Mission: Ensure the protection and humane management of the Salt River wild horses.

“The Salt River wild horses are a living piece of our Arizona history, a remnant of our pioneering American spirit,” said Simone Netherlands, President of the SRWHMG. “We are so lucky to still have them here”.

The Salt River Wild Horse Management Group is ecstatic to be able to implement humane management solutions for this herd, to ensure that not one Salt River wild horse ever has to be rounded up from the Salt River.

“We look forward to continuing our successful public/private partnership with federal, state and local officials to protect the Salt River wild horses a well as the safety of public who loves them,” Netherlands continued, promising management of the horses by and for the public.

The SRWHMG, with its 100 volunteers, monitors the horses on a daily basis and will implement a management program under the Arizona Department of Agriculture, with the following components:

– A humane birth control program to stabilize and reduce population growth in the Salt River wild horse herd;

– Emergency feeding and diversionary watering as needed during drought;

– Maintenance of fences and gates to keep wild horses off the roads,

– Rescue and sanctuary of injured wild horses when needed.

Also recently, at the group’s request, the Maricopa County Department of Transportation began to make safety improvements on Bush Highway to reduce the chances of horse-vehicle collisions.

As a result of record breaking drought in Arizona, we are currently in an emergency feed protocol under authorization from the Arizona State Agriculture Department. Please click on Emergency Feed Protocol to help.

The Cause: prevent their removal.

This fight has been about keeping a small piece of wild for future generations to come, and managing it humanely and responsibly. When we started this campaign for their freedom we had no idea that it would touch hundreds of thousands of Arizonans and Americans so deeply. We are forever grateful that this amazing herd found their voice with the public of Arizona and all of its legislators, politicians as well as Governor Doug Ducey.  While so close to being gone forever, the Salt River wild horses are now protected under the Salt River Horse Act which establishes that the Salt River wild horses are not stray livestock and makes harassing and killing them illegal.

Humane Birth Control

Our humane Birth control protocol has been authorized by the Arizona State Agriculture Department. PZP (Porcine Zona Pelucida) immuno-contraception is the acceptable form of birth control for wild horses, as it does not harm nor influence their wild behaviors and herd dynamics. PZP can be darted without capturing horses and it prevents fertilization for one year. By implementing a fertility control protocol with our certified darters, we can stabilize the population humanely. The young mares will get a chance to mature before foaling and the older mares can get a break from having babies, which improves their overall health. The goal of the program is for each horse born in the wild, to be able to stay in the wild.

Background: When the notice came out for the herd’s roundup and removal in 2015, we were devastated. We knew that we would need an unprecedented public outrage to prevent the annihilation of this historic herd. We gave it our all; we alerted and informed the public and the press, we held rallies and protests, we filed a lawsuit and we negotiated with the Forest Service. What happened next was amazing, it was the unprecedented public outrage we needed, and then some- the people of Arizona and its politicians gave these iconic wild horses a voice. Under continued pressure, the Forest Service agreed to rescind the impound notice. Together, we changed the course of history for the Salt River wild horses, who now have a legal right to live on the Salt River in Arizona and are protected under State law.
