Characteristics of Soils in the LSA


11A.2-1

This section provides a brief description of the pertinent characteristics and important comments for the 12 soil series located within the LSA. The tables within each series description present a typical site and profile description and are ordered according to soil classification with Brunisols described first, then Luvisols, Gleysols and Organic soils. The descriptions are based on field data collected during 2009. Additional tables portray the chemical characteristics of each soil series.

11A.2.1 Mildred Series

The Mildred (MIL) soil series occurs on glaciofluvial materials and is generally composed of Eluviated Dystric Brunisols. The glaciofluvial material also often occurs as a thin veneer over till (MILxt). Other common subgroups include Gleyed Eluviated Dystric Brunisols or Orthic Dystric Brunisols. The gleyed variants result from high water tables during spring runoff. The Mildred series is similar to the Firebag series with the main difference being coarse fragment content, with Mildred soils having coarse fragment content less than 20%.

Mildred soils have low water holding capacities (rapid drainage) due to their coarse texture. Water and wind erosion risk is generally low, but can increase to high on slopes of nine percent or greater (Pedocan Land Evaluation Ltd. 1993). These soils were found mainly in the southeast corner of the LSA. Mildred soils support a range of vegetation communities but are dominted by pine forests. They are commonly associated with a, b and c ecosite phases.

11A.2.2 Firebag Series

Firebag (FIR) soils are generally Eluviated Dystric Brunisols occurring on well to rapidly drained glaciofluvial materials. The glaciofluvial parent material may occur as a veneer over till (FIRxt). Other potential subgroups include Gleyed Eluviated Dystric Brunisols and Orthic Dystric Brunisols. Gleyed units often result from high water tables associated with spring runoff.

The coarse texture and high coarse fragment content (greater than 20% volume) of Firebag soils results in droughty soils with a low water holding capacity and poor nutrient regime. Wind erosion risk is generally low. Water erosion risk is generally moderate, but may increase to high on slopes greater than nine percent (Pedocan Land Evaluation Ltd. 1993). Firebag soils occur in association with Gleyed Eluviated Dystric Brunisols (Gleyed Firebag), shallow Firebag (Firebag-xt) and Gleysols (Bitumount). These soils are located mainly in the central and southeast corner of the LSA, south of the Hangingstone River. Firebag soils support a range of vegetation communities from aspen forest to mixed-coniferous and are commonly associated with a, b, and c ecosite phases.

11A.2.3 Dover Series

Dover (DOV) soils are generally Orthic Gray Luvisols developed on glaciolacustrine materials. The glaciolacustrine parent material may occur as a veneer over till (DOVxt) and be weakly calcareous and weakly saline. Water and wind erosion risk is generally low, but may increase to high on slopes greater than nine percent (Pedocan Land Evaluation Ltd. 1993). Dover soils are well drained, but occur in association with Gleyed Gray Luvisols (Gleyed Dover), and organic soils (McClelland, Albian and Hartley). These soils are located mainly in the northwest corner of the LSA, north of Hangingstone River. Dover soils support a range of vegetation communities and are commonly associated with b, c, d, e and g ecosite phases.

Fort (FRT) soils are generally Orthic Gray Luvisols, but Brunisolic Gray Luvisols were also classified and sampled as part of this series. Fort soils develop on medium textured glaciofluvial sediment overlying very coarse textured glaciofluvial sediment. Fort soils may occur in association with Mildred and Firebag series, although they are more similar to Mildred in terms of their low coarse fragment content. Water and wind erosion risk is generally low, but water erosion risk may increase to high on slopes greater than nine percent (Pedocan Land Evaluation Ltd. 1993). Fort soils occur in association with Gleyed Gray Luvisols (Gleyed Mildred) and Gleysols (Bitumount). They support mixed or mixed coniferous forest and are commonly associated with b, c, d, e and f ecosite phases.

