The figures above are based on the daily reports.
Horses
The death rate is 2.2%.
The capture total includes 428 stallions, 439 mares and 194 foals.
Youngsters represented 18.3% of the animals gathered, consistent with a herd growth rate of 13% per year.
Of the adults, 49.4% were male and 50.6% were female, results that could be produced by a simple random process centered at 50% males / 50% females.
Body condition scores were not given.
Burros
The capture goal has been reached.
More burros were processed than caught, throwing the numbers out of balance.
Captured – Shipped – Released – Dead = 360 – 353 – 0 – 8 = -1
The death rate is 2.2%.
The capture total includes 186 jacks, 152 jennies and 22 foals.
Youngsters represented 6.1% of the animals gathered.
Of the adults, 55% were male and 45% were female.
General
The location of the trap site is not known. Five HMAs are involved.
The Complex is subject to permitted grazing. Resources liberated to date:
- Forage: 14,868 AUMs per year
- Water: 12,390 gallons per day
The June 3 schedule indicates that 40 mares will be treated with a fertility control pesticide but this is not acknowledged at the gather page.
There are no such plans for the burros.
The roundup supports three tenets of rangeland management.
