Hydric Soil Indicators: (Applicable to all LRRs, unless otherwise noted.)

Indicators for Problematic Hydric Soils3:

In Histosols, typically 16 inches (40 cm) or more of the upper 32 inches (80 cm) is organic soil material or that have organic soil material of any thickness over rock or fragmental soil material that has interstices filled with organic soil material. This indicator does not include Folists: freely drained Histosols that are saturated with water for less than 30 cumulative days during normal years (and are not artificially drained).

Histosol (A1)

A gleyed matrix that occupies 60 percent or more of a layer starting at a depth ≤6 inches (15 cm) from the soil surface.

Sandy Gleyed Matrix (S4)

A layer of muck 0.75 inch (2 cm) or more thick with value of 3 or less and chroma of 1 or less, starting at a depth ≤6 inches (15 cm) from the soil surface.

2 cm Muck (A10) (LRR A, E)

A histic epipedon underlain by mineral soil material with chroma of 2 or less. Most histic epipedons are surface horizons 8 inches (20 cm) or more thick of organic soil material. Aquic conditions or artificial drainage are required; however, aquic conditions can be assumed if indicators of hydrophytic vegetation and wetland hydrology are present.

Histic Epipedon (A2)

A layer starting at a depth ≤6 inches (15 cm) from the soil surface that is at least 4 inches (10 cm) thick and has a matrix with 60 percent or more chroma of 2 or less and 2 percent or more distinct or prominent redox concentrations occurring as soft masses and/or pore linings.

Sandy Redox (S5)

On flood plains, a layer 4 inches (10 cm) or more thick with 40 percent or more chroma of 2 or less and 2 percent or more distinct or prominent redox concentrations occurring as soft iron-manganese masses with diffuse boundaries. The layer starts at a depth ≤8 inches (20 cm) from the soil surface. Iron- manganese masses have value and chroma of 3 or less. Most commonly, they are black. The thickness requirement is waived if the layer is the mineral surface layer.

Iron-Manganese Masses (F12) (LRR D)

A layer of peat, mucky peat, or muck 8 inches (20 cm) or more thick that starts at a depth of ≤6 inches (15 cm) from the soil surface; has hue of 10YR or yellower, value of 3 or less, and chroma of 1 or less; and is underlain by mineral soil material with chroma of 2 or less.

Black Histic (A3)

A layer starting at a depth ≤6 inches (15 cm) from the soil surface in which iron-manganese oxides and/or organic matter have been stripped from the matrix and the primary base color of the soil material has been exposed. The stripped areas and translocated oxides and/or organic matter form a faintly contrasting pattern of two or more colors with diffuse boundaries. The stripped zones are 10 percent or more of the volume and are rounded.

Stripped Matrix (S6)

A layer derived from red parent materials that is at least 4 inches (10 cm) thick, starting at a depth ≤10 inches (25 cm) from the soil surface with a hue of 7.5YR or redder. The matrix has a value and chroma greater than 2 and less than or equal to 4. The layer must contain 10 percent or more depletions and/or distinct or prominent redox concentrations occurring as soft masses or pore linings. Redox depletions should differ in color by having: a. Value one or more higher and chroma one or more lower than the matrix, or b. Value of 4 or more and chroma of 2 or less.

Red Parent Material (F21)

A hydrogen sulfide odor starting at a depth ≤12 inches (30 cm) from the soil surface.

Hydrogen Sulfide (A4)

A layer of mucky modified loamy or clayey soil material 4 inches (10 cm) or more thick starting at a depth ≤6 inches (15 cm) from the soil surface.

Loamy Mucky Mineral (F1) (except MLRA 1)

In depressions and and flood plains subject to frequent ponding and/or flooding, one of the following must be observed: a. If bedrock occurs between 6 inches (15 cm) and 10 inches (25 cm) of the soil surface, a layer at least 6 inches (15 cm) thick starting at a depth ≤4 inches (10 cm) from the soil surface with a value 2.5 or less and chroma 1 or less, and the remaining soil to bedrock must have the same colors as above or any other color that has chroma of 2 or less. b. If bedrock occurs at a depth ≤6 inches (15 cm) from the soil surface, more than half of the soil thickness must have value 2.5 or less and chroma 1 or less and the remaining soil to bedrock must have the same colors as above or any other color that has chroma of 2 or less.

