Enbridge Pipelines Inc. Alberta Clipper Project Early Summer Rare Vegetation Survey

1.0 INTRODUCTION

1.1 Project Description TERA Environmental Consultants (TERA) was commissioned by Enbridge Pipelines Inc. (Enbridge) to conduct a rare plant survey along segments of the proposed Alberta Clipper Project (Project). As part of the Project, Enbridge is proposing to construct an approximately 1,074 km long, 914 mm O.D. (NPS 36) pipeline to transport oil from Hardisty, Alberta, to the United States (US) border near Gretna, Manitoba (Figure 1).

The proposed pipeline traverses mainly privately-owned lands, some provincial Crown-owned lands and three federal Prairie Farm Rehabilitation Administration (PFRA) lands. The terrain along the proposed route is generally flat to gently rolling terrain. However, moderately steep to steep slopes are encountered at the valleys associated with some of the watercourse crossings (i.e., Eagle Creek valley [both crossings], South Saskatchewan River valley, Qu'Appelle River valley, Souris River valley, Thornhill Coulee and Deadhorse Creek valley).

Subject to regulatory approvals, construction of the pipeline portion of the Alberta Clipper Project is scheduled to begin in summer 2008.

The rare plant survey was planned to be conducted along all route segments of 100 m or larger that support native vegetation, and at all creek and river crossings. Access to a few segments was not granted during the 2007 early summer field season and, therefore, these areas have not been surveyed to date. Early season surveys were conducted between May 25 and June 15, June 27 and July 5, and July 16, 2007. Late season surveys will be conducted in July and August, 2007.

Although rare plant surveys can confirm the presence of rare plants, they cannot definitively state that rare plant species are not present on a site.

The main objectives of the surveys were to:

• identify rare plant species and rare plant communities along the proposed route as defined by the Species at Risk Act (SARA), the Committee on the Status of Endangered Wildlife in Canada (COSEWIC), the Alberta Natural Heritage Information Centre (ANHIC), the Saskatchewan Conservation Data Centre (SK CDC), or the Manitoba Conservation Data Centre (MB CDC);

• provide mitigation recommendations in the event that rare plants or rare plant communities are observed; and

• record plant communities along the proposed pipeline route (maintained in field notes, not published in this report).

1.2 Ecosystem Classification The proposed pipeline route traverses the Aspen Parkland, Mixed Grassland, Moist Mixed Grassland, Boreal Transition and Lake Manitoba Plain ecoregions (Environment Canada 2006a). However, most of the lands along the route have been broken or cleared for agricultural purposes. Remnant native vegetation along the route is primarily located on soils unsuitable for farming or where topographic constraints would restrict farming practices. Remnant native vegetation ranges from fescue grasslands to trembling aspen and/or bur oak forests. The ecoregions encountered along the proposed Alberta Clipper pipeline route are identified in Table 1.

The Aspen Parkland Ecoregion extends in a broad arc from southwestern Manitoba, north and west through Saskatchewan to its northernmost point in central Alberta. This ecoregion is a transitional area between the boreal forest to the north and the grasslands to the south. Most of the ecoregion is now farmland. In its native state, the landscape was characterized by trembling aspen, oak groves, mixed tall shrubs and intermittent fescue grasslands. Open stands of trembling aspen and shrubs occur on most sites, and bur oak and grassland communities occupy increasingly drier sites on loamy Black Chernozemic soils. Poorly-drained, Gleysolic soils support willow and sedge species (Environment Canada 2006a).

The Central Parkland Natural Subregion is located in central Alberta between the cooler, moister boreal subregions to the north and the warm, dry grassland subregions to the south. This subregion has been extensively cultivated; however, a mosaic of aspen and prairie communities occupies the remnant native parkland areas (Natural Regions Committee 2006). The proposed pipeline route traverses the southeastern portion of the subregion which is characterized by grasslands dominated by plains rough fescue with aspen stands restricted to moist sites. Although generally dominated by plains rough fescue, western porcupine grass, northern wheatgrass, slender wheatgrass and Hooker's oatgrass may make up a large component of the community depending on the amount of grazing. An assortment of forbs may also occur in variable quantity depending on the soil moisture (Natural Regions Committee 2006).