11A.2.5 Kinosis Series

Kinosis (KNS) soils are generally Orthic Gray Luvisols but Brunisolic Gray Luvisols were also classified as inclusions in this series. Water and wind erosion risk is generally low, but water erosion risk may increase to high on slopes greater than nine percent (Pedocan Land Evaluation Ltd. 1993). Kinosis soils occur in association with Gleyed Gray Luvisols (Gleyed Kinosis), Gleysols (Steepbank), and organic soils (McClelland, Albian and Hartley). These soils are located throughout the LSA in well to moderately well drained areas. Kinosis soils generally support mixed or mixed coniferous forests and are commonly associated with b, c, d, e, and f ecosite phases.

11A.2.6 Bitumount Series

Bitumount (BMT) soils are described as Orthic Gleysols on very coarse textured glaciofluvial material. The glaciofluvial parent material may be a thin veneer over till and the xt modifier is used when till is encountered within 1 m of the surface. Within the LSA however, they are generally Rego Gleysols with peaty surface horizons. Orthic Gleysols are also found in the LSA, but are not as common as the rego variant. The water table where these soils are found is usually near the surface and these soils often experience ponding in the spring. Bitumount soils occur in association with Gleyed Eluviated Dystric Brunisols (Gleyed Firebag and Gleyed Mildred) and organic soils (McClelland, Albian and Hartley). These soils are located mainly in the central and southeast portion of the LSA, south of the Hangingstone River. Bitumount soils support a range of vegetation communities from mixed coniferous to deciduous shrub and black spruce bog forest and are commonly associated with g ecosite phases.

11A.2.7 Mamawi

Mamawi (MMW) soils are generally Rego Gleysols or Rego Humic Gleysols formed on fluvial sediments found in the bottom of fluvial channels such as the Hangingstone River and Little Horse River as well as their tributaries. Water and wind erosion risk is generally low due to their location within the landscape and the degree to which they are vegetated.

Mamawi soils occur in association with peaty Gleysols (Steepbank and Bitumount) and organic soils (Albian, Hartley or McClelland). They support a range of vegetation communities such as mixed, coniferous, and bottomland riparian forests. They are commonly associated with a wide variety of ecosite phases, ranging from d to k.

11A.2.8 Steepbank

Steepbank (STP) soils are Orthic Gleysols developed on moderately fine textured till. They may also have a peaty surface horizon. Other subgroups including Rego Gleysols (STPzr) were also identified within the LSA. The water table is usually near the surface and ponded water may occur in the spring. Steepbank soils occur in association with Gleyed Gray Luvisols (Gleyed Kinosis) and organic soils (McClelland, Albian or Hartley). These soils are located throughout the LSA in areas of imperfect or poor drainage. Steepbank soils support a range of vegetation communities including mixed forest to black spruce bog forest and are commonly associated with e, f, g, h and i ecosite phases.

11A.2.9 Hartley

The Hartley (HLY) soil series is comprised mainly of Terric Fibrisols developed on fen peat where the water table is usually at or near the surface throughout the year. Terric Fibrisols and Terric Mesic Fibrisols are found when mineral material is encountered within 160 cm of the surface. Hartley soils usually occur in association with other organic soils (Albian and McClelland) and peaty Gleysols (Steepbank, Mamawi or Bitumount) and support mainly deciduous shrub, tamarack forest and open fen communities. They are commonly associated with j and k ecosite phases.

11A.2.10 McClelland Series

The McClelland (MLD) series name is used for both Terric and Typic Mesisols. McClelland soils are generally Typic Mesisols developed from fen peat. Terric Mesisols and Terric Fibric Mesisols occur when mineral material is encountered within 160 cm of the surface. In the case of a Terric Mesisol, a modifier is assigned to the McClelland series to indicate it is Terric, rather than Typic. The modifier also varies depending on the underlying mineral texture. The modifiers, xt, xc and xs will be used for till, glaciolacustrine and glaciofluvial or fluvial, respectively.

The water table is usually at or near the surface throughout the year. McClelland soils are the most abundant series within the LSA and usually occur in association with other organic soils (Albian, Hartley) and peaty Gleysols (Steepbank, Mamawi and Bitumount) but McClelland soils can occur with almost every series occurring throughout the LSA. This includes along drainage channels where it commonly forms associations with fluvial soils (Mamawi). McClelland soils support mainly deciduous shrub, tamarack forest and open fen communities. They are commonly associated with j and k ecosite phases.
