Thirty to 50 horses living on the Pryor Mountain Wild Horse Range would be removed from the area in 2012 under a proposal under consideration by the Bureau of Land Management.

The roundup would specifically target one-half to two-thirds of the 1- to 3-year-olds.

The BLM’s Billings Field Office has released its preliminary environmental assessment concerning the roundup and is taking comments through Jan. 6. The horses would be removed without hazing by helicopters, instead using traps baited with food, traps set up around watering holes or herding.
