The figures above are based on the daily reports.

No animals were gathered on Day 8.

Two jacks were put down on Day 7 due to pre-existing conditions, followed by a jack and jenny on Day 8.

The burro death rate is 1.2%.

The burro total includes 338 jacks, 405 jennies and 62 foals.

Youngsters represented 7.7% of the burros captured.

Of the adults, 45.5% were male and 54.5% were female.

The herd can’t be growing at a rate of 20% per year with a birth rate of 8% per year.

A better estimate would be 3% per year, assuming a death rate of 5% per year.

Low birth rates are often associated with the Montana Solution but the Blue Wing HMAs are not on the fertility control list in the latest schedule.

Body condition scores were not given.

The location of the trap was not disclosed.

The HMAs in the Complex are subject to permitted grazing.
