This is due primarily to predation by feral cats, and are also effected by habitat loss, human developments and rats and hunting which have all led to population declines since 1995/1996.To preserve the species it has been recommended that the feral cats be removed and further research be conducted. Although protected under Mexican law they are commonly poached by hunters legally hunting invasive goat species.
