The death rate is 0.6%.

The capture total includes 407 stallions, 408 mares and 188 foals.

Youngsters represented 18.7% of the animals gathered, consistent with a herd growth rate of 14% per year.

Land managers often use a growth rate of 20% per year to predict herd sizes and management actions.

Of the adults, 49.9% were male and 50.1% 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: 12,036 AUMs per year
• Water: 10.030 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.
