Landscare of Subarctic Manitoba near Churchill

The definitions of Taiga (https://en.wikipedia.org/wiki/Taiga) and Tundra (https://en.wikipedia.org/wiki/Tundra) describe distinct biomes. I find the distinctions difficult to separate near Churchill. Taiga is generally treed and without permafrost. Tundra is treeless and has permafrost.

The land around Churchill has permafrost and also trees, although the trees would not constitute a forest.

Churchill has polar bears rather than grizzlies, although, interestingly, these two plus black bears have all been spotted near each other in more forested areas of subarctic Canada.

I cite Wikipedia as introductions to the regions. There is and will continue to be much research about arctic and subarctic regions.

Polar Bear Near Churchill MB

At this time of year there were few polar bears. I was three in all. They are still back away from Hudson Bay, with little to eat and so looking gaunt and muddy.

They are extremely strong swimmers. As soon as the ice pack begins to form in the Bay they go to it and begin to feed on seals. They remain on the ice throughout the winter and do not come ashore again until the ice is gone.

Climate change does not bode well for this life cycle.

Manitoba: Looking Directly Toward Hudson Bay Near Churchill

The day we were here at Prince of Wales Fort National Historic Site, across the Churchill River from Churchill, there were two polar bears in and out of the river and walking along the shore.

Visitors to that shore and the fort, and guides and masons working at the fort, are guarded every day by men on 4-wheelers with rifles capable of “lethality.”

We never saw those bears and were hurried along into the fort and back again to the boats. The bear danger is not taken casually.
