Black, Grizzly and Polar Bears Now All Found in Churchill Candice Gaukel Andrews July 30, 2019 0

For the first time, North America’s three bear species—black, grizzly and polar—have been documented sharing the same spot. And that spot happens to be one that is very dear to Natural Habitat Adventures and its travelers: Churchill, Manitoba, Canada, our polar bear tour headquarters.

Recently, in November 2018, a paper published in the peer-reviewed journal Arctic Science, titled Novel range overlap of three ursids in the Canadian subarctic, described how cameras set up by University of Saskatchewan researchers in Wapusk National Park on the shore of Hudson Bay near Churchill captured the proof that had scientifically never been substantiated anywhere before.

And remarkably, this doesn’t look like a case of science just catching up to what’s been going on all along but not yet noticed by us. Researchers have been conducting studies on that particular piece of ground since the 1960s.

So why is this happening now? The study’s lead author, Douglas A. Clark, says that the presence of all three North American bear species in the same area is “consistent with expected ecological responses to the amplified impacts of climate change on high-latitude ecosystems.”

In other words, climate change is likely a factor.
