The capture goal has been achieved.

A stallion was euthanized on Day 6, followed by two more on Day 8.  A stallion died on Day 8 of a broken neck.  The death rate increased to 2.9%.

The cumulative total includes 180 stallions, 197 mares and no foals.

The absence of youngsters implies a negative growth rate.  The herd is getting smaller, without the aid of helicopters, which is what the advocates are trying to accomplish in other areas with the Montana Solution.  A growth rate of 20% per year is often used by land managers to predict herd sizes.

Of the adults, 47.7% were stallions and 52.3% were mares.

Body condition scores were not reported.

The location of the trap site within the HMA was not provided.

Twenty stallions were released on Day 8 to an undisclosed location.
