The horse death rate is 1.3%.

The horse total includes 722 stallions, 805 mares and 310 foals.

Youngsters represented 16.9% of the horses captured.

Of the adults, 47.3% were male and 52.7% 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.

The trap is in the North Twin Peaks Home Range.

The HMA is subject to permitted grazing.
