Horses
A stallion was put down on Day 12 for lameness along with a foal for deformed legs. A filly died of a broken neck.
On Day 13 a stallion died of a broken neck, lifting the death rate to 2.3%.
The capture total includes 285 stallions, 299 mares and 143 foals.
Youngsters represented 19.7% of the animals gathered, consistent with a herd growth rate of 15% per year. Land managers typically use 20% per year to predict herd sizes and management actions.
Of the adults, 48.8% were male and 51.2% were female.
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: 10,860 AUMs per year
- Water: 9,050 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.
