Canada has played a major role in one of the United States’ biggest conservation efforts.
“We basically went up the Rocky Mountain chain to find wolves that were similar to the ones that used to live in Yellowstone and that just took us up the backbone of the Rockies to Alberta and B.C.,” said wildlife biologist Doug Smith.
Smith led the more than 30-year-long efforts to repopulate wolves in Yellowstone National Park.
The species had been wiped out in the western U.S. by the 1930s.
Now there are nine packs of wolves in Yellowstone with 92 wolves in total.
“Yellowstone has become the best place in the world to view free-ranging wolves,” Smith told CTV News.
Smith presents Wild Wolves of Yellowstone as part of the National Geographic Live series at the Jack Singer Concert Hall on April 27 and 28.
