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.

Type of selection | Description |
---|---|
Broad scale |
Mature conifer uplands and conifer/tamarack dominated lowlands. |
Calving |
Forested wetlands/treed bog, old burns, sparse conifer and dense spruce. Need lichen availability. |
Post-calving |
Peatland with forested islands, islands, and shorelines selected during summer. |
Rutting |
Semi-open and open bogs and mature conifer uplands selected during rutting. Terrestrial lichens and arboreal lichens, sedges and bog ericoids (Andromeda glaucophylla, Chamaedaphne calyculata, Kalmia polifolia, Ledum groenlandicum) are important sources of forage. |
Winter |
Mature coniferous stands. |
Travel |
Travel mainly in conifer forests, avoiding open habitats (e.g. lakes, disturbed areas, etc.) when migrating from summer to winter habitat. |
Avoidance |
Shrub-rich fens are avoided during calving. |

Broad scale |
Upland tundra dominated by ericaceous shrubs (Ericaceae spp.), lichen, grasses and sedges. |

String bogs, treed bogs, small open wetlands (< 1 km²), large muskeg, marshes along water bodies. Barren grounds. |

Forested wetlands. Hilly areas, coastal sites, along shorelines of water bodies (rivers, lakes, creeks), marshes with lichen availability. |
Rutting | Open wetlands, swamps. Mature forests, mountainous terrain with forests of black spruce, tamarack and pine trees with abundant lichen. |
Winter |
Forested areas are used in years of low snow accumulation otherwise winter habitat selection reflects general avoidance of deep snow, including use of tundra habitat at higher elevations in mountainous regions and bogs along lakes or oceans. |
Travel |
Connectivity between selected habitat types important given reported patterns of movement among caribou. |
Avoidance |
Avoidance of roads and areas recently burned. |
