Sand Wash Roundup Day 11

The incident began on September 1.  Gather stats through September 11:

  • Type: Emergency
  • Method: Helicopter
  • Horses captured: 667, up from 631 on Day 9
  • Average daily take: 60.6
  • Capture goal: 783
  • Removal goal: 733
  • Returned: 53, up from 1 on Day 9
  • Deaths: 2, no change from Day 9
  • Shipped: 591, up from 520 on Day 9

The death rate is 0.3%.

Gather operations are now occurring outside the HMA.  The project area is much larger than the wild horse area, as shown on the map in Appendix A of the Final EA (page 62 in the pdf).

The breakdown between stallions, mares and foals captured on Day 9 has not been provided.

Foals represented 13.5% of the horses gathered, excluding Day 9.  Of the adults, 42.7% were male and 57.3% were female.

The low percentage of foals may be due to the darting program.  With most of the herd captured, females outnumbered males by a ratio of 1.3 to 1.

Body condition scores were not reported.

Day 11 ended with 21 unaccounted-for animals.
