Population control methods for wild horses are essential for maintaining ecological balance and ensuring the health of both horse herds and their habitats. The American Wild Horse Campaign (AWHC) advocates for humane solutions, primarily through the use of the Porcine Zona Pellucida (PZP) vaccine, a scientifically proven fertility control method. PZP is administered via remote darting and has shown to effectively reduce population growth rates without harming the horses' natural behaviors. This approach contrasts with traditional methods like mass roundups, which can lead to increased population growth due to compensatory reproduction. AWHC's initiatives, particularly in the Virginia Range, demonstrate the success of these methods in managing wild horse populations sustainably.
