The roundup ending in January 2021 yielded 18.2% foals. The page does not indicate how many mares were treated with PZP-22 and returned to the HMA.
The roundup ending in January 2025 produced 1.5% foals. Twenty-three mares were treated with PZP and released.
If the pattern continues, the herd will vanish. A birth rate of five to six percent is needed to keep up with deaths.
At last week’s WHBAB meeting, the executive director of the Campaign Against America’s Wild Horses said the roundup would not be necessary if the BLM had accepted her proposal to snuff out new life with fertility control.
The plan was rejected so why is the foal count so low?