September 2007 4462 Page 3

Enbridge Pipelines Inc. Alberta Clipper Project Early Summer Rare Vegetation Survey

The Northern Fescue Natural Subregion is climatically very similar to the Central Parkland Subregion. This subregion has been largely cultivated, however, unlike the Central Parkland Subregion approximately 40% of the subregion is native prairie utilized for grazing. Plains rough fescue dominated grasslands on hummocky to rolling hills characterize this subregion. Aspen stands within the Northern Fescue Natural Subregion are much less common even on moist sites than in the Central Parkland Ecoregion (Natural Regions Committee 2006).

The Mixed Grassland Ecoregion in southwestern Saskatchewan and southeastern Alberta forms part of the shortgrass prairie in the Great Plains of North America. The natural vegetative cover is dominated by spear grass, blue grama grass and wheatgrass. June grass and dryland sedge are principal associates. Blue grama and spear grass predominate on drier sites, along with dwarf sedges. A variety of shrubs and herbs also occur, with sagebrush being the most abundant. Yellow cactus and prickly pear are often present on the driest sites. Scrubby aspen, willow, cottonwood and box-elder occur to a limited extent on shaded slopes of valleys and river terraces. Local saline areas support alkali grass, wild barley, greasewood, red sampire and sea blite (Environment Canada 2006a).

The Moist Mixed Grassland Ecoregion comprises the northern extension of open grasslands in the Interior Plains of Canada and is closely correlated with semiarid moisture conditions and Dark Brown Chernozemic soils. Native vegetation is relegated to nonarable pasture lands dominated by spear grass and wheatgrass, and a variety of deciduous shrubs including buckbrush, chokecherry, wolf willow and saskatoon. Patches of scrubby aspen, willow, cottonwood and box-elder occur to a limited extent on shaded slopes of valleys, on river terraces, and ringing nonsaline depressional sites covered with meadow grasses and sedges. Local saline soil areas support alkali grass, wild barley, red sampire and sea blite (Environment Canada 2006a).

The Boreal Transition Ecoregion, also referred to as the Southwest Manitoba Uplands, is comprised of two elevated uplands, the more southerly Turtle Mountain area and the Pembina Hills which are traversed by the proposed route. The Boreal Transition Ecoregion is characterized by closed trembling aspen forests with lesser amounts of balsam poplar, an understory of tall shrubs and a ground cover of mixed herbs. White spruce and balsam fir are the climax species; however, they are not well represented. Poorly-drained sites are usually covered with sedges, willow and some black spruce and tamarack. The dominant soils in this area are well to imperfectly-drained Dark Gray Chernozems (Environment Canada 2006a).

The Lake Manitoba Plain Ecoregion is transitional between areas of boreal forest to the north and the aspen parkland of the southwest. It is a mosaic of trembling aspen/oak groves and rough fescue grasslands. Trembling aspen and shrubs occur on moist sites, and bur oak and grass species occupy increasingly drier sites on loamy to clayey, Black Chernozemic soils. Poorly-drained, Gleysolic soils support willow and sedge communities (Environment Canada 2006a).

2.0 METHODS

2.1 Literature Review Prior to the field assessment, a literature review was conducted to identify rare plant species and plant communities with potential to occur in the area of the proposed pipeline route. Reports from the previous Enbridge Capacity Expansion Program (CEP) and Terrace Phases I and II pipeline projects were reviewed to determine any known rare plant/community locations along the existing pipeline corridor (Wild Rose Consulting 1998a,b,c, Enbridge 1999, TERA 1995, 1999, 2000, 2001, 2002, 2003, 2004). Tables of potential rare vascular plant species, and rare plant communities that occur in the ecoregions crossed by the proposed pipeline were produced using data available from ANHIC, the SK CDC and the MB CDC, and are included as Appendices A and B. Definitions of rarity ranks and classes are included in the footnotes of these Appendices.

The ANHIC vascular plant tracking list and watch list data by Natural Subregion (ANHIC 2002a) is made available upon request, and the latest edition was provided in 2005 (ANHIC 2005). The SK CDC and the MB CDC provides tables of rare species and plant communities by ecoregion (Saskatchewan Environment (SENV) 2007a, MB CDC 2006a). Habitats were added by TERA using a variety of resources, as referenced in the footnotes of Appendix A.

