Theodore Roosevelt park in ND plans 2-day bison roundupDICKINSON, N.D. (AP) — Officials at Theodore Roosevelt National Park have scheduled a bison roundup for two days starting Tuesday.
Park Superintendent Valerie Naylor told the Dickinson Press that about 225 animals will be rounded up from the park's North Unit and shipped to the Blackfeet Nation of Montana and the Spirit Lake Nation of North Dakota.
A helicopter will be used to herd the bison.
"We have to round up the bison periodically because the bison don't have any natural predators in the park and so their numbers continue to grow unless we take action," Naylor said.
Naylor says the North Unit will have a population of about 100 after the roundup.
"We remove bison based on their age, sex category so we keep a nice complement up there," Naylor said. "They will double their numbers every three years or so, so the herd will grow right back."
Park officials say the roundup will be closed to the public. The last bison roundup was two years ago in the park's South Unit.
