Appendix A Soil Landscape Models


2010 Page A-3

Appendix A provides an overview of the soil landscape models derived in five physiographic regions of the project effects assessment area (PEAA):

• Southern Alberta Uplands • Alberta Plateau • Rocky Mountains • Interior Plateau • Coast Mountains

Eastern Alberta Plains was not modelled because soil inspection intensity is about one inspection per 400 m. The data sources used include the Alliance Pipeline Environmental Impact Assessment (Alliance Pipeline Limited Partnership 1997) in addition to an intensive soil field program run in 2005 and 2006.

A.1 Southern Alberta Uplands The designation of soil type by terrain combination is based on a thorough review and summation of the Wapiti and Iosegun Soil Reports (Twardy and Corns 1980; Knapik and Lindsay 1983). In this physiographic region, the following general relationships have been identified:

• Moraine: In this region, based on provincial soil surveys, the Edson till is dominant and is described as moderately fine to fine-textured and moderately calcareous. Soils developed on Edson till are dominated by Orthic Gray Luvisols and Brunisolic Gray Luvisols, with major inclusions of Gleysols and Organics in low-lying areas.

• Glaciolacustrine: Moderately fine to very fine-textured glaciolacustrine. The Donnelly soil series on glaciolacustrine in the Wapiti report is an imperfectly drained, Gleyed Solonetzic Gray Luvisol. The Donnelly series is very common in the eastern half of the Wapiti sheet. Poorly drained soils are identified as Orthic Luvic Gleysols in the Wapiti report (Twardy and Corns 1980).

• Glaciofluvial: Glaciofluvial sediments range from coarse to moderately coarse in the Wapiti map sheet. In some cases, the glaciofluvial sediments overlie either till or glaciolacustrine deposits (i.e., veneers of glaciofluvial overlying finer-textured sediments). The glaciofluvial veneers are associated with the Lodge series, which consists of Brunisolic and Orthic Gray Luvisols. The deeper glaciofluvial sediments are associated with the Blackmud series, consisting of Brunisolic Gray Luvisols and Eutric Brunisols.

• Fluvial (active and areas of inactive): A variety of materials (coarse to medium-textured materials) associated with recent fluvial activity occur in the Wapiti sheet. These sediments are associated with active fluvial stream channels. In general, Cumulic Regosols and Orthic or Humic Gleysols occur on the recent or active floodplains.

• Recent Lacustrine: Recent lacustrine materials generally are medium to very-fine textured sediments associated with the margins of lakes. Soils are dominantly Orthic and Rego-Gleysols.

• Colluvium: Colluvial sediments consist of actively eroding sediments on steep slopes where Regosolic soils have formed. Colluvial sediments associated with fans and cones are more stable and therefore Brunisols, and in some cases Luvisols, have had sufficient time to develop. Colluvial sediments are commonly mapped as “Rough Broken” in the soil reports.

Page A-4 2010

• Eolian: Veneers of wind-blown, coarse to moderately coarse sediments occur in the area. These sediments support the development of Brunisols on rapid and well-drained sites. Brunisolic Gray Luvisols are expected to occur on moderately well and imperfectly drained sites.

• Organic: Very poorly drained sites are associated with peat accumulation. Organic deposits are dominated by Mesisols with substantial amounts of Fibrisols. The depth to underlying mineral sediments is expected to vary, such that Typic and Terric subgroups will occur.

The information contained in the Wapiti and Iosegun Soil Reports (identifying soil-parent material associations) was used to develop a soil landscape model. The following matrix (see Table A-1) outlines the criteria applied in the soil landscape model applied to the PEAA in the Southern Alberta Uplands physiographic region.

A.2 Alberta Plateau The Alberta Plateau, situated along the British Columbia–Alberta boundary, contains similar topography to the western portions of the Southern Alberta Uplands physiographic region. The soil–terrain relationships in this region are based on the modelling of the Boreal White and Black Spruce (BWBS) biogeoclimatic zone as this climatic zone occupies most of the physiographic region. The common soil-terrain relationships identified in this region include:

• Colluvium: Brunisols (including Eluviated Dystric Brunisol and Eluviated Eutric Brunisol) are common on non-calcareous sedimentary rock. Eluviated Eutric Brunisols are common on calcareous sedimentary rock. Reduced leaching tends to occur on warmer aspects (e.g., southern exposures) with the development of Orthic Dystric Brunisols, Orthic Eutric Brunisols or Orthic Regosols commonly occurring.

• Fluvial (active): For most soil associations occurring in active fluvial materials, the modal classification is a Cumulic Regosol, although Orthic Regosols and associated gleyed subgroups are also common.