All potential vascular plant tables were modified to include whether the range of the plant was in the vicinity of the site and whether the habitat of the plant was in the vicinity of the site. In Alberta, the range was based on the distribution maps in Kershaw et al. 2001 and Moss 1983. In Saskatchewan, the range was based on the distribution maps in The Rare and Endangered Native Vascular Plants of Saskatchewan (Harms et al. 1992). In Manitoba, the range was based on the distribution maps in The Rare Vascular Plants of Manitoba and the published volumes of the Flora of North America (FNA) (White and Johnson 1980, Flora of North America Editorial Committee 1993+). Habitat decisions were made prior to field work, based upon the habitat types visible on the aerial photography and from experience gained during previous rare plant surveys along the pipeline route. Updated species tables with ground- truth habitat decisions will be included in the final 2007 rare plant survey report, once the late summer survey has been completed. All plant community tables were modified to include whether the range of the community was in the vicinity of the site.

ANHIC, the SK CDC and the MB CDC also provided records of 34 known rare plant species occurring within 1 km of the proposed Alberta Clipper pipeline route (Appendix C). The SK CDC and the MB CDC reported no records of rare plant communities traversed by the proposed pipeline route in Saskatchewan and Manitoba. However, there are records of one Environmentally Significant Area and one Consultative Notation (CNT) traversed by the proposed route in Alberta.

The Sounding-Sunken Environmentally Significant Area is an area of National importance, and is traversed from KP 217.4 to KP 230.9 (Alberta Community Development (ACD) 2001). The Sounding-Sunken Environmentally Significant Area includes the Cluster of Unnamed Lakes (Hughenden), Sounding Lake, Sounding Dunes and Metiskow Lake. The Sounding-Sunken area offers the only known location for round-leaf monkeyflower (Mimulus glabratus) in Alberta. The area is also characterized by the diversity of vegetation communities, which include rough fescue-porcupine grass interspersed with aspen groves (Alberta Environmental Protection [AEP] 1997).

A Consultative Notation (CNT) for a rare native species revegetation study enclosure site exists at KP 196.7 to KP 197.8 (CNT 990025) (Alberta Energy 2007). The enclosure site is a long-term monitoring project managed by Alberta Sustainable Resource Development (Porter pers. comm.).

Prior to field data collection, air photographs were consulted in order to identify areas of high potential habitat for rare plant species (e.g., seepage areas, riparian areas, under-represented ecosystems).

2.2 Data Collection Rare plant surveys were conducted in accordance with the rare plant survey guidelines as created by the Alberta Native Plant Council (ANPC) (2000). A rare plant specialist surveyed segments of the proposed Alberta Clipper pipeline route that encounter native vegetation, noted the dominant plant communities occurring along the route and searched for rare plants. A meander walking technique was used to survey the 40 m wide proposed construction right-of-way and extra work space for rare plant species. At locations where potentially important microsites were observed, more detailed searches were performed. Species nomenclature is according to the ANHIC (2002b) complete element list with more current taxonomic information drawn from NatureServe (2007) when necessary.

In the event that a rare plant species is observed, a thorough search is conducted to determine the extent of the population. The population is mapped, a GPS location is recorded, photographs are taken and a detailed plant source feature/element occurrence field form is completed and submitted to the relevant provincial authority (i.e., ANHIC, the SK CDC or the MB CDC). Voucher specimens of rare plant species are collected following the 1:25 guideline put forth by the ANPC (i.e., one specimen can be collected for every 25 observed). However, due to the importance of voucher specimens to the verification of rare plant observations, specimens may be collected under certain circumstances at the lower population numbers (i.e., one specimen may be collected for every 20 observed) suggested in the ANPC rare plant survey guidelines (ANPC 2000). Circumstances under which specimens may be collected from smaller populations include encountering a species that is difficult to identify by photograph alone, or instances when collection is not likely to adversely impact the continued reproductive success of the population, such as when numerous flowering individuals are encountered. Any plant species requiring verification is confirmed at a qualified herbarium for the region.

In the event that a rare plant community is observed, the community is mapped or marked on an air photo and a GPS location is recorded. A description of the site and vegetation is documented on forms. A species list for a representative plot of the appropriate size (20 m2 for forested, 10 m2 for shrub dominated and 5 m2 for grasslands) is recorded and percent cover for each species is estimated.

2.3 Survey Locations The segments of the route that were surveyed for rare plants are listed in Appendix D and shown in Figure D-1.

3.0 RESULTS

3.1 Alberta

3.1.1 Potential Species at Risk Of the potential rare plant and rare plant communities identified for the Alberta segment of the route (Appendcies A, B and C), there are no SARA-listed or COSEWIC-listed species that have potential to occur in the ecoregions traversed by the proposed Alberta Clipper pipeline route.

No species at risk were observed during the survey.

