The Mexican desert bighorn sheep (Ovis canadensis mexicana) became extinct from the state of Chihuahua during the 1960s.

La Guarida Ranch was acquired in 1981 with the purpose to reintroduce the desert sheep to its original and historic habitats.

Today the Ranch has around 400 animals and has reintroduced the desert bighorn sheep to other ranches in the state of Chihuahua.
