Caribou herd migration is affected by deforestation in Northern Canada. Many factors alter a caribou herd’s migration, but traditional routes change most drastically due to human activity. These changes effect the population and overall health of the herd.
Like many migratory species, caribou use an “internal compass” that allows them to sense the Earth’s magnetic field, leading them to follow similar migration routes year after year for generations. This process is still not entirely understood, and is of great interest to scientists around the world.
