Wild horses and donkeys dug desert wells used by 57 vertebrate species

Researchers conducting a study in the Sonoran Desert have observed wild horses and donkeys digging wells that provide essential water to 57 different vertebrate species. These animals excavate the ground to reach groundwater, creating accessible water sources that prove critical for local wildlife survival during dry periods.

The presence of these wells significantly increases water availability in the arid environment. By facilitating access to water, the digging behavior of these wild equids creates a beneficial impact on the biodiversity of the desert ecosystem.
