The figures above are based on the daily reports.
The sidebar says 1,757 shipped. If that figure was used, there would be 153 unaccounted-for horses.
The death rate is 1.2%.
The capture total includes 726 stallions, 773 mares and 454 foals.
Youngsters represented 23.2% of the animals gathered, consistent with a herd growth rate of 18% per year.
Of the adults, 48.4% were male and 51.6% were female, no indication of an abnormal sex ratio.
Body condition scores were not given.
The location of the trap site was not disclosed.
The name of the contractor was not provided.
Three HMAs are affected.
Twelve mares have been treated with GonaCon Equine. The plan calls for up to 50 to receive the pesticide and be returned to the range with up to 50 stallions.
The roundup supports three tenets of rangeland management.
Resources liberated to date:
- Forage: 23,196 AUMs per year
- Water: 19,330 gallons per day
The Complex supports livestock equivalent to 3,730 wild horses, so it’s always at 4.2X AML or more.
