The incident began on July 9. Results through July 17:
- Scope: Spruce-Pequop, Goshute, Antelope Valley HMAs
- Purpose: Pest control, resource enforcement, rancher protection
- Target: Horses
- Type: Planned
- Method: Helicopter
- Category: Cruel and costly*
- Better way: Poison mares with ovary-killing pesticides*
- Captured: 289, up from 249 on Day 7
- Average daily take: 32.1
- Capture goal: 2,000
- Removal goal: 2,000
- Returned: None
- Deaths: 4, no change from Day 7
- Shipped: 234, up from 193 on Day 7
The figures above are based on the daily reports, not the totals posted by the BLM.
The number of horses shipped to date, based on the daily reports, is 234, compared to a total of 240 in the summary.
The trap may have been moved on Day 8, possibly to another HMA, because no horses were captured and none were shipped on Day 9.
The death rate is 1.4%.
The capture total includes 93 stallions, 146 mares and 50 foals.
Youngsters represented 17.3% of the animals gathered.
Of the adults, 38.9% were male and 61.1% were female. The proportions fall outside the expected range of variation from a simple random process centered at 50% males / 50% females with a sample of 239 adults. The disparity might be explained by the contractor targeting family bands.
A 17% birth rate corresponds to a herd growth rate of 12% per year.
Land managers often use growth rates of 20% per year to predict herd sizes and management actions.
Body condition scores on Day 9 were 4.
The location of the trap site was not disclosed.
The HMAs and surrounding lands are subject to permitted grazing.
*According to advocates.
Day 9 ended with 51 unaccounted-for animals.
There are no plans to treat captured mares with fertility control pesticides and return them to the area.
Other statistics:
- Forage liberated to date: 3,468 AUMs per year
- Water liberated to date: 2,890 gallons per day
- Forage assigned to livestock: Unknown
- Horses displaced from area by permitted grazing: Unknown
- True AML: Unknown
- Stocking rate at new AML: Unknown
- Horses removed because of drilling and mining: Ask the advocates
Overpopulation means more horses than allowed by plan, not necessarily more horses than the land can support.

BLM is just a cruel, cold ruthless corrupt organization. They do not care about anything but the green going into their fat wallets and keeping their rancher buddies happy. It’s all one big sick game to them. Horses lives do not matter to them. Thus corruption needs to be shut down.
