Wild burros are small but hardy equines capable of surviving in challenging environments.

They came to this country as pack animals and helped to build the West. Used by miners during the Gold Rush of the 1800s, many of these tough little donkeys were later abandoned, but found ways to survive some of the most extreme, unforgiving terrain in the American West. Resilient and able to feed on desert vegetation, herds of wild burros now face the same threats as wild horses.

Samson, a burro adopted by Robin Mock
“He has been a wonderful addition to our rescue ranch here in Goldendale—he is loved by all and keeps us entertained. Interestingly, he has never uttered one bray. I keep waiting for him to discover he has a ‘voice’ but so far he has remained silent.” – Robin Mock of Zephaniah’s Promise Ranch in Washington on Samson, the burro she adopted after reading about the Platero Project.

We're working to keep these noble creatures wild and free by reducing the need to capture and place them in captivity.

We’re working with the Bureau of Land Management* to better understand how to manage wild burro populations using humane, non-lethal methods, such as fertility control, through initiatives like the Platero ProjectLearn about the vaccine that’s helping us help wild burros and horses.

Burros get some of their water needs from their diet of desert plants, but they often go a long time without drinking. When they need to rehydrate, they will sometimes find and dig their own wells in the dry desert soil.
