MEDORA, N.D. (AP) — Officials at Theodore Roosevelt National Park in western North Dakota are rounding up wild horses this week.
The horses will be sold at auction in Wishek on Saturday in an effort to thin the park's herd to a size the park can accommodate.
The park maintains a demonstration herd of what it calls feral horses to commemorate the wild horses that roamed the badlands when Theodore Roosevelt ranched in the area during the 1880s. Park officials say the herd has grown to more than 200 animals. About 100 of them will be auctioned.
The park has conducted more than 25 horse roundups since 1954. The last one was in 2009. Officials hope a contraceptive vaccine they're experimenting with will succeed and eliminate the need for such roundups.
