Data quality is poor. The figures above are based on the daily reports. They may differ from the totals at the gather page.
A colt was found dead in the pens on Day 8, cause unknown. A stallion was put down after breaking his neck on panel while loading.
On Day 11, two foals were put down for injuries and wounds.
The horse death rate is 1.5%.
The horse total includes 472 stallions, 539 mares and 200 foals.
Youngsters represented 16.5% of the horses captured. Of the adults, 46.7% were male and 53.3% were female.
The herd can’t be growing at a rate of 20% per year with a birth rate of 17% per year.
A better estimate would be 12% per year, assuming a death rate of 5% per year.
Body condition scores since Day 7 ranged from 4 to 5.
The trap is in the North Twin Peaks Home Range (whatever that means).
The HMA is subject to permitted grazing.
Day 11 ended with 177 unaccounted-for horses and no unaccounted-for burros.
Mares treated with fertility control will be returned to the area at a later date.
