These are pictures from the Grizzly Bear relocation program in Yellowstone National Park. Grizzly Bears, also called the Alaskan Brown Bear, were close to extinction in Yellowstone. Through conservation efforts, the Grizzly Bears are back to a healthy population. Unfortunately campers and tourist in the park still leave garbage at campsites and leave un-burned food in fire pits, which attracts the bears and makes them lose their fear of humans. Bears that continue to be a nuisance end up getting destroyed.
Below is a young bear fitted with a radio collar because he proved to be a problem. The bear was being released but the bear has seemed to have lost its fear of humans and turned and attacked the forest ranger. If the bear heads back to the public areas of the park, it will most likely be destroyed.