3.1.2 Previous Rare Species and Community Observations During the rare plant surveys for the previous Enbridge CEP and Terrace Phase II pipeline projects, six rare plant species were observed (Table 2). Sand millet (Panicum wilcoxianum), Schweinitz's flatsedge (Cyperus schweinitzii) and little bluestem (Schizachyrium scoparium var. scoparium) were observed in areas traversed by the proposed route. American water-horehound (Lycopus americanus), bur oak (Quercus macrocarpa) and large Canada St. John's wort (Hypericum majus) were observed in the vicinity of the proposed route.

3.1.3 Rare Plants A list of all species observed in Alberta during the early summer survey is included in Table G-1 of Appendix G.

During the early summer rare survey of the selected Alberta segments of the proposed Alberta Clipper pipeline, one ANHIC listed rare plant species, pale blue-eyed grass (Sisyrinchium septentrionale) (S2S3), was observed. The location of these rare plant sightings is summarized in Table 3 and shown in Appendix E.

3.1.3.1 Pale Blue-Eyed Grass (Sisyrinchium septentrionale) (S2S3) Pale blue-eyed grass (Sisyrinchium septentrionale Bicknell) is a slender, tufted perennial herb that grows 10-20 cm tall. Leaves are grass-like and occur basally. Flowers range from pale violetblue to almost white and occur in small clusters within the axils of the bracts. Pale blue-eyed grass can be found in moist meadows and grassy streambanks (Kershaw et al. 2001).

Pale blue-eyed grass was observed at one location along the proposed route in Alberta at KP 272.3, in SE 35-37-1 W4M. Approximately 100 plants were observed in a 30 x 60 m area in a moderately grazed native prairie pasture on the proposed right-of-way. The plants were observed along a shallow draw, which drains into Eyehill Creek, immediately north of the proposed disturbance area (Plate F-1).

3.1.4 Rare Plant Communities None of the ANHIC-listed rare plant communities were observed along surveyed segments of the proposed Alberta Clipper pipeline route in Alberta.

3.2 Saskatchewan

3.2.1 Potential Species at Risk Potential rare plant and rare plant communities along the Saskatchewan segments of the proposed route are identified in Appendices A, B and C. Of these, the following six SARA-listed plants that have potential to occur in the ecoregions traversed by the proposed Alberta Clipper pipeline route: buffalo grass (Buchloë dactyloides), hairy prairie-clover (Dalea villosa var. villosa), slender mouse-ear cress (Halimolobos virgata), small cryptanthe (Cryptantha minima), small-flowered sand-verbena (Tripterocalyx micranthus) and western spiderwort (Tradescantia occidentalis). Three of these six species have known ranges in the vicinity of the proposed route: buffalo grass, hairy prairie clover and slender mouse-ear cress.

In addition, there are two COSEWIC-listed species which have potential to occur in the ecoregions traversed by the proposed pipeline route (COSEWIC 2007). These are smooth goosefoot (Chenopodium subglabrum) and tall woolly-heads, prairie population (Psilocarphus brevissimus).

None of these species at risk were observed during the survey.

3.2.2 Previous Rare Species and Community Observations During the rare plant surveys for the previous Enbridge CEP and Terrace pipeline projects, 16 rare plant species were observed (Table 4). Seven of the observed species were located in areas traversed by the proposed route (narrow-leaved plantain, few-flowered aster, awned/mountain mousetail, least mousetail, smooth arid goosefoot, crowfoot violet and eastern yellow stargrass). The other rare plant species were observed in the vicinity of the proposed route.

Annual lupine was observed at one location along the proposed route at KP 506.1, in NE 31-27-7 W3M in a native prairie pasture on the east slope of the South Saskatchewan River valley. Thirty-nine plants were observed in a 42 x 65 m area on the proposed right-of-way and extending south of the right-of-way (Plate F-2).

3.2.3.2 Bracted Bog Orchid (Coeloglossum viride var. virescens) (S3S4) Bracted bog orchid (Coeloglossum viride var. virescens [Muhlenberg] Luer) is a perennial herb that ranges from 6-80 cm tall. Flowers occur in a spike-like arrangement and are green often with dull red or brown speckles. Large conspicuous bracts occur between the flowers. This plant grows in a wide variety of habitats that includes moist to wet coniferous and hardwood forests, tundra, prairies, meadows, thickets, coastal heaths and bogs (Flora of North America 1993+).

