Triple B Roundup, Day 23

The incident began on July 17.  Gather stats through August 8:

  • Target: Horses
  • Type: Planned
  • Method: Helicopter
  • Category: Cruel and costly
  • Captured: 867, up from 747 on Day 21
  • Average daily take: 37.7
  • Capture goal: 1,900
  • Removal goal: 1,800
  • Returned: None
  • Deaths: 17, up from 16 on Day 21
  • Shipped: 801, up from 712 on Day 21

The figures above are based on the daily reports.

A mare was put down on Day 23 due to pre-existing conditions.

The death rate is 2.0%.

The capture total includes 305 stallions, 417 mares and 145 foals.

Youngsters represented 16.7% of the animals gathered.

Of the adults, 42.2% were male and 57.8% 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 observed percentages of stallions and mares cannot be attributed to a simple random process centered at 50% males / 50% females.

Abnormal sex ratios are often found in herds subject to the Montana Solution but not double-digit birth rates.

Body condition scores were not given.

The location of the trap was not disclosed.

The Complex and surrounding lands are subject to permitted grazing.
