Three stallions and one mare were dispatched on Day 4 due to blindness in one eye, a non-life-threatening condition.
The death rate is 1.3%.
The capture total includes 260 stallions, 302 mares and 43 foals.
Youngsters represented 7.1% of the animals gathered, consistent with a herd growth rate of one to two percent per year.
Of the adults, 46.3% were male and 53.7% were female, no indication of an abnormal sex ratio.

- Horses allowed by plan: 555
- Pre-gather population: 3,375
- Forage assigned to horses: 6,660 AUMs per year

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 severely limited by the bureaucrats, who have assigned most of their food to the public-lands ranchers.
