4.2.1 Autumn Willow (S2S3) Autumn willow (Salix serissima Fern.) is a 1-5 m tall dioecious, non-colonial shrub. The branches are erect, and the twigs are yellow to red-brown and smooth. The leaves are alternate, leathery and highly glossy on their upper surface with toothed margins. The leaf-like structures at the point where the leaf stalk meets the branches, (stipules) are absent or rudimentary. Flowers occur during or after the leaf growth, and are borne in stout catkins. Autumn willow grows in wet thickets, meadows and fens in the montane zone (Douglas et al. 1998-2002) (Plate 1). Autumn willow is ranked S2S3 in BC; S4 in Alberta and G4 globally.
In addition to the three locations where autumn willow was observed in 2009, it was observed in three locations in 2010. Table 6 in Section 6.3 provides details regarding the locations and abundance of all occurrences of this species, as well as recommended mitigation measures.
4.2.2 Drummond's Thistle (S1) Drummond's thistle (Cirsium drummondii T. & G.) is a large (1.2-3 m tall) biennial herb with thick, woolly stems. The leaves are lance-shaped and deeply lobed with three to five spines along the edges of each segment (Plate 2). The leaves vary from hairless to soft-hairy on the upper surface and the lower surface of the leaves is unevenly hairy. The flowering heads are enclosed by bracts that are 3-5 cm tall with
Page 17
NOVA Gas Transmission Ltd. Supplemental Rare Plant Survey Groundbirch Mainline Project June 2010 / 6806 purplish-red disk flowers. Drummond's thistle grows in meadows, forest openings and along roadsides (Douglas et al. 1998-2002). Drummond's thistle is ranked S1 in BC, S5 in Alberta and G5 globally.
In addition to the six locations where Drummond's thistle was observed in 2009, it was observed in five locations in 2010. Table 6 in Section 6.3 provides details regarding the locations and abundance of all occurrences of this species, as well as recommended mitigation measures.
4.2.3 Hairy Buttercup (S3) Hairy buttercup (Ranunculus uncinatus D. Don) is a perennial herb growing between 30-80 cm in height with leaves divided into three lobed segments and finely toothed margins. Flowers are relatively small with petals that measure up to 3 mm long. Seeds with beaks arched into a distinct hook are dispersed from spherical heads measuring up to 4 mm in diameter. Hairy buttercup grows in moist, shaded woodlands (Moss 1983). Hairy buttercup is ranked S5 in BC, S3 in Alberta and G5 globally.
A specimen of hairy buttercup was collected from the banks of the tributary to Henderson Creek during rare plant surveys in 2009; identification was confirmed following the completion of field work. The tributary to Henderson Creek was revisited during rare plant surveys in May 2010; however, hairy buttercup could not be relocated as it was too early in the season for identification of this species. The location will be revisited again during the planned mid-summer field visit. Table 6 in Section 6.3 provides details regarding the location of this species, as well as recommended mitigation measures.
4.2.4 Pinesap (S2) Pinesap (Monotropa hypopitys L.) is a yellowish-white or pinkish plant that lacks chlorophyll and instead obtains nutrients from the roots of coniferous trees with which it shares mycorrizal fungus (Kershaw et al. 2001). Pinesap grows 10-30 cm tall, and is unbranched with scale-like leaves and a cluster of nodding to erect urn-shaped flowers (Plate 3). Capsules open by lengthwise slits releasing numerous tiny seeds. Pinesap occurs in rich, shady coniferous forests (Moss 1983). Pinesap is ranked S2 in Alberta, S3S4 in BC and G5 globally.
Pinesap was found in two patches at one location in 2010. Table 6 in Section 6.3 provides details regarding the location and abundance of this occurrence, as well as recommended mitigation measures.
