Humans and habitat destruction pose the greatest threat to Mexican wolves.
Misconceptions and myths are the biggest problems for lobos. Despite the facts that Mexican gray wolves are responsible for less than one percent of livestock deaths each year and have never attacked a person, they are often resented and feared in communities near the recovery area in southern Arizona and New Mexico. While a majority of people in those states support wolf recovery, illegal killings continue to be the leading cause of death for lobos. The small population is also threatened by inbreeding, catastrophic events like diseases and fires, and by the lack of a scientifically sound plan for their expansion and recovery.
