The figures above are based on the daily reports, not the totals posted by the BLM.
The death rate is 1.1%. Three horses died accidentally, 21 were killed deliberately.
The capture total includes 906 stallions, 1,024 mares and 295 foals. The sidebar at the gather page says 904/1,018/297.
Youngsters represented 13.3% of the animals gathered, consistent with a herd growth rate of eight percent per year.
Of the adults, 46.9% were male and 53.1% were female, no evidence of an abnormal sex ratio.
Body condition scores ranged from 3 to 4 on Days 34 and 35.
The location of the trap site was not disclosed.
The Complex is managed primarily for animal agriculture. The National Data Viewer shows habitat loss and grazing allotments. Click on image to open in new tab.
*According to advocates.
Day 35 ended with 6 unaccounted-for animals. This result should be zero based on the totals in the sidebar, suggesting there are errors in the daily reports.
The contractor is shipping them the same day they are captured.
There are no plans to treat any of the captured mares with fertility control pesticides and return them to the range.

Overpopulation means more horses than allowed by plan, not necessarily more horses than the land can support.
The ability of the Complex to sustain wild horses has been limited by the bureaucrats, who have assigned most of their food to the public-lands ranchers.
