One of the oil sands industrys most pressing concerns is its impact on woodland caribou herds. As an iconic Canadian species, and something of a bellwether for boreal forest health, we all want to see caribou thrive.
The first big declines of the woodland caribou in Alberta were observed in the late 1940s and the early 1970s, linked to extensive logging in old-growth forests. Caribou are dependent on old-growth forests because only there can they find abundant amounts of the slow-growing lichen on which they depend for 70 per cent of their diet.
Today, the principal threat to specific caribou sub-populations comes from oil sands development and associated road building and seismic lines within their roaming areas. The woodland caribou is a migratory species, so roads and lines can easily disrupt and fragment their habitat. Moreover, even if the actual area of habitat disturbed by roads and seismic lines is physically small, the amount of habitat that becomes unavailable to the caribou may be much greater, because they cannot or will not cross the disturbed areas.
As I've stated, caribou thrive amongst commercial development in Alaska.
