Helicopters did not fly on Day 13.

A stallion and mare were put down on Day 12 due to marginal BCS.  A mare was put down on Day 13 due to club feet.  They survived the chase and would be alive today if there was no roundup.  The death rate is 2.5%.

The capture total includes 194 stallions, 234 mares and 87 foals.

Youngsters represented 16.9% of the animals captured.  Of the adults, 45.3% were male and 54.7% 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 5% death rate.

Body condition scores were not given.

The location of the trap site was not disclosed.

The Complex and surrounding lands are subject to permitted grazing.
