).

Supporting information
Inventory data references
Since 2011, the Grand Rapids Soil Survey Office has collected 350 points with quantitative vegetation data throughout MLRAs 97 and 98, in coordination with soil survey projects, or opportunistically with incidental technical soil service requests (i.e. wetland redeterminations). Of these, 52 points (15%) represent sites on organic soils of MLRAs 97 and 98. This data was used to inform community composition for the MLRA 98 Mucky Depression ESD (F098XA006MI) in 2020. Additional data was collected within MLRA 99 in 2021.
Data were analyzed with R statistical software using numerical taxonomy tools. Species cover among four strata were aggregated into a single stratum and then log-transformed. Several clustering methods were evaluated, and optimal groupings were arrived via flexible-beta method of agglomerative hierarchical clustering using Bray-Curtis dissimilarity among plots as input. We identified nine clusters, which corresponded with six phases of the reference state, and two phases of alternative states. The composition of plots within each of these clusters was aggregated to populate the species composition tables of those phases. The two plots inventoried within MLRA 99 were given ten times the weight of MLRA 97 and 98 plots for the purpose of species abundance tables. All documented species were included unless their estimated maximum cover (85th percentile where present, and adjusted downward for frequency less than 70%) fell below 0.1%. Non-native species were omitted from the species tables for all community phases within the reference state, which ideally should not have non-native species (most of the time, if non-native species constituted a dominant cover, cluster analysis would have grouped the plot with an alternative community phase). Phases not characterized with plot data were identified based on literature and undocumented field observations.

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.
