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. |
A small portion of boreal caribou habitat in the Northwest Territories northern range falls within the Southern Arctic ecozone and the Taiga Cordillera ecozone. Currently, there is no information available on boreal caribou habitat use or biophysical attributes in either of these ecozones. Biophysical attributes in the Taiga Plains ecozone will be used to describe the type of habitat needed for the identification of critical habitat for boreal caribou in the Southern Arctic and Taiga Cordillera ecozones.
