The incident began on July 23.  Gather stats through July 27:

  • Target: Horses and burros
  • Type: Planned
  • Method: Helicopter
  • Category: Cruel and costly
  • Horses captured: 787, up from 588 on Day 3
  • Burros captured: 2, no change from Day 3
  • Average daily take: 157.4 horses, 0.4 burros
  • Capture goal: 1,978 horses, 339 burros
  • Removal goal: 1,868 horses, 339 burros
  • Horses returned: None, no change from Day 3
  • Burros returned: None, no change from Day 3
  • Horse deaths: 9, up from 6 on Day 3
  • Burro deaths: None, no change from Day 3
  • Horses shipped: 578, up from 366 on Day 3
  • Burros shipped: 2, up from 1 on Day 3

The figures above are based on the daily reports.  The number of horses shipped doesn’t match the total at the gather page.

Two horses were put down on Day 4 due to pre-existing conditions.  A mare jumped out of a pen on Day 5, ran through fencing and was later found dead.

The horse death rate is 1.1%.

The horse total includes 308 stallions, 352 mares and 127 foals.

Youngsters represented 16.1% of the horses captured.  Of the adults, 46.7% were male and 53.3% were female.

The herd can’t be growing at a rate of 20% per year with a birth rate of 16%.  A better estimate would be 11% per year, assuming a death rate of 5% per year.

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

Trapping continued at Bull Flat in Lassen County.

The HMA is subject to permitted grazing.
