ROCK SPRINGS, Wyo. (AP) — The Bureau of Land Management is planning to begin gathering wild horses in southwest Wyoming this week.

A BLM press release says horses will be collected from the Adobe Town and Salt Wells Creek herd management areas located south of Interstate 80 to the Wyoming-Colorado border from Rock Springs to Wamsutter.

The BLM plans to gather about 700 wild horses and treat female horses with fertility control. The two areas are located on public, private and state land in Sweetwater and Carbon counties.

The roundup is expected to last roughly four weeks or until the designated number of excess wild horses have been removed. The last area roundup was conducted in October 2010.

Animals removed from the areas will be available for adoption.
