As climate change pushes deer north, other animals may lose out

As winters warm, white-tailed deer push ever northward in North America. A recent study in Global Change Biology suggests that climate change is driving these habitat shifts — changes that may further threaten woodland caribou in northern Canada.

The study used 300 remote cameras across the northern Alberta-Saskatchewan border, collecting nearly 80,000 images of white-tailed deer from 2017 to 2021 and using the images to estimate white-tailed deer density in the region over time.