4.2.5 Prairie Buttercup (S1) Prairie buttercup (Ranunculus rhomboideus Goldie) is a perennial herb, with one to several stems, that grows 10-25 cm tall. Basal leaves are long-stalked and egg to diamond-shaped, whereas stem leaves are stalkless, and divided into three to five linear segments. Flowers are yellow, with 5 petals, and grow as 3-12 per stem (Plate 4). Seeds are numerous in a globe-shaped head 4-6 mm long. Prairie buttercup grows in dry to moist open woods and grasslands (Moss 1983, Douglas et al. 1998-2001). Prairie buttercup is ranked S1 in BC, S4 in Alberta, and G5 globally.
Prairie buttercup was observed in six locations in 2010. Table 6 in Section 6.3 provides details regarding the locations and abundance of all occurrences of this species, as well as recommended mitigation measures.
4.2.6 Purple-stemmed Aster (S2S3) Purple-stemmed aster (Symphyotrichum puniceum var. puniceum) is a tufted perennial herb. It has a stiff-hairy, reddish-purple stem that grows 0.5-1.5 m tall (Plate 5). Stem leaves are 6-16 cm long with clasping ear-like flanges at their base. Flower heads have ray flowers that are blue or occasionally rose or white, with yellow disk flowers in the centre. Seeds are smooth with a tuft of white hairs. Purple-stemmed aster grows in moist streambanks and openings and is known only from northeast BC (Moss 1983, Douglas et al. 1998-2001). It is on the Red list in BC and is ranked S1. The variety is not tracked in Alberta, but the species in the general sense (synonym Aster puniceus) is ranked S4. Globally the species and variety are ranked G5T5.

In addition to the seven locations where purple-stemmed aster was observed in 2009, it was observed in two locations in 2010. Table 6 in Section 6.3 provides details regarding the locations and abundance of all occurrences of this species, as well as recommended mitigation measures.
4.2.7 Yellow-collar Moss (S2S3) Yellow-collar moss (Splachnum luteum Hedw.) is light to yellow green and grows in compact tufts 1-4 cm high. This moss has long stalks (2-15.5 cm) with yellow umbrella shaped (slightly concave) sporophytes (Plate 6). It grows on old moose dung in muskeg and other boggy woods (Crum and Anderson 1981). Yellow-collar moss is ranked S2S3 in BC, S3 in Alberta and G3 globally.
Yellow-collar moss was found in one location in 2010. Table 6 in Section 6.3 provides details regarding the location and abundance of this occurrence, as well as recommended mitigation measures.
4.3 Rare Ecological Communities One ACIMS-listed rare ecological community and one unranked community were observed along the route within Alberta, and are discussed below. No rare ecological communities as listed by the BC CDC were found during the survey.
The locations of these rare ecological community observations are mapped on Figures 2B and 2C.
4.3.1 Aspen / Thimbleberry / Wild Sarsaparilla Community (S2S3) The aspen / thimbleberry / wild sarsaparilla community (Populus tremuloides / Rubus parviflorus / Aralia nudicaulis community) is found primarily in the western part of the Central Mixedwood Natural Subregion. It is often associated with seepage areas related to a layer of reduced permeability in the soil profile that restricts drainage and channels seepage (Allen 2009). Short duration seepage likely occurs during heavy rainfall. This community is defined by an open to closed deciduous canopy clearly dominated by trembling aspen (15-40% cover), a well-developed low shrub layer with thimbleberry dominating (20-80% cover), and a high cover of wild sarsaparilla in the forb layer (Plate 7). Other species such as balsam poplar (up to 5% cover), or more infrequently, white birch may be present in the tree layer. There is a high forb cover of species indicating nutrient-rich conditions, but low cover of grasses or mosses. High-bush cranberry (up to 20% cover), prickly rose, white meadowsweet, showy aster and cream-colored vetchling are also usually present (Allen 2009). The aspen / thimbleberry / wild sarsaparilla community observed was noted by the Senior Community Ecologist at ACIMS as seeming to fit well with the rare ecological community characterization (Allen pers. comm., Allen 2009). The aspen / thimbleberry / wild sarsaparilla is ranked S2S3 in Alberta.