Bracted bog orchid was observed at the following five locations in native bush pasture along the proposed route in Saskatchewan: KP 879.4 in NE 31-12-2 W2M; at KP 895.6 in NW 11-12-1 W2M; at KP 896.2 in NE 11-12-1 W2M; at KP 896.4 in NE 11-12-1 W2M; and at KP 898.8 in SE 12-12-1 W2M and S1/2 1-12-34 WPM.

At KP 879.4, seven plants were observed 4 m southwest of the proposed pipeline right-of-way. At KP 895.6, twelve plants were observed in a 7 x 3 m area, with one outlying plant, all located 9 m south of the proposed right-of-way (Plate F-3). At KP 896.2, twelve plants were observed along a cow trail on the southern-most edge of the proposed right-of-way, entirely within the proposed disturbance area (Plate F-4). At KP 896.4, seven plants were observed in a 3 x 2 m area on the southern-most edge of the proposed right-of-way, entirely within the proposed disturbance area (Plate F-5). At KP 898.8, eight plants were observed for a 25 m length paralleling the proposed route, 10 m south of the proposed right-of-way (Plate F-6).

3.2.3.3 Bristly Mousetail (Myosurus apetalus var. borealis) (S2?) Bristly mousetail (Myosurus apetalus var. borealis Whittemore) is a small annual herb (Moss 1983) with a grass-like appearance. Flowers have sepals (petal-like structures) that are 1-veined with broad dry translucent edges. Seeds of this species are borne in heads that can be narrowly elliptic or rectangular and range from 4-9 mm long. This plant is found in flats and marshes and often associated with sagebrush (Flora of North America 1993+).

Bristly mousetail was observed at the following two locations along the proposed route in Saskatchewan: at KP 425.6 in SE 33-30-15 W3M; and at KP 576.0 in SW 6-24-1 W3M. At KP 425.6, thousands of plants were observed in a 40 x 25 m area, 300 m northwest of Eagle Creek, with approximately 60% of the population on the proposed right-of-way (Plate F-7). At KP 576.0, thousands of plants were observed in a 45 x 35 m area in native prairie pasture, on the south side of the proposed right-of-way, with approximately 80% of the population occurring on the proposed disturbance area (Plate F-8).

3.2.3.4 Common Beggarticks (Bidens frondosa) (S2S3) Common beggarticks (Bidens frondosa L.) is an annual herb with stems 30-150 cm tall. Leaves are opposite and pinnately divided. Flowers are most commonly orange but may be pale yellow and do not have the characteristic long outer petals commonly associated with the aster family. Seeds are tipped with two stiff awns (bristles). This plant prefers moist ground and ditches, and occasionally dry waste areas (Kershaw et al. 2001).

Common beggarticks was observed at one location along the proposed route in Saskatchewan at KP 878.2 in NW 31-12-2 W2M in native bush pasture. Approximately 400-500 plants were observed in a watering hole with a diameter of approximately 25-30 m, located 6 m southwest of the proposed pipeline right-of-way (Plate F-9).

3.2.3.5 Field Grape Fern (Botrychium campestre) (S1) Field grape fern (Botrychium campestre W.H. Wagner & D.R. Farrar) is a small fleshy perennial herb that grows 6-12 cm tall. It has two leaf types, a single sterile leaf blade below a single fertile leaf. Both blades are pinnately divided and the spore clusters that form on the fertile leaf blade are small, spherical, yellow and stalkless. This species prefers grassy fields and ditches (Kershaw et al. 2001).

Field grape fern was observed at the following two locations along the proposed route in Saskatchewan: at KP 506.1 in NE 31-27-7 W3M; and at KP 871.4 in NW 4-13-3 W2M. At KP 506.1, 24 plants were observed entirely within the proposed disturbance area (Plate F-10). The plants were located along the east slope of the South Saskatchewan River valley in native prairie pasture, 13-35 m south of a sand trail paralleling the northern edge of the proposed right-of-way. At KP 871.4, ten plants were observed on the south side of the proposed right-of-way, within native prairie pasture 50 m west of Montgomery Creek (Plate F-11). Nine plants were observed within a 2 x 3 m area on the proposed disturbance area and one outlying plant was observed south of the disturbance area, off the proposed right-of-way.

3.2.3.6 Pale Blue-Eyed Grass (Sisyrinchium septentrionale) (SNR) Pale blue-eyed grass (Sisyrinchium septentrionale Bicknell) is a slender, tufted perennial herb that grows 10-20 cm tall. Leaves are grass-like and occur basally. Flowers range from pale violetblue to almost white and occur in small clusters within the axils of the bracts. Pale blue-eyed grass can be found in moist meadows and grassy streambanks (Kershaw et al. 2001).

