Jack,

Here at American Wild Horse Conservation (AWHC), our mission is to protect America’s wild horses and burros, ensuring their freedom and safeguarding their future on our public lands.

One of our most impactful initiatives is our PZP fertility control program. PZP is a scientifically-proven fertility control vaccine given to female horses on the range via remote darting. It’s administered in a two shot process — the first is a primer, which is then followed by a booster approximately two weeks later. The vaccine prevents fertilization and pregnancy via an immune response that does not affect the horse’s hormonal system — all for just $30 per dose.

Our humane fertility control program is one of the largest and most successful of its kind in the world. We are also proud to partner with the federal government to implement fertility control on the Cedar Mountain herd in Utah — an inspiring example of collaboration and how fertility control can work at scale. 

Jack, while a federal grant covered a substantial portion of this program, we recently learned the grant will not be renewed. And now we need your help to keep our programs fully funded and keep the Cedar Mountain wild horses wild.

Your gift today will help us:

• Deliver safe, effective fertility control to wild mares through remote darting
• Support trained field teams who track, execute, and document these efforts
• Keep wild horses in the wild, where they belong

Jack, this work is only possible because of the continued support of people like you. A gift of just $30 today can save a life tomorrow. Will you make a donation today to help us continue our PZP program?

Thank you,

Team AWHC