Very Shallow Dark Surface (F22)

A layer of muck 0.5 inch (1 cm) or more thick with value of 3 or less and chroma of 1 or less, starting at a depth ≤6 inches (15 cm) from the soil surface.

1 cm Muck (A9) (LRR D, G)

A gleyed matrix that occupies 60 percent or more of a layer starting at a depth ≤12 inches (30 cm) from the soil surface.

Loamy Gleyed Matrix (F2)

Other (Explain in Remarks)

A layer with a depleted or gleyed matrix that has 60 percent or more chroma of 2 or less, starting at a depth ≤12 inches (30 cm) from the soil surface, and having a minimum thickness of either: a. 6 inches (15 cm), or b. 2 inches (5 cm) if the 2 inches consists of fragmental soil material. Organic, loamy, or clayey layer(s) above the depleted or gleyed matrix must have value of 3 or less and chroma of 2 or less starting at a depth ≤6 inches (15 cm) from the soil surface and extend to the depleted or gleyed matrix. Any sandy material above the depleted or gleyed matrix must have value of 3 or less and chroma of 1 or less starting at a depth ≤6 inches (15 cm) from the soil surface and extend to the depleted or gleyed matrix. Viewed through a 10x or 15x hand lens, at least 70 percent of the visible sand particles must be masked with organic material. Observed without a hand lens, the sand particles appear to be close to 100 percent masked. A, E, and calcic horizons may have low chromas and high values and may therefore be mistaken for a depleted matrix; however, they are excluded from the concept of depleted matrix unless the soil has common or many distinct or prominent redox concentrations occurring as soft masses or pore linings. The low-chroma matrix must be the result of wetness and not a weathering or parent material feature.

Depleted Below Dark Surface (A11)

A layer that has a depleted matrix with 60 percent or more chroma of 2 or less and that has a minimum thickness of either: a. 2 inches (5 cm) if the 2 inches starts at a depth ≤4 inches (10 cm) from the soil surface, or b. 6 inches (15 cm), starting at a depth ≤10 inches (25 cm) from the soil surface. A, E, and calcic horizons may have low chromas and high values and may therefore be mistaken for a depleted matrix; however, they are excluded from the concept of depleted matrix unless the soil has common or many distinct or prominent redox concentrations occurring as soft masses or pore linings. The low-chroma matrix must be the result of wetness and not a weathering or parent material feature.

Depleted Matrix (F3)

A layer at least 6 inches (15 cm) thick with a depleted or gleyed matrix that has 60 percent or more chroma of 2 or less starting below 12 inches (30 cm) of the surface. The layer(s) above the depleted or gleyed matrix and starting at a depth ≤6 inches (15 cm) from the soil surface must have value of 2.5 or less and chroma of 1 or less to a depth of at least 12 inches (30 cm) and value of 3 or less and chroma of 1 or less in any remaining layers above the depleted or gleyed matrix. In any sandy material above the depleted or gleyed matrix, at least 70 percent of the visible soil particles must be masked with organic material, viewed through a 10x or 15x hand lens. Observed without a hand lens, the particles appear to be close to 100 percent masked. A, E, and calcic horizons may have low chromas and high values and may therefore be mistaken for a depleted matrix; however, they are excluded from the concept of depleted matrix unless the soil has common or many distinct or prominent redox concentrations occurring as soft masses or pore linings. The low- chroma matrix must be the result of wetness and not a weathering or parent material feature.

Thick Dark Surface (A12)

A layer that is at least 4 inches (10 cm) thick, starting at a depth ≤8 inches (20 cm) from the mineral soil surface, and has: a. Matrix value of 3 or less and chroma of 1 or less and 2 percent or more distinct or prominent redox concentrations occurring as soft masses or pore linings, or b. Matrix value of 3 or less and chroma of 2 or less and 5 percent or more distinct or prominent redox concentrations occurring as soft masses or pore linings.

