Do caribou always return to the same spot on their winter range, just as they always go back to their calving grounds?
Caribou travel to find a good supply of food. Since lichens (their winter diet) grow very, very slowly after fire — it can take between 50 and 100 years — caribou move on to another area once they have completely grazed a section of the range. If fire has destroyed lichens and other plant growth, this will also force caribou to another part of their range.
