The identification of critical habitat for boreal caribou is described by three factors for each local population: i) Location of habitat; ii) Amount of habitat; and iii) Type of habitat.
A) Location:Where critical habitat is found.

C) Type: Biophysical attributes.
Type of selection | Description |
---|---|
Broad scale |
Mature forests (jack pine, spruce, tamarack) of 100 years or older, and open coniferous habitat. Large areas of spruce peatland and muskeg with preference for bogs over fens and upland and lowland black spruce forests with abundant lichens and sedge and moss availability. |
Calving |
Open coniferous forests, tussock tundra, low shrub, riparian, recent burned areas, south and west aspects and Hills and higher locations. |
Post-calving |
Muskegs or areas with access to muskegs, open meadows on higher ground, close to water (lakes and rivers) and mixed bush areas. |
Rutting |
Open coniferous and mixedwood forests, low shrub, riparian, tussock tundra, recent burns and west aspect. Still use muskegs that harbor ground lichen and sedges, mixed bush areas, areas of higher ground. |
Winter |
Open coniferous forests (black spruce and pine) that provide adequate cover with abundant lichens, riparian areas. Caribou observed in muskeg areas in early winter. |
Travel |
Females show high fidelity to calving sites among years (i.e. within 14.5 km). |
Avoidance |
Avoid edge habitat. |

4 Total Habitat Disturbance is non-overlapping which means anthropogenic disturbances and burned areas that overlap are not counted twice in the total.
The identification of critical habitat for boreal caribou is described by three factors for each local population: i) Location of habitat; ii) Amount of habitat; and iii) Type of habitat.
A) Location:Where critical habitat is found.
Figure 1: Keymap of the general location of the local population (in red).
Figure 2: The geographic boundary within which critical habitat is located (in grey).
B) Amount: Quantity of critical habitat.

1 Total Habitat Disturbance reflects loss of functional habitat. It will be more than the associated disturbance footprint (e.g. 100 ha footprint could lead to 400 ha loss of functional habitat). |
C) Type: Biophysical attributes.
Type of selection | Description |
---|---|
Broad scale |
Late seral-stage (> 50 yrs old) conifer forest (jack pine, black spruce, tamarack), treed peatlands, muskegs or bogs, use dry islands in the middle of muskegs, with abundant lichens. Hilly or higher ground and small lakes. |
Calving |
Bogs and mature forests selected for calving as well as islands and small lakes. |
Post-calving |
Forest stands older than 50 yrs. |
Rutting |
Mature forests. |
Winter |
Treed peatlands, treed bog and treed fen and open fen complexes with > 50% peatland coverage with high abundance of lichens. |
Avoidance |
Avoid upland and fen habitats, aspen dominated stands, immature stands and large rivers all year round. |

Disturbance Type and Amount:
Burned Areas = 37%
Buffered3 Anthropogenic (no reservoirs) = 63%
Total Habitat Disturbance = 80%4
3 Buffered means a 500m buffer is applied to linear and polygonal disturbances.
4 Total Habitat Disturbance is non-overlapping which means anthropogenic disturbances and burned areas that overlap are not counted twice in the total.
