JACKSON, Wyo. (AP) — The number of bison moving from Grand Teton National Park to the National Elk Refuge is up this year.

About 700 bison moved from the park to the refuge between July 28 and Aug. 3, about three-quarters of the Jackson Hole herd.

Refuge biologist Eric Cole told the Associated Press  that he estimates that more bison will be on the refuge for the beginning of hunting season Wednesday than on any other opening day.

Cole said more bison could be harvested during the hunting season as a result. However, he said the downside is bison are already consuming forage meant for winter.

The 100-year-old refuge serves primarily as winter range for elk in the area.

Hunting continues periodically through Jan. 6.
