- Herd size (2017): 218,000
The Porcupine herd ranges between the northwest of the NWT, Across northern Yukon to Alaska. According to a 2017 survey, there are about 218,000 animals in the Porcupine herd. The area where the herd calves in Alaska is known as the Arctic National Wildlife Refuge. For many years, there have been attempts to open up the refuge to oil and gas exploitation, a move resisted by the Gwich’in people who rely on the herd, and by environmental organizations.
