The incident concluded yesterday with 189 horses captured, 188 shipped, none released and one dead.
There were no unaccounted-for animals.
The capture and removal goals were 166 and 154, respectively.
The death rate was 0.5%.
The average daily take was 31.5.
The capture total included 57 stallions, 99 mares and 33 foals.
Youngsters represented 17.5% of the animals gathered, consistent with a herd growth rate of 12% per year.
Of the adults, 36.5% were male and 63.5% were female, results that don’t correspond to a simple random process centered at 50% males / 50% females.
The Swasey sex ratio may be skewed in favor of females, a common problem in herds treated with PZP, but the HMA does not appear in the first part of the June 3 roundup schedule for nonmotorized removal.
The HMA is subject to permitted grazing. The roundup liberated 2,268 AUMs per year, giving new hope to the poor ranchers.
The number of horses removed depends on the number returned.
The schedule indicates that up to 10 mares will be treated with GonaCon Equine and be returned to the range with up to 10 stallions.
A news release, if published, may clarify this.