Pale blue-eyed grass was observed at one location along the proposed route in Saskatchewan at KP 324.6 in NE 9-35-24 W3M. Within an approximately 10 x 10 m area, north of the proposed right-of-way, 27 plants were observed in a native grassland previously disturbed by existing pipeline rights-of-way (Plate F-12).

3.2.4 Rare Plant Communities None of the SK CDC-listed rare plant communities were observed along the surveyed segments of the proposed Alberta Clipper pipeline route in Saskatchewan.

3.3 Manitoba The early summer rare plant survey for the segment of the Alberta Clipper project from Cromer, Manitoba to the U.S. border near Gretna, Manitoba (KP 960.0 to KP 1245.2) was conducted in conjunction with the early summer rare plant survey for the LSr pipeline of the Enbridge Southern Lights Project. The results of the early summer rare plant survey of the LSr pipeline have previously been submitted to the National Energy Board. The following subsections describe the results along the portion of the Alberta Clipper pipeline route in Manitoba from the Saskatchewan border to Cromer, Manitoba (KP 960.0).

3.3.1 Potential Species at Risk Potential rare plant and rare plant communities along the Saskatchewan segments of the proposed route are identified in Appendices A, B and C. Of these, the following six SARA-listed plants have potential to occur in the ecoregions traversed by the proposed Alberta Clipper pipeline route: buffalo grass (Buchloë dactyloides), hairy (silky) prairie-clover (Dalea villosa var. villosa), Riddell's goldenrod (Solidago riddellii), small white lady's-slipper (Cypripedium candidum), western silvery aster (Symphyotrichum sericeum (Aster sericeus) and western spiderwort (Tradescantia occidentalis). Three of these six species have known ranges in the vicinity of the proposed route: hairy prairie clover; western spiderwort; and small white lady's slipper.

In addition, there are two COSEWIC-listed species which have the potential to occur in the ecoregions traversed by the proposed pipeline route (COSEWIC 2007). These are rough agalinis (Agalinis aspera) and smooth goosefoot (Chenopodium subglabrum). The Manitoba Endangered Species Act also lists Culver's-root (Veronicastrum virginicum) as Threatened, which has the potential to occur in ecoregions traversed by the proposed route.

September 2007 4462 Page 17

Enbridge Pipelines Inc. Alberta Clipper Project Early Summer Rare Vegetation Survey

The only species at risk observed during the early summer survey was small white lady's-slipper (Cypripedium candidum), which was found at KP 948.9, in SW 4-20-2 WPM (see Section 3.3.3.4 and Table 8). The individuals observed were not in flower at the time of the survey and, therefore, could not be confirmed. Consequently, the location will be re-visited in early spring 2008 for confirmation.

3.3.2 Previous Rare Species and Community Observations No rare plant species were observed along the Alberta Clipper pipeline route from the Saskatchewan border and Cromer, Manitoba (KP 945.0 to KP 960.0) during the rare plant surveys for Enbridge Terrace Phase I (TERA 2001).

3.3.3 Rare Plants A list of all identifiable species observed during the early summer survey is included in Table G-3 of Appendix G.

During the early summer rare plant survey of the selected segments of the proposed Alberta Clipper pipeline from the Saskatchewan border to Cromer, Manitoba (KP 960.0), three MB CDC listed rare plant species were observed. The rare plants observed were:

golden bean (Thermopsis rhombifolia) (S2);

narrowleaf milk vetch (Astragalus pectinatus) (S2S3); and

small white lady's-slipper (Cypripedium candidum) (S1) (to be confirmed).

The locations of these rare plant sightings are summarized in Table 6 and shown in Appendix E.

3.3.3.1 Golden Bean (Thermopsis rhombifolia) (S2) Golden bean (Thermopsis rhombifolia [Nutt.] Richards.) is a perennial herb that grows 10-40 cm tall in dry, sandy grassland, and has leaves with three leaflets. It has yellow, pea-like flowers, and flat pods that are 4-7 cm long and curve into a sickle shape as they mature (Moss 1983).

Golden bean was observed at the following two locations along the proposed route from the Saskatchewan border to Cromer, Manitoba - at KP 951.3 in NW and NE 34-9-29 WPM; and at KP 955.5 in SE 25-9-29 WPM. At KP 951.3, more than 120 plants were observed in an approximately 1 ha area on the south side of the proposed right-of-way, on and off the proposed disturbance area (Plate F-13). Golden bean was common in the immediate area around KP 951.3. More than 300 plants were observed in a 25 x 14 m area with narrowleaf milk vetch, on the proposed right-of-way and extending south into the surrounding area (Plate F-14).

