Two horses were euthanized on Day 18.  The death rate is 0.9%.

The cumulative total includes 595 stallions, 641 mares and 177 foals.  The number of mares captured on Day 14 was changed from 14 to 19.

Youngsters represented 12.5% of the horses captured, consistent with a herd growth rate of 8% per year, assuming a 5% death rate.  A growth rate of 20% per year is often used by land managers to predict herd sizes.