In addition to the three locations where this community was observed in 2009, it was observed in four locations in 2010. Table 6 in Section 6.3 provides details regarding the locations of all occurrences of this community as well as recommended mitigation measures.
4.3.2 Paper Birch / Club-moss Community (Unranked) A paper birch / club-mosses (Betula papyrifera / Lycopodium spp.) community was observed in NW 34-78-13 W6M. This community type is not currently ranked (Allen 2009) but is considered to be uncommon and is being reviewed by ACIMS (Allen pers. comm.). The community is a submesic paper birch woodland with a sparse understory comprised mainly of a number of club-moss species, with some bunchberry and mountain ash (Plate 8). The woodland is located in a midslope position within the landscape, and specifically, it occurs on a ridge crest with associated slopes of north to east aspect of variable grade (very steep to gently sloping). Soils were exposed, primarily due to recreational access, but partially due to naturally factors as well.
This community was found in one location in 2010. Table 6 in Section 6.3 provides details regarding the location and abundance of this occurrence, as well as recommended mitigation measures.

4.4 Forest Pests In Alberta, the pipeline route is located in the Mountain Pine Beetle Management Zone designated as an inactive Holding Zone (Alberta Sustainable Resource Development [ASRD] 2009). ASRD defines the Holding Zone as an area with significantly more infested trees and with larger infested patches (ASRD 2007). The primary objective for the Holding Zone is to ensure that the mountain pine beetle population remains constant from year to year. Since control is not feasible over the entire Holding Zone, some areas are identified as "inactive" areas, where the annual control targets of 50-80% of priority sites with surviving beetle broods are not applicable (ASRD 2007).
The BC portion of the route is located within the Salvage / Limited Action area within the Emergency Bark Beetle Management Area (EBBMA) for mountain pine beetles (BC Ministry of Forests and Range [MOFR] 2009). The route is also located within the Emergency Bark Beetle Management Areas for Douglas fir beetles and spruce beetles within BC (BC MOFR 2009).
In 2009, two bark beetle infestations were identified along the pipeline route, between KP 13.5 and KP 15, and west of the Kiskatinaw River near KP 60.
No new bark beetle infestations were observed during rare plant surveys in 2010. Few (<10) isolated lodgepole pine were observed, all exhibiting symptoms (i.e., reddened needles) of forest pest infestation.
Refer to the Project-specific Environmental Protection Plan (EPP) for proposed mitigation for forest pests (TERA 2010b).
4.5 Non-Native and Invasive Species Pasture areas associated with prairie buttercup and Drummond's thistle observations were commonly observed to contain low to moderate amounts of common dandelion and clover species. Furthermore, these areas are frequently characterized by a dominance of Kentucky bluegrass, smooth brome and alfalfa which are likely the result of intentional seeding. No mitigation is warranted for any of these species.
Creeping (Canada) thistle was observed in isolated locations in the vicinity of prairie buttercup and Drummond's thistle. Herbicide application used to control creeping thistle is not expected to impact the rare plant populations since they are not located adjacent to or downslope of the creeping thistle occurrences.

5.0 TRADITIONAL ECOLOGICAL KNOWLEDGE Aboriginal traditional ecological knowledge was collected in partnership between TERA and members of Doig River First Nation, Duncan's First Nation, Horse Lake First Nation, Kelly Lake Cree Nation, Kelly Lake First Nation, Kelly Lake Métis Settlement Society, McLeod Lake Indian Band, North East Métis Association of BC, Saulteau First Nations and West Moberly First Nation. Members of each community observed and assisted the spring supplemental vegetation survey. In addition, unstructured interviews were conducted in the field to discuss the role of plants and fungi for local peoples and cultures, and to document traditional values and observations regarding their use within the local and regional landscape.
