The White bark pine is an uncommon five needle pine that is growing in the dry sub-alpine region in southern British Columbia. Like their name, the pine has a smooth white bark which gets darker the older the tree gets. The high elevations of the Chilcotin Ark are the perfect habitat for the White bark pine and it is home to the healthiest population in Canada, the species is endangered due to mountain pine beetle infestation, white pine blister rust and climate change.
