The death rate of the bison herd managed by a North Dakota tribe is twice the acceptable average, according to the Humane Society.

A Human Society regional director inspected the Mandan, Hidatsa and Arikara Nation's bison herd last month. The tribe is accused of not feeding the animals and of ignoring them, allegations officials deny.

The herd comes from excess animals from the Theodore Roosevelt National Park. The tribe and the park have agreed to suspend transfers for a year.
