Saskatoon, Polar bears are intensely curious animals that often bring them into contact with people, putting both species at risk. As the Arctic climate warms, some polar bears are spending more time on shore, away from their sea ice habitats. Research in Wapusk National Park in Manitoba and the Churchill Northern Studies Centre found that human presence at camps had no effect on bear visits, but the length of the ice-free season did.
The study, which used trail cameras to monitor bear visits between 2011 and 2021, found that the longer Western Hudson Bay remained ice-free, the more frequently bears visited the study sites. This was unexpected, as previous research suggested that hungrier bears would be more likely to approach human infrastructure.
Instead, the study found that body condition may play a different role in polar bear-human interactions. A skinny bear might be more likely to aggressively try to obtain human food sources or prey on people, while a bear under less nutritional stress might be less aggressive. The findings suggest that sea ice loss may not lead to more interactions with people just because polar bears are thinner or hungrier.
The study's results align more closely with Indigenous observations, which have long suggested that bears who come into communities are not necessarily in poorer condition than expected. The findings have implications for current approaches to reducing the risk of polar bear-human conflicts.
