Triple B Roundup, Day 9

The incident began on July 17.  Gather stats through July 25:

  • Target: Horses
  • Type: Planned
  • Method: Helicopter
  • Category: Cruel and costly
  • Captured: 346, up from 285 Day 7
  • Average daily take: 38.4
  • Capture goal: 1,900
  • Removal goal: 1,800
  • Returned: None, no change from Day 7
  • Deaths: 8, up from 6 on Day 7
  • Shipped: 319, up from 246 on Day 7

A stallion died of a broken neck on Day 9 and a mare was euthanized, increasing the death rate to 2.3%.

The total includes 118 stallions, 163 mares and 65 foals.

Youngsters represented 18.8% of the animals captured.  Of the adults, 42.0% were male and 58.0% were female.

The herd can’t be growing at a rate of 20% per year with a birth rate of 19% per year.

A better estimate would be 14% per year assuming a 5% death rate.

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 site was not disclosed.

The Complex and surrounding lands are subject to permitted grazing.