• Fluvial (inactive): Soil development on well or moderately well-drained fluvial deposits has resulted in the formation of Eluviated Dystric Brunisols and Brunisolic Gray Luvisols. Imperfectly drained fluvial deposits tend to develop into Gleyed Brunisolic Gray Luvisols. Poorly drained areas develop into Orthic Gleysols or Orthic Humic Gleysols.

• Glaciofluvial: In most mapped soil associations in this region, rapidly drained variants tend to be Orthic Dystric Brunisols or Orthic Eutric Brunisols. Common well-drained variants include Brunisolic Gray Luvisols, Eluviated Dystric Brunisols and Orthic Humo-Ferric Podzols, whereas moderately well-drained deposits tend to develop into Brunisolic Gray Luvisols. Imperfectly drained soils are generally Gleyed Brunisolic Gray Luvisols. Orthic Gleysols and Orthic Humic Gleysols make up most of the poorly drained glaciofluvial sediments.

• Lacustrine and Glaciolacustrine: Brunisolic Gray Luvisols are the most commonly found soil in moderately well-drained sites; Orthic Gray Luvisols or Dark Gray Luvisols may occasionally be present. Imperfectly drained soil may have Brunisolic Gray Luvisols or Orthic Gray Luvisols. Poorly drained locations tend to develop Orthic Luvic Gleysols, Orthic Gleysols or Orthic Humic Gleysols.

• Till (Morainal): Modal till soils are typically Brunisolic Gray Luvisols. In general, Orthic Gray Luvisolic and Eluviated Eutric Brunisolic soils overlie calcareous sandstone and shale whereas Eluviated Dystric Brunisols are commonly noted on non-calcareous sandstone and shale. Poorly drained soils are mainly Orthic Gleysols or Orthic Humic Gleysols.

• Organic: Organic deposits are classified as either Mesisols or Fibrisols, depending on the level of decomposition and depth of organic accumulation. Additional Organic soils were defined using a wetland classification system based on vegetation and terrain type. This classification also accounted for wet mineral soils, mineral soils with peat accumulation and Cumulic Regosols formed on floodplains (see Table A-11).

For the criteria applied in the soil landscape model applied to the PEAA in the Alberta Plateau physiographic region, see Table A-2.

A.3 Rocky Mountains A soil landscape model for this physiographic region was developed by subdividing the region into two climatic and elevation subregions. This subdivision followed the British Columbia biogeoclimatic ecological classification (BEC) of Sub-boreal Spruce (SBS) and Engelmann Spruce Subalpine Fir (ESSF) zones, which occur at different elevations and have been used to identify different soil-forming characteristics. The PEAA was divided by sub-zone and two separate model criteria were applied. The common soil–terrain relationships are outlined below.

• Colluvium: Soils developing over limestone or calcareous sedimentary bedrock are typically Eluviated Eutric Brunisols (Sheba Mountain, Suprenant and Wendt Mountain associations) with local inclusions of Orthic Humo-Ferric Podzols (Hedrick Association). The Misinchinka Association (Orthic Humo-Ferric Podzol) includes soil developed on fine-grained metamorphic parent materials. Fans, lower slopes and avalanche tracks tend to be mapped as Orthic Regosols, Sombric Ferro-Humic Podzols and gleyed subgroups.

• Weathered Bedrock: Soils developed on this parent material are likely at early stages, shown by weak horizon development. They are modelled as Eluviated Eutric Brunisols over basic bedrock and as Eluviated Dystric Brunisols over acidic bedrock. Minor inclusions of Orthic Regosols were also noted.

• Fluvial (active): The most common imperfectly drained soil occurring on fluvial material is a Gleyed Cumulic Regosol (Monkman Creek Association). Rego-Gleysols are most common on poorly drained sites. Moderately to well-drained soils are typically Cumulic Regosols, but Orthic Regosols also occur.

• Fluvial (inactive): Brunisolic Gray Luvisols and Eluviated Dystric Brunisols occur on finer-textured materials. Coarse or wet-climate variants tend to be mapped as Podzolic Gray Luvisols. Podzolic Gray Luvisols may occasionally develop on fluvial veneers over moraine.

• Glaciofluvial: Well to rapidly drained soils may develop Orthic Humo-Ferric Podzols, Eluviated Eutric Brunisols, or Eluviated Dystric Brunisols. Well to moderately well-drained soils include Brunisolic Gray Luvisols, Eluviated Dystric Brunisols, Eluviated Eutric Brunisols, with limited Orthic Humo-Ferric Podzols.

