Which habitats can gray wolves live in?

The gray wolf is an incredibly adaptable species that historically occupied a vast range across the Northern Hemisphere. It is capable of living in nearly every type of habitat, including forests and tundra.123

The only environments where gray wolves do not typically live are tropical forests and the most arid deserts. While they are often associated with wilderness areas, wolves are also capable of thriving in close proximity to human populations, provided that they are not excessively persecuted and that sufficient food sources are available.14