Redox Dark Surface (F6)

3Indicators of hydrophytic vegetation and

A layer of mucky modified sandy soil material 2 inches (5 cm) or more thick starting at a depth ≤6 inches (15 cm) from the soil surface.

Sandy Mucky Mineral (S1)

Redox depletions with value of 5 or more and chroma of 2 or less in a layer that is at least 4 inches (10 cm) thick, starting at a depth ≤8 inches (20 cm) from the mineral soil surface, and has: a. Matrix value of 3 or less and chroma of 1 or less and 10 percent or more redox depletions, or b. Matrix value of 3 or less and chroma of 2 or less and 20 percent or more redox depletions. Care should be taken not to mistake mixing of an E or calcic horizon into the surface layer for depletions. The “pieces” of E and calcic horizons are not redox depletions.

Depleted Dark Surface (F7)

wetland hydrology must be present,

A layer of mucky peat or peat 1 inch (2.5 cm) or more thick with value of 4 or less and chroma of 3 or less, starting at a depth ≤6 inches (15 cm) from the soil surface, and underlain by sandy soil material.

2.5 cm Mucky Peat or Peat (S2) (LRR G)

In closed depressions subject to ponding, 5 percent or more distinct or prominent redox concentrations occurring as soft masses or pore linings in a layer that is 2 inches (5 cm) or more thick and starts at a depth ≤4 inches (10 cm) from the soil surface.

HYDROLOGY

Wetland Hydrology Indicators:

Primary Indicators (minimum of one is required; check all that apply)

Secondary Indicators (2 or more required)

This indicator consists of the direct, visual observation of surface water (flooding or ponding) during a site visit.

Surface Water (A1)

Water-stained leaves are fallen or recumbent dead leaves that have turned grayish or blackish in color due to inundation for long periods.

Water-Stained Leaves (B9) (except

Water-stained leaves are fallen or recumbent dead leaves that have turned grayish or blackish in color due to inundation for long periods.

Water-Stained Leaves (B9) (MLRA 1, 2

This indicator consists of the direct, visual observation of the water table 12 inches (30 cm) or less below the surface in a soil pit, auger hole, or shallow monitoring well. This indicator includes water tables derived from perched water, throughflow, and discharging groundwater (e.g., in seeps) that may be moving laterally near the soil surface.

High Water Table (A2)

MLRA 1, 2, 4A, and 4B)

4A, and 4B)

Visual observation of saturated soil conditions 12 inches (30 cm) or less from the soil surface as indicated by water glistening on the surfaces and broken interior faces of soil samples removed from the pit or auger hole. This indicator must be associated with an existing water table located immediately below the saturated zone; however, this requirement is waived under episaturated conditions if there is a restrictive soil layer or bedrock within 12 inches (30 cm) of the surface.

Saturation (A3)

Salt crusts are hard or brittle deposits of salts formed on the ground surface due to the evaporation of saline surface water.

Salt Crust (B11)

This indicator consists of flow patterns visible on the soil surface or eroded into the soil, low vegetation bent over in the direction of flow, absence of leaf litter or small woody debris due to flowing water, and similar evidence that water flowed across the ground surface.

Drainage Patterns (B10)

Water marks are discolorations or stains on the bark of woody vegetation, rocks, bridge supports, buildings, fences, or other fixed objects as a result of inundation.

Water Marks (B1)

Presence of numerous live individuals, diapausing insect eggs or crustacean cysts, or dead remains of aquatic invertebrates, such as clams, aquatic snails, aquatic insects, ostracods, shrimp, and other crustaceans, either on the soil surface or clinging to plants or other emergent objects.

Aquatic Invertebrates (B13)

Visual observation of the water table between 12 and 24 inches (30 and 60 cm) below the surface during the normal dry season or during a drier-than-normal year.