• Till (Morainal): A large variety of soils develop on till deposits. These include Brunisolic Gray Luvisols, Podzolic Gray Luvisols, Luvisolic Humo-Ferric Podzols and Orthic Humo-Ferric Podzols. Dystric and Eutric Brunisols are also found on this parent material. Orthic Regosols are often found in areas of shallow surficial material. Thin deposits of basal till over bedrock found on steep slopes (eroded or otherwise unstable) would have arrested development and would tend toward Brunisols rather than Luvisols. Poorly drained sites are generally Orthic Gleysols or Orthic Humic Gleysols.


2010 Page A-9

• Organic: Most modal organic soil associations in the literature are described as Mesisols. However, ground sites along the PEAA were generally classified as Fibrisols (Typic and Terric). At high elevation, some Terric Fibrisols are formed, which develop on sphagnum material. Some Typic Fibrisol has formed on sedge peat dominated organic parent materials. Additional Organic soils were defined using a wetland classification system based on vegetation and terrain type. This classification also accounted for wet mineral soils, mineral soils with peat accumulation and Cumulic Regosols formed on floodplains (see Table A-11). The use of this additional soil model allowed the diversity of wetland soil types to be further defined as the associated vegetation type was accounted for, which often is an indirect qualifier of water table depths and fluctuations, flooding and other soil-forming factors.

For the criteria applied in the two soil landscape models applied to the PEAA in the Rocky Mountains physiographic region, see Tables A-3 and A-4.

A.4 Interior Plateau The Interior Plateau physiographic region encompasses two biogeoclimatic zones. As in the Rocky Mountains physiographic region, the Sub-Boreal Spruce (SBS) and Engelmann Spruce Subalpine Fir (ESSF) zone are present. The soil development processes are similar; however, in many instances climatic conditions favour more advanced soil development. Common soil–terrain relationships include:

• Colluvium: Colluvial materials tend to occur on steep and unstable slopes. Where slopes have been stable for a long enough period, Brunisols dominate. The most common previously mapped Brunisolic soil associations occurring along the RoW include Orthic Dystric Brunisols, and Orthic Eutric Brunisols. The Eutric Brunisols overly basic bedrock and occur on the route along a stretch between Fort St. James and Great Beaver Lake (Dawson 1989). On less stable slopes, those with rapid mass movement or slopes over 70%, Orthic Regosols are likely to occur. Colluvial soils over acidic or unspecified bedrock are typically Orthic Humo-Ferric Podzols or Eluviated Dystric Brunisols. On herb-dominated warm aspects (south to southwest facing slopes greater than 20%), Orthic Sombric Brunisols or Orthic Melanic Brunisols are occasionally found.

• Fluvial (active): Because of frequent flooding in these areas, soil development is maintained at an early stage. The common soil series are Gleyed Regosols. Associated soil subgroups possess drainage conditions that differ from modal. Ground sites at lower elevations in the Interior Plateau are often found to have Orthic rather than Cumulic Regosols.

• Fluvial (inactive): Soil reports show that recent deposits of finer fluvial material result in Orthic Gray Luvisols. Gravelly fluvial materials, such as valley train deposits, tend to be dominated by Orthic Dystric Brunisols. Fluvial fans generally are Orthic Dystric Brunisols or Orthic Humo-Ferric Podzols.

• Glaciofluvial: West of Fort St. James, glaciofluvial soil is common on sandy and gravelly glaciofluvial valley train and pitted outwash deposits. Additional soils formed on coarse-textured glaciofluvial valley train deposits are Orthic Humo-Ferric Podzols and Eluviated Dystric Brunisols, which develop in rapidly drained conditions, and Orthic Humo-Ferric Podzol and Gleyed Orthic Humo-Ferric Podzol, which develop under well to imperfectly drained conditions. Eluviated Dystric Brunisols are common west of Fort St. James. Between Bear Lake and Great Beaver Lake are finer deposits also forming Eluviated Dystric Brunisols. Eluviated Dystric Brunisols on sandy eskers are found just south of the pipeline route and a short distance west of Bear Lake.

• Lacustrine (active): Orthic Regosols formed on existing beaches are mapped by Cotic (1974).

• Lacustrine and Glaciolacustrine (inactive): Inactive lacustrine and glaciolacustrine deposits differ from the active lacustrine as greater soil development has occurred in these soils due to time. In addition beyond the edges of glacio-lakes deposits are finer-textured soils resulting in the development of Luvisols.


