Twin Peaks Roundup, Day 21

The incident began on July 23.  Gather stats through August 12:

  • Target: Horses and burros
  • Type: Planned
  • Method: Helicopter
  • Category: Cruel and costly
  • Horses captured: 2,110, up from 2,109 on Day 18
  • Burros captured: 200, up from 38 on Day 18
  • Average daily take: 100.5 horses, 9,5 burros
  • Capture goal: 1,978 horses, 339 burros, horses increased to 2,106 on Day 17
  • Removal goal: 1,868 horses, 339 burros, horses increased to 1,996 on Day 17
  • Horses returned: None
  • Burros returned: None
  • Horse deaths: 31, up from 28 on Day 18
  • Burro deaths: None
  • Horses shipped: 2,075, up from 1,905 on Day 18
  • Burros shipped: 97, up from 38 on Day 18

The figures above are based on the daily reports, not the totals posted by the BLM.

The trap was moved on Day 19 and operations shifted to burros on Day 20.

One burro and 27 horses have been returned to the HMA but this has not been documented in the daily reports.

A mare was found dead in a holding pen on Day 19, cause unknown.  Another mare, unable to move through the holding area, was euthanized.  A third mare collapsed in the holding area and could not be revived.

The horse death rate is 1.5%.

These losses would occur in catch-treat-release but they would be tolerated by the advocates, a small price to pay for greater use of the Montana Solution.

The horse total includes 818 stallions, 942 mares and 350 foals.

Youngsters represented 16.6% of the horses captured.

Of the adults, 46.5% were male and 53.5% were female.

The burro total includes 101 jacks, 78 jennies and 21 foals.

Youngsters represented 10.5% of the burros gathered.

Of the adults, 56.4% were male and 43.6% were female.

The herd can’t be growing at a rate of 20% per year with a birth rate of 11%.

A better estimate would be 6% per year, assuming a death rate of 5% per year.

Body condition scores on Days 20 and 21 ranged from 4 to 5.

The trap is in the Skedaddle Home Range.

The HMA is subject to permitted grazing.

Day 21 ended with four unaccounted-for horses and 103 unaccounted-for burros.

The horse capture goal has been reached and the burro goal is 59% complete.

Mares treated with fertility control will be returned to the area at a later date.
