One burro and 22 horses have been returned to the HMA but this was not documented in the daily reports.

Three horses were euthanized on Day 18 due to pre-existing conditions and two foals died in temporary holding, causes unknown.

The horse death rate is 1.3%.

The horse total includes 817 stallions, 942 mares and 350 foals.

Youngsters represented 16.6% of the horses captured.

Of the adults, 46.4% were male and 53.6% 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 on Days 17 and 18 ranged from 4 to 5.

The trap is in the North Twin Peaks Home Range.

The HMA is subject to permitted grazing.
