Why are gray wolves found mainly in remote parts of the northern Sierra Madre Occidental?

Gray wolves are found primarily in remote parts of the northern Sierra Madre Occidental because their historical range was drastically reduced due to human activity.12

For centuries, wolves were widely perceived as threats to livestock and competitors for big game, leading to intensive eradication efforts across Mexico and the United States using every available method. As a result of this persecution and significant habitat degradation, populations were severely depleted, forcing the remaining animals into isolated, remote wilderness areas where they could avoid human contact.1234

While wolves are capable of thriving near human populations when not excessively persecuted, the historical pressure they faced has restricted their presence in the Sierra Madre to these secluded northern regions. Conservation efforts, including habitat protection and the management of endangered species like the Mexican gray wolf, continue to focus on stabilizing these populations.13254
