Shackleford Herd Declined Sharply in 2025

Your faithful public servants released the report through one of their media cronies, hoping for favorable treatment, instead of posting it to their website.

As of this morning, the 2024 update tops the list.

At the end of 2025 there were 102 horses on Shackleford Banks, down from 119 at the end of 2024, according to the 2025 update.

The herd consisted of 61% females and 39% males.

The expected range of variation for either sex, assuming they’re equally likely to occur, is 35.1% to 64.9% according to the following relationship, where n = 102 and p-bar = .5.

Although there is some evidence of an abnormal sex ratio, it doesn’t provide a basis for action.

Seven foals were born in 2025.  One died and two were removed, leaving four to offset the 20 adults that died.

The net change is -16, which would put the year-end population at 103.

The size of the breeding population and the number of sterilized mares were not given.

The pesticide of choice is PZP although this is not stated in the report.
