The incident began on September 1. Gather stats through September 9:
- Type: Emergency
- Method: Helicopter
- Horses captured: 631, up from 501 on Day 7

A colt was euthanized on Day 8 due to pre-existing conditions, lifting the death rate to 0.3%.
Gather operations occurred outside the HMA on Day 9. The project area is much larger than the HMA, as shown on the map in Appendix A of the Final EA (page 62 in the pdf).
The roundup is not over, as reported by some news outlets.
The breakdown between stallions, mares and foals captured on Day 9 was not provided.
As of Day 8, foals represented 12.7% of the horses gathered. Of the adults, 43.1% were male and 56.9% were female.
The low percentage of foals may be due to the darting program. The gap between males and females may indicate the sex ratio of the herd is not 1:1 (50/50).
Body condition scores were not reported.
Day 9 ended with 108 unaccounted-for animals.
