This ecozone extends along most of the border between the Yukon and
The Taiga Cordillera contains the northernmost of the Rocky mountains
in Canada and also some of its highest waterfalls, deepest canyons and
wildest rivers. Mountains block much of the precipitation, which averages
250 to 300mm per year. Its northerly position gives it cold winters
(-22ºC average temperature) with very short days and short cool summers
(average temperature 8ºC). Snow lasts on the ground for six to eight
months of the year.
Most of the ecozone is covered with steep mountains and narrow valleys,
although the northwest contains wetlands and rolling hills and the north
contains tundra; this tundra is above the treeline, so only smaller
plants are found there.
Location on the slopes of the ecozone determines which plants are to
be found. Western-facing slopes recieve more precipitation than those
that face the east, while southern slopes are warmer, brighter and drier
than north-facing slopes. Distinct zones also occur as altitude increases.
Some of the trees found here include paper
paper birch, blue-green willow, Bebb willow, and net-veined willow.
Other plants include
mountain aven, eriacaceous shrubs, sedge, cottongrass, Labrador tea,
fire snag, larkspur, forget-me-not, wooly lousewort, arnica, hedysarum,
white camas, purple mountain saxifrage, yellow mountain saxifrage, alpine
bearberry, arctic white heather, alpine bearberry and prickly saxifrage.
As with the plants, the animal species to be found depend upon their
location in the ecozone. Alpine regions, lowland forests and wetlands
all have characteristic species.
Large carnivores that are found here include black
The large herbivores include Dall’s
Small carnivores such as coyote,
can be found here, preying in part on arctic
ground squirrel, American
and brown lemming.
Some of the characteristic birds of prey are gyrfalcon,
golden eagle, bald
Shorebirds and seabirds that are found here include spotted
gull, and mew
gull. The songbirds of the Taiga cordillera include common
water pipit, violet-green
swallow, and gray
jay. Waterfowl such as Canada
and arctic loon
are found here. Ruffed
ptarmigan, and white-tailed
ptarmigan are some of the birds of the forest.
Amphibians and Reptiles
The Taiga Cordillera is too far north for amphibians and reptiles.
Predators such as the northern pike feed on species including lake whitefish
and lake chub. Chinook salmon and chum salmon come in from the ocean
Two of the mollusc species found in this ecozone are the muskeg
stagnicola and arctic-alpine
Only a few hundred people live here, and subsistence activities are
the norm. Otherwise, there is some tourism, but no major urban centres
or industries exist here.