2010 Page A-15

• In this model, lacustrine deposits are assumed to have similar characteristics to soil developed on glaciolacustrine deposits. Rapidly drained deposits at each edge of the large glacial lake near Fort St. James consisting of sandy pebbly form Eluviated Dystric Brunisols. Well drained deposits, and moderately well-drained deposits, are dominated by Orthic Gray Luvisols. Gleyed versions were found east of the Fort St. James airport during detailed sampling in the Agricultural Land Reserve. Lacustrine deposits along the Salmon River are also likely Orthic Gray Luvisols.

• Till (ablation): Ablation till soils for this area include Orthic Dystric Brunisols and Orthic Humo-Ferric Podzols. Ground sites uncovered less Podzolic development than had been mapped in the region (see British Columbia Soil Report 22 and 23). Soils mapped on fine-textured deposits generally were found to be Dystric Brunisols or Brunisolic Gray Luvisols in the field survey. Thin deposits of till overlying bedrock found on steep slopes (eroded or otherwise unstable) would have arrested development and tend towards Brunisols rather than Luvisols. Examples include Orthic Dystric Brunisols and Orthic Eutric Brunisols. Eroded but otherwise stable slopes can also form Orthic Gray Luvisols.

• Till (basal): Basal till tends to be very compacted below 0.3 m from the surface. Cigar-shaped hills, whether controlled by sediment (drumlins) or by bedrock (drumlinoid), are diagnostic landforms, as is the absence of pitting. Orthic Gray Luvisols form in drier climates, usually with gentle relief, whereas Brunisolic Gray Luvisols develop under wetter conditions, often with high relief or with a high degree of bedrock control. Luvisolic Humo-Ferric Podzol occur at higher elevations, usually with a high incidence of bedrock control. Ground survey sites from Dominion association landscapes found soil to be less developed Brunisolic Gray Luvisols, but these sites were at the low end of the elevation range.

• Organic: Mesic Fibrisols and Typic Fibrisols can be classified based on the presence or absence of trees, respectively. Most of the organic soils inspected were either Terric Fibrisols or Typic Fibrisol, but were further refined by the wetland model. The wetland classification model was based on vegetation and terrain type. This classification also accounted for wet mineral soils, mineral soils with peat accumulation and Cumulic Regosols formed on floodplains (see Table A-11).

For the criteria applied in the two soil landscape models applied to the PEAA in the Interior Plateau physiographic region, see Tables A-5 and A-6.

A.5 Coast Mountains The Coast Mountains physiographic region is subdivided into four biogeoclimatic (BGC) zones to accurately model the soil conditions. This region is occupied by high-relief mountainous topography, as well as coastal valley topography. These two diverse regions support substantially different climatic conditions and, therefore, soil forming processes. The Coast Mountains region includes the Coastal Western Hemlock (CWH), Mountain Hemlock (MH), Engelmann Spruce Subalpine Fir (ESSF), and Coastal Mountain Heather (CMH) BGC zones. In this physiographic region, climatic conditions vary geographically and are generally wetter and milder on the coast, grading to drier and cooler conditions across the divide toward the interior of the province (Ecological Stratification Working Group 1996). The parent materials of this region, in addition to the influences of bedrock geology and climate, have a major influence on the soil types found in the Coast Mountains. Soil types associated with each deposit can generally be categorized according to material type and thickness and soil moisture regime in each biogeoclimatic unit. The common soil–terrain relationships include:

• Colluvial: Thin to very thin colluvial parent materials generally contain Regosolic soils. Humo-Ferric Podzols and weakly developed Dystric Brunisols are commonly found on thin to thick colluvium throughout the region. Ferro-Humic Podzols constitute minor inclusions, generally developing under krummholz and dwarf evergreen scrub vegetation. Poorly to very poorly drained Gleysolic soils or gleyed and peaty variants have formed on thin to thick colluvium in lower slope positions. Folisols, composed entirely of upland (folic) materials, are commonly associated with mid to upper slopes of steep, rocky terrain that is well to imperfectly drained.

• Fluvial (active): Poorly to very poorly drained Gleysolic soils and peaty variants have formed on thin to thick fluvial materials on lower slope to depressional topographic positions with imperfect to poor drainage. Regosolics are rapidly to imperfectly drained and have formed on moderately thick to thick active fluvial deposits.

• Fluvial (inactive): Gleysolic, as well as gleyed and peaty variants of mineral soils, have developed on lower slope positions with imperfect to poor drainage. Gravelly fluvial materials tend to be dominated by Orthic Dystric Brunisols.

• Glaciofluvial: Humo-Ferric Podzols, Ferro-Humic Podzols and weakly developed Dystric Brunisols have developed on medium to thick glaciofluvial deposits. In general, glaciofluvial sediments are well drained, although localized gleyed variants of soil associations may occur.