Aboriginal community monitors that participated in the 2010 supplemental rare plant survey included: Edna Acko and Beatrice Harding for Doig River First Nation; Harry Lawrence for Duncan's First Nation; Peter Joachim for Horse Lake First Nation; Tony Savard for Kelly Lake Cree Nation; Lloyd and Eldon Gauthier for Kelly Lake First Nation; Shirley Letendre for Kelly Lake Métis Settlement Society; Dorris Jackson for McLeod Lake Indian Band; Vern MacDonald for the North East Métis Association of BC; Beatrice Paton for Saulteau First Nation; and Kayla Brown for West Moberly First Nation.
5.1 Traditional Ecological Knowledge Results Aboriginal community monitors identified a complex use of plants and fungi for traditional purposes. Plants are traditionally harvested for a variety of reasons including for food use, utilitarian purposes, and for medicinal, ceremonial and spiritual activities. Of note, the traditional knowledge of medicinal plants is considered proprietary to each community and individual medicinal practitioners. While much traditional knowledge was shared during the field assessment, only general statements regarding medicinal plants and their location relative to the pipeline route will be provided here. Participants informed the staff that every plant in the boreal forest has a use for Aboriginal people. Timber, such as balsam poplar, trembling aspen, white and black spruce, lodgepole pine, and birch is extensively used in the construction of utilitarian objects, for medicinal purposes, for tanning hides and as a source for firewood. A number of plants are harvested for food consumption, including a number of roots and berries such as cranberries, saskatoons, raspberries, strawberries, soap berries and gooseberries, as well as cow parsnip and spruce gum, and for teas, including field mint and Labrador tea. Many plants are harvested for medicinal uses throughout the region, and include yarrow, fireweed, field mint, puffballs, rosehips, common cattail, among others. A number of plants and fungi also have spiritual and ceremonial significance for Aboriginal people. The potency of each medicine relates specifically to individual harvesting locations, the quality of plants, assemblage of plant species, and overall health of the plants. Traditional plant harvesting methods include tobacco ceremonies, community berry picking and outings to specific locations by Elders who know what medicinal plants are needed by the community.
Relative to the Project, medicinal plants were identified around the water crossings, including along the margins of the rivers, creeks and wetlands, as well as in the forested portions of the Saddle Hills. A number of medicinal and utilitarian plants were harvested during the survey as a method of mitigation. In addition, rare plant species were observed in the Project area, none of which received any recommendations for mitigation strategies by the Aboriginal monitors. A medicinal plant that is difficult to find was identified on the right-of-way on the west side of the Saddle Hills and avoidance was requested by the Horse Lake First Nation community monitor. Due to engineering constraints, this plant will be impacted at this location. No other concerns were expressed during the vegetation survey by the Aboriginal participants relative to potential impacts to plants and fungi used for medicinal, spiritual, food consumption and utilitarian purposes.

6.0 DISCUSSION AND MITIGATION RECOMMENDATIONS
6.1 Supplemental Work A summer field visit is recommended to install staking and flagging near rare plant populations and communities to facilitate mitigation measures (e.g., transplanting).
6.2 General Vegetation Recommendations Although the Project has been aligned to minimize environmental impacts, some impacts will inevitably occur during the construction phase and throughout the operational life of the pipeline.
A selection of general mitigative measures to reduce potential environmental impacts to vegetation during construction and/or operation of the pipeline are summarized in Table 5 a complete description of mitigation which relates to vegetation is provided in the EPP prepared for this Project (TERA 2010b).
