Most of the animals of the
western mountains are found in the parks. Grizzly
and black bear find excellent forage on the
steep slopes cleared by snow slides. Mountain
goats and bighorn sheep graze at high elevations.
Mule deer, white-tailed deer, elk and moose
roam the forests that wolves, cougar and wolverine
also call home. The subalpine ecoregion is also
the habitat of pine martin, lynx, snowshoe hare,
squirrels, porcupine, jays, Clarks nutcracker
and pine siskin. Pikas, hoary marmots, white-tailed
ptarmigan and lemmings find habitats in the
meadows. All of the 2500 mountain caribou in
the world are in southeastern BC and all are
considered vulnerable due to their dependency
on the lichens that grow on old growth trees.
Logging of these ancient
trees has seriously diminished the supply of
arboreal lichens, which alone are the caribous
winter food source. Other research projects
involve the monitoring of migrant bird populations
such as the yellow warbler, American redstart,
song sparrow and Swainsons thrush. The
West Slopes Grizzly Bear Project attempts to
determine their population density and mortality
rate. Radio collars to determine survival rates
and reproductive data are presently tracking
wolverines, considered vulnerable. The long-eared
bat in the Columbia Basin area is at risk of
extinction in BC because, like so many species,
it is highly dependent on the habitats provided
by old growth forests.
