Young animals can be hurt in stampedes when a herd is startled by a polar bear, human hunters or even a low-flying airplane. With no human witnesses, biologists said the deaths may have been from "disturbances" that led to trampling.

Biologists who examined the Alaska carcasses were protected by armed guards standing watch for polar bears.

"It was definitely crisscrossed with bear tracks all over the place," said biologist Jill Prewitt of the Alaska SeaLife Center.

York noted that large concentrations of walruses on land can also attract polar bears and lead to increased human-bear conflict. WWF is working with local communities across the Arctic coast to mitigate such conflicts and share information with communities on how to deal with the significantly increasing numbers of walruses and polar bears on land.
