Detailed Description

USGS Wildlife Research Biologist Heather Johnson uses collar-mounted video cameras to peer into the lives of climate-threatened caribou.

Caribou are an iconic species of Alaska’s Arctic landscapes. On the treeless tundra, herds of caribou numbering in the thousands are a dominant ecological presence, as well as an important source of food for Indigenous and rural communities in the Arctic. Migrating vast distances between their seasonal ranges, caribou are one of many Arctic species forced to adapt to climate-driven shifts in temperature, habitat, and food resources. A major hurdle to studying these animals is logistical: caribou range over vast, remote landscapes, making tracking them costly and even dangerous. In Alaska, USGS researchers are exploring a new tool to study the habits and movements of caribou: collar-mounted video cameras.