• Glaciomarine: Humo-Ferric Podzols and weakly developed Dystric Brunisols have developed on medium to thick fine-textured glaciomarine sediments. Ferro-Humic Podzols and, to a lesser extent Dystric Brunisols, are associated with the deposition of coarse-textured (deltaic) glaciomarine sediments. Poorly to very poorly drained Gleysolic soils and peaty variants have formed on lower-slope position glaciomarine parent materials.

• Marine: Humo-Ferric Podzols and weakly developed Dystric Brunisols have developed on medium to thick marine sediments. Poorly to very poorly drained Gleysolic soils and peaty variants have formed on marine sediments in lower-slope topographic positions with imperfect to poor drainage. Imperfectly to poorly drained gleyed variants of Regosols are more commonly associated with active marine sediments.


2010 Page A-21

• Till (Morainal): Humo-Ferric Podzols and weakly developed Dystric Brunisols have developed on variable depth of till as bedrock is often near the surface in areas. Ferro-Humic Podzols constitute minor inclusions, generally developing under higher-elevation krummholz and dwarf evergreen scrub vegetation. Gleyed or gleyed and peaty variants of mineral soils have developed on lower slope and depressional topographic positions with imperfect to poor drainage. Eutric Brunisols occur infrequently, and often as gleyed subgroups on lower slopes in areas with nutrient-rich seepage or in localized riparian areas. Folisols, composed entirely of upland (folic) materials, are commonly associated with mid- to upper slopes of steep, rocky terrain that is well to imperfectly drained.

• Organic: Typic and Terric subgroups of the Fibrisol and Mesisol Great Groups are the most commonly occurring Organic soil and are found along poorly to very poorly drained margins of open wetlands, in lake or pond basins and other (localized) depressional areas in the landscape. Humisols or Humic subgroups of Mesisols also occur, but are limited in extent and typical of deep, poorly to very poorly drained sedge wetlands. Terric Mesisols, which are the most dominant Organic soils at higher elevations, are found in poorly to very poorly drained (localized) wetlands, along the margins of pond basins and depressions in the bedrock surface. Folisols were commonly found in the Coastal Western Hemlock zone and were often located over a lithic contact or fragmental rock material. These soils often supported mature forests. Additional Organic soils were defined using a wetland classification system based on vegetation and terrain type due to the diversity in the landscape from the varied topography. This classification also accounted for wet mineral soils, mineral soils with peat accumulation and Cumulic Regosols formed on floodplains (see Table A-11). The wetland vegetation varies in this area and is often bedrock controlled. This additional modelling allows the diversity of soil types to be identified by taking into account vegetation types specific to this biogeoclimatic zone which can often indicate water table depths, seepage areas and other soil forming processes.

• Weathered Bedrock: Regosolic soils are dominant in areas of exposed bedrock or very thin to thin weathered bedrock. Where soil development does occur, it is generally at an early stage, as shown by weak horizon development. These soils are modelled as Eluviated Eutric Brunisols over basic bedrock and as Eluviated Dystric Brunisols over acidic bedrock.

For the criteria applied in the two soil landscape models applied to the PEAA in the Coast Mountains physiographic region, see Tables A-7 to A-10.

Appendix B Land Capability Classification for Agriculture, Water Erosion, Wind Erosion and Compaction Ratings for Soil Types in the PEAA


2010 Page B-3

Appendix B presents the agricultural land capability classes, water erosion risk classes, wind erosion risk classes, and compaction and puddling risk classes associated with each soil type identified in the PEAA. Water erosion risks, wind erosion risks, and compaction and puddling risks are presented separately for agricultural and non-agricultural lands.

This appendix also presents a summary of the agricultural land capability class, water erosion risk, wind erosion risk, and compaction and puddling risk for each soil map unit identified in the PEAA in agricultural lands in Alberta.

B.1 Land Capability Classification for Agriculture This section presents the land capability classes and subclasses associated with dominant soil types for different slope classes on agricultural lands in Alberta and British Columbia. Soil capability for agriculture was determined according to the Canada Land Inventory (CLI) classification system in Alberta and according to a modified CLI system in British Columbia. Definitions of the CLI ratings, composed of CLI classes and subclasses, are in Section 2.7 of this report.

In British Columbia, Gleysolic and Luvisolic soil were identified in agricultural lands. Luvisols were assigned an agricultural land capability class of 5D, whereas Gleysols are rated Class 6W.

For the CLI land capability ratings for each combination of soil series and slope class identified in agricultural lands in Alberta in the PEAA, see Table B-1.