3.3.3.2 Narrowleaf Milk Vetch (Astragalus pectinatus) (S2S3) Narrow-leaved milk vetch (Astragalus pectinatus Dougl. ex Hook.) is a perennial herb that grows approximately 2-6 dm high. Leaflets are narrow and linear and number 9-17. Flowers are yellowish-white, approximately 2 cm long, and are borne in conspicuous racemes (loose spike-like arrangement). Pods are oblong to elliptical and become hard and reflexed when mature. This species prefers prairie habitat with alkaline soil (Moss 1983).

Narrowleaf milk vetch was observed at one location along the proposed route in Manitoba at KP 955.5, in SE 25-9-29 WPM. Four plants were observed in a 25 x 14 m area with golden bean, on the proposed right-of-way and extending south into the surrounding area (Plate F-14).

3.3.3.3 Small White Lady's-Slipper (Cypripedium candidum) (S1) Small white lady's-slipper is a perennial that grows from a single rhizome and forms large clumps. It is found in prairie openings, wooded grasslands and marshy areas. It prefers calcareous sandy loam soil and a southerly aspect. It flowers from late May to early June, and may take years to flower.

A clump of approximately ten individuals of what is suspected to be small white lady's-slipper were identified during the early summer survey at KP 948.9 in SW 4-20-29 WPM. They were located in a road ditch within the right-of-way adjacent to Road 54N (Plate F-15). The individuals observed were not in flower at the time of the survey and, therefore, could not be confirmed. Therefore, the location will be re-visited in early spring 2008 to for confirmation.

3.3.4 Rare Plant Communities None of the MB CDC-listed rare plant communities were observed along surveyed segments of the proposed Alberta Clipper pipeline route from the Saskatchewan border to Cromer, Manitoba (KP 960.0).

Provincial (S) ranks are based solely on the species' status within the province, and range from 1 (5 or fewer occurrences) to 5 (demonstrably secure under present conditions) (NatureServe 2007). S1 = Critically Imperilled: because of extreme rarity or because of some factor(s) making it especially vulnerable to extirpation. Typically 5 or fewer occurrences or very few remaining individuals (<1,000). S2 = Imperilled: because of rarity or because of some factor(s) making it very vulnerable to extirpation. Typically 6-20 occurrences or few remaining individuals (1,000-3,000). S3 = Vulnerable: because rare and uncommon, or found in a restricted range (even if abundant at some locations), or because of other factors making it vulnerable to extirpation. Typically 21-100 occurrences or between 3,000 and 10,000 individuals. S4 = Apparently Secure: uncommon but not rare, and usually widespread in the province. Possible cause of long-term concern. Usually more than 100 occurrences and more than 10,000 individuals. S5 = Secure: common, widespread, and abundant in the province. Essentially ineradicable under present conditions. Typically with considerably more than 100 occurrences and more than 10,000 individuals. S#S# = Range Rank: a numeric range rank (e.g., S2S3) is used to indicate the range of uncertainty about the exact status of the element. SH = Historical occurrence; usually not verified in the last 20 years, but with some expectation that it may be rediscovered. SU = Unrankable: currently unrankable due to lack of information or due to substantially conflicting information about status or trends. ? = Inexact numeric rank: denotes inexact numeric rank. Q = Questionable taxonomy: taxonomic status is questionable; numeric rank may change with taxonomy. T = Designates a rank associated with a subspecies. NR = Unranked: rank not yet assessed. 2. Global (G) ranks are based on species status world-wide and follow a system parallel to that for Provincial Ranks (Note 1), ranging from 1 (5 or fewer occurrences) to 5 (demonstrably secure under present conditions). Only Global Ranks of concern (G1 to G3) or questionable ranks are displayed (NatureServe 2007). 3. N/A - Indicates that range information for this species or subspecies/variety in this province, is not available. 4. There are no Schedule 1 SARA species listed for this ecoregion.