TABLE 5
GENERAL VEGETATION MITIGATION MEASURES
Concern Mitigation Measures Loss or • The pipeline has been aligned to follow existing linear disturbances as much as practical and the proposed construction right-of-way width Alteration of kept to a minimum to minimize loss of native vegetation to the maximum reasonable extent. Native • Do not clear timber, stumps, brush and other vegetation beyond marked proposed construction right-of-way boundaries. Vegetation • Ensure lands with native vegetation are seeded with an appropriate native seed mix. Ensure seed mixes are free of noxious weed seeds. • To facilitate rapid regeneration, it is preferred that shrubs be mowed, rather than grubbed or wholly removed, if feasible. • To the extent possible and where appropriate, use matting or minimal stripping to avoid disturbance to ground layer vegetation. Where appropriate, allow areas to naturally revegetate. • Clean-up and reclamation should be completed following construction as soon as weather conditions permit. Revegetation • Small trees and shrubs will be cut at ground level and the vegetative mat left intact, whenever practical, to limit disturbance to the low of Disturbed vegetation root systems, and promote rapid shrub regeneration. Footprint • Maintain soil productivity and potential for vegetation growth by implementing appropriate soil handling measures as outlined in Appendix D of the EPP. • Restore native vegetation along disturbed areas of the proposed pipeline right-of-way by seeding disturbed non-wetland areas with native species, planting live shrub (e.g., willow) cuttings salvaged from the proposed construction right-of-way or adjacent areas, where warranted (e.g., at riparian areas), and planting native tree species, where appropriate, and in consultation with appropriate regulatory authorities (i.e., BC MOE, BC MOFR). Allow natural regeneration were no erosion potential exists. • Implement appropriate reclamation measures as indicated on the Environmental Alignment Sheets and as described in the EPP to address site-specific conditions that may result in revegetation problems. • Restrict vehicle access over newly seeded areas. • Monitor the effectiveness of revegetation efforts during post-construction monitoring (PCM) of the proposed construction right-of-way. Inspect moderate and steep slopes during regular aerial patrols. Undertake additional remedial work, where warranted. Mountain • The route lies within the Salvage/Inactive EBBMA for Mountain Pine Beetle. If Mountain Pine Beetle is identified as an issue along the Pine Beetle pipeline route during supplemental surveys, NGTL will consult with the appropriate regulatory authority and if required, develop mitigation to prevent the spread of this pest. • Since clearing is scheduled to commence in August 2010, within the flight period for mountain pine beetle, an appropriate strategy for handling, shipping and disposing of woody material infested with bark beetles should be developed in consultation with the appropriate regulatory agency (ASRD 2010, BC MOFR 2007).
6.3 Rare Plant and Rare Ecological Community Recommendations In accordance with the spirit and intent of the Environmental Assessment Best Practice Guide for Wildlife at Risk in Canada (Canadian Wildlife Service 2004), TERA has developed site-specific mitigative measures for all occurrences of rare plant species and rare ecological communities observed along the proposed pipeline route. Recommended mitigative measures are intended to eliminate or minimize potential construction-related impacts to occurrences of rare plants and rare ecological communities. TERA recommends that PCM be conducted for all occurrences of rare plants and rare ecological communities impacted by the Project, one year following construction and clean-up activities.
Recommended site-specific mitigative measures are summarized in Table 6. Mitigation measures for rare plant and rare ecological community occurrences are also detailed in Table 1 of the EPP and are shown on the Environmental Alignment Sheets (TERA 2010b).

Provincial (S) ranks are assigned by the provincial and federal Conservation Data Centre(s); in cases of conflict or missing data, the provincial CDC will have preference. Ranks range from 1 (five or fewer occurrences) to 5 (demonstrably secure under present conditions); all definitions below are from NatureServe 2009b. 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).
Page 43 Page 43 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. 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. T = Designates a rank associated with a subspecies. (W) = Watch List: elements for which ANHIC wants or needs to collect more information (ANHIC 2009). 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) (NatureServe 2009b). Only global ranks of concern (G1 to G3) or questionable ranks are displayed.

Provincial (S) ranks are assigned by the provincial and federal Conservation Data Centre(s); in cases of conflict or missing data, the provincial CDC will have preference. Ranks range from 1 (five or fewer occurrences) to 5 (demonstrably secure under present conditions); all definitions below are from NatureServe (2009b). 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 Page 49 Page 49 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. ? = 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. BC Provincial List (BC MOE 2010c). Only Red and Blue list designations are displayed. Red List: Includes species that have been legally designated as endangered or threatened under the Wildlife Act; are extirpated; or are candidates for such designation. Blue List: Includes species not immediately threatened but of concern because of characteristics that make them particularly sensitive to human activities or natural events. 3. 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 2009b).
