The incident will comply with a 2013 court order resulting from a case brought by RSGA, according a BLM news release.
The roundup may be a prelude to the RMP amendments that will close three of the HMAs and downsize a fourth if approved.
The writer acknowledged that one of the goals was to reduce trespass onto 899,308 acres of private land in the Wyoming checkerboard, much of it owned by RSGA.
He did not say if Wyoming was a fence-out state.