Provincial (S) ranks are based solely on the species' status within the province, and range from 1 (5 or fewer occurrences) to 5 (demonstrably secure under present conditions) (NatureServe 2007). S1 = Critically Imperilled: because of extreme rarity or because of some factor(s) making it especially vulnerable to extirpation. Typically 5 or fewer occurrences or very few remaining individuals (<1,000). S2 = Imperilled: because of rarity or because of some factor(s) making it very vulnerable to extirpation. Typically 6-20 occurrences or few remaining individuals (1,000-3,000). S3 = Vulnerable: because rare and uncommon, or found in a restricted range (even if abundant at some locations), or because of other factors making it vulnerable to extirpation. Typically 21-100 occurrences or between 3,000 and 10,000 individuals. S4 = Apparently Secure: uncommon but not rare, and usually widespread in the province. Possible cause of long-term concern. Usually more than 100 occurrences and more than 10,000 individuals. S5 = Secure: common, widespread, and abundant in the province. Essentially ineradicable under present conditions. Typically with considerably more than 100 occurrences and more than 10,000 individuals. S#S# = Range Rank: a numeric range rank (e.g., S2S3) is used to indicate the range of uncertainty about the exact status of the element. SH = Historical occurrence; usually not verified in the last 20 years, but with some expectation that it may be rediscovered. SU = Unrankable: currently unrankable due to lack of information or due to substantially conflicting information about status or trends. ? = Inexact numeric rank: denotes inexact numeric rank. Q = Questionable taxonomy: taxonomic status is questionable; numeric rank may change with taxonomy. T = Designates a rank associated with a subspecies. NR = Unranked: rank not yet assessed. 2. Global (G) ranks are based on species status world-wide and follow a system parallel to that for Provincial Ranks (Note 1), ranging from 1 (5 or fewer occurrences) to 5 (demonstrably secure under present conditions). Only Global Ranks of concern (G1 to G3) or questionable ranks are displayed (NatureServe 2007). 3. COSEWIC (2007). Species listed as 'Extirpated', 'Not at Risk' or 'Data Deficient' were generally not included in the table without other noteworthy factors being present. Threatened: A species likely to become endangered if limiting factors are not reversed. 4. SARA. The Act establishes Schedule 1 as the list of species to be protected on all federal lands in Canada. Threatened: a species that is likely to become an endangered species if nothing is done to reverse the factors leading to its extirpation or extinction. 5. Saskatchewan Wildlife Act, A species legislated as endangered or threatened under the Saskatchewan Wildlife Act as designated by the ESAC using definitions based on those used by COSEWIC in Canada (see Note 3). 6. N/A - Indicates that range information for this species or subspecies/variety in this province, is not available.

Ratings that are not of concern (4-5) are not included. ? = Element is not yet ranked (i.e., S?), or has an inexact numerical rank (e.g., S1?) U = Unrankable: currently unrankable due to lack of information or due to substantially conflicting information about status or trends.

Provincial (S) ranks are based solely on the species' status within the province, and range from 1 (5 or fewer occurrences) to 5 (demonstrably secure under present conditions) (NatureServe 2007). S1 = Critically Imperilled: because of extreme rarity or because of some factor(s) making it especially vulnerable to extirpation. Typically 5 or fewer occurrences or very few remaining individuals (<1,000). S2 = Imperilled: because of rarity or because of some factor(s) making it very vulnerable to extirpation. Typically 6-20 occurrences or few remaining individuals (1,000-3,000). S3 = Vulnerable: because rare and uncommon, or found in a restricted range (even if abundant at some locations), or because of other factors making it vulnerable to extirpation. Typically 21-100 occurrences or between 3,000 and 10,000 individuals. S4 = Apparently Secure: uncommon but not rare, and usually widespread in the province. Possible cause of long-term concern. Usually more than 100 occurrences and more than 10,000 individuals. S5 = Secure: common, widespread, and abundant in the province. Essentially ineradicable under present conditions. Typically with considerably more than 100 occurrences and more than 10,000 individuals. S#S# = Range Rank: a numeric range rank (e.g., S2S3) is used to indicate the range of uncertainty about the exact status of the element. ? = Inexact numeric rank: denotes inexact numeric rank. 2. Global (G) ranks are based on species status world-wide and follow a system parallel to that for Provincial Ranks (Note 1), ranging from 1 (5 or fewer occurrences) to 5 (demonstrably secure under present conditions). For legibility, ranks G4-G5 and T4-T5 are not displayed (NatureServe 2007). NR =Unranked: rank not yet assessed 3. Community ranges are based on information from the Environmental and Socio-economic Impact Assessment (EA) for Terrace Phase I (TERA 1997). N/A indicates that this information was not available in the Terrace Phase I EA report.
