BLM said today that 365 wild horses would be gathered from the Challis HMA in central Idaho, beginning on or about November 5, with 244 permanently removed.
Mares returned to the range will be treated with contraceptives, according to the news release. The announcement did not indicate of any of the studs would be gelded.
The roundup will be carried out with helicopters and will be open to public observation.
The HMA covers 168,720 acres and has an AML of 253, for an aimed-at population density of 1.5 wild horses per thousand acres. The target density across all HMAs is one animal per thousand acres.

The HMA intersects seven grazing allotments, according to Section 3.8 of the final Environmental Assessment for the HMA Management Plan. Table 2 in Appendix G indicates that the entire parcel is subject to domestic livestock grazing.
Captured animals will be taken to the off-range corrals in Bruneau.
Gather stats and daily reports will be posted to this page.