Dry-Season Water Table (C2)

Sediment deposits are thin layers or coatings of fine-grained mineral material (e.g., silt or clay) or organic matter (e.g., pollen), sometimes mixed with other detritus, remaining on tree bark, plant stems or leaves, rocks, and other objects after surface water recedes.

Sediment Deposits (B2)

A hydrogen sulfide (rotten egg) odor within 12 inches (30 cm) of the soil surface. Note: If macros are disabled, check this blank if you have hydric soil indicator Hydrogen Sulfide (A4) checked.

Hydrogen Sulfide Odor (C1)

One or more recent aerial photographs or satellite images indicate soil saturation. Saturated soil signatures must correspond to field-verified hydric soils, depressions or drainage patterns, differential crop management, or other evidence of a seasonal high water table.

Saturation Visible on Aerial Imagery (C9)

Drift deposits consist of rafted debris that has been deposited on the ground surface or entangled in vegetation or other fixed objects. Debris consists of remnants of vegetation (e.g., branches, stems, and leaves), man-made litter, or other waterborne materials. Drift material may be deposited at or near the high water line in ponded or flooded areas, piled against the upstream sides of trees, rocks, and other fixed objects, or widely distributed within the dewatered area.

Drift Deposits (B3)

Presence of a layer of any thickness containing 2 percent or more iron-oxide coatings or plaques on the surfaces of living roots and/or iron-oxide coatings or linings on soil pores immediately surrounding living roots within 12 inches (30 cm) of the surface.

Oxidized Rhizospheres on Living Roots (C3)

This indicator is present if the area in question is located in a localized depression, swale or drainageway, concave position within a floodplain, at the toe of a slope, on the low-elevation fringe of a pond or other water body, or in an area where groundwater discharges. This indicator does not include concave positions on rapidly permeable soils (e.g., floodplains with sand and gravel substrates) that do not have wetland hydrology unless the water table is near the surface.

Geomorphic Position (D2)

This indicator consists of a mat or dried crust of algae, perhaps mixed with other detritus, left on or near the soil surface after dewatering.

Algal Mat or Crust (B4)

Presence of a layer containing reduced (ferrous) iron in the upper 12 inches (30 cm) of the soil profile, as indicated by a ferrous iron test or by the presence of a soil that changes color upon exposure to the air.

Presence of Reduced Iron (C4)

This indicator consists of the presence of an aquitard within 24 inches (60 cm) of the soil surface that is potentially capable of perching water within 12 inches (30 cm) of the surface.

Shallow Aquitard (D3)

This indicator consists of a thin orange or yellow crust or gel of oxidized iron on the ground surface or on objects near the surface.

Iron Deposits (B5)

Presence of a layer containing 2 percent or more redox concentrations as pore linings or soft masses in the tilled surface layer of soils cultivated within the last two years. The layer containing redox concentrations must be within the tilled zone or within 12 inches (30 cm) of the soil surface, whichever is shallower.

Recent Iron Reduction in Tilled Soils (C6)

The plant community passes the FAC-neutral test.

FAC-Neutral Test (D5)

Surface soil cracks consist of shallow cracks that form when fine-grained mineral or organic sediments dry and shrink, often creating a network of cracks or small polygons.

Surface Soil Cracks (B6)

This indicator is present if individuals of the same species growing in the potential wetland are clearly of smaller stature, less vigorous, or stressed compared with individuals growing in nearby non-wetland situations.

Stunted or Stressed Plants (D1) (LRR A)

Presence of elevated ant mounds 6 in. (15 cm) or more in height built in response to seasonal flooding, ponding, or high water tables.

Raised Ant Mounds (D6) (LRR A)

One or more recent aerial photographs or satellite images show the site to be inundated.

Inundation Visible on Aerial Imagery (B7)

Other (Explain in Remarks)

This indicator consists of hummocky microtopography produced by frost action in saturated wetland soils.

Frost-Heave Hummocks (D7)

On concave land surfaces (e.g., depressions and swales), the ground surface is either unvegetated or sparsely vegetated (less than 5 percent ground cover) due to long-duration ponding during the growing season.

Sparsely Vegetated Concave Surface (B8)
