Jack,
Six years ago today, American Wild Horse Conservation (AWHC) relaunched the world’s largest humane fertility control program for wild horses on Nevada’s Virginia Range!
Since then, our team, powered by an incredible group of volunteers and supporters like you, has been working tirelessly to protect wild horses with humane conservation solutions that keep wild horses wild!
So today, we’re celebrating what we’ve accomplished together:
✅ 67% reduction in the foaling rate in 2024 compared to 2020
✅ 2,692 individual mares treated
✅ 0 helicopter roundups
✅ The Virginia Range wild horses still roam free on the range
All of this is possible thanks to PZP, a scientifically proven fertility control vaccine that is administered remotely. It’s safe, reversible, and doesn’t interfere with the horses’ natural behaviors or family bonds — allowing them to live wild, as nature intended.
This lifesaving program has changed countless lives — including Zinnia's, the mare we told you about last week who’s stayed healthy and free on the range for years thanks to our fertility control program. Through stories like hers, we’re proving that there is a better way to manage wild horse populations.

We’re working to expand this humane model to more herds across the West. But we can’t do it without your support. Will you make a donation today in honor of 6 years of keeping wild horses wild on the Virginia Range?
Thank you for being part of this movement.
With gratitude,
American Wild Horse Conservation
