Low Potential: May occur in RAA but the species was not observed during field studies (Appendix 9.1) nor Breeding Bird Atlas surveys (Table 9.7); no habitat identified in the LAA.
Canada Warbler Cardellina canadensis
Threatened, Schedule 1
Threatened S4B Threatened Yes (2016) Canada Warbler breeds in various habitats across its range, but is almost always associated with moist forests with a dense, deciduous shrub layer, complex understory, and available perch trees. Nests are built on or near the ground (Reitsma et al. 2010). They are placed on moss and raised hummocks, within holes of root masses, rotting tree stumps, clumps of grass, rock cavities, etc. (Reitsma et al. 2010).
No - Recovery strategy says information lacking with schedule determined in future.
Moderate Potential: Suitable habitat exists in RAA but the species were not observed during field studies (Joro 2015).
Chimney swift Chaetura pelagica
Threatened, Schedule 1
Threatened S2B Threatened No - status report only Chimney Swift nesting habitat consists of vertical surfaces such as chimneys; spend most of the day foraging for insects on the wing. It is difficult to associate the species with a single type of habitat; its presence in a particular area largely depends on the availability of suitable nesting sites (DeGraaf and Rappole 1995) and the abundance of insects (Kaufman 1996).
No - EC does not identify specific critical habitat.
Very Low Potential: May occur in RAA but not observed during field studies (Appendix 9.1) nor Breeding Bird Atlas Surveys (Table 9.7) and no suitable habitat identified in LAA.

Eastern Whip-poor-will Antrostomus vociferus
Threatened, Schedule 1
Threatened S3B Threatened Yes (2015) Forests (e.g., deciduous, mixedwood, coniferous, treed wetlands) and open habitats (e.g., shrublands, fallow fields, regeneration following fires or clear-cuts, rock and sand outcrops; shrubby wetlands) form a mosaic.
No - Not in LAA; some critical habitat near Ontario.
High Potential: May occur in RAA and habitat for the species exists in the LAA; the species was not observed during field studies nor Breeding Bird Atlas surveys.
Eastern Wood-pewee Contopus virens
No schedule, no status
Special Concern
S4B Not listed COSEWIC Status report only
In Canada, the Eastern Wood-Pewee breeds mostly in mature and intermediate-age deciduous and mixed forests (less often in coniferous forest) having an open understory (Ouellet 1974; Godfrey 1986; Peck and James 1987; Gauthier and Aubry 1995; Falconer 2010; Burke et al. 2011). It is often associated with forests dominated by Sugar Maple (Acer saccharum), elm (Ulmus sp.) and oak (Quercus sp.; Graber et al. 1974). It is usually associated with forest clearings and edges within the vicinity of its nest (Hespenheide 1971; Peck and James 1987).
No - EC does not identify specific critical habitat; LAA/RAA on northern fringe of range -COSEWIC
Low Potential: May occur in RAA and habitat for the species exists in the LAA; however, the species was not observed during field studies (Joro 2015) nor evaluations conducted by Breeding Bird Atlas surveys (Table 9.7).
Olive-Sided Flycatcher Contopus cooperi

