A foal was dispatched for a broken leg on Day 21.  A stallion was put down for a reproductive organ injury.  NOTE: All stallions identified for removal will have reproductive organ injuries.

The death rate is 0.6%.

The capture total includes 1,005 stallions, 1,101 mares and 470 foals.

Youngsters represented 18.2% of the animals gathered, consistent with a herd growth rate of 13% per year.  Land managers often use a growth rate of 20% per year to predict herd sizes and management actions.

Of the adults, 47.7% were male and 52.3% were female.

Body condition scores were not given.

The location of the trap site is not known.  Four HMAs are involved.

The Complex is subject to permitted grazing.  Resources liberated to date:

  • Forage: 30,912 AUMs per year
  • Water: 25,760 gallons per day

The June 3 schedule indicates that 20 mares will be treated with fertility control pesticides and returned to the range but this is not discussed at the gather page.

The roundup supports three tenets of rangeland management.
