A mare died of a broken neck on Day 14 while being transported in a trailer.  Another mare died of a brain aneurysm but no details were given.  A foal was put down for a spinal deformity.

The death rate is 0.6%.

The capture total includes 876 stallions, 953 mares and 418 foals.

Youngsters represented 18.6% 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, 47.9% were male and 52.1% were female.

Body condition scores were not given.

The location of the trap site is not known.

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

  • Forage: 26,964 AUMs per year
  • Water: 22,470 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.