Short-Eared Owl Asio flammeus Special Concern -Schedule 1
Special Concern
S2S3B Threatened No - Management plan (2016)
Short-eared Owls occur in a variety of open native habitats: grasslands, Arctic tundra, taiga, bogs, marshes, coastal wetlands, coastal barrens, estuaries and grasslands dominated by sand-sage (Artemisia filifolia). There is little specific information regarding habitat preferences at the landscape scale, but a mosaic of grasslands and wetlands provides optimal breeding and foraging habitats (Wiggins, 2004).
No - EC does not identify specific critical habitat.
High Potential: Migrate through the RAA in low numbers; habitat exists in the LAA and the species was observed during field studies (Joro 2015) but not during Breeding Bird Atlas Survey (Table 9.7).
Waterbirds
Horned Grebe Podiceps auritus
No schedule, no status
Special Concern
Not listed
Not listed COSEWIC Status Report only
In Manitoba, the Horned Grebe breeds throughout the province with the exception of certain eastern regions. It is probably more common in the Minnedosa region, but its abundance in the Prairie region fluctuates according to the water level. The species is generally less abundant in summer in the southeastern part of the province. Some individuals breed in Churchill, mainly in marshes near Akudlik and in the Goose Creek region (Holland and Taylor, 2003).
No - EC does not identify specific critical habitat.
Moderate Potential: May occur in RAA in low numbers; limited habitat for the species exists in the RAA. The species was not observed during field studies (Joro 2015) nor evaluations conducted by Breeding Bird Atlas Survey (Table 9.7).
Trumpeter Swan Cygnus buccinator
No schedule, no status
Not at risk S1B Endangered Not applicable It prefers nesting is shallow wetlands with stable water levels, abundant and elevated nest sites, abundant and diverse aquatic invertebrates and/or plants and low levels of human disturbance.
N/A. Low Potential: Very low potential for breeding but increased numbers migrating through RAA. Seen during field studies and listed in Breeding Bird Atlas.
Yellow Rail Coturnicops noveboracensis
Special Concern - Schedule 1
Special Concern
S3B Not listed No - Management plan
Yellow Rails inhabit shallow wetlands and other wet areas with grass-like vegetation. Breed in wetlands such as damp hay fields or meadows, floodplains, bogs, upper levels of estuaries, salt marshes (Bookhout 1995, Alvo and Robert 1999, COSEWIC 2009), shallow prairie wetlands, and wet montane meadows (Peabody 1922, Sherrington 1994, Popper and Stern 2000). Preferred wetlands are generally dominated by short, fine-stemmed herbaceous vegetation, especially sedges, as well as other graminoid vegetation of the families Cyperaceae, Poaceae, and Juncaceae. Vegetation structure (e.g. short, grass-like, and dense) is likely more important than its taxon (Robert et al. 2000). Breeding habitats may have up to 50 cm of standing water, but typically nesting sites are less than 15 cm deep (Bookhout 1995, Robert et al. 2000, Wilson 2005). The species' narrow tolerance for shallow water levels likely explains why its abundance at any given site varies dramatically annual (Robert and Laporte 1999, Kehoe et al. 2000, Lindgren 2001).
No- EC does not identify specific critical habitat.
Very Low Potential: May breed in the low numbers in RAA; not observed during field studies nor Breeding Bird Atlas surveys.

High Potential: 116-338 caribou were observed within the RAA during field studies conducted 2011-2013 (Joro 2015, Table 7).
Little Brown Myotis (Bat)
Myotis lucifugus
Endangered, Schedule 1
Endangered S2N,S5B Endangered Yes - combined for little brown, northern myotis and tricolord bat (2015)
Typically, hibernacula for these species are subterranean features, such as caves, abandoned mines, hand-dug wells, cellars, or tunnels where light and noise levels are low; typically contain sections that have relatively stable temperatures (2-10 ˚C) and stable, high humidity levels (>80 %). Hibernacula generally identified in MB, but none identified in the LAA.
No critical habitat in LAA/RAA (Recovery Strategy); closest is Karst formations in Interlake.
Low Potential: Very low potential for hibernacula in RAA. Some potential in LAA to be used during the summer as roosting sites within the forested areas; habitat exists but there were no sightings of the species or hibernacula.
Wolverine Gulo gulo Endangered, Schedule 1
Non-active Not listed
Not listed N/A A wide variety of forested and tundra vegetation associations are used by Wolverines. Habitats must have an adequate year-round supply of food, mainly consisting of smaller prey such as rodents and Snowshoe Hares, and the carcasses of large ungulates, like Moose, Caribou, and Muskox. Females den under snow-covered rocks, logs or within snow tunnels. Wolverines reproduce in areas where snow cover persists at least into April.
No - EC does not identify specific critical habitat.
High Potential: May occur in very low numbers dispersed in LAA. One wolverine was trapped along the RTLs in the RAA between 200 and 2011 (Appendix 9.1, Table 1E). Eight tracks were observed in the LAA during field studies in 2011 (Joro 2015, Table 39).

Loss or alteration of habitat due to clearing and construction near waterbody or bog and fen areas having suitable habitat for the species.
Mortality related primarily to operational use of the road - particularly during breeding or migratory movements between overwintering and nesting sites.
Traditional knowledge, including specific consideration of species at risk, was utilised as part of route selection.
Baseline studies have supported traditional knowledge data for route selection.
Road routing avoids waterbodies except at crossing locations.
Disturbance minimization, e.g., equipment to remain on ROW or within marshalling areas.
Identify areas of non-disturbance around high quality high quality habitat .
Existing water flow patterns, levels and hydrologic regimes will be maintained reclaim disturbed areas and facilitate natural re-vegetation by native plants and seeds.
Inspectors and Contract Administrators will receive training and handbooks to identify all potential species at risk that could be encountered - the Environmental Inspector will be advised when encounters occur and management strategies applied if required.

Note: 1 The level of potential effect was ranked as being ‘low’, ‘moderate’ or ‘high’ based on the extent, frequency, reversibility and ecological context of the potential effect prior to theimplementation of mitigation measures, and the probability of the occurrence of the predicted effect. A predicted effect was considered to be ‘low’ if there is a low probability ofoccurrence, ‘moderate’ if it has a moderate probability of occurrence, and ‘high’ if there is a high probability of occurrence.
